Benefits of the Subaru Boxer Engine

Benefits of the Subaru Boxer Engine

Most auto manufacturers that use a four-cylinder engine do so with four vertical cylinders in a line, called an Inline-4 or I4 engine. While this has long been a popular engine design, Subaru started using a flat-four, or H-4 engine. Instead of the cylinders being verticle, an H-4 engine has horizontal cylinders that oppose each other, hence the name Boxer. Since then, Subaru has used the Boxer engine in the entire lineup! Here at Reedman-Toll Subaru, we're committed to keeping our customers well-educated on the brand we sell. That's why we'd like to take the time to answer some of the most common questions regarding the Subaru Boxer engine. Keep reading below to learn more!

What different Boxer engines does Subaru use?

There are four engines that Subaru uses, all of which are Boxer engines. The 2.0-Liter flat-four is standard under the hood of the Crosstrek and Impreza, providing 152 horsepower. The 2.4L flat-four is standard under the hood of the all-new 2022 BRZ and offers 228 horsepower. This same engine comes with a turbocharger for the Ascent, and select Legacy and Outback trims to kick out 260 horsepower. A 2.5L Boxer is standard in the Outback and Forester, while available to select Crosstrek trims. The 2.5L displacement offers 182 horsepower. Exclusive for the WRX lineup is a 2.0L turbocharged Boxer that pumps out 268 horsepower with faster acceleration and better throttle response. Lastly is a 2.5L turbocharged Boxer that rips out 210 horsepower for race-proven power. This is standard under the hood of the STI lineup. Next, we'll give you a look at a few of the Boxer engine's benefits.

Better efficiency

The Boxer engine's flat layout allows output to flow from the engine directly to the transmission. This direct flow reduces inefficiencies that can decrease fuel economy. The latest Boxer engine generation is more eco-friendly in its ability to still produce plenty of power while using a minimal amount of fuel.

Low center of gravity

The most prominent benefit to the Boxer engine is the lower center of gravity that it provides. The flat-laying, horizontal design of the Boxer engine offers better balance and stability while driving due to the low center of gravity it gives. Furthermore, the unique punch and counter punch counteracts the force of the opposing piston. This balances out the engine, keeping it level even while running. The flat layout of the Boxer engine offers more responsive handling as the vehicle is balanced. Conversely, inline or V-cylinder engines don't have the same symmetry as the Boxer engine, creating a higher center of gravity and uneven weight.

Longevity and safety

The Boxer engine's horizontal design and balance cause the engine to produce less vibration as the opposing pistons move. This adds to the engine's durability and allows the Subaru to last longer and emit less noise by running smoother. Engines that have fewer vibrations operate smoother and provide a more comfortable and quiet ride. The Boxer engine's low center of gravity also protects in the event of a frontal collision as it allows the engine to drop below the passenger area instead of into it.
