Audi A6 Avant (2025-present) Pros and Cons

Pros	Cons
Low levels of wind and road noise	Boot is small by class standards
Lots of space for passengers	Interior quality not as good as previous A6
Smart styling helps it to stand out	Limited engine range

Quick Summary

The Audi A6 Avant (2025-present) is a premium estate car that combines elegant styling with a smooth, refined driving experience. It offers generous passenger space with excellent rear legroom and head room, making it ideal for families and long-distance travel. The car features a well-equipped interior with modern technology, including adaptive LED headlights, adaptive cruise control, and a comprehensive infotainment system with Apple CarPlay and Android Auto. Three powertrain options are available: a 2.0-litre petrol TFSI with front-wheel drive, a 2.0-litre diesel TDI with four-wheel drive, and a plug-in hybrid e-hybrid variant offering up to 63 miles of electric-only range.

However, the A6 Avant has notable drawbacks that undermine its appeal as a premium estate. The boot is surprisingly small for its class at just 503 litres (466 litres for diesel, 404 litres for PHEV), falling short of rivals and even smaller than the previous generation. Fuel economy is modest, with petrol models achieving 30-35mpg and diesel around 40-45mpg in real-world driving. The mild hybrid system can exhibit juddering at low speeds, and the plug-in hybrid incurs significantly higher company car tax than competitors. The interior quality has also declined compared to the previous A6 generation, and the climate control system, accessed via touchscreen rather than physical controls, can be fiddly to operate whilst driving.

Best for: Buyers seeking a premium, quiet, and comfortable estate car for long-distance motorway driving, those prioritising passenger space and elegant styling, and company car users considering the petrol or diesel variants.

Not ideal for: Those requiring maximum boot space, budget-conscious buyers seeking excellent fuel economy, company car users considering the plug-in hybrid, or those preferring intuitive physical controls for climate functions.


Comparison vs Key Rivals



The Verdict

You should buy the A6 Avant if: You prioritise a quiet, refined, and comfortable driving experience for long-distance motorway journeys, value elegant styling and premium badge appeal, and require generous passenger space.

Consider alternatives if: You need maximum boot capacity, seek excellent fuel economy, are considering the plug-in hybrid as a company car, or prefer intuitive physical controls for climate functions.

Competitive Position: The Audi A6 Avant is a capable premium estate that excels in refinement and passenger comfort, but falls short of its rivals in key areas. Whilst it undercuts the Mercedes-Benz E-Class and BMW 5 Series Touring on price, it struggles with a surprisingly small boot and modest fuel economy. The Volvo V90 offers superior user ratings and is limited to plug-in hybrid form, whilst the BMW 5 Series Touring and Mercedes-Benz E-Class both score higher with experts and users. For buyers prioritising boot space and efficiency, these rivals present stronger cases, though the A6 Avant remains an attractive choice for those valuing refinement and style over practicality.
