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 the plug-in hybrid), impressive cabin quality, and a comprehensive range of engines including efficient diesels and a plug-in hybrid option. The car delivers excellent refinement for long-distance driving, with predictable handling and a composed ride, though it prioritises comfort over dynamic engagement.

The A6 comes well-equipped across all trim levels, from Sport through to Vorsprung, with advanced driver assistance features and modern infotainment systems standard. Running costs are competitive for the executive saloon segment, with the diesel variant achieving around 52mpg combined and real-world figures in the mid-40s. Service plans are available to help manage expenses, and residual values remain strong. As a used car, it represents a sensible choice for those seeking a refined, capable, and well-appointed executive saloon with practical everyday usability.

Best for: Buyers seeking a refined, comfortable executive saloon with advanced technology, those prioritising practicality and interior space, and drivers wanting efficient running costs with multiple powertrain options.

Not ideal for: Those wanting dynamic, engaging driving dynamics comparable to a BMW 5 Series or Jaguar XF, buyers concerned about plug-in hybrid boot space reduction, or those wishing to avoid expensive optional extras.


Comparison vs Key Rivals



The Verdict

You should buy the A6 if: You're seeking a refined, comfortable executive saloon with advanced technology, prioritising practicality and interior space, or wanting efficient running costs with multiple powertrain options.

Consider alternatives if: You want dynamic, engaging driving dynamics comparable to a BMW 5 Series or Jaguar XF, are concerned about plug-in hybrid boot space reduction, or wish to avoid expensive optional extras.

Competitive Position: The Audi A6 (2019-2025) is a strong contender in the executive saloon segment, offering excellent refinement, spacious accommodation, and comprehensive technology. Whilst the BMW 5 Series edges ahead for dynamic driving engagement and the Volvo S90 offers superior value, the A6 strikes an impressive balance between comfort, capability, and practicality.
