“The cetane rating of HVO is roughly 30% higher, increasing the engines’ combustibility. When cold starting, the advantages of this are most obvious. Before approving, we conducted special validation runs to examine the effects on various components, performance, and exhaust emissions “According to Matthias Schober, who oversees powertrain development for Audi’s V-TFSI, TDI, and PHEV vehicles.
HVO fuel is created from leftovers and waste products, such as food industry frying oil and agricultural residues. These oils can be transformed into aliphatic hydrocarbons through the process of hydrogenation, making them suitable for use in motor vehicles. These can be combined with standard diesel fuels or used in place of them.
As of mid-February of this year, only the A4, A5, A6, A7, A8, Q7, and Q8 models will be produced; new Q5 diesel versions will begin to be produced in early March. Therefore, even if they are relatively new, this fuel won’t be officially compatible with earlier V6 Audi cars.
Other Audi diesel vehicles, notably the four-cylinder A3, Q2, and Q3 in Europe, have previously been constructed to accept HVO. Additionally, according to Audi, HVO has been available for the A4, A5, A6, A7, and Q5 models in Italy, Sweden, and Denmark since mid-2021.

Does Audi have a diesel option?
The 45 TFSI is the only model of the brand-new Audi A6 available in our market, which just went on sale in India. An A6 with the designation 45 TFSI has a 2.0-liter turbo-petrol engine with 245 horsepower and 370 pound-feet of torque. While the 45 TFSI’s performance numbers bring it on par with petrol rivals like the BMW 530i (252 hp) and Jaguar XF 25t (250 hp), and even give it a lead over the Mercedes-Benz E200 (197 hp), a diesel engine is absent from the A6 lineup. A6 diesel, however, won’t be available anytime soon as the automaker is still assessing its diesel strategy for India.
New versions of the Audi A8, Q8, and Q3 will soon be available, while an improved Q7 will follow in 2020.
Audi will adapt its petrol engines to BS6 specifications, but when the BS6 requirements take effect on April 1, 2020, it’s possible that certain existing models’ diesel versions will be discontinued, at least temporarily. Given that diesels account for the majority of sales in the premium market, this might hurt Audi’s volume. Although gasoline sales now make up a larger portion of total sales, diesels still account for 65% of Audi India’s sales. Mercedes has already begun releasing cars with BS6-compliant diesel engines, one of the main competitors to Audi.
Audi is considering electrification as well and is flexible in this regard. “We have the plug-in hybrid technology and are testing it. We can experience the transition from gas to gas-hybrid to electric vehicles. We have these on the table and are in contact with the administrative center about them.

Are Audi cars gasoline or diesel?
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 stopped producing TDI when?
A stop-sale letter was given to dealers on Tuesday and states that five of Audi’s six diesel models are no longer available for sale.
According to the notification Automotive News received, sales of the 20132015 Q7, 20142016 A6, A7, A8, A8L, and Q5 Audi TDI cars are prohibited. An official statement has not yet been published by the company. The vehicles go beyond the 2016 A6, A7, A8, A8L, and Q5, which were the only ones mentioned in a second EPA violation notice to the Volkswagen Group on Monday. The warning did not mention the new 20152016 A3 TDI or any A3 TDI automobiles from the 20092013 generation. Tuesday also saw the suspension of the 20142016 Porsche Cayenne Diesel and the start of a second inquiry by Volkswagen into the fuel economy of 800,000 additional vehicles.
For the 2014 model year, Audi unveiled a selection of automobiles powered by TDI engines and staged this promotional photo in Washington, D.C.
Audi A4: Does it come in diesel?
Audi’s diesel version is, in fact, offered in India. Audi A4 35 TDI Premium, Audi A4 35 TDI Premium Sport, Audi A4 2.0 TDI (177 PS)-Diesel, and Audi A4 3.0 TDI Quattro-Diesel are the models that are offered.
There are five different versions of the Audi A4 saloon, four of which are diesel-powered. The entry-level Audi A4 1.8 TFSI Multitronic trim is the sole petrol model offered in the sedan’s lineup. The A4 2.0 TDI trim is the next one, followed by the A4 2.0 TDI (177 PS) model, the A4 TDI Premium Sport Limited edition, and the top-of-the-line A4 3.0 TDI Quattro.
