Kenseth, after leading for 163 laps, had to push hard to nose out the hard-charging Kahne, finishing just 0.15 seconds in front for his second title of the year and 26th of his Sprint Cup career.
Kenseth, in his first season driving the No. 20 Toyota for Joe Gibbs Racing, also won at Kansas in October, before it was repaved and reconfigured with new turns.
Kyle Busch and Joey Logano were involved in a crash on the 104th lap when Busch hit the outside wall. His car then took out Logano on the apron.
