"We got the best out of it and we were as strong as we could be," he noted. "We had a good car and I am quite happy with my speed. Now, we are looking ahead, because at the end of the year is when it matters."
Fellow Brit Gary Paffett, who was only 12th in qualifying, trailed him home in fifth after an impressive recovery drive, while Bruno Spengler and Maro Engel were sixth and seventh respectively.
Tom Kristensen took the final point, bumping Norisring winner, Jamie Green down to ninth on the last lap. P8 was some consolation for Kristensen who squandered his pole by picking up a drive-through for not lining up correctly in his box on the starting grid.
Mike Rockenfeller initially completed the top ten, however a collision with Alex Premat near the end landed him with a 30 second penalty post-race and he dropped to 13th. That moved Susie Stoddart up to P10, with Ralf Schumacher eleventh and Mattias Lauda twelfth.
Of the rest Tomas Kosta was 14th followed by Oliver Jarvis, Premat and Katherine Legge, who was classified in 17th.
Two runners were not classified - namely Markus Winkelhock and Johannes Seidlitz, the former went out on lap 24 after picking up a right rear puncture, while the latter stopped on lap 5.
The DTM now heads to the Nurburgring in two weeks time for the sixth round in this year's championship.
