An engine control system that can shut down some of the engine’s cylinders helps improve the Corvette 6.7 V8’s fuel efficiency. The 911 doesn’t offer a system that can shut down part of the engine.

The Corvette has 1.9 gallons more fuel capacity than the 911’s standard fuel tank (18.5 vs. 16.6 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.

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 Z06/Grand Sport/ZR1’s tires are larger than the largest tires available on the 911 (F:275/30R20 & R:345/25R21 vs. F:255/35R20 & R:325/30R21).

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’s standard 40 series front and 35 series rear tires. The Corvette Z06/Grand Sport/ZR1’s 275/30R20 front and 345/25R21 rear tires have a lower 30 series front and 25 series rear profile than the 911’s optional 35 series front and 30 series rear 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 Grand Sport X’s wheelbase is 10.5 inches longer than on the 911 (107 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).

The Corvette Z06 Z07 Coupe handles at 1.16 G’s, while the 911 Carrera 4 GTS Coupe pulls only 1.03 G’s of cornering force in a Car and Driver skidpad test.

The Corvette ZR1X Convertible handles at 1.14 G’s, while the 911 S Cabriolet pulls only 1.02 G’s of cornering force in a Motor Trend skidpad test.

The Corvette ZR1 ZTK Coupe executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the 911 Carrera T Coupe (21.6 seconds @ 1.1 average G’s vs. 23.4 seconds @ .87 average G’s).

The Corvette ZR1X Convertible executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the 911 S Cabriolet (21.9 seconds @ 1.08 average G’s vs. 23.2 seconds @ .9 average G’s).

Servicing Ease

The Corvette offers an optional 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.

The Corvette’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The 911’s cruise control switches are unlit, making them difficult to find at night and operate safely.

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.

The Chevrolet Corvette stands out above the Porsche 911 by offering not one, but two Qi-compatible phone chargers. This convenience helps travelers with multiple devices to keep powered up on-the-go. Wireless charging eliminates lost or cluttered charging cables and two of them provide more flexibility.
