Safety Comparison

For enhanced safety, the front seat shoulder belts of the Chevrolet Corvette are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Porsche Cayman doesn’t offer height-adjustable seat belts.

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, head airbags, front seatbelt pretensioners, 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 Porsche covers the Cayman. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 100,000 miles. Coverage on the Cayman ends after only 4 years or 50,000 miles.

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

Reliability Comparison

The Corvette has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The Cayman doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without their vehicle while it’s being repaired. Consumer Reports predicts that the Chevrolet Corvette Z06’s reliability will be 26% better than 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:205/55R17 & R:235/50R17). The Corvette ZR1’s tires are larger than the largest tires available on the Cayman (F:285/30R19 & R:335/25R20 vs. F:235/35R19 & R:305/30R19).

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 55 series front and 50 series rear tires. The Corvette ZR1’s 285/30R19 front and 335/25R20 rear tires have a lower 30 series front and 25 series rear profile than the Cayman’s optional 35 series front and 30 series rear tires.

For better ride, handling and brake cooling the Corvette has standard 18-inch front and 19-inch rear wheels. Smaller 17-inch wheels are standard on the Cayman. The Corvette ZR1’s 20-inch rear wheels are larger than the 19-inch wheels optional 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

The Corvette has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Cayman doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the Corvette’s wheelbase is 10.6 inches longer than on the Cayman (105.7 inches vs. 95.1 inches).

For better handling and stability, the average track (width between the wheels) on the Corvette is 4.2 inches wider in the front and 1.3 inches wider in the rear than the average track on the Cayman.

The Corvette’s front to rear weight distribution is more even (49.9% to 50.1%) than the Cayman’s (58% to 42%). This gives the Corvette more stable handling and braking.

The Corvette ZR1 handles at 1.10 G’s, while the Cayman pulls only .90 G’s of cornering force in a Road & Track skidpad test.

The Corvette ZR1 goes through Road & Track’s slalom 5 MPH faster than the Cayman (74.9 vs. 69.9 MPH).

The Corvette Z06 performs Car and Driver’s emergency lane change maneuver 6.8 MPH faster than the Cayman S (70.7 vs. 63.9 MPH).

The Corvette ZR1 executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the Cayman S (23.1 seconds vs. 24.5 seconds).

Chassis Comparison

Passenger Space Comparison

The Corvette has 4.1 cubic feet more passenger volume than the Cayman (52.1 vs. 48).

The Corvette has .1 inches more front legroom, .4 inches more front hip room and 3.7 inches more front shoulder room than the Cayman.

Cargo Capacity Comparison

The Corvette Coupe has a much larger trunk than the Cayman (22.4 vs. 14.5 cubic feet).

Ergonomics Comparison

The Corvette’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Cayman doesn’t offer an easy entry 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 Cayman does not have an oil pressure gauge.

The Corvette offers an optional heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The Cayman doesn’t offer a heads-up display.

Keyless Access standard on the Corvette allows the driver to unlock the doors, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the car in bad weather or making a hurried start to your trip. The Porsche Cayman doesn’t offer an advanced key system.

The Corvette has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. When the ignition turns off, the headlights turn off after a delay timed to allow you to securely get to your front door. The Cayman doesn’t offer automatic headlights.

The Corvette’s sun-visors swivel front-to-side to block glare from the side windows. The Cayman’s visors are fixed into the windshield header.

The Corvette’s 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. The Cayman doesn’t offer dual zone air conditioning.
