The Design – Pressure Contour on Rear Spoiler McLaren 570S Car | ANSYS Fluent
This simulation is about an Analysis of Pressure Contour on Rear Spoiler McLaren 570S Car using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
The McLaren 570S rear spoiler design ranges from a standard, elegantly integrated unit to more aggressive, high-downforce options like the MSO kit or aftermarket carbon fiber wings. The factory spoiler is designed to complement the car’s organic form, while aftermarket wings often focus on increasing downforce for track performance through materials like carbon fiber, though they are designed to maintain a cohesive aesthetic.

Picture 1. McLaren 570S Car
Factory spoiler
- Design:
The standard rear wing is a subtle, integrated part of the 570S’s flowing body lines. It is designed for aerodynamic efficiency and to maintain the car’s elegant, performance-oriented look. - Features:
It includes a central high-mounted brake light for safety and a seamless aesthetic.
MSO Defined High Downforce Kit
- Design:
This official kit is designed for a more aggressive, race-inspired look, adding significant downforce. - Features:
It is made from carbon fiber for strength and light weight. The wing has contrasting end panels and is supported by dynamic pylons, which are finished in high gloss black with Palladium Grey inserts.
Aftermarket spoilers
- Design:
Many aftermarket options, such as those from NOVITEC, ZACOE, and others, are designed to enhance both the look and performance. They often feature a more aggressive style, sometimes inspired by larger models like the 600LT, while aiming to integrate well with the 570S’s overall design. - Features:
- Material: Typically made from high-quality carbon fiber for strength and weight reduction.
- Performance: Engineered for increased downforce and high-speed stability.
- Aesthetics: Designed to improve the vehicle’s aggressive stance without being a drastic visual departure from the original.
- Examples:
- NOVITEC: A rear spoiler designed to fit precisely with the 570S’s rear end, as shown on the NOVITEC website.
- ZACOE Carbon Fiber Rear Wing: An aerodynamically optimized upgrade designed to integrate seamlessly with the body lines, according to Bulletproof Automotive.
This analysis has tried to simulate and analyze of Pressure Contour on Rear Spoiler McLaren 570S Car using ANSYS Fluent software.
Geometry & Grid
The geometry required for this analysis was generated by Ansys Design Modeler software. The meshing required for this analysis was also generated by Ansys Meshing software. The mesh type used in this analysis is unstructured. The total number of volume properties for geometry is 2,6837e+009 mm³.
Model
In this analysis, the k-epsilon (2 equation) turbulence viscosity model is used to check the fluid flow. The standard wall function is used near the wall.
Boundary Condition
The flow of primary input design modeler geometry for this analysis is considered as velocity magnitude and is 25 (m/s). The flow output range is also considered as a pressure outlet for the flow output region and gauge pressure is equal to 0 (pascal). The wall is also considered a Stationary Wall.
Sizing
According to the type of flow, the Coupled algorithm is used to discretize the Pressure-Velocity Coupling of the solution method. The turbulent kinetic energy and the turbulent dissipation rate has been discretized in the Second Order Upwind.
The results are presented as pressure contours as well as volume rendering.
