The Shelby GT500’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The 911 doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing safer, the Shelby GT500’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 911 doesn’t offer a cross-path warning system.

Both the Shelby GT500 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 and rearview cameras.

The Ford Shelby GT500 weighs 530 to 817 pounds more than the Porsche 911. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

Ford’s powertrain warranty covers the Shelby GT500 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 16 times as many Ford dealers as there are Porsche dealers, which makes it much easier should you ever need service under the Shelby GT500’s warranty.
