Quick Summary

The Audi A6 (2019-2025), the eighth-generation C8 model, is a refined and technologically advanced executive saloon that combines comfort with capability. Launched in the UK in 2018, it offers a spacious interior with 530 litres of boot space (360 litres for plug-in hybrid models) and a comprehensive range of engines including efficient diesels, petrol options, and a plug-in hybrid variant. The cabin is superbly appointed with advanced infotainment systems, a 12.3-inch Virtual Cockpit, and an extensive array of safety features and driver assistance systems. Available in Sport, S line, Black Edition, and Vorsprung trims, the A6 provides something for most executive saloon buyers.

The A6 is an excellent cruiser with predictable handling and impressive refinement, making it ideal for long-distance driving. The 2.0-litre 40 TDI diesel delivers 201bhp and achieves around 52.3mpg combined, whilst the 261bhp 2.0-litre 45 TFSI petrol with quattro all-wheel drive offers more spirited performance. Running costs are competitive with rivals, and service plans are available to help manage expenses. Whilst not as engaging as the BMW 5 Series or Jaguar XF, the A6 excels as a competent, comfortable, and well-equipped executive saloon.

Best for: Buyers seeking a refined, comfortable, and technologically advanced executive saloon with excellent build quality and a wide range of powertrain options.

Not ideal for: Those prioritising dynamic driving engagement or seeking the most affordable running costs, and plug-in hybrid buyers needing maximum boot space.


Comparison vs Key Rivals



The Verdict

You should buy the A6 if: You're seeking a refined, comfortable, and technologically advanced executive saloon with excellent build quality and a wide range of powertrain options.

Consider alternatives if: You prioritise dynamic driving engagement, require maximum boot space with a plug-in hybrid, or want the lowest possible running costs.

Competitive Position: The Audi A6 (2019-2025) is a strong contender in the executive saloon segment, offering excellent comfort, refinement, and technology. Whilst the BMW 5 Series edges ahead with superior driving dynamics and the Volvo S90 impresses with user satisfaction, the A6 holds its own with its superbly appointed cabin, comprehensive safety features, and efficient engine options. It represents a sensible choice for those prioritising comfort and technology over outright driving thrills, competing well on value and practicality against the Mercedes-Benz E-Class.
