The more I drive this car.... The more I want to drive it

Could you tell me what rpms you were at?

The highest I have got was close to 20kmpl one time and that was by keeping the speed at 100 kmh with great difficulty for a distance.

Yeah I'm interested as well in rpms. It's not exactly the same car but my ES TDCi drops FE like hot potatoes the moment I get even a little bit heavy with my foot. It's best driven at 80-100 KPH at around 1900-2200 rpms in 5th from my experience. Anything above 2.5k and you see the FE hit.

Mine is the ambiente variant, so no tachometer for me but I guess the RPM was between 2500 to 3000 RPM and if I'm not wrong, 100 comes up at close to 2200 RPM. Speeds were <100 from Surat to Vapi and from Vapi to Thane was 100 to 120, depending upon the traffic. While on the expressway it was different ball game all together

As mentioned earlier, my car does not have a tachometer so can't give you the exact RPM but approx figures are given in the above post.

Agreed to your point that fuel efficiency drops post 2500 RPM but by then you already reach 120 kmph. My uncle too has EcoSport diesel but even though it shares the same engine as the Aspire, fuel efficiency is nearly down by 4 to 5 kmpl in the EcoSport. This I'm saying after a trip from Bombay to Rajasthan wherein the speeds were in the range of 100 to 120 kmph and we managed a FE of 16 kmpl for the entire trip.

I have got a mileage of 32 kmpl (without AC) on an expressway with speeds not more than 90 kmph. I on purpose drove it with an intention to keep the car just between 1800-2200 RPM so that the torque helps the car to keep motion.

This was around 150 KMs and with the only intention to check what best mileage the car can return. I had a pic which got lost due to a factory reset.

Another instance was a good 1500 kms drive from Mumbai to Goa and back. In the entire trip I managed to get an average of 22 kmpl with 90% of the time having the AC switched on. Maintained good speeds of about 100-120 kmph on highways and drove enthusiastically on the curvy roads of Konkan. One of my finest drives till date and all thanks to my Figo S TDCI.

It is a different figure when you check by tankful-tankful method which is what I go by. The figures showing on the MID depends on your accelerator input and is an average since you last reset it.

All the figures I quote are from tankfuls and is an average over varied driving conditions. If I drive from bunk to bunk on a highway with less traffic for 100 kms at 100 kmph, I am sure I can get a good efficiency figure as well

I filled the tank with first cut at the start of the expressway and after driving for nearly 150 kms, on return filled it again till first cut at the same fuel station. This is how I calculated the mileage of 32 kmpl. But as mentioned earlier, it was purely an exercise to know the higher limit of the car. I drove it like a baby cart is pushed. Avoiding braking, using engine braking, no hard acceleration and cruising at 80-90 kmph with AC switched off.

Recently I did the same exercise but drove the car like I usually do. I have a bad habit of excessive braking which I am trying to rectify. TFTE method gave me a mileage of 17.5 kmpl with AC and some really enthusiastic driving.

I have done this exercise quite a few times and with varied driving styles and road conditions. I am highly impressed with the TDCI engine. It has never given me anything less than 17 kmpl till date. Mind you I live in Mumbai, so even in bumper to bumper traffic the engine has not been a skinflint.

One friend had a noise issue at slightly higher speeds. The Ford folks found a leak near the headlight which caused the issue and rectified it.

Sames goes for the Old Figo 1.4 TCDi Engine, 2200 rpms is the max for milage, could be due to the SOHC nature maybe?

Did you get this modification done? My Ford SA said it can't be done! Exploring possibilities to get a reliable android unit without losing the audio quality.

He didn't get back. I guess he realised later that it can't be done.

To contribute to the FE topic here, I have realised that my Figo 1.5 TDCi returns better economy when driven on the highway at a steady 115-120 as compared to what it does at 80, and for good reason. Allow me to elaborate.

The TDCI is a powerful motor and I have distinctly felt that the gearing on the 2019 edition is taller than the pre-facelift. The engine is barely in the turbo zone at 80kmph in 5th. There is very little incremental fuel/km used at 110 as compared to 80 due to the better efficiency in turbo zone. Where it actually helps is it takes less time to cover the same distance.

The time taken is important because the fuel consumed by the Aircon is not a function of speed but that of time. As you might have seen when idling the car, it takes an additional 0.4l/hr of Diesel for the car to idle with Aircon on vs off. This figure, I have seen, does not change too much whether the car is running or stationary.

