Fresh off its record-breaking run at the famous Nürburgring, Audi has announced that the recently-revealed RS Q8 high-performance SUV is coming to the US. Audi left nothing to other luxury SUV makers, giving the RS Q8 the same 4-liter twin-turbo from the RS6 Avant and RS7 Sportback, and makes 591 horsepower and 590 ft-lb of torque in its European specification. Audi claims a 0-60 time of just 3.8 seconds, thanks to an eight-speed automatic and Quattro all-wheel-drive and the requisite computer aids. Top speed is limited to 155 MPH unless you spring for the optional dynamic package, where it soars to nearly 190 MPH. The RS Q8 also packs a 48-volt lithium-ion mild-hybrid system that combines with cylinder deactivation to maximize fuel economy. The exterior features extended wheel arches that increase the width by 0.4 inches front and 0.2 inches rear, and 22-inch 10-spoke aluminum wheels are standard. Audi's MMI dual-touchscreen setup dominates the dashboard, and the Nappa leather and Alcantara seats feature embossed RS logos. The RS Q8 should be available in the US by mid-2020.
