The multi-award-winning 458 Italia


The Ferrari 458 Italia continues to go from strength to strength and has garnered over 30 international awards in its short career. Yesterday, it added two further plaudits to that collection at the International Engine of the Year Awards when its V8 was voted “Best Performance Engine” and “Best Engine Above 4 Litres”.

 

The success being enjoyed by the 458 Italia with both critics and public alike crosses all borders– it has won awards in a host of different nations from the USA to the Far East and Europe. In the US, the mid-rear V8 was named "World Performance Car of the Year". It was also named “Car of the Year” by the Robb Report.

Maranello, 19th May - The Ferrari 458 Italia continues to go from strength to strength and has garnered over 30 international awards in its short career. Yesterday, it added two further plaudits to that collection at the International Engine of the Year Awards when its V8 was voted “Best Performance Engine” and “Best Engine Above 4 Litres”.


The success being enjoyed by the 458 Italia with both critics and public alike crosses all borders– it has won awards in a host of different nations from the USA to the Far East and Europe. In the US, the mid-rear V8 was named "World Performance Car of the Year". It was also named “Car of the Year” by the Robb Report and topped the New York Times rankings.


On the other side of the Atlantic, the discerning British motoring media proved equally enthusiastic. In fact, the 458 Italia scooped both BBC Top Gear Magazine’s “Supercar of the Year” and “Car of the Year Awards”. Staying in Britain, CAR magazine also named the 458 Italia “Performance Car of the Year 2010”, as did Auto Express and What Car. It triumphed too as the Daily Telegraph’s “Car of the Year” and TV programme Fifth Gear’s “Fast Car of the Year”. The 458 Italia also enjoyed an enthusiastic welcome from the German and Italian public with the result that it voted “Sports Car of the Year” by the highly reputable Auto Moto und Sport and Quattroruote magazines.


Continuing around the world, the authoritative Car Middle East magazine declared the 458 Italia both “Car of the Year” and “Supercar of the Year” also. In China, Top Gear, Auto Moto und Sport, Robb Report and the popular X-Car website all named it “Car of the Year”.


Lastly, in Japan, the 458 Italia was Engine’s "Best Car of the Year", proving that the Ferrari’s extreme sportiness has a genuinely worldwide appeal.



 
 

The engine is a dry-sump 90 degree V8 with a displacement of 4499 cc and is mid-rear mounted. It is an entirely new design engineered to reach a maximum of 9,000 rpm – a first on a road car – with a high 12.5:1 compression ratio and maximum power output of 570 CV. This equates to an outstanding power output of 127 CV/litre, a new benchmark for a naturally-aspirated production engine.


The generous torque available - 540 Nm at 6000 rpm, with over 80 per cent available from 3250 rpm – ensures rapid pick-up from all revs. The specific torque output of 120 Nm/l is another record.


The design of the engine components has been influenced by the carry-over of racing technology – F1 in particular – for maximum fluid-dynamic efficiency in order to achieve both performance and fuel consumption objectives, and meet the most stringent international emissions restrictions. The piston compression height was reduced as per racing engine practice. Similarly, thinner compression rings have been adopted to minimise friction between piston and liner. A graphite coating was applied to the piston skirt for the same reason.


To help further reduce internal friction, the cylinder block has four scavenge pumps. Two pick up oil from the cylinder heads and front and rear of the engine via dedicated oil recovery ducts outside the crankcase area, and two pick up oil from below the crank throws. The recovery ducts of the latter are interconnected in two groups of four cylinders to optimise the scavenge function and create a strong vacuum (800 mbar) around the crankshaft. This solution prevents excess oil splashing out of the sump and onto the rotating crankshaft and thus reduces power loss caused by friction. It also reduces losses due to windage caused by the pumping action of the pistons.


The engine oil pressure pump features variable displacement geometry which reduces the amount of power absorbed at high revs. Lowering the pump’s displacement actually increases the power available at the crankshaft for the same amount of fuel used.


As is traditional for Ferrari engines, the new V8 is equipped with continuously variable timing on both inlet and exhaust cams. The aluminium intake manifold has been lightened by reducing the wall thickness. It has short, almost straight inlet tracts to reduce losses and a system that varies the geometry of the manifold, optimising the volumetric efficiency throughout the rev range. This is achieved by incorporating three pneumatic throttle valves in the central section between the two plenums. The engine mapping provides four different configurations of the valves for optimum torque values at all revs.


The use of GDI with Split Injection improves engine performance by modulating the injection in two phases, increasing combustion efficiency and the torque at low revs (by up to 5 per cent). A high injection pressure (200 bar) guarantees adequate pulverisation of the petrol and an optimal air/fuel mix right up to 9000 rpm. This feature again results in better performance and lower fuel consumption. The exhaust system was designed to provide the kind of thrilling soundtrack owners of Ferrari’s V8s are used to whilst also guaranteeing high levels of acoustic comfort. One of the main objectives with the exhaust was to reduce weight. The catalytic converter is attached to the central section of the exhaust by a flexible element to reduce the amount of vibration transmitted and to thus allow thinner metal to be used. Similarly the pre-catalytic converter has been eliminated, lowering overall weight and reducing back pressure whilst still respecting strict Euro 5 and LEV2 emissions.
