AUDI A4 is a middle-class car with a longitudinal engine, front-wheel drive or all-wheel drive. It is the successor to the Audi 80, produced in 1986-1994.
The premiere of the new Audi A4 lineup took place in October 1994, and mass production began in November. The body has acquired a more rapid shape with a rounded roof profile characteristic of the new VW-Audi style. The interior trim is just the same home comfort.
Visibility is excellent, while the highest requirements for the passive safety of the car are met: the central pillars hold a side impact well (since October 1996, all models are equipped as standard with not only two front, but also two side airbags, one on each side). In general, this model made a more solid impression, which finally allowed the Audi A4 to become a full-fledged competitor in the circle of prestigious compact models (such as the BMW 3-er and Mercedes-Benz C-class.) segment D. The latest developments of Volkswagen AG in the field of safety and technology (as well as a global production savings program) made it possible to create the Audi A4 on a unified B5 platform, which is also intended for other concern models, such as the WV Passat IV.
Initially, six versions of the 4-door sedan were introduced with different gasoline engines: in-line four-cylinder - 1.6-liter 101-horsepower (ADP), 1.8-liter five-valve per cylinder (125 hp - ADR) and turbocharged (150 hp - AEB); six-cylinder V-shaped - 2.6-liter V6 (ABC - 174 hp) and 2.8-liter (AAH - 174 hp). All these engines, except for the “weakest” 1.6-liter, were also installed on the all-wheel drive version of the Quattro, the production of which was launched without any pause in the same year, 1994. In addition to such powerful and frisky "Otto-motors", the A4 became famous for its no less frisky in-line 1.9-liter TDI turbodiesels with direct injection, first with 90 hp (1Z / AHU), and a year later with 110 hp (AFN) with variable turbocharger geometry. The latter, by the way, was the most economical in its class - fuel consumption in the urban cycle per 100 km of run is only 6.9 liters! Traction characteristics of all used engines are impressive. On petrol models, it is possible to install a Tiptronic automatic transmission, which allows you to shift gears in manual mode, thereby active drivers can fully realize their driving skills.
The galvanized body of the Audi A4 is not afraid of corrosion, in any case, the company gives a ten-year warranty on it. In September 1995, power windows on the front doors became standard, but sunroofs were still made to order. Two months later, in November, the premiere of the Avant station wagon took place with the same range of engines as the sedan, with the exception, again, of the weakest 1.6-liter gasoline. The trunk volume of the station wagon varies from 390 to 1250 liters, which, although not much, is quite acceptable for station wagons for outdoor activities, in the market niche of which Avant is one of the most popular.
The basic equipment of the car includes: anti-lock braking system with engine traction stabilization system, two airbags, power steering, cruise control system, climate control system, central door locking, alloy wheels, radio with CD changer, power windows, external heated, electric mirrors, dust and pollen filter and other necessary equipment.
After the new 2.8-liter 30-valve V6 appeared in April 1996 with 193 hp. (ACK), the number of base models was 37, including the all-wheel drive Quattro models, famous for their excellent tenacity and stability on slippery roads, although the front-wheel drive versions are not inferior to them, far ahead of many all-wheel drive models of competitors.
Sporty all-wheel drive model S4 with a 2.7-liter engine equipped with two turbocharging systems, five valves per cylinder and four camshafts, this engine develops a maximum power of 265 hp. at 5800 rpm. The high torque of 400 Nm remains constant over a wide range of 1850 - 4600 rpm. S4, just like the “charged” station wagon S4 Avant that appeared a year later, is equipped exclusively with all-wheel drive. The sedan accelerates to hundreds in 5.6 seconds, Avant in 5.7 seconds. In fact, "S4" is a product of factory tuning. Designed in a sporty style, the salon has a full range of equipment up to climate control.
The suspension of these cars is characterized by a sporty setting: front and rear there are transverse levers (rear - double), as well as anti-roll bars. The Audi S4 Avant is in high demand, and it doesn't have too many competitors.
