Have an 04 G35 Coupe that had S Drive summer tires on it and it was great fun in the twisties!!!!
I put on Conti DWS's in case we got some snow. Plus they were supposed to be performance tires.....side walls are like jello....no fun. Anyway, no good in the snow for me. I like something that I don't have to white knuckle drive and would not drive it to work in the snow!!!!!
Our 08 G35X is fantastic in the snow!!!
Highly recommend! It also has the DWS's, but the AWD makes the difference.
I've owned several 4x4 SUV's (Bronco II, Exploder, Pathy's) and the G35X does better than all in the snow in my opinion.
However, the SUV's with low range and limited slip did better in the sand.....well, actually haven't tried the G35X in the sand...wife won't let me bolt a fishing rod holder to the front bumper!!
hope my .02 helps
