2012 Honda Civic Hybrid - 44 MPG
Honda also has a proven track record with hybrids, having been there from the start with the 1999 Insight. The Civic Hybrid is its most efficient model at the moment, beating the cheaper Insight - at least until the 2012 Insight arrives.
2012 Toyota Prius V - 42 MPG
Toyota's 7-seat Prius sneaks straight into the top 10 according to the EPA's figures, meaning larger families can finally enjoy the great gas mileage Prius drivers have enjoyed for years. 44 MPG city should make those short trips a breeze.
2012 Lexus CT 200h - 42 MPG
The Lexus CT 200h might be a Prius in fancy clothes but that still gives it Prius-like efficiency. The trade off for slightly lower figures than the regular Prius is the luxurious interior and strong Lexus image.
2011 Honda Insight - 41 MPG
The Insight made it onto our Cheap Fuel Efficiency list last month for costing only $18,200 and managing 43 MPG highway. Think of it as a cheaper Prius and you won't be too wide of the mark.
2012 Ford Fusion Hybrid/Lincoln MkZ - 39 MPG
The Fusion and MkZ just scrape into the list to add to the tally of domestic fuel-sippers. Both are much cheaper than the Chevrolet Volt and if you do a lot of longer journeys, you won't miss the Volt's all-electric range either. Ford's hybrid technology has been well proven in New York and San Francisco taxi fleets.
