What is the difference between e-tech ii and ecotec for chevrolet aveo?
I was curious about this at first too. I did some research and found my information via the links below. I don't like the fact that the "e-tec" name infers that it is a shortened name for the "eco-tec" to the uninformed consumer, which is a more recent and superior engine.
The E-tec II is a GM Family I engine and the Eco-Tec II is a GM Family 2 engine. Info below.

The eco-tec is just a newer engine design with more technology built into it. When I got my 2005 Aveo I was pretty surprised at how little technology it had. No variable valve timing was probably the biggest thing. The e-tec II's compression ratio of the engine is also pretty low compared to the eco-tec at 9.5:1 vs 10.8:1. The eco-tec is also a much more efficient engine as you can see from the mpg ratings of the 1st vs 2nd gen Aveos.
Okay now I have an Idea about the E-TECH II VS ECOTEC
WHICH OF THOSE 2 ENGINE IT HAS MORE HORSE POWER E-TECH II OR ECOTEC?
So that's mean that ECOTEC is not on 1.6L version anymore?
