Shelby American has made its name tuning various Ford products, and now the Focus ST can be added to this list. Just introduced at the Detroit Auto Show, the Shelby Focus ST doesn't add any extra horsepower under the hood, but it should still make sizable gains in performance thanks to an upgraded suspension, brakes and exhaust systems. Also on hand at the Shelby display was a widebody version of the powerful Shelby GT500 Super Snake.
When Shelby first launched the GT500 Super Snake in 2007 (or relaunched, if you consider the one-off 1967 prototype), the 5.4-liter supercharged V8 was boosted all the way up to... wait for it... 600 horsepower. Fast-forward just five years and the muscle car landscape looks quite different. The 2013 Shelby GT500 now comes with 662 tire-shredding horsepower from the factory.
