Sharing the same 4.2 FSI V8 engine and seven-speed S tronic transmission as its RS 5 Coupe counterpart, the Cabriolet has 331 kW (450 hp) and 430 Nm (317 lb/ft) of torque at its disposal, meaning 100 km/h appears in 4.9 seconds. Top speed is electronically limited to 250 km/h (155 mph), but Audi will raise this to 280 km/h (174 mph) upon request.
Available with the same equipment as the Coupe version, such as drive select; a feature that allows the driver to tailor the steering system, S tronic, throttle valves and exhaust sound flaps to suit their tastes, the MMI navigation plus system with seven-inch colour screen and DVD drive, and Audi connect with integrated WLAN hotspot which can be customized to include Audi traffic information with Google Earth images and Street View.
The lightweight fabric roof, which is lined with a special heat and noise insulating foam layer, can be opened and closed at the touch of a button in 15 seconds and 17 seconds respectively – even while travelling at speeds of up to 50 km/h (31 mph). When opened, the roof mechanism takes up just 60 litres of volume from the Cabriolet’s 380 litre luggage compartment.
Visually, everything else is standard RS 5 fare, including those bulging wheel arches, ten-spoke 9 x 19-inch alloy wheels (20-inch options), imposing hexagonal single-frame grille, aggressive fascia with large air intakes, wedge-shaped xenon plus lamps with LED strips, rear diffuser and large oval tailpipes. Exterior finishes will include one monochrome colour, four metallic and pearl effect colours and three crystal effect paints, with roof sections in either black, brown, grey or red.
