Hello, I'm curious what PVT does on a Macan, and if its necessary for performance. It seems its for low traction conditions but does it do anything on "canyon roads"? Anyone not have the vectoring and want it?

 

From Porsche's website about PTV:

https://presskit.porsche.de/specials...-ptv-plus.html

I didn't get it on either of my Macans because I never plan to track it or do very high performance driving with it, so I just don't think it's really necessary or beneficial for every day driving, even spirited driving.

 

I have it on mine...whether I can tell the difference or not is hard to say, I've never pushed any Macan other than mine hard enough to find out - which tells you how little it does during normal day to day driving.

 

Looks to me like Porsche's variant of a limited slip differential. I have always had this option on my BMW's in the past, and I think it helps gain traction pulling hard out of corners. Not sure what it will do in a 4WD Macan, but I think it tends to lock L/R axles in addition to F/R axles in the FWD system. Probably more complex than that due to all the electronic control these days, but whether it helps you in the dry depends on how aggresive you drive on the street.

 

I had PTV on my 2019 Carrera T. I liked the idea of it, seemed to make sense etc... but I didn't really know if it made a difference in how the turned. Who knows as I couldn't turn it on and off.

Downside = could go through brake pads faster in the rear? Hmm...

 

I think Nick Murray (YouTube guys) bashed PVT on Macan (PVT on AWD SUV, he praised PVT on RWD 911/718s). AWD get power and catches grip so he didn't think PVT is necessary on Macan.
I don't have it on my Macan as I don't even push nearly enough on 911.

 

The feature is called "Porsche Torque Vectoring" aka PTV. Yes, it does help in cornering, in conjunction with Porsche's electronic limited slip differential. These features act seamlessly such that you're most likely not aware they're functioning. If you could drive a vehicle without these features back-to-back with one that does, you'd probably notice a difference.

 

Had OEM LSD on my 993 till it wore out at around 60K. Replaced with Guard LSD, and noticed with just moderately aggressive driving. The Guard was such an impressive piece I kept it on my coffee table till Wife said way past time to get it installed.

Honestly can't tell when the PTV is working, even in very aggressive canyon carving. Only know that I avoided going in the canyon.

 

Nick Murray is the last cuck you should listen to for buying advice on Porsche's...he has some really bad opinions.

 

Porsche club guys here in UT seem to feel PVT leads to faster tire wear without commensurate handling improvement. But I've never specced it.

 

I thought it was brake wear?

 

yep ask anyone who tracks their 911 so equipped ... esp bad since most tracks consist of effectively a LOT of right or left turns!!!

 

I think tire wear depends on the locking percentage. The higher the locking percentage, the more tire scrubbing occurs when in tight cornering. But there is no doubt limited slip differentials improve performance, because you have both rear tires driving out of corners (and straight) instead of one. In American car jargon, these were marketed as "posi-traction". When auto crossing, they also reduce inner wheel spin in tight corners, esp if that wheel breaks traction due to inner wheel lift.
