Driver adaptive transmission. Question
 

***SORRY I POSTED IN THE WRONG SECTION. I HAVE REPOSED IN THE E53 FORUM.****


I am very lucky. I happen to have two 2005 4.4 sport. So as fare as I can tell they are mechanically identical, They even have identical wheels and tires.

I got these used. I got about 7K miles on one and about 3k on another. I notice on one of them that it drives and shift a lot sporty, it is more responsive, shifts more crisps, gas pedal more sensitive. For example on one of them in a dead stop I press the pedal look down and the mpg gauge automatically goes to 8mpg but the other I have to make a little effort to press the pedal more to get it to 8mpg. The other one drives smoother.

Now I don't want to think there is something wrong with one of the X5. They both have low mileage. And I don't have any indication that anything is wrong except for what I have describe here.

They only thing I can think of is the adaptive Is there any other explanation for what I am describing.

BTW I don't have an aggressive driving style at all. I am use to driving big SUV and you folks probably would describe me as driving the bimmer like a big SUV truck.
