That would work if most cars weren't so overpowered compared to trucks, but as it is, the vast majority of cars don't have gearing sufficient to insure the engine is always at a relatively high load and in a favorable portion of the BSFC map, which is why P&G works. A properly geared/sized engine won't need P&G to maximize efficiency, it's already there.
