Ferrari unveiled their new Formula One car, the SF70-H, on Friday with the minimum of fanfare after a disappointing 2016 season but plenty of hope among fans that the Italian team will return to winning ways.
The online presentation for a car that Ferrari needs to propel them back to the top, after failing to win any races last season, was short compared with some other teams’ offerings.
Ferrari finished third overall in the championship, 70 points behind runners-up Red Bull although the 70 in the SF70-H designation alludes to the sportscar company’s 70th anniversary.
Under new regulations Formula One cars are lower and wider this season, and with bigger front and rear tyres, that should allow them to shave several seconds off each lap.
Former world champions Sebastian Vettel of Germany and Finland’s Kimi Raikkonen are due to start pre-season testing for Ferrari in Barcelona on Monday.
Ferrari last won the constructors’ championship in 2008 and the drivers’ title with Raikkonen in 2007. Mercedes, who presented their car both online and on track at Silverstone on Thursday, have won both for the last three seasons.
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.
On this topic, 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.
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.
In contrast to the aerodynamics, when it comes to 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.
