A Formula 3 racing car with a top speed of 145mph has been unveiled, which is made of vegetables and powered by chocolate.
The British-built ecoF3 racing car has a steering wheel made from carrots, a bodywork crafted from potatoes and a soya bean seat.
It uses plant oil-based lubricants to grease its moving parts and boasts a biodiesel engine capable of running on chocolate extracts and vegetable oil.
The car's bodywork was made by mixing vegetable fibres with resins and it is the first Formula 3 car built from eco-friendly materials.
But the ecoF3 is currently ineligible to compete in next season's championship because the engine's unusual fuel means it fails to meet regulations.
James Meredith, project manager of the WorldFirst team from Warwick University, in Coventry, West Mids, which designed and built the car, said the car breaks new ground.
He added: "It's been very exciting working on the project and important for our team to develop a working example of a truly green motor racing car.
"The WorldFirst project expels the myth that performance needs to be compromised when developing the sustainable motor vehicles of the future."
