@sreenivass..the ikon and the esteem are really old cars...6 and 10years...although i have done a tune up for the esteem, she still gives an average of 6 not more in the city..same goes for the ikon 1.6..the black swift is always bhaggaoed..and the silver is driven by my mum.
Did I get that right ? Your 1100 cc heavyweight (compared to Alto) Santro returns more FE than your 800cc lightweight Alto ? Are you sure you posted right ?
I guess the Delhi/Noida traffic is lesser compared to other Metros and the roads are also better. But still, this is the 1st time I am hearing of city FE of 18kmpl for a Santro (eRlx or otherwise). This would be tough even for a M800/Alto in Chennai conditions. How do you measure the FE, BTW ?
Seems unbelieveable but it is true .... no mistakes here ...
I guess let me explain some of the conditions ...
1) Start for office at 7.30 AM little traffic on the road
2) Keep RPMs very low and shift to a high gear whenever possible
3) Drive 70kms (35 kms one way) every weekday
4) Use only IOC premium petrol
I measure FE by topping to the Full tank (1st automatic cut) ... reset the trip meter ... refuel again to full tank (1st automatic cut) ... divide number of kms on trip meter by fuel quantity.... I hope this is the right method
I can probably attribute the higher FE on Santro due to its high torque at low RPMs ... I am in 5th gear by the time I hit 50 kmph ...
While if I am using my Alto I can put it in overdrive only after I hit 65 kmph otherwise it just doesn't pickup speed... do other Alto users also experience this?
I had an 800 for four years and a half and I calculated FE for this entire period, i.e. the full fuel poured in during these years divided by the total distance covered during this time. FE came to 16.4kmpl. I drove about three quarters the time with the A/c on.
In my Petra 1.6, I have till now done about 1200 km and FE is hovering in the region of 9.2-9.5 100% with A/c (don't want to get the car dusty in this dry and hot Mumbai [winter]).
Of course, I have to admit that I am generally keeping the revs down, and except for a couple of occasions, have not let my heart overpower my head.
Which brings me to another point being discussed here- Below 1000 rpm, one just has to down shift one gear. At 1500, if one shifts quickly enough for the revs not to fall too far down, one can up shift comfortably (for the engine). But during all this, the engine only purrs like a cat, and there is none of the fabled roar of Ferrari's cousin tiger crouching under the hood. For that I shall wait for a few thousand km's more. Of course I have succumbed to temptation a couple of times, and my word, the sound- it is addictive. I have no idea if after I have run my engine in, I will ever reach double digits for FE. Not that I care, though.
1. At 23kms on Odo filled Shell Super upto auto cutoff, reseted trip meters
2. At 441kms on Odo filled once again Shell Supreme upto auto cutoff, with trip meters showing 418.5 kms, only city driving.
3. It took 28.56 lts @ Rs54.47/lt
4. So FE is 14.65km/lt, in Bangalore on Hosur road. Daily commute between Vijayanagar and EC morning around 8AM and evening around 7-9PM.
- Press clutch only when it is required to change the gear.
- RPM was maintained between 1500 to 2800 most of the time
- Never shift to 5th gear, unless car is at 70kmph and expects to drive at least 2kms at that speed, what it means is rarely I drove in 5th gear.
- Around 15% AC, as it is winter here in Bangalore
- Tyre pressure was around 36PSI, after driving around 15kms, so at cold it may be around 32psi.
with a light foot, and not exeeding the speed limit,in easy traffic(usually driving in late evenings) iv extracted 12 kmpl from a mercedes C 200 Kompressor, and 8.2 from the old Honda CRV over a tankfull. and 14 from a 1966 VW 1300 Karmann-Ghia, but there is no a/c in the ghia. my worst is just about 1 kmpl in a 1939 Lagonda V12. but i was revving it.
