Ferrari 458 Italia
Continuing the stepwise evolution of Ferrari’s mid-engine supercar, the 458 introduces several key features into the model range including a 570 bhp direct injection engine and a dual-clutch 7-speed transmission. Furthermore, the shape of the car has been heavily reworked by Pininfarina including an elegant new interior.
Many of the new elements of the 458’s body are dictated by aerodynamics. This is particularly true of the front grill which has aeroelastic winglets that bend at speed to increase airflow under the car. This eventually reaches the rear diffuser which can produce 794 lbs of downforce at top speed split 41/59% over the wheels. Air apertures in the C-pillar direct air towards the engine and vents above the rear diffuser help the twin transmission radiators cool. The final element is a small intake and exit that are located around the front headlights to reduce drag.
The car’s name comes from its 4.5-liter, 8-cylinder engine which is “the highest-revving street-legal production V-8”². It’s notable for it’s direct 2900 psi gasoline injection capable 570 bhp at speed and 565 on the dyno. “Further to its credit, this new 4.5-liter V-8 is not only more flexible and powerful than the 4.3-liter engine it replaces, it also consumes 13 percent less fuel, according to Ferrari.”³
The all-aluminum F136-FB V8 uses a variable intake manifold with three pneumatic throttle valves to control air flow. Furthermore the vales are fully variable on both the intake and exhaust. It has a complex dry-sump lubrication system that uses a 5 variable pumps and scavenge which is also designed to create a “partial vacuum around the ﬂat-plane crankshaft, which is said to improve torque by 6 lb.-ft. at 2500 rpm.”¹
The only available transmission in the 458 is a 7-Speed unit that uses a dual clutch system. The system is from Getrag. The system can change gears in 0.04 seconds.
Like the 430, the Italia is full of electronic systems which manage the performance potential of the car. Central to these systems is a manettino knob which can control the multiple embedded systems in the 458 for one of five preset modes. This includes the E-Diff 3 active differential, traction control, stability control, ABS, Magnetorheological Dampers and transmission.
Since, “the Italia laps Fiorano as quickly as the
Enzo and the 430 Scuderia”¹, it’s a rational answer to Ferrari’s increasing performance pedigree. The car is slightly larger and heavier than the outgoing 430, but it’s new engine and rigid chassis make up for the difference.
Maranello, July 28th 2009 – While it’s true that every Ferrari is innovative by definition, it’s equally true that in the course of the Prancing Horse’s history, certain cars have marked a genuine departure from the current range. This is very much the case with the Ferrari 458 Italia, which is a massive leap forward from the company’s previous mid-rear engined sports cars.
The new model is a synthesis of style, creative flair, passion and cutting-edge technology, characteristics for which Italy as a nation is well-known. For this reason Ferrari chose to add the name of its homeland to the traditional figure representing the displacement and number of cylinders.
The Ferrari 458 Italia is a completely new car from every point of view: engine, design, aerodynamics, handling, instrumentation and ergonomics, just to name a few.
A two-seater berlinetta, the Ferrari 458 Italia, as is now traditional for all Ferrari’s road-going cars, benefits hugely from the company’s Formula 1 experience. This is particularly evident in the speed and precision with which the car responds to driver inputs and in the attention focused on reducing internal friction in the engine for lower fuel consumption than the F430, despite the fact that both overall displacement and power have increased. However, Ferrari’s track experience makes its presence felt in the 458 Italia not only in terms of pure technological transfer but also on a more emotional level, because of the strong emphasis on creating an almost symbiotic relationship between driver and car. The 458 Italia features an innovative driving environment with a new kind of steering wheel and dashboard that is the direct result of racing practice. Once again input from Michael Schumacher – who was involved from the very start of the 458 Italia project – played an invaluable part.
The Ferrari 458 Italia’s Pininfarina design provides further evidence of the complete departure from the past that this new car hails. The Ferrari 458 Italia has a compact, aerodynamic shape, underscoring the concepts of simplicity, efficiency and lightness that inspired the project. As with every Ferrari, the car’s styling has been very heavily influenced by the requirements for aerodynamic efficiency, as can be seen from the downforce of 140 kg at 200km/h generated by the new model. The front features a single opening for the front grille and side air intakes, with aerodynamic sections and profiles designed to direct air to the coolant radiators and the new flat underbody. The nose also sports small aeroelastic winglets which generate downforce and, as speed rises, deform to reduce the section of the radiator inlets and cut drag.
