Ferrari has unveiled the new SF15-T Formula 1 car that will be driven by
Sebastian Vettel and Kimi Raikkonen this season.
After a disappointing 2014 season that has prompted the resignation of long-time president Luca di Montezemolo, the Italian squad aims to turn things around in 2015.
Vettel is due to give the car its first official run at Jerez in Spain on Sunday, when F1's first pre-season test starts.
SF15-T Features New Nose Section
The most striking visual difference between the SF15-T and its predecessor is the lowering of the front end of the car in accordance with the change of regulations for the 2015 season. After a few seasons of rather unappealing aesthetics, the 2015 rules permit the SF15-T an attractive nose shape which also brings excellent aerodynamic performance. Aside from the nose area, the regulations for 2015 are largely unchanged.
A casual glance at the back of the car reveals a much more tightly packaged rear end which allows more downforce to be extracted from the critical surfaces around the rear of the car. The rear wing family has been extensively redesigned to deliver stable performance in corners while producing a larger DRS effect on the straights. The front and rear brake ducts have been remodeled to produce more cooling of caliper and brake disk while generating more downforce than their 2014 counterparts. Both front and rear suspension kinematics have been overhauled to present the tire to the road in a manner that allows better use of the Pirelli rubber.
Improved Brake-by-Wire System
2014 was the first year of the so called Brake-by-Wire (BBW); a system permitted by the rules as a way of allowing the maximum amount of electric power to be harvested under braking while maintaining an optimal brake balance. In practice, it proved much easier to obtain the former than the latter with the first versions of this system. The BBW was improved greatly during the 2014 season and the SF15-T is further optimized to produce a braking response that should allow the driver sensitive control while braking at the limit.
Weight Increased by 23 lb (11 kg)
The regulations allow the weight of the car to increase by 23 lb (11 kg) with respect to the 2014 car. The 2015 Ferrari SF15-T uses this extra allowance in the regulations to gain some additional performance features under the skin of the car while retaining a workable level of ballast to trim the center of gravity of the car.
