First stop in Ohio and I'm getting over 36 miles to gallon... The computer tells me I have over 440 mile range after filling up.

Second stop and still registering 36 mpg

If you have a chance and the inclination, check it with pen and paper as well. My Cruze had an optimistic DIC.

is there a battery warranty or is it under powertrain, i don't want to be the downer here but how long are the batteries supposed to last?

what is your average speed? 36.1 mpg= nice.....

Sounds great! As long as there aren't reliability/longevity issues, this should be a great product!

Apparently the gear ratios, or rather, final drive ratio, are tuned for fuel economy rather than acceleration. The addition of eAssist allowed GM to keep the RPMs lower than before while still allowing for adequate acceleration.

Sounds like the electric assist more than made up for the reduced engine power to the wheels... nice. How often does it downshift on the highway? eAssist is supposed to reduce the need for that as well.

Is their a noticeable fan noise like some critics have said?

28.9 on the first 1/2 tank (pen and paper) the first 1/2 of that was my city/suburban cycle

I didn't look on the DIC, but I did 65 - 70 most of the way.

under steady cruise, only under a steep hill, but it will downshift twice when it does.

I didn't know anyone had reported that. I've noticed no fan noise. It's as quiet as a Buick

Not a car for my taste. But a big car with great fuel economy, smooth ride and semi-taut suspension - it would be a perfect car for eating miles.

one website review mentioned it sounded like a vaccum under hard acceleration due to the fan at the back pumping air into the battery

Yes I read about the fan noise in the Malibu Eco too, but it was audible to rear seat passengers only. Those passengers likened it to an airplane taking off.

To think of it they might have been talking about the Malibu, is the fan always on Ocnblu?

I haven't heard anything like that at all.

Well good to hear that Olds, they must have made strides to keep it extra quiet in the buick

The Lacrosse goes back to GM in about 2 hours... and I'm really sad to see it go. I filled up the car the night before I left Detroit. A full tank gets you over 500 mile crusing range but I was a bit more hurried coming home and averaged 33mpg which cut the range back a bit.

Power is softer than one might hope under hard acceleration, but in normal situations, it still rolls with a V6-like feel.

The car that GM will be dropping off to replace it will be good for the Nor'easter that is predicted to hit here in the next 24 hours. Any guesses as to what it is?

You're not getting a Nor'easter. You might have a blizzard coming, but not a Nor'easter... a Nor'easter is like a weak winter hurricane... where the center of the storm is mostly over the ocean, and it heads northeast with the gulf stream. You're too far inland to get much Nor'easter weather.

You scared me, though... I had to drop my lunch and pull up the weather.

We've had 'em

But, what did i get for it?

After the contacts I made in NAIAS this year, you guys aren't going to have such easy guesses soon ;-)

Is it by any chance a GMC Terrain?

overall, did you pretty much get around 30 mpg?

It was pretty much what the sticker says. Highway cruising (at legal speeds) got me 36 mpg. City I got 27.6mpg. Blend that to suit your driving.
