What type of engine is in a Subaru?
Subaru vehicles are known for their distinctive boxer engines, which are a key part of the brand's signature all-wheel-drive system. These unique engines, also called "flat" or "horizontally-opposed" engines, are what set Subaru apart from many other automakers.
What is a Boxer Engine?
A boxer engine, also known as a flat engine, is a type of internal combustion engine in which the pistons move horizontally, opposed to each other. This design is different from the more common V-shaped or inline engine configurations. In a boxer engine, the pistons move back and forth in a horizontal "boxing" motion, rather than up and down like a traditional engine.
The main advantages of a boxer engine include a lower center of gravity, improved balance, and a more compact design compared to other engine types. This makes boxer engines well-suited for Subaru's all-wheel-drive systems, as the low center of gravity enhances handling and stability.
Subaru's Boxer Engine Lineup
Subaru offers a range of boxer engines across its vehicle lineup, with displacements ranging from 2.0 to 2.4 liters. The most common Subaru boxer engines include:
- 2.0-liter Boxer Engine: Found in models like the Impreza and Crosstrek, this engine produces around 152 horsepower.
- 2.4-liter Boxer Engine: Powering larger Subaru models such as the Outback and Ascent, this engine generates up to 260 horsepower.
- 2.4-liter Turbocharged Boxer Engine: Available in performance-oriented models like the WRX and STI, this engine can produce over 300 horsepower.
Regardless of the specific displacement, all Subaru boxer engines share the same fundamental design and benefits, making them a key part of the brand's identity and driving experience.
