Ferrari 458 Italia

latest masterpiece from Maranello.

 

image Ferrari has drawn from the visual spirit of the Enzo to create a power-packed replacement for the F430 that shuns the rounded curves of its past V8s in favor of chiseled, unmistakable aggression.

Boasting a new 4.5-liter V8 engine, a seven-speed dual-clutch gearbox and a 202-mph top speed, Ferrari has revealed that the car — code-named F142 and long rumored to be named the F450 — will be called the 458 Italia. Following Ferrari lore, it stands for a 4.5-liter engine with eight cylinders, though why Ferrari thought people would forget it came from Italy is anybody's guess.

Ferrari claims the engine has the highest specific output in the motoring world. It produces so much power from the all-alloy, direct-injection V8 that its specific output has smashed the old 100-hp-per-liter mark and is pushing beyond even high-output turbocharged cars.

Where Audi's twin-turbo RS6 V10 huffs and puffs its way to 114 hp per liter, Ferrari's high-compression V8 howls out 127 hp per liter.

The high-revving V8 has light internal parts and tiny piston skirts, resulting in low-rotation inertia, a 12.5:1 compression ratio and it rips out 570 hp at an astonishing 9,000 rpm.

It means that the 458 Italia will be ferociously fast, with Ferrari claiming that it will sprint to 62 mph in less than 3.5 seconds.

While advanced engine electronics are one key to the extra performance, it is also the first rear-mid-engine application of the direct-injection fuel system, which debuted on the front-mid-engine California, and it also runs Ferrari's now-traditional flat-plane crankshaft.

It will be one of the most flexible Ferraris in history, too, with 398 lb-ft of torque arriving at 6,000 rpm. While that sounds peaky, remember that it's only two-thirds of the way up the 458 Italia's rev range and that 319 of those pound-feet will be turning the ultralight flywheel from as little as 3,250 rpm.
