2003 Audi C5 RS6
The 2003 Audi C5 RS6 is a high-performance version of Audi's C5-generation A6, produced by its high-performance subsidiary company, Audi Sport GmbH (formerly known as quattro GmbH). The "RS" in RS6 stands for "RennSport," which translates from German to "Racing Sport."
Following the success of the previous RS2 and the first RS4, Audi introduced the first RS6 model in 2002 as a 2003 model year. The C5 RS6 was available in two body styles: 4-door sedan and 5-door Avant (wagon).
The 2003 Audi C5 RS6 was powered by a 4.2-liter V8 engine with two turbochargers, producing 444 horsepower (450 PS) and 428 lb-ft of torque. The engine was paired with a 5-speed Tiptronic automatic transmission that delivered power to all four wheels through Audi's renowned quattro all-wheel-drive system.
Performance-wise, the RS6 was capable of accelerating from 0 to 60 mph in just 4.6 seconds, with an electronically limited top speed of 155 mph. However, with the limiter removed, it was capable of reaching over 170 mph.
The RS6 differentiated itself from the regular A6 with unique bodywork, including larger air intakes, flared wheel arches, larger wheels, and dual exhaust pipes. Inside, it offered sport seats, a sport steering wheel, and RS6 badging, while still maintaining the luxury amenities and build quality expected from an Audi.
The RS6 was equipped with Dynamic Ride Control (DRC), a system which used diagonal linked shock absorbers to counteract roll and pitch. It also came with large brakes, specifically eight-piston calipers with 365mm discs at the front.
Despite being a high-performance vehicle, the RS6 was also a practical daily driver, especially the Avant variant, offering ample cargo space along with its impressive performance credentials.
The C5 RS6 was produced until 2004, and it was succeeded by the C6 RS6 in 2008. Although the C5 RS6 was never officially sold in North America, it has become a sought-after model among car enthusiasts for its blend of performance, luxury, and practicality.
