The second Future Car Challenge was on Saturday, November 5.
This year 64 vehicles both production and prototype models - completed the 60-mile route from Brighton to London, all aiming to use as little energy as possible. There were categories for fully electric, extended-range electric (cars with an electric motor supplemented by a small petrol engine that acts as a generator on longer journeys), hybrid- and hydrogen-powered vehicles, as well as vehicles with an internal combustion engine.
Each car was fitted with a data-logger to measure the amount of energy consumed over the route, with the results converted to kW-h.
The overall winner and most efficient - was former F1 designer Gordon Murray, driving his own Gordon Murray Design T.27, a prototype electric city car, with a figure of 7 kW-h.