The new 4499 cc V8 is the first Ferrari direct injection engine to be mid-rear mounted. It has a very low piston compression height typical of racing engines which contributed to achieving its compression ratio of 12.5:1. Equipped with the traditional flat-plane crankshaft, the engine delivers 570 CV at 9000 rpm and, with an outstanding power output of 127 CV/litre, sets a new benchmark not only for the whole Ferrari range and the history of company, but also for the entire market segment. Maximum torque is 540 Nm at 6000 rpm, over 80 per cent of which is available from 3250 rpm. Specific torque is a record 120 Nm/litre. However, what is truly extraordinary is the amount of torque available while still maintaining high levels of power at low revs.
The car’s soundtrack is also typical Ferrari, with an exciting, powerful growl emerging from the engine before it channels through to the exhaust’s three rear tailpipes.
The 458 Italia is equipped with the seven-speed dual-clutch transmission which increases performance whilst providing very smooth shifts even at full throttle. The engineers have developed specific, sportier gear ratios to match the power and torque curves of the new V8, guaranteeing high torque even at lower engine speeds and allowing the car to reach its maximum speed in top gear.
This new Ferrari is also a major leap forward when it comes to cutting emissions. Despite the fact that the new engine is significantly more powerful than the V8s that preceded it, the Ferrari 458 Italia produces just 320 g/km of CO2 and fuel consumption is 13.7 l/100 km (combined cycle), the best in the entire segment.
The engineers also focused on weight reduction during the design phase for similar reasons. Consequently, the Ferrari 458 Italia has a dry weight of 1380 kg with a power-to-weight ratio of 2.42 kg/CV. Weight distribution is also optimal with 58 per cent over the rear axle. The result of the engineers’ endeavours can be summed up in to two simple statistics which together perfectly encapsulate the Ferrari 458 Italia’s exceptional performance: 0-100 km/h acceleration in under 3.4 seconds and a maximum speed in excess of 325 km/h.
For the new chassis, once more in aluminium, Maranello’s engineers incorporated various types of advanced alloys along with aerospace industry-derived manufacturing and bonding techniques.
With regard to vehicle dynamics, the Ferrari 458 Italia’s suspension features twin wishbones at the front and a multi-link set-up at the rear tuned for maximum roadholding and superlative handling. Along with a more direct steering ratio, the 458 Italia thus offers extremely rapid turn-in and body control whilst maintaining superior ride comfort.
The integration of the E-Diff and F1-Trac (now controlled by the same ECU) and their respective mappings is even greater, resulting in a 32 per cent increase in longitudinal acceleration out of corners compared to previous models. The evolution of the control logic, with even faster and more accurate calculation of levels of grip, ensures even greater roadholding, better handling and ease of control on the limit.
The same ECU also governs the high-performance ABS, providing even more precise control over the logic threshold and greater efficiency. The brakes also feature a prefill function whereby the pistons in the callipers move the pads into contact with the discs on lift off to minimise delay in the brakes being applied. This combined with the ABS has cut the 100-0 km/h braking distance to a mere 32.5 metres.
The Ferrari 458 Italia’s interior is another area of the car that exalts its sporty personality. The driver is welcomed by a new layout and a revolutionary ergonomic interface where the main controls are all clustered on the steering wheel.
With the Ferrari 458 Italia, Maranello has brought a highly distinctive new car to its 8-cylinder range. The company now offers two models that share a common, race-derived DNA, both exceptionally sporty and fun to drive in true Ferrari tradition, but aimed at two very different kinds of client. While the Ferrari California was created for owners requiring a more versatile sports car with a practical edge, the 458 Italia is designed for owners for whom the priority is uncompromising on-road performance with occasional track day capability, but who still demand a car that is useable in day-to-day driving like all Ferrari’s recent models.
