Safety Comparison

Both the Corvette and the 6 Series 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 BMW covers the 6 Series. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 100,000 miles. Coverage on the 6 Series ends after only 4 years or 50,000 miles.

There are over 12 times as many Chevrolet dealers as there are BMW dealers, which makes it much easier should you ever need service under the Corvette’s warranty.

Reliability Comparison

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 BMW vehicles. J.D. Power ranks Chevrolet 6th in initial quality, above the industry average. With 2 more problems per 100 vehicles, BMW is ranked 8th.

Fuel Economy and Range Comparison

An engine control system that can shut down half of the engine’s cylinders helps improve the Corvette’s fuel efficiency. The 6 Series 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 6 Series requires premium, which can cost 20 to 55 cents more per gallon.

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 6 Series doesn’t offer a cap-less fueling system.

Brakes and Stopping Comparison

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 6 Series doesn’t offer ceramic brake rotors.

The Corvette stops much shorter than the 6 Series:

Tires and Wheels Comparison

For better traction, the Corvette Z06’s tires are larger than the largest tires available on the 6 Series (F:285/30R19 & R:335/25R20 vs. F:265/40R19 & R:295/35R19).

The Corvette’s standard 245/40R18 front and 285/35R19 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the 640i’s standard 45 series tires. The Corvette Z06’s 285/30R19 front and 335/25R20 rear tires have a lower 30 series front and 25 series rear profile than the 6 Series’ 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 640i.

Suspension and Handling Comparison

The Corvette Stingray Coupe handles at 1.07 G’s, while the 650i Coupe pulls only .94 G’s of cornering force in a Road & Track skidpad test.

The Corvette Stingray Convertible handles at 1.00 G’s, while the 650i Convertible pulls only .89 G’s of cornering force in a Car and Driver skidpad test.

The Corvette Stingray Coupe executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the 650i Coupe (23.7 seconds vs. 25.3 seconds).

For better maneuverability, the Corvette’s turning circle is .7 feet tighter than the 6 Series’ (37.7 feet vs. 38.4 feet).

Chassis Comparison

The Chevrolet Corvette may be more efficient, handle and accelerate better because it weighs about 700 to 1150 pounds less than the BMW 6 Series.

The Corvette is 1 foot, 3.9 inches shorter than the 6 Series, making the Corvette easier to handle, maneuver and park in tight spaces. The Corvette is 1 foot, 4.1 inches shorter than the M6 Convertible.

The design of the Chevrolet Corvette amounts to more than styling. The Corvette has an aerodynamic coefficient of drag of .29 Cd. That is lower than the 6 Series (.3 to .32). A more efficient exterior helps the Corvette go faster and keeps the interior quieter. It also helps the Corvette get better fuel mileage.

Cargo Capacity Comparison

The Corvette Coupe has a much larger trunk than the 6 Series Coupe (15 vs. 13 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 6 Series 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 6 Series has neither an oil pressure gauge nor a temperature gauge.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Corvette has standard extendable sun visors. The 6 Series doesn’t offer extendable visors.

Economic Advantages Comparison

Insurance will cost less for the Corvette owner. The Complete Car Cost Guide estimates that insurance for the Corvette will cost $3665 to $8330 less than the 6 Series over a five-year period.

The Corvette will cost the buyer less in the long run because of its superior resale value. The Intellichoice estimates that the Corvette will retain 50.94% to 52.8% of its original price after five years, while the 6 Series only retains 37.12% to 41.21%.

Intellichoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Chevrolet Corvette will be $21658 to $61930 less than for the BMW 6 Series.
