Audi S5 vs Audi RS 3

The RS badge only accompanies the sportiest version of a given Audi model, as demonstrated with the 2025 Audi RS 3. It differentiates itself from the Audi A3 and S3 sedans with a unique engine, sophisticated chassis tech, and bolder styling. The current-generation RS 3 was introduced for the 2022 model year, and for 2025 the RS 3 returns to Canada with updated chassis tuning that makes it even easier to drive fast, plus a subtle facelift.

Verdict: With its closest rival, the Mercedes-AMG CLA 45 S, on the way out, the RS 3 is in a class of its own. It combines four-door practicality, sports-car-rivalling performance, and an interior worthy of the Audi name. But you’ll pay a lot for all of that.
