BMW iX M60 takes BMW M into electric era

For the brands that sell high-performance cars, going electric has added challenges. They need to not only ensure that the electrically-powered cars offer the same sort of performance levels their customers expect from their brand but also new requirements like charging times and range. The latter especially was not so important before as customers are okay with high fuel consumption and can refuel as needed. With an electric car, you cannot ‘refuel’ as easily and at this time, it still takes a while to recharge battery packs (although that time is getting shorter),

For a company like BMW M, which has built up a reputation producing cars with superlative performance, going electric meant that they had also to be able to offer the same kind of performance. Drawing on the BMW Group’s expertise in the field, BMW M also had its own specialized skills to develop electric cars worthy of the M badge.

3.8 seconds from 0 to 100 km/h
The first BMW M automobile designed for purely electric mobility from the outset – the new iX M60 – should provide reassurance to fans of M. With an output of 455 kW/619 ps and maximum torque of up to 1.015 Nm, it has a claimed standstill to 100 km/h time of 3.8 seconds and can go over 250 km/h but is limited to that top speed. With a fully charged battery pack, factory tests have shown it to be able to travel up to 566 kms.

The 111.5-kWh battery pack can be recharged using a DC fast-charger and add 150 kms of range within 10 minutes. Leave it connected to the charger longer and after 35 minutes, the energy content can be up to 80% from 10%.

The suspension technology of the iX M60 includes a double-wishbone front axle, a 5-link rear axle and electric steering with Servotronic function and variable ratio. In addition, there’s adaptive dual- axle air suspension with electronically-controlled shock absorbers. The dual axle air suspension ensures the optimum vehicle height at any speed, regardless of the load. The air supply to the suspension is regulated individually for each wheel and can thus also compensate for uneven loading.

The damper forces are adaptively controlled with an M-specific characteristic via continuously adjustable valves, which take into account longitudinal and lateral acceleration, road speed and steering angle as well as body and wheel acceleration on the front axle in order to activate the required damper force within a few milliseconds.

BMW IconicSounds Electric
Like all BMW i models, the iX M60 will have BMW IconicSounds Electric with specific characteristics for its M exclusivity. The emotional soundtrack that the occupants will hear was created in a collaboration between film music composer and Academy Award winner Hans Zimmer and BMW Group Creative Director Sound Renzo Vitale.

Even pressing the START/STOP button is acknowledged with an inspiring acoustic signal. While driving, the BMW IconicSounds Electric provide authentic feedback to every movement of the accelerator pedal. The sound of the drive is characterized by a particularly energy-charged sound development. The sound characteristics are based on the setting selected with the Driving Experience Control Switch.

Milestone for BMW M
The debut of the iX M60 marks a milestone in the history of BMW M, 50 years old this year, as it enters the segment of electrified performance cars. Like all recent BMW fully electric models, the architecture is completely new and designed for electric powertrains. So the full benefits are exploited and performance can be optimized. The iX M60’s performance, efficiency and range also benefit from its optimized aerodynamics which give it a Cd of 0.26 (in Sport Mode).

Lightweight construction principles
The vehicle concept of the iX provides an ideal basis for an all-electric SAV with high-performance characteristics. Both the body structure and the design principle as well as suspension set-up are geared towards combining ride comfort with sporty handling characteristics. The aluminium spaceframe concept and the carbonfibre cage with carbonfibre reinforced plastic (CFRP) in the roof, side and rear sections are an intelligent mix of materials that combines increased rigidity with optimized weight.

The use of CFRP to reduce weight has a long tradition at BMW M. The particularly lightweight high-tech material already achieved great results in combining engine performance and weight in the M3 CSL which was introduced in 2003. In fact, BMW M pioneered the use of CFRP in large-scale automotive production and today uses it in numerous current models as part of the intelligent lightweight construction principle.

The high-voltage battery is located deep down in the underbody, lowering the vehicle’s centre of gravity for agile handling as well as balanced axle load distribution. Like the other models, the iX M60 also has an extensive range of driver assistance systems. A new generation of sensors, a new software stack and a powerful computing platform also provide considerable potential for consistently advancing automated driving and parking functions – with level 3 functionality in the medium term.

Future modular system
The iX M60 combines its typical M performance characteristics with the exceptionally advanced technology of the BMW Group’s new future modular system in the areas of automated driving, operation, connectivity and digital services. This creates an experience of premium mobility that is unique in the competitive environment. The completely redeveloped interior architecture also contributes to this, creating an exceptionally generous feeling of space.

BMW Group Malaysia moves into next phase of electrification with new BMW i model range

This car doesn’t fly but it could replace the budget airline aircraft

Before 2020, flying had become commonplace with low-cost carriers making it possible for almost anyone to fly. For Malaysians, heading off the Penang or the East Coast for the weekend was replaced by quick trips to Phuket in Thailand or Bali in Indonesia. Then COVID-19 attacked the planet and that changed things. People are flying again but it’s no longer the same and with the strict procedures and quarantines in different countries, it is also not enjoyable.

So Car Design Research (CDR — a UK based agency) has come up with the idea of the Budget Airline Car. No, it’s not another flying car but it is aimed at providing alternative to flying, short-haul in particular, by using a large super-efficient low-cost electric car. Such a car might be appealing for people who don’t want to be close to hundreds of others in airports and aircraft cabins, or who want to help save the planet by not using the most environmentally damaging form of transport: the short-haul flight.

