Released to the U.S. market for just one year, in 2003, the C5 generation RS 6 was Audi’s answer to the BMW M5, Mercedes E55 AMG, and anything else that dared challenge it. Unlike the A6 and S6, the RS 6 was the exclusive product of Quattro GmbH, Audi’s in-house performance division. Only 1,200 C5 RS 6s were imported to the U.S. market. The RS stood for RennSport or Racing Sport, and was more than just initials. The RS 6 was victorious in the SPEED World Challenge GT Series for several seasons and was an equally serious contender off the track. At its heart was a Cosworth Technology tuned 4.2-liter bi-turbo V8 engine (code named BCY) that produced 444 horsepower and an asphalt-rippling 428 foot-pounds of torque available slightly before the tach needle swept 2000 RPM. It featured aluminum construction, dual overhead cams, variable valve timing, and five valves per cylinder. A ZF five-speed automatic transmission with torque converter lockup in all forward gears was the only gearbox that could handle the power. It featured Audi Dynamic Shift Program (DSP) technology that learned your driving style if you weren’t in the mood to shift yourself through tiptronic steering wheel-mounted paddles or shifter gates. And because it was a Quattro, that power went to all four wheels in a 50/50 percent split that could be electronically proportioned up to 75 percent front or rear. Active hydro-mechanical suspension dampening called Audi Dynamic Ride Control adjusted firmness during cornering to reduce body roll, but maintained a refined ride at other times. Eight-piston, RS 6-specific brakes stopped the 4,057-pound sedan smartly, which thanks to the use of an aluminum front sub-frame was only 31 pounds heavier than the BMW M5—despite being all-wheel drive.

I am selling this 2003 Audi RS 6 on consignment for a fellow pilot and Audi enthusiast. It was originally purchased for $86,660 (in 2003 money) in Nevada and spent its first nine years there. The current owner purchased it in 2012 with 95,000 miles and it has lived in Colorado ever since. The current mileage is 177,000 miles—which would be absolutely terrifying for a C5 RS 6—except for that it comes with over nearly $30,000 of documentation in maintenance receipts of all the major items that every RS6 needs. This included rebuilding the transmission, replacement of the turbos, and routine maintenance such as the timing belt / cam timing chains, all engine seals and gaskets, oxygen sensors, EGT sensor, cooling system, engine and transmission mounts, driveshaft, CV axles, brakes, and the suspension with Bilstein shocks in place of the temperamental Dynamic Ride Control. Cosmetically it presents like a much younger, lower mileage car. The Daytona Grey over Silver leather with Carbon Fiber trim is a stunning color combination and one that looks fantastic in all lighting conditions. All paintwork is original except for the rear bumper cover and right quarter panel due. The RS 6 was the top of the market sports sedan when it was released and is still a monster today. The most important element in buying a used RS 6 is the previous owner’s care—this example has been owned by someone who could afford to maintain it correctly. As it sits, it is a perfect driver and has had all of the heavy lifting maintenance done. It represents exceptional value in the RS 6 market thanks to its ownership and documentation.

Daytona Grey over silver leather is the perfect RS 6 color combination. Daytona Grey Pearl is a dynamic metallic hue that responds dramatically to sunlight or shade. The RS 6 is a total sleeper. The only external cues to the monster performance beneath are silver sport mirrors and trim, RS 6 wheels, weaved grills, flared fenders, a rear deck lid spoiler, and twin exhausts. In an age of over-styling, the conservative and refined design language of the C5 RS 6 is refreshing. Inside, carbon fiber trim, RS 6 emblazoned logos on the seats, instrument cluster, and steering wheel under an alcantara headliner signify the RS 6’s halo model status. Tactical black gauges with of red lettering are wonderfully devoid of the information clutter found in modern cars, providing everything you need and nothing you don’t—this is a driver’s car. The center cluster continues the cockpit theme with buttons—lots of them. There are no menus to get lost in, no prolonged periods of heads down, just select your choice and get back to the task at hand—driving! Turn the key and the bi-turbo V8 comes to life in a deep rhythmic rumble. The driving theme of the RS 6 is power—lots of power. Mother of God amounts of power! Copious torque is available nearly off the line, allowing accessible delivery at all times. As the turbos spool, lag, is minimal and the power becomes exponential. It is always predictable and easily controllable thanks to the automatic torque biasing of the torsen-based Quattro all wheel drive. The C5 generation RS 6 is the sedan that can do everything. It can haul 5 adults in luxurious comfort while rewarding its driver with staggering performance.

