The term Cardan is in reference to a u-joint or double u-joint style shaft you would see under older 70's GM car and some newer Trucks. The Stock shaft has a rubber Guibo at the front, then the hanger and after that is has 2 CV's like the ones were using on each end. This pretty much removing the "problem" parts and making a single shaft.
Why is this not compatible with the V-6?

Think they'll hold 700 WHP? The owners of my 5.3TT engines keep asking about something like this? I'd considered developing it from scratch, but have no desire to work with drivetrain products.

Funny, I was asking about this a month or so ago. The people I contacted were too worried about vibration issues on such a 'long' driveshaft...which sounded like horse-apples to me.
Glad you're selling these. I'll probably pick one up soon.

Are those bored out cayenne engines?
Its "bored out" among other things to include billet rods, LN Nickies cylinders, JE forge pistons and our CNC cylinder heads.
With this, you need all the driveshaft that you can get, and some good tires, too :-)

I'm still waiting to hear why it won't work in a V-6.

I'm curious about them too.
Why would Porsche add complexity and expense to a driveshaft? There must be some benefit that they see value in! What is it?
Seems that stock shafts last anywhere from 70-140k miles and have been "revised" several times, yet Porsche themselves never simplified the design like this. Must be a reason!
In theory the new factory revised shaft would last even longer than the shaft you are pulling out to replace. Which is longer than many of us will own the car.
A rebuilt one can be purchased for about $400 and other "permanent fixes"(yet to be seen if these stand up to their hype too) can be had for about the same.
So what are the advantages/disadvantages of these shafts that are 2x-3x the price of the other solutions?
One perceived advantage of "better throttle response" has already been mentioned. Others?

Perhaps the oe design takes a little stress off the system. With the flex disk absorbing the initial burst of twist. I wonder if the driveshaft is almost designed as a consumable to make the rear diff last longer. I am pretty much just speculating though because I have no effing idea.
