Ferrari F138 versus F14 T - side view analysis 29 January 2014
This drawing compares the side profiles of Ferrari's new 2014 car, the F14 T (top) with their 2013 car, the F138 (bottom). Like Force India and Sauber, Ferrari have adopted a 'double step' in the chassis in order to allow a large amount of air to flow under the car, whilst respecting the reduction in chassis height by 100mm to 525mm. As a result of this, there is a steep slope from the low flat nose (1) up to the top of the chassis (2). As the yellow line (3) highlights, the underside of the chassis follows the same shape as the top surface, enabling Ferrari to get plenty of air flowing under the chassis and towards the diffuser, despite the reduction in nose/chassis height. One surprising design aspect of the 2014 car is that the sidepods (4) are very similar in size to last year's - an impressive achievement given the extra cooling requirements of the new power units. The turbo intercooler and various other radiators and cooling systems are housed within the sidepods, so it's advantageous aerodynamically to have kept those small. Another change from last year is that the airbox intake (5) has a more triangular shape, whilst the engine cover (6) has a large fin section which features a small hot air exit for the clutch. Further back down the car, the rear wing is supported by two boomerang-shaped pillars (7), whilst the rear wing endplates (8) are a similar shape to those on last year's McLaren and feature several gills in the lower section. Finally, all the hot air from the sidepods exits through two big oval openings at the rear of the sidepods. These openings are placed very low down - lower even than on the new Red Bull RB10 - and will allow hot air to exit towards the diffuser.
