OVERVIEW
The R35 Nissan GT-R has a great cD (Coefficient of Drag) from the factory, but we saw one area we could improve upon. The tunnel area of the R35 is left wide open; and by covering this large area, we are able to further reduce the drag generated by the vehicle's underbody. In some cases where the vehicle is raked, we were able to realize an increase in downforce.
Using ANSYS Adjoint solver and CFD, we were able to reduce the cD by 10 points, or 0.010. The tunnel area of a vehicle is a source of increased drag; by covering this with a purposefully sculpted piece of carbon, we can reduce the drag of the vehicle.
These units are produced from pre-preg carbon fiber off of a machined billet mold. No expense was spared in the production of these tunnel covers. Included in the cover are a low drag evacuation duct for heat evacuation, and two low drag NACA ducts to aid in cooling the transmission.

Science
Every Verus underbody panel starts in CFD before it ever reaches carbon. We modeled the R35 GT-R's factory tunnel area in ANSYS using an Adjoint solver to identify exactly where drag was being generated and where flow could be recovered.
The streamline plot shown here traces airflow across the finished panel: the NACA ducts pull cooling air into the tunnel while the sealed transition sections keep the underbody flat and attached, delivering the 0.010 Cd reduction referenced in the Overview.
