At 24, Chilton joins Chip Ganassi Racing Teams (CGRT) after making 35 starts in Formula 1 from 2013-2014 for the Marussia Formula 1 Team. Most recently he contested the 2015 Indy Lights Championship with one win, six podium and 10 top-five finishes.
2015 saw Chilton make his 24 Hours of Le Mans debut with Nissan Motorsports in the LMP1 category, while contesting his first season in Indy Lights with Carlin Motorsport, where he won at Iowa Speedway from pole position. His 35 starts in Formula 1 from 2013-2014 included a rookie record for the most consecutive races finished (25), with 19 of them coming in his first season. Prior to Formula 1 he spent the 2010-2012 seasons in the GP2 Series scoring two wins, and contested the British Formula 3 Championship from 2007-2009 where he was a race winner. Chilton began his racing career at the age of 10 in karts.
Chilton will become the first British driver in more than a decade and just the fourth in the last 24 years (Nigel Mansell-1993, Mark Blundell-1996, Justin Wilson-2004) to have driven full-time in Formula 1 prior to joining the Verizon IndyCar Series in the same capacity.
