There are two issues I seem to encounter:
1. Very slow throttle response until pedal is pushed in about halfway, then pretty aggressive pulling. This seems mitigated by just using more throttle early in an acceleration. 2. Most of my issues are confined to the car's behavior with a cold motor. There is a very definite sine wave of revving that occurs with the A/C on (maybe with it off too but I've never done that...). When idling forward today after the motor had been driven for about five minutes (eng temp gauge was about halfway to 250) it was pretty obvious to me the car was lurching into the parking spot (not smoothly and brakes had to compensate for higher revs to creep forward linearly). The bizarre thing is this doesn't happen all the time - seems to be about 10-20% of the time but it is pretty obvious in a parking lot, let me tell you! All in all, it's still a great car and I have little doubt at some point BMW will reflash something to alleviate similar concerns. I have 2700 miles on mine.

I think the car just takes some getting used to.
As I said earlier, I don’t have any of those problems on my 28i-non-sport. If I want to accelerate slowly in traffic, I just press a little on the gas and hold it there, if I want a more aggressive start I press harder and hold it there. What I DON’T do is start with easy pressure on the gas and start moving my foot around. This can confuse the car as to what you are asking it to do. A steady pressure on the gas pedal is key. |

Ok thanks guys..seems like the key is to hold the pressure.

If you are an aggressive driver you will notice it. Of course if you are driving the kids to school, or are not hard on the pedal, then you obviously won't.
I'm at about 3000kms right now on an X35i. The 'lag' is still there. It is very noticeable. If I'm in the slow lane in traffic and want to pass, I have to switch into Sport mode to make sure I get the right acceleration to merge into the other lane. It's very annoying, but it's not a deal breaker for me on the vehicle. I don't often need a faster response, although sometimes I wish I didn't have to switch it into DS just to eliminate that. I even called my dealer, he said I wasn't the first person to comment on it, he's had a few, and the only thing he can tell his customers is to go into DS mode. My friends have driven my car and get the exact same results as me, but from everything I've read it's normal and it's because of the turbo and for fuel 'efficiency'. So, maybe we'll have to pay for a third party flash to eliminate this down the road. |

It sure would be nice if BMW offered a manual trans or dual clutch trans in this new version of the X3 here in the US. Then some of us could choose to avoid this issue.

Want the thrill, that's precisely the issue I have randomly! For the other folks, the throttle issue I have has nothing to do with rapid accel - when you mash the pedal it goes - and goes smartly. Crawl speed the throttle response just doesn't seem linear - a tough car to drive at 1/4 to 1/2 throttle...

if you have problems in park, that seems like an entirely different problem
i agree the initial throttle is difficult to modulate smoothly. it's okay if you're slow between releasing the brake and applying throttle, but who has that kind of patience? Quote:

Just hoping they smooth out the pedal with software..

Hmmm, good call, my issues are confined to when it's in Drive, generally. In park when cold sometimes it seems to rev high but nothing too crazy. The rev interval seems to be a peak and valley every second or so with a difference of only a few hundred RPM. I'm in the middle of a move right now, when I get to Wa DC we'll have the Bimmer folks take a peak. I'm hoping it fixes itself...

It's still a fantastic drivetrain. I think it's worth a little discomfort. Think about the first time you drove run-flat tires. How annoying was the harsh ride? And if you're still happily driving a BMW, you probably got used to it. |

FOR MONTHS AND BMW HAD NO ANSWER FOR ME. I'm waiting on my replacement for my "lemoned" X3, so hopefully things will go smoothly the second time around. |

SOLUTION
I've found that using manual mode and shifting into second before taking off from the crosswalk smooths out power delivery. Then I just push the shift lever back into full auto when I've gotten going.
Try it. It's really very nice. It's almost as linear and smooth as a naturally aspirated, torquey V-8, and it makes quite the sonorous, throaty, growl. |

I just did the BMW Drive for Team USA today so I drove another X3. I guess if you know how the throttle works on the car you don't notice the acceleration delay anymore. I'm glad.
