At the heart is a new eAxle system that provides three levels of output: 224 horsepower in the RZ 350e, 380 horsepower in the RZ 500e, and 408 horsepower in the RZ 550e F Sport. Moreover, charging performance has been enhanced with revisions to the battery structure itself as well as a new 22-kW AC onboard charger. Lexus has also added a new battery pre-conditioning function in cold weather.

Across the models, it has a 76.96-kWh lithium ion battery offering up to 575 kilometers of range in the RZ 350e, 500 kilometers in the RZ 500e, and 450 kilometers in the RZ 550e F Sport.

Along with the newfound performance, Lexus has finally put into production its steer-by-wire system. The steering wheel, now almost rectangular in shape, has a 200-degree full left or right lock. The steering gear ratio adjusts dynamically according to vehicle speed. Since there’s no physical link between the steering wheel and the axles, the driver receives appropriate feedback communicated by electric signals, minimizing unpleasant vibrations.

The solitary F Sport model gets Interactive Manual Drive that allows drivers to control the power output of the RZ550e F Sport with the paddle shifters, as if using an 8-speed manual gearbox. Operation is accompanied by real-time feedback through the throttle as well as replicated engine sounds and even a rev limiter.

The RZ’s Direct4 system has also been tweaked for 2025. At start-off and in straight-line acceleration, front/rear power distribution is controlled between 60/40 to 0/100 to suppress pitching and produce a direct acceleration feel. During cornering, the distribution ratio is optimized between 80/20 and 0/100, according to vehicle speed and steering angle, to match the driving conditions.

During turn-in, more power is directed to the front axle to achieve a smooth turn. When exiting a corner, torque distribution is in line with the load on each wheel, to maintain vehicle balance and allow for smooth acceleration.

The chassis and body structure has also been refined with improvements to the radiator support and the addition of a rear brace. The springs and dampers have also been tweaked for improved performance, stability, and ride.

In the pursuit of quietness, a new floor silencer has been put beneath the rear seats. Furthermore, soundproofing has been added to the tonneau cover, back door trim, and load compartment.

There aren’t much changes outside save for the new F Sport variant with its 20-inch aero-design wheels, unique Neutrino Gray color, and “function-driven” changes to the bumpers, brake ducts, and spoilers.

Inside, Lexus has created a cabin trim that features the world’s first laser-processed graphics applied to Ultrasuede. Made from sustainable 30 percent plant-based materials, this new door trim creates a new “luxury expression.” In another first, the multi-color ambient lighting has a new, dynamic shadow effect. A new dimming function of the panoramic roof helps keep the cabin comfortable in bright sunshine. By reducing reflections, it has made it possible to use both the dimmable roof and an electronic rearview mirror simultaneously. Further differentiating the F Sport, it gets a blue and dark gray interior and a trim panel finished in a “Microgeometic” pattern. Other additions include special scuff plates and an aluminum pedal set.
