Im still breaking it in so the mpg is slowly creeping up , I i remember correctly the avensis was about 49mpg when i traded in.It increased about 4mpg after an ecu upgrade , which was more of a downgrade as far as I am concerned. I dont expect the 220 to get that high as an average I would hope for around 44 for my driving style. I still dont think though that its purely a gearbox problem with the acousitc noise sub 2000 revs in sixth , its noticable in all gears although much more noticable in 6th. Now dont get me wrong here , you usually have to adjust your driving and gear changes with a new car , its just something is telling me its baffle or exhaust timing related to cause this.Whom should be complaingin really , it is over the uk legal.

Hi just took posession of the 220 from new , and have read the comments about 6th gear being for over 80 mph. Previous car i had was the avensis , very similar but had 2 litre diesel and a 6 gear box. My thoery is that the 6th gear in the is220 would happily work under 80 mp at cruise , but i think its being stifled by the exhaust or perhaps engine management? What i mean is that there is an accoustic abnormality sub 2k revs which seems to be across the range of gears not unlike having a back window open slightly. Has anyone changed the stock exhaust on this model which may prove or disprove my theory or had an ecu reprogram that removed it? mpg so far after 150mile is 35.5 thanks
