One of Indycar's most successful drivers has described his former teammate Scott Dixon as "a chameleon" with "exceptional desire" after surpassing him for career driver's championship wins.
Dixon won his fifth IndyCar title on Monday to sit second only to American great AJ Foyt who won seven championships.
With the achievement, the 38-year-old Kiwi broke away from the four-time winners group of Dario Franchitti, Mario Andretti and Sebastien Bourdais.
Franchitti drove alongside Dixon before becoming an adviser to Chip Ganassi Racing - the team Dixon races for - and said the Kiwi's ability to adapt was phenomenal.
"He's like a chameleon. He adapts to different styles of cars and different styles of tyres," Franchitti told IndyCar.com.
"He learns from every teammate he's got. He uses every resource he can get, and he'll ask questions of them. You see the results.
"Talent only gets you so far. He's got lots of it, maybe more than I've ever raced against. That's saying a lot with some of the people I've raced against. He just keeps working at it. That desire is exceptional."
But Dixon said after yesterday's triumph it was more than just him.
"It’s all about the people, I’m the lucky one that gets to take it across the line," he said.
"I can’t thank my wife, Emma, enough, she’s been so amazing through the whole season, it’s actually the anniversary of her father’s passing today so it’s an emotional time."
