Karun is one of the fastest drivers the Asian continent has produced and became only the second Indian to start a Formula 1 world championship grand prix when he drove for HRT in 2010.

Chandhok was the youngest ever Formula Asia champion and was a multiple national class race-winner in British F3 in 2003. He became the first man to represent India in the A1 Grand Prix series two years later before graduating to GP2, where again he notched up another first for his country by winning a race in the category.

After his most recent F1 exploits, Karun turned to LMP1 prototype racing last year and finished sixth overall with his JRM team-mates Peter Dumbreck and David Brabham in the Le Mans 24 Hours.

Outside the cockpit, Karun is an avid motorsport fan with a deep-rooted knowledge of the sport's history. Quiz him on anything to do with racing and the chances are he'll know it. So he's the perfect man to be our ambassador in 2013, to take advice on team selection and, if your brave enough, to try and beat in the Castrol EDGE Grand Prix Predictor!

Timo Glock contested 91 grands prix during in a Formula 1 career that spanned between 2004 and 2012. The German’s best results were two second places, driving for Toyota, at the Hungaroring in 2008 and Singapore in 2009.

Glock raced for Toyota for several years before the Japanese outfit withdrew from F1 in 2009. He then moved to the Virgin team (which subsequently Marussia). However, the fledgling Anglo-Russian team could not provide Glock with equipment capable of delivering regular points finishes.

Prior to the start of the 2013 season, the 30-year-old turned his back on F1 and signed for BMW. Glock now lines up in a BMW M3 in the DTM series and is hungry to return the top step of the podium, something he hasn’t been able to do since winning the GP2 series in 2007. Timo still follows F1 closely though and is looking forward to contesting the Castrol EDGE Grand Prix Predictor: “I am intrigued to see how I fare as an F1 expert, and how I do against the well-educated fans here!”

Andy Priaulx is one of the most successful touring car drivers of the last decade, having won three straight World Touring Car Championship titles between 2005 and 2007, in addition to his European crown in 2004.

An established GT racer, Priaulx won the Nurburgring 24 Hours in 2005 with BMW, with whom he has raced for the majority of his career.

He competed in the GT class of the 2011 Le Mans 24 Hours and contested select races in the LMS and ALMS in 2011 - partnering in the class-winning car in the Sebring 12-Hours.

Last year he took on the challenge of the highly competitive DTM series, again with BMW, and hopes to use what experience he gained during the season to notch up his first win in the category in 2013.
