Hi,

I have a 2012 X1 28i with 8 speed auto. I have had it for quite a while now. Although I love the low end torque in this car, but this is what I have noticed from a stoplight. I accelerate pretty slow-moderately from a traffic light usually around 2000-2500 rpm. What I noticed is that the cars next to me usually beat me in terms of acceleration even the bus. I mean if I'm accelerating the car at 2500rpm, then they gotta be accelerating the car 3000rpm and up. Is this because of the 8 speed auto? It seems to shift upwards really fast from 0-60km/h (0-40miles/hr), probably shifted twice or 3 times maybe even 4 times, so most of the time during acceleration is lost from shifting into a higher gear? It's a 6.7 second car, it's got the low end grunt from 1500rpm, but it doesn't seem to pull very well from a dead stop? I know I'm contradicting myself here but this is what I feel.

I also have a 2005 chevrolet cavalier, the car seem to accelerate faster from 2500-3000rpm from a dead stop than the x1.

I'm not a pro car guy, am I losing optimal power band from certain rpm ranges since it's a turbo? Or is this an issue with both the turbo and transmission. Please let me know.

Thanks.
