Rumoured to debut at the Frankfurt Motor Show in September, the B9, as pictured, will not only feature the now trademark RS4 flared wheel arches and usual RS exterior updates, but herald the return of a sedan compared to the Avant only B8.
Unlike its predecessor and the much loved B7 RS4 though, the B9 will reportedly drop the normally aspirated 4.2-litre FSI V8 for the same 2.9-litre twin-turbo V6 used in the new Porsche Panamera 4S, although expect power to match the bent-eight's 331kW/430Nm. Top speed will again be limited to 250 km/h or 280 km/h with the dash to 100 km/h from standstill said to be over in just under four seconds.
More details will become known in the coming months leading up to Frankfurt.
