Ferrari F70 chassis revealed, to be 20 percent lighter [videos]

Could weigh 1100 kg.

Ferrari’s highly anticipated Enzo successor (aka F70) won’t be out until next year but the Italian automaker has decided to reveal some partial information about the company’s upcoming flagship model. At the Paris Motor Show this week they are showcasing the car’s chassis which weighs 20 percent lighter than the Enzo's, which is approximatly 70 kg (154 pounds).

Ex Ferrari F1 technical director Rory Byrne said that the car will utilize the latest carbon fiber technology and will adopt several weight-saving and performance measures. One of the novelties of the new Enzo will be the integration of the front suspension pick up points in the chassis, along with the fuel tank protection, dash crossmember, seat structure and battery compartment. The roof will also be integrated through bonding and bolting to the same lightweight chassis. The final version of the new Ferrari Enzo could weigh only approximately 1100 kg (2425 pounds).

The successor of the Enzo will probably be showcased to customers before the end of the year and it will be officially launched in the spring of 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.

With the rise of computers, CAD, use of proven technology, and even consultants, the use of carbon fiber really is not that special any longer especially in the super car segment. Its expected.
