Weak Signal's description 
The WorldFirst Formula 3 racing car drives down the straight of a test track at Bruntingthorpe near Lutterworth, in Leicestershire. The steering wheel is made from a polymer derived from carrots and other root vegetables while the seat is flax fibre shell, soy bean oil foam and recycled polyester fabric. Cars powered by chocolate, steered by carrots with drivers sitting on soybean oil foam seats - it's motor racing's cheap, cheerful and environmentally-friendly series of the future. The biodiesel WorldFirst F3 car, designed as a riposte to Formula One's "carbon excesses," is the brainchild of researchers at the Warwick Innovative Manufacturing Research Centre, who developed the prototype for just 220,000 dollars. The WorldFirst team insist there there is no need to compromise on performance while at the same time "effectively managing the planet's resources."
