i agree with this...my mileage has gotten 1-2 mpg more after a couple of thousand miles
Well I got 30.5 for the first tank, Not very impressive. About 1/2 way thru on the second and at 31.5 better but not a winner yet.
AND TODAY !! Ta TA finished the second tank for an overall tank mileage of 34.5 Drum roll please. Hey this baby is gona be a winner.:)
I am at 9500 miles and it is getting 37.1 mpg. Mostly highway keeping to 65 as best as possible. Quite happy with that!!!
Just bought my Altima Hybrid 2 weeks ago. One long trip about 400 miles and the rest local errands. With the long trip and 1 week of local travel the gauge indicates 38.3 MPG. Driving mainly with cruise on at speed limit.
I'm keeping running data at my blog. Please feel free to comment. Also posted picture of the instrument cluster.
The saleman told me that it takes about a month for the Altima Hybrid to learn how I drive before it would get the best fuel economy.
I've read quite a bit about the NAH hybrid system and I've never run across any mention of an adaptive system based on driver input. I know some cars with adaptive systems adjust shift points based on how you drive over time but the NAH has the Toyota power split device which doesn't have shift points. I believe that the NAH system always tries to maximize economy and it's more or less up to you to adapt to get the most from the system.
One way to boost fuel economy is to shut off the climate control when you slow down/stop (whenever you would normally expect to go into EV mode) when you are running the heat AND the engine is not fully warmed up (1st ~10 mins. of driving). If the engine is cold and the climate control is struggling to bring the cabin up to the set temp., the engine will not shut down, even if you are stopped dead, because it is trying to make you comfy. Stay cold and save fuel! Just remember to turn the climate control back on when you start up again to warm your tootsires!
