Dr.Michael Seal,of Western Washington University used a variation of what you speak of,with the university's Viking series of 100-mpg cars.The bellypan had a very long,upsweeping diffuser,and was designed for downforce as well as mpg.The diffuser did respect the 2-1/2 degree rule for the upswept portion.-------------------- The upper body of the cars were also very streamlined,hence the 100-mpg.
