What does 1.4t in a car represent?

[OCameron]

In automobiles, 1.4t indicates that the vehicle is equipped with a turbocharged engine having a displacement of 1.4 liters. The 1.4t nomenclature follows the displacement naming convention, where a larger number before the 't' signifies greater engine displacement. Displacement refers to the volume of fluid intake or exhaust per stroke or cycle - larger displacement engines release more energy per unit time. A turbocharged engine utilizes a turbocharger to increase air intake volume; by raising air pressure and density, it enables combustion of more fuel, thereby enhancing the engine's power output and torque.
