How wind can make—or break—your EV’s battery range
On a windy day, a headwind or tailwind can significantly affect how far an electric vehicle (EV) travels on a single charge.
To help EVs use energy more efficiently, researchers at The University of Texas at Arlington are partnering with Hyundai Motor Group to develop advanced routing strategies.
Led by civil engineering Assistant Professor Kate Hyun and in collaboration with Hyundai engineers Junyoung Kim, Gisu Bang and Sanghyun Park, the project explores how real-time data—especially wind conditions—can guide drivers along routes that conserve battery power.
“Traditional navigation systems are designed to get you to your destination as quickly as possible,” Dr. Hyun said. “But for electric vehicles, energy consumption is just as important. We’re looking at how factors like wind, road slope and traffic can work together to create smarter, more efficient routes.”
For EV drivers, range is more than just a performance metric. It is key in shaping the overall experience. External factors such as aerodynamic drag from headwinds can significantly affect energy consumption, and incorporating these metrics into route planning remains a major challenge, the Hyundai researches said.
The study proposes energy-efficient routes by considering various factors such as wind, road gradient and traffic, using real-world vehicle data.

“Through this collaboration, Hyundai Motor Company has confirmed the practical potential of eco-routing technology and expects that its future application in real-world services will improve driving efficiency for customers,” Hyundai researchers said.
Rethinking how navigation works
Most GPS systems prioritize the shortest or fastest route, sometimes offering eco-friendly options that reduce emissions. But Hyun’s team is broadening that concept by focusing specifically on energy use in electric vehicles.
The research incorporates real-time wind speed and direction, road grade and traffic conditions.
By combining these variables, the team developed routing strategies that account for how environmental conditions affect battery consumption—something rarely included in existing navigation systems.
“Wind plays a major role,” Hyun said. “A headwind can significantly increase energy use, while a tailwind can help conserve it. By factoring that into routing decisions, we can improve efficiency in a meaningful way.”
When the project launched seven months ago, researchers used Hyundai vehicle data to model how different conditions influence energy consumption. The system is tailored to specific vehicle characteristics, such as size and aerodynamics, so routing recommendations can vary by car.
That level of customization is key to making the technology practical for real-world use.
“This is one of our first opportunities to work directly with a car manufacturer using their actual data,” Hyun said. “It allows us to take what we’ve developed in simulations and move it closer to real-world application.”
The partnership has also provided insight into the intersection of academic research and industry priorities.
While UTA researchers introduced data-driven modeling approaches, Hyundai engineers emphasized the importance of specific variables—particularly wind—in shaping routing decisions.
“It’s been a very interactive process,” Hyun said. “We bring the academic perspective, and they bring real-world constraints and priorities. That combination creates strong synergy.”
The initial phase of the project was completed in December, and discussions are now underway to expand the collaboration with Hyundai’s U.S. operations.
Hyun said the work builds on her broader research into the environmental and public health impacts of transportation systems, including studies on how increased adoption of electric vehicles could reduce emissions and improve community health.
“This project is about more than routing,” she said. “It’s about understanding how we can use data and technology to make transportation systems more efficient and sustainable.”
