What does 35tfsi mean?

35 refers to the G-value of the engine, where a higher G-value indicates faster acceleration. FSI is an acronym for Fuel-Stratified-Injection, meaning fuel stratified injection. TFSI stands for a turbocharged (T) FSI engine, abbreviated as TFSI. The specific details are as follows: 1. G-value: 35 refers to the G-value. It can be understood as the vehicle's acceleration performance being 30%, 35%, or 50% of the gravitational acceleration G, with higher values indicating better acceleration performance. 2. Taking the Audi A6L 2.0TFSI (155kW) as an example: For the 2012 Audi A6L 2.0TFSI (155kW), its 0-100km/h acceleration time is 7.3 seconds. The calculation method is 100,000m/3600s/7.3s, then divided by the gravitational constant 9.8, resulting in a value representing the multiple of the vehicle's acceleration compared to free fall. Therefore, the acceleration of this model is 0.3882 times that of free fall. Multiplying by 100 and rounding off gives the final naming number of 40.
I've always been intrigued by the model suffixes on Audi cars. In my understanding, 35TFSI is a performance indicator. TFSI stands for Audi's Turbocharged Fuel Stratified Injection technology, while the 35 is actually a numerical code representing the power level or acceleration grade, typically used in entry-level models like the A3 or Q2. Having driven a 35TFSI car, it accelerates from 0 to 100 km/h in about 8 to 9 seconds, delivering a moderate and practical performance suitable for daily commuting. Audi designed this system to simplify the car selection process—the higher the number, the better the performance. For example, a 45TFSI offers quicker acceleration and a sportier feel. This is similar to Volkswagen's TSI but positioned more upmarket. When choosing a car, paying attention to these numbers can help avoid misinterpreting them as engine displacement. In the 35 grade, the engine might be a 1.5 or 2.0-liter turbocharged unit. For maintenance, it's important to take care of the fuel system to prevent carbon buildup. Overall, the driving experience is smooth and fuel-efficient.
As a driver who frequently interacts with different cars, I explain that 35 TFSI means the number 35 represents the power level, and TFSI is Audi's proprietary technology, standing for Turbocharged Fuel Stratified Injection. This technology improves fuel efficiency and reduces waste. The 35 level roughly corresponds to around 150 horsepower, which is a moderate output. Having driven many Audi cars, the 35 TFSI versions are fuel-efficient and reliable, more than sufficient for city driving. However, higher numbers like 45 TFSI are more powerful but also consume more fuel. This naming convention is not about displacement but rather an acceleration indicator, somewhat similar to Mercedes' numerical system. When buying a used car, checking this can help determine the performance range. Additionally, the engines are often 1.5T or 2.0T, and maintaining clean oil is key to prolonging their lifespan. Overall, this labeling system is quite user-friendly.
