A 2021 Audi RS6 Avant modified with the Legacy Edition package from ABT Sportsline has been listed for sale, offering collectors a rare opportunity to acquire one of just 200 examples of the German tuner's most comprehensive upgrade for the C8-generation super estate.
The car is finished in Nardo Gray over black leather upholstery with red stitching and has covered 14,000 miles from new, all under the current owner. It is offered with an ABT certificate, a window sticker, an owner's manual, two keys, service records, a clean Carfax report, and a clean Arizona title.
ABT's Legacy Edition treatment extends well beyond cosmetic tweaks. The twin-turbocharged 4.0-litre V8, which features a 48-volt mild-hybrid system and cylinder deactivation, has been fitted with an ABT tune and exhaust system, lifting output to 690 horsepower and 649 lb-ft of torque. Power is sent through an eight-speed Tiptronic automatic transaxle and Quattro all-wheel drive with a sport rear differential.
The chassis has been similarly reworked. ABT height-adjustable springs join the factory RS-tuned adaptive air suspension, all-wheel steering, and cross-drilled ventilated disc brakes. The car rides on 22-inch ABT forged wheels wrapped in Pirelli P Zero tyres.
Visually, the Legacy Edition is distinguished by a suite of carbon-fibre aero components, including a hood insert, front lip, rear diffuser, rear spoiler, mirror caps, and side skirts, along with trim pieces for the grille and tailgate. The front lip and rear diffuser carry RS6-LE logos, while fender inserts denote the car as 1 of 200.
Inside, ABT has added headrest embroidery, Dinamica seat inserts with RS6-LE logos, 1 of 200 door sill plates, RS6-LE floor mats, and Dinamica trim over the gear selector, seat bases, and entryways. The steering wheel and paddle shifters have been retrimmed in Dinamica with red stitching.
Factory equipment includes Matrix-Design LED headlights with Audi laser light and high beam assist, a panoramic roof, parking sensors, LED taillights, and a power-operated liftgate. The cabin features heated and ventilated front RS sport seats, a Bang & Olufsen 3D sound system, Audi MMI Touch infotainment with Navigation Plus, Audi Advanced Key keyless entry, an Audi Phone Box wireless charger, and four-zone automatic climate control. The Driver Assistance Package added adaptive cruise control and Audi Side Assist.
The Audi Virtual Cockpit Plus 12.3-inch digital instrument cluster incorporates a digital speedometer, tachometer, and supplementary gauges, with additional display views for tyre pressure, torque, boost pressure, lap times, and G-force.
Service records show cooling system repairs carried out by Audi North Scottsdale in May 2025, with the most recent oil change performed in December 2025. The Carfax report is free of accidents or other reported damage.
The RS6 Avant has long served as the benchmark fast estate, combining supercar performance with everyday practicality. ABT Sportsline, based in Kempten, Germany, has tuned Audi models for decades and is regarded as one of the marque's most closely affiliated specialists. The Legacy Edition represents one of its most complete packages for the C8 RS6, and with production capped at 200 cars, examples rarely come to market.
For buyers seeking a turnkey modern performance estate with factory-backed tuning credibility and documented history, this example presents a compelling proposition. The listing includes the ABT Legacy Edition certificate that confirms its provenance.
