Bmw's don't high idle on cold starts?

So, I've wondered this for a long time..

How come my 2003 bmw 330i doesn't high idle on cold starts and gradually reach idle speed as it warms up?

When i had my g35, on cold starts it would start off at 1800 rpms and slowly move down to idle until it warms up completely. bmw doesn't do that.

It seems as if the engine reaches idle speed way before it completely warms up.

Is this an emmissions thing and common with all bmw's or is there something wrong with mine?