Conceived during the lock-down in Britain last year, the Budget Airline Car is a concept for a new type of car design that would produce only 2% of the emissions per passenger compared to a short-haul flight. The core concept was developed closely with CDR design associates Yichen Shu in China and Aditya Jangid in India, both of whom then designed subtly different exterior design themes.

Today, an increasing number of new cars are electrified, full of connected services, with increasing autonomous capabilities. But. in design. they are not so different to cars from 20, even 50, years ago. Almost all still seat the driver and passenger on separate seats up front, and two or three behind, with one separate space at the rear for luggage accessed from outside.

It’s a formula that works, so why change it? Well, there are two big reasons: because the way people live has changed since this design pattern was established 100 years ago; and because new technologies are unlocking the potential for design change. There’s a third and fourth reason to change too: because globally we are facing a climate emergency, and because we are in the midst of a pandemic — both huge imperatives for truly new types of car design.

The CDR team looked at this context of a fast-changing world and saw opportunities for car design. They came up with 6 new car types that would be enabled by new technologies, and that would be part of uniquely pertinent future scenarios. One of these focused on being an alternative to the short-haul flight — the form of transport most at the heart of today’s imperatives to change because it creates an increasingly untenable level of environmental damage. COVID-19 concerns also make being in airport queues and airplane cabins less desirable.

So, the core concept for the Budget Airline Car is for a shared super-efficient car to be offered by budget airlines or hire car brands as an alternative service to short-haul flights. A short-haul flight is defined as a journey of up to 3 hours, or up to 1,100 kms. That’s the flying distance from Kuala Lumpur to Bangkok or Jakarta.

The car would seat 6 people in 3 rows and as passengers may not know each other (just as on a flight), each would have a dedicated seat with their cabin baggage securely stored within easy reach. This would have greater privacy and space than afforded by existing cars’ second and third row seats.

This three-seat row layout can be realised within an overall length of 5 metres, despite each seat space being equally large, because of the benefits of compact electric motors. The 2-person wide layout also contributes to a reduced frontal area compared to a car designed to seat three people side-by-side.

The electric powertrain would be developed for long-distance mid-speed cruising, rather than high performance, and the design would prioritise aerodynamics. The length of 5 metres would make the Budget Airline Car as long as a current Volvo XC90, but its 1.8-metre width and 1.5-metre height would give it 20% less frontal area. This, along with a more slippery shape/lower drag coefficient, would make it markedly more aerodynamic and thus more energy-efficient.

Passengers could share the driving, with good driving incentivised by the shared-economy digital platform that they access the service through (akin to eBay, Airbnb, and other shared service platforms). A suite of advanced driver assistance systems (ADAS) would aid safety, with fully autonomous drive also becoming available over time.

While the idea may not be as useful in Malaysia, other than going from Kuala Lumpur to Bangkok (and places in between), the design would still offer possibilities for domestic travel around the peninsular. The highway network is already quite well developed so journeys can be smooth and quick. Perhaps instead of being positioned in comparison the a ‘budget airline’, the car could be a premium form of transport that is an alternative to a bus or taxi.

The power of touchscreens and dashboards of the future

Volvo will introduce unsupervised motoring in California first

Carmakers wanting to enter the US market have often found that the west coast state of California is a good place to start. It seems that consumers there are receptive to new trends and new cars, so Volvo Cars will introduce its unsupervised autonomous driving feature, Ride Pilot, to customers in the state of California first.

‘Unsupervised’ would mean that Ride Pilot offers the highest level of autonomous motoring where humans do not have to be involved at all. It’s the stuff of science fiction movies and will free up more time for the occupants to do other things. Whether we can call it ‘driving’ any longer is something that will need to be debated.

In tandem with the introduction of Ride Pilot, the company is also setting a new standard for safety, with over-the-air (OTA) software updates in combination with a state-of-the-art sensor set-up. The software is developed by autonomous driving software company Zenseact, together with Volvo Cars’ in-house team of developers, and developers from Luminar, one of its technology partners.

The sensor set-up consists of more than 2 dozen sensors, including Luminar’s cutting-edge Iris LiDAR sensor, which will be tightly integrated with the developed software. Luminar’s LiDAR sensor will complement 5 radars, 8 cameras and 16 ultrasonic sensors in Volvo Cars’ upcoming fully electric SUV. This standard sensor set-up provides excellent vision and perception reliability. Together with continuous, over-the-air software rollouts, the system will ensure full redundancy and enable Volvo Cars to achieve safe autonomous driving with Ride Pilot.

For autonomous motoring to be safe with no supervision by humans, the vehicle will have to be able to scan all round with various sensors to detect other vehicles and hazards. The sensors will include cameras mounted in the windscreen like the ones shown below.

Rigorous testing and verification
While this software-sensor combination, and the safety it enables, will be standard, available from day one on the new SUV and improved over time, Ride Pilot will be made available to customers only once it has gone through Volvo Cars’ rigorous verification and testing protocol. This includes validation of the technology as safe for use on highways in a number of varying conditions. This new flagship for the company will be revealed later this year.

As part of this verification process, Volvo Cars is already testing autonomous driving functionalities on roads in Sweden together with Zenseact, and collecting data across Europe and the USA. By the middle of this year, the company intends to begin testing on roads in California (pending approvals from relevant authorities), where the climate, traffic conditions and regulatory framework provide a favourable environment for the introduction of autonomous driving.

But where and how far autonomous driving will be permitted is not known yet. In some countries where autonomous vehicles are permitted to operate, only limited sections of public roads can be used. On such roads, the surrounding environment is properly prepared to ensure that the imagery systems can correctly function to detect and identify road hazards and signage.

