Newly crowned DTM champion Marco Wittmann admits he's at a loss to describe the emotions of winning his second title in the series after overcoming Edoardo Mortara at Hockenheim.

Fourth place during today's feature race was enough to guide the Team RMG driver to his second DTM championship since joining the series in 2013.

In doing so, the 26-year old has not only become the DTM's youngest ever double champion but also first BMW driver in history to take two titles in the championship.

While Wittmann's 2016 victory tally might not have necessarily set the world alight, the German's metronomic level of consistency has been unrivalled.

The BMW M4 driver has only recorded three-non points scoring finishes in 2016, which includes his exclusion from fourth at the Hungaroring.

"What a feeling! Being crowned DTM Champion for the second time in four years is incredible. It was a difficult season, but now the emotions are indescribable," Wittmann said.

"We fought right down to the wire and had no idea that we would finish at the top before the season started. We've done it now. Crazy.

"Massive thanks go to my team, BMW Motorsport and everyone involved."

In the end, Wittmann's eventual winning margin over Mortara was just four-points following an intriguing near-season long battle with the Audi driver.

Mortara won the final race at Hockenheim while Wittmann had to fight his way back up into fourth after dropping from second during the pit window.

Wittmann paid testament for the role in which Mortara played in this season's title battle.

"I have huge respect for Edoardo Mortara. He had a great season. In the end we did enough. Now it's time to celebrate."
