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

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

While Toyota has expressed a view that suggests it will not stop producing internal combustion engines so quickly – to provide customers with greater choice and not leave any customer behind – it is no less committed to electrification of its products in the quest to achieve carbon neutrality. As a pioneer in hybrid electric vehicle (HEV) technology, having introduced the first mass-produced car with a hybrid powertrain in the late 1990s, the carmaker has naturally been promoting the technology which also contributes to reducing toxic exhaust emissions and fuel consumption.

Long history of EV developments
However, in the longer term, fully electric vehicles are going to become mainstream products, beginning with battery electric vehicles (BEVs) and progressing to fuel cell electric vehicles (FCEVs). In fact, the company has an EV development division since 1992 and an early production EV that went on sale in 1996 was the RAV4 EV, Today, besides a wide range of HEVs, Toyota already offers BEVs and even FCEVs, the latter now in the second generation with the Mirai.

*Toyota sold (in limited numbers) a fully electric model – the RAV4 EV – in 1996 and today, it has even begun selling electric vehicles powered by hydrogen fuel cells like the Mirai (below).*

The crucial technology
Battery technology is obviously crucial for every carmaker and Toyota will invest greatly in R&D for this area as well as in the supply system. The carmaker has had a subsidiary fully involved in battery development and manufacturing and has aimed to bring about cost reduction of at least 50% per vehicle during this decade. At the same time, safety, longer service life and high quality will be advanced.

*Battery technology is a crucial area for electric vehicles and Toyota will be spending heavily to develop more advanced technologies as well as push battery cost down.*

“Over the past 26 years, we have invested nearly 1 trillion yen and produced more than 19 million batteries. We believe that our accumulated experience is an asset that gives us a competitive edge. Going forward, we will increase our new investment in batteries from the 1.5 trillion yen announced in September to 2 trillion yen, aiming to realize even more-advanced, high-quality, and affordable batteries,” said Akio Toyoda, President of Toyota Motor Corporation, at a press conference in Tokyo this afternoon.

*1 trillion yen = approximately RM37.2 billion*

*The bZ4x is the first of the new range of BEVs and production is now underway with sales set to begin in 2022.*

*Toyota’s range of BEVs by the end of the decade will look something like this.*

As long as Akio Toyoda is leading Toyota, we will still get sportscars – even if they run on electricity instead of petrol (although the company is now exploring use of hydrogen as a fuel in combustion engines).

Sales volume of BEVs raised
Besides outlining the company’s BEV strategies, Mr. Toyoda also revealed 16 Toyota and Lexus BEV models that it is readying for market launch, starting with the Toyota bZ4X which has already had been shown in production form and will begin sales in 2022. By 2030, the company is going to roll out 30 BEV models and is anticipating sales of 3.5 million BEVs globally. This is an increase of 75% on the previous annual sales projection of 2 million BEVs mentioned in May this year. The Lexus brand aims to have BEVs, which will be in every segment, account for 100% of the total sales in Europe, North America, and China by 2030.

*Lexus will develop a full range of electrically-powered models, including sportscars that may look like the one below.*

*Lexus RZ BEV prototype during development testing. First teaser image of production model shown below. It will go on sale in 2022.*

In this diversified and uncharted era, it is important to flexibly change the type and quantity of products produced while keeping an eye on market trends. At the same time, energy plays a critical role in achieving carbon neutrality. For this reason, Toyota wants to provide a diversified range of carbon-neutral options to meet whatever might be the needs and situations in every country and region.

*Just like today, Toyota will have something for every segment of the market to suit different requirements and conditions.*

Markets and customers decide
“It is not us but local markets and our customers who decide which options to choose. As for why we try to keep so many options, in terms of business management, one might think it would be more efficient to focus on fewer choices. However, we believe that quickly adapting to changes in the future is more important than trying to predict the future, which is uncertain. That is why we want to keep options available for our customers until the right path is clear,” said Mr. Toyoda.

