Video: Dixon takes IndyCar trivia test

Just as his successor is about to be named, reigning IndyCar champion Scott Dixon took the league’s "Test Drive" trivia challenge and scored off track, too.

Defending IndyCar champion Scott Dixon is known as a smart driver, but how brainy is he when it comes to racing trivia? Fans found out as Dixon was the next person up to undergo "IndyCar Test Drive."

On Saturday – just one day before fans are about to find out whether it’ll be Simon Pagenaud or Will Power succeeding Dixon as the next league titleholder – IndyCar invited Dixon to take its trivia challenge, and the driver nicknamed “The Iceman" proved that he’s got as much of a knack for racing information as he does for actually getting behind the wheel.
