A rally designed to highlight transport technologies of the future saw more than 60 "green" vehicles attempt this weekend to cover a 60-mile distance with minimal energy consumption.
Low-emission, eco-friendly vehicles featuring in the inaugural RAC Brighton to London Future Car Challenge included electric and hybrid cars, light commercial vehicles and motorbikes.
Among the cars showcased were Toyota Auris and Prius Hybrids, electric Mini E, hydrogen-powered Honda FCX Clarity, diesel-powered VW BlueMotion Golf and Tesla electric roadster.
Rally legends Paddy Hopkirk and David Richards were pitted against each other in differently powered Minis as the vehicles were flagged off from Madeira Drive on the East Sussex city's seafront.
Formula One driver Perry McCarthy and Pink Floyd drummer Nick Mason were among other star participants.
Ahead of the rally, Professor Stephen Glaister, director of the RAC Foundation, warned that despite having the technical innovation to attempt to cut carbon emissions from cars, their development was likely to be hampered by their expense.
He said: "There is little doubt car manufacturers can overcome the technical hurdles, but what about the cost barriers?"
