Dover, DE —  Jimmie Johnson once again drove a dominating NASCAR Sprint Cup race Sunday at Dover International Speedway when he took his Purolator-equipped Chevrolet Impala to victory at the AAA 400 event. It was the second race of the season-ending Chase for the Sprint Cup championship and his series-high sixth win of the '10 season on Purolator for Hendrick Motorsports. Johnson, the four-time defending Sprint Cup champion, used the win to move into the second position in Chase points after two of the final 10 events to end the season. Johnson has owned Dover the last two years, winning for the third time in four races.
