June 15, 2006 The Michelin Challenge Binendum finished in Paris on the weekend, completing yet another showcase of the world’s most interesting clean technologies and energies for motorized vehicles. Each Bibendum sees a who’s who of the world’s automotive manufacturers put their latest concept vehicles on the park and this year some concept vehicles were actually rolled out for the event. One that really caught our attention was the Volvo Multi-Fuel prototype, which is optimised for running on five different fuel types; hythane (10% hydrogen and 90% methane), biomethane, natural gas, bioethanol E85 and petrol. The idea, according to Volvo, is to make use of the fuels that are produced locally. This means that less fuel needs to be transported between continents, and you can fill up the car on the fuel that is available wherever you are.
