What do Audi 35, 40, and 45 represent?
2 Answers
Audi 35, 40, and 45 represent the horsepower of the engine. The larger the number, the greater the horsepower of the engine, and the better the performance. 35 generally represents 1.4T; 40 generally represents 2.0T low power; 45 generally represents 2.0T high power. Of course, it can also be understood that the larger the number on the tail badge, the stronger the power. Audi is a luxury car brand under Audi AG, a subsidiary of the German Volkswagen Group. Its logo consists of four interlocking rings. Currently, it is a subsidiary of Volkswagen AG, headquartered in Ingolstadt, Germany, and has branches in many countries, including China.
I previously learned about Audi's 35, 40, and 45 tail badge numbers, which represent the car's power output levels rather than direct horsepower figures. They are codes calculated based on engine power (kW). For example, 35 generally indicates 110-130kW, approximately 150 horsepower, suitable for city commuting and fuel efficiency; 40 is medium power, around 140-170kW equivalent to 190 horsepower, offering good acceleration and balance; 45 is the high-end model, such as 185kW or above, around 245 horsepower, delivering strong acceleration and a noticeable push-back feeling. Audi's system replaces the old displacement labels, making it easier for consumers to quickly assess performance levels. Higher power means more enjoyable handling and overtaking, though daily fuel consumption is slightly higher, so buyers should choose based on their driving habits. For instance, I drove the A4 40 version for two years, and it was smooth and sufficient on highways; after switching to the 45, mountain road handling improved significantly, though costs increased by about 15%. Now, electric vehicles like the e-tron also follow this logic, with the 45 number representing stronger range in the electric era.
