Well, one of the potential concerns I had with my recent move to a 4RX450h, over the previous LR Discovery Sport, was how it would perform in snow & ice. Off road is something that really doesn't bother me, but the ability to stay mobile in bad weather when you live in a small village away from major routes is something that always concerns us. No such concerns with both the Discovery Sport and the previous RRS, and now no concerns with the RX. I put it into the recommended Eco setting (no Gravel, Sand or Snow setting on it like the Land Rovers) and it pulled off our drive, slight incline in 25cm of snow, with no trouble and handled the uphill bendy stretch out of the village as though there was no snow around.
A little bit of slip was present on the front wheels when exiting the drive but it was only momentarily as the AWD system quickly brought the rear wheels in to play. To be fair, the AWD system worked better than I thought it would.
Happy days
