Formula Overdrive

Formula Overdrive is an open-wheel racing series operating in North America. The first season was run in 2008, with Luke Warmwater winning the title. The series' sanctioning body went under after the 2008 season, leaving the series dormant until 2011, when ARLA revived the series with a nine race schedule, all on road courses. Kiriki Hetsuno won the championship.

The 2012 Formula Overdrive season is sanctioned by executives from series sponsor Hanmore, and has an even split between road courses and ovals. It is a cheaper alternative to the manufacturer-driven V8 Champ Car series, but manufacturer support for Overdrive has grown, leading to bigger purses and an increase in track attendance and TV viewership. Formula Overdrive is still seen as a feeder series to Champ Car, although Hanmore has made it known they would like to move the series closer to equal footing with Champ Car. However, Formula Overdrive has never had a stable big race before 2012, while V8 Champ Car sanctions the legendary Indianapolis 500.
