What does Audi 35/40/45/55 mean?
2 Answers
Audi 35/40/45/55 reflects the acceleration capability of different engines. Generally, 35 refers to 1.4T, 40 refers to 2.0T low power, 45 refers to 2.0T high power, and 55 refers to 3.0T. Here is more information: 1. The 'quattro' following the numbers refers to Audi's four-wheel-drive technology, while 'TFSI' refers to Audi's patented technology, which stands for Turbocharged Fuel Stratified Injection engine. The 'T' represents turbocharging technology. 2. Turbocharging not only increases the engine's air intake but also enhances the power and torque of the car engine, providing more dynamic performance. The difference in power between a turbocharged and non-turbocharged engine can be 40% or even higher.
I discovered that the numbers like 35 and 40 on the back of Audi cars actually represent the vehicle's power level, not the engine displacement. It's calculated based on the car's acceleration capability using a formula roughly like 0.03 × maximum power × gravitational acceleration conversion value. For example, the Audi A4 40 TFSI has an actual power output of around 150 kW, capable of achieving a 0-100 km/h acceleration in just over 7 seconds. This naming convention is quite clever, allowing people to instantly recognize which version is more powerful. In the past, displacement numbers were used, but now with manufacturers adopting electric and hybrid systems, displacement labeling has become even more confusing. I think looking at this number when choosing a car is more reliable than looking at the tail badge, as power directly affects handling and high-speed performance. When buying a car, I recommend test-driving different numbered versions—the difference in experience is quite significant, especially in terms of climbing power and overtaking capability.
