The inaugural RAC Future Car Challenge has crowned the electric Volkswagen Golf as the judges' best overall entry.

Further awards were given to the BMW 320d EfficientDynamics diesel for the most efficient combustion engine, the electric Lotus Elise for most economical sports electric vehicle and the Mercedes B-class F-cell hydrogen car for most efficient fuel cell.

Other participating vehicles included an array of hybrid Toyotas, two electric Range Rovers, MINI, and VW's BlueMotion diesels.

The challenge, which ran from Brighton to London on Saturday, was designed to establish the vehicle that uses the least amount of energy to arrive at Pall Mall.

The 57-mile route challenged both cars and drivers in a variety of differing driving conditions, from hilly country roads to stop-start London traffic.

Having arrived in London some four hours after an 8am departure, the participating cars were lined up in a closed Regent Street for the general public to see.

The overall judges' favourite, the VW Golf blue-e-motion electric, is still in its development stages, but production is expected at the end of 2013.
