The engine rules are set to change for 2025 and there has been interest from Audi and Porsche to join Formula 1, according to the-race.com.

The last time Porsche was involved in Formula 1 as an engine supplier was with Footwork Arrows in 1991 delivering poor results, while Audi has never been in the category.

This week will be a meeting in Austria where is planned to talk about details of the new regulations. Audi and Porsche (represented by Markus Duesmann and Oliver Blume) will be there with Stefano Domenicali, Ross Brawn and Jean Todt, including figures from Mercedes, Ferrari, Red Bull and Renault.

Markus Duesmann is the Chairman of the Board of Management and Board of Management Member for Product Lines at Audi, he worked with Mercedes-Benz in 2005 as head of Formula 1 development. Later he joined BMW as head of Formula 1 powertrain.

Oliver Blume has been the Chairman of the Executive Board of Porsche AG since 2015.

Earlier this year a spokesperson for Porsche said:

“The VW Group is looking at whether entry into Formula 1 would be attractive for us. But no decision has been made yet.”

“Of course, Audi is always monitoring the global development of all of the racing series.”

“For this, we are also holding general talks with the FIA about the future of F1.”

“A decision about possible involvement is not pending at the moment.”

In 2020 Audi announced they will be leaving Formula E (where they won the teams championship in the 2017/18 season) at the end of the 2020/21 season so they can prepare for an LMDh programme (which includes Le Mans and Daytona) and Dakar in 2022 using an electric powertrain.

Porsche also announced they will prepare for the LMDh programme.

Oliver Blume said:

“The new LMDh category allows us to fight for overall victories with a hybrid system at the Le Mans, Daytona and Sebring.”

 “The project is extremely attractive for Porsche. Endurance racing is part of our brand’s DNA.”
