What is the displacement of 40tfsi?
2 Answers
40tfsi has a displacement of 2.0L, which is determined based on the G-force generated during the vehicle's 0-100 km/h acceleration. The G-force can reflect a car's acceleration capability - the stronger the acceleration, the greater the G-force, and consequently the more power required. In tfsi, 't' stands for turbocharged engine, while 'fsi' represents fuel stratified injection technology. The 40tfsi model uses a low-power version of the 2.0-liter turbocharged engine with a maximum power of 190 horsepower and a maximum torque of 320 Nm. This engine is equipped with hybrid injection technology and uses an aluminum cylinder head with an iron cylinder block.
I've been following Audi's models closely, and the number '40TFSI' actually doesn't represent the engine displacement—it's Audi's performance grade designation. TFSI stands for Turbocharged Fuel Stratified Injection technology, with higher numbers indicating more powerful performance. The '40' typically corresponds to around a 2.0-liter displacement, commonly delivering about 190 horsepower. In a similar system, '30TFSI' represents a 1.5-liter engine with roughly 150 horsepower, while '45TFSI' is an upgraded 2.0-liter version reaching up to 250 horsepower. Audi standardized this naming system after 2017 to allow consumers to easily compare model strengths at a glance, not just for gasoline vehicles. I've personally driven an A4 with the 40TFSI engine and found its power response sharp yet fuel-efficient, making city driving very smooth. This design simplifies the car selection process, but it's important to note that the numbers don't directly correlate with actual displacement—it's best to check the specifications table for confirmation.
