What does Audi Q7 35TFSI mean?
2 Answers
Audi Q7 35TFSI means the acceleration performance is 35% of the gravitational acceleration G; 'T' stands for turbocharging, which includes both turbocharging and supercharging; FSI belongs to direct fuel injection. The advantages of turbocharging include the following 4 points: 1. Increase engine power and torque: It can significantly improve engine power and torque without increasing engine displacement; 2. Good fuel economy: Since the exhaust pressure at low speeds is insufficient to drive the turbine, the fuel consumption level of a turbocharged engine under the same technical conditions is equivalent to that of a naturally aspirated engine of the same displacement; 3. Cost-saving: Turbocharged engines are smaller in size and simpler in structure, reducing R&D and production costs, which are lower than those of large-displacement naturally aspirated engines; 4. Meets the requirements of green travel: Turbocharged engines use turbo and supercharging technology, which reduces carbon monoxide, hydrocarbons, and particulates in emissions, benefiting the environment. Compared to naturally aspirated engines, turbocharged engines also produce less noise.
As someone who frequently studies German cars, I find Audi's naming logic quite interesting. The '35' in 35TFSI doesn't refer to displacement, but rather a power level code – the larger the number, the higher the horsepower. This '35' corresponds to a 2.0T engine with around 230 horsepower. TFSI is Audi's proprietary technology that combines turbocharging and direct fuel injection, reducing fuel consumption by over 10%. Now Audi uses this naming convention across its entire lineup – for example, my neighbor's Q5 45TFSI accelerates 2 seconds faster than the 35 model. This numbering game can be confusing at first, but once you get used to it, you can quickly judge performance levels by the badge. Also note that the new Q7's mild hybrid system affects the badging too, something to watch for when buying used cars.
