The turbo fuel stratified injection engine is Audi’s most often used engine (TFSI). When gasoline is pressure-injected into the engine’s combustion chamber to provide an immediate charge, this is referred to as the turbo aspect.
The TFSI engines’ direct fuel injection combined with turbo or supercharging technology results in a powerful ride while using up to 15% less gasoline than a V6 engine.
So how does it function? Direct fuel injection improves efficiency and responsiveness by eliminating heat from the intake air, which raises compression and eliminates knock.

Do Audi TFSI engines work well?
Make sure you receive the engine you desire by understanding what the labels on your Audi imply. Naturally, the majority of auto dealers will prominently designate vehicles with their fuel type, but understanding the manufacturer’s own shorthand might be useful nonetheless.
What does TFSI stand for?
Every gasoline-powered Audi vehicle has the TFSI badge, whereas TDI is the emblem for diesel vehicles. The acronym TFSI, which stands for “Turbocharged Fuel Stratified Injection,” designates a turbocharged gasoline engine. Audi used to sell ‘FSI’ engines, which lacked turbochargers, for about 15 to 20 years.
Since the fall of 2017, Audi cars frequently have a number before the TFSI or TDI logo. The power of the car is indicated by these two numerals, which range from 25 to 70. Audi claims that the number is there to make it simpler to compare gasoline or diesel, hybrid, and electric vehicles. It has nothing to do with the size of the engine or the amount of horsepower you get. When ordering a new Audi, you can choose to have the badge removed if you’d like.
TFSI vs TSI
The only brand in the Volkswagen Group to utilize ‘TFSI’ emblems is Audi; the majority of the other brands use ‘TSI’. As engines are frequently transferred between brands without any alterations, there tends to be no distinction between the two in more recent vehicles.
TFSI was utilized on belt-driven engines and TSI on chain-driven engines in some earlier cars, but it doesn’t seem like that’s the case now.
Audi TFSI e engines
An Audi TFSI e engine isn’t just a regular petrol engine despite the small “e” that is added. You’ll notice it if you’re gazing at the Audi Q5 TFSI e or another of the brand’s numerous plug-in hybrid (PHEV) vehicles because it denotes that the vehicle is a PHEV.
In this case, a battery, one or more electric motors, and a gasoline engine are combined. Typically, a fully charged battery will provide at least 30 miles of electric range, improving fuel economy and lowering operating expenses.
Audi TFSI engine problems
The Audi TFSI engine has generally proven to be dependable, but like with all engines, proper and appropriate maintenance is the secret to longevity. Higher-than-average oil consumption in pre-2012 TFSI engines could be unimportant or, in rare situations, a hint that the engine’s piston rings are perhaps worn. Although recirculation valves and injectors appear to be components to watch out for, TFSI and TSI engines are generally known for their dependability.
Audi TFSI or TDI: Which is superior?
A 2.0ltr Q5 S Line Plus in Mythos Black with a black pack and titanium wheels, as well as a few additional extras to make life with it a little nicer, is pretty much what we’ve decided to go with. Our Discovery 3 has been with us for seven years, and we typically retain our cars for at least five years. We would rather buy a car outright than finance it through a PCP or lease.
Which should I choose: the tdi or the tfsi? We travel 6k miles year on average, about 30% of which is within the city and the rest is spent on lengthy trips with the kids and the annual family vacation. Normally, getting a diesel engine would cost more, but in this case, the price was the same for both. The tdi’s obvious advantage is better economy, although Audi’s official statistics show that it is slower than the tfsi. We wouldn’t travel far enough to benefit from diesel, so if the tfsi were less expensive to purchase, it would be a no-brainer.
Beyond the obvious advantages of performance over economy, what are the disadvantages of each engine?
TFSIis it a turbo?
The first turbocharged direct injection engine in the world is the TFSI (Turbo fuel stratified injection). This technology offers increased fuel efficiency and improved engine responsiveness in addition to higher power output and lower emissions.
Is TFSI short for turbocharged?
The idea of combining direct fuel injection, also known as FSI by Audi, with a supercharger or a turbocharger is known as TFSI, short for Turbocharged Fuel Stratified Injection.

