I am gonna check it again this week, will post the updates, hope the new tyre improves the efficiency.

If its a difference of just 20 kilos, then you can't expect it to give better FE than the Fiesta unless there is some difference in gear ratios and ECU mappings to aid FE.

Well then atleast it should return FE figures similar to that of a Fiesta TdCi right??

Yes it should, provided they haven't played around with the gear ratios and ECU maps. A weight difference of 20 kg will have a very negligible impact on FE. The air pressure in your tyres will have a greater impact than that 20 kg weight.

I was being bombarded by a few fellow bhpians when I was talking and the petrol Figo's FE being on the lower side, so I left it at that, knowing fully that the ghost come out of the closet soon enough(ie the owners would speak up soon). That said, I never expected the TDCi to come out with such bad numbers. To be fair to Ford, I think we need to get some mileage on the engines (at least 5000 km) before we come to a proper conclusion regarding FE.

If we are used to petrol engined cars, the driving style is different for diesels and that too could have a negative impact on FE. You need to ride the torque wave here. No use in pushing up the rpm beyond 3.5k . This too is on the higher side. Best is to upshift around 2700 rpm. FE also takes a hit in bumper to bumper traffic.

Mustang or any one else can tell, have they made changes to the engine configuration to keep the cost low ?

Fiesta indeed renders better mileage than "so far" Figo figures. Even if we do not compare with IKON or Fiesta, is 12~14 kpl (100% in city) justified from a proven TDCi engine doing service into a 1130 kg hatch?

I agree to every word, i am new to diesel, however i follow the basic rule book to diesel.

Maintain the engine speed below 2700, upshift around 2200-2500 and hope it starts giving better FE with more numbers on the odo. also will take her to the highway and check.

[Brix]

For a new vehicle, I think the RPM should not cross 2000. And yes, upshift beyond 2000. That way it "almost" rides like a Petrol.

Next time round, I'll ask Ford to include this in the "Driving Skills for Life" program.

Longhorn,scorpio, brix are all correct in their views. My doubt is whether we need to look into rpm's while shifting gears. Is it not right to upshift early but without lugging the engine. - Need experts views on this.
When I drove indica first time it returned poor FE on a onward travel in a highway. During the return I did not pedal it sudden and harsh but able to maintain 90km/h throughout and got 20.5km/l.

I used to change gears below 2k but then suggestion from other diesel owners made me change the driving style. The idea is if your are shifting below 2k, the rpm will go below 1.5k lugging the engine. So now i drive below 2k most of the time and push the vehicle to 2.4k and shift.

Rightly said scorpio !

Mustang did a fantastic job by giving technical information to the forum members. Now i think low Figo TDCi FE is building into big storm. I am sure with Fiesta TDCi engine every body's expectation about Figo TDCi is very high including me

Fiat Multijet/Swift DDiS are proven engines, and so i thought Fiesta TDCi was. But now looking at the number of people raising concerns, I am wondering if the Ford engineers did something "special" to the TDCi before putting it onto the Figo ? Ford are you listening?

Also i was told by the ford support and service centers that these TDCi engines do not need run-in. They will give you same mileage from day one !

well to be honest, Fiesta engine pedigree is the reason for me choosing Figo, was hoping to get a similar mileage, hence did not go for a petrol. Hope my choice is not a wrong one, but again, i would wait for atleast 3 more tank fills before deciding on the FE.

Great report. I'm still confused about the mileage figures!

scorpio, for my usage petrol was sufficient, but fiesta TDCi reviews were so great that i bought a figo TDCi !

Time will tell how good/bad our decision was. I sincerely hope Figo TDCi will give same/better FE than Fiesta. If not Ford is in trouble, it would imply that ford has used some cheaps replacements inside the TDCi while plonking it onto the Figo. If Figo TDCi gives 2 kmpl less than Fiesta under similar conditions, Figo will see an early demise.

I need some tips from the proud Figo owners here regardind driving the diesel Figo, as this will be my first diesel car, so concepts like turbo, lag, lugging, torque, and when to shift gears are rather alien to me. I'd love to get the best from my Figo both in terms of fun, and fuel economy!

All absolutely correct. This inconsistent poor mileage figures creates jittery in my mind and making me to think of cancellation of my booking. But again doing a research, TD's, etc is something not to be experienced again
As said, Ford should come out if there is real problem in the areas of FE and clarify. If Figo fails in this FE test it will see its exit gate early as rightly pointed by Yamaha.
