Formula One champion Michael Schumacher will compete against world rally championship leader Sebastien Loeb in December's Race of Champions.
Schumacher has a chance to claim another title
The rally-based event will take place at the Stade de France in Paris on a one kilometre, figure-of-eight track.
"I'm really looking forward to it, it looks a lot of fun," said Schumacher.
Promoter Michele Mouton said: "We're thrilled he accepted our invitation. Rally drivers will not want to lose to a circuit driver."
Schumacher is not the first driver from outside the world of rallying to take part in the event; F1 star Fernando Alonso and Nascar legend Jeff Gordon have both previously been competitors.
But if Schumacher goes on to win a seventh world title this year, as seems certain, he will be the first reigning F1 world champion to take part.