More free time on a journey
The name ‘Ride Pilot’ implies what the driver can expect: when the car is driving on its own, Volvo Cars takes responsibility for the driving, offering the driver comfort and peace of mind. By using Ride Pilot, drivers will be able to free up time while driving, and spend it on secondary activities such as reading, writing, working or socialising. The feature can also help drivers arrive at their destination rested and recharged, by reducing the mental strain that may come with driving, especially in traffic jams or heavy traffic.

Without the need to supervise what the car is doing, the driver will be able to do other things like read or even talk on a phone without breaking any law. Perhaps the occupants could even sleep on the journey – but can it be called ‘driving’ then?

“We are proud to announce the planned US launch of our first truly unsupervised autonomous driving feature, as we look to set a new industry standard for autonomy without compromising safety,” said Mats Moberg, Head of Research and Development at Volvo Cars. “Having Zenseact’s brand-new AD software and Luminar’s LiDAR standard in our new fully electric SUV is a game-changer for Volvo Cars, as well as for automotive safety and autonomous driving.”

Human drivers use two eyes, autonomous cars need three eyes

Chrysler Airflow Concept begins carmaker’s transformation of range to fully electric by 2028

Although Chrysler, one of the three original American carmakers to survive to this day, has had electrified models for some years. By 2025, it will start selling its first battery electric vehicle (BEV), with plans to change its entire product range to BEVs by 2028. As part of the Stellantis Group, formed only one year ago, the carmaker will serve at the forefront of Stellantis’ transformative, sustainable mobility technology.

The Airflow Concept displayed at CES 2022 in Las Vegas this week provides a preview of what will come. With leading-edge drive-system technology, intuitive AI and connected vehicle technology, the concept car is said to be able to travel 560 – 650 kms on a fully charged battery pack which can be fast-charged.

Reinventing the customer experience
However, the new connected car isn’t simply about moving from point A to point B. It is said to reinvent the customer experience by integrating the STLA Brain platform and STLA SmartCockpit to deliver seamless connectivity for the driver and passengers. The concept creates a connected hub that brings a consumer’s digital lifestyle into the cabin, using advanced technology to create a customized space for each occupant.

“The Chrysler Airflow Concept represents the start of the brand’s journey toward a fully electrified future. It is the result of a thoughtful synthesis of the full arsenal of Stellantis’ connected vehicle technology – inside and out,” said Ralph Gilles, Chief Design Officer – Stellantis. “The design features a decisively elegant aerodynamic exterior and a modern, sophisticated interior that takes the customer on a new level of digital delight.”

Dynamic design
The sculptural, expressive design of the Airflow Concept envisions the next generation of premium transportation. It delivers a first-class travel experience that balances technological needs within a serene environment. The silent electric ride supports the sleek design aesthetic, with the concept’s dramatic expression completed by an Arctic White body colour that conveys a sense of calm and serenity.

The dynamic design proportion has a low ride height and streamlined, two-tone roof line that achieves an elegant yet athletic profile while also increasing travelling range. A long wheelbase and wide track, along with large 22-inch wheels and tyres, are enhanced visually with Celestial Blue accent colour cladding. The design elements work together to enable a dramatic stance and deliver excellent handling and performance dynamics.

Up front, the Airflow announces its electric aesthetic with the Chrysler wing logo tied into a cross-car grille/light blade illuminated with crystal LED lighting. A crystal LED taillight runs the full width of the vehicle, accentuating the wide stance. The Airflow Concept also features welcome, departure and animated lighting, including a unique aqua that signifies the vehicle is charging. The diffuser shape of the lower rear fascia highlights the aerodynamic, smooth underbody, a key to achieving optimum driving range.

Personalised spaces within
The Airflow Concept is designed as a space to bring people together, both physically and virtually. The interior showcases ideas for giving every passenger a personalized experience that seamlessly connects them with their digital lives, as well as the other passengers. Multi-layered, high-contrast graphics and thoughtful details provide a clean, sophisticated appearance that is safe, easy to use and easy to understand.

Using a menu-based format, screens throughout the interior can be personalized, simplified and grouped based on individuals and interests. Information on the screens can be shared with all passengers by swiping. Customization and personalization are key, whether driving or acting as a co-pilot. Each screen is thus a personalized space to access the digital world via connected entertainment, apps and downloads. Each seat also features a built-in camera, enabling occupants to participate in a group video conference call from the comfort of the Airflow cabin.

Over-the-air (OTA) updates keep Airflow Concept services current and let passengers quickly and easily add new and innovative features. The backbone of the user experience is the new electrical/electronic (E/E) and software architecture, STLA Brain. This architecture is highly flexible, breaking today’s bond between hardware and software generations. It enables software developers to create and update features and services quickly, taking advantage of capabilities built into the cockpit without waiting for a new hardware launch.

The STLA SmartCockpit, demonstrated in the Airflow Concept and built on top of STLA Brain architecture, seamlessly integrates with the digital lives of vehicle occupants to deliver AI-based applications, such as navigation, voice assistance, e-commerce marketplace and payment services.

Level 3 autonomy
Of the powertrain, Chrysler says it will be called STLA AutoDrive, which delivers Level 3 autonomous driving capabilities and will be upgradable via OTA updates. The concept features all-wheel-drive capability and is powered by two 150 kW electric drive motors (EDMs), one in the front and one in the rear. The concept is designed to accommodate larger capacity EDMs, offering the potential for future high-performance applications.

