The Sportage AWD has a button just like the Seltos where you can lock the AWD in a 50:50 lock.
It does unlock at higher speeds, and on the Seltos it will also unlock if the steering wheel is turned to a significant angle. I believe both systems are identical, but they are definitely very similar.
peter is really good at his kia vehicle videos . he works out of brantford kia in canada so be careful if your comparing trim names from canada v.s usa . I think the lx fwd in canada is the S in usa ....for example.
