Introducing the Ferrari SF70H, 2017 Formula 1 Challenger

  Scuderia Ferrari has introduced the SF70H Formula One race car on track at its home-based track in Fiorano. The SF70H designation represents the Prancing Horse’s 70th year in F1, while the letters denote Scuderia Ferrari and the Hybrid poweeplant.

Ferrari sent the SF70H on track right after the unveiling for a proper shakedown and filming purposes. This latest rendition is the 63rd single-seater designed and built by Scuderia to take part in the Formula 1 World Championships. The car is made up of 56 thousand components, produced thanks to the work and collective effort of the Gestione Sportiva team, over twelve months.

The car is visibly different to its recent predecessors, as a result of regulation changes for 2017 aimed above all at increasing performance.

At a glance, the SF70H carries an Italian flag on the “sail” of the engine cover. Another notable feature is  the wider Pirelli tyres (6 cm at the front and 8 cm at the rear). Meantime, the increased frontal area constitutes a “brake” on forward motion as does the increased downforce coming from the 2017 specification front wing, floor and diffuser.

In addition, there are several differences between the SF70H 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.

With regards to the hybrid power unit, Ferrari’s SF70H has managed to address the main concern i.e. the amount of fuel that can be used by each car during the race: with the predicted increase in performance, a bigger percentage of each lap spent at full revs, the permitted amount of fuel has increased from 100 to 105 kg (flow rate remains 100 kg/hour).

The SF70H’s 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.
