Ferrari F430 Challenge Stradale was spied in Europe during off-road testing on a gravel road.
The Ferrari F430 Challenge Stradale is answer to Porsche’s RS-models. The standard F430 delivers 490 bhp and the Stradale is believed to have at least 520 bhp and to weigh about 220 pounds less. The biggest visible changes are the exhaust pipes that are moved up a bit. Due to safety regulations around the world, the door windows are not made of plastic anymore like on the 360 CS and the wheels have 5 normal bolts instead of one center bolt like on the Challenge cars.
