The Subaru Boxer Engine is a type of internal combustion engine characterized by its horizontally opposed cylinder layout. This design allows the engine's pistons to move in opposite directions, which helps to lower the center of gravity and improve vehicle stability. The engine is known for its smooth operation and unique sound, making it a distinctive feature of many Subaru vehicles. One of the key advantages of the Boxer Engine is its compact size, which allows for more efficient use of space in the vehicle. Additionally, the engine's design reduces vibrations, contributing to a more comfortable driving experience. This engine type is commonly found in Subaru models, including the Subaru Outback and Subaru WRX.
