FYI folks,
We just took a 3,500 mile trip in out M56 base model. North through Nevada, Idaho, Oregon, Washington and British Columbia, so you can guess at the roads. Usually about 70 mph, with perhaps 20% city/town driving. I logged the gas purchases and compared to the car mpg readout...the two were close. My observations :
1) Trip average was 26.0 mpg (not the 25.5 I thought earlier). I felt that was good.
2) The ECO setting appears to make a difference of about 2 mpg., and I only used it about half the time. So probably it could have averaged 27 mpg if I could put up with the strange throttle response on ECO more often !
3) On the highway, on ECO, you can go 500 miles before you need a gas stop...nice for long runs where we do 700 miles a day.
4) I run 35 psi in the tires, not the 33 on the car door sticker. That works well for even-across-the-tread tire wear, probably stiffens up the ride a bit, and probably helps a bit on gas. Michelins are excellent tires, but I'm biased since I worked with them for 36 years.
5) The trip started with 5,500 miles on the car, and it ended with 9,000 miles in it, so it's not quite broken in yet.
Nice car. Powerful and quiet, great stereo(premium), lots of room. Now to see how well it stands up for several years. Doug
