Hannes Langeder from Austria managed to build his own Porsche! The car’s base frame is made from steel, but everything else is constructed from PVC pipes, duct tape and aluminium foil. With a chassis based on a bicycle frame, the Porsche weighs a mere 99.6 kilograms and can only reach maximum speeds of up to 16 km/h (if you peddle really quickly). A plus, however, is that this PVC Porsche is the quietest ‘car’ you have ever seen and that it also produces zero emissions. So this PVC Porsche is the most environmentally friendly Porsche the world has ever seen!
