The house of the prancing horse has chosen Paris to reveal the chassis for its hybrid powered flagship car. Ferrari has been investing heavily in innovation in preparation for its first-ever hybrid model. Ferrari has already revealed the power unit's architecture and components, the debut of the new composite chassis derived directly from Formula 1 technologies shows that we're getting closer to the real thing.

The upcoming limited-edition model draws on Ferrari's vast experience in working with composites for single-seater. Ferrari chose to skip industrial carbon-fiber manufacturing techniques, such as RTM (Resin Transfer Moulding), normally adopted in the automotive sector, which the carmaker feels does not meet its requirements.   

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-fiber and is hand-laminated then cured in autoclaves following engineering processes which optimize the design by integrating the different components.

The main structure is made from T800 carbon with local, strategic applications of T800UD, a unidirectional carbon-fiber 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-fiber 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. The carbon-fiber undertray is refinforced with Kevlar to prevent damage from debris thrown up from the road.

The F70's chassis will be 20 percent lighter than the Enzo Ferrari, despite the extra weight required by housing the hybrid components and to meet regulatory requirements. Despite the lighter weight, torsional rigidity is increased by 27 percent and beam stiffness is up by 22 percent.
