Honda's hydrogen fuel cell FCX Clarity will make its UK public debut at Ecovelocity and you could be one of just two members of the public to get behind the wheel of the revolutionary car.
In our competition the two winners will drive the FCX Clarity around the purpose built test track at Ecovelocity, which takes place September 8 to 11 in the grounds of Battersea Power Station. This will be the only chance that members of the public will be able to drive the car at the event.
Winners will also receive two tickets each to Ecovelocity, and we're offering three runners up a pair of tickets each to the show.
