So, what is a Subaru BOXER®? It’s a unique design where the engine’s pistons move horizontally, opposite each other, rather than vertically or in a V-shape. This flat layout gives the Subaru engine its signature balance and smooth operation.

The name “boxer” comes from the motion of the pistons—they move back and forth like two boxers throwing punches. When you look at a Subaru BOXER® engine diagram, you’ll see the pistons aligned in a low, wide position. This placement lowers the engine’s center of gravity, which stabilizes the car and enhances cornering precision.

You can feel this balance every time you take a tight curve or merge confidently onto I-95 with your next Subaru.

Subaru builds nearly every model with the Subaru BOXER® engine, and for good reason. This design enhances performance, safety, and reliability while giving Subaru vehicles their distinct driving feel.*

Here’s why Subaru sticks with this proven design:

• Exceptional Balance: The horizontally opposed layout distributes weight evenly, keeping the car stable and agile on every drive.
• Improved Safety: The low engine placement enables it to slide under the cabin in the event of a severe front collision, thereby helping to protect passengers.
• Smooth and Quiet Operation: The opposing pistons cancel out vibrations, providing a refined and quiet ride for you and your passengers.
• Durability: The design minimizes internal stress, helping the Subaru engine last for many years with consistent performance.

If you’re driving a Subaru Outback, Forester, or Crosstrek, you’ll enjoy the exact poised handling and reliable power that the Subaru BOXER® engine delivers.

The Subaru BOXER® engine can suit all your local needs while handling the demands of local roads and weather conditions, offering reliable:

• Fuel Efficiency: The engine’s balanced design helps deliver strong power without wasting energy, resulting in dependable fuel economy.
• Responsive Performance: Its even torque distribution ensures quick acceleration.
• Better Control with AWD: When paired with Subaru’s Symmetrical All-Wheel Drive, the boxer engine provides a smoother, more stable ride on wet or uneven surfaces.

From daily commutes to weekend beach getaways, this engine’s balance and efficiency make it fitting for sunny skies to rainy weather.
