Presentation and name
The car was presented in Maranello on January 30, 2015 , and the presentation was broadcast live on the Internet.
The name of the car is made up of the abbreviation of the team name, SF , the year and the abbreviation for turbocharger .
Technology and development
The SF15-T is the successor to the F14 T . Although it is a further development of the previous year's car, due to rule changes for the 2015 Formula 1 season, the vehicle is visually different from the previous model, as the provisions in the area of the vehicle nose have been significantly changed.
The front wing has new end plates with eight individual elements that direct the air flow around the front wheels. After the team had already experimented with a system on last year's car in which air was directed through hollow axle beams on the front axle to the wheel hub in order to improve the airflow around the front wheels, the shape of the front axle suggests that this is the case on the SF15-T System is also present. The lower wishbone is attached very low to the chassis and the two suspension struts that converge there are so close together that they overlap and form a uniform aerodynamic profile. The connection of the upper strut is attached at the highest possible point on the chassis, where there is an internal swivel joint. For the front suspension, Ferrari continues to rely on a system with tension struts. According to Technical Director James Allison , it is more difficult to make a tension strut suspension light and strong, but there are aerodynamic advantages.
Below the airbox, the air inlet above the cockpit, there is now a small, additional air inlet in a triangular shape. The air flowing in here is used to cool the engine electronics. The arrangement of the coolers in the side pods has been changed to achieve a better cooling effect. The resulting optimized aerodynamics alone should make the car several tenths of a second faster per lap compared to the previous year's car.
Large differences can also be seen in the rear area, due to the fundamental revision of the cooling system, the entire rear area is designed much more compact. The rear wing has also been revised, it not only offers more downforce, but also the influence of the activated DRS should now be significantly greater. It is attached to a single strut that extends forward and connects it to the chassis. The revised brake ventilation should also bring more downforce.
After the second week of testing before the start of the season on the Circuit de Barcelona-Catalunya , it became known that the FIA considered the camera mounting on the SF-15T to be illegal and that the team would have to change it before the season opener in Australia .
The SF15-T is powered by the Ferrari type 059/4 , a 1.6-liter V6 engine with a turbocharger.
Painting and sponsorship
The SF15-T is mainly painted in classic red, plus there is a white stripe along the entire length of the car and a wide black stripe underneath. The rear part of the engine cover is completely black. Sponsors visible on the car are Alfa Romeo , Claro, a brand name in several Latin American countries for cellular networks from América Móvil , Hublot , Kaspersky Lab , Santander , UPS and Shell .
Kimi Raikkonen stayed with Ferrari. His new teammate was Sebastian Vettel , who joined the team after six years at Red Bull Racing . Here he replaced Fernando Alonso , who after five years at Ferrari was now driving for McLaren . Esteban Gutiérrez , who was a regular driver at Sauber last year , and Jean-Éric Vergne , who had driven for Toro Rosso , were signed up as test drivers .
