Audi's Edoardo Mortara has kept himself firmly in the DTM championship hunt after overhauling pole-sitter Lucas Auer to win the second race at the Nurburgring.

The Team Abt Sportsline driver had only qualified sixth for the pit-stop compulsory race but his third win of the season has moved the Italian ahead of both his Audi team mate Jamie Green and Robert Wickens into second in the point's standings behind Marco Wittmann.

Neither Wickens nor Green managed to get themselves into the points while BMW's Wittmann took full advantage of his rivals' woes and produced his second podium finish of the weekend in third, further consolidating his position as the championship leader.

Wickens and Green now trail Wittmann by a clear 50-points as Team Abt's Mortara now takes the mantle as the BMW driver's chief championship rival.

Just off the podium, Team Abt Sportsline's Mattias Ekstrom fared much better during today's second race and fourth position for the Swedish veteran has just about kept him in mathematical contention of winning this season's championship.

The former double champion finished only 0.323s off the podium while his Audi stablemate Nico Muller followed Ekstrom home to complete the top five order.

Behind the lead BMW of Wittmann, Team MTEK's Bruno Spengler was the next best placed M4 in sixth position ahead of British duo Gary Paffett and Tom Blomqvist, who finished two-seconds apart in seventh and eighth.

Mercedes' Daniel Juncadella finished in ninth while Audi's Miguel Molina was the last of points paying runners in tenth position.
