Main race: Alzen's last-gasp stunner

At the halfway point of a topsy-turvy event, Abt held a 5sec lead over Alzen but his Audi TT-R's tyres went off in the final stages. Alzen (AMG Mercedes) put in a sequence of flying laps to reduce the deficit, and began the final lap right on Abt's tail.

Abt ran wide with four corners to go, allowing Alzen alongside. Uwe was then on the outside for the first element of the Nissan chicane, but bullied his way across the gravel on the inside of the second element. Again, they were side by side on the following straight.

With just the right-hander of Bosuit to go, Alzen just had enough momentum to hit the front at Mitsubishi-bocht. Despite a huge punt from Abt in the middle of the corner, he held on for a famous victory, with Bernd Schneider - who started 10th on the grid - right behind both of them.

But it didn't stop there. After locking up in celebration after the finish line, Alzen's car was struck in the side by an apparently furious Abt, sending Uwe into a spin. As the cars reached Parc Ferme, Abt ran over to Alzen's car and appeared to remonstrate with the still helmeted driver.

Afterwards, however, Abt claimed that the collision was unintentional: "It was a bit confusing. I thought there was one more lap to go but he completely locked up in front of me. My car got into a slide and I ran into him."

Alzen, meanwhile, merely smirked as Abt related his side of the story with an increasingly red face...

"It was a hard race and there was a bit of contact, but it was all fair," said Alzen nonetheless. "That was one of the best races I have ever driven."

More Mercedes vs Audi contact occurred in the pits, when Peter Dumbreck pulled out of his pit bay and collided with Laurent Aiello. The Frenchman got ahead a few corners later, only to spear off at the ultra-fast Rob Slotemaker-bocht, his car almost rolling as it clattered into the banked gravel trap. Dumbreck was given a stop/go penalty for the incident and finished seventh.

Local hero Patrick Huisman was a popular fifth, ahead of Marcel Fassler and the top Opel of Timo Scheider.
