Great to know that your FE is improving.
Me too got just above 18kmpl(18.2).
But that was only once and mainly highway usage and speed range kept below 80kmph for a 320km stretch.

WOW! really high figures!

I am getting an average of 13-14 kmpl @ 100% city driving and 80% AC

Mt car has crossed 2300 kms and the last time I did a full tank to full tank mileage test I got a figure of 11kmpl for 100% city stop and go driving along with 100% AC and also I do a compulsory 10 minutes initial warm up of the engine on idling first thing in the morning before moving the car.

Guys, if we look closer to Beat's Odo console from an angle, we can see Distance to Empty and Out side temperature options available. This features are not in Indian Beats. Can we some how activate it? Can we procure the required parts from other counties.

Cheers!

10 mins
I dont think it is really required.
You are wasting fuel!
Initial idling is required for Diesel vehicles with Turbo.
The idea is to get good lube oil supply for the Turbo, since the operating RPMs are extremely high(6digits). So there are chances of turbo failure if sufficient lube oil supply is not available.
But anyway few seconds of start-up idling is always good for any engine.
May be you can bring down 10 mins to 10 secs.
Definitely your FE will improve from 11kmpl.

BTW if it was me, then I would have covered atleast 8kms within that 10 mins.

Salbin is right. 10 minutes of idling is overkill.

More so in the summers.

2 minutes should be enough to rouse the engine and spread the oil evenly.

Even diesels don't require 10 minutes of idling! 4-5 minutes is enough.

IMO and from what I have read, the modern petrol engines need almost no warm up time at all. What you can do instead is keep the RPM below 2k mark for the first 10 minutes of driving. 10minute warmup is quiet extreme

my friend 10 min idling for a new generation MPFI STEC Euro iv 4 cylinder petrol engine is like 10 min x 365 equals to 3650 min per year .

if you cover around 1000 mtrs in 1 min you can cover 36500 mts in that time that would be around 3650 kms .

Assume FE of beat is around 15 kmpl that would convert to 243 ltrs of fuel wastage per year and your pocket hole would be 12636/ Rs .

i dont think any idling is required for the new generation engine .

I feel, sadly, nothing can be done,except wait and hope that GM would incorporate all these ( and many other missing ) features in the BEAT.May be after that you could swap the instruments, that too, if feasible.

What an amazing calculation this is. Great job.

Thank you all for your kind advice. Guess I am being too careful with my car or the lack of it
I shall henceforth not bother about the idling thingy to a great deal

It is probably due to the insufficient fuel supply to the engine during the start-up. Get fuel pump and fuel system checked at the ***.

Also follow the following procedure before startting the engine:

1. Depress the clutch
2. Turn the key to ON Position you will hear a humming sound of the fuel pump and will see red engine coolant temperature warning light on the instrument panel. Wait till the fuel pump sound and engine coolant temperature warning light goes off.
3. Turn the key to Start Position.

This is a must procedure to start a mpfi engine.

thank you rjvora

one more such interesting calculation goes like this

everyone thinks whether we should opt for a petrol or diesel vehicle , take a look at this example .

1. let us assume you purchase beat LS for 420000/- on road

2 . and let us assume other person purchase a ford figo diesel at 520000/- on road .

so here the pricing difference between the vehicles is around 100000/- that translates to around 1923 ltrs of petrol assuming the FE of beat is 15 kmpl it would cover around 28846 kms . before you can realize any pricing benefit from your diesel vehicle .

also if you run your diesel vehicle 28846 km you have to pay around 72115/- Rs. extra for diesel assuming a FE of 16 kmpl for the diesel vehicle .

again in the same 72115/- you can have 1386/- ltrs of petrol and run your petrol vehicle to 20802 kms

hence your petrol vehicle would cover 49648 kms , still the deisel vehicle would not have any price advantage over petrol vehicle .

so to get any real cost benefit from your diesel vehicle you have to wait for 3-4 yrs time period .

bottomline is petrol or diesel , does not make any much difference if you calculate the running costs and upfront payments .

That was pretty confusing.

Let me put it in an easier way.
Price difference = 1L
Assuming you travel 10,000 km/ year
Cost in beat = 10000X45/14(FE) = Rs 32,142
Cost in Figo = 10000X33/18 (FE) = Rs 18,332
Difference in Fuel cost. = 13,809
Interest on 1L at 5% = 5,000
Assuming maintainance cost in Diesel is higher by Rs2000/yr

Final difference = 14-5-2= RS 7K per year

Assuming resale of diesel is better than petrol by 30K

Break even point = (100-30)/7 = 10 yrs

That value of 10yrs will dramatically change once you change the distance travelled per year.
