The XC90 averages about 38mpg and consistently does 39mpg on long runs with lots of motorways driven at up to 80mph for long periods. Best I've managed is 44mpg with economy driving forced due to traffic conditions. Of course instant readouts or zeroing the counter before a long downhill section gives silly ridiculous figures but mine are easily achievable. Also easy to get it down to 32mpg when driven hard.Modern automatics seem to have a lot more gears (ZF box has 8) so a lot more shifty shifting so lower revs and better fuel consumption as a consequence. I believe the duck mentioned his XC90 hit the highs of 39mpg on a fairly brisk road run which is near astonishing given I drive our auto Volvo (6 speed) with half the horsepower and struggle to get above 38mpg.
I never take any notice of short journey [less than 10 mile] figures, because from a cold start the dash is always pessimistic. Nevertheless my average figure includes all journeys, however long or short.
For longer journeys I have found the dash to be about 0.5mpg optimistic when measured by pump readout and distance covered.
It is an 8 speed, but Volvo use AW transmissions as do Audi Q7 V6 diesels[and its derivatives], but in longitudinal form rather than the Volvo's transverse version [the same as many Toyota and Lexus cars that use the same box].
My Honda has a nine speed transverse ZF auto which is every bit as good, although more noisy [it groans a bit sometimes]. It doesn't do the longer trips that the Volvo does and usually not more than 100 mile round trips with no motorway. This means that, to me knowledge, it has yet to shift into 9th gear. I've been up to 70mph in it and that isn't quite fast enough to change into top.
The Honda is slightly more powerful and torquey than my Ford Ranger2.2, from a 1.6 twin turbo, and does an average of 42mpg with 50 attainable driven sensibly on longer routes. It does weigh half a ton less than either Volvo or Ranger though.
Even so the Ranger only ever manages a best of 30mpg. This is with the six speed automatic. [Averages between 18 and 22mpg on general farm work/towing] The Ford engine is notoriously thirsty by today's standards and the new 2.0 Ford with ten speed auto should achieve 35 to 38mpg with more power and performance available.
