The 8C is going to be powered by the F430 engine with added bhp(>500)... Its going to have an all carbon fibre chassi... Dude even if I werent an Alfista I would choose the 8C over any other supercar without second, third, etc thoughts... Its a car that entered the hall of fame from the moment it was first shown... Its more than a car... Its the revival of the genuine Alfa spirit.

I didn't know the 8C was going to be fitted with the F430 engine. That changes everything.

Last i heard it was the 4.3l Maser V8 tuned further to push out 500 bhp, not the F430 motor. There was talk of the ferrari motor a while back, but no mention of it for ages. Where did you get your info?

The new responsible for engineering & design of Fiat Auto is Wester who was for years responsible for Ferrari engineering.....

The famous fibre-carbon splitframe developed for 8c Competizione

Tim145 the F430 V8 is essentially the same that is being used by Maserati.

8c competizione into production in 2007-it's official despite what the German mags report...With 8c alfa romeo will return to Gt races(le mans or fia gt)The chassis is alouminium monocoque strengthen with carbon fibers(like 360 Challenge Stradale or the upcoming F430 Challenge Stradale).Autobody from carbonfiber like enzo,engine V8 4,2 with dry sump and with compressor it will exceed 450hp.Weight 1400-1500kg.Power ratio 3kg/hp...more expensive than F430.

It's official..? Sakiss you have never let us down in the past, but please tell me you have something to back up this very bold claim? And it's going to race in GT races, despite alfa withdrawing from WTCC for financial reasons? Or is it going to replace the Masser MC12 on the track?

And this latest development on the V8, now a 4.2l compressor, what happened to the 500bhp 5.0l V8? There are so many rumoured V8's coming out of alfa at the moment, it is very hard to know what to believe.

Are the 159 and Brera GTA still due to get a 440bhp 4.3l V8?

I R confused.

It will be more extreme than F430 and faster in track cause the use of compressor gives 60nm of torque and an output of 450-500hp....the weight will be around 1400kg.Gta is a different story cause with the use of multiair you have less consumption(-15%) and +10% of torque but only a max of 440hp compared to 450-500 hp of ''lightweight'' 8c.....In my opinion the proper choice was the new 4,7 v8-450hp which it will be fitted to Quattroporte facelift(2007) and to the upcoming Maserati Spyder(2006) but with 500hp.....but i am not the one who decides...the new F430 in 2009 will have a V10 engine....The best Ferrari of this decade will be the upcoming 575 successor with the codename 600 imola(V12 with about 600hp....It will be faster than Carrera Gt,Slr despite cost a lot less...this is the car that will haunt our dreams)

This year they wont join WTCC cause 159 will be ready in the midle of the season and Alfa Romeo competes only to win....Also they haven't yet decided if they will enter WTCC or DTM in 2007.....they said that they examine the possibility for entering FIA GT with 8c(Mc12 will continue participating) and in the future their dream is to return to Le mans sth that every alfista pray for....but it will take more years of development.

SPORTIVA EVOLUTA

The lightening of an automotive vehicle structure, whether it is an engine support, or a complete car body, demands a specific planning so that the mechanical characteristics of the material being used can be exploited to the maximum.

It is therefore necessary in the first place to ask oneself what the structural mission is of the member in question, so that the general proportions can be determined. As such, the first large task is to ensure that the rigidity requirements are satisfied. For example, if a car body is being developed, one of the most important tasks is to ensure that the windscreen mounts are strong enough. Structural members also have to take full advantage of resistance, in the same way as crumple zones do.

A simple geometrical shape (e.g slab, solid beam) has to be derived, which can be used to assimilate the member under study, with the aim being to partially determine by means of analytical processes the state of stress or rigidity. At this point simple functions can be derived for different load situations, that depend on the mechanical characteristics of the material (modulus of elasticity, density, yield value, breaking resistance).

Moreover, the same method can be applied not only in terms of investigating the weight, where the prevailing parameter can be the rigidity or the specific strength, but also towards minimal cost (employing parameters like “density per Euro”).

A comparison between the various materials for each case of basic geometrical shape can then be drawn up (e.g. a slab stressed by bending). As a material of reference, TRIP 800 is chosen, which is a high performance Steel.

For collisions members, such as cross sections, Titanium alloy represents a 60% weight advantage over Steel, and a 30% weight advantage over Aluminium. Sportiva Evoluta makes use of this benefit. For high volume car production the use of Titanium is not feasible however, due to the requirement of sustainable costs.

After detailed structural analyses were conducted for vehicle rigidity, it was decided to use a composite carbon fibre material for the main member.To obtain suitable deformation in impacts, the front and rear crumple zones have been made out of aluminium and titanium. The main module of the so called “Split Frame” chassis design is fixed with a set of elastic mounts, ensuring a desirable compromise between comfort and handling.

Two processes have been used in the manufacturing of the prototype chassis, which ensure a strong design capable of resisting the high forces imposed during high speed handling and crashes; “hand lay-up” manual lamination, and “RTM” resin transfer moulding.The main chassis is split into two parts, the bulkhead and backbone, which are connected by two rows of bolts.

Manual lamination was used for the backbone member,using a sandwich type structure to increase the strength whilst remaining light in weight. This solution consists of two carbon-fibre sheets, between which an ultra low-density honeycomb panel is inserted to improve rigidity characteristics.

The carbon-fibre sheets themselves consist of many layers of overlapping pre-impregnated woven carbon fibres. To optimize torsional rigidity, and to absorb forces transferred from the suspension, the main backbone tunnel has closed sections.

There are two disadvantages of the manual lamination process, the main one being the fact that it would only be possible to produce one to two cars a day. Although the initial investment for the process is very low, the high labour hours, and more specifically the need for skilled labour elevate the variable costs.

The complex shape of the bulkhead section triggered the engineers at the CRF to explore the potentials of the RTM process. The RTM process uses a stamp, into which a glass-fibre mould is initially inserted.A resin matrix containing carbon fibres is subsequently pumped in under a controlled pressure and temperature. To increase the structural characteristics of the member, a reinforcing material called Nomex was also used.

An economic analysis of the RTM process was also carried out during the project, and demonstrated that the high convenience of the technology would allow for a production figure of between 5 to 10 cars a day.

Advantages and possibilities:

-Weight control: The complete chassis (excluding the suspension) weighs less than 100 Kg.

-Chassis performace adapted for super-sports car: The torsional and flexible rigidity assures compliance with the Euro-NCAP standard (offset collision at 64 km/h with deformable barrier).

-Technologies adapted for production volumes of upto 5 cars a day: The labour intensive process of manual carbon fibre lamination has been eliminated by a new process called VRTM (Vacuum Resin Moulding Transfers).

-This concept represents the first application of VRTM where woven carbonfibre is used for certain high strengh chassis members."

The chassis makes use of split frame architecture technology, allowing for different 'upper bodies' to be mounted on the basic 'lower chassis', by means of elastic mounts which provide the necessary comfort by filtering road and engine noise.

Extensive testing revealed a substantial reduction in noise, vibration and harshness, with audible road and engine noise decreasing by 4-6 dBA (over a regular chassis). Not only can different body styles be used on the same chassis,but the chassis itself can also be easily adapted for different wheelbases, engines, and traction schemes (2WD, 4WD).

They should just rebadge the 8C as a Maserati and sell it as the next generation Maserati Spider.
