What kind of engine is in a Subaru Outback?

The Subaru Outback, a popular crossover SUV, is known for its capable off-road performance and all-weather versatility. At the heart of this vehicle is a unique engine design that sets it apart from many of its competitors.


Subaru's Signature Boxer Engine


The Subaru Outback is equipped with a boxer engine, also known as a "flat" or "horizontally-opposed" engine. This engine configuration is a hallmark of Subaru's engineering, and it provides several key advantages. In a boxer engine, the cylinders are arranged horizontally, with the pistons moving in opposite directions. This design results in a lower center of gravity, which enhances the vehicle's stability and handling, particularly on winding roads and off-road terrain.


Engine Specifications


The Subaru Outback is available with two different boxer engine options:



  • 2.5-liter naturally-aspirated four-cylinder engine, producing 182 horsepower and 176 lb-ft of torque.

  • 2.4-liter turbocharged four-cylinder engine, generating 260 horsepower and 277 lb-ft of torque.


Both engines are paired with Subaru's Symmetrical All-Wheel Drive system, which provides excellent traction and control in a variety of driving conditions.


Reliability and Durability


Subaru's boxer engines are renowned for their reliability and longevity. The horizontal layout of the engine components and the inherent balance of the boxer design contribute to reduced vibration and stress on the engine, leading to a longer lifespan. Additionally, Subaru's commitment to quality and attention to detail in the manufacturing process helps ensure that their engines can withstand the rigors of daily driving and off-road adventures.


In summary, the Subaru Outback's boxer engine is a key component that sets it apart from many other crossover SUVs. This unique engine design provides a range of benefits, including improved stability, handling, and reliability, making the Outback a versatile and capable choice for those seeking a rugged and dependable vehicle.
