Additional refinement for Lexus UX with latest enhancements and upgrades

After introducing the first premium luxury SUV in 1997, Lexus broadened its crossover line-up to cover every segment and as the industry moved towards smaller body sizes, Lexus followed likewise with new models. Its smallest is the UX, introduced in 2018, with a cumulative total of approximately 240,000 units sold globally.

The UX has been doing battle in one of the most competitive segments of the market and this year, it gets upgrades to keep it on par with rivals. Besides enhancements in the multimedia system, the new UX also has improved safety technology and better driving dynamics.

Under the skin, structural rigidity has been improved by adding 20 spot-welding points around the bodywork. The increased rigidity, besides giving additional passive protection, helps to enhance handling. At the same time, the electric power steering system and shock absorbers pf the suspension have been retuned accordingly to help provide a smoother transition between braking, steering and acceleration through bends and on a variety of road surfaces. It is this linear vehicle operation faithful to the driver’s input that defines the Lexus Driving Signature.

The Lexus Safety System+ 2.5 is a suite of active systems that lighten the driving burden on the driver and more importantly, help avoid accidents (or minimise the damaging effects). The single-lens camera on the windscreen and millimetre-wave radar in the grille have been improved to more effectively scan the road ahead. This enables expansion of the response range of the Pre-Collision System which can detect bicyclists and pedestrians (even in low-light conditions) and, at intersections, detect oncoming vehicles before turns. The system also detects pedestrians crossing the street from the direction toward which the vehicle was traveling before it started to make a right or left turn.

Also featured are functions such as Emergency Steering Assist, which assists steering within the vehicle’s lane as cued by the driver. The lane-recognition functions of Lane Tracing Assist have been improved through the application of AI technologies that expand the assist range, resulting in smoother and more-continuous steering assist.

Dynamic Radar Adaptive Cruise Control is a very useful autonomous system that ensures a safe gap[ from the vehicle in front and it functions at all speeds. To enhance its operation on highways with curves, the curve speed-control function decelerates the vehicle in advance according to the size of an approaching curve.

Most Lexus models have the Panoramic View Monitor nowadays so the driver can see all round the car with imagery captured by small cameras on the body. A new and advanced feature is an underbody transparent display which combines images of road surface conditions below the UX. A camera takes images of the ground earlier and then shows them on the display so the driver can have an idea what the vehicle is travelling over. The relative orientation of the wheels is also visible, which can be helpful on rough terrain with obstacles.

Inside the new UX, the multimedia infotainment system at the centre of the dashboard has been revised and now uses the new Lexus Interface system. This provides a larger touchscreen display (8 inches of 12.3 inches) that is positioned close to the driver. The display has higher resolution and smartphone-like anti-glare technology and instead of the remote controlled, users can now interact with the system through intuitive touch and voice activation controls.

The overall cabin usability has been improved by optimizing the shapes and switch layout of the instrument panel and console area with LED lighting added. Taking into consideration how people are using more personal electronic devices these days and require recharging, the interior designers have added two USB charging points at the front, and also improved the wireless charging space.

The Lexus Interface incorporates a new Voice Assistant available through voice activation or accessible via a button on the steering wheel, providing handsfree operation. Simple phrases like “Hey Lexus” trigger the system for voice commands and with a human-centred approach, the Lexus Interface Assistant allows for intuitive interaction using natural language.

For clear communication with the system, there are two microphones with enhanced noise-cancellation, seat detection and speaker location capabilities. The system gives front seat occupants an expanded and interactive experience to access media, phone and vehicle settings.

Depending on the market, the driver can also have access to Cloud Navigation, Destination Assist and other Intelligent Assistant features. The cloud navigation offered through Drive Connect allows for real-time Over-the-Air updates for traffic and routing information and Points of Interest. With Wi-Fi Connect, the Intelligent Assistant can also offer integrated audio streaming functionality.

Needless to say, the Lexus Interface support wireless Apple CarPlay and Android Auto with compatible smartphones and also has dual Bluetooth phone connectivity.

Powertrains are unchanged and depending on the market, there are either combustion engines or hybrid powertrains. In Malaysia, for example, only the 2-litre 169 bhp combustion engine is available but there’s a choice of three versions.

The new UX F Sport version has enhancements as well, both visually and technically. The addition of a brace to the steering gear complements the standard Adaptive Variable Suspension system and rear performance dampers to absorb body flex and minor vibrations and further sharpen handling and improve overall ride comfort.

The new UX will probably take a while to appear in Malaysia, but Lexus Malaysia has just launched the new NX, another crossover SUV model positioned a notch higher. You can read our first impressions of it here.

Lexus LF-Z Electrified Concept

*Visit www.bhpetrol.com.my for more information.*

Over the next 4 years, Lexus will step up its electrification program and introduce up to 20 new models, with fully electric as well hybrid powertrains. As a preview of what is to come, Toyota’s luxury brand today presented to the world its LF-Z Electrified concept car. The conceptual BEV (Battery Electric Vehicle) incorporates driving performance, styling, and technologies envisioned for realization by 2025.

