Ferrari is planning to launch its first hybrid model "in the near future." It revealed the new composite chassis in Paris, which it says is derived directly from Formula 1 technologies.

The hybrid model which will be produced in a limited-edition, special series. For this model Ferrari chose not to use the industrial carbon fibre composite manufacturing techniques, such as resin transfer moulding (RTM), normally adopted in the automotive sector, as they did not meet the quality and functional standards Ferrari set itself.

The chassis uses four different types of carbon fibre and is hand-laminated then cured in autoclaves.

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 (M46J). In certain critical areas, such as the doors, very tough T1000 was adopted as it is particularly efficient in terms of impact absorption. Carbon fibre is combined with Kevlar® aramid fibre for the undertray to prevent damage from debris thrown up from the road.

The overall chassis is 20% 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% and beam stiffness is up by 22%.

The materials, design methodologies, construction processes, staff and instruments used are all shared with the Scuderia Ferrari.
