BMW's Marco Wittmann has taken an utterly DTM dominant victory amid an incident packed race at the Hungaroring.

After resisting the opening corner advances from BMW team mate Timo Glock, Wittmann never looked back and strolled to a flawless five-second victory ahead of Audi's Miguel Molina who came in second.

Wittmann now leads the title chase for the first time in his DTM career by a clear 19-points ahead of Mike Rockenfeller, who endured a difficult day.

Behind the pair, the race took a much more unpredictable swing with the running for much of the afternoon split into two sub-categories as a result of differing strategies dictated by the Hankook option and standard tyre performance.

The variation in pace between the two compounds, as much as over two seconds on average, made for a welcome and surprise overtaking frenzy around the tight, twisty technical Hungaroring.

As the halfway point of the race passed Bruno Spengler was the top standard tyre runner in eleventh place, over 50 seconds down from race leader Wittmann with the entire top ten all running the option tyre.

Once Spengler made his pit stop onto the softer rubber the Canadian then began to flip the tables and eat into the advantage the front runners once had.

His magnificent comeback up to third, picking his off BMW team mates and the Audi's of Rockenfeller and Edoardo Mortara at will also paved the way for the previous standard runners to also leap up the order - a grandstand finish ensued.

Mortara, already having spent much of the race in the wars after a highly charged battle with Glock, claimed fourth.

The Audi-man and the former F1 ace exchanged paintwork a number of times during the phase where the pair battled for the final step on the rostrum.

Audi's Adrien Tambay was one of the main beneficiaries of the enthrallingly chaotic final laps to finish fifth.

The action was kicked into overdrive when Audi's Nico Muller was agonisingly spun around by the BMW of Glock at turn 1, the incident taking the pair both out of contention for points - Muller had set the fastest lap of the race during his crusade up the order from 14th.

Maxime Martin scored his DTM points in seventh as, he too, calmly negotiated his way through the pandemonium.

Antonio Felix da Costa was another to struggle late on with the standard tyre but did salvage an eighth place finish despite spending a large chunk of the race in podium contention.

The Audi's of Mattias Ekstrom and Mike Rockenfeller rounded out the points paying positions in ninth and tenth.

Rockenfeller's end to the race however wouldn't have pleased the defending champion after his team mate Tambay put manners on his elder statesman, edging him off the circuit in the process.

For Mercedes the nightmare continues after their miracle Oschersleben weekend. The Three-Pointed star yet again failed to score a single point despite Robert Wickens, their top finisher in twelfth, and Paul di Resta making substantial progress early on.

Gary Paffett couldn't even get past the second corner without incident and suffered terminal damage to his C-Coupe after being by the BMW of Joey Hand.

Hand was helpless in colliding with the Brit as Paffett's Mercedes team mate Christian Vietoris began the chain reaction by nudging the American into turn 2.
