Both the Flying Spur and AMG S-Class have child safety locks to prevent children from opening the rear doors. The Flying Spur has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The AMG S-Class’ child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Bentley Flying Spur 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 AMG S-Class doesn’t offer a front passenger side knee airbag.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Flying Spur. But it costs extra on the AMG S-Class.
To help make backing out of a parking space safer, the Flying Spur has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the AMG S-Class.
Both the Flying Spur and the AMG S-Class have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, available night vision systems and lane departure warning systems.
