Released at the end of 1974, 11 years after the first-gen 911, the Turbo variant is almost a separate model, since the differences are flagrant. It also has its own type name, 930. Besides the turbo which boosts the flat 6 up to 260 hp, the 930 is distinguished by its flared fenders and its huge spoiler. This 3.3-litre turbo version, which delivers 300 ch, was launched in summer 1977.
