Audi's Edoardo Mortara holds the belief that he can overhaul a 14-point deficit to snatch the DTM title away from BMW's Marco Wittmann at the Hockenheimring.

The race for the 2016 DTM title will reach its crescendo at this weekend's Hockenheim double-header finale with 39-points covering the top-three drivers.

Despite scoring nil-points during a dramatic second Budapest race, Mortara's title hopes has been boosted by Wittmann's exclusion from the race two result.

The top-three championship runners - Wittmann, Mortara and Jamie Green - sensationally clashed at the Hungaroring but the BMW driver recovered and went onto finish in fourth.

However, Wittmann was excluded from the result after the underfloor of his BMW M4 was found to have fallen below the sufficient thickness, thus bringing Mortara and Green back into the championship frame.

"I look forward to the grand finale and am traveling to Hockenheim with optimism and full of self-confidence," said Mortara.

"We won the first race of the year there in May and should have a chance for victory in the finale as well. My Audi RS 5 DTM felt really good most recently at the N?rburgring and at Budapest.

"The team's working superbly, plus the engineers and the mechanics are doing a great job. That's how we managed to clearly reduce the gap to Marco (Wittmann) on the past two race weekends.

"There are only 14 points separating us. Now, we're hoping to overtake him in the final sprint. We're not going to give up and battle up until the end."

Due to Mattias Ekstrom's World Rallycross commitments, Audi has shuffled its line up slightly as Mike Rockenfeller joins the Abt Sportsline squad alongside Mortara, while Rene Rast fills the gap at Team Phoenix.

Mortara was victorious in the season opener at the very same Hockenheim venue back in May as Audi won both races at the German Grand Prix venue.

"Obviously, we're going to leave no stone unturned to deliver an equally strong performance as in the past two years," said Audi's DTM boss Dieter Gass.

"We know that our RS 5 DTM is very fast at the Hockenheimring. That makes us optimistic. Naturally, we're also aware of all the things that can happen in a DTM finale.

"That we're actually still in contention for all three titles proves that we're looking back on a very good season. But we haven't reached our goal yet. Everyone involved in this effort has to do a zero-defects job."
