What is the engine displacement of the Audi Q5 40TFSI?

[VonGabriela]

40TFSI is a model designation used by Audi in the Chinese market, which has undergone adjustments in displacement labeling. Instead of the traditional naming method based on displacement (e.g., 1.8T, 2.0T, 2.4), it now uses a number derived from the G-value calculation of acceleration from 0 to 100 km/h. The number 40 represents the vehicle's acceleration magnitude. TFSI indicates a 2.0-liter displacement. Below are some details about TFSI: 1. TFSI is Audi's patented technology, meaning Turbocharged Fuel Stratified Injection engine. Since stratified combustion technology must rely on direct fuel injection, it can be simply referred to as a 'stratified combustion turbocharged engine.' The 'FSI' stands for Fuel Stratified Injection, which refers to the combination of direct fuel injection and stratified combustion technologies. 2. The TFSI in Audi models adds a 'T' to FSI, representing turbocharging technology. However, due to the quality of fuel in China not meeting the requirements for stratified combustion, the FSI models in China have eliminated the stratified combustion technology, retaining only the direct fuel injection.