The success of the A4 in the International Super Tour in 1996, 7 out of 7 victories in the European, South African and Australian championships confirm the high quality of the car and its sporty character. One of the most titled and prestigious cars in the world, the Audi A4 is a modern alternative to the conservative high class car.
In the autumn of 1999, the premiere of the Audi RS4 took place, which immediately won the title of the most powerful serial station wagon in the world. A modest-looking station wagon has the temperament of a supercar. Its 2.7-liter twin-turbocharged V6 develops 380 horsepower! This power accelerates the car to 100 km / h in just 4.9 seconds. As befits exotic sports cars, these cars drop dramatically in resale value—at least half the price of a new car.
At the beginning of 2000, two new power units appeared: a turbocharged 1.8-liter gasoline engine with 180 hp. and a 1.9-liter high-torque diesel engine with 115 hp. with high-pressure pump injectors, replacing the previous 110-horsepower diesel engine. As a result, the total number of motors from 90 to 193 hp. reached 9, which, in combination with various transmissions and chassis, made it possible to obtain a very wide range of models for every taste.
In the fall of 2000, the premiere of a new generation of A4 models took place. From the first glance at the new Audi A4, the high level of comfort and quality that meets the requirements of a top-class car is evident. This impression is confirmed by the powerful engines, the unique smoothness of the ride, the automatic air conditioning system, as well as the high level of safety and increased body strength. The A4 has already managed to earn worldwide recognition: 2001 brought this car six honorary international awards, including Goldenes Lenkrad (Golden Wheel), and readers of Auto Motor und Sport magazine (Germany) recognized the Audi A4 as the best car of the middle class in 2002.
The appearance of the second-generation Audi A4 is in many ways reminiscent of the larger A6 and even the flagship of the company's lineup - the Audi A8. Unlike the first generation model, the new machine is 69mm longer, 33mm wider and 13mm taller. The first to appear were cars with a sedan body, which has a rather low coefficient of aerodynamic drag Cx, for the new model it is only 0.28.
If you look at the A4 sedan from the outside, you can assume that its trunk is quite small. In fact, this is a "visual deception" of designers who tried to make the car lean. In reality, the dimensions of the trunk correspond to the class of the car. The body of the car is very durable - this is one of the skates of "Audi". Thanks to galvanization, it steadfastly resists salty winters.
Basic equipment, as such, did not exist. In Europe, when a person ordered a new "A4", after choosing the engine and body type, he saturated the car with a variety of equipment at his own discretion. No wonder dealers called these cars "constructor for the buyer."
Salon "A4" can be decorated in one of three corporate styles. The “Advance” version includes materials and leather trim in “natural” colors, as well as walnut wood inserts. Ambition adds a sporty feel to the interior, with upholstery patterns that are more energetic and leather trim in light faux tones that work well with the aluminum inserts. In the A4 Ambition, you can often find a sporty three-spoke leather-wrapped steering wheel. Finally, the most chic performance is the elite "Ambiente". The cozy and luxurious interior is distinguished by wood inserts of a special texture and an abundance of leather. Even in the cheapest configuration, the interior captivates with the high quality of finishing materials and the accuracy of “fitting” parts. And the most expensive versions are equipped no worse than other models.
The modified car will be equipped with a wide range of petrol and diesel engines, which includes 1.8-liter turbocharged engines; 2.0 and 3.0 liters with 150, 130 and 220 hp respectively, and 1.9 TDI turbodiesels with a power of 131 hp. and 2.5 TDI with 180 hp.
Modifications with engines of 1.8; 2.5 and 3.0 liters, in addition to the usual front-wheel drive, will also be equipped with an all-wheel drive transmission, and a Multitronic gearbox is installed on 2.0 and 3.0 liter models.
In 2001, the A4 Avant station wagon and the A4 Cabrio coupe-cabriolet were released, which will receive a folding hardtop (like the Mercedes-Benz SLK).
