The Lexus RZ has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Wagoneer S doesn’t offer a front passenger side knee airbag.
The RZ has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Wagoneer S doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Full-time four-wheel drive is available on the RZ. Full-time four-wheel drive gives added traction for safety in all conditions, not just off-road, like the only system available on the Wagoneer S.
Both the RZ and Wagoneer S have rear cross-traffic warning, but the RZ Premium/Luxury has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The Wagoneer S’ Rear Cross Path Detection doesn’t automatically brake.
Both the RZ and the Wagoneer S have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
The Lexus RZ achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Wagoneer S has not yet been evaluated by the IIHS for 2024.
