A Ferrari revelou os primeiros detalhes oficiais acerca do 458 Italia, o sucessor do F430.

A designação do novo modelo advém do seu motor: um 4.5 V8, o primeiro bloco central traseiro com injecção directa, da Ferrari. Este debita 570 cv de potência às 9000 rpm e conta com um binário máximo de 540 Nm às 6000 rpm. Associado a uma caixa de dupla embraiagem com sete velocidades, permite acelerar dos 0 aos 100 km/h em menos de 3,4 segundos e atingir uma velocidade máxima de 325 km/h. Apesar do novo bloco ser consideravelmente mais potente do que o anterior V8, o Ferrari 458 Italia emite 320 g/km de CO2 e apresenta um consumo médio de 13,7l/100km.

O 458 será construído na nova fábrica de Maranello, juntamente com o California. A sua apresentação oficial está marcada para o Salão de Frankfurt, em Setembro.

Lá se vai a minha esperança de ter um Ferrari de entrada de gama... :-..

Acho que este se posiciona muito perto do 599 em termos de potência e provavelmente de preço. Não sei se será boa jogada, mas eles devem ter isso bem estudado.

Gosto, mas não me encheu logo olho como o 430, não gosto muito dos faróis e tb preferia 2 escapes duplos atrás em vez do triplo.

Eu acho que o escape duplo, só, chegava e sobrava. Ou então sim, como dizes, 2 escapes duplos, um em cada lado do carro.

The Ferrari 458 Italia draws inspiration from the Enzo and takes a new look influenced by the Mille Chili concept car.

Ferrari has confirmed that the car, codenamed F142 and long rumoured to be named the F450, will be called the 458 Italia. The name derives from the powerplant: a 4.5-litre V8 which Ferrari claims has the highest specific output of any normally aspirated car engine.

It certainly has more in common with superbikes than cars; at 127bhp per litre, the specific output is greater than that of many turbocharged engines.

The high-revving 4498cc V8 has very light internal parts and tiny piston skirts, resulting in low rotation inertia and a 12.5:1 compression ratio. It puts out 562bhp at 9000rpm, 500rpm higher than the 430. That makes it the highest-revving Ferrari road car ever.

It means the 458 Italia will be ferociously fast, and Ferrari claims it will sprint to 62mph in under 3.4sec on its way to a top speed of “over 200mph”.

While advanced engine electronics and lightweight parts underpin the extra performance, this will be the first mid-engined application of Ferrari’s direct injection fuel system, which appeared first on the front-engined California. It also runs Ferrari’s now-traditional flat-plane crankshaft.

The 458’s engine will be one of the most flexible in Ferrari’s history, too, with 398lb ft of torque arriving at 6000rpm. While that sounds peaky, it’s only two-thirds of the way through the 458’s rev range, and over 80 per cent (318lb ft) is available from 3250rpm.

The direct fuel injection has also helped cut CO2 emissions, producing a claimed 320g/km of CO2, even though it is faster and produces significantly more power than the 483bhp F430 and the 508bhp 430 Scuderia.

Dual-clutch ’box

Ferrari learned a lot developing the seven-speed dual-clutch gearbox for the California and it has had to do even more development to fit the unit into the 458 Italia’s engine bay, under the curvaceous glasshouse.

The dual-clutch unit from the California has been modified with different ratios and now shifts even faster than the 430 Scuderia’s 0.06sec. The gearbox’s shift style is likely to be slightly more aggressive than the California’s.

The E-Diff differential and the F1-Trac skid control system have long been the flagship carryover technologies from Formula 1, but the 458 Italia takes them even further and adds another piece of F1-derived technology to the brakes.

Instead of using individual ECUs for the E-Diff and F1-Trac, the 458 Italia has one ECU to control both (as well as the ABS system), resulting in streamlined processing and communication. Ferrari claims a 32 per cent increase in acceleration over the F430 (itself no slouch) out of corners.

The brakes feature a new system called ‘prefill’. When the driver’s foot lifts off the throttle, the pistons in the calipers move the pads towards the discs; that helps to reduce the stopping distance from 62mph to just 32.5 metres.

Aluminium chassis

Ferrari has used its experience from designing the 430 Scuderia’s suspension to create the 458 Italia’s double wishbone front set-up and multi-link rear end, all bolted directly to the aluminium chassis. It’s been developed with the help of Michael Schumacher, who was spotted testing the car.

Ferrari has close ties to aluminium specialist Alcoa, which has built a factory near Modena to produce chassis for the firm. The 458 Italia’s frame uses ideas from both the 430 Scuderia and the Mille Chili concept car.

It uses more advanced bonding techniques than the 430 did, along with manufacturing processes more in line with the aero industry.

F1 wind tunnel

While the 458 was designed by Pininfarina, the shape has been developed using Ferrari’s F1 wind tunnel. The bases of the black intakes in the front bumper deform at speed, closing up the intakes and reducing drag. These intakes also provide downforce and feed air though the radiators ahead of the front wheels.

The car’s shape makes air curve around the cabin and run over the integrated tail spoiler. The flat undertray enhances the effects of the rear diffuser to create 140kg of downforce at 125mph.

Inside, the 458 Italia will take the opportunity created by the more luxurious California to become the sportiest V8 in the family. Ferrari says the steering wheel and dashboard are “new innovations in production cars”; expect a development of the firm’s wheel-mounted manettino switch.

The 458 will be built alongside the California in a new production facility at Maranello.

The car will be launched at the Frankfurt motor show next month and is expected to go on sale in the UK next spring. It will be more expensive than the F430, so expect prices to start at around £150,000.

Mais 80cv que o F430 e mais de 9000rpm ;)

458 Italia -> 0-100kmh em 3.4seg

F430 -> 0-100kmh - 4seg

F430 Scuderia -> 0-100kmh - 3.6seg

Agora vamos la ver se em pista se mantem mais rapido que o F430 Scuderia (este ja é mais rapido que o Enzo) até porque o Scuderia pesa menos 30Kg

Euromilhões... dava mesmo jeito!

Mais imagens, vídeos e até mesmo SONS clap.gif ... em http://www.458spider.com/

Será possível pedir à administração para disponibilizar o bbcode do sapo vídeos, para colocar vídeos aqui no forum, tal como acontece com o youtube?

Agradeço desde já se for possível e até deixo um link para o download do mesmo!
