Our engineering process.

Advanced 3D Modeling

Advanced 3D Modeling

We transformed complex engineering concepts into precise 3D geometry using advanced surface modeling, lofts, sweeps, and curvature-controlled features.

Parametric Design & Automation

Parametric Design & Automation

Our car was built around a fully parametric design approach, allowing dimensions to be rapidly changed and multiple design iterations to be automatically generated for testing.

Generative Design

Generative Design

Generative design helped us explore optimized structures based on real loads and constraints, reducing unnecessary material while maintaining structural performance.

CFD & Aerodynamic Optimization

CFD & Aerodynamic Optimization

CFD became our virtual wind tunnel, allowing us to visualize pressure, velocity, turbulence, and wake formation while continuously refining the car’s aerodynamics.

Car Body & Airflow Development

Car Body & Airflow Development

Every major body surface was developed to control how air travels around the car, with a focus on maintaining smooth flow and reducing aerodynamic losses.

Underbody & Venturi Development

Underbody & Venturi Development

We explored underbody channels, ducts, and pressure gradients to manage airflow beneath the car while balancing drag, lift, and stability.

Wing & Wake Optimization

Wing & Wake Optimization

Front and rear aerodynamic elements were developed to control airflow separation, reduce wake, and improve the car’s overall aerodynamic behavior.

Wheel Aerodynamics & Magnus Effect

Wheel Aerodynamics & Magnus Effect

We investigated how rotating wheels interact with airflow, including the Magnus effect, wheel wake, pressure changes, and their influence on drag and lift.

FEA & Structural Optimization

FEA & Structural Optimization

Structural simulations allowed us to evaluate loads, stiffness, and potential failure before manufacturing, helping create lighter and stronger components.

Digital Prototyping

Digital Prototyping

Ideas were developed and evaluated virtually before manufacturing, allowing unsuccessful concepts to be identified early and promising designs to be refined faster.

Wind Tunnel Validation

Wind Tunnel Validation

CFD predictions were validated using physical wind-tunnel experiments, including rotating-wheel testing and modular prototypes with interchangeable components.

CNC Manufacturing

CNC Manufacturing

Our designs were developed around real CNC capabilities, considering tool accessibility, minimum radii, machining directions, and manufacturing constraints from the start.

Rapid Prototyping & 3D Printing

Rapid Prototyping & 3D Printing

3D printing allowed us to quickly manufacture experimental components and modular prototypes, turning digital concepts into physical tests.

Performance & Track Testing

Performance & Track Testing

Final designs were validated through physical testing, measuring real-world behavior and using the results to guide further engineering improvements.
