In my h6 2.0 facelift i got the average of 6.8L/100km on motorway from multan to gujranwala...speed set on 100 on cruise control...earlier i used to drive at 130 140 and got 7 -8km/L...6.8L/100km is very very good for 2.0 isn't it??? There was a question mark in my mind when i heard that it gives 8/9km/L best but now i can enjoy this average and active the beast when ever i want...ALHAMDULILLAH one of the best choices was buying 2.0...!!!
