Are the 1.4T engines of Volkswagen and Audi the same?
2 Answers
In various models of the two brands, the engines are the same, but the tuning is different. Below are the relevant introductions of the engines for the two models: Volkswagen 1.4T: (1) Model technology: Represented by the Volkswagen Golf, this engine model is EA211, using TSI technology, commonly referred to as a "direct-injection turbocharged engine." (2) Power: Maximum horsepower 150P, maximum power 110KW, maximum torque 250NM. Audi 1.4T: (1) Model technology: Represented by the A3, this engine model is the same as Volkswagen's 1.4T, with Audi's 1.4T using djs and css to distinguish between National V and National VI emissions, adopting TFSI technology, commonly referred to as a "turbo fuel stratified injection engine." (2) Power: Maximum horsepower 150P, maximum power 110KW, maximum torque 250NM.
I've been into car modifications for over a decade, and both these 1.4T engines are essentially based on Volkswagen's EA211 series. The fundamental architecture—core components like pistons, connecting rods, and crankshafts—is largely identical, and they might even share the same production line. However, the Audi version comes with minor upgrades: the turbo tuning is more aggressive, and the ECU programming has been recalibrated, delivering a noticeably quicker acceleration feel. There are also slight differences in fuel economy due to varied materials—Audi incorporates more lightweight components to reduce consumption. While about 90% of parts are interchangeable, always check specific model numbers for brand compatibility when purchasing components. Pay special attention to sensors, as Audi often uses proprietary parts for enhanced performance calibration. This is crucial during modifications to avoid compatibility issues and prevent warning lights from triggering.
