I had to do a triple-take to make sure this wasn't a promotion for Forza or something, but yes, NASCAR has unveiled two actual real life paint jobs promoting Halo 5.
Dale Earnhardt Jr. himself will race No. 88, featuring the Master Chief car, and Jamie McMurray will drive No. 1, which sports the Spartan Locke scheme. These two characters and their rivalry provide the backdrop for the story of Halo 5.
If you want to see the cars for yourself, they'll race at the Hollywood Casino 400 at the Kansas Speedway on October 18. Make sure you bring your Gamer Fuel.
