Audi, A6, C5, RS6 Quattro (2002-)

The Audi A6 C5 RS6 Quattro was a high-performance variant of the A6 line produced from 2002 to 2004. It featured a significant redesign and upgrade over its predecessor, incorporating advanced technology and engineering.

Engine:

• The RS6 was powered by a twin-turbocharged V8 engine, known as the 4.2 FSI (Fuel Stratified Injection).
• This powerful mill produced an impressive 444 horsepower at 5,500 rpm and 400 lb-ft of torque at 3,000 rpm.
• The turbochargers were driven by a modified version of Audi's Torsen-based Quattro system, which provided efficient power delivery.

Transmission:

• The RS6 was equipped with a 6-speed Tiptronic automatic transmission, featuring manual and semi-automatic modes for enhanced driver engagement.
• A shorter final drive ratio (3.15) improved acceleration and responsiveness.

Suspension and Chassis:

• Audi employed a modified version of the C5's multi-link suspension design, using stiffer springs and revised dampers to improve ride quality and handling.
• The front axle used MacPherson struts with gas-filled shocks, while the rear featured a double wishbone arrangement with coil springs and monotube dampers.

Brakes:

• The RS6 came equipped with massive 13.8-inch (350mm) Brembo ventilated disc brakes at the front and 12.2-inch (310mm) units at the rear.
• The rotors were made from a two-piece design, allowing for increased cooling efficiency and reduced thermal stress.

Interior and Exterior:

• The C5 RS6 interior featured exclusive trim pieces and styling cues, including quilted leather upholstery, Alcantara headliner, and carbon fiber accents.
• Audi's renowned Quattro system was also visually represented through the use of a red "Q" badge on the vehicle's exterior.

Performance Capabilities:

• The RS6 accelerated from 0-60 mph in just 4.8 seconds, with a claimed top speed of 155 mph (electronically limited).
• Audi engineers aimed to provide exceptional handling and stability through an integrated setup combining chassis tuning, electronics, and aerodynamics.

Production Numbers:

• Approximately 13,000 RS6 units were produced worldwide between 2002 and 2004.
• The model's exclusivity was further underscored by its high price point and selective distribution network.
