Is the BMW 5 Series equipped with a 4-cylinder or 6-cylinder engine?

[Guzman]

Domestic BMW 5 Series models are all equipped with 4-cylinder engines. For imported BMW 5 Series, there are both 4-cylinder and 6-cylinder engine options. Definition of cylinder count: Cylinder count refers to the number of cylinders in an engine. Common cylinder counts for automotive engines include 3, 4, 6, 8, 10, and 12 cylinders. Engines with displacement below 1 liter typically use 3 cylinders, those between 1-2.5 liters generally use 4 cylinders, around 3 liters usually employ 6 cylinders, approximately 4 liters use 8 cylinders, and above 5.5 liters utilize 12-cylinder engines. Relationship between cylinder count and displacement: Generally speaking, with the same cylinder bore diameter, more cylinders mean greater displacement and higher power output. With the same displacement, more cylinders allow for smaller bore diameters, enabling higher engine speeds and consequently greater power enhancement.
