The Ford Mustang SVO was a limited-production variant of the third generation Ford Mustang produced from 1984 to 1986. Unlike its predecessor the Mustang Cobra, the SVO was designed differently than most mainstream Mustang models. The SVO was designed by Ford's Special Vehicle Operations (SVO) Department, hence the "SVO" nameplate. Like its predecessor, the Mustang Cobra, the SVO was also a liftback design. Unlike many other performance-oriented Mustangs, the SVO was powered by a 2.3L turbocharged Lima inline-4 also used in the Mustang GTP; during its short run, the SVO was the most expensive and the fastest Mustang available at the time. 9,844 were produced, of which 4,508 were in 1984.
