Audi's rear numbers represent acceleration values. Below is a detailed introduction to Audi's rear number naming convention: 1. used to differentiate models by displacement, such as 1.8TFSI, 2.0TFSI, 3.0TFSI, etc. After changing the naming convention, displacement was replaced by G-values, such as 30TFSI, 35TFSI, 40TFSI, etc. 2. The G-value is used to represent the overall acceleration feel of the model. The larger the number, the faster the acceleration. The G-value is calculated by multiplying the average acceleration (a) of the vehicle's 0-100 km/h acceleration time by 10. For example, the new Audi A8L 3.0TFSI has a 0-100 km/h acceleration time of 6.2s. Its average acceleration is calculated as a=v/t=(100000/3600)/6.2=4.48m/s², G=4.48*10=44.8, rounded to 45. Therefore, the new rear badge for the Audi A8L 3.0TFSI is 45TFSI, instead of 3.0TFSI. Based on the G-value calculation method above, the G-value on the vehicle's rear badge can be used to roughly estimate the vehicle's 0-100 km/h acceleration time.
