For enhanced safety, the front and rear seat shoulder belts of the Lexus RC have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Subaru BRZ doesn’t offer pretensioners for its rear seat belts.
The RC’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The BRZ doesn’t offer pre-crash pretensioners.
The Lexus RC 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 BRZ doesn’t offer a front passenger side knee airbag.
The RC offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The BRZ doesn’t offer all-wheel drive.
The RC offers optional Intuitive Park Assist to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The BRZ doesn’t offer a front parking aid.
The RC has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the BRZ Limited offers a blind spot warning system.
To help make backing out of a parking space safer, the RC has standard Rear Cross-Traffic Alert, helping the driver avoid collisions. Only the BRZ Limited offers Rear Cross Traffic Alert.
Both the RC and the BRZ have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.
The Lexus RC weighs 856 to 1071 pounds more than the Subaru BRZ. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
