For over 50 years, the number combination 911 has not only thrilled sports car fans around the world, but it also represents the successful model that embodies the heart and DNA of Porsche. This book is also about numbers and figures, listing the most important technical specifications of all seven generations of the Porsche 911. Carefully researched, Porsche specialist Stefan Schrahe traces the journey of this sports car legend over half a century with the help of an extensive collection of data. From its beginnings in 1964 with a two-liter engine and 130 horsepower in the Porsche 911 to the 3.8 liters and 400 horsepower of the latest generation of the 911 Carrera S; from the first turbo, which in 1975 catapulted the rear-engine classic into new performance realms with 260 horsepower, to the current Porsche 911 Turbo S with 560 horsepower: the evolution can be read through the technical specifications.
