Porsche 930

Porsche began experimenting with turbocharging technology on their race cars during the late 1960s, and in 1972 began development on a turbocharged version of the 911. Porsche originally needed to produce the car in order to comply with homologation regulations and had intended on marketing it as a street legal race vehicle like the 1973 Carrera 2.7 RS. When the homologation rules changed, Porsche continued to develop the car anyway, deciding to make it a fully equipped variant of the 911 that would top the model range and give Porsche a more direct competitor to vehicles from Ferrari and Lamborghini, which were more expensive and more exclusive than the standard 911. Although Porsche no longer needed the car to meet homologation requirements, it proved a viable platform for racing vehicles, and became the basis for the 934 and 935 race cars. Ferdinand "Ferry" Porsche, who was running the company at the time, handed development of the vehicle over to Ernst Fuhrmann, who adapted the turbo-technology originally developed for the 917/30 CAN-AM car to the 3.0 litre flat-six from the Carrera RS 3.0, creating what Porsche internally dubbed as 930. Total output from the engine was 260 PS (191 kW; 256 hp), much more than the standard Carrera. In order to ensure that the platform could make the most of the higher power output, a revised suspension, larger brakes and stronger gearbox became part of the package, although some consumers were unhappy with Porsche's use of a 4-speed whilst a 5-speed manual was available in the "lesser" Carrera. A "Whale-Tail" rear spoiler was installed to help vent more air to the engine and help create more downforce at the rear of the vehicle, and wider rear wheels with upgraded tires combined with flared wheelarches were added to increase the 911's width and grip, making it more stable.

Porsche badged the vehicle simply as "Turbo" (although early U.S. units were badged as "Turbo Carrera") and debuted it at the Paris Auto Show in October 1974 before putting it on sale in the spring of 1975; export to the United States began in 1976.

The 930 proved very fast but also very demanding. The 911 was prone to oversteer because of its rear engine layout and short wheelbase; combining those traits with the power of the turbocharged motor, which exhibited significant turbo-lag, meant driving the car required more skill to drive at the edge of its (higher) level of performance. Even though the rear engine layout provided superior traction, sudden bursts of power to the rear wheels in mid-corner could break the tires loose, causing the car to literally spin out of control. This effect was amplified if an inexperienced driver would instinctively lift the throttle in reaction. The vehicle needed to be kept at high revs during spirited driving to minimise the turbo lag. Skilled drivers quickly learned how to drive the 930 properly, and with that knowledge came the ability to drive the car above and beyond the levels of most other sports cars. Nevertheless, some fatal accidents caused by drivers outside their capabilities and traffic regulations resulted in product liability law suits brought against Porsche in the US, where Ralph Nader had made his name criticizing the rear engine-rear wheel drive layout of the Chevrolet Corvair.
