Porsche 911 Turbo through the decades

1974 Porsche 911 Turbo #1 chassis no. 911 560 0042. First owned by the late Louise Piëch (older sister of Ferry Porsche), the 2.7-litre 911 Turbo prototype is now on display in the Porsche Museum

Inspiration for this feature came from the post published by Porsche in December 2020. It covers the seven generations of the legendary 911 Turbo from inception in the mid-1970s right up to the current 992 model. No apology is made for using some of the text from the original feature, as this includes the unparalleled comments from rally legend, Walter Röhrl, who assisted with the development and testing of these models over the years.

The experience gained from the turbo technology used in the 917/10 and 917/30 in 1972 and 1973 in the Can-Am series in the USA, paved the way for this technology to be used in a road car application. During this time, Porsche perfected the use of turbocharging in motorsport, ironing out many of the challenges associated with this technology. In the spring of 1975, a quarter of a century after Porsche began building cars in Stuttgart-Zuffenhausen, the 911 Turbo was launched.
