Safety Comparison

The Cayman PDK offers optional Porsche Active Safety, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Corvette doesn't offer collision warning or crash mitigation brakes.

Both the Cayman and the Corvette have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, traction control and electronic stability systems to prevent skidding.

Warranty Comparison

The Cayman comes with a full 4 year/50,000 mile basic warranty, which covers the entire car and includes 24 hour roadside assistance. The Corvette’s 3 year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.

The Cayman’s corrosion warranty is 4 years and unlimited miles longer than the Corvette’s (10/unlimited vs. 6/100,000).

Reliability Comparison

For smoother operation, better efficiency and fewer moving parts, the engines in the Cayman have an overhead cam design, rather than the old pushrod design of the engines in the Corvette.

J.D. Power and Associates’ 2013 Initial Quality Study of new car owners surveyed provide the statistics that show that Porsche vehicles are better in initial quality than Chevrolet vehicles. J.D. Power ranks Porsche first in initial quality, above the industry average. With 17 more problems per 100 vehicles, Chevrolet is ranked fifth.

J.D. Power and Associates’ 2013 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Chevrolet vehicles. J.D. Power ranks Porsche second in reliability, above the industry average. With 31 more problems per 100 vehicles, Chevrolet is ranked 12th.

Engine Comparison

The flat cylinder configuration of the boxer engine in the Cayman lowers its center of gravity, enhancing handling stability. The Corvette doesn’t offer a boxer engine configuration.

Fuel Economy and Range Comparison

On the EPA test cycle the Cayman gets better fuel mileage than the Corvette:




21 city/30 hwy

17 city/29 hwy


20 city/28 hwy

17 city/29 hwy



22 city/32 hwy

16 city/28 hwy

16 city/28 hwy


Regenerative brakes improve the Cayman’s fuel efficiency by converting inertia back into energy instead of wasting it. The Corvette doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Cayman’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Corvette doesn’t offer an automatic engine start/stop system.

Brakes and Stopping Comparison

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




Front Rotors

13.8 inches

12.6 inches

13.6 inches

Rear Rotors

13.8 inches

13.3 inches

13.3 inches

The Cayman 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 Corvette doesn’t offer ceramic brake rotors.

The Cayman stops shorter than the Corvette:



60 to 0 MPH

101 feet

104 feet

Tires and Wheels Comparison

For better ride, handling and brake cooling the Cayman offers optional 20-inch wheels. The Corvette’s largest wheels are only 19-inches in the front and 20-inches in the rear.

Suspension and Handling Comparison

The front and rear suspension of the Cayman uses coil springs for better ride, handling and control than the Corvette, which uses transverse leafs springs. Coil springs compress more progressively and offer more suspension travel for a smoother ride with less bottoming out.

The Cayman handles at 1.06 G’s, while the Corvette Stingray Coupe pulls only 1.02 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the Cayman’s turning circle is 1.7 feet tighter than the Corvette’s (36 feet vs. 37.7 feet).

Chassis Comparison

The Porsche Cayman may be more efficient, handle and accelerate better because it weighs about 400 pounds less than the Chevrolet Corvette.

The Cayman is 4.5 inches shorter than the Corvette, making the Cayman easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver while at idle, the interior of the Cayman S is quieter than the Corvette Stingray Coupe (53 vs. 55 dB).

Cargo Capacity Comparison

A low lift-over trunk design makes loading and unloading the Cayman easier. The Cayman’s trunk lift-over height is 32.7 inches, while the Corvette’s liftover is 41.2 inches.

Ergonomics Comparison

If the windows are left down on the Cayman the driver can raise them all using the key in the outside lock cylinder; on a hot day the driver can lower the windows. The driver of the Corvette can only operate the windows from inside the vehicle, with the ignition on.

The Cayman’s optional wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Corvette’s manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the Cayman to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Corvette doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the Cayman offers an optional rear wiper. The Corvette doesn’t offer a rear wiper.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Cayman offers available headlight washers to keep headlight output high. The Corvette doesn’t offer headlight washers.

To help drivers see further while navigating curves, the Cayman offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Corvette doesn’t offer cornering lights.

The Cayman’s power mirror controls are mounted on the armrest for easy access. The Corvette’s power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.

To keep a safe, consistent following distance, the Cayman PDK offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Corvette doesn’t offer an adaptive cruise control.
