Just a few days ago, it was clear that seven-time Nascar champion Jimmie Johnson, 46, will participate.
And now it will be all the more star-studded when Race of Champions arrives in Sweden in February.
Sebastian Vettel, who won the individual competition in the Race of Champions in London 2015, is together with the young Mick Schumacher ready for the competition.
The drivers will represent Germany.
Race of Champions, which for the first time will be run on ice and snow, will take place on February 5-6 at Pite Havsbad.
