Porsche 911

The Porsche 911 model series (pronounced Nine Eleven or in German: Neunelf) is a family of German two-door, high performance rear-engine sports cars, introduced in September 1964 by Porsche AG of Stuttgart, Germany, and now in its eighth generation. All 911s have a rear-mounted flat-six engine, and usually 2+2 seating, except for special 2-seater variants. Originally, 911s had air-cooled engines, and torsion bar suspension, but the 911 has been continuously enhanced, and evolved across generations. Though the 911 core concept has remained largely unchanged,^[1] water-cooled engines were introduced with the 996 series in 1998,^[2][3] and front and rear suspension have been replaced by Porsche-specific MacPherson suspension up front, and independent multi-link rear suspension.

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 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.

In a 1999 poll to determine the Car of the Century, the 911 ranked fifth^[4] — one of two in the top five that had remained continuously in production (the original Beetle remained in production until 2003).^[5] The one millionth example was manufactured in May 2017 and is in the company's permanent collection.^[6]
