Bruno Spengler gave BMW its first DTM win for 20 years after resisting extreme race-long pressure from Gary Paffett's Mercedes at Lausitz.
A rocket start from Paffett from third on the grid brought him onto the tail of polesitter Spengler at the first corner of the race, and the pair were able to pull away from the pursuing back during the early stages.
While the gap between the two stabilized at under a second for most of the race, Schnitzer driver Spengler was able to crucially increase his advantage to around 1.5sec as both rounds of mandatory pit stops approached. This meant that despite the HWA team twice giving Paffett a quicker pit stop and the British driver producing better in and out laps than his rival, Spengler was just able to keep the lead.
Championship leader Paffett spent the last 16 laps right on his rival's trunklid; the gap never increasing beyond 0.6sec. But he was unable to mount a passing move. He lost any chance of passing Spengler when he braked slightly too late at Turn 1 on the final lap, bumping over the Ludwig curbs and dropping more than 1sec behind.
That ensured that Spengler took his 10th DTM victory and the first for BMW since Roberto Ravaglia's double win at Hockenheim in October 1992 – also in a Schnitzer-run car.
Behind them, another BMW/Mercedes battle ensued as Augusto Farfus, who had lost second place to Paffett at the start, resisted similar pressure from Jamie Green's HWA car for the second half of the race.
Green, who had started sixth, made an excellent move to deprive Edoardo Mortara's Rosberg Audi of fourth on lap nine and then ran 10 laps longer than any of the other front-runners during his first stint to move onto the tail of Farfus's RBM-run M3.
A slow final pit stop for Green, caused as the HWA mechanics struggled to fit his left-rear wheel, meant a stationary time more than 3sec longer than the Brazilian and ensured he stayed behind entering the final stint. No matter how hard he tried, he could not deny Farfus a maiden DTM podium on only his second start in the series.
Mattias Ekstrom had a steady run to fifth, the Swede finishing a second ahead of his Abt Audi teammate Timo Scheider, who had started 12th, copied Green's strategy of running a long first stint and took full advantage by exiting the pits after his final stop side by side with Ekstrom.
Champion Martin Tomczyk, who had battled with Green and Mortara for fourth during the first third of the race, took his first points finish since switching from Audi to BMW with seventh, while Mortara and his teammate Filipe Albuquerque were next up.
After starting fourth, Mike Rockenfeller dropped four places on the opening lap, let Scheider by for eighth early on and then endured a long final pit stop due to a problem with the right-rear wheel. The German had looked set to complete the points finishers in the Phoenix Audi, but fell to 13th instead.
That should have handed Robert Wickens his first DTM point, but the Canadian's Mucke Mercedes ground to a halt with a mechanical problem with four laps left. Ralf Schumacher (HWA) picked up the final point instead.
