Safety Comparison

Both the Corvette and the C63 Coupe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

Chevrolet’s powertrain warranty covers the Corvette 1 year and 50,000 miles longer than Mercedes covers the C63 Coupe. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 100,000 miles. Coverage on the C63 Coupe ends after only 4 years or 50,000 miles.

The Corvette’s corrosion warranty is 2 years and 50,000 miles longer than the C63 Coupe’s (6/100,000 vs. 4/50,000).

Chevrolet pays for scheduled maintenance on the Corvette for 2 years and 24,000 miles. Chevrolet will pay for oil changes, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the C63 Coupe.

There are almost 14 times as many Chevrolet dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Corvette’s warranty.

Reliability Comparison

The battery on the Corvette is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the Corvette’s battery 20 to 30 degrees cooler, its life is increased by years. The C63 Coupe’s battery is in the hot engine compartment.

J.D. Power and Associates’ 2014 Initial Quality Study of new car owners surveyed provide the statistics that show that Chevrolet vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Chevrolet 6th in initial quality, above the industry average. With 9 more problems per 100 vehicles, Mercedes is ranked 13th.

Fuel Economy and Range Comparison

On the EPA test cycle the Corvette Auto with its standard engine gets better fuel mileage than the C63 Coupe with its standard engine (16 city/29 hwy vs. 13 city/19 hwy).

An engine control system that can shut down half of the engine’s cylinders helps improve the Corvette’s fuel efficiency. The C63 Coupe doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Chevrolet Corvette uses regular unleaded gasoline (premium recommended for maximum performance). The C63 Coupe requires premium, which can cost 20 to 55 cents more per gallon.

The Corvette has 1.1 gallons more fuel capacity than the C63 Coupe (18.5 vs. 17.4 gallons), for longer range between fill-ups.

The Corvette has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The C63 Coupe doesn’t offer a cap-less fueling system.

Brakes and Stopping Comparison

For better stopping power the Corvette Z06’s brake rotors are larger than those on the C63 Coupe:

C63 Coupe

Front Rotors

15.5 inches

14.2 inches

Rear Rotors

15.3 inches

13 inches

The Corvette Z06 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 C63 Coupe doesn’t offer ceramic brake rotors.

The Corvette stops much shorter than the C63 Coupe:

Tires and Wheels Comparison

For better traction, the Corvette has larger standard tires than the C63 Coupe (F:245/40R18 & R:285/35R19 vs. F:235/40R18 & R:255/35R18). The Corvette Z06’s tires are larger than the largest tires available on the C63 Coupe (F:285/30R19 & R:335/25R20 vs. F:235/40R18 & R:255/35R18).

The Corvette Z06’s 285/30R19 front and 335/25R20 rear tires provide better handling because they have a lower 30 series front and 25 series rear profile (height to width ratio) that provides a stiffer sidewall than the C63 Coupe’s optional 35 series front and 30 series rear tires.

For better ride, handling and brake cooling the Corvette has standard 19-inch rear wheels. Smaller 18-inch wheels are standard on the C63 Coupe. The Corvette’s optional 20-inch rear wheels are larger than the 19-inch wheels optional on the C63 Coupe.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the Corvette can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The C63 Coupe doesn’t offer run-flat tires.

Suspension and Handling Comparison

For better handling and stability, the track (width between the wheels) on the Corvette is 2 inches wider in the front and 1.7 inches wider in the rear than on the C63 Coupe.

The Corvette Stingray Coupe handles at 1.11 G’s, while the C63 Coupe pulls only .91 G’s of cornering force in a Motor Trend skidpad test.

The Corvette Stingray Coupe executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the C63 Coupe (23.7 seconds @ .83 average G’s vs. 25.2 seconds @ .78 average G’s).

Chassis Comparison

The Chevrolet Corvette may be more efficient, handle and accelerate better because it weighs about 450 to 500 pounds less than the Mercedes C63 Coupe.

The Corvette is 8.4 inches shorter than the C63 Coupe, making the Corvette easier to handle, maneuver and park in tight spaces.

Passenger Space Comparison

The Corvette has .9 inches more front headroom, 1.3 inches more front legroom and 1.2 inches more front shoulder room than the C63 Coupe.

Cargo Capacity Comparison

The Corvette Coupe has a much larger trunk than the C63 Coupe (15 vs. 11.7 cubic feet).

Ergonomics Comparison

The Corvette Auto offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The C63 Coupe doesn’t offer a remote starting system.

The Corvette’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 C63 Coupe does not have an oil pressure gauge.

The Corvette offers an optional heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The C63 Coupe doesn’t offer a heads-up display.

The Corvette’s optional air conditioned front seats cool the driver and front passenger and help take the sting out of hot leather in Summer. The C63 Coupe doesn’t offer air conditioned front seats.

Economic Advantages Comparison

Insurance will cost less for the Corvette owner. The Complete Car Cost Guide estimates that insurance for the Corvette will cost $5620 to $6770 less than the C63 Coupe over a five-year period.

Intellichoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Chevrolet Corvette will be $11996 to $17951 less than for the Mercedes C63 Coupe.
