For enhanced safety, the front and rear seat shoulder belts of the Lexus LC have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW 8 Series doesn’t offer pretensioners for its rear seat belts.
The LC 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 LC has standard Rear Cross-Traffic Alert, helping the driver avoid collisions. BMW charges extra for Cross Traffic Warning on the 8 Series.
Both the LC and the 8 Series have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, 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.
