Audi Q4 RWD vs AWD
 

Hey everyone. First of all surprised, I didn't see a Q4 subforum but if I missed it, please let me know.
Now to my question. I'm looking at 2023 Q4 e-Tron models and was comparing different trims.
Can anyone tell me why 40 e-tron® Premium Plus (RWD), has 29 miles better range than 50 e-tron® Premium Plus? Is it due to the AWD needing more energy? The batteries as far as I know are identical.
Also, can anyone chime in on experience in driving RWD vs AWD in a 1-4 inch snow as far as taking off and stability traction? Tryin to decide if AWD is worth the premium.

Thanks!