Toyota: “No customer is left behind” in quest for carbon neutrality

GM’s Factory ZERO starts production of only electric vehicles

Roger Smith, the former General Motors Chairman and CEO from 1981 to 1990, introduced huge amounts of technology into the company in the 1980s to gain what he believed would be an advantage in vehicle production. He fantasized about a ‘factory of the future’ which would work 24 hours non-stop without needing lights as there would be no human workers. Everything would be automated so no worries about unions and strikes.

But total automation and high-tech have not proven to be the way to become an efficient and productive carmaker. In later years, after Smith had retired and GM formed a joint-venture with Toyota to operate a factory in California making cars of both brands, it would be discovered that the Japanese ‘secret weapon’ was not some advanced manufacturing equipment but something more human like training and having the right culture.

Three decades later, the new General Motors has created another high-tech factory though ‘future’ is no longer mentioned. It is actually the old Detroit-Hamtramck assembly plant which received a massive US$2.2 billion investment to be fully renovated for building a new generation of battery electric vehicles (BEVs).

General Motors Factory ZERO — *The signboard on the 110-year old General Motors Detroit-Hamtramck factory being taken down in September 2020 as work was underway to renovate it into Factory ZERO to build only electric vehicles.*

The various meanings of ZERO
Recently opened, the factory is known as Factory ZERO and while ‘zero’ is today associated with ‘zero emissions’ from vehicles, the name also reflects the significant role the facility plays in advancing GM’s vision of a world with zero crashes and zero congestion. It will make models such as the GMC HUMMER EV Pickup and HUMMER EV SUV, Chevrolet Silverado EV and Cruise Origin, an all-electric, self-driving, shared vehicle.

All Factory ZERO EVs will be built on GM’s Ultium Platform which is the core technology for the company’s EV product strategy. The Ultium Platform encompasses a common vehicle architecture and propulsion components like battery cells, modules, packs, drive units, EV motors and integrated power electronics, and is fundamental at plants where EVs are produced.

*GM’s Ultium platform which will be used for the EV models of its different brands.*

*The GMC HUMMER EV SUV is one of the models to be built at Factory ZERO and will go on sale in 2023.*

Through the Ultium Platform, GM can realize a strategic value chain shift across its network of vehicle assembly plants as the company is able to commonize and streamline machinery, tooling and assembly processes. This gives the company flexibility which huge corporations sometimes lose, and enables lower capital investments and greater efficiencies as additional assembly plant transformations occur.

GM’s competitive advantage
GM retooled Factory ZERO for BEV production for two-thirds the capital required to build a greenfield (brand new) plant, making the facility a model for future GM facility renovations. Some of the approaches taken during construction include reuse or recycling of almost every material that came out of the old facility during conversion. This included crushed concrete from the floor, which was repurposed for temporary roads around the facility. Storm water will be recycled and of course, solar power will contribute to the electrical needs.

As the company continues its transition into an all-electric future, GM will avoid up to US$15 billion in capital costs by 2030 through the renovation of existing manufacturing facilities versus ground-up construction. The figure grows to US$20 billion to US$30 billion at 100% transition of all manufacturing facilities to support EV production. That capital can be redeployed more strategically for additional customer-facing products, services and technologies.

“To meet our ambitious EV transition, GM’s North American EV vehicle assembly capacity will reach 20% by 2025, and then 50% by 2030,” said Gerald Johnson, GM’s Executive Vice-President of Global Manufacturing and Sustainability.

Shortened launch time
Using virtual tools and working in parallel with production engineering teams, GM cut the manufacturing launch time in half – from two years to less than one – also gaining a competitive advantage. By comparison, a brand new factory, with planning and construction, could take up to 4 years from site selection to vehicle production.

Along with the capital advantages, GM’s commitment to renovating its existing network of manufacturing facilities during the EV transition also saves time. An accelerated launch and production start allow the company to get new-generation EVs to customers sooner. The first vehicles from Factory ZERO will be delivered to customers by the end of this year.

GM estimates that 80% of the assembly process for an EV is the same as that for conventional vehicles. This is another driver of speed for GM. The company has refined and perfected its own standardized manufacturing processes over many decades, and will launch its expanding portfolio of BEVs faster, with superior quality and a lower cost.

