For 2011 the Shelby GT500 is powered by a 550-hp 5.4L V8 with 510 lb-ft. of torque. IN addition to the increased horsepower, the new engine is 102 pounds lighter than previous cast-iron engine. The new lighter engine improves fuel economy (15 city/ 23 highway), therefore the gas guzzler tax has now been eliminated.
"The SVT team continues to push the performance standards of the Shelby to even higher levels and better refinement," said Jost Capito, director of global performance vehicles and motorsports business development. "All the changes we made reflect a desire for even better handling and outstanding driving dynamics - from weight savings to improved balance."
The addition of Electric Power Assist Steering (EPAS), a new optional SVT Performance Package, enhanced convertible rigidity and a lowered ride height contribute to improved driving dynamics and handling.
