2006 Aveo with manual trans = 26/35mpg
2007 Aveo with manual trans = 27/37
2006 UK/Euro Aveo w/ manual trans = 31.7/52.3mpg

GM and other American car companies are getting slammed for selling gas pigs while Toyota (who total fuel economy avg. is lower than ever) is the hero for selling 45mpg cars like the Prius and 39 mpg cars like the Yaris and Corolla.

We get the 1.6L 103HP engine here, they get the 1.4L 69kW (100HP?)

0-60 is 10.8 sec for the US car and 11.1 (to 62mph) for the Euro car. The 1.4L is Euro IV emissions spec. Why is GM keeping this high milage engine out of the USA?

A 50mpg gas Aveo for $12,000 would be the hero of the American car industry. Aveo is already the #1 selling sub-compact, just imagine if it could get Prius milage for 50% of the sticker price. They wouldn't be able to build them fast enough.

 

Imperial gallon and imperial MPG are different from what we use in the US.

The 1.6 would get about 42 mpg. And with 87 hp I don't think it would sell very well.

convert from kw to hp

 

hmm.... that makes more sence. It's not a magic 50mpg 4cyl

Either way it still gets 5.6L/100km thats about 42mpg for the 1.4L in the US. It would make a nice optional or base engine in the US Aveo and be ahead of Toyota and Honda. I'd like to see GM's 1.2L or 1.4L Ecotec with DI eventually used.

 

With the Civic getting 40 highway with 140 hp, I don't think that would be a winner here.

 

It would be better than getting 37mpg and 103HP THe Aveo should be a 40mpg+ car period.

 

With the horsepower disadvantage, no. If they can do it while maintaining or increasing horsepower, yes.

 

I agree, it should do better. On the other hand, both the Fit and the Yaris (and maybe the Nissan Versa?) fail to beat the MPG offered by their next step up counterparts. I wonder if the tall shapes hurt them enough aerodynamically to cause this. But I think the Civic outdoes the Fit (or at least matches it), and I think the Corolla outdoes the Yaris.

I'd like to see a ~1.8L version of the Ecotec show up in the Cobalt/Ion, with ~140 hp and ~40 mpg highway. The 2.4L offers ~170 hp, and achieves the same good, but not excellent, fuel economy that the 145 hp 2.2L delivers.

 

+1.

 

Those figures aren't even 'real world' imo.

I drive a 2005 Aveo w/auto.

I get 23 or 24mpg city. On a day when I did a fair amount of highway driving the most I managed was 26.

This engine is weak enough. I wouldn't consider something even weaker regardless of gas milage...

 

That is pitiful. That car should be getting better than what the epa rates them at. You would be better off to get a larger car and only lose 1 or 2 mpg.

 

Trust me. It's something I realize.

Though the price of the Aveo at the time I bought it made it attractive.

And now, with it upsidedown (by at least $4000) my options for a new car are limited... I could easily get a new 300, Charger or Dakota with the Employee Pricing Plus. But that extra $4000+ pushes whatever I get into a payment range I don't want.

Of course, there's also the concern that the Camaro will come out sooner than expected and I'm stuck in a new car payment. Chevy REALLY needs to announce something soon. Otherwise I'm gonna forget about a new Camaro for a few years and just get something nice now. An announcement of what model year it will be would be enough. At least I'd have an idea of whether it will benefit me to get a new car or not...

 

Its almost like something isnt right with the vehicle. My Cobalt matches or exceeds its ratings but its a 5-speed. Highway is closer to 36-37mpg from its rated 35 and about 25-26 city from the rated 25. GM needs to fix the city fuel economy badly. 25 is absolutely pathetic IMO. I almost feel like its not even worth driving such an underpowered car. I'll take a 4mpg hit and drive something with over 100 more hp anyday given the choice.

 

What kind of trannies are offered in the Aveo? I'd be curious to see what kind of rear gears and tranmission gears are offered. You could always get more mpg out of a swap of gears or different tranny (though it would add cost). I've always wondered why the Aveo did so poorly on economy in comparison to its classmates.

 

I don't know, but a lot of the engines I looked at on GM Euro sites are 10.5:1 CR

 

LoL, then why not get the Cobalt SS/SC? That seems like exactly what you need. Even with Stage 2, i actually brake in to the 30's (and occasional 40's) on the highway. City driving takes its toll because i have a lead foot and i average about 26 alltogether.

The only problem is under hard acceleration you can easily drop into the teens. Hard working blower = gas hog. And a 13 gallon tank doing 19mpg is not good.