Overall the Daytona Grey paint is in excellent condition. It does have some and mileage related imperfections, but much less than you would expect of a 170K mile car. The worst are scuffs on the front bumper cover, mild clear coat oxidation on the roof and trunk, and a few scratches on the passenger rear door. The hood is protected by clear bra in good condition. Older clear bra on the A-pillars is slightly opaque. All body panels are original with the exception of the rear bumper cover. This was replaced in April of 2015 due to a minor impact from another car. The right rear quarter panel was also repaired, but it was not replaced. No expense was spared in the repairs. I have a detailed receipt from Colorado Coach Auto Body totaling over $7,000. Neither the Carfax or Autocheck report the incident, but the receipt is included with the sale of the car. There is no rust anywhere; the RS 6 has always lived in Nevada and Colorado. All RS 6 specific trim is present. The windshield was replaced in preparation for sale and is free of any cracks or pitting. The side and rear window glass are tinted and in excellent shape. The headlight, indicator, marker, and brake light lenses are clear and crack-free. The RS 6 specific wheels have no bends, paint chips, or curb rash. They are wrapped in Nokian WR tires with over 60% tread remaining.

The interior is also in very good shape for its age. Silver leather contrasts the Daytona Grey perfectly. The matching alcantara headliner is absolutely stunning. There are no odors other than that of fine leather, and it has never been smoked in. The carpets are clean and free of rips or tears. Factory carpet RS 6 floor mats are included. Light colored leather is very susceptible to wear and tear, and the leather in this RS 6 is excellent. It is still soft and supple. There are no rips, failed stitching, or broken piping. The only imperfections are wear on the outside seatback bolsters, the driver’s being the worse. The dashboard is crack-free, but the Carbon fiber trim does have some cracks in the clear coat, the worst being on the passenger side. There are also some cracks in the carbon door trim and the center console trim. The armrest hinge is detached. The instrument cluster LCD has no failed pixels (a common issue) and all gauges and lights work correctly. There is wear on the headlight switch and HVAC button finish (a common issue). The perforated steering wheel leather is in excellent shape. All buttons and functions work correctly; the power windows, door locks, sunroof, radio, power seat adjustments, heated seats, work correctly. The heat blows warm and the air conditioning blows cold. The trunk carpet is clean. The factory jack, warning triangle, and spare tire are present. Two keys are included, as are all factory owners manuals and the original window sticker.

Both owners of this RS 6 have been meticulous stewards. It has always received regular oil changes, brake fluid flushes, coolant flushes, and gearbox oil changes. Under the first owner, the Carfax shows all regular services being completed, along with RS 6-specific routine and preventative maintenance. All work was done by Audi Las Vegas. The current owner has continued this pedigree with regular maintenance by Audi specialists Champagne Motors and Autosport Werks. In the last two years and 25,000 miles the following work has been completed:

Driver’s Side Aux Fan Brake Fluid Flush Radiator Hoses Front Axle Outer CV Boots 4 Wheel Alignment Oxygen Sensor Wiring Front Brake Rotors and Pads Front and Rear Shocks and Mounts w/ Bilstein HD Sway Bar End Links Transmission Overhaul All Engine Seals and Oil Pan Gaskets Valve Cover Gaskets Turbos Timing Belt and Cam Chains EGT Sensor All O2 Sensors Control Arm Bushings Engine and Transmission Mounts Driveshaft Rebuild Expansion Tank and Radiator

These records alone total over $24,000! All major RS 6 items, like the turbos, transmission, engine leaks, suspension, and brakes have been done. The result is a turn-key RS 6. The engine fires on command, idles smoothly, and pulls strong to redline. The transmission shifts smoothly and correctly. There are no driveline or transfer case vibrations or noises. The suspension is firm and compliant. The problematic Audi Dynamic Ride Control has been replaced with rock-solid reliable Bilstein shocks. The brakes are incredibly strong and will provide retina-separating stops if needed. The tires have lots of life left and are worn evenly.

Make no mistake, any C5 RS 6 will need continued care and maintenance, but near super car performance is the result. All of the heavy lifting for the near future has been completed on this example. You can opt for a lower mileage example with less maintenance pedigree or have the confidence that ours offers. We would like to find a buyer who appreciates this and who will enjoy the RS 6 for years and miles to come.
