The Audi A4 Avant 2.7 V6 Quattro RS4 belongs to the first generation of the RS4 Avant, known internally as the B5 RS4 Avant. This model was developed by Audi Sport as the successor to the RS2 Avant and was introduced in the late 1990s as a performance-oriented version of the A4 Avant. It was based on the A4/B5, but the body, powertrain, and suspension tuning were significantly modified. The RS4 Avant 2.7 V6 Quattro marks the beginning of Audi’s modern RS line, combining a practical body style with advanced technology for its segment at the time.
This version features a 2.7 V6 Biturbo engine developed in collaboration with Cosworth, which supported the engine management system and performance components. The engine is known for rapid torque build-up and immediate responsiveness. Paired with permanent quattro all-wheel drive and a six-speed manual transmission, it offered a fast, practical, and technically advanced station wagon. Production of the B5 RS4 Avant was limited, giving it a unique place in Audi’s history.
The market position of the RS4 Avant 2.7 V6 Quattro was that of a niche model for enthusiasts of powerful wagons. It emphasizes dynamic performance without sacrificing the practicality of the A4 Avant. Its compact body, wide suspension, and all-wheel drive make it a benchmark in the fast family car segment.
This Audi RS4 Avant is equipped with a 2.7 V6 Biturbo engine producing 380 horsepower and 440 Nm of torque. It features quattro all-wheel drive, a six-speed manual transmission, 18-inch RS4 alloy wheels, xenon headlights, climate control, sport seats, and a sport interior with RS accents. The sport exhaust system, with stainless steel manifolds and a heat shield, enhances its performance character.
The braking system includes Cosworth brakes measuring 360 mm in the front and 312 mm in the rear. The engine has been tuned by Cosworth, consistent with the model’s development history. Prior to sale, the vehicle underwent a comprehensive service, including replacement of the timing belt, tensioner, idler pulley, alternator, multi-ribbed belt, gaskets, oil and coolant hoses, oil/water cooler, and front and rear brake rotors and pads.
This early RS4 Avant features a 2.7 V6 Biturbo engine, quattro all-wheel drive, a six-speed manual transmission, and Cosworth upgrades. The documented work and technical enhancements make this a notable example within the RS4 Avant series. Viewing is recommended to appreciate its condition.