People still matter in manufacturing
Roger Smith imagined a factory with robots and almost no human workers but Factory ZERO, when fully operational, will employ more than 2,200 people. “Our people are GM’s true competitive advantage — an advantage you simply can’t buy or quickly build,” said Johnson, echoing what Japanese carmakers have often said.

As a BEV factory, Factory ZERO plays a direct role in GM’s commitment to eliminate tailpipe emissions from new light-duty vehicles by 2035 and become carbon-neutral in its global products and operations by 2040. The company has already made a commitment to invest US$35 billion in electric and autonomous vehicles, with plans to introduce more than 30 BEV models by 2025.

Toyota reveals details of production bZ4X EV to be launched in mid-2022 (w/VIDEO)

After pioneering the mass production of hybrid electric vehicles (HEVs) in the late 1990s, Toyota is starting its big push into full electrification with a more extensive line-up of battery electric vehicles (BEVs). Until now, it has focussed on HEVs although it has had a small range of BEVs but now the carmaker is making the big leap towards larger models and aiming for higher numbers.

The first of the 7-model bZ range (by 2025) was previewed at Auto Shanghai in April this year in the form of the Toyota bZ4X concept. To be made in China and Japan, worldwide sales of the production version of the new BEV is expected to start by the middle of 2022.

Details of the new model, which will be a SUV, released today show that the production model is pretty much like the concept car. This is not surprising as Japanese carmakers have not wasted time and money on making too many fancy concepts to wow people but which never get built. They have instead previewed near-production concept cars as a final step to get last-minute feedback on designs and features.

e-TNGA architecture
The new model, to also be known as the bZ4X, sits on a BEV-dedicated platform (first for Toyota) based on e-TNGA philosophy. TNGA stands for Toyota New Generation Architecture, a flexible architecture used for all of the latest models. The one for the bZ4X has been jointly developed with Subaru Corporation which will also have its own BEV to be called the Solterra.

The platform has the advantages that TNGA provides such as a low centre of gravity and high rigidity, all of which will contribute to better driving dynamics and even good off-road performance since this is to be a SUV.

FWD or AWD
The powertrain is straightforward with one or two motors, the latter for the all-wheel drive version. System output is 150 kW for the front-wheel drive version and 160 kW for the AWD version. The E-axle integrates the electric motor, transaxle and inverter while the Electricity Supply Unit consolidates charging and power distribution functions.

Battery performance and safety
As with all BEVs, the key points that motorists will want to know are the performance of the battery pack. The 71.4 kWh lithium-ion battery pack (made by an affiliated company) is expected to provide a cruising range of about 500 kms’, even in cold regions.

Compatible with high-output chargers worldwide, an 80% charge is said to be possible within 30 minutes. Besides the usual methods of recharging, there is an optional solar panel on the roof that can also convert sunshine to electricity for the battery pack.

It is also targeting a top-class battery capacity retention ratio (90% after 10 years of use or 240,000 kms). More attention has been given to preventing battery failure by strengthening measures to prevent and detect abnormal conditions (eg overheating). There are also new technologies with a multiple monitoring system that ensures safety and security in case of emergency.

Toyota’s subsidiaries have been developing and making batteries for many years and have gained a lot of knowledge. They have now developed a production process that eliminates contamination, which is a cause of abnormal heating. There is also a high-resistance coolant which prevents fire from short circuits even if there is leakage of the battery’s liquid coolant.

Safety is not forgotten and this is new territory for carmakers. While the basic structure has similarities to combustion vehicles, the high-voltage systems require specific protection. To ensure a high degree of battery pack safety, the Toyota Safety Sense active safety package is used and the body structure has been adapted to withstand collision from any direction. The battery pack itself is also designed in a way that contributes to ensuring protective performance in a collision.

Toyota has also developed more proactive initiatives with regard to the end-of-life scenario for battery packs. The company has a Battery 3R – Rebuild, Reuse, Recycle – approach which will ensure a worldwide top-class battery capacity retention ratio. It proactively undertakes battery rebuild (inspection and reassembly) and reuse and promotes initiatives for battery recycling.

