New 2025 Audi A6 Avant: price, specs & release date

Not everything’s electric – this is a new petrol and diesel-powered model from the prestige German brand.

It’s the new Audi A6 Avant, not to be confused with the A6 e-tron – which is fully electric. The new A6 is for customers who can’t or won’t jump to electric power, with a brace of conventional petrol and diesel options.

Both the 2.0-litre diesel and 2.0-litre petrol produce 204hp, although the diesel is noticeably quicker off the line – seven seconds to 62mph versus 8.3 seconds for the petrol – because it includes Audi’s quattro four-wheel-drive system.

The diesel engine also includes MHEV plus, a 48-volt mild-hybrid system coupled to a 1.7kWh battery. While we don’t know fuel economy figures yet, Audi tells us that the system enables low-speed manoeuvring and coasting on electric power. Strong brake regeneration and computer-controlled brake-by-wire tech work out when to use the motor to slow down and when to use the brakes.

Inside, there’s an 11.9-inch Virtual Cockpit digital instrument cluster and a whopping 14.5-inch OLED touchscreen that runs Android Automotive software. The voice assistant runs on ChatGPT artificial intelligence, and an additional touchscreen for the front passenger is fitted on the top-spec Edition 1 model.

Edition 1 is the top of three trim levels, with the range starting with Sport trim. This includes 18-inch alloy wheels, comfort-focused suspension, matrix LED headlights, four-zone climate control, surround-view cameras, adaptive cruise control, self-parking tech, wireless phone charging and a 10-speaker sound system.

S Line swaps the suspension for a slightly firmer, sportier setup, and also includes privacy glass, a sharper body kit and sports seats. Top-spec cars get 20-inch wheels, black exterior trim, red brake callipers and extra safety features.

Despite being almost five metres long and having an estate body style, the A6 Avant only offers a 503-litre boot – around 60 litres fewer than the outgoing model.

Prices start from £52,510 for a petrol Sport model, or £56,780 if you want a diesel. S Line is a £2,800 upgrade, and Edition 1 costs an additional £4,900, meaning prices of £60,210 for the petrol and £64,480 for the diesel.

10 colours are available, most being white, grey or blue, while there are also new leather colours and optional wheels up to 21 inches in size.

The 2025 Audi A6 Avant goes on sale on 1 April, with first deliveries taking place in mid-June.
