Subaru is equipped with a longitudinally-mounted engine. Longitudinally-mounted engine: The Subaru engine is installed at a lower position in the vehicle body, which often results in a lower center of gravity for Subaru cars and a more stable chassis. Additionally, due to its longitudinal mounting, the vibrations generated during engine operation are significantly reduced, enhancing the vehicle's comfort. This is why Subaru has continued to use this engine configuration. Advantages of longitudinally-mounted engines: A longitudinally-mounted engine can lower the vehicle's center of gravity by 15cm. The horizontal movement of the pistons further improves the balance of engine operation, which means that any vehicle equipped with a longitudinally-mounted engine exhibits high stability. This is why top-tier sports cars like Porsche and Ferrari adopt horizontally-mounted longitudinally-oriented engines.

As a long-time Subaru owner, I can confirm its engine layout isn't longitudinal but rather a horizontally opposed transverse design. This means the engine is mounted sideways in the front, not aligned with the vehicle's length. This configuration lowers the center of gravity, providing exceptional stability during cornering, especially on rain or snow-covered roads when combined with the AWD system's superior traction. Subaru has championed this layout for decades - legacy models like the Forester and Impreza all feature it, delivering direct handling feedback and reduced vibration on rough terrain. For those wondering about the design rationale, it primarily optimizes space utilization and weight distribution, unlike BMW's rear-wheel-drive vehicles with longitudinal engines. However, this transverse layout has drawbacks, such as limited tool accessibility during maintenance.

From an automotive technical perspective, Subaru does not employ a longitudinal engine layout; it utilizes a horizontally opposed (boxer) engine mounted transversely at the front of the vehicle, unlike the longitudinally extended configuration found in some luxury performance cars. The transverse setup offers advantages such as a compact structure, suitability for all-wheel-drive systems, balanced weight distribution, and enhanced handling agility. Subaru has built its reputation on this design, with the horizontally opposed engine delivering reduced vibration, lower noise levels, and reliable daily driving performance. Research will reveal that nearly all Subaru models, including the Outback and Legacy, follow this configuration. In contrast, longitudinal engine layouts are typically used in rear-wheel-drive vehicles like the Mercedes-Benz C-Class, where the drive shaft propels from the rear. However, Subaru's transverse layout isn't without drawbacks, as it may exhibit slightly inferior heat dissipation characteristics.

Simply put, most Subaru vehicles don't use longitudinal engines; the engines are mounted horizontally, combined with a boxer design. This results in a lower center of gravity, making the car more stable and safe to drive, especially with its all-wheel-drive performance on slippery roads. Average drivers don't need to understand too much technical jargon—just know that this layout makes the car more balanced and reliable for long-term use. Subaru has adhered to this approach for many years, differing from some high-end sports cars.
