What do Audi 35/40/45/55 mean?
2 Answers
Audi 35/40/45/55 reflect the acceleration capabilities of different engines. 35 generally represents 1.4T, 40 usually indicates 2.0T low power, 45 typically stands for 2.0T high power, and 55 commonly denotes 3.0T. These numbers represent G-values, reflecting the car's acceleration. The larger the value, the higher the horsepower and the better the performance. Additional information: 1. The "quattro" after the numbers refers to Audi's four-wheel-drive technology, while "TFSI" represents Audi's patented technology, which stands for Turbo Fuel Stratified Injection engine. The "T" signifies turbocharging technology. 2. Turbocharging can both increase the engine's air intake and enhance the power and torque of the car engine, making the vehicle more powerful. The difference in power between a turbocharged and non-turbocharged engine can be 40% or even higher.
As an Audi owner, I believe these numbers 35, 40, 45, and 55 are Audi's power level indicators, representing the performance level of the engine. The higher the number, the more powerful the car feels and the faster it accelerates. For example, my Audi A4 is the 35 version, which is the entry-level power. It's very fuel-efficient for city driving, but overtaking on the highway can be a bit challenging. My cousin who chose the 40 version says its acceleration is smoother, and it's sufficient for daily commuting. At the 45 or 55 level, like the Q5 Sport version, the acceleration is stronger with noticeable push-back force, though fuel consumption is also higher, so you need to consider your budget before buying. Audi introduced this system to make it easier for us to judge when buying a car, without needing to delve into complex technical parameters. In practice, the numbers are based on the engine's horsepower range—35 corresponds to around 150 horsepower, while 45 can exceed 250 horsepower. This affects not just speed but also insurance premiums and maintenance costs. It's best to spend more time test driving and comparing.
