The Porsche 934 was a racing version of the Porsche 911 Turbo, prepared to FIA Group 4 rules, similar to the Porsche 935 which was prepared to FIA Group 5 rules.
The 934 has a top speed approaching 190 mph and has a 0 to 60 mph time of 3.9 seconds. It was also one of the last designs to incorporate all the distinctive stylings of the original 911's, with only minor bodywork taken from the 911 Turbo, to include GRP (glass-reinforced plastic) wheelarch extensions, doors, engine lid and boot.
The racing variant of the road-going 930, the 934 expanded on the success of the RSR, winning the European GT Championship as well as the TransAm Championship in North America. The second 934 constructed, this car was actively campaigned through the early 1980s, culminating in a first in class at the 1982 24 Hours of Le Mans. In regards to this car, noted Porsche authority Bruce Anderson was quoted as saying “it is the most successful 934 to race in international competition.”
