The SF21 is the 67th to be built in Maranello to compete in the Formula 1 World Championship and is an evolution of last year’s SF1000, as dictated by the regulations, which require the use of the same chassis as in 2020, thus limiting the opportunities for change in many areas. Therefore, the SF21 was developed in all the permitted areas, from the engine, which is completely new, to the aerodynamics and, at the rear end, which is where the two development tokens allowed in the regulations have been used.
The SF21 makes its track debut tomorrow in Bahrain for a Filming Day, during which it can complete up to 100 kilometres for the purpose of acquiring film footage for team partners and media use. The Scuderia’s youngest driver line-up since 1968, Charles Leclerc and Carlos Sainz, will both drive. When the first race of the season takes place on 28 March, the pairing’s average age will be 25 years and 3 days. Before that, they will tackle the only 2021 pre-season test, getting to grips with the new car over three days at the Sakhir circuit.
