Explain to me what Torque-Vectoring is….

without telling me it’s a fancier way of saying Limited Slip-Differential

When a vehicle turns, the outer wheels has to turn more in relation to the inside wheel. There are different ways to achieve this with the most common mechanical way being a differential which is a set of gears that allows the inside and outside to rotate at different speeds.

Another way that a lot of vehicles are using to achieve this way is by applying brake pressure on the inside wheel to slow the inside wheel down and cause more of the power to be directed toward the outside wheel.

my understanding is that the Taycan accomplishes this with the combination of a traditional limited slip and a set of clutches at the rear that are capable of mechanically distributing torque on demand. This I believe is called PTV+.

Is it worth the cost is the question.

If you're not tracking the car and it's just a GT car, then probably no.

It is standard on Turbo and above. I have a feeling it may help the RWD get faster out of corners especially when grip is not perfect. I can’t see any material benefit for 4S (it has the lowest max torque on rear wheels and the help from front axle to pull it out of corners).

I think so… my first car with torque vectoring was a Giulia Quadrifoglio. So I’ve seen it before and knew a bit about what to expect. When you’re really pressing it through a sharper bend you can sort of feel it “push” the rear end through a corner. It almost feels like a mechanically induced slide at times. I have a 4S and I’d tick the box for sure. Compared to the RWD Giulia, it’s a little more subtle on the Taycan. Maybe b/c I have less power coming from the rear? I wouldn’t say you’re missing out by not having it. But I enjoy it and try to make use of it from time to time.

I optioned it on my RWD to get the mechanical LSD, but there's more to it.

From PAG_Taycan_Technology_PM_EN.pdf;
Porsche Torque Vectoring Plus (PTV Plus) uses an electronically controlled differential lock on the rear axle for variable distribution of the drive torque between the rear wheels. On the one hand, additional yaw torque can be generated on the rear axle by braking the inner wheel on the bend. This ensures that the vehicle’s steering response is even more agile. On the other hand, it improves traction by specifically locking the differential when accelerating out of corners.

Mechanical LSD. You mean the feeling of mechanical limited slip-diff?, which is technically more mechanical than PTV.

Seems like traction control is enough. Everything else is just added weight and trickery.

Um... is a Porsche Taycan worth the cost?
It's all worth the cost, if you've got the money.

Is the option worth the cost. I’m not too keen on paying $2000 extra to “get around the corners“ better. The car should be engineered to get around the corners as is.
Just seems gimmicky.

No.

The PTV in PTV+ is a mechanical LSD consisting of an electronically controlled clutch pack that limits torque to a wheel spinning faster than the other.
The + in PTV+ is braking the inner wheel for faster turn in, some would say gimmick.
I have PTV+ on both Taycan and GT4, and it's hard to say if they're even doing the + part, maybe if it was switchable I could feel the supposed benefit.

I thought PTV+ was software braking on the 911 and 718. Specifically on the Taycan, I thought the PTV+ was the LSD equipped with the clutch packs.

My GTS has both Rear Wheel Steering and PTV and it corners like a hot knife slicing through butter. You are buying a Porsche for the handling capability, I would option it. You are already spending a pretty penny on the car.
