Audi reserves the RS badge for its highest-performance vehicles, and the RS Q8 is the ultimate version of its top SUV model, the Q8. While it has a 4.0-liter twin-turbocharged V-8 engine like the lesser SQ8, the RS Q8 differentiates itself with a whopping 591 horsepower and an aggressive appearance that gives it lots of presence on the road.
Performance is blistering and nearly as impressive as the RS Q8’s significantly more expensive sibling, the Lamborghini Urus, with which it shares many components under the skin. The interior features the same tech-forward layout as other Q8 models; ritzy materials such as supple leather and faux suede abound. With a price well above $100,000, the RS Q8 isn’t cheap but as a luxury-performance SUV that does it all, it lives up to its heady cost.
