For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG S-Class Coupe 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 Aston Martin DBS doesn’t offer pretensioners for the rear seat belts.
The AMG S-Class Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The DBS doesn’t offer pre-crash pretensioners.
The AMG S-Class Coupe has standard NECK-PRO Front Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash.

The AMG S-Class Coupe has standard Active Brake Assist, which use forward mounted sensors to warn the driver of a possible collision ahead.

The DBS doesn't offer collision warning or crash mitigation brakes.
The AMG S-Class Coupe has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The DBS doesn’t offer all-wheel drive.
An active infrared night vision system optional on the AMG S-Class Coupe 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 displays the image on a monitor in the dashboard and even aims one of the vehicle’s headlights in the direction of the person or object. The DBS doesn’t offer a night vision system.
The AMG S-Class Coupe’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The DBS doesn’t offer a lane departure warning system.

The AMG S-Class Coupe has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy.

A nine-speed automatic is standard on the Mercedes AMG S-Class Coupe, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the DBS.
All wheel drive, available in the AMG S-Class Coupe, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Aston Martin DBS is not available with all wheel drive.
The AMG S-Class Coupe’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The DBS doesn’t offer launch control.
For better stopping power the AMG S-Class Coupe’s optional brake rotors are larger than those on the DBS:
The front and rear suspension of the AMG S-Class Coupe uses air springs for a smoother, controlled ride than the DBS, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.
The AMG S-Class Coupe has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The AMG S-Class Coupe’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The DBS doesn’t offer a load leveling suspension.
The AMG S-Class Coupe’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The DBS doesn’t offer drift compensation steering.
For a smoother ride and more stable handling, the AMG S-Class Coupe’s wheelbase is 5.5 inches longer than on the DBS (115.9 inches vs. 110.4 inches).

The design of the Mercedes AMG S-Class Coupe amounts to more than styling. The AMG S-Class Coupe has an aerodynamic coefficient of drag of .33 Cd. That is significantly lower than the DBS (.38). A more efficient exterior helps the AMG S-Class Coupe go faster and keeps the interior quieter. It also helps the AMG S-Class Coupe get better fuel mileage.

The AMG S-Class Coupe has a larger trunk than the DBS Coupe (10.4 vs. 9.5 cubic feet).
With its coupe body style, valet key and remote trunk release lockout, the AMG S-Class offers cargo security. The DBS’ non-lockable remote release defeats cargo security.
A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the AMG S-Class Coupe. The DBS doesn’t offer locking storage for small valuables.
To make loading and unloading groceries and cargo easier when your hands are full, the AMG S-Class Coupe’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The DBS doesn’t offer a power or hands-free opening trunk.
The AMG S-Class Coupe has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The DBS doesn’t offer a remote starting system.
The AMG S-Class Coupe has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The DBS doesn’t offer a heads-up display.
Heated windshield washer fluid is standard on the AMG S-Class Coupe to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The DBS doesn’t offer heated windshield washer fluid.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the AMG S-Class Coupe has standard extendable sun visors. The DBS doesn’t offer extendable visors.
The AMG S-Class Coupe’s sun-visors swivel front-to-side to block glare from the side windows. The DBS’ visors are fixed into the windshield header.
A power rear sunshade is standard in the AMG S-Class Coupe to help block heat and glare for the rear passengers. The DBS doesn’t offer a rear sunshade.
The AMG S-Class Coupe has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The DBS has an automatic rear view mirror, but its side mirrors don’t dim.
Both the AMG S-Class Coupe and the DBS have standard heated front seats. The AMG S-Class Coupe also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the DBS.
