You can experience this motor today at a local BMW dealer here in the US - just test drive a 2012 528i. I had one as a loaner which is what my feedback is based on. I believe the base Z4 also has this motor.
The 528 weighs 400lbs more then a 328...test a z4 i you want a real comparison...the 328 is very similar weight to a z4.
