Safety

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 Corvette 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 Corvette’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 Corvette doesn't offer collision warning or crash mitigation brakes.

The AMG C 63 Coupe’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Corvette doesn’t offer a lane departure warning system.

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 Corvette only offers a rear monitor.

The AMG C 63 Coupe’s blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Corvette doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing safer, the AMG C 63 Coupe’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Corvette doesn’t offer a cross-path warning system.

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 Corvette doesn’t offer a driver alert monitor.

Both the AMG C 63 Coupe and the Corvette 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.

The Mercedes AMG C 63 Coupe weighs 438 to 836 pounds more than the Chevrolet Corvette. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Warranty

The AMG C 63 Coupe comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Corvette’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

The AMG C 63 Coupe’s corrosion warranty is unlimited miles longer than the Corvette’s (unlimited vs. 100,000 miles).

Reliability

For smoother operation, better efficiency and fewer moving parts, the engines in the AMG C 63 Coupe have an overhead cam design, rather than the old pushrod design of the engines in the Corvette.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Mercedes vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Mercedes 6 places higher in reliability than Chevrolet.

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 Corvette doesn’t offer an automatic engine start/stop system.

Environmental Friendliness

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 Chevrolet Corvette (1). This means the AMG C 63 Coupe produces up to 39 pounds less smog-producing pollutants than the Corvette every 15,000 miles.

Transmission

The Mercedes AMG C 63 Coupe comes standard with an automatic transmission, for driver comfort, especially in the city. Automatic costs extra on the Corvette.

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 Corvette.

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 Corvette doesn’t offer an SMG.

Brakes and Stopping

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

Suspension and Handling

The front and rear suspension of the AMG C 63 Coupe uses coil springs for better ride, handling and control than the Corvette, which uses transverse leafs springs. Coil springs compress more progressively and offer more suspension travel for a smoother ride with less bottoming out.

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 Corvette doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the AMG C 63 Coupe’s wheelbase is 5.1 inches longer than on the Corvette (111.8 inches vs. 106.7 inches).

For better handling and stability, the track (width between the wheels) on the AMG C 63 Coupe is 1 inch wider in the front and .5 inches wider in the rear than the average track on the Corvette.

For better maneuverability, the AMG C 63 Coupe’s turning circle is .6 feet tighter than the Corvette’s (37.1 feet vs. 37.7 feet).

Passenger Space

The AMG C 63 Coupe has standard seating for 4 passengers; the Corvette can only carry 2.

The AMG C 63 Coupe has 27.3 cubic feet more passenger volume than the Corvette (79.3 vs. 52).

Cargo Capacity

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 Corvette doesn’t offer a power or hands-free opening trunk.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Chevrolet. J.D. Power ranks Mercedes 6th in service department satisfaction (above the industry average). With a 19% lower rating, Chevrolet is ranked 10th.

Ergonomics

Unlike the driver-only memory system optional at extra cost in the Corvette, 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.

The AMG C 63 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. An easy entry system costs extra on the Corvette.

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 Corvette 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 Corvette’s manually variable intermittent wipers have to be constantly adjusted.

While driving with high beams on, sensitive light sensors available for the AMG C 63 Coupe detect other vehicles which could be blinded and automatically switch to low beams. The Corvette doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the AMG C 63 Coupe offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Corvette doesn’t offer cornering lights.

The AMG C 63 Coupe’s power mirror controls are mounted on the armrest for easy access. The Corvette’s power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.

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 Corvette 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 Corvette doesn’t offer an automated parking system.

Model Availability

The Mercedes AMG C 63 comes in coupe, convertible and sedan bodystyles; the Chevrolet Corvette isn’t available as a sedan.
