No matter what they say about cars, they are no really eco friendly because of how they are made and all of the metals, plastics and other materials used. But this guy from the Ukraine certainly has the right idea.
The car is made from wood, which makes it pretty strong, but you would think heavy, but it uses an old 1981 Opel engine to power it along but I doubt if has a serious acceleration and top speed. However as an exercise on what can be done it’s a good idea, although it’s not likely to be taken up by the major car makers, yet!
