Kiwi IndyCar champion Scott Dixon chasing racing immortality

Scott Dixon has his sights firmly set on becoming the most decorated motor racing driver in the United States.

Dixon won his fifth IndyCar championship when he finished second at the season ending event at Sonoma over the weekend.

The title means he's now trails only A.J. Foyt on the all-time winners list and the gravity of his achievement is starting to sink in.

"I'm really happy with five right now, five sounds fantastic," Dixon told Newshub.

"It's kind of funny how different it sounds to four, even though it's only one more, but it puts us into something of a rare category."

That is he is now just the second ever driver to reach five championships and first since Foyt pulled it off 51 years ago.

But has been the case throughout his illustrious career, Dixon isn't settling for second and he'll be back next year trying to move closer to Foyt's record.

"The focus right now is to enjoy this one and then once we hit the new year really try get up for that number six."

Part of the celebrations will involve the launch of his biopic The Scott Dixon Story, including its premiere in Indianapolis next week followed by a New Zealand premiere next month.

"[It's] based loosely on a full season but what goes into an IndyCar team, the family side, a lot of unprecedented backstage stuff you wouldn't get to see.

"They've done a great job of portraying the sport well and I hope a lot of people enjoy it."

While a biopic highlights just how much of a star Dixon is he always ensures his teammates, support staff and family receive due credit for his success.

"I'm just the lucky guy that gets to take it across the finish line, skull some milk or spray some champagne, but I definitely don't do it by myself."

Dixon's sprayed plenty of champagne over the course of his career, and he's still fired up to do plenty more in years to come.
