What is the difference between Audi A4 35 and 40?

[DiArianna]

Audi A4 35 and 40 represent differences in gravitational acceleration ratio. Numbers are used to replace displacement, with larger values indicating better acceleration from 0 to 100 km/h. The main difference between A4 30TFSI and 40TFSI models lies in their completely different engines and transmissions. More details are as follows: 1. Increased power: For the current A4 models, the new versions no longer have 35TFSI, starting from 40TFSI as the minimum. Even with the same 2.0 displacement, the new 40TFSI has greater engine power and torque compared to the old 35TFSI, meaning improved overall power. 2. 35TFSI meaning: This indicates the vehicle's acceleration is approximately 0.35 times the free-fall acceleration (gravitational acceleration g). Free-fall acceleration to 100km/h takes about 2.83 seconds, so this vehicle requires roughly 8.1 seconds to reach 100km/h (35TFSI, 40TFSI, 45TFSI, 50TFSI etc. use 5 as quantization unit, with certain quantization errors).
