The Ferrari 360 is a mi-engine two-seat sports car produced between 1999 and 2005. The 360 replaced the Ferrari F355 and was itself replaced by the fairly similar Ferrari F430. For the 360, Ferrari partnered with Alcoa to produce an entirely new all-aluminum space-frame chassis that was 40% stiffer than the 355, yet 28% lighter despite a 10% increase in overall dimensions. Along with the new frame was a new Pininfarina body styling that broke ranks with the last decade's sharp angles and flip-up headlights, replacing them with a rounded appearance that harkened to the 1960s. The new V8 engine, common to all versions, was only slightly larger and more powerful than the 355's at 3.6 litres and 300 kW (400 bhp) of power, but the lighter frame and added stiffness improved performance; the 0 to 100 km/h acceleration performance improved from 4.6 to 4.4 seconds (not as trivial as it might seem), and in the Challenge versions it was as low as 4.0 s. An engine replacement resulted in the current V8 road model, the F430 (internally referred to as the evoluzione or evo) which came out in 2004.
