Different lbs/ft Torque!

[Liam40]

Hi,

Can anyone tell me the true lbs/ft torque of the Focus 1.0l EcoBoost 125bhp. When I browse websites, I’m getting two different specs! One is saying 125 lbs/ft of torque and another is saying 147 lbs/ft of torque. 

Which is the true spec?

Thank you,

Liam.

Actually both are true.

The 125 HP version of the 1.0 ECOboost has 170 Nm (125 ft lbs) of torque between 1500 and 4500 RPM during normal operation and 200 Nm (147 ft lbs) of torque in overboost. The overboost function is available for a maximum of 30 seconds. After releasing the throttle pedal (for example when shifting gears) the overboost function will be available again. 

The 100 HP version only has 170 Nm (125 ft lbs) between 1500 and 4500 RPM of torque and no overboost function. 

 

Note that the 1.6 Zetec S(E) (focus MK1) only has 145 Nm (107 ft lbs) of torque at 4000 RPM and the 1.6 Duratec (Focus MK2) only has 150 Nm (110 ft lbs) of torque at 4000 RPM.

 

Note that the listed power and torque output of the 1.0 ECOboost is based on RON 95 fuel. My experience is that the usage of high octane fuel seriously improves the power and torque output of the 1.0 ECOboost. I only use RON 98 fuel or if available even higher ocatane fuel. In the past my 125 HP 1.0 ECOboost Focus MK3 turned out to be even quicker than a 2.0 Duratec Focus MK2.5.

Right ok. So am I right in saying that some websites display the normal operation of 170 Nm (125 ft lbs) of torque between 1500 and 4500 RPM, and some websites display the 200 Nm (147 ft lbs) of torque in overboost operation? But in effect, it’s the same power output (bhp & lbs/ft) in the 125bhp version of the 1.0, from 2011 to present day?

I’ve always used 95 octane unleaded, never thought of using the 98 octane! Think I’ll try it at my next fill up.

Since the introduction of the 1.0 ECOboost in 2012 all 125 HP versions have 170 Nm (125 ft lbs) of torque between 1500 and 4500 RPM during normal operation and 200 Nm (147 ft lbs) of torque in overboost.

There is no difference in torque output between the MK3 and MK3.5.

 

I only use RON 98 for over 10 Years now. It makes the engine run a bit smoother while the fuel consumpion is slightly lower. In the end the running costs will not be much different between RON 95 and RON 98 fuel. However I my opinion a modern turbocharged petrol engine benefits more from higher octane fuel than the old naturally aspirated petrol engines.
