Audi motorsport boss Dieter Gass has dismissed Timo Glock's claims that it used Nico Muller to block rivals during the Sunday DTM race at the Nurburgring.
Ex-Formula 1 star Glock strongly criticised Audi's tactics following the race, in which the BMW driver ran into the back of Muller while trying to overtake him.
Glock claimed that Audi keeps "manipulating races" by "sacrificing" some of its drivers to hold up rivals and help its leading runners.
However, Gass countered those accusations and said Glock should have just overtaken Muller.
He said: "Muller was in front, Glock crashed into him from behind on a 12-metre wide track.
"If he was so much faster than him, why not overtake?
"It wasn't Nico's mistake. It was Nico's strategy to stay out long, he drove as fast as he could.
"This is what we could see pretty clearly. Of course, he doesn't want to be overtaken.
"There's not much more to say, really. We fought hard with all cars as tyre wear was heavier than before."
Muller said he was confused about why Glock had hit him.
"I braked normally in order to make the corner," explained Muller.
"At the chicane, I closed the door to the inside, I stayed on my line and suddenly we crashed. He crashed into me.
"I don't know what happened, whether he missed his braking point, I don't know.
"I stayed on track for a long time and my tyres were going down.
"I just wanted to keep my position. It worked pretty well for two, three laps."
Call for stronger penalties
BMW motorsport boss Jens Marquardt was clear in blaming Muller for the incident.
"Timo complained about the radio that Muller braked extremely early and hard. Manoeuvres like that don't belong here," said Marquardt.
"And at the second time, they crashed. This is something for the stewards to look at, but it wasn't nice.
"Race control issued a lot of reprimands. Maybe it's time to go beyond that and issue a penalty when the stewards deem situations as being too hard.
"Some manoeuvres were not nice and that doesn't need to happen."
