Max Chilton has made the full-time switch to IndyCar with defending drivers' champions Chip Ganassi Racing, stepping up from his rookie campaign in Indy Lights with Carlin.

The former Marussia F1 driver will jump in the #8 Chevrolet for the full 2016 campaign after splitting his time between Indy Lights and Nissan's attempted return to the FIA World Endurance Championship last year.

After the Japanese manufacturer scrapped its WEC comeback altogether late last year after struggling to master car, Chilton has opted to stay in the US on a full-time basis in IndyCar. He becomes just the fourth British driver in the past 24 years to switch to IndyCar after holding a full-time F1 drive.

"I couldn't be happier to join Chip Ganassi Racing's Verizon IndyCar Series program. This organisation is built on winning and their 11 IndyCar Championships back that up," Chilton said. "Chip is the kind of team owner that every driver dreams of working for in their career. He's accomplished so much in so many different categories over the years, and I can't wait to start driving for him."

Team owner Chip Ganassi has welcomed the British driver with open arms and is confident he's secured a potent four-car line-up for 2016 - Chiton will team-mate defending champion Scott Dixon as well as Tony Kanaan and Charlie Kimball.

"Max is a talented young driver who has driven a number of different disciplines already in a short time," Ganassi said. "He brings a good deal of experience to our IndyCar lineup and we're looking forward to him being part of our four-car team in 2016 and making a big contribution."
