NASCAR Heat 2

This is one of the most time-consuming achievements in the game. You need to complete ten full seasons in the Career Mode across all three series. You begin Career Mode in the Truck series, slowly moving up to Xfinity and Cup. It is a great idea to lower your race length to 4% and set the AI difficulty to easy so you can rack in a lot of wins. While working on the ten seasons, make sure to win the championship at each level (Truck, Xfinity, Cup). After that, you can chose to race in whichever series you like. The Truck series has the shortest races, but also force you to race in Xfinity fill-in races. The Cup series has the longest races, but no fill-ins races. Work on your 200 wins and 500,000 speed points at the same time to reduce grinding later on. As noted in the Roadmap, only sign to one series at a time, or you will be doing a ton of unnecessary races. Once you complete your 10th full season in Career Mode, this achievement will unlock.
