Ferrari is preparing the launch of the super sports car F 430 Challenge Stradale at the Paris Motor Show coming fall. The car is set to rival Porsche’s upcoming GT3 RS, which is equally due for launch this year. The Stradale is about 220lbs lighter than the standard F 430. While the latter is powered by a 4.3 litre V8 engine producing 490 HP, the light weight Stradale‘s performance is said to rate around 520 HP with the same engine.

The photos are showing a prototype during road testing in Maranello. The pictured test car still has some tape at the front end for disguise. At the rear end clearly visible, the exhaust pipes are located further up in the middle and not on the side like in the F 430.
