So, today I made a run to my old place of work. About 60 minutes one-way, and a route I drove for 15 years, 5 with my ex-Impreza CVT. I was filling up every 4 days. I spent most of those 5 years finding the best way to get great mileage in that Impreza. In the winter (20f) I'd get 28 mpg, in the summer (70f) I'd get 34 mpg. With today's temp (50f), I estimate I'd get 31.6 mpg.
At the end of the trip, I put almost 12 gallons into the CX-5, and calculated 28.35 mpg over the whole tank. (That's with a lot of hooning, a couple dozen 0-70ish WOT runs). The 'Average MPG' gauge in the cluster showed 28.0 mpg. The Fuel Economy panel in the touch screen showed that I got 33.3 mpg for today's trip. When the FE monitor has the same number of miles as the trip meter, they both show the same mpg, so I'm reasonably confident that I got 33 mpg actual. This is 20% 0-35 mph city, 20% 65 mph interstate, and 60% 55 mph county road stop-and-go every couple of miles to 4 miles.
As I expected, from city driving, where I clearly got better mileage than I was getting in the Imp, the CX-5 is getting fantastic mileage. (The Imp's CVT is awful on mpg when it's cold. It's got something around 7 quarts of oil in it, and it takes a long time to warm up). Both cars have Michelin X-ice 3's on them.
I get this kind of mileage by accelerating very slowly, keeping highway speeds down (I drive 65 on interstates, and 55 on county highways), and coasting to stops.
