Safety Comparison

The Corvette has standard OnStar ®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The 911 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Corvette and the 911 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, electronic stability systems to prevent skidding and daytime running lights.

Warranty Comparison

Chevrolet’s powertrain warranty covers the Corvette 1 year and 10,000 miles longer than Porsche covers the 911. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the 911 ends after only 4 years or 50,000 miles.

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. Porsche doesn’t pay scheduled maintenance for the 911.

There are over 21 times as many Chevrolet dealers as there are Porsche dealers, which makes it much easier should you ever need service under the Corvette’s warranty.

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 911 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 911 requires premium, which can cost 20 to 55 cents more per gallon.

The Corvette has 1.6 gallons more fuel capacity than the 911 RWD/Turbo/GT3’s standard fuel tank (18.5 vs. 16.9 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 911 doesn’t offer a cap-less fueling system.

Tires and Wheels Comparison

For better traction, the Corvette has larger front standard tires than the 911 (F:245/40R18 & R:285/35R19 vs. F:235/40R19 & R:285/35R19). The Corvette Z06’s tires are larger than the largest tires available on the 911 (F:285/30R19 & R:335/25R20 vs. F:245/35R20 & R:305/30R20).

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 911’s optional 35 series front and 30 series rear 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 911 doesn’t offer run-flat tires.

Suspension and Handling Comparison

For a smoother ride and more stable handling, the Corvette’s wheelbase is 10.2 inches longer than on the 911 (106.7 inches vs. 96.5 inches). The Corvette’s wheelbase is 10 inches longer than on the 911 GT3 Coupe (106.7 feet vs. 96.7 inches).

For better handling and stability, the average track (width between the wheels) on the Corvette is 2.8 inches wider in the front and 1.6 inches wider in the rear than the average track on the 911.

The Corvette’s front to rear weight distribution is more even (50% to 50%) than the 911’s (39.3% to 60.7%). This gives the Corvette more stable handling and braking.

The Corvette Z06 Coupe handles at 1.19 G’s, while the 911 Coupe pulls only .98 G’s of cornering force in a Car and Driver skidpad test.

The Corvette Z06 Convertible handles at 1.14 G’s, while the 911 S Cabriolet pulls only 1.03 G’s of cornering force in a Car and Driver skidpad test.

The Corvette Z06 Coupe executes Motor Trend’s “Figure Eight” maneuver 2.1 seconds quicker than the 911 S Coupe Carrera 4 (22.3 seconds @ 1.06 average G’s vs. 24.4 seconds @ 1.06 average G’s).

Chassis Comparison

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 911 (.29 to .33). A more efficient exterior helps the Corvette go faster and keeps the interior quieter. It also helps the Corvette get better fuel mileage.

As tested by Car and Driver, the interior of the Corvette Stingray Coupe is quieter than the 911 GT3 Coupe:



At idle

55 dB

59 dB


91 dB

94 dB

70 MPH Cruising

69 dB

77 dB

As tested by Car and Driver while under full throttle, the interior of the Corvette Stingray Convertible is quieter than the 911 S Cabriolet (90 vs. 91 dB).

Cargo Capacity Comparison

The Corvette Coupe has a much larger trunk than the 911 Coupe with its rear seat up (15 vs. 5.1 cubic feet). The Corvette has a much larger trunk with its rear seat folded than the 911 Coupe with its rear seat folded (15 vs. 9.2 cubic feet).

The Corvette Convertible has a much larger trunk with its top down than the 911 Cabriolet (10 vs. 4.8 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 911 doesn’t offer a remote starting system.

The Corvette offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The 911 doesn’t offer a heads-up display.

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 911 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 $4325 less than the 911 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 $24973 to $83083 less than for the Porsche 911.
