Electric at Heart

Lexus has been producing hybrid electric cars since 2006 and has become a leader in the technology that has become synonymous with the brand. Now, they are pushing the electric envelope with the production of fully electric, purpose built vehicles that are not confined by the constraints traditional combustion engined cars afford.

The new RZ 450e has been built on a dedicated BEV platform from the outset and is the first in the stable to do so, allowing the marque to develop the car and its technologies to their full potential. First and foremost, the introduction of Lexus' new 'e-Axles' - a compact, modular package which consists of a motor, gearing and a PCU (Power Control Unit), located between the driven wheels - transform the way the electric RZ drives compared to its hybrid and engine powered cointerparts. This is the first application of the technology which is set to roll out across future model releases using compact motor units in both the front and the rear that work with the new Direct4 all-wheel electronic drive torque control. What this means for you is imperceptible adjustments to the car's posture, traction and power distribution that are automatically undertaken according to the driving conditions. lexus.co.uk

What's more, their compact design and dimensions - short front e-Axle and low rear e-Axle - contribute to the car’s design, offering gains in cabin space for improved passenger comfort and a low load compartment floor, while also providing more space to accommodate the all important battery beneath the vehicle floor.

The paired Direct4 system which is an exclusive Lexus technology, is an intelligent system that constantly and seamlessly balances the drive torque between the front and rear axles. Further improving the cars performance and stable handling, with intuitive engagement strengthens the sense of connection between driver and machine despite the fully electric control.

This is a highly technologically charged car, with the system using ECU (Engine Control Unit) sensors to collect, evaluate and react to a range of factors, including vehicle speed, steering angle and G forces. These data points mean it can calculate and immediately apply the appropriate drive torque to each e-Axle to maximise grip and traction suitable for the road surface in milliseconds.

Of course, with the slimed-down powertrain compared to a traditional engine and drivetrain setup, the new platform affords considerable freedoms in the design department. On the outside, the signature Lexus shape in the vehicle’s body remains, with its angular yet flowing lines creating a beautiful dance between light and shadow combined with new, striking lighting design and an athletic, pointed profile - achievable thanks to the BEV platform which also lowers the centre of gravity. The platform surprisingly allows for more space and comfort for driver and passengers too, despite the sleek, seamingly low roofline, there is actually increased headroom for passengers.

Meanwhile, the interior lends itself to a light, open space that combines simple, clean design and luxurious appointment of material and finish. The perfect expression of Lexus omotenashi hospitality and takumi craftsmanship.

For the driver it's not just about cabin comfort, but driving comfort as well. Thankfully, there are four selectable drive modes, including an exclusive 'Range' mode to choose from allowing you to adjust the RZ’s performance and driving character. In Normal mode, an optimal balance of performance and power consumption is provided to suit a wide range of driving situations, perfect for your everyday driving. If you would prefer to preserve power, Eco mode is ideal, generating less drive torque in response to accelerator inputs and suppressing the air conditioning - not the best option for those warmer days. Alternatively, to maximise performance, slip it into Sport mode where you'll find a stronger steering feel and sharper accelerator response. You can also set your preferred powertrain, chassis and air conditioning modes using a Custom mode, accessed via the vast multimedia touchscreen.

Maximising realworld range is at the forefront of EV drivers minds and the RZ's Range mode allows you to do that by reducing power consumption, restricting power output and vehicle speed and turning the air conditioning off. Also, when Range mode is selected, the balance of Direct4 front/rear drive torque distribution is also optimised for power efficiency. When driving in the low torque range, only the rear motor is used; the front motor is brought into play as the torque level increases. If any wheelspin is detected, normal AWD operation resumes.

A first for Lexus, this is a technologically packed piece of electric engineering that demonstrates the future of the brand and it does so in style. The SUV design delivers a sleek, compact exterior aesthetic while offering substantial style and space inside.
