The design philosophy of the suspension layout has not changed and it continues to use pull-rods both front and rear, but it has been refined to the limit, in order to gain as much aerodynamic advantage as possible, especially at the rear. The bodywork elements have been redesigned to allow for changes to the positioning and layout of the exhausts. The dynamic air intake, mounted above the cockpit has been redesigned, as have been the intakes to the side pods, which in turn have also been optimised in aerodynamic terms, while maintaining unchanged the overall cooling system.
The rear of the car is much narrower and more tapered on the lower part. The configuration of the front and rear wings derives directly from the last versions used on the F2012, partly because development of that car ran all the way to the final race of last season. However, the aerodynamic elements shown on the car are only those from the initial phase of development: significant modifications will be introduced in the weeks leading up to the first race and a busy development programme is already planned. The drag reduction system on the rear wing has been revised and optimised to make the most of the modifications to the Sporting Regulations that come into play this year. There are detailed changes to the design of the brake ducts, both front and rear and work has been carried out with Brembo on optimising the braking system overall. During both the design and production stages, great attention has been paid to weight reduction and on increasing rigidity.
