My 2010 Transsyberia is in for service to address some issues, and I'm driving a 2010 6cyl Cayenne with standard (non-air) suspension as a Service Loaner.

1.) While the drive train in this 6 cylinder TipTronic loaner does not have the giddayup and go of the GTS TipTronic in the Transsy, it is far smoother shifting through the gears when accelerating. The Transsy has harder shift points and seems to stumble or judder under mild acceleration, especially in 4th gear. This loaner does this not at all.

2.) The Service Loaner also seems to be smoother when going over RR tracks and speed bumps, in spite of my having the Transsy's air suspension set to "Comfort".

3.) The Service Loaner also probably has standard seating, as opposed to the sports seats of the Transsy; and it feels like there is a smidgen more room in the loaner. Related is the fact that after only 750 miles on the Transsy, the Alcantara seating surface of the driver's seat already has permanent creases.

4,) The standard leather wrapped steering wheel on the Loaner has a much better feel and grip than the Alcantara wrapped wheel on the Transsy.

Just some comparative observations.

 

my gts alcantera seats are still in great shape after 16 months - strange

the sport seats are much tighter than stock.

 

What size wheels on loaner and yours?

 

255/55-18 on both. Goodyear Eagle tires on the Transsy and Continentals on the loaner.

 

Tire choice on the TS is an issue but I too have driven a new V6 Cayenne (looking at the Panamera - don't ask). My TS is every bit as smooth as the base in comfort mode. Also of note my air compressor is silent and the vehicle adjusts height except when asked to. In fact, my TS felt smoother shifting than the base and it was really smooth. The vehicle that I was looking at trading in on another Cayenne was a ML 350 and the tranny on that was positively rough compared to either Porsche. I really think something is not right with this TS.

 

Dealer did a recalibration of the air suspension yesterday and thought it was OK. He checked it this AM, and it still is leaking. They now think it's the compressor check valve that is supposed to hold the pressure. They have to order it in for installation tomorrow.

I hope they're not just throwing parts at it.

 

That would explain the ride and the compressor being on and the ride height adjustments. Boy, I hope this gets straightened out for you as the vehicle is just amazing when it is set up and working right. Smooth and capable. Everything is almost effortless. My fingers are crossed.

 

Mine, too. I'd cross my toes, too; but there's not enough room down there to do that.
