I havent got a figure of 17 kmpl yet as I havent exclusively driven on highways. For city driving 17 is almost impossible, even 15 is also hard to attain. But still smooth driving definitely improves FE.
You posted a pic showing 17.6 kmpl few days back- what were the % of highway and city if you remember.
..
@Rightnow : that was just for the sake of attaining the numbers. i did a tank full and then reset the tripmeter.
Drove at a speed of 50 in 5 gear for 15 kms without AC(some stops ) , i saw the numbers increasing and increasing
I think 12-13 is a good city mileage with AC and only way polo is able to achieve is due to the 3 cylinder engine
my i10 used to give not more than 11
@Toughguy : even i have heard some ppl claiming more than ARAI but only heard for diesel engines even i heard the same for swift and nissan micra 26 kmpl can you believe ,, diesel engines getting more and more advanced and refined