RAV4 size but more spacious
The bZ4X has an overall length of 4690 mm and overall width of 1860 mm, which is about the same size as a RAV4 but it is around 100 kgs lighter. Due to the entirely different powertrain and layout of components, the wheelbase is significantly longer than the RAV4’s – 2850 mm versus 2690 mm. This naturally means a more spacious cabin which is also extra wide. Toyota says that the tandem distance is equivalent to that of a sedan like a Camry.

As the pictures show, the cockpit area is futuristic with the meters positioned to be visible through the upper part of the steering wheel. This is the first time a Toyota vehicle has such an arrangement and it is emphasizes ease of viewing by reducing eye movement and enabling a distance point of focus.

This is the second time that Toyota’s interior designers have given more thought to viewing the meters. When the first Prius hybrid was designed, the meter display was located at the centre of the dashboard instead of its traditional place ahead of the steering wheel. This was to improve eye focus (especially for older drivers) by not having a short viewing distance to the meter and a longer one to see the road ahead. Positioning the display further away meant that the driver’s focus would be further away most of the time, reducing changes and improving safety.

2022 Toyota bZ4X EV — *Unique steering wheel will be initially available only on cars sold in China. Other markets will have a conventional circular steering wheel (below) which will be changed progressively.*

The modularized driving controls including a steering column with a wing-shape. The one-motion grip combining steer-by-wire system and uniquely shaped steering wheel will be first offered in cars sold in China and progressively added to those in other markets. Before then, the other markets will have a conventional circular steering wheel.

Different regions, different approaches
Clearly, Toyota intends to quickly move to the forefront of the EV market as it did with hybrid electric vehicles. It has different strategies for different markets and regions, depending on the supply of electricity and the recharging network. For Malaysia, the decision has been made that the first phase of electrification will be to assemble hybrid electric vehicles locally.

While the latest news today of full tax exemption for EVs does make it possible for models like the bZ4X to be sold, it is likely that Toyota’s production and marketing plans for the next few years have already been set. The major markets will already have given big numbers that will probably take most of the output from plants in China and Japan, so a smaller market like Malaysia may have to wait till later. At best, we may a small number of units imported more to gauge market response while UMW Toyota Motor focusses on growing HEV sales for which a RM270 million investment has already been made.

Toyota: “No customer is left behind” in quest for carbon neutrality

Tevva Truck to help immediate commercial vehicle industry need to electrify

Commercial vehicles (CVs), like passenger cars, will also have to follow the electrification route during this decade. This is especially so in Europe where there is a commitment by industries and governments to a target of net zero emissions by 2050, alongside a proposed ban on the sale of all polluting vehicles by 2035. With less than 15 years to go, there is now increased activity in developing electrically-powered trucks and there are already some in the market from leading manufacturers.

With demand for CVs therefore growing, there are other players coming into the market as well. One of them is Tevva Motors Limited, a UK-based company that describes itself as being ‘at the forefront of the design and manufacturing of zero emissions commercial vehicles’. The team at Tevva is led by Ken Scott, formerly Engineering Director at both Bentley and Alexander Dennis, with styling handled by Dale Grewer, former Chief Designer at Jaguar Land Rover.

Fully built in Britain from 2022
The company recently unveiled its new truck – simply called the Tevva Truck – which will be fully built in Britain on a high-volume basis from mid-2022. It is the culmination of 7 years of engineering development and the learning gathered from over 320,000 kms of in-fleet trials. Tevva expects to be building 3,000 trucks a month from 2023.

The 7.5-tonne (GVW) electric truck is the first of a series of electrically-powered vehicles that will extend to 19.5 tonnes for the UK, European, and Middle Eastern markets. Using a rechargeable battery pack, the claimed range is 250 kms while having patented range extender technology (REX) now upgraded to use hydrogen fuel cells, can provide a range of up to 500 kms.

Tevva says its new truck offers a best-in-class combination of capability and cost efficiency from a zero emissions medium-duty truck, while offering the ruggedness and resilience of traditional trucks.

