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 makes 40 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.
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 distinguishes the Audi 35 and 40?
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.
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.
TFSI: What does it mean?
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)
How can A4 40 and 45 be distinguished from one another?
The A4 is available from Audi in two strengths: 40 and 45. The 40 and 45 both have an all-wheel drive, 12-volt hybrid, turbocharged 2.0-liter four-cylinder engines that produce 201 and 261 horsepower, respectively. The only gearbox option is a seven-speed automatic, even though we would prefer a six-speed manual. The well-equipped A4 45 we drove reached 60 mph in 4.8 seconds, and its automatic transmission changed gears smoothly and quickly. The A4 has a sharp handling balance between precise steering, well-controlled body movements, and good roadholding. Typically, vehicles with such quick responses have to give up ride quality, but the A4 does it with ease. When traveling at slower speeds and on the interstate, the steering sensation, so crucial in a sedan with sports overtones, is muted. However, when you push the car on winding roads, the steering magically becomes pleasantly communicative.
What distinguishes the Audi 40 and 45?
Although it only comes in Komfort trim, the first of the Q5’s three trim levels, it sits next to the Q5 45. The Q5 40 starts at $45,250 at that Komfort level, while the Q5 45 Komfort starts at $48,000. The delivery fee is thus $2,700 for all Q5 variants.
It isn’t offered in the swoopier-styled Q5 Sportback, which is only offered in the top two trim levels and not the Komfort level, but rather just in the normal Q5 lineup.
The 2.0L four-cylinder turbocharged engine in both the 40 and 45 is powered by a 12-volt mild hybrid system, which produces 261 horsepower and 273 lb-ft of torque. The 40 produces 201 horsepower and 236 lb-ft of torque without a mild hybrid and doesn’t require premium fuel. Both have Audi’s Quattro all-wheel drive and a seven-speed automatic transmission.
What distinguishes an Audi A5 40 from an A5 45?
Two turbocharged four-cylinder powertrains for the A5 Sportback in 2022 are available, each using a 12-volt hybrid system. Models with the 40 badge produce 201 horsepower, while those with the 45 badge produce 261 horsepower. All A5 Sportbacks come with a seven-speed automatic transmission and all-wheel drive as standard equipment.
What model of Audi do I own?
The front of the engine block on the driver’s side has the engine code. The engine code could also be written on a sticker that is fastened to the cylinder head. The numerals, however, are increasingly difficult to read with time.
What does 30 on an Audi 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 system, which at first glance may seem confusing, was put in place to make it simpler for buyers to compare the power output of electric and plug-in hybrid vehicles with traditional petrol and diesel models.
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.
