Hi I'm a fairly new member here, but I've been a lurker for a while. I started a thread over in the Fossil Fuel Free section about converting a Yugo to an EV, but I think I got a little too far into the aerodynamics there, so I'm starting this thread. Here is the other thread if you'd like to check it out (

Ok, so the big problem areas I see on a Yugo starting from the front are it's front end which slopes down toward the ground, then cuts off abruptly so that the air hits the ground, and then bounces back and forth in a turbulent manner with the underside which has no bellypan(what I imagine happens, haven't actually seen a CFD simulation or tuft testing in that area), then the back end cuts off at an awkward angle with no Kammback, the rear has no diffuser probably because it doesn't have a bellypan, and obviously the usual smooth wheel covers, rear wheel skirts, etc would be put on to reduce drag.
I downloaded a model of a Yugo in google sketchup to try and model some of these modifications. *note model of Yugo not most geometrically accurate model of any car ever*
I took some pictures of different Kammback, nose, bellypan, diffuser, etc models. I'll post these in the next posts so it's a little easier to read and digest.
