1977 Porsche 930 Turbo Coupe

The original Porsche supercar, the Type 930 Turbo arrived on the scene in 1975 and the pumped-up 911 bodywork hid a multitude of engineering changes based on the experience gained with a turbocharged version of the 911 RSR that had been campaigned in the World Sports Car Championship in 1974. Underneath the massive whale-tail lay the familiar flat-six sporting an exhaust-driven KKK turbocharger with an oil cooler, Bosch K-Jetronic fuel injection and a 6.5:1 compression ratio to give 260 bhp, making the Turbo Porsche's most powerful road car yet. With revised suspension and four-speed gearbox designed specifically for the new model (the existing five-speed from the 911 wasn't capable of handling the 406 lb/ft of torque generated by the engine), the Turbo had electrifying performance. Flared guards housed wider Fuchs alloy wheels shod with massive Pirelli P7 tyres while spoilers front and rear helped generate sufficient downforce to keep the Porsche glued to the road. As time went by, a few minor changes were made to the Turbo's specification, including 16-inch wheels in 1977. The 930 was very much Porsche's flagship, competing with supercars like the Ferrari Boxer and Lamborghini Countach on level terms, in performance if not price. Today, early 930s are becoming sought after as collectors recognise the significance of the model to the heritage of the Zuffenhausen marque.
