Porsche 911

The Porsche 911 (pronounced Nine Eleven or in German: Neunelfer) is a two-door 2+2 high performance rear-engined sports car introduced in September 1964 by Porsche AG of Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged. The engines were air-cooled until the introduction of the 996 series in 1998.

The 911 has been raced extensively by private and factory teams, in a variety of classes. It is among the most successful competition cars. In the mid-1970s, the naturally aspirated 911 Carrera RSR won world championship races including Targa Florio and the 24 Hours of Daytona.

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. It was introduced for the 1976 racing season and was manufactured for two years, 1976 and 1977, with 31 in total being built. 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 911-derived 935 turbo also won the 24 Hours of Le Mans in 1979. Porsche won the World Championship for Makes in 1976, 1977, 1978, and 1979 with 911-derived models.
