X5 4.8 top speed
 

Been on some long drives recently and had to 4.8 up to 220km/h, but have a couple of questions about the top speed.

Is the car limited at all?

Can you go as quickly in Sports mode as in Drive? Once sport mode is engaged the RPM's rise and the shift mode changes, but will it allow you to go as quickly with this different ratio in sixth?

Might have to go and try it i guess, but would just like to know.

Sports mode is where the car will give you maximum performance.Sports(manual) mode will enable you to change gears at higher RPM and thus also achieving max.speed.(about 265 kph on speedo,which is 250+ true speed.
What rpm were you doing @220 kph?

I read somewhere that the top speed on X5 4.8 is 153 mph.

I put sport (manual) mode in my 4.8is and I can't raise more than 6500 - 6700 rpm in any gear...

What should happening in my case?

Thanks!!

4.4 230km/h
 

I clocked 230km/h. 5th gear gave 6000rpms then changed to 6th and the revs dropped to 4500. There was still more umph but didn't have enough road :mad:

Manual claims top speed at 240km/h, in my case (2005 4.4) I would expect some electronical limiter, cause I am sure I'd pass 240!
You guys with the 4.8's - Respect :thumbup:

I actually filmed doing 220km/h on my phone but somehow can't transfer it to my computer. Maybe someone could help out. My mobile phone is the Samsung SGH-D500E. It's actually a nice piece of film done on the Italian highway to Venice.

Does your phone have a hardwire USB connection to the computer? If so, you can open the phone as a device under "My computer" and then copy the files over. That's what I do with my Audiovox SMT5600.

It's limited to 153mph. Given the drag that car puts out I don't think it would ever see the end of the speedometer. Not to mention the fact that the majority of speedometers become inaccurate over certain speeds....of course..when the cop clocks you at 176mph then you can tell everyone you hit it...from jail of course :)


153mph per BMW

sport mode is only a throttle map change. it uses a more aggressive air/fuel map for the given variables (throttle position, change in accelerator pedal, temp, etc) it does not raise the rpm limiter.

the car is electronically limited to 153mph, as said by others. gears are mechanical and fixed. they do not change ratios unless you put different gears in (change of transmission gears or differential gears).

I've seen just a click under 160mph on my speedometer in my X5 4.8is which I did a few weeks ago on a quiet Autoroute. I was following a Ferrari 355GTS at the time.. :D I've not felt any limiter kick in so I would suspect it will be like on the M3/M5 where it only intervenes at around 167mph. 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.

is there anyway to take the electronic limiter off? can you ask the dealer to?
