Audi A6 30FSI has a displacement of 2.5 liters. Extended content: 1. It is equipped with a 2.5-liter V6 naturally aspirated engine, and the vehicle displacement is usually indicated on the body or rear of the car. 2. Displacement is a specialized term in hydraulic transmission, referring to the volume of fluid intake or exhaust per stroke or cycle. The displacement of a car is an important parameter for evaluating a vehicle. 3. The Audi A6 30FSI is a mid-to-large luxury sedan under the Audi brand, with body dimensions of 5015mm in length, 1874mm in width, 1455mm in height, and a wheelbase of 3012mm. It comes with safety features such as driver airbag, passenger airbag, front side airbags, rear side airbags, front head airbags, etc.

From an engine technology perspective, I particularly enjoy studying automotive powertrains. The Audi A6 30FSI is equipped with a 2.5-liter naturally aspirated V6 engine, with a specific displacement of 2498cc. FSI stands for Fuel Stratified Injection technology, which optimizes combustion efficiency, reduces emissions, and improves throttle response. This engine delivers approximately 190 horsepower, with smooth torque distribution and a notably linear driving experience, making it well-suited for urban roads. In terms of fuel consumption, it averages around 10-11L/100km in city driving, while highway cruising can drop to 7-8L/100km. Although modern turbocharged engines offer more power, this naturally aspirated unit boasts higher reliability and simpler maintenance. For modification enthusiasts, the original displacement information is crucial—referencing it when selecting aftermarket parts helps avoid compatibility issues.

As an ordinary person who drives frequently, I've driven the Audi A6 30FSI for several years. It's equipped with a 2.5-liter V6 engine, which delivers smooth and natural driving without the lag commonly felt in turbocharged cars. In city driving, the fuel consumption is around 11L/100km, and it can drop to about 8L on the highway. While not the most fuel-efficient, it's still acceptable. The FSI direct injection makes acceleration more responsive, especially when starting from traffic lights. This displacement is sufficient for daily use, and maintenance isn't complicated—an oil change and filter replacement cost just a few hundred yuan. When buying a used car, the A6 30FSI has a good reputation, but older models require regular checks on the cooling system and sensors. Overall, the 2.5L size strikes a balance between power and practicality.

I recall the naming history of Audi models, where the 30FSI suffix indicates it is equipped with a 2.5-liter V6 engine. FSI technology is Audi's direct injection system, improving fuel efficiency. The power output is around 190 horsepower, delivering an elegant and smooth driving style. With advancements in automotive technology, similar models have shifted to turbocharging, reducing displacement while maintaining comparable output. When choosing this A6, the 2.5L engine offers good reliability and simple maintenance, making it suitable for owners who prioritize comfort.
