Scott Dixon's

to claim the IndyCar championship has solidified his case as the best driver in the history of the championship.

Dixon's championship win was the fourth in his stellar career, tying him with Scotland's Dario Franchitti as holding the most IndyCar titles since the revamped series started in 1996.

After winning his debut title in 2003, Dixon also picked up championships in 2008 and 2013 to go with today's triumph, with his four successes tied with Franchitti and one ahead of Sam Hornish Jr - the trio being the only drivers to have won the championship more than once.

National Championships (1996-present)

Scott Dixon 4 (2003, 2008, 2013, 2015)
Dario Franchitti 4 (2007, 2009, 2010, 2011)
Sam Hornish, Jr. 3 (2001, 2002, 2006)

However, Dixon's dominance is the most noticeable in the overall win standings, having a massive lead at the top of the pile.

8. Ryan Hunter-Reay 14

Dixon has won 60% more than his next closest rival in the 19 years of the IndyCar competition, and rates extremely highly amongst that elite competition when judging by wins per start.

Wins per start:

1. Will Power 23 wins in 122 starts - 18.8%
2. Scott Dixon 37 wins in 215 starts - 17.2%

Including all previous iterations of the IndyCar competition, Dixon is fifth all time in wins, with his 38 total victories (Dixon won one CART title in 2001) behind only A. J. Foyt (67), Mario Andretti (52), Michael Andretti (42) and Al Unser, Sr. (39). Dixon has also stood atop the podium more than any other non-American in American Championship Car history.

Perhaps the only check not in Dixon's favour is his record in the prestigious Indianapolis 500, with his one victory in 2008 being overshadowed by Castroneves and Franchitti, who have both won three times apiece.

However, the one-off nature of that event means Dixon's four championships and huge lead in the overall win tally puts him well out in front in the race to be crowned the best driver in the history of the IndyCar competition.
