Compare the2025 Bentley Flying SpurVS 2025 Mercedes AMG S-Class

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 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 AMG S-Class doesn’t offer a front passenger side knee airbag.

An active infrared night vision system optional on the Flying Spur helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then projects the image on the windshield, near the driver’s line of sight. The AMG S-Class doesn’t offer a night vision system.

Both the Flying Spur and the AMG S-Class have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, 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, around view monitors and rear cross-path warning.

The Flying Spur comes with a full 3-year/unlimited-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The AMG S-Class’ 50,000-mile basic warranty expires sooner.

The Flying Spur SPEED can travel with zero emissions on electricity, only, on a full charge for 47 miles, up to 10% further than the AMG S 63 E‘s -mile range on a full charge and a full tank of fuel. The AMG S 63 E has to start its internal combustion engine after only 16 miles.

An engine control system that can shut down some of the engine’s cylinders helps improve the Flying Spur (except Hybrid)’s fuel efficiency. The AMG S-Class doesn’t offer a system that can shut down part of the engine.

The Flying Spur’s 275/35R22 front and 315/30R22 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the AMG S-Class’ standard 45 series front and 40 series rear tires. The Flying Spur’s tires are lower profile than the AMG S-Class’ optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the Flying Spur has standard 22-inch wheels. Smaller 20-inch wheels are standard on the AMG S-Class. The AMG S-Class’ largest wheels are only 21-inches.
