The Peugeot is being designed to build up as a series of individual modules, joining together into a full representation of the car's chassis and systems. This may be a bit ambitious for a paper model, but we'll see how it goes...
This approach mimics the construction of the full-scale car; a core monocoque acts as the base to which major units are attached. All together these form an armature for the bodywork. Cooling is handled by complex pods at the sides, the drivetrain is a nearly self-contained unit attached to the back. At each corner are the brake, hub, and suspension assemblies.
If this works - in that it's buildable, and solid, and reasonably precise - I'd like to design the Eagle MKIII and Bentley this way too.
