BMW's Marco Wittmann travels to Budapest in the hope of repeating his previous win at the Hungaroring two-years ago to stretch his DTM championship lead ahead of Edoardo Mortara.

The Hungarian Grand Prix venue returns to the calendar once again after falling absent from the 2015 DTM schedule just a year following its initial re-inclusion to the series.

Wittmann was the last man to win around the Hungaroring in 2014 as part of the Team RMG driver's commanding championship triumph.

While the Budapest venue remains very much the same, Wittmann says the resurfaced track layout will add an extra dimension to this weekend's DTM action.

The German carries forward a healthy 33-point lead in the championship race ahead of Audi's Mortara following a highly profitable Nurburgring weekend.

"I think it is great to return to Budapest after a year away. I have fond memories of the circuit. I was very successful there in 2014, when I converted pole position into victory," said Wittmann.

"A similar result would be nice this year. However, a lot has changed out on the track since the last time we raced there. For example, there is a new surface. That will be a challenge for all the drivers."