GM’s Factory ZERO starts production of only electric vehicles

You can have a different colour for your BMW iX every day!

In the 1960s, James Bond’s Aston Martin had changing numberplates and in 2021, BMW’s iX Flow featuring E Ink has changing body colours. But just like the feature on James Bond’s car, don’t expect it to be offered on BMWs anytime soon. It is a demonstration of future technology for a model displayed this week at CES 2022 (the consumer electronics trade show in Las Vegas) to show how digitisation can be used to adapt the exterior of a vehicle to different situations and individual wishes.

The fluid colour changes are made possible by a specially developed body wrap that is tailored precisely to the contours of the all-electric Sports Activity Vehicle from BMW. When stimulated by electrical signals, the electrophoretic technology brings different colour pigments to the surface, causing the body skin to take on the desired colouration.

More sophisticated personalisation
The use of innovative E Ink technology opens completely new ways of changing the vehicle’s appearance in line with the driver’s aesthetic preferences, the environmental conditions or even functional requirements. The technology thus offers unprecedented potential for personalisation in the area of exterior design and the iX Flow demonstrates this potential to impressive effect.

Already today, the colour chosen for a car is an expression of the driver’s personality. The choice of exterior finishes available for current BMW models covers a wide colour spectrum. In this way, the longing for a wildly expressive, extravagant, or sporty appearance on the outside can be taken into account as well as the desire for an understated, subtle or elegant appearance.

Against this background, the BMW Group is driving the development of the technology so that a new form of personalisation can be experienced both on the outside and in the inside of future production vehicles. Apart from a greater degree of personalisation, a customer will also not have to settle for just one colour – he or she can have many more for different occasions!

“This gives the driver the freedom to express different facets of their personality or even their enjoyment of change outwardly, and to redefine this each time they sit into their car,” said Stella Clarke, Head of Project for the BMW iX Flow featuring E Ink. “Similar to fashion or the status ads on social media channels, the vehicle then becomes an expression of different moods and circumstances in daily life.”

Increased efficiency too
A variable exterior colour can also contribute to wellness in the interior and to the efficiency of the vehicle. This is done by taking account of the different abilities of light and dark colours when it comes to reflecting sunlight and the associated absorption of thermal energy. A white surface reflects a lot more sunlight than a black one. By implication, heating of the vehicle and passenger compartment as a result of strong sunlight and high outside temperatures can be reduced by changing the exterior to a light colour. In cooler weather, a dark outer skin will help the vehicle to absorb noticeably more warmth from the sun.

In both cases, selective colour changes can help to cut the amount of cooling and heating required from the vehicle’s air conditioning. This reduces the amount of energy the vehicle electrical system needs and with it also the vehicle’s fuel or electricity consumption. In an all-electric car, changing the colour in line with the weather can therefore also help to increase the range. In the interior, the technology could, for example, prevent the dashboard from heating up too much.

E Ink technology itself is extremely energy efficient (though, at this time, it would be very expensive technology). Unlike displays or projectors, the electrophoretic technology needs absolutely no energy to keep the chosen colour state constant. Current only flows during the short colour changing phase.

Millions of paint capsules
Electrophoretic colouring is based on a technology developed by E Ink that is most well-known from the displays used in eReaders like Kindle. The surface coating of the iX Flow contains many millions of microcapsules, with a diameter equivalent to the thickness of a human hair. Each of these microcapsules contains negatively charged white pigments and positively charged black pigments. Depending on the chosen setting, stimulation by means of an electrical field causes either the white or the black pigments to collect at the surface of the microcapsule, giving the car body the desired shade.

Achieving this effect on a vehicle body involves the application of many precisely fitted ePaper segments. Generative design processes are implemented to ensure the segments reflect the characteristic contours of the vehicle and the resulting variations in light and shadow. The generative design algorithms enable the necessary formability and flexibility required to tailor the ePaper exactly to the design lines of the vehicle.

Laser cutting technologies are used to guarantee high precision in generating each segment. After the segments are applied and the power supply for stimulating the electrical field is connected, the entire body is warmed and sealed to guarantee optimum and uniform colour reproduction during every colour change.

“Digital experiences won’t just be limited to displays [inside the car] in the future. There will be more and more melding of the real and virtual. With the BMW iX Flow, we are bringing the car body to life,” said Frank Weber, Member of the Board of Management of BMW AG, Development.

Sony has developed a second EV and this one’s an SUV

At CES 2020 (the major consumer electronics trade show in Las Vegas), the Sony Group announced that it would be venturing further into the mobility business, with a sleek prototype car called the VISION-S. At that time, though, what it displayed seemed to be a concept car to show off various technologies, which is also done by other electronics companies

However, the company was actually going further with the concept car and began quietly developing it into a running prototype. By CES 2021, it revealed that there was a running prototype and it was being tested on public roads and on a test track in Austria. Engineers also started verification tests of the safety and user experience of the imaging and sensing technology installed inside and outside the vehicle, along with the human-machine interface (HMI) system.

*The VISION-S 02 concept (left) joins the original VISION-S 01 prototype.*

Second prototype displayed
At CES 2022 this week, Sony has not only provided an update on the progress of the project but is also displaying a second prototype, the VISION-S 02. This has a SUV design as a new form factor and rides on the same EV/cloud platform as the original VISION-S 01 prototype. By offering entertainment experiences utilizing the large interior space and variations of a 7-seater, this new prototype will promote the accommodation of a large variety of lifestyles within a society where values are becoming increasingly diversified.

