What is the general consensus?

personally I’m a V8 fan. I agree the new model looks attractive (not the 2019 because the back looks like a Durango or Lincoln which reminds me of the Chris Bangle designed Bimmers that look like a Hyundai from the back) but the V8 sound is always better than a V6.

Interesting, thanks guys. Currently I have a 957 V8 and I adore that engine, sounds awesome, super reliable and pulls like an ox, so I am biased. But the goal here is to update and I feel like going to a 2013 just to keep the V8 is a half measure as the rest of the car has been updated further in the 2016-17s. I just feel that the V6 TT will be a disappointment

Back to this topic, any experiences with towing with the new generation V6TT vs V8 or even diesels?

Not a comparison to diesel or v8, but I have towed pretty extensively with my ‘16S with air suspension.
- plenty of power, and torque builds nicely and predictably
- brakes are solid
- air suspension is awesome and controlling things

I’ve towed heavy utility trailers, car trailers (u-haul) with old trucks on them, etc. I think the car trailer plus truck was nearing 6k lbs. Other than needing to take it easy and recognize how heavy the load is, the Cayenne behaved incredibly well. The torque of the v6tt is really quite nice. I know it isn’t quite as strong as diesel, but no slouch. Far better than my previous tow rigs (Lexus gx470, 4Runner, etc.).

I'm in a similar boat. Initially I thought I wanted the V8 so I restricted my search to '13-'14 models, but then I took a face lifted 2015 S V6TT for a spin and really liked it. I currently have a 955 V8 and I was worried that I won't like the V6, but the 958 V6 is lighter, has more power and as long as you can live without the V8 sound, I think overall it is a better choice.

I just switched from a 2011 S with V8 to a GTS w V6 (3.6). I wanted air suspension which is hard to find on the S.

Both car car have the same problem, in normal setting the transmission is programmed to save fuel so waits too long to downshift. I always drove the S in sport settings. The new GTS I drive in normal but use paddles to downshift as it will be in 8th gear at 40-45mph. The sport setting just sips fuel like tomorrow in the GTS. I towed to with the S and always used sport setting when towing. Less gear hunting. My opinion is, there is not too much difference in the engine to be the determinate factor, look for other options that are your must haves. It is the transmisssion that is the Achilles heel for the car.
