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.

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.

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

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.

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 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.

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).

The Corvette Z06 Z07 Coupe handles at 1.16 G’s, while the 911 Carrera 4 GTS pulls only 1.03 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).

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.

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.

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.
