As a previous B5 RS4 owner I was left somewhat disappointed with the removal of the trademark forced induction from the 420ps B7 RS4, Now the 2013 Audi RS4 has shown its in production prototype on Germany’s Nürburgring.
The B8 Audi RS4 is incorporating a much more aggressive front fascia complete with lower and wider air intakes similar to the RS5 Coupe.
Rumors have suggested that an all-new 4.0-liter twin-turbo V8 could be put to use here and with the extensive competition from AMG and BMW M-Power it is looking likely.
BMW have released another teaser video of the 2012 M5 undergoing high speed testing at the Nardò proving grounds in Italy.
These cars are now a production version of the M5 concept coming close to final form, a electronically dampening suspension and a twin-turbo 4.4-liter V8 with approximately 570 BHP and 720 Nm of torque.
Taking all this power to the rear wheels will be a seven-speed dual-clutch transmission and rumour has it an all-wheel drive could eventually be offered.
The car is expected to be shown at the Frankfurt Motor Show, but the video hints that it may show off production ready vcarinets off at M-Power in June.