The VISION-S 02 measures almost 4900 mm long and 1930 mm wide, which is about the size of a Lexus RX300. It has 200 kW electric motors powering the front and rear wheels so there’s all-wheel drive and the claimed top speed is expected to be over 180 km/h.

Advanced sensor system
Electronics are obviously one of Sony’s strengths and it has been developing a sensors system to support the driver. The system recognizes and analyzes the surrounding environment in real-time, using sensors installed to cover all around the vehicle. These sensors include high-sensitivity, high-resolution, wide dynamic range CMOS image sensors and LiDAR sensors that accurately sense 3-dimensional space.

In addition, the system provides intuitive driver interaction in conjunction with the vehicle’s sound system and HMI system, so that the driver can accurately judge the status of the surrounding environment, such as the presence of emergency vehicles, even from inside the vehicle.

Time-of-Flight (ToF) sensors are used to provide monitoring functions for driver authentication and to watch over passengers. They also support intuitive gesture and voice commands that are intended to enhance usability of the car interface. Additionally, in order to deliver an environment that suits each user’s preferences, the vehicle will include a new function that allows users to customize the display theme and the acceleration and deceleration sounds of the vehicle.

Vehicle settings, key locks, and user settings can be synchronized by linking the vehicle to the cloud using mobile communication, including 5G communication, which features low-latency, high-capacity, and high-speed capabilities. In addition, since updates are reflected in the vehicle via over the air (OTA), it is possible to provide security and evolve service functions and value-added offerings continuously.

5G connectivity
5G driving tests were also conducted from April 2021, the next-generation network connectivity enabling a continuous connection between the in-vehicle systems and the cloud, in order to synchronize data and control signals, and update the systems OTA (Over The Air).

“Real time mobile communication turns cars into databases on wheels. In our 5G Mobility Lab, the VISION-S Prototype learns to communicate in real time. Together with Sony, we are preparing the first prototype for 5G so that in the future new features can be imported into the car over the air and with a simple software update,” said Hannes Ametsreiter, CEO of Vodafone Germany, which is collaborating with the Japanese company.

Utilizing Sony’s in-house technologies and knowledge of communication technology and security cultivated through the development of smartphones, it has positioned remote operation as an important technology in anticipation of the arrival of the autonomous driving era.

Enriching the mobility entertainment space
The seat speakers, which create a three-dimensional sound field, and the streaming service compatible with ‘360 Reality Audio’ provide an immersive music experience. The high quality would only be expected from Sony, which has a strong reputation in this field.

In addition, to provide a high-quality movie experience, the VISION-S models include the fully integrated digital video service ‘BRAVIA CORE for VISION-S’. The service enables shared or individual video playback on the front panoramic screen and individual rear-seat displays. Further extending the possibilities of in-vehicle entertainment, gaming capabilities have expanded to being able to play PlayStation games through a remote connection to a console at home, in addition to the ability to play streaming games through the cloud.

To make the best use of AI and robotics technologies, Sony will soon establish an operating company called Sony Mobility Inc., through which the company intends to explore entry into the EV market.

The most efficient Mercedes-Benz ever built – the Vision EQXX

At one time, when mention was made of ‘EV’ or electric vehicle, a small bubble shaped car might come to mind. And though electric motors do have a lot of zip, EVs were thought to be poor performers which provided basic transportation but no driving pleasure. But as we are now seeing, the EVs set to replace cars with combustion engines in coming years will continue to offer the driving pleasure that motorists enjoy, and even exhilarating performance – with zero emissions to damage the atmosphere.

And with new freedom for design due to the entirely different architecture, the stylists can come up with new forms that are sleeker than today’s cars. The Mercedes-Benz Vision EQXX concept shows us the sort of car we could be driving on roadtrips in future. It’s a concept car for now, though it is not just for show as many technological elements will likely be used in production models when they are validated and can be produced at a reasonable cost.

Range and efficiency are the key points about the VISION EQXX, achieved by having an ultra-efficient fully electric drivetrain and lightweight engineering. “The Mercedes-Benz VISION EQXX is how we imagine the future of electric cars. Just one-and-a-half years ago, we started this project leading to the most efficient Mercedes-Benz ever built. The VISION EQXX is an advanced car in so many dimensions – and it even looks stunning and futuristic. With that, it underlines where our entire company is headed: We will build the world’s most desirable electric cars,” declared Ola Kallenius, Chairman of the Board of Management of Daimler AG and Mercedes-Benz AG.

The result is an efficiency masterpiece that, based on internal digital simulations in real-life traffic conditions, will be capable of exceeding 1,000 kilometres with a fully charged battery pack. That’s a distance equivalent to going from Berlin to Paris, or from Beijing to Nanjing. Based on average distances driven per year, a driver in the USA or China would have to fully recharge the VISION EQXX only twice per month or, in Europe, just once per month.

The secret here is efficiency as the VISION EQXX uses less than 10 kWh of electrical energy to travel 100 kms. That equates to traveling 9.7 kms on 1 kWh of electrical energy. Translated into fossil-fuel consumption, this is around the golden figure of 1 litre per 100 kms/100 kms per litre or for those who remember the old measure, 282 mpg.

And it’s not about having a bigger battery either; in fact, the prototype battery pack in the concept car could easily fit into a smaller sized vehicle than the VISION EQXX. Battery technology is continuously advancing and what is used has the latest advanced developed by the German carmaker. Rather than simply increasing the size of the battery, Mercedes-Benz and the HPP team developed a completely new battery pack, achieving a remarkable energy density of close to 400 Wh/l. Overall, the battery weighs around 495 kgs.

