Safety Comparison

The 718 Boxster PDK offers optional Porsche Active Safe, 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.

The 718 Boxster’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Corvette doesn’t offer a system to reveal objects in the driver’s blind spots.

Both the 718 Boxster and the Corvette 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, daytime running lights and rearview cameras.

Warranty Comparison

The 718 Boxster 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 718 Boxster’s corrosion warranty is 6 years and unlimited miles longer than the Corvette’s (12/unlimited vs. 6/100,000).

Reliability Comparison

For smoother operation, better efficiency and fewer moving parts, the engines in the 718 Boxster have an overhead cam design, rather than the old pushrod design of the engines in the Corvette.

J.D. Power and Associates’ 2016 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 second in initial quality, above the industry average. With 11 more problems per 100 vehicles, Chevrolet is ranked 6th.

J.D. Power and Associates’ 2016 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 28 more problems per 100 vehicles, Chevrolet is ranked 6th.

Engine Comparison

The flat cylinder configuration of the boxer engine in the 718 Boxster lowers its center of gravity, enhancing handling stability. The Corvette doesn’t offer a boxer engine configuration.

Regenerative brakes improve the 718 Boxster’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 718 Boxster’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.

Tires and Wheels Comparison

For better ride, handling and brake cooling the 718 Boxster 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 718 Boxster 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 718 Boxster S handles at 1.04 G’s, while the Corvette Stingray Convertible pulls only 1.00 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the 718 Boxster’s turning circle is 1.7 feet tighter than the Corvette’s (36 feet vs. 37.7 feet).

Chassis Comparison

The Porsche 718 Boxster may be more efficient, handle and accelerate better because it weighs about 350 to 550 pounds less than the Chevrolet Corvette.

The 718 Boxster is 4.5 inches shorter than the Corvette, making the 718 Boxster easier to handle, maneuver and park in tight spaces.

As tested by Car and Driver while at idle, the interior of the 718 Boxster S is quieter than the Corvette Stingray Convertible (54 vs. 55 dB).

Ergonomics Comparison

If the windows are left down on the 718 Boxster 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.

In case of a sudden change of weather, the 718 Boxster has a standard remote convertible top that can be raised from a distance to protect the interior of the vehicle from damage. The Corvette’s top can only be opened by remote, so the driver will have to run to the car, get in, turn the ignition on and raise the top to prevent the interior from being damaged.

The 718 Boxster’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.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The 718 Boxster offers available headlight washers to keep headlight output high. The Corvette doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the 718 Boxster detect other vehicles which could be blinded and automatically switch to low beams. The Corvette doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the 718 Boxster 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 718 Boxster’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.

On extremely cold Winter days, the 718 Boxster’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Corvette doesn’t offer a heated steering wheel.

To keep a safe, consistent following distance, the 718 Boxster 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.

Economic Advantages Comparison

Insurance will cost less for the 718 Boxster owner. The Complete Car Cost Guide estimates that insurance for the 718 Boxster will cost $140 less than the Corvette over a five-year period.

The 718 Boxster will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the 718 Boxster will retain 52.99% to 56.75% of its original price after five years, while the Corvette only retains 7.38% to 57.63%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Porsche 718 Boxster will be $1850 to $10,000 less than for the Chevrolet Corvette.
