Division 1
The Kremer dominance seemed to be continued when Ludwig clocked pole and told the reporters that he had to lift on places he went flat out - so fast was his car, stopping the clocks at 7.31,7. In the race, he dominated followed by the usual suspects Wollek, Fitz, Schurti and Stommelen, and increasing his lead each lap. Then, he met an Opel which had to be lapped - but had a fight with a classmate as well. It ended in a spin for Ludwig, and 30 seconds behind, in fifth he set off in the hunt for the lead - but he stranded at second place, with a windshield full of oil it seemed clever to accept second place. Stommelen finished third after a battle with the other two Loos cars.
Surer drove the new BMW M1 in this race, the car homologated in Group 4 with special permission; Surer won the Rennsporttrophäe with ease
An interesting experiment was a slightly overbored Capri, which was piloted by Hezemans, to see if a Capri could stand up against the Porsches, especially when it would rain. And perhaps to steal the show a little from BMW’s M1. It took a while before Hezemans got used to the Capri, but he could beat the M1 and that was what mattered.
Division 2
Heyer had a fine weekend, pole and an easy win; Winkelhock finished a strong second after he and Grohs had beaten Ertl off the line, but Ertl passed Winkelhock with such a speed that Winkelhock couldn’t believe his eyes: “Awesome!”. But when his windscreen received first water and then oil it was soon over for the white Zakspeed Capri: Ertl retired with a blown engine. Grohs was not fully used to the turbo power in his HAT BMW, and even made place for Winkelhock, but a fine third at the finish was a great result anyway.
Höttinger did not start; his works engine lost two turbos in practice, and they withdrew instead of an all-nighter for a third turbo and probably an early retirement in the race.
