No dude I said nothing of a twin turbo...I'm a wee bit smarter than that...Hell I own a bimmer don't I.

I have a 05 RR sport diesel for the last 2 years with not a single problem and found it to be great off road, the air suspension was great for carrying heavy loads and you can tow what ever you like, also have a 2001 4.4i sport and you can't compair the 2 on the road. The X5 is much better on the road and performace is in a different league just depends what you want to use it for.

I don't really see much point on having a RR SC as it just doesn't perform well on the road and if you want it for towing and off road work get the RR diesel

I've driven a Cayenne Turbo, and I would have to agree that - because of the turbo - it is quicker than any stock X5. However, I added the Dinan S3 package (which includes supercharger) to my 2003 4.6is (see http://www.xoutpost.com/x5-e53-forum/...an-s3-wow.html ), and have clocked myself 0-60 in 5.2 seconds, which I believe is faster than any stock SUV except the Cayenne Turbo S. Range Rovers aren't even in the competition at that level.

Well not anymore...the SRT8 Jeep does it in the high 4 second range (about 475 HP), the ML63 does pretty close to 5 flat I believe (507 HP)

I guess that's right...somebody's always coming out with something bigger/faster, aren't they!? :confused:

Somebody who's a better driver than me (and used an optimal "launch" procedure) might be able to get my S3 4.6is down to 5 flat, but I doubt it would ever break into the 4's!

I guess if I want to go faster than that, I just need to park the X5 and take my M5 instead - I believe its 0-60 time is 4.1 :rofl: ...but that's a whole 'nother topic... ;)

There are few threads in this forum on Cayenne turbo vs. X5 4.8is discussion if you want to check out.

I've got a problem excepting that SRT 8 does it in high 4r's. Has anyone driven one of them? I mean really driven one? I had one for the weekend, (was thinking of getting rid of the X, thank God I didn't). First of all, handling SUCKS! There is a terrible hesitation when you punch it. It's like your hauling a house when you gun it to take off. It takes forever. IMO, I don't see the 4 second thing or high 4r's for that matter. I'd say maybe high 5's but nothing that fast. I never timed it and don't want to. The handling and drive alone will not sell me at all. MB, don't know about that one. But I'm sure since its AMG, that the handling is superb and acceleration has to be top notch. But again, as for Jeep SRT8, Great idea, but that's where it ends, at the drawing table. Again, my opinion only, so any Jeep fans out there, sorry. But the SRT8 is not what you think it is, even with that huge engine.

well you can't expect that much out of a car that is supposed to compete with 100k+ cars for 50k
