In a first drive of the 2025 Audi RS3, Jalopnik praised its powerplant as "one of the most entertaining and characterful engines on sale." However, Audi didn't offer the RS3 for the 2021 model year, so we'll need to dial it back to 2020, which was the last year of the previous 8V generation. The 2020 RS3 held on to most of its value, but even a conservative six-year depreciation estimate of 18% means a five-figure difference between a 2020 RS3 and one from 2026. To get a better idea of the number crunching, we'll look at valuations from CarEdge and Kelley Blue Book (KBB). More importantly, we'll examine what a 2020 Audi RS3 sells for in today's market — arguably a more accurate look at depreciation.
