The vehicle when fully charged says 53kms. I do set it to be in pure EV mode but depending on what other accessories you are running (i.e. heated seats, heated steering wheel) it does seem to start the engine but the flow shows that it is charging the battery, not driving the vehicle which is interesting.
So far we have been lucky here in Edmonton, Alberta that we have had no snow or ice, the lowest temperature has been -6 so I haven't really had a change to see how it would be on snow.
The vehicle really does try to keep itself in EV mode if that is what you set it to and only does run the engine when it has to. I still haven't completly figured it out as sometimes I will have the heated seats and heated steering wheel on and it will stay in EV mode, other times, with the same situation, the engine comes on an charges the battery, perhaps that is when the heated seats are getting warmed up again.
I have never had a PHEV so it has been an interesting 250km with it. I am still not used there being no engine noise when it is in EV mode, I guess I am so used to the sound of an engine it seems very very strange. A few things have been weird like you can't use the garage door opener unless the vehicle is running but just have to get used to a different way of doing things.
Over all I am very very impressed with Hundai. In the past I have only had Cadillac and Lincoln so I was not really sure what to expect but so far the vehilce and all of its features have very much impressed me.
