The Audi RS6 Avant GT (2025) is a limited-run special edition built on the RS6 Avant Performance, styled with visual references to the 1989 Audi 90 IMSA GTO race car. Audi built 660 examples worldwide, with 85 allocated to the US market. It uses the exact same twin-turbocharged 4.0-liter V8 tune as the RS6 Avant Performance — the GT is not a more powerful car.

What the GT adds is chassis hardware the Performance doesn't offer at any price: a standard adjustable coilover suspension, stiffer anti-roll bars, an optimized quattro sport differential, and carbon-ceramic brakes. It's also modestly lighter than the Performance, mostly from a carbon-fiber hood and front fenders, and its top-speed governor is raised well beyond the Performance's limit thanks to its wider tires and bigger front brakes.
