Ford Shelby GT500

The Shelby Mustang is a high performance variant of the Ford Mustang which was built by Shelby American from 1965 through 1970. Following the introduction of the fifth generation Ford Mustang, the Shelby nameplate was revived in 2007 for new high performance versions of the Mustang.

For 1967, the GT 350 carried over the K-Code high performance 289 with a 'COBRA' aluminum hi-rise. The GT 500 was added to the lineup, equipped with the 428 Police Interceptor. These later cars carried over few of the performance modifications of the 1965–66 GT350s, although they did feature more cosmetic changes.

In September 1967, production was moved to the A.O. Smith Company of Ionia, Michigan, under Ford control. Shelby American had substantially less involvement after this time.

For 1968, the Cobra name was applied to both models, and they were now marketed as the Shelby Cobra GT 350 and the Shelby Cobra GT 500. In February 1968, the Cobra GT 500-KR "King of the Road" debuted; under the hood was a 428 cubic-inch Cobra Jet V8 which was rated at 335 horsepower (250 kW).

 Shelby and Ford returned for the 2007 model year with the Shelby GT500. Introduced at the 2003 New York International Auto Show, the GT500 uses a 5.4 L (330 CID) Modular 500 hp (370 kW) supercharged V8. Features include the Tremec TR-6060 6-speed manual transmission, suspension tuning, a body kit, and 18 inch wheels.

Deliveries of the Shelby GT500 began in May 2006.

A collaboration of Ford's Special Vehicle Team (SVT) and Carroll Shelby, the GT500 was produced in limited quantity for three years (approximately 10,000 units per year) on the line at Ford's Flat Rock, Michigan (AutoAlliance) assembly facility.

Ford's Special Vehicle Team (SVT) also released a small series (687 units) of GT500 using the S/C from Saleen. These cars had the 5.4L engine and were equipped with a 3.55:1 final drive. The GT500 has 500 hp (373 kW) @ 6000 rpm and 480 lb·ft (650 N·m) of torque @ 4500 rpm.

Starting in 2008, previous 2007 Shelby GT500 Mustangs could be sent to Carroll Shelby's Special Performance Plant in Las Vegas Nevada to be rebuilt into a Super Snake, for an additional cost of $27,995. The Super Snake will offer a 605 hp (451 kW) (at the engine) 5.4 L. A Kenne Bell twin-screw supercharged version with "over 725 hp" will also be available, without warranty and offer a 0–60 mph runs in 3.5 to 3.7 seconds. The Super Snake is inspired by the 1967 GT500 Super Snake, a car made by Carroll Shelby for Goodyear Tires.

The Super Snake also comes with a variety of other performance, handling and cosmetic changes including badging, gauge pod, 20" Alcoa wheels, fibreglass ram-air Super Snake hood, stripes, carbon fiber front splitter and skirts, larger 6-piston Baer brakes, front and rear brake cooling ducts, complete track setup suspension, aluminum driveshaft, 3.73 differential gears and cat-back exhaust system.

For the 2010 model year, the Shelby Mustang GT500 was redesigned along with the base Ford Mustang. As with the 2007–09 GT500, the 2010 includes unique front and rear fascias, hood with functional vents and unique rear spoiler. The rear spoiler includes a functional Gurney flap. Along with new exterior colors, customers have the option of extending the exterior stripes onto the seats. Production was limited to 2000 units.
The 5.4 L engines's power output was increased to 540 horsepower (403 kW) and 510 lb·ft (690 N·m) of torque with the addition of a cold air intake similar to the 08/09 GT500KR and includes a knock sensor to protect the engine if lower octane fuel is used. The 2010 GT500's fuel efficiency increased by 2 miles per gallon.
SVT re-tuned the coupe's suspension and worked with Goodyear on 19" tires with new construction, compound and tread pattern. The coupe's 19" wheels are forged for a reduction in unsprung weight. The convertible retained the 18" wheels offered on the 2007–09 GT500.
