After one quarter race distance, Audi Sport dominated proceedings at the Mobil 1 Twelve Hours of Sebring with Marcel Fassler leading Allan McNish aboard the Audi R18 e-tron quattros.

The pair of Audis held a two-lap advantage over the Rebellion Lola of Neel Jani which grabbed the third place spot when Lucas Luhr lost a wheel after 140 minutes.

The German had to do a slow lap to get back to the pits to replace the missing wheel.

The missing car from the LMP1 ranks was the DeltaWing which had to return to the paddock with a broken fuel injector wire after five laps. The team repaired the issue and returned to the track after a long delay but quickly retired when the engine expired in a cloud of smoke.

In P2, David Brabham took the ESM Patrón HPD into the class lead with a triple stint at the start of the race.

The battle between the two ESM machines, the pair of Level 5 Motorsports cars and the Greaves Motorsport Zytek Nissan was fierce.

Level 5’s Ryan Hunter-Reay had a scary spin while leading and the No.552 car suffered further headaches when Simon Pagenaud and ESM’s Ed Brown made contact in turn 1.

In the GT ranks BMW held the top spot after three hours despite a disappointing qualifying performance. ALMS/DTM star Joey Hand held the lead in the No.56 machine.

The Corvette of Oliver Gavin was dominant early but was delayed with a tail light issue which the team had to fix. The sister car of Antonio Garcia was given a stop +60 second penalty for contact early and later had extended visits to the paddock to fix gearbox issues.

The Risi Competizione Ferrari and the No.91 SRT Viper of Dominik Farnbacher was also remarkably fast early in the event.
