Japan is known for both its engineering ingenuity and quirky weirdness and the following concept cars illustrate this dual principle perfectly. Among our favourites is the Eliica (ELectric LIthium-Ion CAr) that not only boasts 8 wheels but an electric motor in each.
Other concepts have more serious backers even, such as the early ideas of Toyota and Mazda. In 1974, Toyota unveiled the RV-2 concept. The rear opened partially and created a space across which you could span a tent.
We also like the Bambgoo. Developed by Kyoto University, the Bambgoo was a small electric car made from nothing than bamboo and also capable of running 31 miles on a single charge.
