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), a C8 generation executive saloon, is renowned for its blend of advanced technology, extensive options, and refined nature. Launched in the UK in 2018, it built upon its predecessor with subtle restyling, increased interior room, and significant under-the-skin changes, including 12- and 48-volt mild-hybrid powertrains, new suspension, and an updated touchscreen infotainment system. These enhancements aimed to maintain its competitive edge against strong rivals like the Mercedes-Benz E-Class, BMW 5 Series, Volvo S90, and Jaguar XF.

The A6 offers impressive interior space and practicality, including a 530-litre boot (though the plug-in hybrid reduces this to 360 litres), with an Avant estate option providing 565 litres. Driving is characterized by ease and impeccable refinement, making it an excellent long-distance cruiser, albeit less dynamically engaging than some rivals. Standard equipment is generous, even on base Sport models, with extensive options for customisation. Running costs are competitive for its class, with efficient diesel models achieving good real-world MPG, and various service plans available to manage expenses.

Best for: Drivers seeking a comfortable, capable, and technologically advanced executive saloon, excellent for long-distance travel, and those looking for sensible running costs (especially with diesel or plug-in hybrid options).

Not ideal for: Buyers prioritising a highly engaging or 'fun' driving experience (like a BMW 5 Series or Jaguar XF), or those who are budget-conscious regarding expensive optional extras.
