The 2021 RS6 Avant starts with a price tag of $110,045 and is the first RS wagon that Audi has ever sold in America. It has a 591-hp twin-turbocharged 4.0-litre V-8 engine and all-wheel drive, making it a worthy competitor for Mercedes-AMG’s own high-performance wagon, the E63. Now that the cars are arriving in greater numbers, more news should be coming forward.
