With the market shift to SUVs, F is going to need to take on some extra ground clearance and come up with a performance AWD system. We have GLC 43, GLE 43, GLC 63, GLE 63, Macan turbo, Macan GTS, Cayenne turbo, Cayenne GTS, SQ5, X3 M, X5 M, X4 M, X6 M, SQ7, etc. etc.
Even Acura is on the verge of TT V6 with SH-AWD in MDX and other vehicles.
This is simply the future, so Lexus needs to have a plan sooner rather than later.
Good news is with TNGA philosophy and some of their new hardware, I think they can do this without much problem.
Based on what we know, Dynamic Torque Vectoring AWD is actually superior to the AWD system Lexus uses in new LS 500, so that bodes well for the future of things like NX, RX and ES.
