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 Rolls-Royce Phantom doesn’t offer height-adjustable seat belts.
The Lexus LS 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 Phantom doesn’t offer a front passenger side knee airbag.
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 Phantom doesn’t offer backup collision prevention brakes.
The LS offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Phantom doesn’t offer all-wheel drive.
Both the LS and Phantom have rear cross-traffic warning, but the LS has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The Phantom’s Cross Traffic Warning doesn’t automatically brake.
Both the LS and the Phantom have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