“In effect, we fitted the energy of the EQS into the vehicle dimensions of a compact car,” said Adam Allsopp, Advanced Technology Director from HPP. “The battery has almost the same amount of energy but is half the size and 30% lighter. The battery management system and power electronics have been designed with an absolute focus on reducing losses. In achieving this efficiency milestone, we learnt a lot that will flow into future development programmes.”

Tasked with pushing the envelope of technical feasibility on all levels, the battery development team also decided to experiment with an unusually high voltage. Increasing the voltage to more than 900 volts proved an extremely useful research tool for the development of the power electronics. The team was able to gather a great deal of valuable data and is currently assessing the potential benefits and implications for future production models.

Additional energy is also draw from the sun, the original source of all energy on Earth. The electric system that powers many of the ancillaries gets additional energy from 117 solar cells on the roof. The net result of reducing the energy drain on the high-voltage system is an increase in range. On a single day and under ideal conditions, this can add up to 25 kms of range on long-distance journeys. The solar energy is stored in a lightweight lithium-iron-phosphate battery, which supplies a climate blower, the lights, the infotainment system and other ancillaries.

At its heart, efficiency means achieving more from less. The most familiar expression of automotive efficiency is that of fuel consumption or fuel economy. This is expressed in different ways depending on where we are in the world (eg litres per 100 kms, miles per gallon or kilometres per litre). Regardless of convention, they all relate units of fuel (energy) with units of distance. Electric mobility is no different in that respect, but the imperatives of electric mobility and sustainability have shifted the framework for efficiency.

For Mercedes-Benz, quantifying technological development across the board now goes beyond fuel efficiency alone. As well as meaning more range from less energy, it also means more tangible luxury and convenience with less impact on nature, and more electric mobility with less waste.

“Electric range sounds easy but is a complex technical challenge. The easiest way is to put a bigger battery in the car. However, this leads to diminishing returns due to size and weight. This is definitely not the smartest route and it’s also not the best use of scarce resources. With the VISION EQXX, we’re presenting the results of an extraordinary challenge: we pushed efficiency to a totally new level. And we explored new ways to increase the range of an electric car,” said Joerg Bartels, Vice-President for Vehicle Engineering and Overall Vehicle Functions.

The electric drive unit is a dedicated unit consisting of the electric motor, transmission and power electronics featuring a new generation of silicon carbides. The power electronics unit is based on the one in the upcoming Mercedes-AMG Project ONE hypercar.

With output of around 150 kW, the super-efficient electric drivetrain (encompassing everything from battery to electric drive unit to wheels) provides the power and stamina. It is an electric drivetrain with 95% efficiency – that means up to 95% of the energy from the battery ends up at the wheels –compared to just 30% from even the most efficient combustion engine drivetrain or around 50% from an average (human) long-distance runner.

“One of the best ways to improve efficiency is to reduce losses,” explained Eva Greiner, chief engineer of the electric drive system at Mercedes-Benz. “We worked on every part of the system to reduce energy consumption and losses through system design, material selection, lubrication and heat management. And our fantastic simulation tools helped us find out quickly what works and what doesn’t.”

Aerodynamics have long been known to have a great influence on efficiency. Reducing the wind resistance of the car’s shape to as low as possible means the powertrain has to work less hard to achieve a given speed, reducing consumption or fuel or electricity. In the case of an EV, on a regular long-distance drive, almost two-thirds of its battery capacity may be used to ‘cut’ through the air ahead.

Through simulations and wind tunnel studies, the VISION EQXX has an ultra-sleek and slippery drag coefficient of 0.17 Cd. A huge amount of work went into integrating the painstaking passive and active aerodynamic features into the external form which retains the sensual purity of the Mercedes-Benz design language and the practicalities of a road car.

When it comes to lightweight engineering, the best on Earth is Mother Nature. No-one else comes close. Over millions of years, she has honed the finest examples of high-efficiency long-distance travellers – from the Monarch butterfly to the Arctic Tern.

With a considerably shorter timescale for the VISION EQXX, Mercedes-Benz engineers drew inspiration from her creations and pulled in some lateral-thinking external expertise to assist. The result is a weight-efficient design derived from engineering excellence paired with a sustainable combination of trash and Hollywood.

This intelligent use of sustainable advanced materials and methods inspired by nature is dubbed ‘bionic engineering’ and was facilitated by a digital process called bionic mesh design. Mercedes-Benz has a long history of applying bionic engineering techniques dating back to its “bionic car” concept study from 2005.

The VISION EQXX demonstrates that this is all within reach in a real-world vehicle that pushes the envelope on all fronts. It gives a clear insight into what premium efficiency for the electric and digital era looks like and feels like.

The all-electric future of Mercedes-Benz

New BMW i7 electric luxury flagship in final stages of testing, will launch later in 2022

It may seem like a fun job being a test-driver in a car company, driving prototypes of new models long before they are revealed to the world. While there may be some element of enjoyment at certain times, the work of a test-driver is largely planned and precisely run to verify performance as well as test many different parts and systems in a variety of conditions.

Every new vehicle must go through such demanding test programs and depending on the model, it might be in different parts of the world. The BMW i7, for example, is now entering its final phase of development work and is being tested in extreme road and weather conditions. It will be launched later this year, along with the new 7-Series.

