Using vehicle speed sensors, smart airbags in the Corvette deploy with different levels of force to help better protect passengers of all sizes in different collisions. The 911 Turbo S’ airbags don’t have smart features and will always deploy full force.
The Chevrolet Corvette has Daytime Running Lights to help keep it more visible under all conditions. Daytime Running Lights decrease the chances of collisions. Canadian government studies show that driving with lights during the day reduces accidents by 11% by making vehicles more conspicuous. The 911 Turbo S doesn’t offer Daytime Running Lights.
The Corvette offers optional OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The 911 Turbo S doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies.
Both the Corvette and the 911 Turbo S have standard driver and passenger frontal airbags, front seatbelt pretensioners, four wheel antilock brakes, electronic stability systems to prevent skidding, available front and rear side-impact airbags and head airbags.
There are almost 22 times as many Chevrolet dealers as there are Porsche dealers, which makes it much easier to get service under the Corvette’s warranty.
The Corvette has 1.4 gallons more fuel capacity than the 911 Turbo S (18 vs. 16.6 gallons), for longer range between fill-ups.
For better traction, the Corvette has larger front tires than the 911 Turbo S (245/40R18 vs. 225/40R18).
For better ride, handling and brake cooling the Corvette has standard 19 inch rear wheels. Only 18 inch wheels are available on the 911 Turbo S.
The Corvette has a standard tire pressure monitoring system, which will alert the driver to a drop in tire pressure before damage to the tire or an accident might occur. The 911 Turbo S doesn’t offer a low tire pressure warning system.
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 Turbo S doesn’t offer run-flat tires.
The Corvette offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The 911 Turbo S’ suspension doesn’t offer adjustable shock absorbers.
For a smoother ride and more stable handling, the Corvette’s wheelbase is 1 foot, 1.2 inches longer than on the 911 Turbo S (105.7 vs. 92.5 inches).
For better handling and stability, the track (width between the wheels) on the Corvette is 4.1 inches wider in the front and .5 inches wider in the rear than on the 911 Turbo S.
The Corvette’s front to rear weight distribution is more even (51% to 49%) than the 911 Turbo S’ (40% to 60%). This gives the Corvette more stable handling and braking.
The Corvette Coupe handles at .98 G’s, while the 911 Turbo S Turbo pulls only .93 G’s of cornering force in a Car and Driver skidpad test.
The Chevrolet Corvette may be more efficient, handle and accelerate better because it weighs about 350 to 550 pounds less than the Porsche 911 Turbo S.
The design of the Chevrolet Corvette amounts to more than styling. The Corvette has an aerodynamic coefficient of drag of .28 Cd. That is lower than the 911 Turbo S (.31). A more efficient exterior helps the Corvette go faster and keeps the interior quieter. It also helps the Corvette get better fuel mileage.
The Corvette has 1.4 inches more front legroom, .3 inches more front hip room and 3.5 inches more front shoulder room than the 911 Turbo S.
The Corvette Coupe has a much larger trunk than the 911 Turbo S with its rear seat up (22.4 vs. 4.6 cubic feet). The Corvette has a much larger trunk with its rear seat folded than the 911 Turbo S with its rear seat folded (22.4 vs. 11.7 cubic feet).
The Corvette Convertible has a larger trunk with its top up than the 911 Turbo S Cabriolet with its top up (10.5 vs. 11.7 cubic feet).
The Corvette’s standard tilting steering column adjusts to different sized drivers and makes entering and exiting easier. Porsche doesn’t offer tilt steering on the 911 Turbo S.
The Corvette offers an optional heads-up display which projects speed and other key instrumentation readouts onto the windshield, allowing drivers to view information without diverting their eyes from the road. The 911 Turbo S doesn’t offer a heads-up display.
The Corvette’s standard power window controls are mounted on the armrest for easy access. The 911 Turbo S’ available power window controls are spread out on the center console where they can’t be seen without the driver completely removing his eyes from the road.
The 911 Turbo S’ standard power locks don’t automatically lock the doors. The Corvette’s standard doors lock when the ignition is turned on. This is an important feature for occupant safety. Locked doors are proven to open less often in collisions, and they are also effective in preventing crime at traffic lights. (The power lock’s automatic feature may have to be activated by your dealer.)
The Corvette has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The 911 Turbo S doesn’t offer automatic headlights.
The Corvette’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The 911 Turbo S doesn’t offer dual zone air conditioning.
With optional voice command, the Corvette offers the driver hands free control of the navigation computer by simply speaking. The 911 Turbo S doesn’t offer a voice control system.
