The Porsche 911 (pronounced as Nine Eleven, German: Neunelfer) is a  luxury 2-door sports coupe made by Porsche AG of Stuttgart, Germany. It  has a distinctive design, rear engined and with independent rear  suspension, an evolution of the swing axle on the Porsche 356. The  engine was also air-cooled until the introduction of the Type 996 in  1998. Since its introduction in autumn 1963, it has undergone continuous  development, though the basic concept has remained little changed.
 
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. It is among the most successful competition cars ever. In  the mid 1970s, normally aspirated 911 Carrera RSRs won major world  championship sports car races such as Targa Florio, Daytona, Sebring and  Nürburgring, even against prototypes. The 911-derived 935 turbo also  won the coveted 24 Hours of Le Mans in 1979. (Wikipedia)
