"I’m delighted to be coming back to the Race Of Champions once again. It is always a great event with a special atmosphere. You get to race against the best drivers from all over the world and we enjoy our time both on and off the track as we meet old friends from all the different motor sport series," said 2009 Formula One world champion Button.
"The main thing is that everyone wants to put on a good show for the fans – and we only pretend to play it cool before giving it everything when we’re revving up the cars on the line. I urge race fans to get themselves to Miami in January to enjoy the action up close and personal and to give us a cheer."
Coulthard, who won the 2014 Race of Champions in Barbados added:
"I’m delighted to be coming back to the Race Of Champions. I was proud to win it a couple of years ago, beating off drivers who I’ll admit are younger and more talented than me! But that’s the nature of the knockout system. You also get a chance to compare your driving with a wide range of different drivers from all over the world in a lot of different vehicles, while having fun out of the car."
"The Race Of Champions is even better for race fans. The stadium environment is what makes it special: you look down on the cars from the grandstands so it gives you a view you wouldn’t get in many venues," he continued. "If anyone wants to remember why they enjoy motor sport, they should come along. Look forward to seeing you in Miami."
Petter Solberg, Tom Kristensen, Kurt Busch, Travis Pastrana, Tony Kanaan, and Ryan Hunter-Reay will all take part in the event which will take place in the United States for the first time on January 21-22, with more drivers set to be confirmed in the coming weeks.
