Scuderia Ferrari SF70H : Présentation de la monoplace de F1 celebra 70 anni di Ferrari


Via une présentation en ligne depuis Fiorano, la Scuderia Ferrari a choisi de présenter sa nouvelle monoplace répondant au nouveau règlement technique 2017. Dénommée SF70H pour fêter les 70 ans de Ferrari, la monoplace prendra la piste pour ses premiers tours de roue aujourd’hui même sur le circuit italien.

Présentation Scuderia Ferrari SF70H


Dans une mise en scène très simple mais avec brio, la Scuderia a présenté vendredi matin dans un garage de sa piste privée de Fiorano sa SF70-H marquant ses 70 ans d’existence comme constructeur automobile. En compagnie de ses champions du monde, Sebastian Vettel et Kimi Räikkönen, et son espoir italien Antonio Giovinazzi, le directeur d’équipe Maurizio Arrivabene et le directeur technique Mattia Binotto sont venus présenter la SF70H pour la saison 2017 de F1.

La livrée de la dernière-née de Maranello revient à un rouge quasiment intégral, mais une touche de blanc réside le long du nez et garnit également l’aileron de requin.

The 63rd single-seater designed and built by Scuderia Ferrari to take part in the Formula 1 World Championship is born out of a regulation change that is without precedent in this category of motor sport.

Generally, in the past, regulations went in the direction of slowing down the cars. However, this year, the rule changes go in the opposite direction, meaning the cars have more aerodynamic downforce and more mechanical grip.

There are several differences between the 668 project and Ferraris from the recent past: the lengthened nose and the arrow-shaped wing are a consequence of the regulations, as is the obvious fin on the engine cover and the more complex aero appendages ahead of the air intakes on the sidepods, whose unusual shape was designed in harmony with the front crash structure.

Visible at the front is a duct that has an aerodynamic role, while behind the driver, the roll-hoop, which incorporates the engine air intake has been completely redesigned. Also updated is the suspension layout, which still retains a push rod design at the front with pull rods at the rear. The hubs and wheel nuts have been redesigned to facilitate the work of the mechanics when changing wheels during the pit stops. Finally, also as a function of the expected increase in performance this year, the power-steering and braking systems have been upsized.

The Gestione Sportiva group has concentrated its efforts on finding the right compromise between downforce and aerodynamic resistance, or drag. The new Pirelli tyres are much wider than in the past, by 6 centimetres each at the front and 8 at the rear.

This increased frontal area constitutes a “brake” on forward motion as does the increased downforce coming from the 2017 specification front wing, floor and diffuser. Countering this effect, the combination of downforce and the bigger footprint from the tyres translates into increased grip, leading to higher cornering speeds.


Moteur Scuderia Ferrari SF70H

Ferrari a modifié son approche afin d’améliorer son unité de puissance, via la technologie d’impression 3D pour un design de piston novateur.

Ferrari has decided to incorporate additive manufacturing into their engine production in order to completely remodel their ignition chamber. By 3D printing the steel alloy piston heads for the 668, Ferrari reportedly thinks it can achieve perfect combustion, with the 3D printed pieces able to withstand 400 bar of pressure. The design is being carried out by Magneti Marelli, an Italian developer and manufacturer of high-end automotive components.


About the power unit, there have been few changes to the regulations. The main one concerns the amount of fuel that can be used by each car during the race: with the predicted increase in performance, with a bigger percentage of each lap spent at full revs, the permitted amount of fuel has increased from 100 to 105 Kg, although the flow rate is still fixed at 100 kg/hour.

The 062 engine is a definite step forward compared to its predecessor, when it comes to chasing performance. The layout of some of the mechanical components on the hybrid power unit has been revised, while other areas maintain a similar layout to the 2016 car. On the sporting regulation front, the abolition of the “Token” system allows the teams more room for development over the course of the season.
