What does 1.5t mean?

[MacAyla]

1.5t refers to a car's displacement being 1.5 liters, indicating that the car's engine is turbocharged. A turbocharged engine is one that relies on a turbocharger to increase the engine's air intake. The turbocharger is essentially an air compressor that uses the exhaust gases from the engine as its power source. A turbocharged engine can significantly increase the engine's power and torque without increasing the engine's displacement. After installing a turbocharger, an engine's maximum output power can increase by approximately 40% or more compared to when it is not equipped with a turbocharger.
