Top 10 Most Fuel Efficient Used Cars

1. 2006 Honda Insight (manual) – 52 MPG Combined

Has a more jelly-bean shaped car ever been built? The 2006 Honda Insight may be shaped like a partially eroded bolus but it beats all comers in this AutoGuide fuel-economy shootout at the P.U. Corral.

This tiny hybrid is powered by a minuscule 1.0-liter, three-cylinder gasoline engine that puts out just 73 horsepower. Most lawnmowers have more muscle. Torque is equally slight at just 79 lb-ft.

In its most efficient trim the Insight is equipped with a five-speed manual transmission, a combination that nets 48 miles per gallon in city driving and up to 58 on the freeway! Its combined score is a whopping 52 MPG. Pedal-powered tuck-tucks use more fuel than that!

With such impressive mileage this little Honda is a car of the future, and surprisingly is actually about seven years old. How insightful!
