SIAM / ARAI Fuel Efficiency Figures (Now with Jan 2011 Data - pg6)

100BHP · 1st June 2010, 16:33

Values shown in the chart are test values of Chassis dyno during emission cycle. Values are normally similar to test cycle, provided vehicle is driven in similar manner by keeping in mind to get best mileage and taking all benefit of DFCO logic

DFCO = deceleration fuel cut off / no fuel is consumed during this mode (when you are driving and on seeing red light / stop distance just release accelerator pedal. DFCO is activated in following conditions ----Vehicle in Gear, clutch pedal not pressed, Accelerator pedal position is zero / no foot on clutch & accelerator pedal.
There will be no fuel consumed till the vehicle reach ~ 30 kmph speed OR any conditioned mentioned is changed. When vehicle reach low speed the fuel is started again to avoid engine stall / to avoid jerks. So you can feel this working in very sensitive way and can observe fuel restarting while reaching lower speed.. Distance covered in this way is with zero fuel / far better than neutral. In one liter of fuel you can save 2 ~ 3 km which is direct mileage increase. You need patience driving and planning and slowly this will get into your driving habits.

Cheers and save fuel by using this logic.

is SIAM US based ? if not , why they use "gasoline " instead of petrol ?

Either term is correct. They probably referred to it as Gasoline right from the start.

Hard to believe these numbers. According to it i20 is the most fuel efficient premium hatch and no one I have come across including the one's on tbhp has quoted more than 11-12 kmpl city figure, Swift and Ritz are more efficient in the real world.

2) 800 is less fuel efficient than the more powerful and heavier Alto and even the Swift and the Ritz!!!

3) Tbhpians have quoted mileage figures which are more than what SIAM says for the Linea. (Arent there supposed to be the absolute best numbers in ideal conditions?)

Because in technical language, gasoline is more commonly used.

Pick up any text book on IC engines and you'll see word "gasoline" all over and never "Petrol".

Thanks! I've been what the technical term for this was since quite a while.

We've discussed this quite some time ago here : LINK

Will this be based purely on speed, or RPM(ie gear) as well??
Isn't 30kmph fairly high? I'd imagine it would be a lot slower (assuming a low gear).

I completely agree with you.Real life scenario is different.I go for the Team-bhp figures which are more realistic.

Hi Guys, Can anyone confirm if the original Kappa engine (year 2008-2009) was BSIV rated?

I am still seeing Figo reflect marvelous figures in the SIAM FE list. which none of the owners have reported till now. Isnt that strange.

Guys, dont think we should keep criticizing SIAM so much, atlest they test all the car under a constant condition.

Imagine if there is no org. like SIAM to give out the figures, only other resource would be the car FE as quoted car ads. Lucky we have some neutral orgn. which takes care of this job. With no bias.
