Minimalist car design

I've looked further into what is actually needed to make a car - the bare minimum of parts, and I've found a few interesting things.

This is the 1937 Citroen 2CV prototype, an excellent example of intelligent, minimalist design. It has a hand start, only one light, removable seats and aluminium bodywork. The bonnet is corrugated because the designers realised that they could make the panel both stiffer and lighter by doing so. It weighs just 450kg - compare that to the Nissan Quashquai at over 2000kg. The 2CV is as simple as a car can be - everything has been designed purely with function in mind.

Here is a great video showing the virtues of the 2CV:
