NASCAR NATIONWIDE

Food City 250

Site: Bristol, Tenn.

Schedule: Friday, qualifying (Speed Channel, 5 p.m.), race (ESPN, 7:30 p.m.).

Track: Bristol Motor Speedway (oval, .533 miles, 36 degrees banking in turns).

Race distance: 133.25 miles, 250 laps.

Last race: Carl Edwards took the lead in the pits, then drove away for his first NASCAR Nationwide victory at Michigan International Speedway and 16th overall series win. The reigning series champion was trailing Tony Stewart when the leaders drove onto pit road under a caution flag on lap 93. Edwards came out in front and easily led to the end of the 125-lap race on the 2-mile oval.

Last year: Kasey Kahne passed Ryan Newman with eight laps to go and then held off several charges from Jason Leffler to win at Bristol Motor Speedway. The race was marred by a NASCAR scoring error against Kyle Busch that cost him a chance to run for the win. Busch was penalized with 77 laps to go and had to forfeit his second-place position, a penalty NASCAR later said was incorrect.

Fast facts: NASCAR discovered the teams of Joe Gibbs Racing’s No. 18 and No. 20 Toyotas deliberately attempted to mask the true horsepower in their engines after last week’s race at Michigan. Inspectors found magnets under the gas pedals of both cars when they were sent to the chassis dyno for examination. Tony Stewart finished third in the No. 20 in his final Nationwide race for JGR. … Points leader Clint Bowyer won the rain-shortened event at Bristol on March 15 and has two top-five finishes and another top-10 showing in his last three starts there. … The top three drivers in the standings are separated by only 132 points, the closest margin with 10 races remaining since four were within 135 points of the leader in 2003. … Four-time Bristol winner Kevin Harvick will not compete at the track for the first time in his Nationwide career, ending a string of 16 straight starts that dated to the spring race in 2000. Cale Gale will drive the No. 33 Chevrolet instead.
