The second of our five nominees for Green Car Reports' 2015 Best Car To Buy award is the new 2015 Honda Fit, the well-regarded subcompact five-door hatchback.

It's the third generation of the car sold in North America, and it's got a new powertrain, dubbed with Honda's EarthDreams label, that includes an updated 1.5-liter four-cylinder engine and a new continuously variable transmission (CVT).

We've driven the new Fit twice, and on a multi-day test over almost 400 miles, we logged a genuine 39.0 mpg using a mixture of the Normal and Eco settings.

For 2015, the CVT-equipped Fit is rated at 36 mpg combined (33 mpg city, 41 mpg highway).

It's important to note that the highest combined mileage number applies only to the base 2015 Fit LX with the CVT.

If you move up to the mid- and upper-level Fit EX models, which weighs 86 pounds more; they get a rating that's 1 mpg lower: 35 mpg combined (32 mpg city, 38 mpg highway).

You can also get a six-speed manual gearbox in the base Fit, but it will likely be a rare model--especially since its gas-mileage ratings fall to 32 mpg combined (29 mpg city, 37 mpg highway).

We've always felt the Fit was the best of the increasingly competitive subcompact segment, largely for its interior volume and the remarkably flexible interior offered by its "Magic Seat" and the many configurations it enables.

You can fold down the rear seat, you can open up the entire floor space of the car by folding it to the sides, and you can even convert the interior into a large couch by folding the front seat backs down to make a giant flat upholstered surface.

There just aren't any other cars that offer that capability among subcompacts like the Chevrolet Sonic, Ford Fiesta, Hyundai Accent, Nissan Versa, or Toyota Yaris and Prius C.

We also happen to like the cheeky styling of the new Honda Fit, which uses deep accent lines to disguise its essentially slab-sided tall-box-on-small-wheels shape.

And while the base black cloth interior isn't our favorite, the upscale interiors are quite nice and overall, the new Fit is much quieter than the last edition--although perhaps marginally less nimble in corners.
