Honda Marks 40 Years of Innovation at Anna Engine Plant in Ohio

Honda commemorates the 40th anniversary of its Anna Engine Plant (AEP) in Ohio, a cornerstone of the company's manufacturing prowess and a pivotal player in the transition towards electrified mobility. Since its inception in 1985, AEP has grown from a modest facility into the largest Honda auto engine plant globally, with a staggering production of over 32.5 million engines. The plant's journey reflects Honda's commitment to innovation, adaptability, and quality, underscored by a $2.9 billion investment that has expanded its operations to over 2.8 million square feet and employed 2,900 associates.

The Anna Engine Plant stands as a testament to Honda's flexible manufacturing approach, capable of producing internal combustion engines (ICE), hybrid powertrains, and all-electric motors on the same production lines. This versatility is crucial as Honda navigates the shift towards electric vehicles (EVs), with AEP already integrating new processes like megacasting, friction stir welding, and Minimum Quantity Lubrication machining to produce aluminum EV battery cases. These components will be essential for the upcoming EV production slated to begin in 2026, marking a significant milestone in Honda's electrification strategy.

Over the years, AEP has manufactured a diverse range of engines, from fuel-efficient hybrids to high-performance models, including the 500 hp 3.5-liter twin-turbo V6 engine for the Acura NSX. The plant's ability to produce such a wide array of powertrains highlights its critical role in Honda's global operations and its contribution to meeting consumer demands across different vehicle segments.

As part of the Honda EV Hub in Ohio, AEP is at the forefront of the company's efforts to embrace the future of mobility. Honda's significant investments in Ohio, including over $1 billion to retool existing facilities for EV production and a $3.5 billion joint venture for an EV battery plant, underscore the state's importance in Honda's long-term strategy. The Anna Engine Plant's 40-year legacy of innovation and quality sets a solid foundation for Honda's next chapter in electrification and sustainable manufacturing.
