Bruno Spengler took his first DTM victory of the season at Spielberg on Sunday to move into the championship lead.
The Canadian controlled the race from pole position, only losing the lead briefly during the pit stop cycles and heading a clean sweep of the podium for BMW.
By the midway point of the race, it looked like ex-Formula 1 racer Timo Glock was on course for a sensational victory on only his third DTM start. The MTEK BMW driver took option tires as the pit window opened on lap four and completed a 29-lap stint on the softer rubber to haul himself up from 11th place to second -- and only one second behind Spengler -- with the first round of stops done.
But a delay fitting his left-front wheel at his second stop not only lost him more than a second to Schnitzer driver Spengler, but also dropped him behind his MTEK teammate Marco Wittmann, who had run inside the top three for most of the race. Wittmann finished just 1.5sec behind Spengler after a sensational drive for the series rookie, with Glock behind.
Mike Rockenfeller and Mattias Ekstrom proved the pace of the Audi on standard rubber as both ran long final stints to gain track position and finish fourth and fifth.
Rockenfeller, who lost the championship lead to Spengler, spent a large part of the race battling with the Canadian's team-mate Dirk Werner, but showed stronger pace following the final stops.
Ekstrom, meanwhile, grabbed fifth with two laps to go after snagging the rear of Augusto Farfus's RBM BMW at Turn 5 and sending the Brazilian off-line. Farfus was followed home by Christian Vietoris, who was the best of the Mercedes drivers in seventh for HWA, Werner and Gary Paffett.
Like Spengler, Mercedes drivers Paffett and Pascal Wehrlein ran long first stints on option rubber, but could not match the pace of the BMWs.
HWA driver Paffett was given a two-second pit stop penalty for elbowing Martin Tomczyk off the circuit while overtaking him at Turn 3 early on, while shortly afterward his teammate Roberto Merhi spun the RMG BMW around exiting Turn 2 and was given a 10sec stop-and-go penalty for his troubles.
Edoardo Mortara grabbed second at the start, and despite losing out to Wittmann early on, still looked set for a podium until he and the German banged wheels shortly after the latter's final stop, damaging the Rosberg Audi and leaving Mortara unable to do better than 15th.
Daniel Juncadella and Jamie Green came together on the second lap, the Mercedes driver spinning as a result, while Joey Hand's race ended when a front wheel fell off his RBM BMW shortly after his first stop.
