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.

What does TFSI on the Audi TT mean?
The TFSI engine is found in numerous new Audi automobiles. 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.
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.
Is TFSI preferable to TSI?
Conclusion: Although the two engines are quite similar, the TSI replaced the Turbo FSI and might have experienced more issues. Although these engines are not the most dependable, if they are properly maintained, we have seen both of them survive longer than 200,000 miles.
About Trey
I have a passion for Volkswagen and Audi vehicles and spend my weekends working on them. I also appreciate assisting others by offering insightful and correct knowledge in the field of automobiles. I’ve worked in the automotive sector for at least ten years, and I make it a point to never stop learning new things. I hope that my posts reflect this passion and help the readers.
Is TDI superior to TFSI?
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?
Does a girl drive an Audi TT?
It’s a pretty feminine car, the Audi TT. Its size, dinkyness, and low seating position are akin to the best roadsters and coupes. It may be a little roadster or coupe, but is it the best that money can buy?
While significantly less expensive than an Audi TT, the Mazda MX-5 has much less power. Although the Mercedes SLK may have a prettier appearance than the Audi TT, an all-wheel drive variant is not available.
To find out if the Audi TT is the vehicle to replace your Nissan Micra with, let’s take a closer look at it.
The TT from Audi is stunning. It has significantly more aesthetic appeal than the previous bubble-shaped model, and both the roadster and the coupe versions have a noticeable presence on the road. The Audi TT Black Edition 2.0 TDI, which combines efficiency and speed, is my favorite model. The front grill, window accents, and alloy wheels on that are all glossy black. Standard on Sport models are 17-inch alloy wheels, while S Line trim adds sportier, lower-profile 17-inch wheels. Both vehicles are gorgeous, but the S Line variant has sportier bumpers and a sportier interior.
There is significant performance available in every Audi TT now on the road. There is a selection of engines, including a 1.8 TFSI with 160 PS, a 2.0 TFSI with 211 PS, and a 2.0 TDI with 170 PS and significantly greater torque than its petrol rivals. The 2.0 TDI, which is the exact same engine as the Golf GTD, is my favorite. Its mid-range grunt is amazing, and when combined with the TT’s low profile, it makes for a lot of fun. In addition, the TT TDI is significantly more fuel-efficient on lengthy trips than TFSI variants, making it a useful tool for businesswomen. All engines come with a fast, gorgeous 6-speed manual transmission, but the S Tronic is excellent for the laid-back cruiser. The TT is quiet at highway speeds and does an excellent job of absorbing all the bad roads you’ll encounter.
The cabin of the Audi TT is the prettiest of any sub-$30,000 vehicle on the road. The craftsmanship is exquisite, and everything has a delicate touch. All TTs come with leather or alcantra seats as standard equipment, but full leather is an additional 560. The interior has stylish chrome and aluminum accents, and the S Line grade adds firmer seats, a flat-bottomed steering wheel, and lots of S Line emblems. Due to the smart suspension and high-quality tyres, the interior is a pleasant place to be on long trips, and the driver’s position is great thanks to many rake and reach adjustments.
As I previously stated, the 2.0 TDI is my favorite model in the TT lineup. It only comes with all-wheel drive and has a combined mileage of 53.3 mpg. On a combined cycle, the 1.8 TFSI will deliver 44.1 mpg, while the 2.0 TFSI will deliver 42.8 mpg. All engine configurations are fuel-efficient, but for shorter trips, gasoline engines will perform better while TDIs are excellent for longer trips. Pick the engine that works best for the majority of your driving.
The Audi TT Coupe is available in the following tiers: TTS Coupe, TT RS Coupe, TT Coupe Sport, TT Coupe Sport S Line, and TT Coupe Sport Black Edition. There are three versions of the Audi TT Roadster: the TT, TTS, and TT RS. The majority of consumers will choose the reasonably priced entry-level TT models, but for those looking for supercar-like performance, the TTRS is impossible to ignore. Additionally, a variety of features, such heated seats, are available as extras.
The Audi TT is a unique, elegant, and entertaining car to drive that retains its value well. The TT looks terrific even in base Sport trim, and the Black Edition is the most athletic car you can buy without purchasing a TTS or TTRS. When driving, the TT is swift and comfortable, and all of its engines perform well. For the businesswoman who commutes across the nation, I would choose the 2.0 TDI, which provides 90% of the thrills of a gasoline vehicle while having much lower operating costs. The 2.0 TFSI will do the thing for women who adore smoking small lads and driving fast in their hot hatchbacks, and it also has a very good soundtrack.
When purchasing brand-new, be sure to choose your extras wisely as this will enable you to negotiate a lower price at a later date.
