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 Porsche 934 was introduced for the 1976 racing season. It was manufactured for two years, 1976 and 1977, 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 as well as the 935 were raced in the Deutsche Rennsport Meisterschaft in a distinctive orange "Jägermeister" livery.

Alan Hamilton the Australian Porsche distributor at the time owned one of these cars and competed and won the 1977 Australian Sports Car Championship and in 1980 the same car won the title with Allan Moffat behind the wheel.


The 934 has a top speed approaching 190 mph (approximately 300 km/h) and has a 0 to 60 mph (97 km/h) 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 car came in a Regular Trim, or a Racing Trim (also called Group 4 Trim). Regular Trim:

  • 1,090 kg (2,403 lb)
  • Electric windows and door trim
  • 32 gallon gas tank.[clarification needed]
  • 480 bhp (358 kW) 3 litre engine (in 1977, modifications took it to 550 bhp)

The Racing Trim was a modified Regular Trim to meet with the FIA rules, most notably it added 30 kg (66 lb) of weight, so that it complied with the minimum weight requirement of Group 4.
