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 Boxster 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 Boxster 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 Boxster 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 Boxster. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 100,000 miles. Coverage on the Boxster 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 Boxster doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

Tires and Wheels Comparison

For better traction, the Corvette has larger standard tires than the Boxster (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 Boxster (F:285/30R19 & R:335/25R20 vs. F:235/40R18 & R:265/40R18).

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 Boxster’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 Boxster’s optional 35 series 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 Boxster. The Corvette ZR1’s 20-inch rear wheels are larger than the 19-inch wheels optional on the Boxster.

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 Boxster doesn’t offer run-flat tires.

Suspension and Handling Comparison

For a smoother ride and more stable handling, the Corvette’s wheelbase is 10.6 inches longer than on the Boxster (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 Boxster.

The Corvette’s front to rear weight distribution is more even (49.9% to 50.1%) than the Boxster’s (47% to 53%). This gives the Corvette more stable handling and braking.

The Corvette Convertible handles at .95 G’s, while the Boxster S pulls only .94 G’s of cornering force in a Car and Driver skidpad test.

Chassis Comparison

As tested by Car and Driver while under full throttle, the interior of the Corvette Convertible is quieter than the Boxster S (84 vs. 85 dB).

Passenger Space Comparison

The Corvette has 4.1 cubic feet more passenger volume than the Boxster (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 Boxster.

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 Boxster 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 Boxster 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 Boxster doesn’t offer a heads-up display.

Consumer Reports rated the Corvette’s headlight performance “Very Good,” a higher rating than the Boxster’s headlights, which were rated “Good.”

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 Boxster doesn’t offer automatic headlights.

The Corvette’s sun-visors swivel front-to-side to block glare from the side windows. The Boxster’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 Boxster doesn’t offer dual zone air conditioning.
