langie, read post #145, and you'll find the op stated the only way for a NAH to save gas is to put it in neutral when going down hills. Reltated that to my statement of going downhill.
And I agree with your statement about highway mileage. I would add that the NAH will likely outpower the 2.5 quite easily on the highway and use the same amount of gas. The NAH is quieter than the 2.5 on the highway because the electric motor assists it on the highway.
#150 of 158 NH Winter MPG for NAH
Feb 06, 2010 (3:22 pm)
New 2009 NAH bought in Nov. 2009 (under $19k with Nissan rebate, dealer discount and tax rebate). Bought it just as it was getting cold. Definitely not in the same league as the 2001 Honda Civic I was driving. MPG definitely drops in big-time in cold weather. In below-freezing weather the NAH takes about 20 minutes to get warm enough for the hybrid EV system to activate. Also, the car's mileage computer gives inaccurate average MPG readings -- about 10% (or 2 MPG) higher than reality.
Actual mileage records (300 - 450 miles per fill-up):
About 50% urban/surburban and 50% highway, trip computer ave. speed 25-35 mph
12/15/09 Car computer: 29.1 MPG // Actual: 26.8 MPG // Conditions: 15 - 40 degrees F and some snow
12/23/09 Car computer: 27.9 MPG // Actual: 25.7 MPG // Conditions: 5 - 35F and some snow
1/10/10 Car computer: 29.4 MPG // Actual: 26.8 MPG // Conditions: 10 - 45F and some snow
1/21/10 Car computer: 31.7 MPG // Actual: 30.0 MPG // Conditions: 10 - 40F and mostly dry, more highway miles
1/31/10 Car computer: 29.4 MPG // Actual: 27.4 MPG // Conditions: 5 - 30F and mostly dry.
Hybrid system works fine -- up to 40 mph *if* the car is warmed up. I'll post more records as the weather warms up. My guess is that the Altima 2.5 would be a bit worse than this because of the winter penalty, but not a whole lot worse.

newhampster - welcome to the forum and the NAH.
Read my post #134 for some more details on how to improve your mpg.
My worst tanks in Rochester, NY (where we are at 12degs today) are in the 32-34mpg range, but I get up in the 44-47mpg range in the summer.
Granted, I'm a major hypermiler. But, it can be done.

First note- Im not a hypermiler and we moved from CA with our '08 NAH to Minnesota. I drive to 35 miles to work everyday which is about 40% street/60% highway. We've had a very cold winter down to -10 and Ill get about 30 mpg at the lowest (check at fill up not what computer shows which generally is 2-3 higher than actual.)
Also on warming up, it takes about 5 mins of driving on the freeway to have the light turn off. In the summer Ill get my standard 36-38+mpg on the same commute. Overall very happy with the NAH and after 2 years and 15k miles, we've had zero problems which is good cuz MN is not a state where nissan dealers know much about this car.
My wife also drives a '09 Tahoe hybrid which also drops down in mileage during the winter. No biggie

Radiator blocks and engine block heaters help with the warm-up period...
#154 of 158 Coasting in neutral
Feb 09, 2010 (10:25 am)
To improve mpg w/ the NAH, I sometimes shift into neutral downhills to coast further . But, when I shift back into 'D' to continue on, I have to wonder if I'm doing damage of any kind to the CVT. Is this a legit concern?
Feb 09, 2010 (12:00 pm)
I often shift into neutral while in EV mode at the top of a hill.
This allows you to coast up to speeds above 41mph in EV mode.
I shift back into gear from neutral regularly in EV mode and gas mode.
The only thing I would avoid is a shift from a highspeed (above 50mph) EV coast back into gear, as this seems to rev the engine a lot.
But, on the highway, I pulse and glide in and out of neutral without problems.
The CVT seems perfectly designed for this move. Worst case, I get it covered under the new 100K warranty!
Jun 03, 2010 (6:51 pm)
I get 32-33 on highway -90% highway and 10% city. Over all Car computer tells 31.5 over 12 k miles. In city I get between 30-32 with stop and go traffic. On a single tank 550-610 miles. In winter 29-31 over all. Best ever was 34 during a long trip.

This board has gone quiet. I just bought a 2011 NAH - loaded. I'm abut to take delivery and feeling nervous reading these posts. Any updates? Are you enjoying your NAHs? Are you averaging low 30s for MPG?
Jan 29, 2011 (4:05 pm)
The dealer says it's time to change the engine air filter (not the cabin air filter) in my NAH. I know this is something I can do myself but the pictures in the manuals leave a lot to be desired. I looked online for videos, but found none that showed me how to find the air filter cover on my NAH. Can anyone navigate this for me, or post a photo? Thanks.
