Interesting, the new 2.0 liter has almost exactly the same power numbers as the old 2.3 which used to be in the Mazda3 s models. Consider the following:
 
----------------------- 2009 2.3 liter ---- 2012 2.0 SkyActiv -----
 - HorsePower: ---- 156 6,500 ------- 155 6,000
 - Torque LBFT: ---- 150 4,500 ------- 148 4,100
 
Given that the output numbers are almost a statistical dead-heat, and given that the SkyActiv motor produces its peak numbers at lower RPMs, my bet is that, all else being equal (which it rarely is), the 2.0 liter SkyActiv motor would actually "feel" faster.
 
As a point of comparison, even though the Chevy Cruze "only" puts out 138 horsepower, by virtue of its forced induction it twists out some 148 LBFT of torque at an extremely low 1,850 RPMs, and as such, even though it has by far the smallest displacement of the group, it might could well "feel" the quickest (once again, all else being equal).
 
Given that I didn't get a chance to drive either the Cruze ECO 6-Speed or the Mazda3 SkyActiv 6-Speed, I can only speculate on the above.

When I drove it last week, our '05 2.3 car felt livelier and had more torque...it just feels faster when you push the accelerator...even my 1.8 in my Civic seemed to accelerate faster! The Verano is looking better and better to be really honest!

Hmmm, sounds like the SkyActiv automatic transmission is so heavily optimized for fuel economy it refuses to gear-down for a little spirited performance. Remember when I said, "all else being equal"; apparently the transmissions are far from that.

#797 of 896 coolant temp gauge never goes above 1/2 by gpara

Dec 26, 2011 (8:29 am)

Hi group I was working on my 2011 cruze eco and was checking the calibration marks on the gauge, it starts to move at 120 and each mark after appears to be 10 degrees to 1/2 scale which was 198 but I noticed that the temp kept getting hotter, using scan tool to check temp, gauge stopped at 1/2 and never moved about, I let temp get to 235 before cooling fan came on and gauge still showed 1/2 or 198. I unhooked temp sensor and it showed -40 and shorted which showed 289 degrees F which all seemed normal. What good is the gauge if won't tell you that the engine is getting hot?????
Any else notice this, I have 7k miles and never has it gone above 1/2 or will it drop down when running cooler as thermostat opens ect.
This seems to be a software problem, since the gauge is run from the serial data from the engine computer????
Any comments???

gpara, as far as i understand, typical vehicle coolant gauges are programmed to behave exactly as you describe. they are not meant to read as linear gauges. the reason is to reduce the number of customers thinking something is wrong when coolant temp is within normal range, and costing service/warranty $ when there is no problem. in other words, knowing the real coolant temp can be considered "too much information" for the average driver.
to see the real coolant temp, possibly you will have to start the car in a way that enables the dashboard's diagnostic mode, and then find the coolant-temp screen via some menu. not sure if there is a way to do that on cruze but if I find out, I will follow up here. On my pontiac the way to do it is to start the engine while holding the dashboard 'mode' or 'set' buttons down.
also to nitpick, I'm sure you already know that the gauge is neither measuring engine temperature nor oil temperature - it is measuring coolant temperature.

Simple answer, your car (as with virtually every other car these days) has want can euphemistically be called an "Idiot Gauge". Said gauge is slaved to the OBD-II system, and as long as the coolant temperature is within the acceptable range, the gauge won't move from the "normal" position. The problem with such gauges is that when things start getting too hot, you see normal-normal-normal-tooeffinghot!

 If you had read CAREFULLY, you'd noticed that I do NOT have a problem with Koreans eating dogs, it was the "treatment" of the animals prior to slaughter that my was my issue.

"I think you have made it clear that you have an issue with at least one country... which might be coloring your opinion of their cars? "
 
Yes, in the respect of the [IMHO] inhumane treatment of the canines, I do reserve the option to be "opinionated" against Korea's auto industry.
 
Also, my 3+ decades with Southern Company, and the over 10k employees who post on intra-net boards and personal contact, has led to insight regarding most vehicle makers.
The Koreans MAY have improved quality, but in the first decade or so, the build quality was somewhat reminiscent of the Yugo.
 
A discussion of this nature could also point the finger inwards, as WE, the police of the world, maintain our "Right-by-Might" to pursue High Seas Piracy,
 
[and 20 gazillion other World Court & Geneva Convention Rules violations]
 
 by boarding vessels in international waters and seizing cargo supposedly bound for the USA.
 
One particular incident comes to mind.
"1500~ Miles off the coast of Manila, the US Coast Guard seized some tonnage of Cannabis bound for the US"
 
Two things really bother me with our actions in this case.
1 - The US' territorial waters do not extend quite that far
2 - Why is the "US Coast Guard" involved with drug interdiction half way around the world ?
 
All of this is waaaaay OT, sorry for the rant,
I'll get off my soap box now
 
Kudo's for calling me out on this or any subject BTW

Call me weird, but in forums like this dedicated to talking about cars, I like to talk about... CARS. If I want to discuss inhumane treatment of animals or action on the high seas, I know there's likely multiple forums that cover those subjects.
 
For example, I could say the Cruze is CRAP because everyone at GM is a lying, coniving thief who stole billions from US taxpayers. Now, that statement has NOTHING to do with the Cruze itself, and I don't actually think that way about GM and its loan from the Feds. But it's an example of how discussions like this could dive off into the deep end with irrelevancy.
 
So, let's talk about cars, shall we? I've noticed you have lots to say on that subject.

You have your opinions, and I have mine. I think the US will be found to be a terrible bully in the future history books, but that as you say is neither here nor there.
 
The vehicle choice discussion reminds me of an old saying;
 
"That's why God gave man a choice, Ford or Chevrolet"
