My Ride: carbon black/black dakota, M package with M aero kit, M suspension and 18" 135 M style wheels - steptronic, adaptive bi-xenon, active steering, moonroof, comfort seats, comfort access, nav pro, logic7, CD, HUD, PDC and some ...

Saturday I drove on an empty German Autobahn (probably due to the soccer World Cup) and did a little Vmax racing with a Suzuki Hayabusa (I didn?t have the slightest chance BTW). The HUD showed a top speed of 262 km/h in M6 before I noticed the rev/speed limiter kicking in at about 6100 rpm.

Now I wonder: did BMW set the limiter wrong (normally it should kick in at 250 km/h) or doesn?t the HUD show exact speed?
Any opinions on this?

The speed gets off as your speed goes up in Bimmers. Its probably pretty close to 250...

Lucky you, maybe.

But, you could always use the hidden "true" speedo and tach to check your results--assuming you can get to it in your German model. Check out post #28 of this thread. The post shows the procedure I developed/used intitially. It seems complicated, but really isn't. Now, I can access the hidden speedo and tach, etc., just by sort of bumbling through.
