So I am interested in an Audi Etron SUV, but confused on which one to pursue? What is difference between a E-tron SUV, E-Tron Sportsback, Q4 Etron and Q8 Etron? I noticed the first 2 models only have 225 mile range and last 2 I think do 265 mile range. Also are all these 2023 models right now or any of them 2024 as well?
