The new 2015 Subaru Legacy is a stealth car: Other drivers may not pay it much attention, but it's sneaking up on the high-volume vehicles in the ultra-competitive mid-size sedan segment.

The latest Legacy, redesigned and re-equipped for 2015, is the most competitive Subaru sedan yet--and it also delivers the highest fuel-economy rating of any mid-size sedan with all-wheel drive.

That's a smallish universe: The others are the 2015 Chrysler 200 and Ford Fusion.

You can't get all-wheel drive on the Chevrolet Malibu, Honda Accord, Hyundai Sonata, Kia Optima, Mazda 6, Nissan Altima, Toyota Camry, or Volkswagen Passat for any price.

But the four-cylinder version of the 2015 Legacy is still rated at 30 mpg combined (26 mpg city, 36 mpg highway), far better than the all-wheel-drive Chrysler's 22 mpg combined or the Fusion's 25 mpg.

Now we've driven both the four-cylinder and six-cylinder versions of the new 2015 Subaru Legacy--and High Gear media editor Marty Padgett delivers our conclusions on the video above.

As the review says, "The 2015 Subaru Legacy is no niche vehicle. You may not have put it in the same thought bubble as the Nissan Altima, Honda Accord, or Ford Fusion--but now, you should."