Ownership cost comparable to diesel truck
Range is obviously a concern to fleet managers who want the furthest distance at the lowest cost. The total cost of ownership is said to be comparable to a diesel truck; parity is achieved at approximately 3,000 kms or when 500 litres of diesel are consumed per month. The REX solution using compact hydrogen fuel cells can recharge the battery on the move, allowing longer duty cycles and transporting heavier loads even further.

Future technical developments already being tested will enable the Tevva Truck to be fully charged in just one hour – facilitating double shift operations, to help reduce the total cost of ownership. The time spent recharging will also be important to operators and as technology continues to advance, the times should keep shortening. Eventually, the driver won’t have time to have a cup of coffee and a meal at the recharging station.

Meeting the immediate industry need
The Tevva Truck will help the immediate industry need to electrify with transformative battery electric vehicles for the real world. “Technology is transforming the commercial vehicle sector at pace, making it safer, greener, and entirely more efficient. But meaningful change is a gradual process, it must happen one step at a time, even if those changes are needed in fast succession. The Tevva Truck provides a natural transition into electrification for fleet managers, providing total peace of mind and a compelling total cost of ownership proposition, with no compromise on range and reliability and minimised compromise on payload,” said Asher Bennett, Founder and CEO of Tevva.

Lotus reveals all-new lightweight structures for future electric vehicles

Just last month, Lotus confirmed it would be launching a new electric sportscar in 2026 – designated Type 135 – as part of a range of electrically-powered performance cars to be manufactured in the UK. The sportscar will have innovative new lightweight chassis technology developed through Project LEVA (Lightweight Electric Vehicle Architecture), which the carmaker mentioned last October.

Project LEVA is a research programme that’s accelerating the development of all-new lightweight structures for next-generation battery electric vehicles. The structure developed through Project LEVA will be integrated into the company’s new architecture for electric sportscars.

This structure represents the ‘blueprint’ for the next generation of electric sportscars, for future Lotus products, and for the Lotus Engineering consultancy to commercialise. One example of its innovation is that the rear structure is 37% lighter than it is on the Lotus Emira V6. It is fully adaptable to provide a platform for a range of vehicle types with variable layouts, wheelbase lengths, battery sizes and configurations.

All three layouts feature a common lightweight die-cast rear subframe with multiple interchangeable components. This is the Project LEVA innovation: it means a single vehicle architecture can accommodate two different types of battery configurations.

The ‘Chest’ layout is where the modules are stacked vertically behind the two seats. A chest layout is a ‘mid-mounted power pack’, ideal for sportscar/hypercar vehicle types where a low overall ride height and low centre of gravity are required, eg Lotus Evija pure electric hypercar.

The ‘Slab’ layout, where the modules are integrated horizontally under the cabin, is most suitable for vehicles where a higher ride height and a taller overall profile is required. It is often referred to as a ‘skateboard power pack’ layout.

The innovative new subframe features cylindrical battery cells for high energy density, with the option of a single or twin electronic drive unit (EDU) to support. Cold cure, spot bonding and advanced weld processes mean reduced environmental impact during assembly.

This unique degree of flexibility and modularity in wheelbase and propulsion solutions will be the genesis for a wide variety of electric vehicle applications. These could be for the Lotus electric sportscar – scheduled for launch in 2026 – as well as for other clients through Lotus Engineering.

“Project LEVA is as revolutionary now as the Elise architecture was in 1996. In true Lotus spirit, significant weight-savings have been achieved throughout, with a focus on ultimate performance, efficiency and safety being engineered into the structure from the outset,” said Richard Rackham, Head of Vehicle Concepts at Lotus. He leads Project LEVA and is best known for his revolutionary work on development of the extruded aluminium Lotus Elise architecture 25 years ago.

Lotus Vision80 plan to transform company on journey of global expansion

Toyota: “No customer is left behind” in quest for carbon neutrality

Carbon dioxide (CO₂) is known to be one of the major causes of climate change, causing global warming. However, it is a by-product of modern industrial processes and unavoidable. To address the issue of rising carbon dioxide gas in the atmosphere, carmakers (as well as manufacturers in other industries) aim to become ‘carbon-neutral’ in the near future. This means that their processes, products and activities, while generating carbon dioxide, will be balanced with strategies that offset the CO2 generation to achieve net-zero emissions.

