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.

Yesterday someone in the car enthusiast group asked what 1.4t means, and I just repaired a car with this marking. It's actually the engine displacement designation - 1.4 indicates a 1.4-liter displacement, and the t stands for turbocharged. Many compact cars now use this configuration, which essentially packs more power into a smaller engine. For example, a regular 1.4-liter engine might only have 90 horsepower, but with turbocharging it can reach up to 140 horsepower, making highway overtaking much easier. The fuel consumption is actually lower than larger displacement vehicles, which is why popular models like the Golf and Lavida favor the 1.4t configuration.
