Are all Buick GL6 models equipped with 3-cylinder engines?

[MacKaleb]

Currently, all Buick GL6 models on sale are equipped with 3-cylinder engines. Here is relevant information: 1. The basic principle of a 3-cylinder engine is to convert the chemical energy of gasoline (diesel) into thermal energy. When the mixed gas in the sealed cylinder combusts and expands, it pushes the piston to perform work, thereby transforming thermal energy back into mechanical energy. 2. Main purpose: To provide power for traditional fuel vehicles and new energy hybrid models. An excessively small single-cylinder displacement increases the surface-to-volume ratio of the combustion chamber, leading to greater heat loss and significantly reducing the engine's thermal efficiency; an excessively large single-cylinder displacement lengthens the flame propagation distance, which can easily cause knocking, resulting in no significant improvement or even a decrease in the engine's thermal efficiency.
