Porsche's legendary 917 was no longer eligible to compete in World Sports Car Championship racing after the 1972 racing season, and instead of creating an all new car from scratch, the Zuffenhausen automaker decided to tackle the new European GT Championship instead.

The basic 911 was eligible for the FIA's Group 4 GT class, but Porsche knew that it needed to cut weight and increase output. The basic 2.4-liter air cooled flat six was bored out from 84 to 90 mm to become a 210 horsepower 2.7-liter, and wider rear wheels were fitted to deliver power to the pavement. Interestingly, Porsche chose to keep the 70.4 mm stroke. Fiberglass and ultra thin gauge steel dropped weight substantially.

To comply with homologation rules, Porsche had to offer 500 race-specification Carrera units to the public. Demand from customers far exceeded the homologation requirement; ultimately, 1,580 were built between 1973 and into 1974.

Extensive wind tunnel testing helped Porsche create aerodynamic body modifications that included the distinctive “duck tail” rear spoiler designed to improve upon the 911's often tricky high speed cornering characteristics.

This car was auctioned off by RM Auctions in August of 2010 at the Portola Hotel & Spa and Monterey Conference Center, Monterey, California and in May of 2012 at the Grimaldi Forum, Monaco.

210 hp 2.7-liter air-cooled, horizontally opposed, rear-mounted six-cylinder engine with fuel injection, five-speed Type 915/08 manual gearbox in rear transaxle, fully adjustable four-wheel independent suspension with coil-over shock absorbers and adjustable anti-sway bars, and four-wheel hydraulic disc brakes. Wheelbase: 89.3".
