The event's organisers have also announced an initiative to give fans the chance to be the IndyCar racers' teammates.

Thanks to the new 'ROC Factor' scheme, a driver from North America will compete alongside Canadian Hinchcliffe in the Nations Cup, while a Latin American one will be Brazilian Castroneves' teammate.

It will be the first time that both Castroneves and Hinchcliffe take part in the Race of Champions, to be held inside Marlins Park in Miami on January 21-22.

Ten drivers from North America and 10 from Latin America will be selected for a vote on social media after they have submitted the reasons why they believe they should compete in the ROC.

"ROC Factor is such an amazing opportunity," said Castroneves. "It's a bit like American Idol; one moment someone's singing in the shower and the next they're becoming a huge star! I'm really looking forward to it and can't wait for January 21/22.

"The cool thing about Race Of Champions is that every driver has a chance, no matter what they're used to racing. The variety of cars means there's something suited to everyone, regardless of whether they're from rallying, open-wheelers or NASCAR.

"So it really is all about the talent. Plus, for me, to be competing at home in Miami is always great, especially as my family and friends will be together having a good time."

Hinchcliffe added: "I'm really excited about the chance to be a part of this year's ROC. I've watched this event for years and always wanted to be a part of it, so it's a bit of an early Christmas present getting the call.

"All these incredible drivers from so many disciplines in one place, all the different cars to try, and we still have to vote for my team-mate! It's going to be a blast!"
