Porche 911

    The Porsche 911 is the forerunner of the current line up for Porsche. It is a two-door, high performance sports car made by Porsche AG of Stuttgart, Germany. Since its introduction in 1963, it has undergone continuous development, though the basic concept has remained little changed. The engine was air-cooled until the introduction of the Type 996 in 1998.  It has an individual design, rear-engined and with independent rear suspension, an evolution of the swing axle on the Porsche 356. Throughout its lifetime, the 911 has been modified by private teams and by the factory itself for racing, rallying and other forms of automotive competition. In the 1999 international poll for the award of Car of the Century, the 911 came fifth. It is one of the oldest sports coupe nameplates still in production, and 820,000 had been sold by the car's 50th anniversary in 2013. 911S models also gained a discreet spoiler under the front bumper to improve high-speed stability. With the cars weighing only 1050 kg (2315 lb), these are often regarded as the best classic mainstream 911s.

For racing at this time, the 911 ST was produced in limited numbers (the production run for the ST only lasted from 1970 to 1971). The cars were available with engines of either 2466 cc or 2494 cc, producing 270 PS (199 kW; 266 hp) at 8000 rpm. Weight was down to 960 kg (2166 lb). The cars had success at the Daytona 6 Hours, the Sebring 12 Hours, the 1000 km Nürburgring and the Targa Florio. The Porsche 911 GT1 is a car that was developed in 1996 for the GT1 Le Mans racing class. In order to qualify for GT racing, 25 homologation road-going models were built as a requirement. These models developed around 700 hp (522 kW; 710 PS) and did 0–60 mph in 3.3 seconds. Its top speed was 235 mph (378 km/h). Both the road and race cars carried the same twin turbocharged engine the 962 had, and the race car was a match for theMcLaren F1 GTRs during which time it raced. A re-developed version of the 911 GT1 race car was built, and this model won the 1998 24 Hours of Le Mans.
