Design Considerations: Aston Martin Valkyrie Rear Diffuser Shape
The rear diffuser is a crucial aerodynamic component of the Aston Martin Valkyrie, playing a pivotal role in enhancing downforce and overall vehicle stability. Its design is meticulously engineered to meet specific functional requirements and adhere to aerodynamic principles.
The Valkyrie’s rear diffuser is tasked with manipulating airflow beneath the vehicle. By channeling air through its intricate shape, the diffuser accelerates airflow, creating a low-pressure zone that effectively “sucks” the car towards the ground, increasing downforce. This downforce counteracts the aerodynamic lift generated by the vehicle’s high speed, ensuring optimal grip and stability.
Aerodynamic Principles
The Valkyrie’s rear diffuser shape is meticulously designed to exploit aerodynamic principles. Its contours and angles are precisely calculated to create a Venturi effect, where air is accelerated through a narrowing channel, resulting in increased velocity and reduced pressure. This pressure differential between the underside of the diffuser and the ambient air above generates the desired downforce.
The diffuser’s shape also incorporates a Gurney flap, a small vertical extension at the trailing edge. This flap creates a vortex that further enhances the Venturi effect, intensifying the low-pressure zone and increasing downforce.

Computational Fluid Dynamics (CFD)
Computational Fluid Dynamics (CFD) is a powerful tool that can be used to analyze the airflow over a vehicle. CFD can be used to design a CFD model of the Valkyrie’s rear diffuser and validate its accuracy. Once the CFD model is validated, it can be used to analyze the airflow over the diffuser at different angles of attack. This information can be used to identify areas of the diffuser where improvements can be made.
The Aston Martin Valkyrie’s rear diffuser shape is designed to maximize downforce, generating a suction effect that literally sucks the car to the ground. This downforce is crucial for maintaining stability and grip at the car’s extreme speeds. However, the Valkyrie’s weight also plays a significant role in its performance.
With a curb weight of just 1,030 kg ( Aston Martin Valkyrie weight ), the Valkyrie is incredibly lightweight, allowing it to accelerate and brake with astonishing efficiency. The combination of the Valkyrie’s rear diffuser shape and its lightweight construction results in a car that is both incredibly fast and incredibly stable.
CFD Model Design and Validation
The first step in using CFD to analyze the airflow over the Valkyrie’s rear diffuser is to design a CFD model of the diffuser. The CFD model should be as accurate as possible, so it is important to use high-quality geometry and mesh. Once the CFD model is designed, it must be validated to ensure that it is accurate.
