Who makes Subaru engines in the USA?

Subaru, the Japanese automaker, has been manufacturing engines for its vehicles in the United States for several decades. The company's engine production facilities are located in the state of Indiana, where they produce a range of engines that power Subaru's lineup of cars, SUVs, and crossovers sold in the North American market.


Subaru's Engine Manufacturing Facility in Indiana


Subaru's engine manufacturing facility is located in Lafayette, Indiana, and has been in operation since the early 1990s. The plant, which is part of Subaru of Indiana Automotive (SIA), is responsible for producing the majority of engines used in Subaru vehicles sold in the United States and Canada. The facility employs over 6,000 workers and has the capacity to produce more than 900,000 engines per year.


Engines Produced at the Indiana Facility


The Indiana engine plant produces a variety of Subaru engines, including:



  • Boxer-style flat-four engines, which are a signature feature of Subaru vehicles

  • Turbocharged versions of the flat-four engines, used in high-performance Subaru models

  • Boxer-style flat-six engines, found in the larger Subaru Ascent SUV


These engines are then shipped to Subaru's vehicle assembly plants in the United States and Canada, where they are installed in the company's various models.


Subaru's Commitment to U.S. Manufacturing


Subaru's decision to manufacture engines in the United States is part of the company's broader commitment to U.S. manufacturing. In addition to the engine plant in Indiana, Subaru also operates a vehicle assembly plant in Lafayette, where it produces several of its popular models, including the Outback, Ascent, and Impreza. The company has invested over $4 billion in its U.S. manufacturing operations and employs more than 8,000 people across its facilities in Indiana.


Subaru's focus on U.S. manufacturing has helped the company to better serve its North American customers and respond more quickly to market demands. It has also allowed the company to take advantage of the skilled workforce and favorable business climate in the state of Indiana.