The LF-Z Electrified has a BEV-dedicated platform which features a new 4-wheel driving force control technology known as DIRECT4. This uses the instant responsiveness of an electric motor’s driving force to freely control a vehicle’s four wheels for superior and highly flexible driving performance that sets it apart from conventional vehicles. The system controls the distribution of driving force through the seamless orchestration and calculation of accelerator pedal application and steering wheel operation, resulting in powerful acceleration and cornering performance that aligns near-perfectly to the driver’s will.

The use of steer-by-wire eliminates the need for a mechanical connection through the steering shaft, resulting in a more direct response between steering operation and driving force. This enables the vehicle to turn with less steering angle―and more precision―in response to driving conditions.

Lexus Driving Signature
Although the LF-Z Electrified marks the move away from conventional combustion engines, future BEV models will still have the Lexus Driving Signature, a unique Lexus driving experience that aims for a linear response that is faithful to the driver’s intentions, including the feeling of seamlessly connecting deceleration, steering and acceleration in all driving situations.

The LF-Z Electrified achieves an ideal balance and inertia by optimally positioning the battery and motors. The electrification technology allows for innovative packaging and design, and raises the Lexus Driving Signature to an even higher level by significantly evolving the basic performance of the vehicle.

By orienting the battery assembly longitudinally under the floor of the vehicle, the chassis becomes more rigid and the car’s centre of gravity is lowered for improved dynamics. In addition, this layout helps mitigate vibrations and unpleasant noises from penetrating the passenger cabin upholding the Lexus DNA of quietness and ride comfort.

With a 90 kWh lithium-ion battery pack, the LF-Z Electrified, which is said to weigh 2,100 kgs, is expected to have a range of up to 600 kms. The total system output of 400 kW/700 Nm will be able to accelerate it from 0 to 100 km/h in a projected 3 seconds and reach a maximum speed of 200 km/h.

Styling continues to evolve
Measuring 4880 mm in overall length and 1960 mm in overall width, the LF-Z Electrified’s sculpted and emotional exterior strongly accentuates the uniqueness of Lexus design. It suggests the direction of the evolution of Lexus styling where the overall form, which starts low in the front and peaks toward the rear, is composed of a continuous silhouette centered on a smooth cabin.

Large-diameter wheels that transmit the power of the high-power electric motors to the road surface are situated as much as possible at the vehicle’s four corners for a wide stance with a low centre of gravity.

Lexus designers took up the challenge of evolving the Lexus design icon of the spindle shape into a spindle body as the overall body architecture in a new form of expression. The aim was to create a 3-dimensional design that transforms the form of the body itself into the icon of the Lexus brand and to continuously develop functional expressions and styling that keep abreast with the evolution of technology.

The use of DIRECT4, which freely controls the driving force of the four wheels, enabled styling that evokes the image of dynamic driving in which the distribution of driving force is linearly shifted. The accentuation of the doors fluently transitions from the front wheels to the rear wheels, which are surrounded by shiny, projecting, flare-shaped molding.

In the rear, a clean and simple horizontal design combines with the molding that emphasizes the projecting wheels to express a powerful stance in support of a torque-strong driving force. Also, horizontally displaying ‘LEXUS’ in the continuous slender rear combination lamp contributes to styling that, along with the front of the vehicle, symbolizes the next generation of Lexus.

Tazuna cockpit with true Omotenashi
To provide a uniquely BEV driving experience, the interior is equipped with a ‘Tazuna’ cockpit and features an open and minimalist design. ‘Tazuna’ (Japanese for ‘rein’) refers to the relationship between horse and rider, who communicate through a single rein. While the cockpit is a key focal point, the low positioning of the instrument panel relative to the vehicle occupants and other measures are used to express a refreshing minimalism and a space that offers true Omotenashi (hospitality).

The entire interior has been made a clean and high-quality space by a form that seamlessly connects the cowl to the front doors and on to the rear doors. Also, a panoramic roof uses long plates of glass that bring about a feeling of openness, emphasizing the minimalist environment.

In the LF-Z Electrified, Artificial Intelligence (AI), which learns the driver’s preferences and behavioural characteristics, provides constant support to the driver. Voice communication contributes to improved operability while driving. The voice recognition system uses the latest AI to recognize, learn, and adapt to a driver’s habits and preferences, supporting with tasks such as determining driving routes and even making restaurant reservations. Ultimately, it becomes the driver’s ‘concierge’ and partner for every journey.

Lexus is also working with Mark Levinson, its long-time partner in the audio field, to develop a system which can reproduce a concert hall-like audio experience. With the next-generation sound management function, active noise cancellation facilitates interaction or privacy amongst passengers, providing a quiet and comfortable interior space.

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.
