BMW's are well known for having speedos that read 5-10% faster than the car is actually going. The speedo may not be the best judge of actual speed.

this requires aftermarket ecu software (ie: dinan, powerchip, custom programming, etc).


Dealer most likely only has Dinan software available (other then stock)...

Why your car has the electronic limiter??

Mine doesn't has any speed limiter.

BTW, my 4.8is is euro spec and has 360HP instead regular U.S. spec with just 355HP!!

I have reached 262km/h in my car in a highway but I put VP race fuel uleaded on it :D :D

The 4.8is will be limited more by air resistance than any electronics but I would estimate that allowing for error it will manage 155mph quite comfortably.

I reached 160mph (indicated) in D by the way.

It's electronically limited..in US spec at least..

The actual HP is the same for Euro and US. Its just that your euro 360hp=US 355hp. :D The euro hp are small in size therefore it takes more of them to equate to 355 US hp :rofl:

Lucky guys.
X5 4.4i 2004 won't go any faster then a smidge over 130mph.

Wagner 08-21-2005 09:12 PM
with current gas prices...I'm not trying to bust any land speed records in a 2 ton plus SAV :)

Save that for the Z (160mph limiter by the way, but my ECU was reprogrammed in the Z) ;)

I do believe this is incorrect.

I was doing just over 235km/h (over 146 mph) on the PA turnpike 3 weeks ago behind an SVT mustang on my way to philly.

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

Very glad to see plenty of forum members trying out the full potential of their X's.

Need to try a bit harder than 220km/h it would seem.

Thanks for all the answers about sport and drive mode. Was very curious about why there is an RPM rise from D to S. Seems just like taking off 'Overdrive' on several older cars i've driven like the MGB GT.

My X5 went to about 132. The 330xi goes to about 140.
