AutoSpeed: lightweight, simple composite construction technique (monocoque + body)

Julian at AutoSpeed has started what looks like another really interesting series:

Building an Ultra Light-Weight Car, Part 1
An incredible way of producing your own vehicle

If you follow the green car blogs, you probably saw the University of South Australia's tandem tadpole trike EV in 2008:

Part 1 of this series shows how the students laid out that design and made its monocoque tub out of honeycomb sandwich fiberglass panels:

The beauty of this technique is the ease with which a one-off monocoque tub can be constructed. Such an approach can result in a very stiff, ultra light-weight foundation for a vehicle – all without the need for welding or metal-working!
