flat-four
Subaru's signature engine
A flat-four is an engine configuration with four cylinders arranged horizontally in two opposing pairs, like a boxer's fists.
This layout, also called a boxer engine, sits lower than inline designs, improving a vehicle's center of gravity.
Subaru and older Volkswagen Beetles are known for their flat-four engines: The flat-four gives the car a distinctive rumble.
