1.4LT (LUJ) SAE power & torque curves

[70AARCUDA]

From GM-Powertrain:

• Manual Transmission

• Automatic Transmission

...notice the differences in the two torque curves, especially at the low- and high-ends!

Europe = 1.4L Turbo

But for Europe seems to be 1850 rpm manual.

I also checked in some brochures given by the dealer:
200 Nm@1850-4900 rpm in manual

Which 1.4LT engine-code does your Cruze S have: LUH or LUJ?

Over here, our 1.4LT engines have codes LUJ (2011-2012) and LUV (2013).

This is LUJ. No other applications of 1.4T in PL Cruze.

...here's earlier post about the 'difference' between the LUJ and LUV engines: http://www.cruzeforumz.com/f12/1-4lt-luv-vvt-dohc-seq-mfi-new-190/

I find that the difference in MPG when using higher octane becomes more apparent with more displacement. The larger American V8's I find will gain 10-15 HP with higher octane fuel. That extra power through the RPM range technically could allow the engine to operate more efficiently if you don't need to get in to the pedal as much to achieve your desired speed.
