The Ford Mustang Mach 1 is a performance-oriented package for the Ford Mustang produced from 1968 to 1978. The Mustang Mach 1 was fitted with various performance and visual enhancements, and was only available on the SportsRoof (fastback) body style; standard equipment was a 351 ci (5.8L) Windsor V8 mated to a 3-speed manual. 1969 through 1970 Mustang Mach 1s are identifiable by the rear window louvers, named SportSlats. 40,970 were produced for 1970.
The tooling was updated in 2013, with the rear wing metal now cast onto the body and the SportSlats integrated as part of the interior due to cost-cutting issues.
