Asch and Renauer will thus become the team-mates of Porsche works driver Sven Müller and Team Principal, Robert Renauer, who has also already won the drivers' title in the ADAC GT Masters.

"We are delighted to have two cars in this year's line-up," said Alfred Renauer. "It's going to be great to be back behind the wheel in the ADAC GT Masters. Sebastian Asch is a strong team-mate, with whom we can be competitive. "

Sebastian Asch is also confident: "I'm mega happy. Alfred makes a great team-mate, both as a person and as a driver. I haven't driven the new Porsche yet, but Herberth know the car inside out."

Herberth Motorsport will receive support from HB Racing with the second 911. The two outfits have been closely associated for many years now, and Alfred Renauer lined up for the Austrian team in the Super Sports Car League at the Red Bull Ring in 2018. "It has only proved possible to deploy a second vehicle thanks to HB Racing and our strong partners," added Renauer. "We have a long-standing partnership with the team and first joined forces together in the ADAC GT Masters way back in 2014. We're very pleased that the guys will be supporting us."
