After the race resumed at lap 6 following a long safety car period, Thomas Preining and David Schumacher were battling for position when they made contact before braking for Turn 8, their cars veering into the barriers at high speed before bouncing back on track.
This created a bottleneck and led to Dennis Olsen losing control of his SSR Porsche - ostensibly due to a contact - sending him straight into the barrier on the other side of the track.
