Yeah,it's pretty whacky.GM actually released an artist's rendering of an COE 18-wheeler in the 1980s,which depicted an enormous hole between the driver's compartment and running gear below,with streamline sections supporting the upper structure.------------ As far as I know,this is as far as it' gone.No claims were made about the concept.So you and Treb are not alone.-------------------------- The twin-boom Tarf,by Taruffi(?) had driver in one boom and running gear in other,and wing-like spars connecting the two,with Cd 0.10 claimed.I think the polar-moment-of -inertia would limit a vehicle like this to the track,where it operated.----------Some solar racers have used this layout but the didn't make it into the winner's circle.------------------------ The design is a shoe-in for donut-shaped motorists.
