Environmentally friendly vehicles conjure up thoughts of a Toyota Prius hybrid or maybe a vehicle powered by hydrogen fuel cells, but a Formula 3 racing car generally wouldn’t be the first thing to come to mind. This "WorldFirst Formula 3 car" unveiled by researchers at the University of Warwick might just change that impression - and it's eco-friendliness goes way beyond the bio diesel engine that drives it. The racer is powered by chocolate, steered by carrots, has bodywork made from potatoes and can still do 125mph around corners.
