Interesting - this is almost exactly what I get from my XFR. I am out west of the beltway so maybe I get less stop-start than you? Your highway mileage is a bit better than mine - I am around 23-24 on a rare long journey.

Just had an interesting experience......just came back from a 200 mile trip where 2/3 was flat and last 1/3 a very winding straight up stretch to 6000 feet. The average tank for going up to destination was 16 mpg. The stretch down hill was over 30 mpg but ended up for an average of 20 mpg. (I love going down hill) I believe this vehicle is performing as advertised (09 XFSC)

Yeah, I always use premium gas from either Exxon or Shell. Both cars were always properly maintained. The first XF only had 22,000 miles when the lease expired and my current XF only has 3,000 miles on it. Truth be told the engine in the first car only went on one extended road trip and the second car hasn't made it out of Dallas-Ft Worth. I have gotten the MPG up to 14.5 with the last two tanks. Perhaps I drive in more stop and go traffic than I realize.

Pretty impressive. Last weekend, we had a 160 mile round trip, mostly highway. I got 26.2 MPG driving around 72 MPH on the highway. The key to high MPG is driving very smoothly and accelerating gingerly.

BMW proved years ago that gingerly is incorrect. The best fuel efficiency is achieved by wider throttle openings to get up to the desired speed quickly and then ease back to cruise.
Smooth is important.
Basically, best fuel economy is achieved by using the brakes as little as possible. Acceleration rate does not affect fuel economy nearly as much as some people suggest.
Smooth application and release of both brakes and throttle, as well as smooth cornering with minimal tire scrubbing all reduce fuel consumption. But basically it takes x amount of fuel to increase a vehicle's speed and the rate at which you do so makes very little difference.
