Ex-Formula 1 driver, Lucas di Grassi, has ruled out a switch to the DTM, despite testing one of Audi’s RS 5 DTMs at the Red Bull Ring last week.

The Brazilian, who joined Audi’s sportscar squad in late 2012, joined the manufacturer’s regular DTM drivers, Mike Rockenfeller and Mattias Ekstrom, along with Formula Renault 3.5 racer, Nico Muller in an un-timed four day test in changing conditions.

Whilst di Grassi said he enjoyed his time with the 2013 RS 5 DTM, he admitted his Audi future lies in the World Endurance Championship.

“I think that there’s no other touring car category anywhere in the world that resembles an LMP sports car as much as the DTM race car does, [but] I’ve got a mid-term contract with Audi and I fully identify with the LMP program for which I’m scheduled again next year.”

In coming away from the test, the Brazilian added he learnt his driving style was similar to that of double DTM champion, Mattias Ekström.

“It was nice to see that Mattias Ekström and I basically share the same views regarding the car.

“Our driving techniques and the feedback to the engineers were very similar.

“I hope that with my combination of Formula 1 and LMP experience and my feedback I was able to assist my DTM colleagues a tiny bit.”

Audi’s DTM rivals, BMW and Mercedes, were also present at the test.
