Default 1.4LT (LUJ) ECO -- FYI note!

It's the same engine, but there are slight differences between the output of the 1.4LT engine with 6-speed automatic (6T40) transmission and the ECO 1.4LT engine with 6-speed manual (M32) transmission:

Horsepower -- Applications:
Chevrolet Cruze LT/LTZ/ECO...138 hp (103 kW) @ 4900 rpm.

Torque -- Applications:
Chevrolet Cruze LT/LTZ.......148 lb·ft (200 N·m) @ 1850-4900 rpm.
Chevrolet Cruze ECO..........148 lb·ft (200 N·m) @ 2500-4900 rpm.


Although the above hasn't been seen on the GM Cruze site, it *is* contained in the GM-Powertrain documentation.

What causes the differences in torque between the LT/LTZ and ECO?

..."loading" of the engine by the automatic transmission torque-converter.

so of the two MH8 alxe ratios, one will be a bit quicker off the line and one will be better on gas?
