Replying to: sun44 (Jan 25, 2008 5:00 pm) The Aveo is a descent car especially for the price. I see GM has said the 2008 model will have a 5 hp boost and expected 8% boost in mpg. That is good news for buyers. I wonder if they just tweaked the fuel injection?   I also find it interesting that a larger Chevy Cobalt frequently from what I read here and in magazines consistantly gets better mileage than the Aveo in both city and highway and the Toyota Corolla gets better mileage than the tiny weird looking Yaris as well. Something is wrong here. Replies to this message: wave54 (Jan 27, 2008 12:43 pm) poncho167 (Jan 28, 2008 5:49 am)

Replying to: poncho167 (Jan 26, 2008 5:09 am) Sometimes a larger, more powerful engine can produce better mileage because it's loafing on the highway and can get by with a more economical final-drive ratio. The 1.6L works too hard to accelerate from a stop and climb hills.   It all depends on the car, but it's not impossible that the Aveo could get better mileage with a 1.8-2.0L that has 25 extra horsepower.

Replying to: wave54 (Jan 27, 2008 12:43 pm) The city mileage is comparable between these cars as well.
#197 of 254 Early observation by timseh Feb 01, 2008 (7:55 pm)
I've only got 600 miles on my 08 LS Sedan (5 spd), so I know it's very early to be paying too much attention to my mileage. I did manage to burn off just over half a tank in mostly (85%) highway driving this week, though and decided to fill the tank tonight and see how I'm doing.   Just a hair shy of 35 MPG. I'm pretty happy with that, especially given the rotten mileage I've traditionally gotten in the winter here in Cleveland thanks to "winter gas".
#198 of 254 Only 25 mpg by intexas2 Feb 07, 2008 (9:33 pm)
New 07 Aveo5 with manual tranny. First fill up--only about 25 mpg. I'm disappointed. My 11 year old Geo Metro got around 35.   From what i can tell, the gearing on the manual transmission is the big culprit. I'm doing 60 mph and the engine is turning around 3K rpm. I keep wanting to shift into a higher gear, but, alas, there isn't one. My Metro seemed to cruise the highway at less than 2.5K, and that on a three-cylinder engine.   Why do they gear the 5th gear so low?   Replies to this message: poncho167 (Feb 08, 2008 6:16 am)

#200 of 254 Good mpg for '05 hatchback by nav7090 Mar 02, 2008 (12:24 pm)
I bought this throw-away car w/auto tranny and air in May '05 for about $8.9K out-the-door after using $ accumulated on GM credit card. 0% interest for 36mos from GMAC. Judicious tracking of mpg = 31.5 after 44Kmi. of regularly driving back and forth betweem 3000'msl and 100'msl. at 65-80mph. Change oil/filter every 3.2Kmi±. Am very satisfied with this commuter car, but am somewhat concerned with dealer&engine mfg.'s recommendation of power flush/replenishment of coolant after 36Kmi. I didn't want to spend the >$300, so I didn't have it done. Anyone know anything about this coolant system's weaknesses?

Replying to: nav7090 (Mar 02, 2008 12:24 pm) Not necessary, this is just a dealer service bonus. The cooling system is no different than any other small car. Just change the anti-freeze every 2-years and you will be fine. If it has that extended range orange anti-freeze that is good for 5-years.

Replying to: nav7090 (Mar 02, 2008 12:24 pm) I usually change my coolant or have it flushed at about every 30,000 miles, or about every 48,000 km regardless of what the owner's manual says. I do what is considered "severe" driving because I do mostly city driving with stop and go and very short trips. So, I like to service the car more often. It saves me money in the long run.
#203 of 254 GM can do better by nogmfan Mar 28, 2008 (11:02 am)
I was considering the Aveo5 to replace my '01 Echo so I rented one recently while on a buisness trip. The car had just over 4k miles on it and I had it for a week. I drove practically all highway miles and it averaged 27 US mpg. GM has to do better.   My Echo gets 40-42 mpg on average. I'm now considering a Yaris. Or maybe I'll hold on to the Echo a while longer to see what else GM comes up with.
