Top 10 Cheapest 40 MPG Cars

4. Honda Civic Hybrid $25,150

Unlike many of the other hybrids on this list, the Honda Civic here is a mild-hybrid, which means it can’t run on electric power alone. None-the-less, the compact gets 44 mpg combined, thanks to a 1.5-liter four-cylinder engine, and a helpful electric motor. It all comes in at just over $25,150, making the Civic a pretty solid bargain when it comes to fuel savings. Check out the full specs of the 2013 Honda Civic Hybrid.
