Anna Engine Plant preparing to power Honda’s electrified future


ANNA — The Anna Engine Plant (AEP) has long been a vital facility in powering Honda and Acura vehicles, producing more than 30 million engines for automobiles around the world.

Eric Mauk, American Honda Communications, has submitted the following report:

Now Honda’s largest engine plant in the world stands on the precipice of the future, continuing to produce more than a million internal combustion engines, while at the same time, preparing to meet the power needs of the next generation of electrified vehicles.

This vital step in the continued evolution of Honda, and the role that Honda’s AEP 2,900 associates will play in it, is a testament to the plant’s relentless commitment to excellence that began with its inception in 1985.

Originally established as a modest 200,000 square-foot facility with just 94 associates, AEP has evolved into Honda’s largest engine plant in the world, sprawling over 2.9 million square feet, boasting more than 60 production lines covering a wide range of operations, from casting and machining to heat treating and assembly, solidifying its reputation as one of the industry’s most comprehensive and interconnected manufacturing process engine plants.

Over the past 39 years, AEP engines have powered Honda and Acura vehicles around the globe, ranging from compact cars to SUVs and hybrid models, signaling Honda’s unwavering commitment to engineering innovation and quality craftsmanship.

AEP associates are leading Honda’s transition to electrification, which began with hybrid and hybrid-electric models, powered by the Atkinson Cycle 2.0-liter engines produced beginning in 2022. AEP, along with the joint-venture battery plant near Jeffersonville, is part of Honda’s EV Hub in Ohio, where Honda will begin building EVs based on Honda e:Architecture.

As Honda continues its journey into the future of electrification, AEP’s internal combustion engines remain essential to Honda’s current offerings, demonstrating the plant’s adaptability and flexibility.
