I'm in the market for a new Aveo. Where did you get yours for $9200?
(You're right, your overall costs with a $9.2K purchase price will probably beat 100% of the hybrids which are all over priced.)

just filled up today. 80% highway/20 city. I got 35.78 mpg. I think that is very good. I've got 29k miles on my 07 (this was the wifes' aveo, family grew, I got her an 08 equinox) we love both vehicles. (for different reasons)

HELP..I got one of the 2009 Aveo5’s that gives only 18-22 mpg on average. Highway 24 mpg is a mechanical problem in my book for an Aveo. Chevrolet Customer service says my local garage has the technical ability to take care of it. My local garage seems to think I ride the brake, etc. It’s my fault. The computer says all is OK, according to them. A faulty part, wrong computer or program of something has to be wrong, but what. ?????

I have an 09 AVEO5 with A/T an measure 32.75MPG combined town/country in the hills of Virginia. No hwy/interstate driving.
Once I got 27mpg on a tank and decided it was bad gas. If you always use a discount gas, you might try a couple tanks of BP.
Some simple checks:
Check your oil - is it dirty. If so, change it and the filter and try Mobile 1 (Make sure you use the proper weight oil (5W-30 I think.
If you drive dirt roads - change the air filter.
Check your brake fluid - might be some trapped pressure that is causing your brakes to drag.
Feel the front wheels right after driving it - are they hot?
Is there grime on the front wheels (signs of excessive brake drag).
Lift up on the break peddle while driving on a level road and see if you feel the car gliding along any better.
The garage may be right about brake drag being your issue, but it might not be caused by a heavy brake foot. You'll have their opinion, now you need to figure it out yourself.
Hope this helps.

BRAKE DRAG AND mpg by norm116

Good suggestions, but have tried all of them. I had the garage check for emergency and wheel brake drag. Tried different gas stations, with and without ethel, etc. Reading the previous entries I have come to the conclusion that there is a small percentage that have the low mpg problem and GM hasn't addressed it. Take a look at #1 of 6 My 09 Aveo Nightmare.. Poor guy, I hope mine doesn't turn out that way..

My 06 Pontiac Wave (automatic) gives 15 kms per litre on the freeway. (roughly 35.5 mpg). 65-75 miles speed.
 
For mixed City-highway driving, I consistently get 11.5 kms per litre. (27 MPG). This is with thrifty use of the airconditioner. I use the heater almost all the time in the winter. I know that the mileage will fall when I do.

Of course it's no surprise that running the AC causes our mpg to drop. But i have found that on these little cars, it drops more than expected. You can really feel it when the compressor kicks in and with it running most of the time during the summer months, we get around from 2 to 4 less mpg. Overall though, even with the AC running, i still get the advertised mpg!

My 09 Aveo5 is Auto with Alum. wheels. Is it possible that my poor gas mileage could be do to larger dia. mounted tires giveing an adometer miss calculation. I read on an earlier posting that a TSB said odometer might be off 7 to 9%. Might the basic models have smaller diameter wheels and the computer is not set to compinsate. Is such info. out on 09's. This weekend I am going to check against the ionterstate mile posts. Norm
