What does the 't' on a car mean?

Car's 't' stands for Turbo, which is the abbreviation of Turbocharger, referring to an engine equipped with a turbocharging device. Working principle of turbocharging: It uses the exhaust gas from the engine's exhaust outlet as power to drive the turbine wheel in the turbine chamber. The turbine wheel is directly connected to the compressor wheel in the compressor housing. One end of the compressor housing is connected to the air filter, while the other end compresses the air drawn from the air filter into the engine cylinders, achieving the goal of increasing the air intake in the engine. Maintenance methods for turbocharging: After starting the car engine, do not press the accelerator pedal abruptly; do not turn off the engine immediately after prolonged high-speed operation; choose the appropriate engine oil; regularly clean the engine oil and filter; clean the air filter on time.
After driving for so many years, the most common letter 'T' I've seen in the automotive engine field refers to the turbocharging system. Simply put, it's a set of devices that make the car run with more power. It uses the exhaust gases to drive a small fan, forcing more air into the cylinders, allowing the gasoline to burn more completely, thereby doubling the power output. For example, a regular 1.5-liter engine might only have just over 100 horsepower, while a 1.5T can surge to over 150 horsepower. The advantage of this system is that it's fuel-efficient and highly effective, providing more stable acceleration on highways. However, it may also increase maintenance costs, as the turbo requires regular upkeep to prevent overheating or clogging. Overall, in most car models, like the Audi A4 TFSI, a 'T' after the number signifies a higher-end configuration. Of course, don't confuse it with the reverse gear—that's 'R,' not 'T'.
