Not really any aggressive hypermiling. Fuel economy in the Prius seems to be almost the same regardless of driving style. Engine temperature and battery charge level have the largest impact on fuel economy.
This contained a 43 MPG trip into town on a cold engine, and the return trip was 54 MPG just because the engine was warmed up. Both trips were ~25 miles. |
