Ferrari 458 Italia Engine and Performance
With the arrival of the 458 Italia, the current Ferrari range now includes two very different 8-cylinder models, each one linked to separate traditions with deep roots into the Ferrari history. While the California is a top performance car which lends to a versatile and daily use, the 458 Italia continues the Ferrari tradition of extreme vehicles redefining, at the same time, the sport car driving.
Ferrari 458 Italia engine is a 90 degree V8 with 4,499 cm3 displacement mounted in the mid-rear position. It delivers a maximum of 9,000 rpm which represents an unprecedented achievement in the road cars segment; compression ratio is 12:5:1 and 570 hp is the maximum power output. 458 Italia's performances provide extreme sportiness, great fun and superb driving pleasure. Other distinctive structural features include the car dry sump lubrication and flat-plane crankshaft with a 180° angle between throws. Dry sump lubrication systems use hydraulic pumps to draw the oil out of a separate oil reservoir and then spray it to the various engine components, bearing, pistons and gears at high pressure. When the oil runs back into the sump, it is pumped back to the oil tank by a scavenge pump via dedicated oil recovery ducts. This solution prevents excess oil splashing out of the sump and onto the rotating crankshaft reducing power loss caused by friction. The flat crankshaft with a 180° between its throws is typical of racing car engineering. It has long been adopted by Ferrari because of its lower mass and inertia as well as the even firing order between banks allowing an optimal exhaust manifold design.
The use of radically innovative machining and engine component manufacturing processes has resulted in a specific power output of 127hp/l, which is another record achievement for a car of this kind. At both high and medium revs, the 458 Italia's torque figures exceed those of the F430 by up 20 per cent.
The car's excellent performance is reflected in rapid pick-up at all revs, thanks to a maximum torque of 540 Nm at 6,000 rpm, of which 80 per cent is already available at 3,250 rpm. The engine continues to punch power until it reaches maximum revs, which is why the 458 Italia is such a pleasure and thrill to drive. Integrated design between each individual component and the carry-over of technologies from Formula One were central to the Ferrari 458 Italia's development.
