What makes the Subaru Boxer Engine Special?

The Subaru Boxer Engine

For more than five decades, Subaru has built the Boxer engine for most of its models. This signature powertrain has numerous advantages that improve mechanical performance, comfort, safety and efficiency. The company's sedans and crossover SUVs are powered by this innovative engine block that clearly stands out from conventional powertrains of other makes and models. Let's take a closer look at the technical details of this patented powertrain that propels all Subaru cars.

Technical Specifications of the Boxer Engine

Instead of being aligned in an inline configuration, the cylinders in the Subaru Boxer engine are set up in horizontally opposed positions. This distinct assembly creates several major advantages for every full cycle of combustion. During each stroke, there is more freedom of movement and less vibrations in the cylinders. Compared to a conventional inline engine, the Boxer engine takes up less space under the hood. Consequently, this patented powertrain dramatically reduces the total weight in the front of the vehicle. Engineers also have plenty of flexibility in manipulating the length and width of a horizontally opposed engine. The center of gravity is another important parameter that's dramatically associated with the Boxer unit. It's possible to install this unique engine at a much lower position compared to a conventional inline engine. Therefore, most Subaru sedans and crossover SUVs have a much lower center of gravity compared to their rivals. There are also some safety advantages of having an engine in a relatively low position. During a front crash, the Boxer block is unlikely to protrude through the top of the hood. The entire powertrain assembly is designed to slide smoothly under the cabin to mitigate damage to the driver and front passenger.

In recent generations, the Boxer engine has been available with four or six cylinders. Natural aspiration is standard in the induction system, but some models are available with turbochargers. Most trims easily achieve more than 200 horsepower with 200 pound-feet of torque. There are several other signature mechanical features that are paired with the Boxer engine. The Symmetrical All-Wheel Drive makes Subaru cars some of the most dynamic models on the road. Instead of rolling on an automatic transmission, most Subaru vehicles use a continuously variable transmission with the Lineartronic technology. Nevertheless, some Subaru trims are available with a manual transmission. The Lineartronic CVT also offers manual modes and other cutting-edge settings that facilitate handling.

In recent years, Subaru has introduced the X-MODE to enhance the performance of the powertrain and drivetrain. This feature precisely adjusts wheel spin, engine speed and other important parameters. Additionally, the Active Torque Vectoring function is engineered to calibrate the torque that's produced by the patented engine. Excessive torque can lead to a loss of control on a slippery surface. On the other hand, insufficient torque will make it difficult to navigate surfaces that are covered in rocks, sand or snow. The brilliant engineers at Subaru understand how to combine the horizontally opposed engine with other dynamic mechanical features.
