The Corvette’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the 911.

Both the Corvette and the 911 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, rearview cameras, available blind spot warning systems and rear cross-path warning.

Warranty

Chevrolet’s powertrain warranty covers the Corvette 1 year and 10,000 miles longer than Porsche covers the 911. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the 911 ends after only 4 years or 50,000 miles.

There are almost 15 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.

The Corvette can travel with zero emissions on a full charge for 5 miles. The 911 can’t move without running its internal combustion engine.

An engine control system that can shut down some of the engine’s cylinders helps improve the Corvette (except Z06/ZR1)’s fuel efficiency. The 911 doesn’t offer a system that can shut down part of the engine.

Regenerative brakes improve the Corvette E-Ray’s fuel efficiency by converting inertia back into energy instead of wasting it. The 911 doesn’t offer a regenerative braking system.

The Corvette has 1.6 gallons more fuel capacity than the 911’s standard fuel tank (18.5 vs. 16.9 gallons), for longer range between fill-ups.

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

Brakes and Stopping

The Corvette stops much shorter than the 911:

	Corvette	911
100 to 0 MPH	274 feet	332 feet	Car and Driver
70 to 0 MPH	139 feet	162 feet	Car and Driver
60 to 0 MPH	95 feet	99 feet	Motor Trend

Tires and Wheels

For better traction, the Corvette has larger standard tires than the 911 (F:245/35R19 & R:305/30R20 vs. F:235/40R19 & R:295/35R20).

The Corvette’s standard 245/35R19 front and 305/30R20 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the 911 Dakar’s standard 45 series front and 40 series rear tires. The Corvette Z06/E-Ray/ZR1’s 345/25R21 rear tires have a lower 25 series profile than the 911 GT3 RS’ optional 30 series tires.

The Corvette has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The 911 doesn’t offer vehicle monitored tire inflation.

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 911 doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the Corvette’s wheelbase is 10.7 inches longer than on the 911 (107.2 inches vs. 96.5 inches). The Corvette’s wheelbase is 10.5 inches longer than on the 911 GT3 (107.2 inches vs. 96.7 inches).

For better handling and stability, the average track (width between the wheels) on the Corvette is 2.9 inches wider in the front and 2.7 inches wider in the rear than the average track on the 911.

The Corvette Z06 Z07 Coupe handles at 1.16 G’s, while the 911 Dakar pulls only .96 G’s of cornering force in a Car and Driver skidpad test.

The Corvette Z06 Z07 Coupe executes Motor Trend’s “Figure Eight” maneuver 1.4 seconds quicker than the 911 S Coupe (21.9 seconds @ .99 average G’s vs. 23.3 seconds @ .86 average G’s).

Chassis

The Corvette’s standard power retractable hardtop allows a seamless transition from an open car, to a completely sealed coupe. The 911 doesn’t offer a retractable hardtop.

The Corvette uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The 911 doesn’t offer active noise cancellation.

As tested by Car and Driver, the interior of the Corvette Coupe is quieter than the 911 GT3:

	Corvette	911
At idle	47 dB	59 dB
Full-Throttle	92 dB	101 dB
70 MPH Cruising	74 dB	79 dB

Passenger Space

The Corvette has .6 inches more front legroom and 1.8 inches more front shoulder room than the 911.

Cargo Capacity

The Corvette Coupe has a much larger trunk than the 911 Coupe with its rear seat up (12.6 vs. 4.6 cubic feet).

The Corvette Convertible has a much larger trunk with its top down than the 911 Cabriolet with its top down (12.6 vs. 4.6 cubic feet). The Corvette Convertible has a much larger trunk than the 911 Cabriolet with its top up (12.6 vs. 10.4 cubic feet).

Servicing Ease

The Corvette has a standard under hood light to help in making nighttime maintenance checks, adding fluids, etc. The 911 doesn’t offer an under hood light.

Ergonomics

The Corvette has a standard 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 911 doesn’t offer a remote starting system.

Unlike the driver-only memory system optional in the 911, the Corvette offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, suspension setting and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Corvette offers an optional heads-up display that projects speed, tachometer, turn signal and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The 911 doesn’t offer a heads-up display.

On a hot day the Corvette’s driver can lower all the windows from a distance using the keyless remote. The driver of the 911 can only operate the windows from inside the vehicle, with the ignition on.

On a hot day the Corvette has a standard remote opening feature, to lower the top from outside. The 911 doesn’t offer a remote top, so the driver will have to enter the car, turn the ignition on and lower the top.

The Corvette has standard Keyless Open and Start that allows you to unlock the doors from either outside door handle, open the trunk, and start the engine, all without removing the key from the pocket or purse. The 911 GT3 doesn’t offer Comfort Access.

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 911 doesn’t offer extendable visors.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Chevrolet Corvette offers an optional wireless phone charging system (Qi) in the front center console. The 911 doesn’t offer wireless personal charging.

Economic Advantages

Insurance will cost less for the Corvette owner. The Complete Car Cost Guide estimates that insurance for the Corvette will cost $7325 to $17790 less than the 911 over a five-year period.

The Corvette will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Corvette will retain 67.13% to 70.13% of its original price after five years, while the 911 only retains 57.8% to 64.01%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Chevrolet Corvette will be $36160 to $1762113 less than for the Porsche 911.
