Yes, I get 26 m.p.g. (9L per 100 km.) on a clear highway run, at moderate speeds, even with large changes in elevation.

Not sure what the effect of brand new tires is on m.p.g. until they get fully "run-in",
nor whether you will get measurably better economy because of the 215 vs. 235 mm. width.

At least we know that your odometer was not affected by any significant amount with the tire downsize (circumference essentially unaltered),
so 26 m.p.g. sounds good, but you should shoot for 30 m.p.g. once the tread has worn down a bit!

If you get 26mpg on the highway, what is your around town mileage?

I averaged around 80 mph on my road trip upstate this past week and got 25 mpg, even with that stinking 10% ethanol stuff. Around 18 mpg with local traffic.

That's perfectly feasible. I can get near that range with my 2.5i (older engine, not as efficient) on highway trips.

For all its warts, the X3 is the fuel economy champ in its class.

Note that in the recent Car&Driver comparo, the overall 2nd.-placed X3 was a clear winner in:

- fuel economy
- steering feel
- handling
- fun to drive (it ran away with that one!)

Four of the most important criteria in my view.
