To maximize occupant safety, the front and rear seat shoulder belts of the Mercedes AMG C-Class Coupe have pretensioners to eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Toyota Supra doesn’t offer pretensioners.
The AMG C-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 Supra doesn’t offer pre-crash pretensioners.
Using vehicle speed sensors, smart airbags in the AMG C-Class 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-Class Coupe’s side airbags will shut off if a child is leaning against the door. The Supra’s airbags don’t have smart features and will always deploy full force.
The AMG C 43 Coupe has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Supra doesn’t offer all-wheel drive.
The AMG C-Class Coupe offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Supra 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.
Both the AMG C-Class Coupe and the Supra 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, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available lane departure warning systems and rear cross-path warning.
The Mercedes AMG C-Class Coupe weighs 582 to 737 pounds more than the Toyota Supra. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
The AMG C-Class Coupe comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Supra’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.
The AMG C 43 Coupe’s standard 3.0 turbo V6 produces 50 more horsepower (385 vs. 335) and 19 lbs.-ft. more torque (384 vs. 365) than the Supra’s 3.0 turbo 6-cylinder. The AMG C 63 Coupe’s standard 4.0 turbo V8 produces 134 more horsepower (469 vs. 335) and 114 lbs.-ft. more torque (479 vs. 365) than the Supra’s 3.0 turbo 6-cylinder. The AMG C 63 S Coupe’s standard 4.0 turbo V8 produces 168 more horsepower (503 vs. 335) and 151 lbs.-ft. more torque (516 vs. 365) than the Supra’s 3.0 turbo 6-cylinder.

The AMG C-Class Coupe has 3.7 gallons more fuel capacity than the Supra (17.4 vs. 13.7 gallons), for longer range between fill-ups.
In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG C-Class Coupe higher (5 out of 10) than the Toyota Supra (3). This means the AMG C-Class Coupe produces up to 16.5 pounds less smog-producing pollutants than the Supra every 15,000 miles.
A nine-speed automatic (SMG) is standard on the Mercedes AMG C-Class Coupe, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Supra.
The AMG C-Class Coupe offers an available 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 Supra doesn’t offer an SMG or a conventional manual transmission.
All-wheel drive, available in the AMG C-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 Toyota Supra is not available with all-wheel drive.
For better stopping power the AMG C-Class Coupe’s front brake rotors are larger than those on the Supra:
AMG C 43 Coupe
AMG C 63 S Coupe
Opt Rear Rotors
The AMG C-Class 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 Supra doesn’t offer ceramic brake rotors.
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 Supra’s 35 series tires.
For better ride, handling and brake cooling the AMG C 63 S Coupe offers optional 20-inch rear wheels. The Supra’s largest wheels are only 19-inches.
Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the AMG C-Class Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Supra doesn’t offer run-flat tires.
The AMG C-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 Supra doesn’t offer drift compensation steering.
For a smoother ride and more stable handling, the AMG C-Class Coupe’s wheelbase is 14.6 inches longer than on the Supra (111.8 inches vs. 97.2 inches).
The AMG C-Class Coupe has standard seating for 4 passengers; the Supra can only carry 2.

The AMG C-Class Coupe has .5 inches more front headroom and .4 inches more front shoulder room than the Supra.
The AMG C-Class Coupe has a larger trunk than the Supra (10.5 vs. 10.2 cubic feet).
With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the AMG C-Class offers cargo security. The Supra’s hatchback body style and non-lockable remote release defeat cargo security.
To make loading and unloading groceries and cargo easier when your hands are full, the AMG C-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 Supra doesn’t offer a power or hands-free opening trunk.
J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Toyota. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 30% lower rating, Toyota is ranked 14th.
Unlike the driver-only memory system in the Supra, the AMG C-Class 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.
The AMG C-Class Coupe’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The Supra doesn’t offer an easy entry system.
Keyless-Go standard on the AMG C-Class Coupe allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Toyota Supra’s Smart Key System doesn’t unlock the trunk.
To help drivers see further while navigating curves, the AMG C-Class Coupe offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Supra doesn’t offer cornering lights.
To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the AMG C-Class Coupe has standard extendable sun visors. The Supra doesn’t offer extendable visors.
The AMG C-Class Coupe’s sun-visors swivel front-to-side to block glare from the side windows. The Supra’s visors are fixed into the windshield header.
Optional air-conditioned seats in the AMG C-Class Coupe keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Supra doesn’t offer air-conditioned seats.
The AMG C-Class Coupe’s available GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Supra’s available navigation system doesn’t offer real-time traffic updates.
The AMG C-Class Coupe’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Supra doesn’t offer an automated parking system.
The Mercedes AMG C-Class comes in coupe, convertible and sedan bodystyles; the Toyota Supra isn’t available as a convertible or sedan.
