You do learn every day, week or month new things about aerodynamics but then you can improve the already good model you have manufactured.

Here I like to thank Aerohead from that Template and ERTW for those neat simulations.

You do need to take a look of those cars aerohead mentioned and also few never ones, but you dont need to be a aerodynamic mastermind to make a car which Cd is under 0.2. Ofcourse it depends on the goals also, but then you just need to pick a vehicle that is closest to your target Cd and make few modifications to it.
vekke, you misunderstood Phil's point. there was a great deal of sarcasm in it.
He has done this and compiled the data, and was more than a little pissed that somebody would disagree out of hand with absolutely no scientific support whatsoever.
He presented the template, put it out there as one the best shapes for aero vehicles.
ERTW recently proved it out for us all.
I know I will not have as much plan taper in my design as I would like, but it will have as much taper as I can get. It only makes sense to reduce that base drag as much as possible. The aerocivic and all the other rigs, all the record setters do so.
