The 2023 A6 is the quintessential Audi luxury sedan, featuring a cabin stuffed with technology that’s expertly put together using premium materials. Models wearing the 45 designation are powered by a turbocharged four-cylinder; all-wheel drive is standard, as is an eight-speed automatic. The A6’s 55-series models come with a punchy 335-hp turbocharged V-6, but a sports sedan this car is not. The A6’s handling is competent but coolly distant, delivering a more relaxed ride than more performance-focused competitors such as the Mercedes-AMG E53 or the Maserati Ghibli. The A6 is a more natural rival to other soft-riding mid-sizers like the BMW 5-series and Mercedes-Benz E-class. The A6’s styling may strike some as staid, so Audi offers the fastback A7 with a bolder fastback look; we review that model separately.
