What does the number on the rear of an Audi A6 mean?

[DelHayden]

The number on the rear of an Audi A6 represents the ratio between the vehicle's acceleration and gravitational acceleration. Simply put, the larger the number, the stronger the vehicle's power and the better its performance. Here are the relevant details: 1. The number on the rear of an Audi is generally calculated using the following formula: 100 km/h divided by the 0-100 km/h acceleration time, then divided by 9.8 (gravitational acceleration) equals the final number. It's important to note that the last digit is always rounded to end with 0 or 5. 2. Before calculation, unit conversion is required: 100 kilometers = 100,000 meters (m), and 1 hour = 3,600 seconds (s). 3. For example: For an engine with an 8.2-second 0-100 km/h acceleration time, the calculation would be 100,000/3,600/8.2/9.8 = 34%, which is approximately 35%. Therefore, this vehicle would be named 35TFSI. 4. All numbers on the rear of Audi models follow this meaning. Common examples include: 30TFSI, 35TFSI, 40TFSI, 45TFSI, 50TFSI, and 55TFSI.
