Honda stopped production of the Insight a little more than one year ago. A revolutionary automobile, one of which is in comedian/auto buff Jay Leno's collection, the Insight was introduced in 1999.

It was North America's first hybrid, following the introduction of the Toyota Prius in Japan by two years.

The Insight is still around, though, and it still has a unique distinction. According to the Environmental Protection Agency (EPA), it's the most fuel-efficient automobile.

Often described as sporty but frugal, the Insight is also arguably the most unusual-looking vehicle on the road (until, of course, the Smart Car Fortwo arrives in 2008).

Despite numerous honors, the Insight never sold well — about 13,2000 during its six-plus year run. During its tenure, the Insight gained as much attention from its unique appearance as it did from its gas mileage — 60 mpg in the city, 66 mpg on the freeway.

The Insight is powered by both a 1.0-liter three cylinder combustion engine and an electric motor. Together they produce 73 horsepower with the five-speed manual transmission and 71 horsepower in the Continuously Variable Transmission. The power for the electric motor is stored in a 48-pound, 144-volt battery behind the seats.

Here are top 11 most fuel-efficient cars in North America and their city and highway mpg averages.

1. Honda Insight — 60/66 mpg
