<VV> If the General says (85 mpg carburetor)

The so called waste heat comes from the basic Carnot cycle and cannot be
altered. The increase in mileage comes from more complete combustion due to
the efi and better engine design (which provides more heat) and reduced
friction and rolling resistance. The carburetor is completely out of the
picture now and as you note, no car in the world is getting 200 mpg, or as
Pogue claimed, 200 miles per pint!
