1975 Porsche 911 Turbo

The glorious whirlwind of performance vehicles of the 1960s were quickly extinguished in the 1970s by stricter safety and emission regulations. The cravings of the performance-starved world were laid to rest when Porsche introduced their turbocharged 911. Internally dubbed the Type 930, it featured a three-liter air-cooled six-cylinder engine backed by a KKK turbocharger. With a maximum pressure of .8 Bar, or about 11.5 psi, the engine developed an impressive 260 brake horsepower at 5,500 rpm and 253 foot-pounds of torque at 4,000 rpm.

The exterior amplified its sporty persona, with muscular bodywork, flared front fenders and rear quarter-panels, and 15-inch diameter Fuchs forged aluminum road wheels, seven inches wide in front, and eight inches in the rear. The dramatic look continued to the rear, where a 'whale-tail' spoiler was added to provide additional down-force and to provide cooling to the engine compartment by way of a separate intake grille. A deep chin spoiler was added below the nose to balance the handling.

Zero-to-sixty mph was accomplished in about six seconds flat, and maximum speed approached 160 mph.

The Porsche 930 Turbo benefitted from the factory's racing program, particularly from the experience gained during the 1972 and 1973 Can-Am racing series. Its development was spurred by Group 4 homologation rules which required 400 road cars to be built. Introduced at the Paris Motor Show in 1974, production began in April of 1975 and the original 3.0-liter version would continue through 1977 with 2,819 examples built.

For 1978, Porsche enlarged the engine's bore by 2mm resulting in a total displacement of 3,299cc, and added an air-to-air intercooler which cooled the pressurized air charge, boosting output to 296 horsepower at 5,500 RPM and torque to 304 lb-ft at 4,000 RPM. Exterior modifications included a re-profiled rear 'whale tail' spoiler to accommodate the intercooler. The suspension gained new anti-roll bars, larger diameter rear torsion bars, and stiffer shock absorbers. The brakes were upgraded to help cope with the increased output of the engine.

In 1980, Porsche withdrew the 930 from the Japan and United States markets due to strict emissions regulations. They would return to those markets by the 1986 model year and given an emission-controlled engine producing 282 horsepower at 5,500 RPM and 278 lb/ft of torque at 4,000 RPM. Along with the emissions-compliant engine, Porsche introduced cabriolet and Targa variants.

For 1983, a performance option (in Europe) for the engine boosted output to 325 horsepower at 5,750 RPM and 319 lb/ft of torque at 4,000 RPM. This option was called Werksleistungssteigerung (WLS, 'Works Performance Increase') and included a remodeled front spoiler, an additional oil-cooler, and a quad-pipe exhaust system. Most examples with this add-on option received ventilation holes in the rear fenders and modified rockers.


Production of the 930 ended after the 1989 model year when its 'G-Series' platform was replaced by the 964. The 1989 models were the only 930s fitted with the Getrag G50 five-speed manual transmission.

The Type 930 did not have a direct replacement, but a turbocharged variant of the 964 did arrive several years later, in 1991, with a modified version of the same 3.3-liter flat-six engine and a five-speed transmission.
