The 4.3-liter V8 engine packs in a 112 horsepower per liter-that's 483 total. It's just one of the Formula One-derived innovations in the beautiful Ferrari F430 and its convertible sister, the F430 Spider [shown]. There's also the sequential manual gearbox that shifts in only 150 milliseconds, providing practically uninterrupted acceleration, and a steering-wheel-mounted rotary switch that instantly adjusts driving dynamics to match the desired performance. The industry-first electronic differential manages huge torque loads under high-G cornering to eliminate wheel spin in the turns.
