Porsche 911

The 911 is a sports car marketed by Porsche since the sixties. It is Porsche's signature model. The 911 has competed mainly in grand tourer racing, but did compete in the under two liter category of the Trans Am Series. Trans Am was limited to sedans, but the 911 qualified due to its back seat. The 911 was used in the IMSA GT Championship as well as Trans Am into the eighties. A "Carrera" version, named after the Carrera Panamericana (Spanish for "Trans-American Race"), was also available. The 911 was used in the American Le Mans Series, the successor to the IMSA GT Championship. The model continues to be used in IMSA racing in the modern WeatherTech SportsCar Championship. It was also used in the Rolex Sports Car Series before its merger with ALMS into the WeatherTech Championship. The 911 is also used in the Pirelli World Challenge, the premier series of the SCCA nowadays. The car was noted for its rear engine, which made it more competitive by placing more weight on the rear wheels. The 911 won its class in the first IMSA GT race at Virginia International Raceway, and helped Porsche win the championship. The fiftieth anniversary of the 911 was tributed at the Monterey Historics at Laguna Seca Raceway.The 911 won the under two liter class three straight years during Trans Am's golden era. Porsche would go on to dominate Category 2 in the seventies, including winning the first championship after the series changed its class names in 1976.
