Dale Earnhardt Junior’s victory in last weekend’s Quicken Loans Race for Heroes 500 at Phoenix International Raceway clinched the 2015 Sprint Cup Series manufacturers’ title for Chevrolet – its thirteenth straight and thirty-ninth overall. Chevy drivers have rolled up fifteen wins this season – including three by Earnhardt – and built an insurmountable sixty-nine-point lead entering the season finale at Homestead-Miami Speedway.
Toyota has also clinched the manufacturers’ title in the Camping World Truck Series. It’s a tight race in the X-FINITY Series with just five points separating first-place Ford from second-place Chevrolet. Toyota is third, twenty points off the pace heading into Saturday’s season-ending Ford EcoBoost 300 at Homestead-Miami Speedway.
