Is the Subaru Outback a Domestic Car?

[TuckerDella]

Subaru Outback is an imported car model. More relevant information is as follows: 1. Subaru is the only automobile manufacturer besides Porsche that uses a horizontally opposed engine. The pistons on either side of the crankshaft in an opposed engine resemble two fists facing each other. The Outback is equipped with a 6-cylinder 3.0-liter horizontally opposed engine, which has the advantage of a lower center of gravity compared to a V-type engine, less vibration, and the power output shaft aligns with the drive shaft direction, eliminating the need to change the power output direction, thus achieving high transmission efficiency. However, the structure of the horizontally opposed engine is relatively more complex. 2. An opposed engine can be considered as a V-type engine with an angle of 180 degrees. Comparatively, its valve system is distributed at both ends, and the ignition interval is unique, making maintenance somewhat difficult. The lubrication system has relatively higher technical requirements, and the engine occupies more space, making its application more troublesome compared to a V-type engine. Particularly due to the lubrication system and the large space it occupies in the engine compartment, only Porsche and Subaru use horizontally opposed engines.
