The 458 Speciale was unveiled in 2013 at the Frankfurt Motor Show[19][20] as the high performance variant of the 458 Italia. Distinctions of the Speciale over the standard 458 Italia are the forged wheels, vented bonnet, finned side sills, a taller rear spoiler and redesigned bumpers, which include active aerodynamics designed by Ferrari Styling Centre in cooperation with Pininfarina; front and rear movable flaps balance downforce and cut drag at speed. The engine was revised, with power increased to 605 PS (445 kW; 597 hp) at 9,000 rpm and 540 N⋅m (398 lb⋅ft) of torque at 6,000 rpm.[21] Electronic systems were updated too and side slip angle control (SSC) was introduced to improve car control on the limit. SSC performs instant-to-instant analysis of the car’s side-slip, comparing it with the target value and then optimising both torque management (via integration with F1-Trac traction control) and torque distribution between the two wheels (via integration with the E-Diff electronic differential]). The Speciale accelerates from 0 to 100 km/h (62 mph) in 3.0 seconds (0–200 km/h (120 mph) in 9.1 seconds).[22][23] Ferrari declared a Fiorano test track lap time of 1:23.5, only 0.5 seconds slower than the F12 berlinetta. Lateral acceleration now reaches 1.33 g. This fantastic example has covered just 862 miles from new.
