What does the T procedure mean?

[KinsleyAnn]

Automobiles with a T at the back indicate the use of a turbocharged engine, while those without a T indicate a naturally aspirated engine. The difference lies in the type of engine the vehicle is equipped with. Compared to a naturally aspirated engine of the same displacement, a "T" engine is more powerful. Turbocharged engines increase air intake: A turbocharged engine essentially uses a turbocharger when necessary, which increases air intake by utilizing the exhaust gases from the engine to drive the turbocharger. Turbocharged engines deliver stronger power: By increasing the air intake, more fuel is injected to match, burning more fuel to achieve stronger power.