The approach most commonly being adopted, at least as far as the products are concerned, is to stop making and selling motor vehicles with internal combustion engines (ICE) that have been major contributors of carbon dioxide and other undesirable gases in the environment. Some have announced a time-frame for this approach, after which they will not sell models with ICE or, in some cases, models with only ICE (meaning they will still have hybrids). These companies are investing heavily in electric vehicles (EVs), powered by battery packs or fuel cells.

Toyota does not plan to completely stop selling models with petrol or diesel engines in the near-term but, at that same time, it already has a growing line of battery electric vehicles (below) for markets that want such vehicles.

Committed to carbon neutrality by 2050
Toyota is one of the companies firmly committed to carbon neutrality by 2050. However, the company’s strategy does not entirely focus on electrification of its products to the extent that future models will no longer be powered by ICE in the near-term. In time, it may decrease the amount of development of totally new ICE powertrains as EV acceptance in the market rises.

The thing is, advanced countries have developed the infrastructure to support EVs, so consumers are assured that owning an EV is not going to be inconvenient. Apart from widespread availability of public recharging stations, some countries also offer incentives to those who buy an EV. As a result, some countries in Europe already see EVs accounting for a large proportion of new vehicle sales.

*For more advanced markets with the necessary infrastructure to support fuel cell vehicles, Toyota already has the second generation of its Mirai FCEV available.*

Different pace in different regions
However, in other countries and regions, the transition to EVs may be at a different pace. For example, Indonesia, Thailand and Singapore already have clearly-defined plans to ‘go electric’ but Malaysia does not (although recent news suggests that some incentives may soon be announced). Countries in Africa might also be slower to stop allowing ICE vehicles due to their economies and other factors.

Toyota wants to make sure that ‘no customer is left behind’ and for this reason, it will use multiple technology solutions in its quest to achieve carbon neutrality, developing advanced electric vehicles as well as continue to make ICE as clean as possible. The carmaker’s view is that companies and societies should work together with all available technologies to achieve the best and fastest results towards carbon neutrality – using whichever solutions and infrastructures suit their local needs best.

7^th Environmental Action Plan
Toyota is currently in its 7^th Environmental Action Plan which runs until 2025. The targets for this plan include reduction of CO2 emissions by 30% or more (on average) compared to 2010 levels, and boost cumulative sales of electrified vehicles to 30 million or more. All models in the Toyota and Lexus ranges worldwide are to be available with either full electric or hybrid powertrains by around 2025.

At the same time, CO₂ emissions are to be reduced by 18% or more throughout the entire vehicle life cycle (including manufacturing and driving) compared to 2013 levels.

“The goal is carbon neutrality. Promoting Battery Electric Vehicle sales or banning gasoline cars is not in any way the goal. It is a must that cars already on the road be made carbon-neutral. Rather than narrowing the way out by placing importance on the creation of regulations focused only on new cars and internal combustion engines, it is necessary to expand the paths to carbon neutrality by including all approaches,” said Toyota President, Akio Toyoda, in his capacity as President of the Japan Automobile Manufacturers Association (JAMA).

Toyota is known to be cautious in venturing into new segments, watching competition start first and seeing the shortcomings – and then coming in with products that are often better. With electrification, the company has had dominance in the hybrid segment but seemed to be slow to get into full electrification. This is not to say that it was not developing models, but commercialising them was something that was slower.

Now, however, the company is starting its big push into full electrification, which is part of its commitment to contribute to reducing CO₂ emissions. To achieve this. Toyota is establishing a full line-up of electrified vehicles which will reach around 70 by 2025; at least 15 models will be launched by 2025.

