The Rolls-Royce Spectre has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 EQE Sedan doesn’t offer a front passenger side knee airbag.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Spectre. But it costs extra on the EQE Sedan.
Both the Spectre and the EQE Sedan 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, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
The Rolls-Royce Spectre weighs 909 to 1108 pounds more than the Mercedes EQE Sedan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
