Ferrari 458 Italia: static front-side view.

The 458 Italia is 15mm longer than its predecessor.

30 July 2009 - Italian sports cars maker Ferrari will unveil its latest mid-rear engined berlinetta model, the all-new 458 Italia, at the 2009 IAA Frankfurt Motor Show (17-27 September 2009).

Compared to its predecessor (the Ferrari F430, successor of the F360 from 2004), the 458 Italia is 15mm longer (4527mm vs 4512mm for the F430), 14mm wider (1937mm vs 1923mm), with a 50mm longer wheelbase (2650mm vs 2600mm) and practically the same height (1213mm vs 1214mm).

The new car's name comes as a tribute to the brand's homeland Italy, one for the world's most reputable countries for design, flair and beauty, while the 458 figure adds the traditional indication to the displacement (45 for the 4.5 litres) and number of cylinders (8).

The engine channels its "notes" through three rear tailpipes.

Like all other Ferrari road-going cars, the new two-seater 458 Italia benefits from the company’s Formula 1 experience, especially in the speed and precision with which the car should respond to driver inputs.

 Engine

Ferrari says that special attention was given to reduce internal friction in the engine and get lower fuel consumption than the F430, although both overall displacement and power have increased.

Like typical racing engines, the new 4499cc V8 - the first Ferrari direct injection engine to be mid-rear mounted, while the Ferrari California direct injection V8 engine is mounted in the mid-front position - has a very low piston compression height, which helped achieve a compression ratio of 12.5 to 1.

With the traditional flat-plane crankshaft, the 4.5-litre V8 engine delivers 425 kW (570 bhp, 578 hp) at 9000 rpm and, with a specific output of 94.46 kW (127bhp/litre). That compares with the Ferrari F430 maximum output of 360 kW/ 483 bhp from the 4.3-litre V8 (375 kW / 503 bhp in the F430 Scuderia version).

The new engine's maximum torque is 540 Nm at 6000 rpm (specific torque of 120 Nm/litre), over 80 per cent of which is available from 3250 rpm.

The 458 Italia is equipped with Ferrari's seven-speed dual-clutch transmission, with specific, sportier gear ratios to match the power and torque curves of the new V8.

The new berlinetta has a dry weight of 1380 kg (the curb weight of the F430 is 1450 kg) with a power-to-weight ratio of 2.42 kg/bhp, a weight distribution of 42/58 per cent front/rear, an average fuel consumption of 13.7 l/100 km (combined cycle, equivalent to 7.3 km/litre, 17.2 US mpg, 20.6 UK mpg), and CO2 emissions of 320 g/km.

Under 3.4 seconds for the 0-100 km/h acceleration.

All these figures combine to provide Ferrari's official figures of under 3.4 seconds for the 0-100 km/h acceleration, and a maximum speed in excess of 325 km/h (where legal and objective conditions permit).

 Chassis

Ferrari indicates that the new chassis, also in aluminium, incorporates various types of advanced alloys along with aerospace industry-derived manufacturing and bonding techniques.

The suspension features twin wishbones at the front and a multi-link set-up at the rear, along with a more direct steering ratio for rapid turn-in and body control.

 Body

A downforce of 140 kg at 200km/h.

The Pininfarina designed Ferrari 458 Italia comes with a compact, aerodynamic shape for simplicity, efficiency and lightness. Styling has been influenced by the requirements for aerodynamic efficiency, such as providing a downforce of 140 kg at 200km/h.

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 Maranello-based sports cars maker indicates that the greater integration of the E-Diff (an electro-hydraulic controlled differential) and F1-Trac (traction control), both controlled by the same ECU, results in a 32 per cent increase in longitudinal acceleration out of corners compared to previous models, adding that the evolution of the control logic, with faster and more accurate calculation of levels of grip, provides better roadholding, handling and ease of control on the limit.

The same ECU also governs the ABS for more precise control over the logic threshold and greater efficiency.

The brakes also feature a prefill function whereby the pistons in the callipers bring the pads closer to the discs on lift off (when the driver lifts off his / her foot from the accelerator pedal) to accelerate brakes application. This has cut the 100-0 km/h braking distance to 32.5 metres.

The Italian brand adds that the 458 Italia features a new kind of steering wheel and dashboard that are the direct result of racing practice, especially from Michael Schumacher's input, as he was involved from the very start of the 458 Italia project. With the new layout and ergonomic interface, the main controls are all clustered on the steering wheel.

The new 458 Italia joins Maranello's 8-cylinder range, with on-road performance and occasional track day capability, while the Ferrari California comes as a more versatile sports car (more).
