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 tailored for suburban families, offering the desirable Audi badge and ample rear passenger space. However, its boot capacity is surprisingly small for its class, being less roomy than the previous generation and significantly reduced in diesel and PHEV variants, with the latter comparable to a Renault Clio. This is a notable drawback for a family estate, despite its otherwise practical and spacious cabin for occupants.

The A6 Avant comes with three four-cylinder engine options (petrol, mild-hybrid diesel, PHEV), all featuring a seven-speed S Tronic automatic gearbox and available quattro all-wheel drive. It excels at long-distance cruising, providing a smooth ride, especially with optional air suspension, and impressive suppression of wind and road noise. While the interior is generally slick with generous standard technology, the infotainment system's climate controls can be fiddly. Pricing starts competitively, though the PHEV versions may incur higher company car tax compared to some rivals.

Best for: Families seeking premium badge appeal and passenger space, long-distance motorway cruising, buyers looking for a well-equipped entry-level model.

Not ideal for: Buyers prioritising maximum boot capacity, those sensitive to fiddly infotainment controls, company car drivers considering the PHEV for tax benefits.


Comparison vs Key Rivals



The Verdict

You should buy the A6 Avant if: You value premium badge appeal, comfortable long-distance travel, and ample passenger space, and are willing to compromise on ultimate boot capacity.

Consider alternatives if: Boot space is a top priority, you prefer physical climate controls, or you require a plug-in hybrid with lower company car tax.

Competitive Position: The Audi A6 Avant (2025-present) is a stylish and comfortable premium estate that offers a desirable badge and a high-quality interior experience. While it falls short on boot capacity compared to rivals like the BMW 5 Series Touring and Mercedes-Benz E-Class Estate, and its PHEV might not be the most tax-efficient, its competitive starting price for conventional models and excellent passenger comfort make it an attractive option for those prioritising luxury and refinement over ultimate cargo space.