A4 Cabrio - dynamic and unique, designed using cutting-edge technologies, equipped with all possible equipment. Its predecessor was in production for about nine years and during this time it has rightfully acquired the status of a "modern classic". The new generation model also has all the hallmarks of a cult car.
Its redesigned body, which is 4.57 m long and 1.77 m wide, inherits the classic elegance of the Audi Cabriolet while emphasizing the brand's sportiness. The convertible top of the new Audi A4 Cabriolet is equipped with an electro-hydraulic drive and a heated rear window as standard. Magnificent noise isolation and excellent adaptability to winter conditions are implied by themselves. Thanks to its sporty yet elegant interior design, which blends perfectly with the dynamic exterior, the Audi A4 Cabriolet is remarkably harmonious. The temperament and unique properties of this car are evident at first sight. Its dynamic, flattened bonnet, refined wedge-shaped body shape and powerful rear end with prominent tailpipes clearly express its sporty character.
These are all hallmarks of Audi design. It is these, combined with the power of engines delivering up to 220 hp, that define the character of the A4 Cabriolet, taking driving pleasure to a whole new level.
In addition, the engine of the Audi A4 Cabriolet is aggregated with a multitronic gearbox. It combines the superior performance of a manual transmission with the convenience of an automatic.
The range of engines is quite extensive. Everyone can find a motor to their liking. The most economical 1.6-liter engine is suitable for phlegmatic drivers. This is followed by a 1.8-liter engine with a capacity of 125 hp. It has central injection and accelerates a heavy car quite easily. The engine of the same volume, but with a turbocharger, has a solid power reserve of 150 hp. Thanks to the low-pressure turbine, it pulls powerfully from low revs. A truly sporty temperament gives the car a 2.8-liter V6 engine with a capacity of 193 hp. Complement the picture of gasoline engines 2.6 l / 150 hp. and 2.4 l / 165 hp
The turbodiesel range consists of two engines. Both have direct fuel injection, an air-to-air intercooler and variable turbine geometry for more low-end performance. Such an advanced design provides noiselessness and temperament at the level of a gasoline engine. Four-cylinder 1.9-liter engine from the TDI series with 110 hp. It has a very moderate fuel consumption - its average value is 5.6 l / 100 km. A more powerful version of the V6 2.5-liter with 150 hp. This motor is very harmonious with the station wagon body, since it is absolutely insensitive to the maximum load of the car.
In 2004, at the auto show in Paris, Audi introduced the updated generation of the A4. It features a redesigned body, upgraded suspension and four new engines. As before, buyers are offered the A4 sedan and the A4 Avant station wagon. The body design is made in the new corporate style of the brand. The completely redesigned front end is complemented by the single trapezoidal grille that is typical of Audi. The headlights received a slight bend in the bottom line. A new bumper appeared at the back, a slightly different solution for the trunk lid and new original two-piece lights. The line of the wheel arches and the horizontal stamping on the body have also changed.
In addition, the chassis of the car was also modernized - the elastokinematics of the suspension was changed, the characteristics of shock absorbers and springs were improved, and some of the components and parts were borrowed from the Audi A6 and the Audi S4 modification. The sporty yet comfortable dynamic suspension makes driving the Audi A4 a real pleasure.
Advanced technical solutions, impressive styling and the traditional Audi highest quality interior trim will satisfy even the most demanding customer. Of the changes in the interior, one can note a new steering wheel with a trapezoidal hub, a new instrument cluster and a center console now turned towards the driver, more comfortable front seats with improved lateral support (optionally with an electric drive for 8 adjustments for the driver's seat and 4 for the passenger). Interior trim - expensive woolen fabric, velor or two types of genuine leather, including nappa.
The new appearance of the Audi A4 is fully consistent with the technical solutions used in it. Choose any of the engines: powerful and progressive gasoline units, as well as efficient, high-torque diesel engines are at your service.
