Anna Engine Plant (AEP) celebrates milestone of 30 million engine production in May 2023


ANNA — In May 2023, the Anna Engine Plant (AEP) celebrated the production of its 30 millionth engine, a remarkable achievement in its history. This impressive milestone 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 38 years, AEP has played a pivotal role in powering Honda and Acura vehicles around the globe, ranging from compact cars to SUVs and hybrid models. It is a symbol of Honda’s unwavering commitment to engineering innovation and quality craftsmanship.

In 2022, Honda’s Anna Engine Plant released a new 2.0-liter Atkinson-cycle engine with additional direct multistage injection for cleaner combustion. It was designed for Honda’s latest hybrid powertrain and made its debut in the 2023 CR-V Hybrid, produced in Canada, Indiana, and Ohio. This engine is part of the process that will allow Honda to reach its goal of 100% electrified sales by 2040.

As Honda continues its journey into the future, AEP has begun manufacturing electrified products to align with Honda’s plan for an expanded hybrid and electric vehicle lineup. While change is inevitable, AEP’s internal combustion engines remain essential to Honda’s current offerings, demonstrating the plant’s adaptability and flexibility.
