Audi Q8 (2018-present) Pros and Cons

Pros	Cons
Outlandish looks and huge presence	Very expensive to buy
Fabulous cabin quality	Audi doesn't usually perform well in reliability surveys
Satisfying to travel in for both driver and passengers	An Audi Q7 is the more practical, rational buy

Quick Summary

The Audi Q8 (2018-present) is a statement-making luxury SUV that combines outlandish styling with exceptional interior quality and impressive performance. With a 605-litre boot, spacious rear seating, and a range of potent engines including 3.0-litre V6 petrol and diesel options, plus the formidable SQ8 with its 507bhp 4.0-litre twin-turbo petrol unit, the Q8 delivers both presence and capability. The height-adjustable air suspension and adaptive dampers provide excellent ride control, whilst the vault-like cabin offers a serene, civilised driving experience suitable for long-distance grand touring.

Inside, the Q8 showcases cultured luxury with deeply cushioned leather seats, brushed aluminium veneers, and a trio of digital infotainment screens creating a theatrical experience. Running costs reflect its premium positioning, with the 50 TDI diesel achieving 33.2 mpg and the 55 TFSI petrol managing 26.4 mpg. Insurance sits in Group 47 for V6 models, rising to Group 50 for the SQ8, whilst annual tax is £475 for the first five years. Resale values are modest, retaining approximately 30% of original value after three years, though servicing costs remain reasonable for a high-tech vehicle of this calibre.

Best for: Luxury-focused buyers seeking a statement SUV with exceptional comfort, quality, and performance for long-distance travel and those wanting cutting-edge technology and design.

Not ideal for: Budget-conscious buyers, those prioritising reliability, or those needing maximum practicality (the Q7 offers more space and seven seats).


Comparison vs Key Rivals



The Verdict

You should buy the Q8 if: You prioritise luxury, style, and cutting-edge technology, seek a comfortable long-distance grand tourer, and want a statement-making SUV with exceptional cabin quality and performance.

Consider alternatives if: You're budget-conscious, prioritise reliability, need maximum practicality, or prefer the proven track records of Range Rover Sport or Mercedes-Benz GLE Class.

Competitive Position: The Audi Q8 stands as a compelling luxury SUV choice, offering distinctive styling, fabulous interior quality, and impressive performance. Whilst the Range Rover Sport and Mercedes-Benz GLE Class score higher on user ratings and overall CarGurus ratings, the Q8 delivers superior design presence and technological sophistication. The BMW X6 offers better value for money, but the Q8 remains the choice for those seeking a luxurious, comfortable, and technologically advanced grand tourer that makes a bold statement on the road.
