What is the difference between 'Inline 6-cylinder' and 'V6'?

[StFinley]

1. Inline 6-cylinder, abbreviated as straight-six, I6, or L6, refers to an engine structure with six cylinders arranged in a straight line. The inline six-cylinder engine has only a single crankshaft, and its design provides relatively balanced power output. However, the engine is longer and has been largely abandoned by most car manufacturers after the widespread adoption of V6 engines. 2. V6 refers to a V-type engine with six cylinders. The six cylinders are divided into two rows, with three cylinders in each row, and a certain angle between the two rows of cylinders. This angle is typically around 60° or 90°, but there are exceptions, such as the Volkswagen VR6 engine with a 15° angle. This engine is the second most common engine structure in modern cars, second only to the inline four-cylinder engine.
