The top three drivers the Chase finished 1-2-3 as Johnson beat Carl Edwards and Greg Biffle. This race was well known for its spectacular finish between Jimmie Johnson and Carl Edwards, where Edwards charged into the inside of Johnson in turn 3. The turn was too wide, causing Edwards' car to not turn completely at full speed, and hit the wall, where Johnson passed him. Johnson ducked to the apron and Edwards followed, but Johnson beat him by two car lengths.
