2009 X5 V6 Low Power?
The X5 did not jump off from stop. I didn't floor it, just a gentle push that on my 528 just causes it to go thru the gears nonchalantly. What truly disappointed me was the way it behaved going up a steep paved hill. From a full stop, it thought it was just fine lugging the engine creeping up the hill in 4th or 5th gear (couldn't tell). I finally had to blip the gas pedal to get it to downshift with quite an uncomfortable lurch.
I just drove my 528 up the same hill from a full stop. It clearly started up in 1st gear, went to 2nd, eventually to 3rd where it stayed until the hill got a bit less steep. Good performance and well engineered decisions on when to shift and to what gear.
Was something screwed up in the test X5's transmission or adaptive logic? I told the salesman the performance was inadequate, but he didn't seem to react and remained non-commital.
I tried to research this question on this and other groups, but nothing precisely hit it. If this is a dupe, pls excuse. Thanks in advance for any responses.
