Researchers based at a university have created an environmentally-friendly race car with tyres made from potatoes and brake pads from cashew nut shells.
Eco One is the idea of WMG, a provider of innovative solutions to industry based at the University of Warwick.
The car was designed originally with a top speed of 125mph (201km/h).
It will be at the Sexy Green Car Show alongside green offerings from major names in the motor industry at the Eden Project in Cornwall from Friday.
The car also runs entirely on bio-fuels and bio-lubricants.
Project manager Ben Wood said he has tweaked the original engine and claims he can achieve up to 150mph (241km/h) given a long straight and a tailwind.
