Aerodynamic Efficiency

The LaFerrari has an extremely compact frontal section

Aerodynamics play an essential role in the LaFerrari’s exceptional performance and are further example of the uncompromising carry-over of F1 technology to Ferrari’s production models. The engineers’ aim was to deliver the highest degree of aerodynamic efficiency ever achieved with any road car, with a coefficient of nearly 3, thanks to technical solutions honed with CFD analysis and fine-tuned in the F1 Wind Tunnel. Working closely with the aerodynamics department, Ferrari’s Styling Centre incorporated these advanced solutions into the car’s design and the result is the perfect balance of form and function, making the most efficient use of the air flows around and through the car’s body. What makes this design so innovative is its use of active aerodynamics conceived as a seamless integration of the car’s other dynamic control systems to deliver a genuine breakthrough in overall performance. The integration with the car’s controls and dynamic parameters ensures that the active aerodynamics adjust continually to hone both the downforce and its balance via the front and rear devices. In this way the LaFerrari combines the maximum downforce and minimum drag coefficient at every speed and in every driving condition.Thanks to its low height and reduced overall width, the LaFerrari has an extremely compact frontal section for low drag and the tapered, streamlined shape of the greenhouse optimises the air flow towards the rear cooling intakes.

The front wing was designed specifically to increase downforce by eliminating the negative effects of pitch sensitivity caused by the pronounced splitters. A broad central air vent on the front bonnet channels hot air away from the radiator. The front spoiler directs the external flow to the front of the outlet to improve its efficiency, thus creating compression on the front section of the bonnet which generates downforce. A central flap helps keep the airstream from the vent close to the bodywork to reduce the wake, while the rear radius of the vent reduces drag.

Aerodynamics play an essential role for the design

The scallop behind the front wheelarches boosts the extraction of air from around the wheels and improves the efficiency of the front diffuser as well as increasing downforce. The front wheelarches direct the airflow downwards which is then channelled by the flanks along the groove of the doors to the rear radiators. of the rear wheelarches boost dynamic ram effect which increases power output by 5 CV. The shape of the one-piece rear section and spoiler are designed to maximise downforce.At the rear of the car, a pair of engine air intakes on the top of the rear wheelarches boost dynamic ram effect which increases power output by 5 CV.

A central flap helps keep the airstream close to bodywork

The shape of the one-piece rear section and spoiler are designed to maximise downforce. Meticulous development work was dedicated to perfecting airflow under the car with where a number of advanced solutions were adopted directly from F1. These include front vortex generators to boost downforce and efficiency. A central dam at the front of the car improves the efficiency of the spoiler and the forward section of the underbody. This area in front of the wheels incorporates diffusers which feature different expansion characteristics for the front and the outside of the tyre, with vertical fences which maximise the extraction capacity.

Optimize the airflow under the car

The active aerodynamics package on the underbody of the car plays an essential role as it completely changes the configuration below the car as the active rear spoiler is deployed:

• The flaps on the rear diffuser rise to increase air expansion and thus extraction capacity

• The flaps on the front diffuser rise to increase expansion and generate the downforce required to balance that at the rear

• The guide vane on the front underbody, which at high speeds channels excess air away from the front radiator to reduce drag, closes to maximise efficiency.
