Safety

Both the Corvette and the M8 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

Chevrolet’s powertrain warranty covers the Corvette 1 year and 10,000 miles longer than BMW covers the M8. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the M8 ends after only 4 years or 50,000 miles.

There are almost 9 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.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the Corvette (except ZR1)’s fuel efficiency. The M8 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 M8 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 M8 doesn’t offer a cap-less fueling system.

Transmission

The Corvette offers a manual transmission for better acceleration, control and fuel economy. The M8 doesn’t offer a manual transmission.

Tires and Wheels

For better traction, the Corvette Z06/Grand Sport/ZR1’s tires are larger than the largest tires available on the M8 (F:285/30R19 & R:335/25R20 vs. F:275/35R20 & R:285/35R20).

The Corvette’s standard 285/30R20 rear tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the M8’s standard 35 series tires. The Corvette Z06/Grand Sport/ZR1’s 285/30R19 front and 335/25R20 rear tires have a lower 30 series front and 25 series rear profile than the M8’s 35 series tires.

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 M8 doesn’t offer run-flat tires.

Suspension and Handling

For better maneuverability, the Corvette’s turning circle is 1.3 feet tighter than the M8’s (37.7 feet vs. 39 feet).

Chassis

The Chevrolet Corvette may be more efficient, handle and accelerate better because it weighs about 900 to 1000 pounds less than the BMW M8.

The Corvette is 1 foot, 2.3 inches shorter than the M8, making the Corvette easier to handle, maneuver and park in tight spaces.

The design of the Chevrolet Corvette amounts to more than styling. The Corvette has an aerodynamic coefficient of drag of .29 Cd. That is significantly lower than the M8 (.33). A more efficient exterior helps the Corvette go faster and keeps the interior quieter. It also helps the Corvette get better fuel mileage.

Recommendations

The Corvette was chosen as one of Car and Driver’s “Top Ten” for 15 of the last 22 years. The M8 has never been a Car and Driver “Top Ten” pick.

The Corvette was selected by Automobile Magazine as their 2014 Car of the Year. The M8 has never been chosen.

A group of representative automotive journalists from North America selected the Corvette as the 2014 North American Car of the Year. The M8 has never been chosen.
