Mercedes' Maro Engel has claimed his first ever DTM victory after resisting a final-lap charge from Mattias Ekstrom at the Moscow Raceway.

The 31-year old sealed his maiden win in the series on the 52nd time of asking after an early safety car period altered the paradigm of the race.

Engel was one of four drivers' to pit at the end of the opening lap, four laps before Maxime Martin's retirement from the race called the safety car into play on lap five.

That subsequently turned Engel's early tyre change into a free pit-stop, which ultimately gave the German the strategic high ground for the remainder of the race.

Audi's Ekstrom almost spoiled Engel's party right at the end of the race, but the Swedish veteran ran out of laps after making a late charge to second.

Pole-sitter Bruno Spengler completed the podium order for BMW in third while Rene Rast falls behind Ekstrom at the championship summit by a single point after finishing fourth.

Team Rosberg's Jamie Green completed the top-five order for Audi. The Brit almost pulled an audacious lunge, which would have propelled him ahead of Spengler and Marco Wittmann and onto the podium.

However, Green couldn't quite get the exit he needed from the final corner, which allowed Spengler to reclaim third while Rast also punished the Brit to take fourth.

Reigning champion Wittmann eventually settled for sixth, ahead of Mike Rockenfeller, Tom Blomqvist, Lucas Auer and Robert Wickens - all completing the remainder of the points paying positions.
