media.ford.com updated the Technical Specifications for the 2011 Ford Fiesta
previously it said:

Horsepower [email protected] 6,000 rpm (Estimated)
Torque 109 ft.-lb. @ 4,250 rpm (Estimated)

and now it says:

Horsepower [email protected] 6,350 rpm
Torque 112 ft.-lb. @ 5,000 rpm

more power!

I wonder what it is that they are tweaking. Anyone have a dyno of the equivalent euro engine?

EDIT;

After looking around, these are the same numbers that the euro 1.6 Ti-VCT except the Hp peak occurs about 350 rpm higher and torque peak occurs almost 950 RPM higher on the NA model.

From a UK site;
120 hp at 6,000 rpm
152 Nm to 4,050 rpm.

152 Nm is equivalent to 112 ft.-lb

A little music for your ears.

If its making torque that much higher than the European counterpart than I'll be extremely disappointed. I really need to drive one to have a feel for the powerband, but on paper it looks pretty disappointing.

 

[BRGT350]

I also noticed the higher RPM for max torque, however, without seeing the actual turque curve, it would be impossible to make any judgements. Just because peak is located at high RPM, doesn't mean the curve is not flat.

 

[iamz]

Yeah, I didn't want to draw any conclusions about the overall torque profile. Let's hope that it is just extended somehow without losing torque in the lower rpm's.

 

[BRGT350]

with intake plenum changes, adjustment in the cam profiles/phase angles, exhaust tweaks, and PCM tuning there are a million ways to play around with the torque curves.

the beauty of the Ti-VCT gives the 1.6L a very well balanced powerband. In my Focus I find it very good/strong from 3,000-6,000 in all gears.
Love this engine.

 

[BRGT350]

I expect the Fiesta will be about the same. Good, flat power after 3k rpm. What will be fun is to see what FSWerks can do with programming to move the torque band thru cam phasing. Besides, look at the high RPM's the old VTEC Honda's required to make power, yet they are all quick on a race track. Personally, I am excited for the new numbers. With running low octane fuel, I thought the actual published number for the US car were going to be way under the EU version.

VTEC just kicked in yo

 

[BRGT350]

I loved going to autocrosses or track days and see ITR's, S2000's, and Si's when the VTEC kicked in. All of sudden the car got louder and quicker. Ford's Ti-VCT system is no where near as abrupt.

Just noticed Ford is running an 11:01 compression ratio on the Fiesta's 1.6 liter. My Mazda is 9.1:01 for comparison. It's pretty amazing that with modern engine controls Ford can do this without requiring 90 or 91 octane.
