Expert Reviews

Impressively comfortable too
Loads of infotainment tech

Lots of expensive optional extras

Audi has made no changes to the RS Q8 for 2021.

Pros
Mega-powerful V-8 engine,
nimble chassis,
styling is more restrained than the mechanically similar Lambo Urus.

Cons
Slower and more expensive than the RS6 Avant,
brake feel isn't particularly confidence inspiring,
not quite as poised as a Porsche.

Comfortable, well-trimmed interior

Cons
Infotainment system can be distracting to use
Limited interior storage
Less practical than the related Q7
