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 100 kg (220 lb)) and more powerful (510 PS (375 kW; 503 hp) at 8,500 rpm and 471 N⋅m (347 lb⋅ft) 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. In addition to the weight saving measures, the Scuderia's single-clutch automated manual gained improved "Superfast" software, known as "Superfast2", for faster 60 millisecond shift times. A new traction control system combined the F1-Trac traction from the 599 GTB and stability control with the E-Diff electronic differential. The Ferrari 430 Scuderia accelerates from 0-100 km/h (62 mph) in 3.6 seconds, with a top speed of 319 km/h (198 mph).
