1999 Audi RS4

Audi RS4

Audi introduced the first generation RS4 in 2000 as the successor to the fabled Porsche developed/RS2. The vehicle, like its predecessor, was available only as an Estate/Avant (station wagon), and was built on an existing platform, in this case the "B5" generation A4/S4. Base price was around 103,584 Deutsche Mark, and was not available for sale in the United States of America. The RS4 was available for sale in most of Europe and in some Latin American countries, including Mexico and Brazil.

Power came from a modified version of the B5 S4's 2.7 L, twin-turbocharged V6 engine tuned by Cosworth Technology, featuring enlarged intake/exhaust ports on the cylinder heads, turbochargers and intercoolers, new induction and exhaust systems and a re-calibrated engine management system; a six-speed manual transmission and Audi's Quattro all wheel drive system were part of the package. The modifications were enough to bump the engine's power output from the 265 PS (195 kW/261 hp) and 350 Nm (257 ft·lbf) of the S4 to 380 PS (280 kW/375 hp) and 440 Nm (325 ft·lbf).Even with a curb weight of 1620 kg (3568 lb), the RS4's powerful engine gave it the performance of a sports car.

The 100 km/h (62 mph) mark could be reached in only 4.7 seconds and the 160 km/h (100 mph) could be achieved in just 11.6. Brakes were also developed in house by Audi/Cosworth Technologies not by Porsche as with the RS2. It now has 360 mm (14.2 inches) rotors at the front and 312 mm (12.2 inches) at the rear gave the RS4 braking to match, needing less than 50 m (155 ft) to come to a full stop from a speed of 110 km/h (69 mph).RS4 production stopped in 2001, although the last several units sold were registered as 2002 models.
