Mercedes-Benz C-Class vs Audi A3

For just a little more money, you can trade the 2025 Audi A3 sedan’s superior performance, nimbler handling, and better fuel economy for the Audi Q3 crossover SUV’s additional interior room, cargo space, and ride height. It’s a deal most people make; Audi sells over three times the number of Q3s that it does A3s. Perhaps changes to the refreshed 2025 A3, including the newly standard Quattro all-wheel-drive (AWD) system and additional standard features, will sway more Audi customers toward the sedan.

Verdict: Small, speedy cars like the 2025 Audi A3 are a lot fun. While you can upgrade performance with the Audi S3 or RS 3 models, the standard A3 equipped with the Black Optic Package is a delightful companion on any twisty road. Quality materials, modern tech, and practical packaging make it even better.

The Mercedes-Benz C-Class was the automaker’s entry-level model, but it needed a new role. Mercedes now has a line of compact cars serving as lower-priced entryways to the brand, so it’s moving the C-Class upmarket. The redesigned 2022 Mercedes-Benz C-Class sedan borrows design elements from the automaker’s flagship S-Class to entice new car buyers on a budget who still want the most Mercedes for their money.

The C-Class competes against a formidable array of small sports sedans. Like the Mercedes, the Audi A4, BMW 3 Series, Lexus IS, and Volvo S60 are fixtures in this segment, with nameplates that date back at least two decades. The Acura TLX, Cadillac CT4, and Infiniti Q50 are newer names that build on their respective brands’ experience in the segment. The Genesis G70 is a relative newcomer from a recently launched brand that’s already managed to impress.

The all-new C-Class launches in C300 sedan form with standard rear-wheel drive (RWD), optional 4Matic all-wheel drive (AWD), and Premium, Exclusive, and Pinnacle trim levels. Our test car was a C300 4Matic in the top Pinnacle trim. An AMG C43 performance model is also on the way, but it’s not expected to hit showrooms until after the C300, which arrives at dealerships later this spring.
