At its launch in 1975, Porsche’s first attempt at a 911 Turbo, known internally as the 930, quickly established itself as a global performance benchmark, garnering a reputation as a ‘widowmaker’ even among the most seasoned of drivers. Widened bodywork with large rear deck spoiler, turbocharged aircooled flat-six power, and a manual gearbox, elevated the 911 Coupe to new heights. In the 1980s, Porsche’s nascent ‘Exclusiv Manufaktur’ program rose to accommodate customer modifications inspired by the 911 Turbo’s Type 935 racing sibling in stride with displacement raised to 3.3-litres. The result was an exclusive styling package resembling the Group 5 racer—notably with louvered steel front fenders made flush with the front hood, retractable headlamps, and vented rear quarter panels filled by wider wheels/tires.
