The Environmental Protection Agency (EPA) has just released its official list of the most fuel-efficient cars sold in the U.S. during the past 26 years -- which is as far back as the EPA's database extends. Topping the chart with 49 mpg/61 mpg EPA city/highway marks and a 53 mpg combined stat is Honda's original Insight, a diminutive two-seat hybrid that first appeared in 2000 and was last sold here in 2006. Placing second in the mileage-maxer derby is the 2010 Toyota Prius, which netted 51/48/50 mpg marks while the 1986 Chevrolet Sprint ER grabbed the final podium spot with 44/53/48 mpg averages.
Rounding out the EPA's Top 10 Fuel Sippers ladder are the 1986-87 Geo Metro XFI (43/52/47 mpg), 1986-87 Honda Civic Coupe HF (42/51/46 mpg), Honda Civic Hatch VX (39/50/43 mpg), 2006-2010 Honda Civic Hybrid (40/45/42 mpg), 2010 Honda Insight (40/43/41 mpg), 2001-2003 Toyota Prius (42/41/41 mpg), 1989 Chevrolet Sprint 38/45/41 mpg) and the 1989 Suzuki Swift (38/45/41 mpg).
