Total power output from the engine was 260 PS (191 kW; 256 hp) at 5,500 rpm and 329 N⋅m (243 lb⋅ft) of torque at 4,000 rpm, much more than the standard Carrera it was based on. The engine has a compression ratio of 6.5:1. In order to ensure that the platform could make the most of the higher power output, a revised suspension, larger brakes and a stronger gearbox became part of the package, although some consumers were unhappy with Porsche's use of a four-speed transmission whilst a five-speed manual transmission was available in the "lower trim" Carrera.
Porsche badged the vehicle simply as "Turbo" (although early U.S. units were badged as "Turbo Carrera") and introduced the vehicle at the Paris Auto Show in October 1974 before putting it on sale in the spring of 1975; export to the United States began in 1976.
