The subject says it all. Does anyone know which of the three pre '91 VW vans has the lowest total drag (drag coefficient and frontal area are what I'm looking for)? The Vanagons look to be very aerodynamic because they have the most serious raked windshield, but they're also a lot larger on the front.
Any ideas? I'm trying to figure out which one might be the best canidate for a high efficiency powerplant conversion.
