Tires and Wheels

For better traction, the RC F has larger tires than the AMG C 63 Coupe (F:255/35R19 & R:275/35R19 vs. F:245/35R19 & R:265/35R19).

The RC F’s tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the AMG C 63 Coupe’s standard 40 series front tires.

For better ride, handling and brake cooling the RC F has standard 19-inch wheels. Smaller 18-inch wheels are standard on the AMG C 63 Coupe.

The RC F has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the AMG C 63 Coupe; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

For better maneuverability, the RC F’s turning circle is 1.7 feet tighter than the AMG C 63 Coupe’s (35.4 feet vs. 37.1 feet).

Chassis

The RC F 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.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Mercedes. J.D. Power ranks Lexus third in service department satisfaction. With a 3% lower rating, Mercedes is ranked 6th.

Ergonomics

The RC F’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.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The RC F offers available headlight washers to keep headlight output high. The AMG C 63 Coupe doesn’t offer headlight washers.

On extremely cold winter days, the RC F’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The AMG C 63 Coupe doesn’t offer a heated steering wheel.
