What does the number in front of Audi's TFSI mean?

Audi's tail badge number represents the "G-value," which indicates the vehicle's acceleration performance. It refers to the time taken for the vehicle to accelerate from standstill to 100 km/h. The shorter the time, the higher the G-value, and the better the acceleration performance. The specific conversion formula is: G = 100000 / 3600 / seconds for 0-100 km/h acceleration / 9.8 * 100, rounded to the nearest 0 or 5. However, this formula can only serve as a rough reference. Here is additional information: 1. T: T stands for Turbo, indicating that the vehicle is equipped with turbocharging technology, which uses high-pressure exhaust gases to drive the exhaust turbine at high speed, thereby compressing the intake air via the intake turbine, increasing air density, and simultaneously increasing fuel injection to enhance the vehicle's torque and power output. 2. FS: FS stands for Fuel Stratified, representing the use of Volkswagen Audi's unique stratified combustion technology, a type of lean-burn engine technology.
Haha, I've always found Audi's numbering system quite interesting. For example, the '4' in A4 TFSI actually represents the model's class. Audi's sedan series are categorized from small to large numbers: A1 and A3 are compact models, perfect for city commuting—fuel-efficient and agile; A4 and A5 lean towards midsize, offering more spacious interiors comfortable for five passengers; A6 and A7 are larger, ideal for business or family trips, providing excellent stability on highways; while the A8 is the luxurious flagship, with rear seats resembling first-class cabins. Generally, higher numbers indicate more expensive and imposing vehicles—not just in size but also in performance tuning. For instance, smaller-numbered models like the A3 are sportier and more agile, whereas larger-numbered ones like the A6 prioritize comfort and quietness. TFSI itself refers to turbocharged technology that enhances power efficiency. When car shopping, don't just choose based on numbers—test drive to find what suits your daily style best. Audi's overall positioning is quite clear, covering a wide range from entry-level to premium.
