In an effort to bring even more racing action to Xbox One, Forza Motorsport 6 is adding NASCAR to its lineup of on-track offerings. With an expansion pack, the title gains 24 cars from the 2016 NASCAR season which you can now use to race on the newly added Homestead-Miami Speedway. There's also a new 10-hour NASCAR World Tour Career mode that lets you put the stock cars on the track in the different series around the globe. The game also gets new multiplayer events and improved drafting and spotting functionality to help you maneuver through the field. If you're looking to take it for a spin, the add-on is available today for $20.
