10l/100km is pretty good for that size engine i think, the euro claims 9.1 (2.4l), currently im on 8.4-8.6 with 1/2 city/hwy driving, my bro has the new kluger with he aurion engine in it it has been doing 16-17l/100k, yes its 4wd and should be heavier, but thats a massive difference when they claim 11l/100km kluger, so maybe the 10 for the aurion is ambitious as well
