The Ford Shelby Mustang GT350 was a variant of the S-197 II Shelby Mustang that debuted for the 2011 model year. Built by Shelby from standard Mustangs and offered as a post-purchase upgrade, this new GT350 was released on the 45th anniversary of the release of the 1st Gen Shelby Mustang GT350. Offered in both coupe and convertible body styles, the GT350 was fitted with the 430hp naturally aspirated 5.0L 'Coyote' V8 engine, or more commonly with the supercharged version of the same Coyote engine that reached up to 624hp in output. Both manual and automatic transmission options were available, with drive being sent to the rear wheels. After approximately 414 samples were built, production of the S-197 II Ford Shelby Mustang GT350 ended in 2014, although the GT350 name would continue in the next generation of Shelby Mustang as the 3rd Gen Ford Shelby Mustang GT350.
