Audi has unveiled the classic sedan version of the new A6, claiming it’s the most aerodynamically efficient combustion Audi ever.

The 2025 Audi A6 Sedan follows the A6 Avant wagon revealed in early March, available with a mild-hybrid petrol or diesel engine globally and no plug-in hybrid or fully electric options as yet.

While there’s nothing specific on the cards for Australia yet, the global headline details include a choice of three mild-hybrid engines.

The first is a 150kW/340Nm 2.0-litre turbo-petrol four-cylinder, which sips between 6.9L and 7.8L per 100km and allows for a 0-100km/h sprint of 8.2 seconds.

It’s joined by a 150kW/400Nm turbo-diesel four which is available with all-wheel drive and 204kW. It sips either 4.8-5.6L/100km (2WD) or 5.0-5.8L/100km (quattro) and can hit 100 in 7.8 or 6.9 seconds respectively.

The final choice is a quattro-only 3.0-litre turbo-petrol V6 with 270kW and 550Nm, which drinks between 6.7-7.7L/100km and hits 100km/h in a respectable 4.7 seconds.

While its design lends itself to a low drag coefficient of 0.23Cd - “the best value for a combustion-engine production model in Audi history” it says - the A6 also has optional adaptive air suspension and optional all-wheel steering.

The former is 20m lower in normal mode and a further 10mm lower in dynamic mode, while the latter allows the rear wheels to turn up to five degrees for more agility at low speeds or stability at high speeds.

Racing video games, car-spotting on road trips, and helping wash the family VL Calais Turbo as a kid were all early indicators that an interest in cars would stay present in Chris’ life, but loading up his 1990 VW Golf GTI Mk2 and moving from hometown Brisbane to work in automotive publishing in Melbourne ensured cars would be a constant. With a few years as MOTOR Magazine’s first digital journalist under his belt, followed by a stint as a staff journalist for Wheels Magazine, Chris’ career already speaks to a passion for anything with four wheels, especially the 1989 Mazda MX-5 he currently owns. From spending entire weeks dissecting the dynamic abilities of sports cars to weighing up the practical options for car buyers from all walks of life, Chris’ love for writing and talking about cars means if you’ve got a motoring question, he can give you an answer.
