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 and understated luxury saloon that offers a compelling alternative to the Mercedes-Benz S-Class and BMW 7 Series. Available in standard and long-wheelbase L variants, the A8 delivers exceptional interior quality, spacious rear accommodation, and a 505-litre boot. The range includes a choice of 3.0-litre petrol and diesel V6 engines, a plug-in hybrid 60 TFSIe with over 30 miles of electric range, and the high-performance S8 with 563bhp. All models feature quattro four-wheel drive, adaptive air suspension for a supple ride, and comprehensive driver assistance systems including semi-autonomous driving capabilities.

The A8 excels in perceived build quality, comfort, and refinement, making it ideal for those seeking a discreet yet lavishly equipped executive car. The plug-in hybrid offers significant tax and fuel savings for city-bound drivers, whilst the diesel 50 TDI provides excellent economy for longer journeys. Running costs are substantial but competitive with rivals, and fixed-price service plans are available through Audi dealerships. The 2021 facelift introduced digital matrix LED headlights and new rear OLED lights, further enhancing its technological appeal.

Best for: Wealthy buyers seeking understated luxury, those requiring a chauffeur-driven executive car, and business users who can benefit from the plug-in hybrid's tax advantages.

Not ideal for: Budget-conscious buyers, those prioritising fuel economy on longer journeys (except diesel models), or drivers who prefer simpler infotainment systems.
