Honda has finished revamping the compact Civic compact lineup with the relaunch of its two greenest models.

The refreshed 2014 Honda Civic Hybrid sedan goes on sale today with slightly higher fuel-economy ratings, while the 2014 Civic Natural Gas hits showrooms in 10 days.

Equipped with a 1.5-liter four-cylinder gasoline engine and CVT, working with a single electric motor and 20-kilowatt 0.6-kilowatt-hour lithium-ion battery pack, the 2014 Civic Hybrid is EPA-rated at 45 mpg combined (44 mpg city, 47 mpg highway).

The combined and highway figures are up slightly from last year's model, which was rated at 44 mpg in all three categories.

The 2014 Civic Hybrid starts at $25,425 (including destination). The equipment level is similar to that of the 2013 Civic Hybrid, with the notable addition of a standard Display Audio system with 7-inch touchscreen.

Option packages featuring leather seats and navigation bump the price to $26,925 and $26,625, respectively. A fully-loaded car with all available options will cost $28,125.

On February 15, the refreshed Civic Hybrid will be joined in showrooms by the 2014 Civic Natural Gas.

Featuring the same 1.8-liter four-cylinder engine and five-speed automatic transmission as last year's model, it also has an identical fuel-economy-equivalency rating of 31 mpg combined (27 mpg city, 38 mpg highway).

Pricing for the 2014 Civic Natural Gas starts at $27,430. A new upscale Civic Natural Gas Leather Navi model adds leather seats with front heating, a six-speaker audio system, and other premium features for $30,080.

As always, the Civic Natural Gas will be handicapped by a lack of public natural-gas fueling stations.

President Obama urged Congress to fund the construction of more stations in his State of the Union Address, but for now there are only about 1,000 natural-gas filling stations in the U.S., and only half of those are open to the public.

There's no shortage of gas stations though. In addition to the Hybrid and Natural Gas models, Honda also offers the efficiency-minded 2014 Civic HF, which went on sale in December 2013 and is EPA-rated at 35 mpg combined (31 mpg city, 41 mpg highway).
