Audi fans will need to have some patience, because the Audi RS5 will only arrive in the showrooms in 2010. Until then Audi will keep testing the new supercar.  Above you see a recent spy video of the Audi RS5 testing on the Nurburgring Ring.

At this early moment in time, Audi has not yet revealed specifications for the new model. However, we already know that the RS5 will be powered by the 4.2 litre V8 engine generating 450 bhp. This should allow for a 0-100 km/h acceleration of around 5 seconds and a (limited) top speed of 250 km/h.
