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 improved interior space compared to its predecessor, with 530 litres of boot space (360 litres for the plug-in hybrid variant) and a superbly appointed cabin. The A6 features a comprehensive range of engines, including efficient 2.0-litre diesel and petrol options, plus a plug-in hybrid TFSI e variant, all paired with advanced driver assistance systems and an intuitive touchscreen infotainment system.

The A6 is an excellent cruiser with predictable handling and impeccable refinement, making it ideal for long-distance driving. Whilst not as engaging as the BMW 5 Series or Jaguar XF, it compensates with superior comfort and a wealth of technology. Running costs are competitive for the executive saloon segment, with the diesel variant achieving around 52mpg on the combined WLTP cycle and real-world figures in the mid-40s. Service plans are available to help manage expenses, though buyers should be mindful of premium tyre costs on larger wheel options and the potential expense of optional extras.

Best for: Drivers seeking a refined, comfortable, and technologically advanced executive saloon; those prioritising comfort and practicality over driving dynamics; and buyers wanting a plug-in hybrid option.

Not ideal for: Those wanting an engaging, fun-to-drive executive saloon; buyers seeking maximum boot space with a plug-in hybrid; or those looking to minimise 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; you prioritise comfort and practicality over driving dynamics; or you want a plug-in hybrid option.

Consider alternatives if: You want an engaging, fun-to-drive executive saloon, maximum boot space with a plug-in hybrid, or wish to minimise optional extra costs.

Competitive Position: The Audi A6 (2019-2025) is a strong contender in the executive saloon market, offering exceptional comfort, advanced technology, and a comprehensive engine range. Whilst the BMW 5 Series edges ahead with superior driving dynamics and a marginally higher overall rating, the A6 competes favourably with the Mercedes-Benz E-Class and Volvo S90. Its superbly appointed cabin, efficient powertrains, and extensive safety features make it an eminently sensible choice for those prioritising refinement and practicality. The plug-in hybrid variant adds environmental credentials, though buyers should be aware of reduced boot space and the potential cost of optional extras.
