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 Cayman 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 Cayman 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 and daytime running lights.

Warranty Comparison

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

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.

Reliability Comparison

The Cayman’s redline is at 7600 to 7800 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The Corvette has a 6500 to 6600 RPM redline.

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

The Corvette has 4.2 gallons more fuel capacity than the Cayman GT4’s standard fuel tank (18.5 vs. 14.3 gallons), for longer range between fill-ups. The Corvette has 1.6 gallons more fuel capacity than the Cayman’s standard fuel tank (18.5 vs. 16.9 gallons).

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 Cayman doesn’t offer a cap-less fueling system.

Brakes and Stopping Comparison

For better stopping power the Corvette’s standard brake rotors are larger than those on the Cayman:

Tires and Wheels Comparison

For better traction, the Corvette has larger standard tires than the Cayman (F:245/40R18 & R:285/35R19 vs. F:235/45R18 & R:265/45R18). The Corvette Z06’s tires are larger than the largest tires available on the Cayman (F:285/30R19 & R:335/25R20 vs. F:245/35R20 & R:295/30R20).

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 Cayman’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 Cayman GT4’s 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 Cayman.

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 Cayman doesn’t offer run-flat tires.

Suspension and Handling Comparison

For a smoother ride and more stable handling, the Corvette’s wheelbase is 9.3 inches longer than on the Cayman (106.7 inches vs. 97.4 inches).

For better handling and stability, the average track (width between the wheels) on the Corvette is 3.1 inches wider in the front and 1.6 inches wider in the rear than the average track on the Cayman.

The Corvette’s front to rear weight distribution is more even (50% to 50%) than the Cayman’s (45.1% to 54.9%). This gives the Corvette more stable handling and braking.

The Corvette Z06 Coupe handles at 1.19 G’s, while the Cayman S pulls only .99 G’s of cornering force in a Car and Driver skidpad test.

The Corvette Z06 Coupe executes Motor Trend’s “Figure Eight” maneuver 2 seconds quicker than the Cayman (22.3 seconds @ 1.06 average G’s vs. 24.3 seconds @ .8 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 Cayman (.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.

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

Passenger Space Comparison

The Corvette has 4 cubic feet more passenger volume than the Cayman (52 vs. 48).

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 Cayman 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 Cayman 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 Cayman doesn’t offer extendable visors.

The Corvette has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Cayman.

Economic Advantages Comparison

The Corvette will cost the buyer less in the long run because of its superior resale value. Kiplinger’s estimates that the Corvette will retain a greater percentage of its original price after three and five years than the Cayman.
