Automotive X Prize: putting electric cars through their paces

The Automotive X Prize, the finals of which take place this month, aim to find a car that is both eco-friendly and fun to drive. So far, it's proving tough, New Scientist reports.

Several major motor companies now offer electric cars, including Honda, Toyota and the newly floated Silicon Valley start-up Tesla Motors, with General Motors' Chevrolet Volt joining them from next year.
