Audi A6

The redesigned Audi A6 features lots of new technology, including a new infotainment system. Most versions come with a 2.0-liter, turbocharged four-cylinder engine; a 3.0-liter V6 engine with a mild hybrid system is also available. Both engines are paired with a seven-speed dual-clutch automatic transmission which is short on refinement at low speeds and the car hesitates before launch or from a rolling stop. In our tests the four-cylinder returned a commendable 26 mpg overall. The Audi's agile handling gives it a sporty driving experience. The ride is taut with underlying firmness but still comfortable. The quiet cabin is a delight in terms of fit and finish and the seats are extremely comfortable and supportive. The dual screen infotainment system is daunting at first, but we found it ultimately logical. Forward collision warning and automatic emergency braking are standard. Updates for 2020 brought a new high-performance S6 with a 2.9-liter V6 turbocharged engine mated to an eight-speed automatic transmission. The Allroad wagon returns and comes only with the 3.0-liter V6 turbo. For 2021 the Premium Plus got standard adaptive cruise control. There's also a new Sport 45 model, which includes a 13-hp boost compared to the standard four-cylinder engine (261 vs. 248). Finally, there's the RS 6 Avant wagon, powered by a 4.0-liter twin-turbo V8 matched with an eight-speed transmission. A mild update for 2024 brings a new grille, enhanced connectivity features, and a slight power increase for the RS 6.
