Honda Opens New $124 Million World-Class Wind Tunnel in Ohio

Honda has opened its new $124 million state-of-the-art wind tunnel facility, ushering in a new era of development testing capabilities for Honda and Acura products, as well as the company's race vehicles. The new Honda Automotive Laboratories of Ohio (HALO) facility, located at the independent Transportation Research Center Inc. (TRC) in Central Ohio, is the world's most advanced wind tunnel, with three separate state-of-the-art testing functions — aerodynamics, aeroacoustics, and racing — in one location.

Honda created the multifunctional HALO facility to reinforce its commitment to developing fuel-efficient and fun-to-drive vehicles. One of the most advanced of its kind anywhere, the wind tunnel uses a unique interchangeable modular ground plane system capable of aerodynamic vehicle testing of production vehicles and race machines.

With a five-belt rolling road system designed for production vehicle development and a second single wide-belt system for testing both high-performance sports cars and purpose-built race vehicles, the tunnel can generate wind speeds of more than 190 miles per hour.

Even more, the wind tunnel can quickly enable a sophisticated acoustic test system for an aeroacoustic testing mode that utilizes a powerful system of acoustic arrays, made up of microphones and cameras, able to collect real-time data and precision measurement. This becomes even more important as an element of vehicle design as Honda moves toward its electrified future.

As Honda continues to move toward its electrified future, noise reduction becomes an even more important element in vehicle design. Absent engine and exhaust sounds, wind noise will be more noticeable inside the cabin of an electric vehicle. Using the acoustic test system, Honda engineers will be able to identify the precise locations of both interior and exterior noise issues more quickly than ever before.
