What Subaru comes with a flat 6?

Subaru is renowned for its unique flat-six engine, also known as a "boxer" engine. This distinctive engine configuration is a key feature of several Subaru models, providing a distinctive driving experience and impressive performance.

A flat-six or boxer engine is a type of internal combustion engine where the cylinders are arranged in a horizontal, flat position, rather than the more common V-shaped or inline configurations.

This design is a hallmark of Subaru's engineering and contributes to the brand's signature driving dynamics.
