Available for auction is this 2003 Audi C5 RS6 finished in Avus Silver over an Ebony leather interior. The RS6 was Audi’s first RS car to be sold new in the U.S. and was offered in very limited quantities. With its 40-valve twin-turbocharged V8 engine, Quattro all-wheel-drive system, and 8-piston Brembo brake calipers, the RS6 was one of the world’s most high-performance sedans upon its debut. This example boasts a long service history and a host of high-end upgrades including an Ohlins coilover suspension, MTM torque converter, a full Milltek exhaust, a REVO stage 2 performance tune, and more. Acquired by the current owner in 2014, this RS6 has since undergone a major engine-out service and is now being offered for auction out of Maryland while showing just over 94k miles on the odometer.
This example is presented in Avus Silver and features RS-specific flared wheel arches, revised front and rear fascias, a rear lip spoiler, and large dual exhaust tips. Some minor scrapes and scratches are noted throughout the exterior, and the seller reports that the front bumper was refinished in 2018 for cosmetic purposes, additional images are provided in the gallery along with a clean CARFAX report. This example is also equipped with fog lights, headlamp washers, rear parking sensors, a sunroof, upgraded LED taillights, and nano-ceramic Llumar Formula One window tint. Massive 8-piston Brembo calipers sporting “RS” logos are tucked behind 18” aluminum wheels dressed in Continental ExtremeContact DWS tires showing date codes from 2012. The seller notes that the tires will need to be replaced in the near future.
The cabin is upholstered in Ebony leather with matching door panels and carpets as well as dark burl wood trim accents throughout the dashboard, door panels, and center console. Amenities include front and rear heated seats, automatic climate control, rear window shades, upgraded LED interior lighting, and an upgraded Audi RNS-e navigation system. The seller notes sagging of the headliner towards the rear of the cabin, some fading of the digital display in the instrument cluster on hot days, and peeling on some rubberized surface coatings. There are no error codes or warning lights present, and a new face panel for the HVAC system is said to accompany the sale.
Power comes from a twin-turbocharged 4.2L V8 DOHC engine with five valves per cylinder. Output was rated at 450 HP and 415 lb.-ft of torque when new. The Quattro all-wheel-drive system is driven through a five-speed Tiptronic automatic transaxle with a Torsen center differential. This RS6 also features a number of high-end upgrades as listed below:
The CARFAX report shows service dating as far back as 2004 and the seller has compiled a comprehensive timeline of maintenance which is provided for reference in the photo gallery. The brakes have been newly replaced and a major engine-out service was completed in 2018 at 87k miles, and more recently in 2021 the engine was smoke tested for intake leaks, and an intake hose was replaced along with the intake manifold gasket, mass airflow sensor seals, connectors, and headlight washer check valve. The seller notes that the underbelly pan has been removed to begin the installation of the Sportec lower air vent mod, although this project has not been completed. All of the parts and materials will be included to finish the installation.
This sale will include a collection of spare parts and accessories, service records, owner's manuals, a set of two remote keys, a spare master key, and a clean title. Do not miss the chance to own a very well cared for and tastefully upgraded example of one of Audi’s most significant RS cars.
