CONCORD, N.C. -- As part of his whirlwind day in New York City this week, Jimmie Johnson joined his fellow Championship 4 drivers on "The Tonight Show Starring Jimmy Fallon."
And what better way to prepare for a championship race than to do a little extra racing -- with "Mario Kart 8," that is.
Fallon challenged Johnson and his championship competitors in an entertaining session of the game, which you can watch above.
