Formula D

Formula DRIFT (also known as Formula D or FD) is a United States-based motorsport drifting series. Formula DRIFT was co-founded by Jim Liaw and Ryan Sage in 2003 as a sister company to Slipstream Global Marketing, the same partnership that introduced D1 Grand Prix to the United States. The new entity would solely own, operate and launch the first official drifting series in North America. Formula DRIFT is not affiliated with the FIA series of formula racing championships.

Formula DRIFT has 81 licensed drivers competing in PRO and PROSPEC (formerly PRO 2) as of October 2023. The series consists of an eight-round championship played out at race tracks across North America. Formula DRIFT is judged on line, angle, and style, rather than who finishes the course in the fastest time.
