Production run of GpSpeed controllers !


This page is devoted to the Chipping Sodbury's School Rotary Racer Greenpower electric car.

This is an efficent electric racing car designed, built and raced by pupils at Chipping Sodbury School in the Greenpower schools challenge. Greenpower cars race in 1.5 hour sprint-style races on full size racing circuits and generally average a speed of around 30mph achieving equivalent MPG values of greater than 3000 MPG. The aim of Greenpower is promoting enginerring & technology as exciting careers to those aged 9-21. The concept for teams is to design, build, develop and race highly efficient "green" electric racing cars.

We had an excellent 2015 season, managing to obtain the title of "International Champions" in the International Greenpower F24 Championship at the final in Rockingham, October 2015. The 2016 season has now started and we hope that our success continues. If you ever want to see us race, follow us on social media to be notified of when we race, or contact the team (view bottom of page for details).
