Introduction:
Ford is looking to revolutionize vehicle design with the potential patenting of deployable roof rails and roof racks that can stow away when not in use. These innovative features could help reduce aerodynamic drag, potentially improving fuel economy and extending the range of electric vehicles. The United States Patent and Trademark Office (USPTO) published details of these patent applications on July 11, 2024, which were filed by Ford at earlier dates.
1. Deployable Roof Rails Technology:
One of the patents filed by Ford covers deployable roof rails that would pop up out of channels in a vehicle’s roof on hinges. These roof rails would serve as mounting points for cargo carriers and accessories, similar to the fixed roof rails found on many SUVs. This technology could provide a sleek and aerodynamic design while also offering practical functionality for vehicle owners.
2. Deployable Roof Rack for Pickup Trucks:
In another patent application, Ford introduced a deployable roof rack specifically designed for pickup trucks. This roof rack would be stowed behind the back wall of a pickup’s cab, near the front of the cargo bed, and pivot upward onto the roof when needed. This innovative design could offer pickup truck owners a convenient and efficient solution for transporting cargo without compromising aerodynamics.
3. Importance of Aero Efficiency in the Automotive Industry:
While automakers do not always commercialize patented features, Ford’s focus on improving aerodynamic efficiency aligns with industry trends. Hyundai has developed an active air skirt for EVs to reduce drag, while other manufacturers are incorporating aerodynamic enhancements into their vehicle designs. Maximizing aerodynamics has become crucial in enhancing EV range and improving overall efficiency in modern vehicles.
4. Evolution of Aerodynamics in Vehicle Design:
The automotive industry has witnessed a resurgence of interest in aerodynamics, dating back to nearly a century ago. The development of streamlined shapes, like those seen in the Hyundai Ioniq 6 and Volkswagen ID.7, demonstrates a renewed emphasis on aerodynamic performance. Concepts such as the Mercedes-Benz Vision EQXX showcase the potential benefits of prioritizing aero efficiency and reducing weight to boost EV performance.
5. Potential Impact on Fuel Economy and EV Range:
By patenting deployable roof rails and racks, Ford is positioning itself at the forefront of aerodynamic innovation in the automotive industry. These features have the potential to improve fuel economy, increase EV range, and enhance driving efficiency for consumers. As automakers continue to explore ways to optimize aerodynamics, technologies like deployable roof rails and racks could play a significant role in shaping the future of vehicle design and performance.
In conclusion, Ford’s pursuit of patenting deployable roof rails and roof racks highlights the importance of aerodynamic efficiency in modern vehicle design. These innovative features have the potential to optimize fuel economy, extend EV range, and enhance overall driving performance. As the automotive industry continues to prioritize aerodynamics, technologies like deployable roof rails and racks could revolutionize the way we think about vehicle design and functionality.