What distinguishes TSI from TFSI?
What actually separates the TSI and TFSI, then? The gist of the response is that there aren’t many differences, but there are a few. To begin with, TSI stands for “Fuel Stratified Injection and Turbo Stratified Injection are both abbreviations for FSI. Both Volkswagen and Audi direct fuel injection engines fall under this. Unbelievably, TFSI is an acronym for “Stratified Turbo Fuel Injection.
Diesel versus gasoline, which Audi engine is superior?
It is evident that supporting one model practically cannot be done. Both the diesel and gasoline versions of the Audi A4 have advantages and disadvantages. You are entirely responsible for deciding whether to use a gasoline or diesel mill. There are several things that affect how decisions are made. Please keep in mind that diesel vehicles have cheap operating costs and reduced maintenance requirements compared to gasoline vehicles. Because diesel engines must handle greater pressure than a typical petrol engine due to higher combustion pressure, they require routine maintenance such as fluid changes. Simply said, diesel requires more maintenance and has lower running costs, and vice versa. Oh, the petrol one, this is real.
It should be remembered that a diesel variation has more power and torque than a petrol run variant when comparing gasoline and diesel run variants.
174.33 horsepower at 4200 rpm and 380 Nm at 1750 2500 rpm as opposed to 167 bhp at 380 06 200 rpm and 320 Nm at 140 03 700 rpm. Additionally, diesel outperforms petrol run trims handsomely in terms of mileage. Diesel vehicles achieve 16.55 kph in the city and 17.11 kph on the highway, compared to 12.32 kph in the city and 15.64 kph on the highway for gasoline vehicles.
The decision to choose an Audi A4 with a diesel or gasoline engine depends on the priorities of the buyer. In comparison to its petrol-powered counterpart, the diesel model offers better engine power and mileage. Additionally, a diesel-powered model can carry a bigger load because to the higher engine power (passenger and cargo). However, the engine is more noisy, more combustible, and expensive to maintain. On the other hand, the petrol version is lightweight and requires little upkeep.
Which of the outstanding sedans, the Audi A4 petrol or diesel, you choose will depend on your own preferences. You may also make a choice based on the needs you have for running. You can choose the diesel version if your daily commute is more than 60 to 70 km, but if it’s only 20 to 50 km, you should choose the petrol version. Both engines get about identical mileage. Although the power output of the diesel and gasoline engines is nearly equal, the diesel variant offers more torque.
If we choose one of these two, it would be unfair to the other. Diesel and gasoline each have advantages and disadvantages. For instance, the diesel engine claims to require high maintenance because it puts more strain on the engine yet is great for longer trips and provides superb low end torque and power while operating at low cost. On the other side, gasoline is better for city driving since it provides you more power and allows you to drive faster, but it has less maintenance and a high running cost because of the price of the fuel.

Is the 2.0 TFSI trustworthy?
Overall, we’d say “yeah”! It is obvious that the 2.0 TFSI engine must be at least somewhat dependable because it has been utilized in numerous models across numerous continents for many years.
Another question is whether it can be trusted in comparison to its rivals. Over 50,000 warranty direct policies are used to gather the data for the Warranty Index.
There are only 2 Audi vehicles on the top 100 list at the moment. No specs are provided, although both of these are compatible with the 2.0 TFSI engine. Additionally, the TT, which ranks 44th most trustworthy, is the highest-ranking Audi.
The 2.0 TFSI engine is often available in Audi’s medium- to large-sized vehicles, including the A3, A4, A5, and A6. These automobiles compete directly with models from the Mercedes C and E Class and the BMW saloon lineup.
What does Audi’s S line refer to?
The highest-spec trim, Audi S-Line, is available for all models, from the A1 to the A8, and it adds a variety of additional amenities.
In an Audi, what does quattro mean?
Given that the word “quattro” is associated with Audi’s all-wheel drive system, the Italian word for “four” seems fitting. However, it wasn’t always like this. Actually a separate vehicle, the Audi Quattro (yep, with a capital Q) debuted in 1980.
In addition to being the first Audi vehicle with AWD, Quattro also entered competitive rally racing as a result of a regulation modification that made the drive system acceptable. Four world championships were won by the car for the company in the early 1980s. After 40 years, the term Quattro now specifically refers to the automaker’s AWD technology, which is offered on the majority of its portfolio and is officially trademarked as quattro in lowercase.
What does a winning rally car’s drive system have to do with what the typical consumer should care about or even want? Of course, for the same factors that made the Audi Quattro successful in racing.
What in an Audi does S tronic mean?
The S tronic combines the practicality of a contemporary automatic transmission with the effectiveness and sportiness of a traditional manual gearbox. Rapid shifting is possible with almost no audible interruption of the power flow thanks to the dual-clutch transmission. Dynamically and smoothly, the car accelerates.
Two multi-plate clutches and two sub-transmissions make up the 7-speed S tronic. Although both of these are constantly in use, only one of them is ever being powered by the engine. For instance, the second transmission section is already in fourth gear while the driver accelerates in third gear. By switching the clutches, one opens and the other closes, shifting the gears is accomplished. It just takes a few hundredths of a second to switch gears, with hardly any loss of power. The car passes by so swiftly and smoothly that the driver hardly notices it.
The two unique oil systems of the 7-speed S tronic are one of its distinguishing qualities. Gear sets, the center differential, and the front-axle differential are all lubricated independently, while the dual clutch, mechatronics module, and oil pump are all supplied by their own oil circuits. The benefit of this is that there is no need to compromise on the lubricant being used, ensuring a sufficient amount of oil for all components.
S tronic combines the practicality of a modern automatic transmission with the effectiveness and sportiness of a traditional manual transmission.
With the 7-speed S tronic, the driver has the option of manually shifting gears or letting the transmission do it for them. In manual mode, he chooses when to shift gear and does so by pulling the selector lever or using the paddles on the steering wheel. With the Drive program (D) and Sport program, he can alter the way the transmission behaves when shifting gears in automatic mode (S). The efficiency mode can also be chosen in conjunction with Audi drive choose, which is available for various models. This has a modified shift schedule and an energy-saving default configuration. When efficiency mode is engaged, for instance, the car automatically enters coasting mode and keeps moving without any engine braking losses if the driver lifts their foot off the accelerator.
While we put a lot of emphasis on dynamic performance, we also place a high value on efficiency because high efficiency lowers fuel consumption and pollutant emissions.
