Available as a coupe or a convertible, the Shelby possesses an intimidating 500 horsepower, 5.4 liter, V8 engine and comes standard with a 6-speed manual transmission. With only one powertrain combination available, this cars reason for being quickly becomes clear. Fuel economy is not the car's strong point, getting 15 mpg in the city and 21 mpg on the highway. Still, these numbers are relatively impressive given the car's power. This car still manages to provide modern amenities such as air-conditioning, a 6-disc CD changer and leather seats for 4 passengers. Safety is addressed with technical features such as 4-wheel Brembo disc brakes, traction control and an assortment of protective airbags. The 2008 model carries over from 2007.
