But we shouldn't disconsider the Prius' body, in spite of the enhanced aerodynamics, is pretty much heavier than the Beetle even with the electric driveline ditched out. But well, getting a Prius body without the electric motor and batteries, fitting with either a manual transmission or a CVT, it could still have better highway mileage than a stock one. "Millerizing" its stock engine with a supercharger and retaining the idle shut-off, but without the electric motor and batteries, it could eventually also get a city mileage close to stock...
