TALLADEGA, Ala. (AP) -- Kyle Busch apologized Thursday for a profanity-laced rant toward manufacturer Toyota over fuel mileage.
Busch was upset during Sunday's race at Dover because a late stop for gas cost him the victory. Joe Gibbs Racing teammate Denny Hamlin also had to stop for gas, but winner Brad Keselowski in a Dodge and Jimmie Johnson in a Chevrolet got better mileage and didn't have to stop.
Busch said in a statement Thursday his comments about Toyota and Toyota Racing Development were "misguided" and he spoke out of frustration.
Busch has suffered several engine failures this season, and missed a spot in the Chase for the Sprint Cup championship field by just three points.
