The Indian pair join F1 great Michael Schumacher, Le Mans legend Tom Kristensen and WRC king Sebastien Ogier in the field for ROC 2013 to be held at Bangkok's Rajamangala Stadium on the weekend of December 14-15.
Chandhok and Karthikeyan are the only Indian drivers ever to have competed in F1 and both have extensive racing pedigrees elsewhere too.
Chandhok is a race-winner in GP2 and has since turned his hand to endurance racing with strong finishes in the last two Le Mans 24-Hour races. Karthikeyan has tasted victories from British F3 to A1GP and Superleague Formula before enjoying considerable success this year in AutoGP.
That performance has now earned Chandhok and Karthikeyan an invitation to return to the scene of their triumph in Bangkok for ROC 2013.
Chandhok said, "I'm very excited to be going back to Bangkok for the Race Of Champions. Narain and I had a great time together last year and it was fantastic to be the first ROC Asia winners. ROC is a unique event from a competitive and social perspective and it's something that every driver looks forward to.
