For enhanced safety, the front and rear seat shoulder belts of the Lexus RC F have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The BMW 8 Series doesn’t offer pretensioners for its rear seat belts.
The RC F 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. A system to reveal vehicles in the 8 Series’ blind spot costs extra.
To help make backing out of a parking space safer, the RC F has standard Rear Cross-Traffic Alert, helping the driver avoid collisions. BMW charges extra for Cross Traffic Warning on the 8 Series.
Both the RC F and the 8 Series have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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, driver alert monitors and available rear parking sensors.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the RC F the rating of “Top Safety Pick” for 2017, a rating granted to only 206 vehicles tested by the IIHS. The 8 Series has not been tested, yet.