Starting with SUV BEV
At Auto Shanghai, which is on this week, the Japanese carmaker has announced its new BEV (Battery Electric Vehicle) series to start off and is displaying a concept car, the Toyota bZ4X, as a preview of the first model of this series. To be made in China and Japan, worldwide sales of the production version of the new SUV BEV is expected to start by the middle of 2022.

Development of the bZ series (‘bZ’ stands for ‘beyond Zero’) is based on BEV-dedicated platforms that can be used with multiple variations in terms of size and design. Since it is difficult for Toyota to prepare such a wide range of choices by itself, it is jointly developing the series with partners who have the appropriate expertise in various fields. In the case of the bZ4X, Subaru is involved as a partner.

e-TNGA platform
The new vehicle will adopt the e-TNGA BEV-dedicated platform that was jointly developed by the two companies. It takes advantage of the strength of Toyota, which boasts expertise in vehicle electrification, and Subaru, which possesses AWD technologies. The bZ4X combines a long wheelbase with a short overhang which allows both a distinctive design and interior space comparable to a D-segment sedan.

The bZ series BEVs will have a human-centered approach aimed at widespread use in regions such as China, the USA and Europe, where there is significant demand for BEVs, and where there is a large supply of renewable electricity.

A uniquely shaped steering wheel eliminates the need to change grip when steering, and also contributes to a spacious interior. The vehicle will have a steer-by-wire system that provides a smooth driving feel aligned with the driver’s intentions. The low position of the instrument panel and the location of the meters above the steering wheel serve not only to enhance the vehicle’s sense of space, but also improve visibility and contribute to safe and secure driving.

The bZ4X has a new AWD system jointly developed by Toyota and Subaru. In addition to the use of regenerative energy systems, the vehicle also adopts a solar recharging system that recharges the battery while stationary.

Kia to move away from traditional manufacturing-driven business model

Earlier this month, Kia unveiled its new corporate logo with the new brand slogan of ‘Movement that inspires’. This slogan replaces ‘The Power to Surprise’ which has been in use since 2005 (although the US also had a new slogan in 2019 – ‘Give It Everything’). With the new slogan also comes a new strategy which the Korean carmaker will probably use throughout this decade, or into the next one.

Signalling the brand breaking away from its traditional manufacturing-driven business model, the corporate name will now be Kia Corporation, instead of Kia Motors Corporation, though the public has usually used just ‘Kia‘ anyway.

Beyond vehicle manufacturing
The strategy will see the company go beyond vehicle manufacturing to create sustainable mobility solutions for customers. According to Ho Sung Song, President & CEO of Kia Corporation, the company’s vision is to create sustainable mobility solutions for consumers, communities, and societies globally.

“At Kia, we believe that transportation, mobility, and movement represent a human right. Today, we start putting the company vision into action with the launch of our new brand purpose and strategy for the future,” he said.

New brand purpose
Kia’s new brand purpose emphasises that movement is at the genesis of human development. Movement enables people to see new places, to meet new people, and to have new experiences. This connection is the essence of Kia’s new brand – to enable human progress by providing innovative in-car spaces, exciting new products, and meaningful, convenient services that inspire customers and free up time for the activities that they enjoy the most.

Kia has been in the ‘movement’ industry for more than 75 years, starting with Korea’s first domestic bicycles and then manufacturing motorcycles and delivery trucks. As in past decades, it will meet changing customer expectations about how they move, and how their movement impacts the world around them.

The broader vision for sustainable mobility
Reflecting the brand’s broader vision for mobility, Kia is expanding its business to encompass EVs, mobility solutions and services, purpose-built vehicles, and more. Alongside these efforts, Kia will simultaneously promote more sustainable production through the usage of clean energy and recyclable materials.

The company is focused on popularising battery electric vehicles (BEVs) and plans to reinforce its global product line-up with the introduction of 7 new dedicated BEVs within the next 6 years. These new models will be in several segments, each incorporating advanced technologies for long-range driving and high-speed charging from Hyundai Motor Group’s new Electric-Global Modular Platform (E-GMP).

