Penske Racing and Dodge dominated Sundays STP 400 at Kansas Speedway. Kurt Busch started from the pole and led 152 of the 267 laps in the No. 22 AAA Dodge Charger, but it was Penske teammate Brad Keselowski with the right fuel strategy that propelled the No. 2 Miller Lite Dodge Charger team to victory lane. Busch finished ninth after a late stop for a splash of fuel.
For the second consecutive week, the NASCAR Sprint Cup Series race came down to fuel mileage. Unlike last week at Charlotte when Keselowski saw his chance of victory vanish when, running fourth on a restart for a green-white-checkered finish, he was caught up in a mishap. There was no mishap this time around. Keselowski took the lead on lap 259 when Busch yielded the point and headed to pit road for fuel. Keselowski coasted to a 2.8-second victory.
The final green-flag pit sequence came between laps 200 and 216. Busch made his stop for tires and fuel on lap 205. Keselowski made his top five laps later. That gave the driver of the Blue Deuce enough fuel to make it to the finish. There were 16 cars on the lead lap at the checkered flag.
While Keselowski and Busch were getting it done on the track, the pit crews were equally impressive on pit road.
