What does 15T mean for a car?

[DelHarper]

15T represents a 1.0T turbocharged engine. This displacement designation is used by Buick vehicles, where 15T, 18T, 20T, and 28T indicate different engine displacements. 15N stands for a 1.5 multi-point fuel injection naturally aspirated engine, 15S represents a 1.5 direct injection naturally aspirated engine, and 15T denotes a 1.0T turbocharged engine. Engine Displacement: Engine displacement refers to the total volume of all cylinders in an engine. It is the working volume swept by the piston moving from the top dead center to the bottom dead center. If an engine has multiple cylinders, the car's displacement is the sum of the working volumes of all cylinders. Engine Overview: An engine is a mechanical device that converts other forms of energy into mechanical energy. The engines used in cars are internal combustion engines, which are heat engines where fuel burns inside the engine. There is a certain relationship between displacement and fuel consumption, but a car with high fuel consumption does not necessarily have a large displacement. To some extent, the size of a car's displacement does not always correlate directly with its fuel consumption.
