The Zimmermann-Porsche 718 Cayman S (starting number 168) was driven in the VT3 class by Wolfgang Weber, Rüdiger Schicht, Oliver Louisoder and Matthias Trinius. The Zimmermann-Porsche Cayman S (start number 132) in the V6 class was driven by Alex Fielenbach, Wolfgang Kaufmann, Joannis Smyrlis and Weber. In practice, the team focused on race preparation. The two V-cars started the 24-hour journey from positions 80 and 81 in the 122-strong starting field.
The 2021 24-hour race had to contend heavily with the weather conditions. Heavy rain set in 30 minutes after the start, causing chaotic conditions on the track. Weber in the VT3 Cayman set a high-light at this time when he drove the car into the top50. After a good two hours, conditions improved, but as darkness fell, fog moved into the Eifel region. At 9:30 p.m., race control interrupted the 24-hour race with the red flag. At this point, both Zimmermanns were in the lead in their classes.
After a good 14-hour wait, the field resumed at 11:40 on Sunday morning. In the sprint over 3.5 hours, the Mathol cars were able to maintain their position. In the end, both Zimmermann Porsches crossed the finish line as class winners.
Team boss Matthias Holle: "An optimal performance of our small team. I can't praise the drivers highly enough for their absolutely flawless job in this difficult environment. Our now perfect brake discs and pads also contributed to the success. We're proud to have got both cars to the finish and even to have taken home two class wins."
