Dang axel, you have convinced yourself and refuse to hear/see anything that contradicts your perception. That's a characteristic of a true leftist.Sorry I did not meant to offend anyone. The RS does not have brake-based torque vectoring. Just get over it.....
Just so you know a bit about me; I'm an experienced autocrosser and drag racer with oh, about 50 years of experience myself. I've own the (2014)FiestaST, (2017)FocusRS, and (2018) Raptor vehicles of the current Ford Performance line. Also owned an older FWD Ford and autocrossed it for 17 years. I've lived in South Dakota and raced FWD on the ice of Stockade Lake as well. Quite fun! The brake-biased torque vectoring (traction control) works just fine on the FocusRS as it does on other Ford vehicles. It does NOT intervene as a hard pulsing like the ABS. It is a much more smoothly applied brake force. It does NOT stop wheelspin, it only slows it enough to keep the drive functioning and the car moving. It is VERY smooth compared to throttle-based traction control that will sometimes close the throttle abruptly. Mazda uses a very similar brake AND throttle based system to assist in turn-in and traction control. It's VERY smooth. Oh, I have owned a few Mazdas as well, currently on my ~3rd CX-9, the latest a 2019 GT.
PS, the quotes I posted earlier were from the 2017 FocusRS Owners Supplement here:
2017 Focus RS (CEW) RS, Canada/United States of America, HM5J 19A285 DA enUSA, Edition date: 201611, First Printing
Feel free to do your own research to dispute what the writing and my driving experience says. You should install temp sensors near the brake rotors, then go out on your wet driving spree and watch the front brake temps when you spin the inside front out of corners,. You will indeed see the brake temp on that spinning wheel increase rapidly.
Yeah I'm old and I know things...