Purpose-Built Vehicles
Kia is also developing a range of new Purpose-Built Vehicles (PBVs) for corporate customers. These specialised vehicles will be based on flexible ‘skateboard’ platforms, with modular bodies designed to meet the specific mobility needs of a broad range of corporate and fleet customers. Partnerships with the likes of Canoo and Arrival will mean Kia PBVs can offer different bodies mounted on top of an integrated modular ‘skateboard’ platform, tailored to users’ functional requirements.

Demand for PBVs is expected to grow 5-fold by 2030 due to rapid and sustained growth in e-commerce and car-sharing services. Bespoke Kia PBVs will be tailored to meet the needs of corporate and fleet customers. For instance, these could include car-sharing vehicles, low-floor logistics vehicles, and delivery vehicles.

The change in the company’s corporate name also means transforming the organisation’s working culture. “Changing our corporate name and logo is not only a cosmetic improvement. It represents us expanding our horizons and establishing new and emerging businesses that meet and exceed the diverse needs of our customers worldwide. More importantly, it also means adapting our working culture, enabling the creativity of all our employees and establishing an inspiring work environment,” President Song explained.

First dedicated BEV coming soon
With its growing range of BEVs, Kia is targeting a 6.6% share of the global BEV market by 2025, and global annual sales of 500,000 BEVs by 2026. The first of Kia’s next-generation BEVs will be revealed in the first quarter of 2021, embodying Kia’s shifting focus towards electrification.

Based on new E-GMP technology, this dedicated BEV will boast a crossover-inspired design, while offering an electric driving range of over 500 kms and a high-speed charging time of under 20 minutes. This will also be the first global model to bear Kia’s new logo.

Lexus reveals DIRECT4 technology for future hybrids and EVs

The transition to electrified vehicles has been taking place across the auto industry since this century began although for the premium and luxury brands, it may appear slower. Perhaps these brands in the upper stratosphere of the market want to make sure that when they do go all the way to fully electrically powered cars, their customers will still enjoy the same comforts and performance.

Lexus, Toyota premium luxury brand, has been working towards this to ensure that the ‘Lexus Driving Signature’ will be present in future hybrid and battery electric vehicles (BEVs). While it obviously shares resources with Toyota, it also has its own technological advancements and one of them now being revealed is DIRECT4, which will be a core Lexus Electrified technology.

DIRECT4 is a new system which can provide instant electric control to all four wheels to transform dynamic performance, working instantaneously according to driving conditions and driver intentions It is said to also give greater design freedom to reimagine Lexus’ signature design.

First glimpse of new BEV design concept
At the 2019 Tokyo Motorshow, to illustrate its new global electrification strategy, Lexus displayed the futuristic LF-30 concept car (pictured below). The new strategy, called ‘Lexus Electrified’ targets a fundamental leap in vehicle performance, handling, control and driver enjoyment.

Lexus Electrified technology supports this vision with DIRECT4 for its next generation of battery electric and hybrid electric vehicles. DIRECT4 precisely controls the delivery of drive torque from front and rear electric motors and braking force to all four wheels. By automatically adjusting the balance of front and rear-wheel drive, the system adapts the driving conditions to the driver’s intentions, changing the driving feel and giving the car the best driving posture.

The system uses a front and rear e-axle, each featuring a high-torque electric motor and transaxle, focusing on optimum drive force distribution. As the motor is directly connected to the wheels by a single driveshaft, it operates without delay.

Its operation is intuitive and highly responsive, giving the driver a genuine sense of being fully connected with the vehicle. Moreover, it provides an ideal balance of predictability and excitement, with powerful, linear acceleration and exhilarating cornering. At the same time, the system is engineered for quietness and comfort, which will always be expected by those who travel in a Lexus.

Supporting the Lexus Driving Signature
In developing DIRECT4, Lexus has been able to draw on its experience in electrified vehicle technologies. This expertise supports the development of ‘Lexus Driving Signature’ that will define the dynamic performance of Lexus’ next-generation vehicles.

According to Chief Designer Koichi Suga, electrification technologies will impact on vehicle design as well as performance, for example with no requirement to provide front cooling for an engine and radiator. This will present new opportunities to express technological advances in the car’s 3-dimensional form.