During so-called hot-region testing on tracks and public roads all over the world, the development engineers primarily verify the performance and reliability of the electric motors, the all-wheel drive and the high-voltage battery when being exposed to maximum stress from high temperatures, unpaved roads, dust and large differences in altitude. They will travel over gravel tracks into deserts, into the mountains and on a whole series of highly dynamic routes, besides BMW’s own test courses.

The endurance test in the hot regions of various countries and continents serves in particular to test and safeguard all components of the electric drive system. The components of the fifth-generation BMW eDrive technology developed for the i7 demonstrate their unrestricted functionality – even under the most adverse conditions when being used continuously in extremely high outside temperatures, permanent sunlight and dry conditions.

Within a firmly defined test programme for the prototypes, loads are simulated that correspond to the challenges faced by a series-production vehicle during a complete product life-cycle. Supported by sensitive on-board measurement technology, experienced test engineers register every reaction of the electric motors, the high-voltage battery, drive control and the integrated cooling system as well as the charging technology and energy management to weather and road-related influences.

The testing programme, which covers tens of thousands of kilometres, includes long-distance and high-speed driving as well as stop-and-go traffic in high temperatures. In addition, test sections with particularly large differences in altitude were selected at the hot-region test sites. In this way the temperature behaviour of the electric motors and the torque control of the all-electric BMW xDrive can be analysed during a particularly dynamic and long-lasting uphill drive.

To further increase the load on the drive system, the test programme also includes mountain driving in trailer mode. At the same time, the high-voltage battery shows how it able to continuously deliver peak power to supply the e-motors. As an extreme scenario and a particular challenge for energy management and power electronics, the test also involves driving downhill with a high-voltage storage system that is already fully charged at the start and can therefore no longer absorb any recuperation energy.

The gruelling hot-region test procedure is also used to put the performance of the air-conditioning and other on-board electronics, as well as the temperature resistance of the materials used in the interior, to a particularly tough test. This is all to ensure that the world’s only purely electrically powered luxury sedan will delivers reliable performance in any situation, anywhere in the world.

BMW Group Malaysia moves into next phase of electrification with new BMW i model range

Toyota’s C+ Pod costs RM60,000 – is that low enough to attract Malaysians to buy an EV?

From this month onwards till the end of 2023, electric vehicles (EVs) imported to Malaysia will be exempted from all taxes and excise duties and even roadtax. This applies only to battery electric vehicles (BEVs) and not hybrids, for which the government provides other incentives for those which are assembled locally. Companies which decided to also assemble BEVs will get the full tax exemptions up till 2025.

To Malaysians, always frustrated by the high duty structure that makes cars expensive, the thought of duty-free cars gives them the idea that they can get cars much cheaper. However, BEVs are not cheap anywhere in the world if they are the type that are equivalent of the small and medium sedan or SUVs with combustion engines. They cost more and governments offer various incentives to reduce their prices for buyers so that adoption is faster.

If volumes can go up quickly, then production costs can come down and they can be sold more cheaply. This has happened in China where, since 2009, the government has offered subsidies to buyers of BEVs and the sales of such vehicles has grown to almost 5 million units a year. The volume is considered high enough and the subsidies will stop after this year.

Because of the sudden announcement only in October last year, plans to import vehicles have had to be put in place in the past few months and some companies have indicated they will be adding BEVs to their range later this year. Contrary to what those in the government may think, vehicles cannot be supplied right away. Orders have to be placed and factories have to slot in the orders and if demand is high from other markets, then it may take longer to get the vehicles. So many have indicated that they will start selling from the second half of this year, perhaps towards the last quarter.

*The Hyundai Kona Electric is the first BEV which has a price officially announced in Malaysia and it costs between RM150,000 to RM200,000 – duty-free.*

The prices indicated are not exactly low and many seem to be RM150,000 upwards – even with no taxes imposed. That sort of price level does not put BEVs within the reach of the masses which means that the volumes will not grow fast like in China and other markets. Not being able to reach a high volume will also slow the pace of infrastructure development as those who spend on it will see returns being slow.

As mentioned earlier, BEVs are expensive due to the technology which is still young compared to the technologies for combustion engines which have been developed and used for over 100 years. The ones that cost RM150,000 upwards are the ‘conventional’ type but in places like Japan and Europe, there are also smaller BEVs that cost much less though they can only seat two.

One such model is Toyota’s C⁺ Pod, an ultra-compact BEV which costs around RM60,000 in Japan. It went on sale in 2021 but only to corporate customers and government agencies. However, last month, Toyota announced that it would also make the C⁺ Pod available to the general public. The cars will be offered via lease contracts from Toyota dealerships

The C⁺ Pod is classified as a kei car, a category of minivehicles in Japan. It’s just 2.49 metres long and 1.29 metres wide; in comparison, the old Perodua Kancil was 3.4 metres long and 1.4 metres wide and could accommodate 4 persons. Although it has a light powertrain, the 9 kWh battery pack does add weight and makes the C⁺ Pod as heavy as a Kancil (690 kgs).

The small electric motor is positioned at the rear and can generate up to 9.2 kW with 56 Nm of torque. With the typical characteristic of an electric motor which delivers maximum torque from start-up, the little C⁺ Pod has good acceleration. However, it is clearly intended for city use and has a range claimed to be up to 150 kms.

The recharging infrastructure is well developed in Japan (almost 10,800 points nationwide) so owners can conveniently top-up the battery pack almost anywhere (though it will take 5 to`16 hours if the battery pack is completely empty).

