Audi Sport GmbH celebrates the world debut of the new Audi RS4 Avant at the IAA 2017. It combines high performance with tremendous everyday usability. Its 2.9 TFSI engine with 331 kW (450 hp) and 600 Nm of torque makes it the sporty vanguard of the A4 family. The standard quattro drive distributes the power of the V6 biturbo to all four wheels. When creating the fourth generation of the Audi RS4 Avant, the designers took inspiration from many motorsport details of the Audi 90 quattro IMSA GTO. Massive air inlets with typical RS honeycomb structure and the wide, flat Singleframe grille define the front end. The optional Matrix LED headlights display tinted bezels. Compared to the Audi A4 Avant, the wheel arches are 30 millimeters (1.2 in) wider and are given added emphasis by the quattro blisters. At the rear end, the RS-specific diffuser insert, the oval tailpipes of the RS exhaust system and the RS roof edge spoiler make for a distinctive look. The exterior color Nogaro blue, pearl effect available optionally from Audi exclusive recalls the first generation of the high-performance Avant from 1999. The new Audi RS4 Avant travels on 19-inch forged aluminum wheels as standard; 20-inch wheels are available as an option.
