Lamborghini Temerario vs Ferrari 296 GTB: Rear Underbody

The underbody is equipped with vortex generators: three pairs of fins arranged like the branches of a tree increase the rear aerodynamic load, assisting the action of the diffuser which, thanks to a 70% greater surface area compared to the Huracán EVO and an angle increased by 4°, maximizes the vertical extraction of the air flow from the bottom.

The rear incorporates a solution already successfully tested on the Revuelto. The ventilation channels of the rear discs are fed via a NACA duct positioned in the front part of the rear wheel housing, which collects the high-energy flow of the underbody and directs it towards the brake cooling duct.

Thanks to the benefits of adopting active aero which creates the downforce necessary to enhance the car’s performance, the development of the 296 GTB’s rear underbody and the diffuser focused on correctly managing aerodynamic balance and reducing drag.

The significant development of the front, which was needed to balance the car when the active spoiler is deployed, also required the effect on the rear to be counterbalanced in LD configuration i.e. when downforce over the rear does not benefit from the extra 100 kg.

In this regard, the designers fully exploited the opportunities opened up by the layout of the exhaust line which clustered the main heat sources in the upper part of the engine compartment. This allowed the ventilation apertures for the components under the cover to be optimized, thereby clawing back large surfaces for downforce generation, particularly in the central area under the engine, which avoided damaging impacts on the efficiency of the underbody flow.