The 2.0 liter TDI diesel engine and the 3.0 liter Quattro diesel engine are the two diesel engine options for the Audi A4. While its 3.0 Liter, Quattro diesel engine produces astounding 241 bhp of maximum power with 500 Nm of maximum torque, its 2.0 Liter, TDI diesel engine only produces 177 Bhp of maximum power with 380 Nm of maximum torque.
I had a few opportunities to operate this vehicle. One of my cousins has a vehicle with a 3.0L diesel engine and Audi’s renowned Quattro system. This car has great power, pick-up, and performance. While the vehicle’s top speed is 250 kmph, it can easily reach a speed of 1100 kmph in under 6 seconds.
Without a doubt, the Audi A4 diesel variants have excellent overall performance. Its 3.0 Liter Quattro technology diesel engine variant in particular. It boasts a seven-speed S tronic automatic transmission system gearbox, which provides the most comfort when driving without sacrificing the vehicle’s performance. Simply depress the accelerator to experience the power; its acceleration and pick-up are incredible.

When did Audi start producing TDI?
Audi unveiled a brand-new engine in 1989 at the IAA Frankfurt Motor Show. This innovative engine, a 2.5 liter five cylinder direct injection turbocharged diesel engine with fully electronic engine management, was the first of its kind and the first in a long line of ‘TDI’ engines. Due in part to a distributor-type fuel injection pump that could generate a maximum pressure of 13,053 PSI (900 bar), which aided in more effective burning of the diesel fuel, it initially produced 120 horsepower and 195 lb-ft of torque when it was installed in the Audi 100. The output of the A6 finally increased to 140 horsepower after additional work on the injection pump and exhaust gas recirculation.
The Audi 80 and later the Audi 100 were the first vehicles to use the 1.9 liter (and first four cylinder) TDI engine. This engine produced 90 horsepower and 134 lb-ft of torque at a fuel injection pressure of up to 13,779 PSI (950 bar). With the addition of a variable turbine geometry (VTG) turbocharger in 1995, the engine’s power increased to 110 horsepower and 166 lb-ft of torque. The A3, A4, and A6 all utilized this updated engine. Pump-nozzle fuel injection and water-cooled exhaust gas recirculation were added to the 1.9 TDI in 1999. Power and torque were up to 115 hp and 210 lb-ft, while fuel injection pressure reached 29,733 PSI (2,050 bar). Later, variants with 100 horsepower and 130 horsepower would also be offered.
Using a new double overhead camshaft engine head with four valves per cylinder, the 1.9 liter TDI was increased to two liters in 2003. The output was 236 lb-ft of torque and 140 horsepower. A new two-liter TDI model with common rail fuel injection and piezo injectors was released in 2007. Although the maximum fuel injection pressure decreased to 26,107 PSI (1,800 bar), output increased to 143 horsepower (torque remained the same at 236 lb-ft), and the redline was lifted to 5,000 RPM. A variant of this engine was installed in some Audi TTS models in 2008; it produced 170 horsepower and 258 lb-ft of torque, reached its redline at 5,400 RPM, and accelerated the sports vehicle to 62 mph in just 7.5 seconds.
The two-liter TDI was updated in 2009 with a new model that produced 136 horsepower and 236 lb-ft of torque while also enhancing fuel efficiency and reducing pollution. A tweaked version of the two liter was made available in several Audi vehicles starting in 2012. The engine now produces 150 horsepower and 251 lb-ft of torque after the fuel injection pressure was raised once more to 29,008 PSI (2000 bar).
A new 2.5 liter TDI was introduced by Audi in 1997 and was intended to be used in the A4, A6, allroad, and A8. This time, the 2.5 liter engine had a V6 and a VTG turbocharger with four valves per cylinder. The engine initially produced 150 horsepower and 229 lb-ft of torque before increasing to 180 horsepower when the direct injection was operating at 21,756 psi (1,500 bar).
