The event began with a prologue section to determine the eight fastest drivers from each manufacturer to proceed to the quarter-finals. Ralf Schumacher emerged fastest of the Mercedes drivers, with Mortara the best of the Audis. Susie Stoddart and Miguel Molina were eliminated, the latter crashing during his run.

Mortara came up against Mike Rockenfeller in the Audi final. Rockenfeller had defeated reigning Race of Champions champion Filipe Albuquerque in their quarter-final, before beating Oliver Jarvis in the semi. Jarvis had earlier knocked out surprise package of 2011 Martin Tomczyk.
Mortara won the Audi final by just over two seconds ahead of Rockenfeller, allowing him to proceed to the superfinal.
Mercedes finalist Spengler shaded fellow HWA driver Jamie Green in the quarters, before beating Ralf Schumacher by two seconds in the semi-final. Schumacher won against Maro Engel in their quarter-final.

Van der Zande would be unable to repeat his heroics against Spengler though, the Canadian progressing to the superfinal.
The final was made up of two five-lap races, with Spengler claiming the first in a photo finish. Mortara won the second though to give him an overall advantage of more than three tenths of a second.
