I got to try both the Golf R 2016 and 2018 version plus the TL and TLX SH-AWD recently, only the TLX in winter and Golf R in the summer though
here has been report stating the traction control cannot be fully switched off on the 2016 model but the 2018 fixed that, however I cannot confirm or reject that claim since they both behaved much like a front wheel drive and understeer when I put the power down midway through a corner, the front pushes and it drive much like a front bias car to me, reminds me a lot of my old subaru outback in winter.
TLX & TL SH-AWD
Drove both only with snow on the ground, preferred the TL SH-AWD with manual transmission, I think they stopped making them in 2014.
the 2016 TLX I test drove is very slow to shift from 1st to 2nd and 2nd to 3rd, sales people said it was a known issue and they fixed that in recent year model, biggest issue I have with the TLX is that it is very unpredictable, giving it power in slippery condition undergoes perfect grip --> understeer --> perfect grip --> oversteer, to get more grip when the front start to push, you have to give it power and that throws most people driving habit off in my opinion.
Although I haven't test it out, I do believe Golf R can do power oversteer at low speed turn from get up and go city commute, that can't be said on the TL and TLX I test drove last winter, they both are somewhat unpredictable, with the TLX being the worse of the two.
