Our current ride is a Vento 1.6 TDI. Prior to that we had a 2009 diesel i20 5 speed.
Case 1: i20
ARAI figure: 21.xx
City: 12
Highway: 16(Normal driving)
15( on driving fast)
17( the best)
Case 2: Vento
ARAI figure: 20.xx
City: 13-14(regularly)
Highway: 19( normal driving)
17-18( on driving fast).
20( best yet)
The only reason I can attribute this difference is: 1.Torque delivery at lower rpms( 1500 rpm for vento vs 2000rpm for i20)
2. Better gear ratios in the vento ( tall gear ratios in the i20)
3. Better drivability due to the above reasons
Conclusion: Never ever consider those figures. Car makers can literally tune their cars to 'top' an 'exam'.
Note: I don't know what will happen after I receive the ECU updates for the vento. Won't mind as long as the figures are higher than the i20
I think another factor is power to weight ratio. If it is optimum then fuel efficiency shall be better. Thats why it may be better in vento than i20.

ARAI figures are at a constant speed often 70kph for diesel, and 50 kph for petrol.
I have a Polo as my daily ride, ARAI figures for Polo are 23km/lit.
I often get the stated figures if I stick to speeds below 100. On a recent trip to Konkan region from Pune, sticking to 100 upto Satara, a burst upto130-140 for next 40 km before 4 laning ended, and 80 on the two lane highways returned 21 inspite of all the ghats, mini ghats there.

City with B2B traffic: 12 KMPL
Highways - 120 kmph @ 6th gear: 17 KMPL / 100 kmph @ 6th gear: 18.5 KMPL

The data is usually with 3-4 people on board and not much luggage.

Vehicle: Tata Zest XMS QJT
On Highways : 21.5 kmpl with AC on for 50% of times.
City: 17 - 19kmpl depending on traffic situations.

I have seen that use of AC does not reduce the fuel efficiency significantly.

50% of this tankful was not driven by me. I guess the car gave around 18.5 kpl highway mileage when I drove it at 90-110 kmph with AC. That's a completely acceptable figure for me!

Conclusion: Never ever consider those figures. Car makers can literally tune their cars to 'top' an 'exam'.
I had the same impressions about the manufacturers posted ARAI figures.
Honda City Diesel:
ARAI figure: 26 KMPL

All of the below are actuall efficiency observations are driving 20K + KM over the last year.


The vehicle easily returns 26 KMPL or even more average on the highway provided the speed is maintained at around 70-75 KMPH with the tacho hovering around 1500 RPM.
The above 26 KMPL average can be achieved (if one has the patience to drive at that speed on the highway) without resorting to any tricks what-so-ever. This is with AC and passengers and luggage in the boot. So the ARAI figure posted for the Honda City Diesel is very realistic and easily achievable.

In fact, all single divider-less highway drives where I usually maintain the speed at 80KMPH or below consistently gives 24 to 25 KMPL.

Its only on the 4 or 6 lane highways, the average mileage reduces in the following manner (all figures with AC and car loaded).

Driving around 80 KMPH gives around 24 to 25 KMPL average
Maintaining Speed at 90 to 100 KMPH gives 22.5 KMPL average
Speed at 110 to 120 reduces the average mileage to 20.5 KMPL.

Realistically, on 4 to 6 laned highways, you'll end up with around 20.5 KMPL mileage or 22.5 KMPL average round-trip figure (if you have efficiency in mind without getting frustrated about low speed on fantastic roads). Its the single laned (divider-less highways) where the efficiency is fantastic (24 to 25 KMPL) due to the lower speeds.

While driving in the City (without AC usually and sole occupant in the car). The mileage in light traffic (Covering 10 KM in 15-20 min) is 19 to 20 KMPL.
If the traffic is moderate to heavy (covering 10KM in 30 min) mileage averages to 17.5 KMPL.
In Heavy traffic (10KM gets covered in 1 hour +). This is the scenario in Bangalore these days. The average mileage returned is around 15 KMPL which is impressive.

It is pretty impressive the way Honda have engineered this fantastic All Aluminium 1.5 L diesel engine in the Honda City. 80% of the 200Nm torque gets delivered as early as 1100 rpm. This makes the City drives effortless and with minimal change of gears and ensures good efficiency. The turbo kicks in early at around 1500 rpm with a very linear torque delivery and is very drive-able in the 2000 to 3000 rpm range which is what most sedate drivers will use in the real world. I usually find myself between 1500 to 2500 rpm band during most of the time.

Your Verna FE must have been much above 18.5. I say this because you could not have consumed 43 litres (Full Tank Capacity) in a tankful method, or even if you ran the car out of fuel.

The max capacity is 43 litres and if you refilled tank somewhere around the low fuel warning, Verna accomodates only 33-35 litres.

Hope that brings more cheer to you

What I do is always fill the tank till the fuel is visible near the fuel knob. Run the car and fill again till the same mark. I usually fill when the last bar on the fuel line starts blinking. At auto cutoff, it gulps in 38litres.

So I don't know if that counts as tankful method. Confused 😳

Please avoid such methods
1. Filling the fuel tank to the brim will leave very little room for the fuel to expand. It's more dangerous in a petrol vehicle than in a diesel vehicle. Rather stop filling as when the nozzle 'cuts off' supply
2. Don't wait till the last minute to fill the tank. Your fuel pump will take the beating and its life will be shortened. Also if any impieties are present in the tank, that will also get sucked into the fuel lines. It will nullify all the savings you made by driving sedately. Instead fill up when the needle points at the last quarter of the gauge.

Just recorded the best ever figure on my '13 Scorpio 2.2.

Delhi to Haldwani - 13.7 kmpl! I was astonished as I wasnt expecting it. I was prepared for anything between 10.5 - 12 kmpl.

On return, the b2b congestion at Bilaspur and Delhi killed it. Got ~11 kmpl.

Honda City 2015 Petrol
2nd Servicing Done
Total Run: 6800kms

Got amazing Mileage today on my ride from Khunti to Jamshedpur. First 40km stretch is very nice, it is very slowly going down with small curves. I got a mileage of about 28kmpl for this stretch.

Then the rest 80km was a 2 laned road with full of patches, bad quality road. Mileage dropped on the way home from 28 to 23.3.

Jharkhand road quality is horrible, so we drove at speeds of 60-70kmph mostly and most of the time I switched on Cruise Mode.

Total distance: 125km and mileage of 23.3 on Petrol.

Although while going from Jamshedpur to Khunti, we got a mileage of about 18kmpl as Khunti is at a higher height to Jamshedpur. So average up and down would be somewhere around 20.5-21. Thats nice because ARAI shows 18kmpl and I'm getting 20+ with the help of Cruise.

I feel mileage has seen some improvement after 2nd servicing.

You sure you calculated right?
A petrol? You have got to start a thread on your driving style!!

This is probably the first car on the forum thats giving more than what ARAI "guesses".
