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.
What distinguishes a 35 TFSI from a 40 TFSI?
With the introduction of mid-series 40 TFSI and 40 TFSI S-line versions, which start at $53,900 and $59,400 plus on-road expenses, respectively, AUDI Australia has strengthened its essential Q3 premium small SUV lineup.
The 40 TFSI is positioned above the base 35 TFSI, which has an on-road price of $46,400 plus. It offers a number of extra incentives, such as a larger engine, Audi’s quattro all-wheel-drive system, and a number of other standard features.
The 2.0-liter four-cylinder turbocharged petrol engine in the 40 has more power and torque than the front-drive 35 TFSI’s 110kW/250Nm 1.4-liter turbo-petrol engine, giving it a stronger presence.
The Q3 40 TFSI can accelerate to 100 km/h from a complete stop in 7.8 seconds thanks to a seven-speed automatic transmission that distributes power to all four wheels.
Additionally, it can achieve a combined cycle fuel efficiency of 8.3 liters per 100 km and release 188 grams of CO2 per kilometer.
Due to its distinctive 19-inch alloy wheels and fully body-colored paint finish, the 40 TFSI can be identified from the 35 TFSI.
With its 20-inch Audi Sport alloy wheels, rear window privacy glass, and S-line exterior package, the more costly 40 TFSI S-line goes a step further.
Leather upholstery, dual-zone climate control, ambient lighting, cloth headlining, a 10.1-inch touchscreen MMI navigation and infotainment system, DAB+ digital radio, a six-speaker audio system, a 10.25-inch digital instrument cluster, four USB ports, and Qi wireless phone charging are all included in the high standard cabin specification of the 35 TFSI and 40, respectively.
Along with keyless entry/start, wireless Apple CarPlay, an electronic tailgate with gesture control, an auto-dimming rearview mirror, a multifunction leather-covered steering wheel with shift paddles, and Audi drive select, the new mid-range model also includes these features.
The additional $5500 for the S-line adds exterior improvements as well as S-embossed leather sports seats, stainless-steel sports pedals, brushed aluminum inlays, a larger Virtual Cockpit display (12.3 inches), contrast stitched floor mats, illuminated door sills, a leather-wrapped flat-bottom steering wheel, and a premium 10-speaker audio system.
Autonomous emergency braking with bicycle and pedestrian recognition, lane-departure warning, lane-change warning, rear cross-traffic assist, tyre pressure monitoring, hill-descent control, all-around parking sensors, and a reversing camera are among the safety features on the 40 TFSI.
A 360-degree camera, high-beam assist, park assist, auto-dimming exterior mirrors, and adaptive cruise aid are all included with the S-line model.
With a starting price of $89,900 plus on-roads, the high-performance RS Q3 sits at the top of the Q3 lineup and is more than $30,000 more expensive than the 40 TFSI S-line. It has a 2.5-liter, five-cylinder, 294kW/480Nm engine.
Audi sold 997 units of the Q3 in the first four months of 2020, trailing the category leader, the BMW X1, by just nine units (1006).
What makes 40 TFSI and 45 TFSI different?
The new, less expensive 40 TFSI model has 184 horsepower, but the price of the 228-hp 45 TFSI model increases by $1400. For the 2021 Q3 lineup, Audi is introducing a new base model. The 40 TFSI has a 2.0-liter inline-four turbocharged engine that is less potent than the 45 TFSI’s current engine.
What do the numbers 35 and 40 on an Audi mean?
Each of the numerals will be placed next to any existing TFSI, TDI, G-tron, or E-tron badges. You may be able to somewhat understand the complex new nomenclature by referring to the chart below: 30 = 109-128 hp (81-96 kW) 35 = 147-160 horsepower (110-120 kW) 40 = 167-201 hp (125-150 kW)
Is TFSI superior to TDI?
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?
