The Porsche 911 Turbo (930) was introduced in 1975. Porsche displayed the turbocharged model at the Paris Auto Show in October 1974, then began selling it in spring 1975.
The 930 was Porsche’s first production turbocharged 911 and initially used a 3.0-liter air-cooled flat-six with a single turbocharger. Its wide rear haunches, large “whale-tail” spoiler and boosted performance made it instantly recognizable. Porsche developed the car partly with motorsport homologation in mind, adapting turbocharging technology related to its racing programs.
A common mix-up comes from the launch timeline. The car was unveiled in 1974, but its production and market introduction date is 1975. United States exports began later, in 1976, which explains why some references associate early American 930s with that year. The first-generation 3.0-liter cars were built from 1975 to 1977; a larger 3.3-liter version followed in 1978.
