The porsche's handing is a little more sophisticated because all it has made up to this point is sports cars that focus on turning and handiling. They both have smooth rides as you could presume. The turbo is extremely fast and rivals almost every sports car ( M3, Boxster, Audi S4). So purley power trubo wins. As for hangling they are about the same maybe a slight edge to the cayenne turbo. Both interior's are phenominal, as all porsche's and bmw's are.--- Eaither one chosen is great---These are the fastest two SUV's made porsche being that fastest.
I guess I should reply to this as it's usually my replies that get the folks on Roadfly so worked up . Some of the Cayenne owners are so religious about their cars that they cannot bear to see it criticised..

Anyway, I disagree with some of the points above. I've driven the Cayenne TT many, many times in my search for the ideal SUV and I'm a long-time Porsche fan who has owned Porsche's and BMWs together for the past 15 years or so. I fell out of love with Porsche over the 996 (of which I owned three) and I've since been looking for a reason to buy another Porsche since I'm still an owners club member and miss feeling part of the family. I've now decided to order an 997 GT3 so will use that for my Porsche fix but I just want to set the scene that I "really, really" wanted to like the Cayenne. I have owned 12 Porsches and so often heard the 'blind' faith that since Porsche have a heritage of building sports cars therefore they must by default be the best 'drivers' cars. They're not I'm dissapointed to say, they make as many mistakes as BMW but there are still some gems in their lineup.

The biggest failings for me with the Cayenne were that it didn't feel very sporty, didn't sound sporty and didn't steer like a sporting car either. It felt like an 'Audi' to me, sharp suit, clinical but little emotion. Compared to my 4.6is X5 at the time it was like a choir boy rather than a football player. The Cayenne's steering was light and completely lacking in feel and the chassis whilst much more competent than the 4.6is needed personality. This was the same problem I discovered when I first moved from a 993 to a 996, the 996 was dynamically better but lacking in soul. I've since bought a 4.8is and this has levelled the playing field with the Cayenne TT, being much better chassis wise than the 4.6is and feeling just as smooth as the Cayenne but more of a drivers car also.

The gearbox on the TT was much better than my old 4.6is but now with the 6-speed unit in the 4.8is BMW has turned the tables again and the whole gearbox/engine match is more succesful than in the Cayenne. Very smooth, responsive and in the 4.8is the manual mode is one of the best I've ever driven in an auto box - it's a bit like setting 2 or 3 in the SMG gearbox in my M3 CSL.

There's just no comparison in noise between 4.8is and TT, Porsche should be ashamed of themselves being so totally overshadowed by BMW when in comes down to exhaust tuning. Again the TT lacks character in comparison.

Performance wise, I was always disappointed that Porsche built an SUV that weighed 'more' than the X5 (300kg more) and you can feel this every time you swap between the two. Off the line, the 4.8is is much quicker unless you are brutal with the TT, but even then the 4.8is will initially pull away by a few cars. I've found that in head-to-head comparisons on the road that the 4.8is pulls away then the TT pulls it back and by 100mph is a few cars ahead. Not much though. The TT has a power/weight ratio of arouhd 190 bhp/tonne whereas the 4.8is is around 175 bhp/tonne but in terms of responsivness and drivability they're matched and it would take a very long road for the TT to pull away significantly, which it will eventually. But neither of these are 'performance cars' in the traditional sense, they exist as much for the experience of driving them and in that regard the 4.8is majors on exhaust noise, responsive and smooth engine and fluid chassis. The TT majors on it's explosive mid-range turbo power, more contemporary interior and decent handling. I'm sure you could enjoy either car, but if you're used to the more sporting style of the X5 then the Cayenne can seem a little lacking.
