Aerodynamic Design of Ultra-streamlined Land Vehicles

Aerodynamic considerations are often overlooked when building a first racer, in favour of things that are easier to see and quantify. Teams will often spend much time and money on tyres, bearings and brakes and treat the shape of the bodywork as little more than aesthetics. Spoilers, wings, external cameras, etc, will be added because they "look cool" without any thought to the effect they will have on the cartie's overall drag. But physics says that aerodynamic drag is the most significant factor at speeds over about 20mph.
