Swift Petrol vs Diesel - is saving the ONLY reason?

No AMi,on comparing the two cars (keeping the driving skills constant ofcourse),The Petrol will always be the winner.

@Raj,about the environment part i totally agree.we all must play our part.

But we r moving away from the topic here,because Diesel in India is cheaper in India.

in Other Countries,Deisel is atleast equal (i repeat,ATLEAST,because in Australia its more expensive than petrol)

so in India,Diesel Users are just Lucky by CHANCE,they arent worthy of that credit which they our getting by being called as "environment lovers".

p.s-Diesel owners please don't get offended.i too use Diesel.But Diesel irrespective of its characteristics,is ONLY being used for the saving it gives.

Not necessarily, for the resons stated before (quoted herein below)...

On highways/long-drives, Swift diesel will have the advantage, as it has much better/higher roll-on accelaration - while the max. speed achievable by both is at par.

Yes, saving is a big/prime factor - notwithstanding the other benefits of diesel engine (discussed on numerous occasions).

This post is edited subsequently to correct the 2nd quote/name.

Pankaj, the 2nd Quote is not mine ?i am not sure, or was it from another thread?

And at highways too Pankaj,the Petrol Swift will reach te speed of 100 kms/hr, a good 1.1 seconds before the Diesel Swift.

So It will be ahead that means.

ALso PEtrol's top speed is a touch higher than the Diesel (2 kms/hr).So when the two cars reach their top speeds,the difference between both of them will keep increasing.

Now ofcourse if we are comparing ONLY the cars,and not the Drivers and there driving styles,then i see no reason why Petrol wont win.

If you guys agree to this point,then again,we get back to the original point,which says "Swift Diesel is ONLY for saving".

your views

Sorry for the error (the quote/name since corrected).

Swift Diesel will have advantage on account of roll-on accelaration, which will be required quite often (at high speed / without changing gears) in normal highway-traffic conditions (not express highways).  Besides, it has good pick-up as well (though lower than petrol).  Anyway!!

There are people who are not really concerned about running cost but are lovers of diesel engine for various other factors.  But yes, as stated before, savings is otherwise the prime factor - in general.

Hope someone else has some other dimensions to discuss (subject matter).

Let's wait

These days I suppose the reason must be the one Binoy posted in post #12.

Turbo boost.

This has made them equal to petrol cars. But this is something that most people dont know.

So I would say among all the reasons, Fuel Bill Savings is the buggest.

i think roll on Acceleration has its role in the discussion above.

However,i was trying to look at some Gear wise top speeds and times accordingly.

Because my question now is ,

Swiift Diesel's power is is 12 ps lesser than petrol.And also at lesser Revs per minute(4).

That means the Maximum torque wont hold any good after 4 RPM.Since if there is no power to back the Torque,there wont possibly be any increase in Speed,atleast at that particular Gear.

Correct me if i am wrong,its interesting to know your views on this.

Cheers !

Only that in real world driving its the torque that really counts. The increase in speed depends more on gear ratios rather than completely on the available power.

In, in gear acceleration terms the swift diesel is a scorcher-faster even than the mighty optra magnum diesel!

The torque difference between the diesel and petrol is 77Nm !! and the diesel maxs out the same about 2500rpm less than the  petrol.

The actual point is that in the diesel the driver does not need to rev the engine over 2000rpm to get max drive while in the case of petrol the driver will have to rev till 4500rpm and still get less torque than the diesel.

well i understand that part Binoy, But then that did not answer the question actually,

if there wont be any power,beyond a certain amount of revs,how would there be a faster car?

We are in the right direction,probably a little more research and a little more detailed discussion on it would clarify this.

Also, Binoy,i think the guy driving the Diesel WILL have to revv past 2,000 RPM to get that speed boost. We all can clearly Point out that if both of them start from Zero,Initially the Petrol will be ahead (in between i dont know what happens,i am only trying to talk about what the figures say,Ofcourse practical experiences are welcome).

Swift Diesel will have the benefit, as explained, because of much higher roll-on accelaration / torque at much lower rpm.

By the way, as far as Swift in particular is concerned, Swift Diesel is a much better car than Swift Petrol and, therefore, the fact is that many people prefer Diesel for its engine performance (notwithstanding the running cost).

well this is a debatable topic, i have already expressed my views over this. I think others should put in there views regarding Pankaj's last Paragraph.

This could probably be a hot question for "polls" but anyways.

Okay,So guys,putting it in another way-

Swift Diesel is preferred to Swift Petrol ONLY cause of the saving factor,Agree or Disagree. Please give reasons for your answers.

Cheers !
