Audi A6 vs Audi S5

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 S5 is the performance version of the A5, a compact luxury car equipped with a handy Sportback design that offers more utility than a traditional three-box sedan. With the 2026 S5, Audi attempts to right some technological wrongs, returning familiar controls to the car while introducing an all-new Multi Media Interface (MMI) infotainment system with AI-enhanced voice controls. Complimentary scheduled maintenance is a new ownership perk, too.

Verdict: Dull design and distracting technology are the trade-offs for the 2026 Audi S5’s thrilling dynamics and daily driver practicality. Nevertheless, the stealthy anonymity draws from a classic German sports sedan recipe, and buyers can choose not to use certain features.
