Porsche 934

The Porsche 934, also called the 911 Turbo RSR (934), is a racing version of the 911 Turbo prepared to the FIA Group 4 rules, in the same way that the 935 was prepared to the Group 5 rules. It was introduced for the 1976 racing season and built for two years, 1976 and 1977, with 31 made in total. Toine Hezemans drove one to victory in the European GT Championship, George Follmer won the Trans-Am title in one in the United States, and it carried on winning races through the late 1970s. In regular trim the 3 litre flat-six made 480 bhp and the car weighed 1,090 kg, with a top speed approaching 190 mph, and the racing trim added 30 kg to meet the Group 4 minimum weight. It was one of the last designs to keep all the distinctive styling of the original 911.
