**Revolutionizing Aerodynamics: The Story of Catesby Tunnel**

Innovation in the automotive industry is crucial for progress and efficiency. Autocar’s Innovation Award for 2024 goes to Catesby Tunnel, a former railway tunnel in Northamptonshire that has been transformed into a cutting-edge aerodynamic testing facility. This game-changing project is the brainchild of Rob Lewis, an experienced aerodynamicist who saw the potential in repurposing the tunnel for testing designs.

**The Birth of an Idea**

Lewis, with a background in Formula 1 teams like BAR and Honda, recognized the limitations of existing wind tunnels in the UK. His search for a solution led him to Catesby Tunnel, conveniently located near his office in Brackley. The tunnel’s length, width, and gradient made it an ideal choice for aerodynamic testing, offering advantages over traditional wind tunnels.

**Overcoming Challenges**

Turning Catesby Tunnel into a state-of-the-art facility was no easy task. Securing funding and convincing investors of the project’s viability proved to be a significant challenge. However, with support from Semlep and Subaru, the project came to fruition. Despite facing obstacles like bat conservation and fire regulations, Catesby Tunnel is now operational and proving its worth.

**The Future of Aerodynamics**

Aerodynamics play a crucial role in improving vehicle efficiency and performance. While aerodynamic advancements are often overlooked in favor of other technologies, their impact on fuel consumption and range cannot be understated. With Catesby Tunnel leading the way in aerodynamic testing, the automotive industry is poised for significant advancements in this crucial area.

**Conclusion**

Catesby Tunnel’s transformation from a disused railway tunnel to a cutting-edge aerodynamic testing facility exemplifies innovation in the automotive industry. As the winner of Autocar’s Innovation Award for 2024, Catesby Tunnel stands as a testament to vision, ingenuity, and perseverance in revolutionizing aerodynamics.
