Scott Dixon has ended speculation about his future in the Verizon IndyCar Series by signing a multi-year contract extension with Chip Ganassi Racing, continuing his long-running relationship with the team.

Dixon, 38, currently leads the IndyCar points standings by 46 points as he bids for his fifth championship win, but was rumoured to be considering a move away from Ganassi for 2019, with McLaren understood to hold an interest in his services for its potential new team.

Dixon ended speculation that he could leave by signing a new multi-year deal with Ganassi, who he joined in 2003 and has since won all of his IndyCar titles with, as well as having raced sports cars with the team at Daytona and Le Mans.

"I have always said I have a massive amount of respect for Chip and what he’s done in this sport,” Dixon said. “This is not an easy business. His resume speaks for itself, and he’s the type of team owner any driver would want to drive for. He gives you the tools you need to go out and get the job done, with the right group of people.

“This team has been like a family to me since way back in 2002, and I’m glad I’ll be here trying to fight for more wins, championships and Indianapolis 500s for years to come.”

Ganassi added: "I think when you mention the name Scott Dixon, the numbers and the records start to speak for themselves. We have achieved a lot together, but there are no signs of him slowing down.

"He’s still the guy the championship goes through, and you know you have to beat him to get on the top step. He’s a driver that’s always thinking about the next race and how he’s going to approach it, attack it and ultimately win it.

“I’m very happy that we have the opportunity to continue this relationship and look forward to many more successful years together.”
