Audi A6 vs Mercedes-Benz C-Class

The redesigned 2026 Audi A6 marks the ninth generation of midsize luxury sedans from Ingolstadt, Germany. While it shares a name and some tech features with the Audi A6 e-tron introduced for the 2025 model year, the gasoline A6 is an otherwise different vehicle based on the same Premium Platform Combustion (PPC) as the A5 sedan and Q5 crossover. A redesign was certainly needed as most other midsize luxury sedans—specifically the BMW 5 Series and the Mercedes-Benz E-Class—were renewed more recently, and we haven’t had a genuinely new A6 since the 2020 model year.

Verdict: On paper, the A6 looks like more of a premium product than before, but it doesn’t feel that way from behind the wheel, and the tech is a work in progress.

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, the BMW 3 Series, the Lexus IS, and the Volvo S60 are fixtures in this segment, with nameplates that date back at least two decades. The Acura TLX, the Cadillac CT4, and the 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, and in Canada, 4Matic all-wheel drive (AWD) is standard while rear-wheel drive (RWD) is not offered. Our test car was a C300 4Matic with a long list of optional equipment. 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.
