Serving as the successor to the 360 Challenge Stradale, the 430 Scuderia ("scuderia" meaning "stable", but also used in the context of motor racing teams, including Ferrari's own) was unveiled by Michael Schumacher at the 2007 Frankfurt Auto Show. Aimed to compete with cars like the Porsche 911 GT3 RS and the Lamborghini Gallardo Superleggera ("superleggera" meaning super light weight), it is lighter (by ) and more powerful ( at 8,500 rpm and of torque at 5,250 rpm) than the standard F430. Increased power comes from a revised intake, exhaust, and an ion-sensing knock-detection system that allows for a higher compression ratio in the engine. Thus the weight-to-power ratio is reduced from 2.96 kg/hp to 2.5 kg/hp.
