Does the 2005 Subaru Legacy have a boxer engine?

Yes, the 2005 Subaru Legacy was equipped with a boxer engine. The Subaru Legacy is known for its distinctive horizontally-opposed or "boxer" engine design, which has been a hallmark of Subaru vehicles for decades.


Boxer Engine in the 2005 Subaru Legacy


The 2005 Subaru Legacy was available with two different boxer engine options. The base model came equipped with a 2.5-liter flat-four boxer engine, which produced 175 horsepower and 169 lb-ft of torque. Higher trim levels of the 2005 Legacy offered an optional 3.0-liter flat-six boxer engine, which generated 245 horsepower and 215 lb-ft of torque.


Subaru's boxer engine design, where the pistons are horizontally opposed rather than in a traditional inline or V configuration, is a key part of the brand's engineering philosophy. This layout provides several benefits, including a lower center of gravity for improved handling, smoother operation, and a more compact overall package.


Advantages of the Boxer Engine



  • Lower center of gravity for better handling and stability

  • Smoother, more balanced operation due to the opposing piston motion

  • Compact engine design that allows for more interior space

  • Inherent resistance to engine vibration


The boxer engine has been a signature feature of Subaru vehicles for decades, and the 2005 Legacy was no exception. This unique engine design has become a key part of Subaru's brand identity and engineering expertise.
