It had more but I got tired of my wife beating my arm. :rolleyes:

She still had a huge smile on her face after the run!! :D

Then I am confused.
Is it because I am aerodynamically limited?
I do not have the Sport Package, could that be the reason?

Were you slipstreaming? Possibly that is the case?

BMW installed a 130mph limiter on the latest model years :mad: - maybe the chip - it disappears with a Dinan upgrade :thumbup: - Hyjk "you're a better man than I", too many people on that road :rolleyes: - out here you can see stretches of interstate for more than 10 miles and count less than 10 vehicles on all 4 lanes. :wow: Had to laugh at your wife's reaction(both) :rofl: :bustingup :rofl:

Do you guys feel safe in the X at 150 mph??? I was pushing my 4.8 to around 135 and it didn't feel that safe to me...but then it could also be the fact that I was used to my M3...dunno...

I didn't realize that tapping the shifter into the 'sport' mode changed anything other than the shift points! If it actually remaps the throttle, etc. (as in the M3) then that's absolutely fantastic!! :thumbup:
I've always driven in sport mode anyway, so I never really did much of a comparison...

I felt like a rock @ 130mph. I was kinda ticked off I couldn't go faster.
Same feeling in a R230 (SL Mercedes).
Not the same thing in a LS430. The LS430 is scary because it still seems like you're going 80mph. Just a whistle.. it's a weird feeling in that car.

I did 160mph (showed in speedo) in my 4.8is and I felt the car stable as my SL55 AMG.

The air suspension is just incredible in this car!!

i rocked my 3.0i at 121 mph the other day. i want it to go faster though. i need to know how!

I went a little over 130mph with an 04' 4.4 X5 on my speedometer last night on the 405S. :thumbup: Yeah it was rock solid, and I was pretty confident enough with it. 110 mph cruising limit speed would be great :) I don't know why you would feel less confident on a 4.8 IS. At 130mph+ the X felt that it had more punch to it, but I never had enough road and the safe opportunity to max out the full potential of the engine.

BTW, maxed out a 2000 4.4 eurospec x5 at 220 Kmh. It should be better for the newer 4.4 engines.
