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.
Introduced for the 1976 racing season, the Porsche 934 was manufactured for two years, with at least 400 being manufactured. Toine Hezemans drove this car to victory at the European GT Championship, while in the U.S., with George Follmer at the wheel, it also became the Trans-Am champion. It continued to win races throughout the late 1970s.
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 934 came in a Regular Trim, or a Racing Trim (also called Group 4 Trim). Regular Trim featured a weight of 2,403 lbs and 480 bhp 3-litre turbocharged engine, although modifications took it to 550 bhp in 1977. The Racing Trim was a modified Regular Trim to meet with the FIA rules, most notably it added 66 lbs of weight to comply with the minimum weight requirement of Group 4.
The Porsche 934 is still a potent race car at more than 30 years old, evidenced by the following video filmed during the 2009 Nurburgring Classic. Piloted by German race driver Oliver Mathai, the 934 turned a strong 9 minute, 23 second lap, including runs up to the top speed of 190 mph.
