SUBARU BOXER Engine Technology Explained
SUBARU BOXER engine design is a unique configuration that takes advantage of horizontally opposed pistons to deliver smooth power across a wide range of vehicle types. A specific type of flat engine layout, the term "boxer" comes from the similarity to a boxer punching their gloves together as the pistons push inward to turn the crankshaft. Unlike inline or V-shaped engines, where pistons generally move up and down, flat-engine pistons move side to side.
Across the entire lineup, Subaru vehicles use a version of this design known as the SUBARU BOXER engine. This arrangement has several inherent advantages that make these engines so integral to the identity of our cars and SUVs, along with the rugged performance drivers expect from them.

SUBARU BOXER Engine Benefits
The SUBARU BOXER engine features a compact layout that synergizes extremely well with key engineering priorities for Subaru, including safety, efficiency, performance, and durability. That's why this type of powertrain has come to be the exclusive engine design you'll see in all new gas-powered Subaru vehicles. Specific benefits of the SUBARU BOXER engine include:
- Low center of gravity: The wide and flat shape of a boxer engine places more weight lower to the ground for improved braking and handling.
- Increased stability: Horizontally opposed engines have less vibration compared to inline engines because the piston movement creates stronger balance.
- Good for all-wheel-drive systems: A flat engine like the SUBARU BOXER can be easily aligned along the drivetrain to deliver power efficiently to all four wheels.
- Enhanced crash safety: Because the engine is mounted on the lower part of the vehicle structure, it can be designed to move away from occupants in the event of a collision.
