I tried to figure out how to make a real small drag into a 4 seater car, thus going 55 mph at 0,5 gallons / 100 km ( MPH 124 ).
I had roughly drag coefficient 0.17 here. This mean very low and clean body...not very practical for inner city driving.
Dimples would certainly lower the drag.
My 2001 Audi A2 1.2 TDI 3L transports four persons quite comfortably at an average fuel consumption of 78 mpg. When on the highway the consumption drops to 87 mpg.
