In everyday driving, the type of transmission is a focal point for many car owners, particularly for the Audi A4.
As of August 2019, the Audi A4 is available in two versions: 1.4 liters and 2.0 liters. The 1.4-liter version is equipped with a dry 7-speed dual-clutch transmission, while the 2.0-liter version features a wet 7-speed dual-clutch transmission.
The key difference between these two types of transmissions lies in the cooling method of the clutch: the dry clutch uses air cooling, whereas the wet clutch employs liquid cooling.
Due to the characteristics of liquid cooling, the wet dual-clutch transmission typically offers better transmission efficiency than the dry version.
Additionally, the transmission used in the Audi A4 is developed by Volkswagen's DQ series, which is the same as that used in the Golf model.
The 1.4-liter Golf is equipped with a dry dual-clutch transmission, while the 2.0-liter GTI version uses a wet dual-clutch transmission.
Regarding the engine, the 1.4-liter Audi A4 is powered by the EA211 engine with a maximum output of 150 horsepower, while the 2.0-liter version is equipped with the EA888 engine, producing up to 190 horsepower, and the all-wheel-drive version can reach 252 horsepower.
Generally, it is recommended to change the transmission fluid after 80,000 kilometers of driving for automatic transmissions, but if the vehicle is not frequently used, changing it at 100,000 kilometers is acceptable.
