Audi A6 (2019-2025) Pros and Cons

Pros	Cons
Wide choice of engines, including a plug-in hybrid	Not as much fun as rivals from BMW and Jaguar
Comfortable and superbly made cabin	Reduced boot space if you choose a plug-in hybrid
Fully loaded with high-tech safety features and driver aids	Some optional extras are expensive

Quick Summary

The Audi A6 (2019-2025), the eighth-generation C8 model, is a refined and technologically advanced executive saloon that blends comfort with capability. Launched in the UK in 2018, it offers substantial interior space with 530 litres of boot capacity (360 litres for the plug-in hybrid), alongside a comprehensive range of engines including efficient diesels, petrol options, and a plug-in hybrid TFSI e variant. The cabin is superbly appointed with advanced infotainment, a 12.3-inch Virtual Cockpit, and an extensive array of driver assistance features, making it an appealing choice for those seeking a competent and sleek executive saloon.

The A6 is easy to drive despite its size, offering impeccable refinement and predictable handling that makes it an excellent long-distance cruiser. The 2.0-litre 40 TDI diesel delivers 201bhp with sensible performance, whilst the 261bhp 2.0-litre 45 TFSI petrol with quattro all-wheel drive provides more spirited acceleration. Running costs are competitive within the executive segment, with the diesel achieving over 52mpg on the combined cycle and real-world figures in the mid-40s. Service plans are available, and residual values should remain strong, though buyers should be mindful of premium tyre costs on larger wheel options and the potential expense of optional extras.

Best for: Buyers seeking a refined, comfortable, and technologically advanced executive saloon with practical space and efficient running costs, particularly those valuing comfort over driving excitement.

Not ideal for: Drivers prioritising engaging handling and driving thrills, or those seeking maximum boot space with the plug-in hybrid variant, or budget-conscious buyers wary of optional extra costs.


Comparison vs Key Rivals



The Verdict

You should buy the A6 if: You're seeking a refined, comfortable, and technologically advanced executive saloon with practical space and efficient running costs, particularly valuing comfort over driving excitement.

Consider alternatives if: You prioritise engaging handling and driving thrills, require maximum boot space with a plug-in hybrid variant, or wish to avoid potentially expensive optional extras.

Competitive Position: The Audi A6 (2019-2025) is a strong contender in the executive saloon segment, offering excellent refinement, comprehensive technology, and practical space. Whilst the BMW 5 Series edges ahead with superior driving dynamics and the Mercedes-Benz E-Class offers marginally better value, the A6 remains an eminently sensible choice for those prioritising comfort and capability. The Volvo S90 provides comparable luxury and user satisfaction, but the A6's wider engine choice, including the plug-in hybrid option, and advanced driver assistance features make it a compelling proposition for discerning buyers seeking a well-rounded executive saloon.