With the 3.0 TDI, a new generation of V-engines was introduced in 2004. These engines all had a 90 degree bank angle, 90 mm cylinder spacing, and a chain drive on the back of the engine. This V6 engine had a vermicular graphite cast-iron block, piezo inline injectors, and a maximum injection pressure of 23,206 psi (1,600 bar). At introduction, there were three models that produced 204, 224, and 233 horsepower, respectively. The 3.0 TDI was quickly followed by the 2.7 TDI in the A4, A5, and A6, which had a slightly shorter stroke and a smaller displacement. 180 horsepower and 280 lb-ft of torque were produced at first, then later, 190 horsepower.
The 3.0 TDI clean diesel with an extremely low emission technology was introduced in 2008. This engine met all US emission regulations and the Euro 6 restrictions (which wouldn’t take effect for several more years). New combustion chamber sensors were added, and the exhaust gas recirculation system and Common Rail fuel injection (now up to 29,008 PSI or 2,000 bar) were rebuilt. AdBlue was injected into a DeNox catalytic converter to reduce the majority of nitrogen oxides. The engine produced 406 lb-ft of torque and 240 horsepower despite being cleaner than before.
A new crankshaft, connecting rods, pistons, and cylinder heads were added to the 3.0 TDI in 2010 to save weight (the entire engine was 55 lbs lighter than the previous model), lower friction, and boost efficiency. The maximum fuel injection pressure decreased to 26,107 psi (1,800 bar), however the maximum power and torque stayed at 250 horsepower and 406 lb-ft, respectively.
The 3.0 TDI Biturbo, which has two inline turbochargers, was introduced in 2011. The smaller variable turbine geometry turbo performs the most of the work at lower RPMs. Above around 2,500 RPM, the larger turbo begins to perform the majority of the work, and at approximately 3,500 to 4,000 RPM, the smaller turbo is totally bypassed. With the aid of two turbochargers and a fuel pressure increase to 29,008 PSI (2,000 bar), this engine is capable of producing 313 horsepower and 406 lb-ft of torque.
The A7 Sportback debuted the newest V6 TDI in 2014. Another 3.0 TDI, this one features modifications like new cylinder heads, a VTG turbocharger, and an oil pump. Depending on the variant, power is 218 horsepower and 295 lb-ft or 272 horsepower and 428 lb-ft due to the significant reduction in internal friction.
With a 3.3-liter displacement, four overhead camshafts, 32 valves, and two variable turbine geometry turbochargers, Audi unveiled their first V8 TDI in 1999. Available in the A8, this engine was Audi’s first to utilise common rail injection, producing 225 hp and 354 lb-ft of torque at pressures of up to 19,580 PSI or 1,350 bar. A four-liter TDI with an updated common-rail fuel injection system that included new seven-hole nozzles and increased the maximum pressure to 23,206 PSI was introduced in 2003. (1600 bar). Up to 275 horsepower and 479 lb-ft of torque were available.
The four liter engine was replaced in 2005 with a 4.2 liter TDI. Output would later rise to 340 horsepower in the Q7 and 385 horsepower in the A8, from its initial 326 horsepower and 479 lb-ft of torque. Along with being quite light, the V8 only weighed about 550 lbs. With the addition of piezo injectors, the most recent 4.2 TDI model’s maximum fuel injection pressure was increased to 29,008 PSI (2,000 bar) in 2014. The engine produces 385 horsepower and 627 lb-ft of torque with its two VTG turbochargers operating at up to 24.7 pounds of boost (1.7 bar).
The 2008 Q7 had Audi’s most potent TDI engine to date. The flawlessly balanced V12, which had a six-liter displacement and was related to the engine in Audi’s R10 TDI race vehicle, produced an astounding 500 horsepower and an even more astounding 738 lb-ft of torque, again in part because of the maximum 29,008 PSI (2,000 bar) direct injection pressure. The 5500+ weight SUV was able to reach 62 mph in about 5.5 seconds using all of its power.
Additionally, Audi has produced a number of other (mainly smaller) TDIs, including various 1.2, 1.4, and 1.6 liter engines, although the majority of these have never been offered in North America. Audi has demonstrated that the TDI engine is quite capable through their results at the 24 Hours of Le Mans, beginning with the R10 TDI in 2006 and later with the R15 TDI and R18 TDI. Many of the TDIs share comparable technology (after already proving that their gasoline engines were no slouches either with their R8 LMP race cars of the early 2000s).
