I just bought a new Prius to use for my work route vehicle and the Mrs is driving my F250. My 14~mpg very light city in the F250 went to 11 with her driving her short 6 mile each way commute. The Prius is returning 50-53 mpg per tank averages city and 47~ interstate at 74~mph. This way I get to keep the truck and make some money with mileage reimbursements.
