Which should you buy, 2020 or 2021? For the A4 and S4, a 2021 is the better bet if 2020 prices remain the same at dealerships. The added standard features in the A5 and S5 also make the price increases seem modest and worthwhile, and there’s a new more affordable Sportback option.
Audi’s 2021 A4, A4 Allroad, S4, A5 and S5 gain some interesting powertrain updates, a new base model for the A5 Sportback and some reconfigured features depending on trim level.
