Top 10 Fuel-Efficient Cars according to EPA

The EPA study of the "Top Ten EPA-rated Fuel Sippers" make it clear that new cars aren't necessarily the most fuel efficient. Although the 2010 Toyota Prius and the Honda Insight did make the list, what was more surprising was that these hybrid cars were the only autos manufactured after 2001 worthy of ranking. As it turns out, the 1986 Chevy Sprint ER and the early 90's model of the Geo Metro XFI get superior gas mileage compared to most new gasoline powered cars. These figures make it clear that advances in automobile technology do not necessarily mean greater fuel efficiency.

The most fuel efficient car on the list was the 2000 Honda Insight, which at 53 miles per gallon beats the modern Prius by 3 mpg. All vehicles tested only had 3 or 4 cylinder engines and the results only included passenger vehicles, no small trucks or vans made the cut. Since chances of finding one of those old "fuel sippers" in running condition is pretty slim, efficiency minded motorists must face the fact that any gasoline burning engine on the market today consumes more fuel than some older cars.
