Ferrari has confirmed that the car, codenamed F142 and long rumoured to be named the F450, will be called the 458 Italia. The name derives from the powerplant: a 4.5-litre V8 which Ferrari claims has the highest specific output of any normally aspirated car engine.
It certainly has more in common with superbikes than cars; at 127bhp per litre, the specific output is greater than that of many turbocharged engines.
The high-revving 4498cc V8 has very light internal parts and tiny piston skirts, resulting in low rotation inertia and a 12.5:1 compression ratio. It puts out 562bhp at 9000rpm, 500rpm higher than the 430. That makes it the highest-revving Ferrari road car ever.
It means the 458 Italia will be ferociously fast, and Ferrari claims it will sprint to 62mph in under 3.4sec on its way to a top speed of “over 200mph”. The 458 has lapped the Fiorano test track in 1m 25s, a fraction off the time of the Enzo hypercar.” - Autocar |
