Safety

The GT-R has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The AMG C 63 Coupe doesn’t offer all-wheel drive.

Both the GT-R and the AMG C 63 Coupe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.

Warranty

Nissan’s powertrain warranty covers the GT-R 1 year and 10,000 miles longer than Mercedes covers the AMG C 63 Coupe. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the AMG C 63 Coupe ends after only 4 years or 50,000 miles.

There are almost 3 times as many Nissan dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the GT-R’s warranty.

Reliability

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Nissan vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Nissan 7th in initial quality, above the industry average. With 8 more problems per 100 vehicles, Mercedes is ranked 12th, below the industry average.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Nissan vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Nissan 3 places higher in reliability than Mercedes.

Engine

The GT-R’s standard 3.8 turbo V6 produces 96 more horsepower (565 vs. 469) than the AMG C 63 Coupe’s standard 4.0 turbo V8. The GT-R’s 3.8 turbo V6 produces 62 more horsepower (565 vs. 503) than the AMG C 63 S Coupe’s standard 4.0 turbo V8. The GT-R Track Edition/NIMSO’s standard 3.8 turbo V6 produces 97 more horsepower (600 vs. 503) than the AMG C 63 S Coupe’s standard 4.0 turbo V8.

Fuel Economy and Range

The GT-R has 2.1 gallons more fuel capacity than the AMG C 63 Coupe (19.5 vs. 17.4 gallons), for longer range between fill-ups.

Drivetrain

All wheel drive, available in the GT-R, 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 Mercedes AMG C 63 Coupe is not available with all wheel drive.

Brakes and Stopping

For better stopping power the GT-R’s brake rotors are larger than those on the AMG C 63 Coupe:

Tires and Wheels

For better traction, the GT-R has larger tires than the AMG C 63 Coupe (F:255/40R20 & R:285/35R20 vs. F:245/35R19 & R:265/35R19).

For better ride, handling and brake cooling the GT-R has standard 20-inch wheels. Smaller 18-inch wheels are standard on the AMG C 63 Coupe. The AMG C 63 Coupe’s largest wheels are only 19-inches in the front and 20-inches in the rear.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the GT-R can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The AMG C 63 Coupe doesn’t offer run-flat tires.

Chassis

The Nissan GT-R may be more efficient, handle and accelerate better because it weighs about 200 to 250 pounds less than the Mercedes AMG C 63 Coupe.

To almost totally eliminate engine vibration in the passenger area, the GT-R has a liquid-filled front engine mount. The liquid helps further dampen engine harshness. The AMG C 63 Coupe uses conventional solid rubber engine mounts.

The design of the Nissan GT-R amounts to more than styling. The GT-R has an aerodynamic coefficient of drag of .26 Cd. That is significantly lower than the AMG C 63 Coupe (.33). A more efficient exterior helps the GT-R go faster and keeps the interior quieter. It also helps the GT-R get better fuel mileage.

The GT-R uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The AMG C 63 Coupe doesn’t offer active noise cancellation.

Ergonomics

The GT-R’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The AMG C 63 Coupe does not have an oil pressure gauge.

The GT-R’s standard power windows have a locking feature to keep children from operating them. Mercedes does not offer a locking feature on the AMG C 63 Coupe’s standard power windows.
