Also at Le Mans from 1976 – as in the World Championship for Makes – were the production cars of the “Group 5”. Straight away, the 935 based on the 911 Turbo 3.0 (dubbed internally 930) turned out to be a winner. It won its class at all starts in Le Mans – 1976 to 1981. And in 1979 it even clinched overall victory. In the later stages of development from 1977, the turbo engine developed well over 600 hp with two turbochargers instead of one. For the power transmission, Porsche put its trust in the near-standard four-speed gearbox of the 911 Turbo and a rigid rear axle. Thanks to the systematic lightweight design with doors, hoods and fenders made of GRP as well as the side and rear windows made of plexiglass, more than 70 kg of lead could be placed in the 935 in order to reach the minimum weight of 970 kilograms. With the help of this ballast, Porsche modified the weight distribution and centre of gravity. The external difference at first glance between the 935 and its street-going counterpart is its aerodynamic slant nose, the massive plastic fender flares and the distinctive double rear wing. In 1977, the aerodynamics of the 935 underwent more wind tunnel tests and was further optimised.
