Impressively comfortable too

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.

By: 
caranddriver.com

The RS Q8 is unchanged for 2021.

Pros
Turbo V8 delivers devastating straight-line performance
Nimble, lively handling puts most sports cars to shame
Comfortable, well-trimmed interior

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