The great thing about the 430 Scuderia—a faster, lighter, and even more compelling version of the F430—is that Ferrari didn’t have to make it. Automakers create new versions of their existing models to stimulate sales, but with North American waiting lists at two years for the F430, Ferrari didn’t need to drum up showroom traffic. Ferrari people say the primary reason for building the Scuderia is that it showcases the company’s racing technology in a street car. Another reason is that, historically, Ferrari has built more extreme versions of its entry-level sports car, going back to the F355 Challenge in 1995. And Lamborghini, its northern-Italian rival, has just introduced the Gallardo Superleggera, while Porsche, its perennial competitor, is continually making go-faster versions of the 911. Whatever the reason, enthusiasts who have well-padded bank accounts should rejoice, because the 430 Scuderia is a stunning vehicle. The engine in the F430 is a wondrous device, a snarling 4.3-liter V-8 that makes 483 horsepower. The Scuderia gets an additional 20 horsepower and an engine sound that’s so loud and enticing it causes occupants to giggle in delight. The extra power and noise come from a revised intake manifold, a freer-flowing exhaust, and a slightly higher compression ratio (up from 11.3:1 to 11.9:1), among other changes. The F1 automated manual transmission is upgraded, too, with revised software to effect neck-wrenchingly quick shifts. Ferrari says the interval has gone from 150 milliseconds on the F430 to just 60, close to the times that its Formula 1 cars were doing a couple of years ago. Like the F430, the Scuderia has an electronically actuated clutch-pack-type differential that now works in harness with Ferrari’s latest traction-control system, F1-Trac. Carbon-ceramic composite brakes are standard, with front rotors that are 15.7 inches in diameter (up 0.7 inch over the F430’s).
