What does the Audi rear badge 40 or 35 mean?
1 Answers
Audi's rear badge 35/40 indicates the horsepower of the engine. The larger the number, the greater the horsepower of the engine, and the better the performance. The numbers on the rear of an Audi do not represent the engine displacement but rather the vehicle's acceleration value. This 35/40 refers to the acceleration value. Extended relevant information is as follows: 1. Acceleration value: Since 2012, Audi has started using acceleration values instead of displacement on the rear badge. This is because, with the increasing prevalence of new energy vehicles (such as hybrid and pure electric vehicles), a single displacement model can now be tuned to produce different power outputs. 2. Stratified combustion method: Audi divides the acceleration by G (i.e., multiples of G), multiplies it by 100, rounds it to the nearest whole number, and uses a base of 5 to ultimately obtain the number in front of TFSI. The formula is 100000/3600/0-100 km/h acceleration time (seconds)/9.8x100 (rounded). Variable vortices are already generated in the intake tract, causing the intake flow to form the optimal vortex shape as it enters the combustion chamber, pushing in a stratified filling manner so that the mixed gas is concentrated around the spark plug located in the center of the combustion chamber. This allows the lean-burn technology to achieve a mixture ratio of more than 25:1, which cannot be ignited under normal circumstances, thus requiring a stratified combustion method from rich to lean.
