I suppose that "batteries not charged" might affect mileage on a brand new hybrid, but the first tank is no time to judge the mileage performance of any vehicle.
 
There are a lot of things going on while a car "breaks in" including you getting used to driving a different vehicle. This applies whether we're talking about a hybrid or not, so give things some time to settle out.

The battery should only take a few minutes and few regen braking cycles to charge. So, I don't buy that.
 
It's most likely the break-in period of the car (as pf flyer suggests) and the break-in period of the driver. Getting over 40mpg out of this car requires adjusting your driving style. I'm getting about 50mpg on the last few tanks, but started in the mid 30s.

WOW 50 mph! I just purchased a NAH base but will not take delivery for 10 days due to the junker trade gov't program but I am wondering if you can give us some tips on how you do so well.

I currently own a 2007 Toyota Camry Hybrid and was very seriously thinking about buying new 2009 Nissan Altima Hybrid but I never pulled the trigger. The Nissan just didn't seem as "smooth" as the Toyota, although I think it drives better. I also had heard that the NAH did not quite equal the fuel economy of the TCH but I never heard it being as bad as you experienced.
 
General question, however, why did you decide to trade and (except for the fuel economy) do you have any regrets?

There's very little about the gas motor in a hybrid that's special. The only way to get better gas mileage in a hybrid is to KEEP THE GAS MOTOR OFF. If you aren't vigilant about this, then your mileage will dwindle downward to roughly that of a gas 2.5 Altima (if not a bit worse b/c of the extra weight from the batteries). There are lots of factors that can keep the gas motor on including anything other than the slowest/easiest accelleration, highway speeds, and cold weather.
 
I'm always amazed by people who buy hybrids without understanding the technology, simply expect the car to magically return better mileage, and then say the car's "defective" after it doesn't do what they want it to do.

Hi,
 
The reason that I traded in my Camry Hybrid for the Altima Hybrid was mainly (as a 6 year owner of a 6 cyl Altima Hybrid 3.5SE) I wanted to get back to the Altima feel on the road. I also assumed that I would get the 35 mpg in the city (I do a lot of city driving) that the Altima Hybrid was hyped to get compared to 33 mpg city for the Camry Hybrid. Well I am very sorry that I gave up the Camry Hybrid in terms of gas mileage. I had no trouble getting 33 city with the Camry and can't even get more than 29 mpg with the NAH. I tend to try to drive it the same way as I did the TCH like coasting whenever possible and not roaring off to a start and using the cruise control in the same manner as with the Camry Hybrid. But what worked for me for 11 months (and 11K miles) in the Camry Hybrid does not work for me with the Altima Hybrid. I have had the NAH for 6 months and 5k miles. I do like the ride and the pep but could have gotten that with the 2.5S Altima for a lot less $$$ and nearly as good mileage!

Cruise control by cephraim

Cruise control on the highway is good, but not great.
 
For better fuel efficiency, you're better off driving with constant throttle vs. constant speed, kinda like the truck drivers do. Faster downhill and slower uphill.
 
This is called "driving with load (DWL)", one of many "hypermiling" techniques.
 
Check out cleanmpg.com for more ideas, if you are interested.

44mpg in the summer.

Very interesting. Most of the time, I drive in the city and I estimate I get about 31 mpg in the city. That's not bad considering I used to have a 2002 Corolla and I only got 22 MPG in the city. A 2.5 S will likely get the same mileage as the Corolla in SF city driving, and be down about 20 plus HP compared to the NAH. The CVT transmission in the NAH is better than the NA 2.5S so be glad you don't that transmission.
 
Sorry to hear your NAH is not working out to your expectations. So far, it's working out well for me.

Glad that you are having a good experience with your NAH. In Maryland only a couple of dealers import one or 2 Hybrid Altimas (probably from New Jersey which is the nearest state selling them). Mainly they seem to import the top end model (leather bluetooth navigation system, spoiler , sat radio, etc) I should have gone up to NJ myself so that I could have gotten a lower end NAH. I must admit though, I love the rear Camera! I now only back into places and it makes parallel parking as easy as pie. But anyway, a lower end (with a price about 5K or so lower would have lowered the sting of paying so much for crummy mileage (compared to Camry Hybrid). I guess I either have a dud or I need to drive the NAH differently than I drove the Camry Hybrid to get better mileage. I will be experimenting some more I guess!
