Mind you, I've spent most of my time with the Legacy cruising comfortably on the highway, and Paukert, who lives in a decidedly more urban setting, assures me that the MPGs fall fast in the city. Also, remember that the Legacy 2.5GT requires premium fuel, and I spent between $44 and $46 to fill up its 18.5-gallon fuel tank with 93 Octane that cost about $2.80/gallon.
Still, my last fill-up showed the car achieved an honest-to-goodness 27 mpg over 426 miles, which is 6 mpg better than the EPA's combined estimate and 2 mpg better than its highway estimate. And the engine appears to be gaining efficiency as we continue to break it in.
The wife and I are gearing up for a road trip with the Legacy that will add well over 2,000 miles to its odo. We'll keep track of the fuel economy we see and report back to see if Autoblog's first long-term car can keep this surprisingly good performance up.
