The 2025 Audi A6 is built for quiet luxury with a clean, unadorned design that's the polar opposite of splashy. While there’s nothing wrong with its base 261-horsepower four-cylinder, we much prefer the available 335-horsepower V-6, as it makes highway jaunts effortless and provides good power for spirited driving. If you need more than that, consider the high-performance S6 model (reviewed separately), which keeps the stealthy look but sharpens its responses to go along with a 444-horsepower engine. This comfortable sedan has strong competition in the BMW 5-series, the Genesis G80, and the Mercedes-Benz E-Class, all of which are well-built and offer plenty of tech. If you like the size of the A6 but want to make the switch to something powered by electricity, check out the A6 e-tron which is new this year and built on an electric-vehicle architecture. As one of our favorites in its segment, the Audi A6 has earned a spot on our Editors’ Choice list for 2025.
