Altima Hybrid Mileage by wayne8888

Hi All,
I have been waiting for summer to improve my 2008 Altima Hybrid's mileage. I bought it brand new in January 2009 in MD where they seem to import them from New Jersey to sell onesey twosey in this non Altima Hybrid State. I traded in a 2008 Camry Hybrid fo get it. The Camry was giving me about 33 mpg city and 40-44 mpg highway. Unfortunately with the Altima Hybrid, I am only getting 27-29 mpg in the city (and this is with the optimistic computer) and low 30's on the highway (so the city mileage is what is the huge disappointment to me .....even in July). I have nearly 5000 miles on my Altima hybrid and drove 11K miles on the Camry Hybrid. I love the Altima but it does not touch my former Camry Hybrid in mileage. It might be the luck of the draw with the Altima Hybrid with some individual vehicles beating the average but also with others falling far short of the average.
       Has anyone noticed any differences in mileage with different brands of gasoline? Thanks!

30 mpg for the first tank by xav

30 mpg for the first tank (that I manually measured). About 50-50 city/highway. We also use the A/C all the time and I played with the acceleration a little.
 
The dealership told us not to expect to get good success with the first tank, given that the hybrid system batteries are not charged yet.
 
What do you guys think?

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?

Hybrid mileage note by roar02ram

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.
