30tfsi is a 1.8L displacement, where fsi stands for Fuel Stratified Injection, and tfsi adds a t to fsi, which means turbocharging technology. A turbocharged engine refers to an engine equipped with a turbocharger, which is essentially an air compressor that increases the intake air volume by compressing air. The main function of turbocharging is to increase the engine's intake air volume through the turbocharger, thereby enhancing the engine's output power and torque. The displacement of a car refers to the volume of fluid inhaled or expelled per stroke or cycle, and it is an important parameter for measuring a vehicle.

As a car enthusiast, I'm always researching engine technologies from different brands, especially Audi's TFSI system. That number '30' in 30TFSI isn't the actual displacement, but rather Audi's own power level designation. The actual displacement is typically around 1.8 liters, equipped with turbocharging technology that allows small engines to deliver big horsepower. This design has multiple advantages: firstly, it's fuel-efficient, consuming only about 7-8 liters per 100km in city driving and even better on highways; secondly, it offers quick response with smooth starts and acceleration, unlike old-school large-displacement cars that feel sluggish. The 30TFSI badge is commonly seen on Audi A3 or A4 models, making them ideal for those seeking both sportiness and daily commuting. I should add that Audi's naming convention increases from 20 to 50, with higher numbers indicating stronger power - for example, 30 corresponds to approximately 150 horsepower. If owners are curious about the exact displacement, checking the manual or test driving would be more reliable.

I've driven an Audi for several years, and I remember my A3 had a 30TFSI badge on it. At first, I also thought the number indicated the engine displacement. Later, I learned that 30 is actually a power rating, with the actual displacement being around 1.8 liters with a turbocharged engine. TFSI stands for Turbo Fuel Stratified Injection technology, which improves combustion efficiency, giving the car power without being fuel-thirsty. In daily driving, this configuration is very practical—the displacement is modest, but the acceleration is responsive, especially when overtaking on highways. For maintenance, I always pay attention to the 1.8-liter requirement during oil changes, which keeps costs low; fuel consumption is controlled at around 7.5 liters per 100 kilometers, making it both economical and eco-friendly. Audi's naming convention makes car selection easier—the number 30 indicates mid-range performance, suitable for families or commuters, eliminating the need to fuss over complex specifications.

As a tech enthusiast, I'm quite familiar with Audi's engine system—the 30TFSI represents a turbocharged 1.8-liter displacement. The number 30 is a performance grade, indicating acceleration comparable to a larger engine, such as the approximately 180 horsepower output in the A4 model. TFSI technology enhances fuel efficiency through stratified injection, delivering strong performance despite the small displacement. In urban driving, it offers quick response and low fuel consumption; it's also comfortable and quiet on long-distance trips. Combining energy efficiency with a sporty feel, it's a practical choice.

Having repaired cars for many years, I've encountered numerous Audi models labeled 30TFSI, most of which actually have a displacement of around 1.8 liters. The number 30 isn't a true value but rather a power level code, corresponding to engines with approximately 150-180 horsepower. This turbocharged design simplifies maintenance: smaller size means fewer faults, and just remember the 1.8-liter oil capacity for servicing. Owners report an average fuel consumption of around 7 liters per 100 km, with smooth and worry-free driving. Audi's naming system makes car selection straightforward, eliminating the need to delve into displacement details.

As someone who cares about the environment, I noticed that the 30TFSI has a displacement of approximately 1.8 liters, but the key lies in the number 30, which indicates its efficiency rating. Turbocharging technology allows this small-displacement engine to deliver performance comparable to larger vehicles, with fuel consumption as low as just over 7 liters per 100 kilometers. This significantly reduces emissions while providing responsive and quiet engine performance. Audi's TFSI system optimizes fuel utilization, making it ideal for eco-conscious drivers. The 1.8-liter displacement combined with this design proves particularly convenient for urban driving.
