Audi A8 (2018-present) Pros and Cons

Pros	Cons
Exemplary interior quality	Predictably expensive
Super-spacious long-wheelbase L models	The S8 drinks fuel fast if you make full use of its performance
Relatively discreet and understated	Infotainment not the easiest to use

Quick Summary

The Audi A8 (2018-present) is a technologically advanced, understated luxury saloon, available in standard and long-wheelbase 'L' versions for enhanced rear passenger space. It boasts impeccable build quality, a sumptuous interior, and a 505-litre boot (350 litres for PHEV), though the opening is shallow. All models feature quattro all-wheel drive and adaptive air suspension, ensuring a comfortable ride befitting its luxury status.

Engine options include 3.0-litre petrol and diesel V6s, and a 60 TFSIe plug-in hybrid offering over 30 miles of electric range and tax benefits. The high-performance S8 packs a 563bhp V8. The A8's cockpit is packed with tech, including a virtual cockpit and dual touchscreens, alongside a comprehensive suite of driver aids. While predictably expensive to buy and run, the PHEV and diesel variants offer more economical choices, making it a compelling alternative to rivals.

Best for: Buyers seeking understated luxury, advanced technology, chauffeur-driven comfort (especially A8 L), or those who can maximise the tax benefits of the PHEV.

Not ideal for: Budget-conscious buyers, those who prefer simpler infotainment interfaces, or families needing a very practical boot with foldable rear seats.


Comparison vs Key Rivals



The Verdict

You should buy the A8 if: You seek understated luxury, advanced technology, a comfortable and spacious ride (especially the L model for rear passengers), or wish to benefit from the tax advantages of the PHEV variant.

Consider alternatives if: You are on a strict budget, prefer a more intuitive infotainment system, or require a boot with a wider opening and foldable rear seats for maximum practicality.

Competitive Position: The Audi A8 (2018-present) stands as a strong alternative to the Mercedes-Benz S-Class and BMW 7 Series, offering a compelling blend of elegant design, premium build quality, and advanced technology. While its infotainment might require some acclimatisation and boot practicality is limited by its saloon design, its comfortable ride, range of efficient powertrains, and discreet luxury make it an attractive choice for those who appreciate sophistication without ostentation. The S8 further offers a high-performance option.
