NEW YORK (CNNMoney) -- The Honda Civic Natural Gas took home Green Car Journal's 2012 Green Car of the Year award at the L.A. Auto Show on Thursday.
The Civic was lauded for being the cleanest running internal combustion vehicle as certified by the EPA and the only assembly-line produced natural gas passenger model for sale on the U.S. market.
"There is no other vehicle on American highways like the Civic Natural Gas, and this recognition has been a long time coming for Honda ()," Ron Cogan, editor and publisher of Green Car Journal, said in a statement.
"The new generation Civic Natural Gas features greater fuel efficiency, a handsome and roomier new design, and tailpipe emission levels untouched by any other internal combustion production vehicle."
The 2012 Civic Natural Gas is a fifth generation model, running on "a clean fuel that is almost exclusively domestically sourced and typically priced about 30 percent less than gasoline," the statement said. It retails for just over $26,000 and was selected from a field of five finalists that also included the Ford ( , Fortune 500) Focus Electric, the Mitsubishi i, the Toyota ( ) Prius v and the Volkswagen ( ) Passat TDI.
Only cars that were newly introduced or completely redesigned in the past year are eligible for the award. Last year's winner was the Chevrolet Volt.
The award comes a day after the proposal of new federal gas mileage rules aimed at improving fuel efficiency and reducing U.S. dependence on foreign oil. The rules aim for an average gas mileage of 54.5 miles per gallon by the 2025 model year
The new rules would add thousands of dollars to the cost of new cars within the next few years, but in the long run, regulators say, drivers will spend less on gas, outweighing the additional cost at the dealership.
