Joey Logano pulled away from the pack to win the FireKeepers Casino 400, becoming the 10th driver to win a NASCAR race this season.
The pole-setter moved past rookie Chase Elliott on lap 153 Sunday and stayed ahead for the 15th Sprint Cup series victory of his career in the 15th race of the year.
Elliott finished a career-best second, followed by Kyle Larson, Brad Keselowski and Kevin Harvick at Michigan International Speedway.
Dale Earnhardt Jr., who finished 39th out of 40, is the only winner from 2015 that is winless this year.
NASCAR's latest aerodynamic package made its debut, hoping to create more competitive racing. The setup included, for the first time in more than a decade, reducing the downforce to 1,500 pounds and shortening the spoiler to 2.5 inches.
