From the Tamiya America website:
The SF70H, the 63rd single-seater designed and built by Scuderia Ferrari, was born out of major regulation changes, with wider tires and cars, plus larger diffusers, meaning that the cars have more aerodynamic down force and greater mechanical grip. Fittingly for the hybrid machine named to commemorate Scuderia Ferrari's 70 years of racing, the SF70H showcases the team's innovation throughout its design. A lengthened nose and arrow-shaped front wing are a consequence of the regulations, as are the fin on the engine cover, and aero appendages ahead of the air intakes on the side pods.
