- 10 inch wheels - affects packaging for WHUBs, suspension, and frame primarily
- Narrower track (~46", front and rear)
- Smaller wheelbase (60")
- Complete frame redesign - no rear box
- Lower occupant positioning - CG focused
- Lots of downforce
Once again, the focus will be on mass, aero, and mechanical grip. All of these need to be understood on at least a high level to design an architecture, as many of these enablers and decisions will drive packaging. For example, originally I started with a rear box because I thought diffuser design would dictat my suspension points, but with CFD I've found that I can actually get better downforce with a shorter diffuser (more on why that is in another post).
So let's take a walk through how to set up an architecture:
