The BMW M1 Procar Series made its comeback on Saturday at Hockenheim, 30 years after its last outing, when a host of former drivers took part in a race.
Ten drivers took to the track in the 500HP cars, in the first of two races that will take place this weekend as part of the support programme of the German Grand Prix.
"It was such a hoot," said three-time champion Niki Lauda. "We were allowed to drive how we wanted, we didn't have to hold back on the pace. Actually, we should have been chasing Jochen Neerpasch in the M1 Art Car, but he didn't get off to a proper start.
"And that gave me a clear run ahead. I'm going to have to seriously reconsider whether my career really is over! It was great fun," added Lauda, who took victory in the first race.
Other drivers taking part in the race included former F1 racer Christian Danner and BMW Sauber test driver Christian Klien.
"I've always wanted to race against Niki Lauda," said Klien. "It's amazing the handling these cars already had back in the 80s. Even today they feel quite advanced. And as for the sound, it's out of this world.
"You're sitting right in front of the engine, and at 10,000 revs it's awesome. You really get a sense of the car's sheer power. I can't wait for the next race."
The second show race will be held tomorrow before the start of the F1 GP.
