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 the driver and their passengers	An Audi Q7 is the more practical, rational buy

Quick Summary

The Audi Q8 (2018-present) is a statement-making luxury SUV, designed for those who want to stand out. Its outlandish looks and significant dimensions ensure a lasting impression. Despite its sloping roofline, the Q8 offers a capacious interior with ample head and legroom in the rear, comfortably seating adults. It also provides a generous 605-litre boot, making it practical for luggage and golf clubs, though the larger Q7 offers more space and seven seats.

Engine options include 3.0-litre V6 petrol (55 TFSI), plug-in hybrid, and 3.0-litre V6 diesels (45 and 50 TDI), with a powerful 507bhp SQ8 at the top. The Q8 offers a civilised and refined driving experience thanks to its advanced air suspension, making it excellent for long journeys. The interior is a highlight, featuring deeply cushioned leather seats, premium materials like brushed aluminium, ambient lighting, and a theatrical trio of digital infotainment screens, creating a luxurious and high-tech cabin. While running costs are high, the overall experience is one of opulent performance.

Best for: Drivers looking for a statement luxury SUV, those who prioritise high-tech features and premium interior quality, and buyers seeking a comfortable and powerful long-distance grand tourer.

Not ideal for: Budget-conscious buyers due to high purchase and running costs, those needing a truly practical 7-seater, or buyers highly concerned about reliability survey performance.


Comparison vs Key Rivals



The Verdict

You should buy the Q8 if: You're looking for a statement luxury SUV, prioritising high-tech features, premium interior quality, and a comfortable, powerful long-distance grand tourer.

Consider alternatives if: You're on a strict budget, need true 7-seater practicality, or are highly concerned about reliability survey performance.

Competitive Position: The Audi Q8 (2018-present) stands out in the luxury SUV coupe segment with its bold design, opulent and high-tech interior, and powerful engine options. While it may be less practical than its Q7 sibling for larger families and comes with a higher price tag and running costs, its exceptional comfort, refined driving dynamics, and strong presence make it a compelling choice for buyers prioritising style, luxury, and a premium experience over ultimate practicality or budget constraints.