With a cruise speed of 80kmph, on ~200km 5 hour journey, the car will use up 2 litres just to keep the Aircon running. If the car returned 20kmpl on a 5hr 200km journey, i.e. 10l of diesel, it means it used 8l for moving the car and 2l for keeping the Aircon running. Without Aircon, the same journey could have been done at 25kmpl.

BUT, if you cover the same 200 km at a higher cruise speed and end up covering the distance in 4 hours, that is a saving of 0.4l on just the Aircon. Coupled with higher efficiency of the engine in the meat of turbo zone, the additional frictional losses due to wind resistance can be mitigated. This reduces the consumption to 9.6l for 200 km or roughly 20.8km. I have seen this figure increase to 22kmpl in such a situation.

I have even tried the pulse and glide hypermiling technique but haven't been able to beat 120kmph 22kmpl with Aircon. But the one time I tried driving without the Aircon on an early morning drive, I ended up with this when I was parking the car by the end of it.



This was without even having to try too hard. At some times, it went all the way up to 27/28kmpl just before I hit Hinjewadi morning traffic. I had covered the 200km from Nashik to Pune in 3 hours that day. The only thing I did differently was turn off the Aircon, set the temperature at 20degrees and switched the airflow to fresh air to let the cool morning air in.

I have done the same ~200 km stretch of Nashik- Pune highway at least 15 times trying various cruising speeds just to figure this out. I hope this analysis helps someone someday.

The photo was taken back in January when it was still cold and people could still drive as much as they wished. Here's hoping we can get back to the good ol' days soon...

Interesting analysis.

On my car, once I cross 2k rpms, the max I can get on the MID is 20 kmpl which in reality may be around 17-18 kmpl. I have never checked without AC, so all the figures are with AC running.

There was one surprise on a trip to Chennai from Bangalore were I tanked up with around 60-70 kms left to Chennai which is the busiest stretch of the whole journey. I reset the MID after topping up and drove that last stretch not crossing 2k rpms and mostly around 90 kmph with AC and with gentle accelerator inputs and trying to coast wherever possible. The MID showed 33.3 kmpl and didn't go above that.

I did it only to check what was the max I could see on the MID. I had half a mind to top up the tank at the end of the journey just to see what the reality figure would be.

There is also a downside to driving like that on the long run, which is clogging up the engine internals and exhaust system with soot. But that can be sorted with some spirited driving once every few 100 kms.

What's the kmph/1000 RPM for 5th gear? In other words, what is the RPM at 100/120 KMPH in your car?

I used to own the pre-facelift version and the short 5th gear (100@2500RPM) meant that I never wanted to cruise above 90-100 just to avoid that drone. It seriously needed a 6th gear or just a super tall 5th gear given all the torque available from down low.

I don't remember the exact RPM but I do remember how the Zoomcar Figo that I have driven at least 3 times on the highway would pick up speed in 5th all the way to 80kmph. My car doesn't do that, but it does pick up speed incredibly well when going 100+.

Unfortunately, the Zoomcar Figo (pre-facelift) was speed limited and wouldn't breach 80 so I cannot compare apples to apples in the 80+ range but within that range, the Pre-Facelift was definitely faster AND more efficient.

This brings me back to my original analysis, since the Zoomcar Figo had shorter gearing, it would be in the meat of the turbo zone at 80kmph (where I would invariably be when cruising) whereas in my car, 80 is hardly turbo zone. The Zoomcar would return incredible efficiency at those speeds, in the region of 22+ as far as I remember. My car gets the same numbers at 100kmph but in the 19-20 range at 80.

Please note, all of the above are highway FE figures from the MID with AC ON. Next time I get the chance, I will note the RPM at 100kmph in 5th but as far as I remember, it is definitely lower than 2500 RPM. All I remember is how it launches itself to the 120s and the irritating beeps start as soon as I push the accelerator.

I got the chance to drive out today.

The following were the RPMs in 5th gear for the corresponding speeds.

60kph -> 1250 RPM
80kph -> ~1700 RPM (mathematically, should be 1666 RPM)
100kph -> ~2100 RPM (mathematically, should be 2083 RPM)
120kph -> 2500 RPM (did not check this, extrapolating from the previous values)

From what you have given, we can get the following in 5th gear for the Pre-Facelift Figo.

60kph -> 1500 RPM
80kph -> 2000 RPM
100kph -> 2500 RPM
120kph -> 3000 RPM

So the gearing for the 5th gear is about 20% taller in the 2019 edition.
