2012 Future Car Challenge victor Renault Zoe

The 2013 edition of the UK's Future Car Challenge year has been cancelled. The shut down may be as much of a reflection of less-than-expected electric-vehicle interest in the UK as it is a result of a sponsor unexpectedly pulling out, according to UK's Autocar.

The annual race of alt-fuel technology vehicles, which was put on by the Royal Automobile Club (RAC) and ran from Brighton to London, was partially a victim of infighting among race organizers. Still, electric car adoption has been "far slower than expected" and may ultimately be known as an "expensive diversion," according to the publication.

Last fall's winner of the Future Car Challenge was the Renault Zoe all-electric, which won the overall title by using the least amount of energy during the 63-mile race. Other vehicles winning various categories included the Vauxhall Ampera (the sister car of the Chevrolet Volt), the Mercedes-Benz E300 Hybrid and the Jaguar XJ_e.
