I agree with Simon: I´ve had a T-Max for nearly two years and spend most of my time commuting along the motorways with the speed (when I can) between 80 and 100 mph. The fuel consumption under these conditions is 56-58 mpg. I have never, whatever the use, managed to get the fuel consumption below 45 mpg - and that includes thrashing it under varied conditions.
There is definitely a problem with that consumption.
Has anyone yet managed to test a drive belt to destruction. I know they are due for replacement at 25,000 km - I wondered what they will go to. (out of academic interest, of course...)
