Based on the latest-generation Mustang, the all-new Shelby GT500 is the most powerful production Shelby model ever created. It also comes with the quickest acceleration and highest horsepower numbers ever offered on a street legal Ford Mustang with factory parts. Designed to offer supercar performance on an even higher level than the "base" Shelby GT350 Mustang, the new GT500 is also fitted with the quickest-shifting transmission ever offered on a Mustang. Under that long sculpted hood sits a hand-built 5.2-liter aluminum alloy V8 that's mildly based on the Shelby GT350s Voodoo engine, only in this case the flat-plane crankshaft has been replaced with a more traditional cross-plane design. The 760 horsepower and 625 lb-ft of torque are attainable thanks to a massive 2.65-liter roots-types supercharger with an air-to-liquid intercooler. Both the supercharger and the intercooler are integrated neatly inside the V of the engine for improved response and low-down torque. All that power is sent exclusively to the rear wheels through a Tremec dual-clutch transmission with 7 forward speeds that can shift gears in just under 100 milliseconds. As expected from a sports car of this caliber, there are various driving modes available, including normal, weather, sport, drag and track, not to mention a line-lock feature or launch control, all of them available through selectable Track Apps in Ford's uConnect infotainment system.
