island, the question isn't one of whether or not Jeep owners DO use their vehicles off road. The question is whether or not they CAN. The Rubicon is named after the famous trail, which you can run with.........a bone stock Rubicon. I've seen several articles where they have done it, so it's not just clever marketing. I couldn't find any such information on the Cayenne after a quick Google search, maybe you can have better luck?

Belittle the hobby all you want, but some people really get into it. And for those that do it often, there's no arguments that solid axles and locking differentials are absolutely the way to go. Your understanding of articulation is flawed, because while you are correct about friction being a function of normal force you ignore one important point - you don't get any friction from one wheel spinning in the air. Look at the pictures of stogie's Jeep in extreme off camber situations, a Cayenne would be up on the high wheel on compressed suspension with the other side hanging in the breeze. You simply can't get the same amount of suspension droop and overall articulation with an independent suspension. There's a reason why every vehicle that is seriously built for this sort of work has solid axles front and rear.

Just be happy with what you have, because let's face facts - Cayenne owners spend way more time on the pavement than Jeep owners spend in the rocks.
