His father, Grahame Chilton, is a businessman who co-owned the insurance company Benfield Group[1] until 2008, when it was taken over by Aon plc for £738m.

He made one appearance in the Star Mazda Championship, at Laguna Seca – because he was a guest driver, Chilton was ineligible for points.

He drove in the 2007 1000km of Silverstone for Arena with his brother Tom, and they finished sixth overall, eight laps down on the winning Peugeot 908 HDi FAP of Nicolas Minassian and Marc Gené.

[5] This improvement in form, together with consistent points-scoring finishes throughout the season, resulted in Chilton rising to fourth place in the drivers' championship.

In November 2011 Chilton drove for the Force India team in the Young Driver test at Abu Dhabi's Yas Marina Circuit.

[6] Chilton was appointed Marussia F1's testing and reserve driver for the second half of the 2012 season, starting from the Japanese Grand Prix.

In December 2012, Nikolai Fomenko, the engineering director of Marussia F1, announced that Chilton would race for the team full-time in 2013.

He achieved his best qualifying result of 16th position at the 2013 Belgian Grand Prix in a mixed-weather session where he was one of three drivers to go out on slick tyres at the end when the track's condition was improving.

Chilton's Canadian Grand Prix retirement came when he collided with his teammate Jules Bianchi on the first lap, sending the Frenchman into the wall at Turn 4.

With no F1 seat for 2015, Chilton returned to Carlin for testing in order to assist them with their Indy Lights efforts, planning to move on to a full IndyCar Series drive in 2016.

Chilton's maiden Indy Lights pole position and race win, taking place on the same weekend as Jules Bianchi's death, was dedicated to his former Formula One teammate and karting rival.

[19] Chilton ran the 24 Hours of Le Mans for the team, retiring after 234 laps due to a suspension failure.
