What do Audi 30, 35, 40, 45, and 55 mean?
2 Answers
Audi's 30, 35, 40, and 45 refer to the G-value. It can be understood as the vehicle's acceleration performance being 30%, 35%, 50% of the gravitational acceleration G, respectively. The higher the number, the better the car's acceleration performance. Additional information is as follows: Acceleration performance: Acceleration performance refers to a car's ability to rapidly increase its speed. It is generally evaluated using the car's acceleration performance from a standstill with continuous gear shifts and the acceleration performance in the highest gear and the second-highest gear. The testing method for starting acceleration performance involves placing the transmission in the starting gear, quickly starting the car with the accelerator fully pressed, and accelerating the car. When the engine reaches the maximum power speed, the gear is quickly shifted up until the highest gear is engaged, and the speed reaches more than 80% of the maximum speed, or over 100 km/h for passenger cars. The shorter the starting acceleration time (in seconds), the better the starting acceleration performance.
I often get asked by friends what these Audi numbers mean. Simply put, numbers like 30, 35, 40, 45, and 55 represent the car's power level—the higher the number, the more powerful the engine output. For example, 30 is usually the entry-level, with around 150 horsepower, ideal for city driving with good fuel economy; 35 and 40 are mid-range, like the A4 40 with about 230 horsepower, offering quick acceleration and noticeable push-back feeling; 45 and 55 are high-performance versions, such as the Q5 55, which can reach over 340 horsepower, making highway driving exhilarating. During test drives, I noticed that higher-numbered models consume more fuel, but if you enjoy sporty driving, the 55 is absolutely worth it. Overall, these numbers make Audi's lineup straightforward and easy to understand, helping buyers quickly identify what they want when choosing a car.
