The Vandal One aero program has gone through several CFD iterations and surface updates to balance stylistic goals with drag minification. Downforce is relatively easy to make with proper airfoils, but minimizing drag in parallel is what creates for excellent aerodynamic execution.
Maintaining aero balance was absolutely critical to the One, so the consideration of interactions and force vectors on the front wing, front and rear floors, rear diffuser and rear wing was paramount. Through multiple CFD runs, care and precision was placed on how downforce was developed at the expense of drag. Our design team worked with our lead aerodynamicist to preserve Vandal One’s stylistic DNA alongside of surface changes to minimize turbulent airflow and drag.
The front wing on the One is a very important member for air flow management that feeds the side pods and cooling array. Care was placed on analyzing flow streams managed through the front wing and front suspension to feed the PWR radiator and intercooler package needed to keep large power outputs in check.
Much work was focused on generating vortices that would keep airflow close to the bodywork and body assemblies to minimize drag and take full advantage of the aerodynamic devices on the One.
Vandal’s philosophy with the front hood and fenders was to close out the front wing and fender interface as clean as possible to minimize the effect of the front tire. Letting air escape inboard of the fenders without breaking the surface with louvers was especially important to relieve high pressure areas in the upper fender that create lift. This side exit solution can be seen on cars like the Aston Martin Valkyrie, Porsche GT2 RS and Audi eTron R18 LMP.
The rear diffuser has gone through multiple iterations and is responsible for almost 35% of the One’s total downforce.
