2023 Lexus RZ 450e LUXURY PACKAGE / FULLY ELECTRIC / DIRECT 4...

The future of Lexus Electrified has arrived with the introduction of the all-new, all-electric Lexus RZ 450e. The RZ is the brand’s first globally available, purpose-built battery-electric vehicle that brings a dynamic driving experience and distinctive design focused on performance.With its new lightweight e-TNGA steel platform (a first for Lexus), the RZ possesses an optimal placement of mass and high body rigidity. RZ’s body employs high-tensile steel panels and an aluminum hood to reduce weight and increase rigidity. Marrying body and platform is a bevy of innovative technologies, including Laser Screw Welding and Laser Peening, short pitch spot welds, and high rigidity expansion joints.The lightweight platform also offers enhanced stability and ride comfort by mounting the 96-cell lithium-ion battery pack, developed by Prime Planet Energy & Solutions (PPES), under the vehicle floor, creating a low centre of gravity and inertia movement. A urethane sealant helps to keep dust and water out of the stack’s reinforced structure, while efficient water-cooling and water-heating systems work to maintain an ideal battery temperature.The 71.4 kWh battery delivers on performance with a total system output rating of 308 hp and a manufacturer-estimated 0-100 km/h acceleration time of 5.3 seconds. It has an NRCan-estimated range rating of up to 354 km when equipped with 18” wheels and an NRCan-estimated equivalent fuel consumption rating of 2.0/2.4/2.2 Le/100 km (city/highway/combined). When equipped with 20” wheels, the RZ has an NRCan-estimated equivalent fuel consumption rating of 2.3/2.7/2.5 Le/100 km with an NRCan-estimated range of up to 315 km.RZ 450e utilizes DIRECT4, an all-wheel drive system first introduced with the 2023 Lexus RX, which features a rear eAxle coupled with the engine and front motor. RZ’s DIRECT4 system utilizes two high-output, high-torque eAxle units that each drive a wheel set, one in the front (150-kW) and the other at the rear (80-kW). Three-point eAxle motor mounts, each using a lightweight aluminum bracket, are placed symmetrically on each side to counterbalance the eAxle’s torque.The DIRECT4 system works to optimize RZ’s drive force, traction, and posture control (e.g., pitch and dive) in accordance with driving conditions and the load carried by each wheel. DIRECT4’s front-to-rear torque distribution has a maximum range of 100:0 to 0:100, depending on the driving situation.Also lending to the RZ’s drive performance is the front MacPherson strut type suspension and rear trailing arm double-wishbone configuration with both specifically tuned and located to enhance handling balance, roll posture, and ride comfort.Lexus Driving Signature is also reflected in the new Active Hydraulic Booster-G (AHB-G) braking system that works with the DIRECT4 system and RZ’s regenerative motor capability to reduce vehicle speed while helping to improve vehicle posture. With a new Vehicle Stability Control actuator and on-demand pressurizing system using a high-performance pump motor, this braking system provides a natural and responsive brake pedal feel. The front-to-rear brake force distribution is controlled by independent pressure regulation, contributing to a comfortable drive and stable vehicle composure while braking. Furthermore, ergonomic brake pedal pads are used for easy pedal changes and pedal depression.In addition, an all-new Vehicle Braking Posture Control program adjusts front-to-rear brake force distribution according to a driver’s braking input as well as the suspension’s vertical inputs. This aims to improve handling and body posture while braking and turning.Lexus’ identifiable spindle grille is replaced by the Lexus spindle body, as introduced with the 2023 Lexus RX, showcasing a distinctive roof spoiler to suppress aerodynamic force. The roof, trunk and undercover are shaped to reduce aerodynamic drag and allow air to flow smoothly across the vehicle.
