Tell me about it, am shocked myself, cause my brand new 800 returned around 18kmpl on the same highway.

I had topped up the tank on my Palio, net net I covered 500kms & the tank was exactly half full, that's 23.5 litres consumed, given the full tank capacity if 47litres.

So basically, I topped up the tank, reset the trip meter & went to Kolhapur & back covering 500kms in total using just 23.5 litres of fuel.

But like I said, there were several factors to the good mileage, no traffic at all, perfect tyre pressure, no load in the car except for me & my wife, & a steady acceleration most of the way, even though I was averagin 100kmph.

I am not claiming that the mileage given is absolutely correct, just sharing facts given the readings I got. Like many said, it could be faulty readings too.

Then unfortunately, it can differ significantly. The fuel gauge reading will not be linear, so you'll never really know how much fuel got consumed.

Dude, you are on a trip to prove someone wrong man. Accepting your opinion does not mean I am in agreement. The only way to prove this is right\wrong is to post the figures of my next trip. There is a high possibility that the fuel gauge is CORRECT, you can start accepting that just like I accepted that is could be WRONG. CHEERS !!!!

I've personally verified the FE of the 1.2 both in city and on highways traveling at various speeds. The FE has been calculated by full-tank to full-tank method (Complete top up). Various trips on different highways have resulted in the figures below.

The results are as follows:
(Highway, 5th gear, constant speed, minimal acceleration, No AC)

60 kmph -> 21 - 22 kmpl
80 kmph -> 19.5 - 20 kmpl
100 kmph -> 18 - 19 kmpl (average speed 80)
120 kmph -> 16.5 - 17.5 kmpl (average speed 90)
Reckless acceleration on all gears - 14.5 kmpl.

It is very easy to achieve these figures in a 1.2 . However, the city FE I manage in Bangalore is 12.5 kmpl

Yep, you said it dude. I agree with you, the city FE will not be anything to write home about, but at the same time if your car is well taken care of & driven sensibly then achieving 19+kmpl is not an issue. Driving fast does not necessarily mean driving rash, both the driving styles have a huge effect of FE. Most people think driving at the speeds of 100kmph is rash & consumes more fuel.

Sorry if you think so.

Anyway, I have nothing to gain by proving you wrong. I myself own a Fiat for last 2 years and I love it. But I do know that its fuel gauge is not exactly linear and that's the reason I made that comment. You may be 100% correct, but it will be better if you can check the FE over time using more reliable method (like top off-to-top off). 21 kmpl at average speed of 100kmph sounded somewhat high for me even for 1.2. (I could extract 16kmpl from 1.6).

BTW, I can not exactly recollect the source, but it said, the best efficiency is achieved at 88 kmph and as the speed increases, due to aerodynamic drag forces, the FE starts reducing and at 120 kmph, it drops by upto 30%. (I think, its too generic a statement, but I remember reading this.)

Hi! 21kmpl in 1.2 Palio sounds little audacious. However, if you got it, great. But then, right way should have been to top up the tank in stead of reading it from the fuel gauge. In such case, the figures would have been different. However, post the next highway test as well.

I never got more than 16kmpl on the highway on my Santro though!(with 50-60% a/c on)

Will do that on a longer trip considering that the tank was only half empty when I returned from Kolhapur.
