I'm thinking it will have around 570 bhp as well. I think BMW will try extra hard to make it faster then the turbo s since it is the fastest SUV out there right now.

I hope its 575 bhp, that would truly make the ///M X5 a porsche hunter killer. Anyone else having a guess to what its going to be?

Bozz

Its 550bhp i have an conformation.
Somebody checked the source code of the X5M en X6M site and this is the result.

Great news ! I'm definitely in the market for this piece of machinery :)

Did you see post # 262 above and following posts?

OK, just to keep things interesting, I'm going to rain on the party, and guess 520 bhp:D. Sorry fellahs...

Also, I'm going to rain some more on the party and say it will be less horsepower than the new Cayenne Turbo S, and slightly slower to 60 mph. I'm going to say 0 to 60 in 4.9 seconds.

I think where it will kill the Cayenne Turbo S is in 1) lower price tag, 2) better looks and 3) equivalent handling and road grip. And those 3 will be good enough for me.

Keep in mind the torque on this beast starts with a 7. ;)

0-60 in 4.9 would make no sense. The X6 50i was clocked in Germany @ under 5 seconds...if this is to be the new frontier of ///M power, it will be impressing imo. Anyhoo, we'll find out soon enough :D

0-60 mph or 0-60 kph?

0-60mph is better than E92 M3, if that matters.
