Compare the2022 Porsche 911VS 2022 Chevrolet Corvette

The 911 (except GT3) has standard Warn and Brake Assist, 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 911 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Corvette doesn’t offer all-wheel drive.

A passive infrared night vision system optional on the 911 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Corvette doesn’t offer a night vision system.

The 911’s optional 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. The Corvette doesn’t offer a lane departure warning system.

The 911 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Corvette only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

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

The 911 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 or 14,000 miles sooner.

The 911’s corrosion warranty is 6 years and unlimited miles longer than the Corvette’s (12/unlimited vs. 6/100,000).

For smoother operation, better efficiency and fewer moving parts, the engines in the 911 have an overhead cam design, rather than the old pushrod design of the engines in the Corvette.

J.D. Power ranks Porsche second in reliability, above the industry average. With 29 more problems per 100 vehicles, Chevrolet is ranked 12th.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Porsche vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Porsche 8 places higher in reliability than Chevrolet.

The 911 has more powerful engines than the Corvette:

As tested in Motor Trend the 911 S 3.0 turbo 6-cylinder is faster than the Corvette Z51 (automatics tested):

In a Motor Trend race course test, the Porsche 911 Turbo S Coupe was clocked 4.86 seconds faster than the Chevrolet Corvette Coupe (92.97 sec. vs. 97.83 sec.).

The flat cylinder configuration of the boxer engine in the 911 lowers its center of gravity, enhancing handling stability. The Corvette doesn’t offer a boxer engine configuration.

On the EPA test cycle the 911 Coupe gets better mileage than the Corvette:

On the EPA test cycle the 911 Cabriolet gets better mileage than the Corvette:

In heavy traffic or at stop lights the 911’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Corvette doesn’t offer an automatic engine start/stop system.

The 911’s optional fuel tank has 5.2 gallons more fuel capacity than the Corvette (23.7 vs. 18.5 gallons).

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Porsche 911 higher (5 out of 10) than the Chevrolet Corvette (3). This means the 911 produces up to 16.5 pounds less smog-producing pollutants than the Corvette every 15,000 miles.

All wheel drive, available in the 911, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Chevrolet Corvette is not available with all wheel drive.

For better stopping power the 911’s front brake rotors are larger than those on the Corvette:

The 911 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 911 stops much shorter than the Corvette:

For better traction, the 911 Turbo S/GT3’s tires are larger than the largest tires available on the Corvette (F:255/35R20 & R:315/30R21 vs. F:245/35R19 & R:305/30R20).

For better ride, handling and brake cooling the 911 offers optional 20-inch front and 21-inch rear wheels. The Corvette’s largest wheels are only 19-inches in the front and 20-inches in the rear.

The 911 (except Base/GT3) offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Corvette doesn’t offer an active sway bar system.

The 911 GT3 handles at 1.15 G’s, while the Corvette Coupe pulls only 1.01 G’s of cornering force in a Motor Trend skidpad test.

The 911 GT3 executes Motor Trend’s “Figure Eight” maneuver 1.1 seconds quicker than the Corvette Coupe (22.3 seconds @ .95 average G’s vs. 23.4 seconds @ .86 average G’s).

For better maneuverability, the 911 GT3’s turning circle is 2.3 feet tighter than the Corvette with Magnetic Ride Control’s (34.1 feet vs. 36.4 feet). The 911’s turning circle is 1.3 feet tighter than the Corvette’s (36.8 feet vs. 38.1 feet).

The Porsche 911 may be more efficient, handle and accelerate better because it weighs up to about 400 pounds less than the Chevrolet Corvette.

The 911 is 4.4 inches shorter than the Corvette, making the 911 easier to handle, maneuver and park in tight spaces.

To almost totally eliminate engine vibration in the passenger area, the 911 Manual (except PDK) has an electronically controlled liquid-filled front engine mount. A computer-controlled electric current in the liquid changes its viscosity, allowing the mount to dampen the engine completely at all RPMs. The Corvette uses conventional solid rubber engine mounts.

The front grille of the 911 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Corvette doesn’t offer active grille shutters.

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

The 911 has standard seating for 4 passengers; the Corvette can only carry 2.

The 911 has 22 cubic feet more passenger volume than the Corvette (73 vs. 51).

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Chevrolet. J.D. Power ranks Porsche first in service department satisfaction. With a 48% lower rating, Chevrolet is ranked 19th.

The 911’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Corvette’s rear power window switches have to be held the entire time to open or close them fully.

The 911’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Corvette’s manually variable intermittent wipers have to be constantly adjusted.

To improve rear visibility by keeping the rear window clear, the 911 (except Cabriolet/GT3) offers an optional rear wiper. The Corvette doesn’t offer a rear wiper.

While driving with high beams on, sensitive light sensors available for the 911 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 911 offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Corvette doesn’t offer cornering lights.

To keep a safe, consistent following distance, the 911 (except Manual) 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.

The 911 (except Manual/GT3)’s optional Active Parking Support can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote ParkAssist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Corvette doesn’t offer an automated parking system.

Motor Trend performed a comparison test in its March 2021 issue and they ranked the Porsche 911 Turbo S Coupe two places higher than the Chevrolet Corvette Coupe.
