Top Speed Question..
I was just sitting here thinking about the ESS tune on my M and have a question.. I know that the top speed is normally limited at 155 mph. When the limit is removed, how fast will a stock Z4 M go? Believe me when I tell you, I have no place here to verify this... but I was just wondering if anyone has found out?? Thanks Chuck I

When it warms up I'll let you know. Maybe even this weekend as I'm headed to Frankfurt and it should be over 50F. There are a few good unlimited sections on the way. My guess is it'll do 170 in 5th gear.

on hamman's website, with the software and the top speed removed they say it can do 273 km/h= 170 mph. 170 in 5th gear is stretching it, i think.

Remember, the spedometer gets more off as speed increases, so unless you're being checked by GPS/radar/lidar, you were most likely in the low 160s if not high 150s....

Yes I know, I just wondered if all Z4M's showed 170 or if they stopped at 155mph as they are supposed to

I've tested this many times before and my max speed is 275km/hr (170mph).
This was verified by onboard computer, and my car is stock. Had been maintaining the top speed of 275 for well over a minute as well. Car refused to go any faster too. BTW - in your manual, you should see there's actually a "M Driver's Package" which apparantly ups your top speed from 250km/h to 275km/h. My car is Asia spec. |
