Porsche 911 Turbo S “Leichtbau”

The terms “race car for the road” and “prototype” are overused to the point of losing their significance. In 1992 Porsche gave these words actual substance with the 911 Turbo S, a street-legal tribute to an IMSA championship-winning race car. Motorcar Journal had the rare opportunity to take the prototype from the Porsche Museum in Stuttgart on an unforgettable two-day journey through the Black Forest. 

For driving enthusiasts, the Porsche 911 is an obvious choice and since 1999 the GT3 RS is regarded as the pinnacle. For those craving comfort and everyday usability combined with even more performance, Porsche offers the Turbo S. It was not always like that though. In the 1970s the world was a vastly different place and so was the automotive industry. Porsche and BMW were pioneering the use of turbocharging in motorsport and in 1975 the first-generation 911 Turbo made its debut with the internal code 930. It served as the homologation model for the 934, a race car that entered the international Group 4 Sports Car Championship in 1976 and this 934 laid the groundwork for the even faster and more extreme 935, built for Group 5 competition.
