Classification of Audi TT

Not all of them are convertible, but most of them are hard tops in Chinese mainland.

3 FSI, "Direct Injection Engine in Cylinder", "Direct Injection Gasoline Engine".

It is Audi's unique leading technology, which optimizes the intake mixing efficiency to the greatest extent, so that high-efficiency fuel saving and high-power output are no longer contradictory. Audi FSI improves the torque and output of spark plug ignition engine, and at the same time improves the economy by 15%, which lays the foundation for reducing emissions. Compared with the traditional ignition engine, FSI can directly inject fuel into the combustion chamber without throttle, which reduces the heat loss of the engine, thus improving the output power and reducing fuel consumption.

Specifically:

FSI is the abbreviation of fuel stratified injection, which means fuel stratified injection technology in Chinese, and represents a development direction of future engines.

4 TFSI is FSI(T) with turbocharging.

Audi's QUATTRO technology is Audi's unique patented technology. Simply put: quattro? It can effectively distribute the power of the engine to the four wheels at all times, and cooperate with the central differential of Torsten machinery to ensure that all four tires have road grip.