Additionally, the C⁺ Pod is designed to be a mobile power supply system which can provide electricity in disaster areas. It’s an idea which developed after the big tsunami and earthquake in East Japan as there was urgent need for power supply by rescuers. There are sockets on the car to connect to and power can be supplied for up to about 10 hours, depending on conditions.

The cabin is like a car’s, with a simple layout that maximises use of the 1100 mm wide space, an important consideration since it is such as small vehicle. The exterior panels are made of plastic to keep weight down. But Toyota has ensured that safety standards (for this vehicle category) are met and there is a structure that efficiently disperses and absorbs impact energy across multiple components. This protects the occupants from serious injuries in the event of frontal, side or rear impacts. At the same time, the structure is also designed to reduce pedestrian injury.

To help the driver avoid accidents, there is also a Pre-collision Safety System which can detect other vehicles, pedestrians and cyclists. An Intelligent Clearance Sonar with Parking Support Brakes (Stationary Objects) is also included to help avoid collisions, or mitigate damage, with walls and other obstacles during low-speed operation.

The C⁺ Pod is just one of many small BEVs now on sale and they are popular in more developed countries like Japan where people appreciate having simple, personal transport. But will Malaysians accept such a small car priced at RM60,000, which is still almost double the price of a Saga? Incidentally, a Honda N-Box, the bestselling kei car in Japan, is priced between RM70,000 and RM80,000. As long as EVs do not have prices at the same level as the cheapest models of the two national brands, it will be hard for the country to move towards electrification.

Toyota to step up investment and development of fully electric vehicles during this decade

China to end subsidies for New Energy Vehicles after 2022

There were electric vehicles 100 years ago; in fact, even Henry Ford’s wife, Clara, drove and electrically-powered car because it was easy to start and had no transmission. However, battery technology at that time was not advanced and poor performance made electric cars unappealing, allowing cars with internal combustion engines to grow and then dominate the planet. With poor interest in electric cars, the manufacturers stopped developing them and would not consider them again till the 21^st century.

During the 100 years, many technological advances have been made and in the past 20 years especially, battery technology – an important element for electric vehicles (EVs) – has advanced greatly. The incentive to accelerate technological development has been the tightening of emission regulations, especially in the more developed nations, which has forced carmakers to start switching to emission-free powertrains. There is urgency as well due to climate change, with exhaust emissions of motor vehicles being identified as one of the causes.

The technology and manufacturing processes for the internal combustion engine (ICE) have been developed over more than 100 years so production costs have stabilized and as volumes grew, economies of scale kept pushing the costs down. EV technology is relatively young and the volume of EVs has not reached a point where economies of scale have fully kicked in. As such, the technologies – which are still evolving and advancing – are still expensive and EVs equivalent to ICE vehicles are still more expensive.

In order for EVs to be adopted by more people, the auto industry expects governments to help. Obviously, funding cannot be provided directly but the prices to buyers can be offset by subsidies. The lowering of retail prices can then attract motorists to consider them, while other elements like infrastructure and performance continue to get better.

Many countries have subsidies for EV buyers and the nature of the subsidy varies. Typically, there is a fixed sum provided based on the price although in Malaysia, from this year, the government has decided to exempt battery electric vehicles (BEVs) from duties and other taxes and even the annual roadtax will not be charged. It’s a bold move but it does not necessarily bring prices down below RM100,000 so a large segment of the population will still not find it easy to buy one. And there is no point using the argument of ‘saving the planet’ because many Malaysians today have to save themselves and their families from financial difficulties, so they certainly won’t care to pay more for their car.

China, as the world’s largest car market, has had an incentive program since 2009 when it introduced subsidies for New Energy Vehicles (NEVs), ie BEVs, plug-in hybrids (PHEVs) and fuel cell vehicles (FCEVs). The NEV program actually began in the 1980s but the incentive policy only began in 2009, with nationwide adoption from 2013. To qualify for subsidies, the vehicles must meet minimum technical and performance requirements, and the size of the subsidy is indexed to a variety of vehicle specifications and utility parameters. Every few years, the qualification criteria have been tightened, forcing manufacturers to push their technology further.

*As qualification criteria for subsidies tightened during the past decade, the manufacturers had to keep improving their EV technologies.*

By the end of 2020, the NEV push had resulted in 4.92 million NEVs being put on China’s roads, or 1.75% of the vehicle population. The number almost meets the 5 million target set in 2013 and having reached this level, the government now believes that acceptance has been achieved and NEVs are in the mainstream of the car market. This year NEVs are expected to account for 18% of all vehicle sales in China (13% greater than in 2019) and add another 5 million NEVs according to industry forecasts.

*With this year being the final year that EVs will be subsidised, there should be increased interest and higher sales in China.*

And with that target achieved, it has now decided that subsidies can be phased out completely. In fact, in April 2020, there was already an indication of this when it was announced that subsidies would be reduced by 20% in 2021. This year, the cut will be 30%, after which there will be no more subsidies provided from January 1, 2023.

The subsidies have typically applied to vehicles costing less than RMB300,000 (about RM197,130). A typical subsidy has been around RMB18,000 (about RM11,800), and in 2022, it will fall to around RMB14,400 (about RM9,500).

*Tesla Model 3 was among the best-selling NEVs in China last year.*

The domestic carmakers have already reached large volumes that allow them to have economies of scale. BYD, an early EV manufacturer, was already doing over 753,000 EVs in 2019, second after world leader Tesla which sold 900,000 EVs.
