What does 45TFSI mean for the Audi A6L?

TFSI stands for Turbo Fuel Stratified Injection technology. Here is some relevant information: 1. The earliest Audi models would have labels such as 1.8TFSI, 2.0TFSI, or 3.0TFSI on the right side of the trunk to indicate the engine displacement. Later, to differentiate engine power and acceleration, the displacement labels were changed to G-values, such as 30TFSI, 35TFSI, 40TFSI, 45TFSI, and 50TFSI. 2. The G-value is calculated as the average acceleration (a) for achieving 0-100 km/h multiplied by 10. Taking the new Audi 3.0TFSI and 2.0T high-power engines as examples, the 0-100 km/h acceleration time is 6.2 seconds. The average acceleration is calculated as a = v/t = (100,000/3,600)/6.2 = 4.48. Using the formula, the G-value = 4.48 * 10 = 44.8, rounded to the nearest whole number, 45. Therefore, the new tail badge for the Audi 3.0TFSI and 2.0TFSI high-power engines is 45TFSI, no longer using displacement-based labels.
