 06 525i vs 06 530i, could'nt feel the diff



So I drove an 06 525i auto sport and 06 530i auto sport back to back. Frankly, I could not really feel the extra 40 hp the 06 530i has on the 06 525i. The 525i seemed to have more than adequate power for day to day driving, and pleasently surprised me, as the thought the 530i would feel substantially faster. However, the 530i did seem to have slightly better handling, maybe due to the 18" wheels. Anyone else have similiar impressions?

thanks

Try 545. You'll feel the difference. All sixes are similarly underpowered.

Where on the RPM curve does the extra hp appear and where in the RPM curve were you driving it? I'd expect you to notice the torque more than the hp unless you really drove the heck out of them.

So by that analogy, the 545i and 550i cars won't feel that much different either!



Seriously, you should be able to notice 30-40 hp or whatever the torque difference is...you really should.

You might not "feel" it but the stopwatch definitely will!

If I remember correctly BMW estimated 0-60 mph for the original 745i to be 5.9 sec. Same source now gives 750i slightly better 0-60 time of 5.8. May not be noticable. Note also that the new 750/550 engine has larger (+0.4 liter) displacement. 525 and 530 are both 3 liter engines.
