In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the RZ are reminded to check the back seat if they opened the rear door before starting out. The Polestar 2 doesn’t offer a back seat reminder.
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 Polestar 2 doesn’t offer a front passenger side knee airbag.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the RZ. But it costs extra on the Polestar 2.
To help make backing out of a parking space safer, the RZ has standard Rear Cross-Traffic Alert and Parking Support Brake automatically engages the brakes to help avoid a collision. Polestar charges extra for rear cross-path warning on the Polestar 2.
Both the RZ and the Polestar 2 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, post-collision automatic braking systems, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.
