For enhanced safety, the front and rear seat shoulder belts of the Lexus LS 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 Gran Coupe doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Lexus LS are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 8 Series Gran Coupe doesn’t offer height-adjustable seat belts.
Over 200 people are killed each year when backed over by motor vehicles. The LS has a standard Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 8 Series Gran Coupe doesn’t offer backup collision prevention brakes.
The LS 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 Gran Coupe’s blind spot costs extra.
To help make backing out of a parking space safer, the LS has standard Rear Cross-Traffic Alert and Parking Support Brake automatically engages the brakes to help avoid a collision. BMW charges extra for Cross Traffic Warning on the 8 Series Gran Coupe and the 8 Series Gran Coupe’s Cross Traffic Warning does not include automatic braking.
Both the LS and the 8 Series Gran Coupe 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, post-collision automatic braking systems, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors, available all wheel drive and around view monitors.
