Description
The Verus Engineering Carbon Flat Underbody Panel for the R35 Nissan GT-R is designed to improve underbody aerodynamics by covering the large open tunnel area left exposed by the factory underbody. While the R35 GT-R already achieves an impressive coefficient of drag from the factory, this open tunnel area creates unnecessary aerodynamic drag. By covering and properly shaping this section of the underbody, Verus Engineering was able to further reduce drag and, in certain applications where the vehicle is raked, achieve an increase in downforce.
Using advanced ANSYS Adjoint solver analysis and CFD development, Verus Engineering optimized the panel to reduce the vehicle's coefficient of drag by 0.010 Cd, or 10 points. The purposefully sculpted carbon fiber panel helps smooth airflow through the tunnel area and reduce drag generated underneath the vehicle.
The Verus Engineering Carbon Flat Underbody Panel is manufactured from pre-preg carbon fiber using a machined billet mold, providing a precise and high-quality construction. The panel incorporates a low-drag evacuation duct for heat extraction along with two low-drag NACA ducts designed to assist with transmission cooling.
Every Verus Engineering underbody panel begins with CFD analysis before production. The R35 GT-R's factory tunnel area was modeled using an ANSYS Adjoint solver to identify areas where aerodynamic drag was generated and determine where airflow could be recovered. The resulting panel seals and smooths the underbody transition while incorporating strategically positioned cooling ducts.
The finished panel uses 1.6mm pre-preg 2x2 twill carbon fiber with a matte clear finish and stainless steel hardware throughout. The result is a lightweight, aerodynamic underbody upgrade designed to reduce drag while providing additional cooling functionality.

Science
The Verus Engineering Carbon Flat Underbody Panel was developed specifically to address the aerodynamic drag generated by the open tunnel area underneath the R35 Nissan GT-R. CFD analysis using the ANSYS Adjoint solver identified areas where airflow was producing unnecessary drag and allowed Verus Engineering to optimize the panel's shape for improved airflow recovery.
The finished panel creates a smoother and more controlled underbody airflow path while reducing the drag generated by the open tunnel. The integrated NACA ducts direct cooling air toward the transmission, while the evacuation duct assists with heat extraction without unnecessarily increasing aerodynamic drag.
Testing and CFD development resulted in a documented 0.010 Cd reduction, equivalent to 10 coefficient-of-drag points. On vehicles with an appropriate rake setup, the improved underbody airflow can also contribute to increased downforce.
