New two-digit engine badges from Audi indicate the amount of power each model generates. Make sense of the changes using our explanations.
Audi has introduced a new engine badging method that has some fans baffled. Audi has abandoned the practice of using engine badges to indicate the size or power of the engine in favor of a two-digit system that indicates the amount of power the vehicle is capable of.
Use the chart below to make sense of the numbers since they don’t appear to correspond to the car’s real horsepower figure. By summer 2018, it will be implemented gradually beginning with the release of the new Audi A8 and will apply to all models. These adjustments do not apply to high performance RS vehicles or sporty S versions.

Why does the Audi badge exist?
Let’s start at the very beginning: the Audi brand’s history dates back to the 19th century and includes
Julius Horch The mechanical engineer established his own company, August Horch & Cie, in 1899. Initially, he produced two-cylinder autos, and later, four-cylinder vehicles. He departed the business in 1909 as a result of a disagreement with the board of directors.
Horch then started a new vehicle company that same year. He could not use the name Horch because it was already in use, so he converted his last name into Latin: “Audi. The first vehicle under the new brand hit the streets in 1910. With three victories in a row at the International Austrian Alpine Rally, one of the toughest rallies of the day, between 1912 and 1914, Audi attracted attention.
Four ringsfour brands
Four interlocking rings represented the joining of four Saxony-based automakers: Audi, DKW, Horch, and Wanderer to form Auto Union AG. Here are some quick facts about the history of the current AUDI AG.
What do the new model numbers on Audi cars mean?
Since the end of 2017, Audi has changed the way its models are badged to reflect the power output.
It basically means that the engine size is no longer visible, if you haven’t noticed this before on the back of an Audi. This “litre” badging, e.g. “2.0,” is changed to a number between 25 and 70 that denotes the power output.
This approach, which at first glance may seem complex, was put in place to make it simpler for purchasers to compare the power output of electric and plug-in hybrid vehicles with traditional petrol and diesel ones.
As we’ve mentioned the number badges varies from 25 to 70, depending on the power output, with the number rising in increments of five. The smaller the number, the less power it has, meaning higher numbers have more power. For each number, there is a range of outputs, so if it’s a ’30 TFSI’ that means it can have between 108bhp and 129bhp, for example.
The fuel designation follows. Therefore, if it says TFSI, it’s a petrol engine, and if it says TDI, it’s a diesel engine. A plug-in hybrid will have the designation “TFSI e,” while an all-electric vehicle will have the designation “e-tron.”
It’s time to understand the strength behind that number. The car is identified by the number on the left, along with the corresponding power outputs.
Please be aware that the “RS,” “R,” and “S” versions do not have this branding, though you can request that it be removed at the manufacturer if you don’t like it.
What does a TFSI of 40 mean?
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.
A and S Models
Sedans or hatchbacks are the types of Audi cars that start with the letter A. The size of the car increases as the next number increases. Accordingly, the A3 is Audi’s smallest sedan, while the A8 is their biggest.
The majority of Audi sedans and hatchbacks have a model that starts with the letter S. Sport, denoted by the letter S, refers to a bigger, more potent engine with more horsepower and torque. For instance, the S6 resembles the A6 in terms of look but has an 8-cylinder, 450-horsepower engine as opposed to the A6’s, which has a 6-cylinder, 333-horsepower engine.
Q Models
Q stands for quattro, the renowned all-wheel drive system from Audi. SUVs, crossovers, and wagons that begin with the letter Q always have quattro as standard equipment. The Q3 is the smallest and the Q7 is the largest, just like with Audi cars.
R Models
Roadsters with mid-engines and two seats, like the R8, are performance sports cars. Audi Space Frame, a high strength aluminum frame with integrated panels that is lighter and stronger than conventional steel, serves as the foundation for the body of these vehicles.
RS Models
RS stands for “Rennsport,” which is the German equivalent of “Race-Sport.” The most powerful and high-performing Audi models are called RS models. Audi typically only makes one RS model at a time, and the current RS 7 boasts a staggering 605 horsepower TFSI engine that accelerates from 0 to 60 mph in under 3.3 seconds.
TT Models
The Tourist Trophy, a motorcycle racing competition held on the Isle of Man for more than a century, inspired the naming of TT models, which deviate from the naming convention’s set norms. Compact sports vehicles known as TT variants have transversely mounted turbocharged engines. The TT is offered in the aforementioned S and RS variants.
TFSI stands for what?
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 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)
What distinguishes a 30 TFSI from a 35 TFSI?
The badges on future Audi cars will no longer indicate engine size but rather engine power.
According to Audi, the change is intended to reflect the added performance provided by electrified vehicles, which include hybrids, plug-in hybrids, and completely electric vehicles, and to simplify for purchasers the range’s definition.
The badges on the back of the automobiles will now display a new number between 30 and 70, even if the models’ names themselves won’t change (the Audi Q5 will still be called the Audi Q5, for instance). The power of an automobile’s engine determines what number it receives.
This is how the complete naming scheme is divided down:
- Models with 107-127 horsepower will have a “30” emblem.
- Models with 145-159 horsepower will have the badge “35.”
- Models with 165-198 horsepower will have a “40” badge.
- Models with 223-244 horsepower will have a “45” emblem.
- Models with 278-304 horsepower will have a “50” badge.
- Models with 423-449 horsepower will have a “60” badge.
- Models with 529 horsepower or more will be labeled as “70.”
Although Audi hasn’t released power brackets for those models, it’s anticipated to be used for vehicles with 328-468 horsepower. There will also be a 55-badged range of automobiles. The standard TDI, TFSI, or e-tron badges will still be used to indicate if a car has a diesel, gasoline, or electric powertrain.
What makes 40 TFSI and 45 TFSI different from one another?
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.
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?
TFSI has a twin turbo?
The 4.0-liter V8, which drives the top-of-the-line Audi A8, is at the top of the TFSI mountain. This twin-turbo engine generates 450 horsepower and 325 ft-lbs of torque when mated to an automatic transmission with an 8-speed shiftable.
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.
Which trim levels are there for Audi?
There are three major trim levels used on Audi automobiles. The Premium trim level is the entry level, followed by the Premium plus level and the Prestige trim level, which is the top of the line. Not all trim levels may be provided depending on the model; for instance, the S4, S5, and SQ5 are only available in Premium plus and Prestige, while some of Audi’s higher end vehicles, such the RS 5, S6, S7, and RS 7, are only sold in one trim line.
