Έκπληξη! H Ferrari μπορεί να μην παρουσιάζει στο Παρίσι κάποιο νέο supercar της, αλλά εντελώς απροσδόκητα, έφερε το carbon monocoque chassis της F70, του hypercar που θα αντικαταστήσει την Enzo. Η τεχνολογία του σασί, προέρχεται απευθείας από τον κόσμο της F1.

Έχοντας ήδη αποκαλύψει στην έκθεση του Πεκίνου την αρχιτεκτονική και τα χαρακτηριστικά του υβριδικού της κινητήρα, η Ferrari επέλεξε την έκθεση του Παρισιού ώστε να μας παρουσιάσει το σασί της F70. Δηλώνει ότι απέρριψε την ιδέα να το κατασκευάσει σύμφωνα με τις εμπορικές τεχνικές κατασκευής, όπως η RTM (Resin Transfer Moulding), αφού καμία δεν πληροί την ποιότητα και τα λειτουργικά πρότυπα που έχει θέσει η Ferrari για την F70.

Επικεφαλής του σασί είναι ο Rory Byrne, πρώην επικεφαλής σχεδίασης της Scuderia Ferrari. Το σασί χρησιμοποιεί τέσσερις διαφορετικούς τύπους ανθρακονήματος με πολλαπλές στρώσεις, όλες στο χέρι, που στη συνέχεια ενώνονται μέσω μιας πολύπλοκης διαδικασίας. Η μπροστά ανάρτηση της F70 θα ενσωματωθεί πάνω στο σασί, όπως επίσης η προστασία του ντεπόζιτου, η τραβέρσα, ο χώρος της μπαταρίας και η δομή των καθισμάτων.

Η κύρια δομή του είναι κατασκευασμένη από carbon T800 ενώ σε σημαντικά σημεία έχει χρησιμοποιηθεί Carbon T800UD. Για να διατηρηθεί το βάρος όσο πιο χαμηλά γίνεται, το κάτω και το εγκάρσιο μέρος είναι κατασκευασμένα από carbon M46J, ένας τύπος carbon με ιδιαίτερα υψηλή αντοχή. Στις κρίσιμες περιοχές όπως οι πόρτες, έχει επιλεχθεί η χρήση του πολύ σκληρού T100 που συν της άλλης, είναι ιδιαίτερα απορροφητικό σε περίπτωση σύγκρουσης. Το ίδιο carbon, χρησιμοποιείται και στη μύτη των μονοθέσιων της F1.

Το σασί ζυγίζει κοντά στα 70 κιλά, 20% λιγότερο από όσο ζυγίζει το σασί της Enzo με την στρεπτική ακαμψία να έχει αυξηθεί κατά 27%, ενώ η συνολική ακαμψία κατά 22%. H F70 δεν θα ξεπερνά συνολικά τα 1.100 κιλά και αναμένεται να παρουσιαστεί στα τέλη του 2012 σε κάποιους πελάτες της Ferrari, ενώ επίσημο ντεμπούτο θα κάνει την άνοιξη του 2013.

Ferrari showcases complete range of new-generation models at Paris

World premiere for new F1 composite chassis for upcoming limited-edition special series

Paris, September 27th – The Ferrari display at the Paris Salon showcases the five cars making up the current range, each of which represents a new generation of the company’s 8- and 12-cylinder models.

The F12berlinetta is the most powerful and high-performance V12 ever built, thanks to its 740 hp power output and light, compact architecture. It is flanked by a model with a complementary mission, the FF, our revolutionary four-seater four-wheel-drive car which now sports a new full-length panoramic roof in a special reflective glass (LowE) that gives occupants a genuine open-air driving feeling, while providing thermal and acoustic insulation.

The coupé and the Spider versions of the 458, powered by the V8 that has won the Best Performance Engine Award for two consecutive years, are designed for owners seeking a sportier driving experience. The California 30 – the ‘30’ in the name referring to the reduction in weight and increase in horsepower introduced on the model earlier this year – is aimed at owners who put more store in greater versatility of use.

In line with its “Different Ferraris for different Ferraristi” philosophy, these cars are designed to fulfil complementary roles without compromising their DNA which remains absolutely unique in terms of performance, driving pleasure and advanced technologies. All offer exclusive design that combines modern styling with traditional cues typical of the marque.

Ferrari continually invests significant sums in its product range and this has led to the creation of 8- and 12-cylinder engines whose specific power outputs, levels of torque and maximum rev limits are unprecedented while, at the same time, offering improved fuel efficiency. Important innovations have led to reductions in the weight of our cars, too. In fact, the Scaglietti facility, which specialises in aluminium fabrication, works with more than 25 different alloys, some of which are being used for the first time in the automotive sector.

While power has been boosted by approximately 100 hp across the model range, fuel consumption and emissions have been reduced by 30 per cent compared to four years ago thanks to work done not only on our engines and structural components, but also on aerodynamics, tyres and vehicle sub-systems.

Ferrari continues to invest heavily in innovation and is planning to launch the first hybrid model in its history in the near future. Having already revealed the power unit’s architecture and components, Ferrari has chosen Paris to debut the new composite chassis derived directly from Formula 1 technologies.

Ferrari drew on its vast experience in working with composites for single-seaters for its new hybrid model which will be produced in a limited-edition, special series. For this model Ferrari chose not to use the industrial carbon-fibre manufacturing techniques, such as RTM (Resin Transfer Moulding), normally adopted in the automotive sector, as they did not meet the quality and functional standards Ferrari set itself.

The materials, design methodologies, construction processes, staff and instruments used are all shared with the Scuderia Ferrari, with the formation of a working group which relied on an important contribution from Rory Byrne, Ferrari’s F1 chief designer who was behind 11 of the team’s Championship titles.

The chassis uses four different types of carbon-fibre and is hand-laminated then cured in autoclaves following engineering processes which optimise the design by integrating the different components.

The main structure is made from T800 carbon with local, strategic applications of T800UD, a unidirectional carbon-fibre tape, for reinforcement. To ensure weight was kept to an absolute minimum, the structural underbody and the cross-member are made from another type of particularly high tensile strength carbon-fibre known as M46J. In certain critical areas, such as the doors, very tough T1000 was adopted as it is particularly efficient in terms of impact absorption which is why it is used in the nose-cone of the single-seaters. Carbon-fibre is combined with Kevlar® for the undertray to prevent damage from debris thrown up from the road.

The overall chassis is 20 per cent lighter than the Enzo Ferrari, despite the extra weight required by housing the hybrid components and to meet regulatory obligations. Torsional rigidity is increased by 27 per cent and beam stiffness is up by 22 per cent.
