Thanks for sharing. That's a good comparison - the polo is at least 100 kg lighter, and has lesser coefficient of drag. I'm not that disappointed.

So, I'm not too far off with my driving style. BTW... if FE is such primary concern, I would have gone for the 1.5 TDCI (no 1.6 option on the ecosport, remember?). I've driven 500km in a week because it's a new car. Otherwise, I expect to drive less than 150km a week under normal circumstances.

Thanks for sharing. Again, the fiesta is about 130kg lighter, and will have less drag. So, that's a good comparison.

Am taking delivery tomorrow. Incidentally it is a White Ecoboost. |
Well, I guess you'll have to "reset your expectations". Your comparison should be with another engine that delivers 125 bhp and 170 Nm of torque - the closest is probably the Hyundai Verna (123 bhp and 155 Nm of torque but weighs 10% lighter, and has lesser coefficient of drag). If the mileage of the ecoboost matches that of the Verna (reports say it's between 11-13), you've got what was promised.
Well, a wise man once said that the biggest factor for FE is the driver. So, maybe it works out. Never-the-less, the mileage isn't a "deal-breaker" for you, otherwise, you would surely have opted for the diesel.

On highway alone i guess one can expect FE figues of a 1.2L hatchback.
BTW 11.45 KM/l with 65% city and 35% highway is decent figures by petrol engine standards.
The last petrols i drove were 1.6 Ikon and 1.6 Optra. Both never used to cross 10KM/l in city(not a bumper to bumper) traffic. It used be somewhere around 12-13 on highway.
Also have seen couple of current hatch giving 11-12 on long drives with five people on board.
Let me also Bring up one more observation.
Lesser displacement doesnot always mean better FE in all conditions. Below are few instances:
1.We were on trip to Ooty on two cars, Ikon 1.6 and 1.3. Since road has lot of ghat sections, 1.3 needed lot more gear changes. End of trip 1.6 gave marginally better FE than 1.3.
2. Our friend used to have a Optra 1.8 when we had 1.6 . In city both used to deliver almost identical figures, its only on highway where gear changes were less, 1.6 delivered better FE.
Going by the above data i would rate 11.45KM/l as decent FE. |
I agree with everything you say. Considering the additional weight and drag, and considering the FE will improve over time (engine run-in, and driver run-in
) I think the ecoboost engine will deliver what it promised.
The technologies (turbo-charging, variable valve-timing, direct injection) are geared to delivering low-carbon emissions (eco) and improved performance (boost) and of-course refinement. Design improvements to deliver higher FE have been compromised (low friction piston assembly, but the car has more drag. The engine weight is low, but the car is heavy, hopefully for a good reason).
The turbo-lag is livable. It's not like the 110bhp duster, where you're greeted with a dead response at 1500 rpm. I can potter about in higher gears at as low as 1000 rpm. In bumper-to-bumper traffic, I stay in 2nd, slip the clutch and use the breaks to control speed. I only
have to downshift if I need to quickly close a gap, and it's not something that has to be done all the time.
My frustration with the turbo-lag was due to my earlier car - the 1.1 liter i10. That engine had enough torque on offer even at 800 rpm (provided I'm driving alone). I'm learning to change my driving style now that I have a much heavier car and every passing day makes the turbo-lag less of a bother.
