Keselowski Clinches NASCAR Title for Penske, Dodge Brad Keselowski has won his first NASCAR championship. The 28-year-old Detroit native clinched the Sprint Cup title Sunday when fellow title contender Jimmie Johnson pulled out of the season finale because of a parts failure. The championship is the first for longtime NASCAR owner Roger Penske and gives outgoing car manufacturer Dodge the sweetest of parting gifts. All Keselowski had to do was stay out of trouble over the final 60 miles, which essentially turned out to be 40 victory laps around Homestead-Miami Speedway. Keselowski says over his radio, "If he's in the garage, let's race." It is Dodge's first Cup championship since Richard Petty's title in 1975. And it surely will help Penske get over a heartbreaking second-place finish in the IndyCar championship in September.
