Personally, I test drove the RWD and was not impressed. Then, I bought the AWD, and I'm impressed. The car feels completely differently to me with the AWD. It feels like it has plenty of power in reserve, not that I want to floor it. I have a similar feeling (power-wise) with my Tesla Model Y. I never gun it, but on a rare occasion when necessary, it behaves effortlessly when I give it a nudge to accelerate. I don't drive in the snow much, but Maine being a rural state, I'm sure if you venture outside your town, you will have plenty of places where you would wish you had an AWD. Whether or not the RWD will get stuck in the snow - that all depends on how far off the beaten path you want to venture in the winter. If you stay on cleared roads, I'm sure you will be okay with the RWD.There is the ID.4, which has the 62 kWh battery and, like you said, cloth seats, manual seats, etc.
Then there is the ID.4 S, which has the 62 kWh battery but upgraded features (leatherette seats, power seats with memory, heating steering wheel, etc). This one starts at $42,495. <-- this is what I reserved.
If there is "Pro" in the name, it means it has the 82 kWh battery. There is the ID.4 Pro (RWD). Pretty basic in terms of features (cloth seats, etc) but same price as the ID.4 S: $42,495. Moving up there is the Pro S and then the Pro S Plus (AWD).
Like you, I thought I had to have AWD because I am in Maine, but I have read enough posts on this forum that say the RWD works just fine in winter that I am going to take a chance on that. I am also going with the smaller battery because I think for the way we drive 99% of the time it will be fine. My husband was balking at the $50K price for the AWD Pro S I had reserved so maybe this lower price will be more palatable.
I have a feeling there will still be lots of time to think about all this...
The best illustration of my opinion about the RWD vs the AWD in the ID.4 is that if I owned a taxi company and wanted to equip it with EVs, I would certainly go for the RWD ID.4 fleet of taxis regardless of the climate. But, for myself, I am just as sure that the AWD is the way to go.
