For what itís worth, following is the fuel mileage, and some observations, during a day-trip yesterday. It is typical if what I have observed.

Distance: 550 kms

Locale: 2 lane highways & back roads, cottage/beach roads, towns & villages. Lots of hills and valleys.

Speeds: Varied as appropriate for above. Average speed for the day was 65 km/hr (including lots of small towns & villages).
Although I did boot it past a few cars I was generally light on the go pedal (not over 120 all day)

Weather: Temperatures between 24 & 28 C all day. Had the A/C on about 30% of the time. Other times had the roof open and sometimes the windows.

Fuel Mileage: 9.1 L/100 km ( 30.0 mpg - I think that is 24.8 us)

Not bad for an 8 with automatic that gives me all the go I could ever want when I really need it. Mileage is about the same as I used to get with my 1982 528e/A.
(I am using the BMW "Long Life" 5W40 synthetic oil)

No complaints about the performance all day. I love the sport suspension on those uneven country roads - wheels stick like glue.

The intensive clean washers do a great job of removing bugs that are hitting the windshield like rain at dusk. Washers also help with the headlights but are not as effective there.

Only things I donít like are:
- comfort seats are not really that comfortable after 6-7 hours despite various setting adjustments - seem to push up on tail bone.
- Fresh air from vents is 3-5 degrees C above outside temperature due do engine heating of the intake ducts. This goes to 8-10C above in stop and go traffic. Need to turn on the A/C when it should not be necessary.
- Not enough storage room in the console and side pockets (only the front passenger has spacious pockets.)

Almost forgot - I also really like the PDC feature. I stopped in a no parking spot to let my wife out and then put it in reverse to move to a better spot. In that brief time a person walked up in the blind spot of the C pillar on my side - first indication was the PDC beeper. I immediately stopped and watched the guy walk behind my car. I think PDC should be a standard safety item on all cars.
