Today is Power Convertible Day at the Nürburgring. Earlier, we introduced spy shots of the upcoming Lexus IS-F Convertible, and now we have another set of photos, this time of the Audi RS5 Convertible during its own testing on the 'Ring.

The strange thing is that - unlike the previous prototypes caught testing - this vehicle is wearing heavy camouflage leading us to believe that there will be some minor tweaks on the exterior which Audi->ke14 wants to keep a secret.

Just like the coupe version, the RS5 Convertible will be powered by a 4.2 liter V8 engine delivering a total of 450 HP at 8,250 rpm and a peak torque of 317.15 lb-ft available between 4,000 and 6,000 rpm. The sprint from 0 to 60 mph will be made in 4.7 - 4.8 seconds - because the convertible version will be bit heavier when compared to the coupe, but top speed will still come limited to 155 mph.

Expect to see the new Audi RS5 Convertible launched by the end of the year.
