For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG C 63 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 Cadillac ATS-V doesn’t offer pretensioners for the rear seat belts.
The AMG C 63 Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The ATS-V doesn’t offer pre-crash pretensioners.
Using vehicle speed sensors, smart airbags in the AMG C 63 Coupe deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The AMG C 63 Coupe’s side airbags will shut off if a child is leaning against the door. The ATS-V’s airbags don’t have smart features and will always deploy full force.
The AMG C 63 Coupe has standard Active Brake Assist, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The ATS-V offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.
The AMG C 63 Coupe offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The ATS-V only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The AMG C 63 Coupe’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The ATS-V doesn’t offer a driver alert monitor.
Both the AMG C 63 Coupe and the ATS-V have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available lane departure warning systems.

The AMG C 63 Coupe’s standard 4.0 turbo V8 produces 5 more horsepower (469 vs. 464) and 34 lbs.-ft. more torque (479 vs. 445) than the ATS-V’s 3.6 turbo V6. The AMG C 63 S Coupe’s standard 4.0 turbo V8 produces 39 more horsepower (503 vs. 464) and 71 lbs.-ft. more torque (516 vs. 445) than the ATS-V’s 3.6 turbo V6.
On the EPA test cycle the AMG C 63 Coupe gets better fuel mileage than the ATS-V Auto (17 city/26 hwy vs. 17 city/25 hwy). The AMG C 63 Coupe gets better fuel mileage than the ATS-V Manual (17 city/26 hwy vs. 16 city/23 hwy).
In heavy traffic or at stoplights the AMG C 63 Coupe’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The ATS-V doesn’t offer an automatic engine start/stop system.
The AMG C 63 Coupe has 1.4 gallons more fuel capacity than the ATS-V (17.4 vs. 16 gallons), for longer range between fill-ups.
In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG C 63 Coupe higher (5 out of 10) than the Cadillac ATS-V (3). This means the AMG C 63 Coupe produces up to 16.5 pounds less smog-producing pollutants than the ATS-V every 15,000 miles.
The Mercedes AMG C 63 Coupe comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the ATS-V.
A nine-speed automatic (SMG) is standard on the Mercedes AMG C 63 Coupe, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the ATS-V.
The AMG C 63 Coupe offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The ATS-V doesn’t offer an SMG.
To facilitate fast shifting and allow the driver to focus on the road, the AMG C 63 Coupe has a standard up-shift light to indicate when the engine is approaching redline. The ATS-V doesn’t offer an up-shift light.
For better stopping power the AMG C 63 S Coupe’s brake rotors are larger than those on the ATS-V:
AMG C 63 S Coupe
The AMG C 63 Coupe S offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The ATS-V doesn’t offer ceramic brake rotors.
The AMG C 63 Coupe stops shorter than the ATS-V:

Car and Driver
The AMG C 63 S Coupe’s optional 285/30R20 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the ATS-V’s 35 series tires.
For better ride, handling and brake cooling the AMG C 63 S Coupe offers optional 19-inch front and 20-inch rear wheels. The ATS-V’s largest wheels are only 18-inches.
The AMG C 63 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 ATS-V doesn’t offer drift compensation steering.
For a smoother ride and more stable handling, the AMG C 63 Coupe’s wheelbase is 2.5 inches longer than on the ATS-V (111.8 inches vs. 109.3 inches).
For better handling and stability, the track (width between the wheels) on the AMG C 63 Coupe is 3.9 inches wider in the front and 1.3 inches wider in the rear than on the ATS-V.
The AMG C 63 S Coupe handles at .98 G’s, while the ATS-V pulls only .97 G’s of cornering force in a Car and Driver skidpad test.
For better maneuverability, the AMG C 63 Coupe’s turning circle is 1.3 feet tighter than the ATS-V’s (37.1 feet vs. 38.4 feet).
The AMG C 63 Coupe has 1.2 inches more front headroom, .7 inches more front shoulder room, .5 inches more rear headroom and .6 inches more rear shoulder room than the ATS-V.
With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the AMG C 63 offers cargo security. The ATS-V’s non-lockable folding seat defeats cargo security.
To make loading and unloading groceries and cargo easier when your hands are full, the AMG C 63 Coupe’s power trunk can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The ATS-V doesn’t offer a power or hands-free opening trunk.
Unlike the driver-only memory system in the ATS-V, the AMG C 63 Coupe has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.
If the windows are left open on the AMG C 63 Coupe the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the ATS-V can only operate the windows from inside the vehicle, with the ignition on.
The AMG C 63 Coupe’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The ATS-V’s standard manually variable intermittent wipers have to be constantly adjusted.
Optional air-conditioned seats in the AMG C 63 Coupe keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The ATS-V doesn’t offer air-conditioned seats.
The AMG C 63 Coupe has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable. The ATS-V doesn’t offer a rear seat center armrest.
To keep a safe, consistent following distance, the AMG C 63 Coupe offers an optional Distronic Plus, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The ATS-V doesn’t offer an adaptive cruise control.
The AMG C 63 Coupe’s optional Active Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The ATS-V doesn’t offer an automated parking system.
The Mercedes AMG C 63 comes in coupe, convertible and sedan bodystyles; the Cadillac ATS-V isn’t available as a convertible or sedan.
