Default Torque Vectoring?

Hey guys,
Just curious, does anyone know which cars have active torque vectoring? Just curious and trying to figure it out. Been doing some off roading in my 2014 crosstrek (5MT) but usually I find best traction with TC off and trying to gun it if the traction is bad. However if it has torque vectoring then I would think it would be best to just slowly spin the tires and let the car try to vector tot better.

Thanks for your input!

Torque vectoring was not introduced until the 2015 WRX/STI.

Actually, no Subaru has torque vectoring. Any use of that term is marketing bs. Some models have BRAKE vectoring. Meaning the front inside wheel is slowed by the traction control system. The 2008+ WRX has open front/rear differentials, so true torque vectoring is not possible.

Both replies above are correct.

It's not real torque vectoring, as it can only apply negative torque. It can only actuate the brakes at each wheel, applying negative torque (defining our coordinate system such that positive torque produces forward motion of the car). True torque vectoring can apply positive or negative torque, and is easier to implement in electric cars with independent motors.

I also believe that the 2015 WRX was the first to have brake vectoring. I can positively confirm that my 2015 WRX has brake vectoring, and it works amazingly well! I get better autocross times in my WRX than my 350Z, and I have NEVER been able to get my WRX stuck in either snow or mud.

For real torque transfer you need real diffs. So if you want it, you'll have to get off the wallet.

Front diff: Requires trans rebuild and are hard to find.
Center diff: Your stocker transfers power to the front at 4kg. Rebuilds can go to upwards of 50kg but finding a rebuilder is very hard.
Rear diff: Easyish swap with more options.

If you are cereal, you'll want to work with a rally shop as those are the only ones with experience in this.

I put a PPG Torsen front and Cusco 1.5 way in rear in my wagon because daily driver + idiot owner so I can vector while I vector. Not smart but I never claimed to be. Would like new center but hard to source.
