Audi’s 35, 40, and 45 represent the horsepower of the engine. The larger the number, the greater the horsepower of the engine and the better its performance. 35 generally represents 1.4T, and 40 generally represents 2.0 T low power, 45 generally represents 2.0T high power. Of course, it can also be understood that the larger the number on the tail and the stronger the power, the more expensive the corresponding model will be. For example, the Audi A4L's 45 is more expensive than the A6L's 40.
