The 2012 Impreza, yeah. The previous versions weren't so good on gas mileage.
I mostly drive mine in the city, though it's not really
constant stop/go driving.
Let's see....per Google Maps, my daily drive is 11.5 miles one way, with 16 traffic lights and no stop signs.
There's an uninterrupted stretch of about 1 mile at 35-40mph, then later on there's 2 miles of 40-45mph.
(CVT transmission, which I rather like. Efficiency.
)
Per the trip meter, it gets 27-30mpg - it was more around 27.3 when it was cold, and was at 30-30.3 when the temperature was in the 60s and 70s a few weeks ago.
Since I got it in January, I've only really had it on the highway once though, maybe for about 7-10 miles, and it was doing around 41-42mpg there.
I might be making a trip back to my parents' place in a month or so. 350 miles, most of it on the highway.
Update: Average of the trip there and back: 36.2mpg.
