The Audi A6 was largely revised and improved for 2019. This year, prepare for an onslaught that includes a 248-horsepower, turbocharged 2.0-litre four-cylinder engine, the adventurous A6 allroad featuring a 335-horsepower, turbocharged 3.0-litre V6, the sporty S6 sedan with a 444-horsepower, twin-turbocharged 2.9-litre V6 and the almighty RS 6 Avant wagon whose twin-turbo 4.0-litre V8 produces 590 horsepower. Oh, and a plug-in hybrid variant with an EV range of about 40 km is also on the way!
