The all-electric Lexus RZ 450e

The groundbrea­king new vehicle designed from a clean slate

- By INIGO S. ROCES

The shift to electrific­ation deserves nothing less than the keenest attention to detail. It is with this belief that Lexus’ first battery electric vehicle (BEV) the RZ450E was designed from the ground up. The intention is not simply to deliver the benefits of zero emission, all-electric driving, but to capture the potential of BEVS to reinvent the driving experience.

Rather than adapting an internal combustion vehicle platform to accommodat­e a BEV powertrain, building a car on an all-new battery electric platform opens up new design opportunit­ies.

A dedicated BEV look

The new, dedicated BEV platform and electric powertrain give the RZ a lower center of gravity and allow for a lower nose profile. These allow the RZ to have a sleeker-looking cabin section that still offers optimum headroom for even the rear passengers. Without the need for drive axles connected to the engine, the wheels and motors can also be pushed out to the corners, giving the vehicle shorter overhangs, a longer wheelbase, better handling, and more interior legroom. The allows the RZ to maintain the size of a mid-size SUV, while offering the interior space of a larger sedan or SUV, and the performanc­e of a sports car.

These have also paid dividends in the design department. From the side view, the design begins with a low nose profile, flowing toward a rearward peak in the roofline. This look creates volume around the front wheels, illustrati­ng the power in the front axle, while the rear wheels gain a “torqueful” look. The doors have contrastin­g forms and striking surface treatments, creating a seamless visual sweep from front to rear.

The front façade bears the familiar spindle grille shape more deeply integrated into the complete frontal design, generating a stronger threedimen­sional effect. Because an electric powertrain requires less cooling airflow than a combustion engine, the area is instead finished in the car’s body color. The new-design headlight units are unified with the spindle body. Combined with the blacking out of the bumper corners, they add emphasis to the central spindle shape, establishi­ng a distinctiv­e Lexus BEV look.

The rear presents a cool, hightech look with a split roof spoiler that extends the design’s rearward flow and contribute­s to the car’s stable performanc­e. The elongated LED light bar across the width of the car wraps around the muscular rear quarters with an exceptiona­lly thin center section.

Human-centered interior

The interior is a light and open space that is both simple and luxurious, expressing Lexus Omotenashi hospitalit­y and Takumi craftsmans­hip. The RZ’S cabin has an open, spacious and airy feel with a driver-focused cockpit. Lexus has introduced a number of human-centred advanced technology features that enhance comfort, convenienc­e and life on board.

The RZ’S cockpit brings together the driver’s position at the wheel and a precise arrangemen­t of meters, controls and displays to create a space where the driver needs only to make small movements of the hand and eye to operate the vehicles. The layout of the controls and informatio­n sources – 14inch center multimedia display, meters, multi-informatio­n display and head-up display – require minimum hand and eye movement to reach, operate and read.

The meters in the instrument binnacle can be customized to suit the driver’s preference and their appearance automatica­lly changes according to the drive mode selected. Drivers are welcomed by name (as registered with their smart key) and an animation sequence begins

The seats feature Lexus’ global architectu­re frame design and are upholstere­d with “deep-hung” seams to promote more comfortabl­e support and posture on long journeys with integrated heaters. The rear seatbacks have a two-stage recline function.

The touch-sensor switches on the steering wheel can be customized to operate the driver’s preferred functions, such as drive mode, navigation and audio. Although they work using electronic signals, they have a satisfying “click” feel to confirm operation.

The cabin atmosphere is enhanced by an ambient lighting system with a spectrum of 64 colors, grouped in 14 different themes to create the right mood for the journey.

Three interior color combinatio­ns are available –hazel, grayscale, and orage (a shade of blue) – each creating a different ambience.

Power via compact electric e-axle

Propelling the RZ is Lexus’ new eAxle, designed for use in BEVS. This is a compact, modular package which consists of a motor, gearing and an ECU, located between the driven wheels. The RZ uses both front and rear eaxles, which work in conjunctio­n with the DIRECT4 all-wheel drive control system to adjust the vehicle’s posture, traction and power distributi­on, according to the driving conditions. The e-axles are quiet, efficient and deliver precise power.

The e-axles produce a combined 312 hp maximum output. They are powered by a long-life 71.4 kwh lithium-ion battery expected to retain at least 90% of its capacity after 10 years of driving. The RZ achieves excellent energy efficiency, with consumptio­n rated at 16.8 kwh or 18.7 kwh per 100 km (381 – 425-km per full charge).

The RZ comes with a 2kw emergency cable and 7kw wallbox charger upon purchase of the vehicle. Battery recharging when connected to a three-phase power supply takes around six-and-a-half hours; using a one-phase supply the time is around 10 hours; connected to a DC fast-charging system, an 80% recharge can be accomplish­ed in about 30 minutes.

DIRECT4 all-wheel drive control

All four wheels are powered by DIRECT4, an exclusive Lexus technology, that constantly and seamlessly balances the drive torque between the front and rear axles. The result is stress-free performanc­e and stable handling, with intuitive operation strengthen­ing the sense of connection between driver and machine. The system uses ECU sensors to collect, evaluate and react to a range of factors, including vehicle speed, steering angle and G forces. From these inputs, it calculates and immediatel­y applies the appropriat­e drive torque to each e-axle to maximize grip and traction suitable for the road surface.

Outstandin­g safety

In addition to all of these features, the RZ 450e also comes with all the premium safety features expected of a luxury vehicle. These include a Pre-collision system, Dynamic Radar Cruise Control, Lane Departure Alert and Lane Tracing Assist, Rear Cross Traffic Alert, Rear Camera Detection, Advanced Park, Lexus e-latch with Safe Exit Assist for the doors, and a Panoramic View Monitor. These are in addition to the standard complement of airbags, ABS, Traction Control and other safety systems.

The groundbrea­king Lexus RZ 450e retails at ₱4,828,000, in only one variant. Visit Lexus Manila and Lexus at Mitsukoshi to see the allnew RZ 450e.
