Ferrari F430 Challenge Stradale spy shots

[LeMansX5]

The F430 Challenge Stradale is getting ready for the streets of the world. The Challenge Stradale is Ferrari's answer to Porsche's RS-models, and both of them use almost the same recipe. While Porsche makes the RS models lighter but keeps horsepower the same, Ferrari is giving its CS not just a lighter body, but also some more power.

The standard F430 delivers 490 bhp and the Stradale is believed to have at least 520 horsepower and about 220 lbs less weight. The biggest visible change are the exhaust pipes that got moved up a bit, producing an impressive soundtrack. The microphone that is visible at the exhaust pipes in the photos is there to help Ferrari make it as loud as legal.

Due to safety regulations around the world, the door windows are not made of plastic like on the 360 CS and the wheels have 5 normal bolts instead of one centre bolt as on the Challenge cars. The inside of the doors is completely made of carbon fiber to keep the weight down. Another light weight trick is Magnesium sport wheels and the carbon grille in the back that also helps to better cool the engine. The brakes are upgraded with bigger discs, soft Pirelli tires give the car enormous grip, and the interior is completed with deep sport seats. Expect the Challenge Stradale to hit the roads in the beginning of 2007.
