Which Cars Are Equipped with Horizontally Opposed Engines?

[AaronFitz]

Cars equipped with horizontally opposed engines include Subaru and Porsche. In a horizontally opposed engine, the pistons are evenly distributed on either side of the crankshaft, moving horizontally left and right during operation. The advantages of horizontally opposed engines are: 1. Fewer moving parts allow for higher engine speed and power; 2. Lowering the vehicle's center of gravity enhances driving stability; 3. The moments generated by the pistons on both sides cancel each other out during operation, reducing noise. Horizontally opposed engines are also known as H-type engines and are a variant of V-type engines, typically featuring 4 or 6 cylinders.