The range of engines includes five gasoline engines: atmospheric fours 1.6 l 8V (102 hp) and 2.0 l 16V (130 hp), turbo engine - 1.8 l 20V (163 hp) . Plus two new gasoline engines: a 3.2-liter V6 FSI with direct fuel injection, which produces 255 horsepower, as well as a two-liter turbo engine with direct fuel injection already known from the Audi A3 and VW Golf V models, with a capacity of 200 horsepower. From zero to one hundred kilometers per hour, both modifications accelerate in 7.3 seconds, and their maximum speed is 250 and 241 kilometers per hour, respectively.
For the Russian market, for now, instead of engines with FSI, a powerful “six” 3.0 liter is offered, developing 218 hp. In addition, three TDI R4 turbodiesels of 2.0 liters (140 hp) and two V6s of 2.5 liters (163 hp) and 3.0 liters (204 hp quattro) are offered. In Europe, the base is the 1.9-liter TDI (116 hp). Audi A4 with a two-liter turbodiesel will be able to accelerate from zero to one hundred kilometers per hour in 9.7 seconds, and with a three-liter - in 7.2 seconds.
Gearboxes are 5- or 6-speed manual or multitronic CVT (front-wheel drive), while the quattro has a 6-speed tiptronic “automatic”. The legendary quattro permanent all-wheel drive provides maximum traction, and the ESP control system of the second generation even in difficult road conditions guarantees a unique level of safety. A4 safety is provided by modernized active (ABS + EBD, Brake Assist) and passive (8 airbags, including adaptive frontal) safety systems.
The luggage compartment volume of the A4 sedans is from 460 to 720 liters, and the A4 Avant station wagons are from 442 to 1184 liters.
The list of additional equipment for the A4 is traditionally wide - these are xenon headlights, active front head restraints that automatically take a C-shape when landing, separate 4-zone climate control, 4 hi-fi class audio systems to choose from (power up to 210 W), trim natural wood and aluminium, 9 wheel designs, navigation system with TV tuner, several steering wheel designs and much more.
In addition to the S-line sports tuning package, a new DTM Edition sports package has been offered since 2005.
The premiere of the next generation Audi A4 Cabriolet 2006 model year took place in Frankfurt. The main design change from the previous version is immediately noticeable: it is the monolithic trapezoidal grille, which first appeared on the Nuvolari concept. Dimensions: length - 4573 mm, height - 1391 mm, wheelbase - 2650 mm.
At the rear, the taillights and bumper have also been redesigned, which houses a diffuser that adds a touch of sportiness. The modern interior is quite consistent with the progressive style of the car's exterior. As standard, the interior of the car is decorated with aluminum inserts, you can also order walnut, gray or beige birch. The interior can be upholstered in fabric, fabric with leather, leather or leather with Alcantara in various colours.
Automatic up can be lowered and raised at speeds up to 30 km / h. Thanks to good thermal insulation and a glass rear window, the A4 Cabriolet can be used without restrictions in winter. As an option, a top with improved acoustic insulation is offered, which allows you to achieve a level of sound comfort comparable to the A4 sedan.
In 2007, a new generation of the A4 sedan enters the market. The continuity of generations, fully inherent in all models from Audi, is evident. The car retained all the recognizable features of its predecessor, but at the same time improved in all respects. The salon has become more spacious, the appearance is more expressive, and the equipment is richer. In a word, the car has become more solid and luxurious. It is noteworthy that the A4 family sedan has been Audi's best-selling model for many years.
The car has many changes. The appearance has become much faster. The car received headlights in the style of the A5 coupe, a bumper with aggressive air intakes, stampings that cut through the sidewalls of the body. The Audi A4 sedan has become 11 cm longer and 6 cm wider. The wheelbase has increased by 158, which has a beneficial effect on the interior space and trunk volume. In a sedan, the volume of useful space in the luggage compartment is 480 liters, in a station wagon - 490 liters in the normal state of the seats and 1430 liters if the rear seats are folded down. In addition to its huge size, the trunk of the A4 Avant has a mounting grid, a 12-volt socket and a double-sided cover, which is covered on one side with soft pile, and on the other with plastic. Plastic is indispensable when transporting contaminated cargo, and a soft fleecy coating will protect the trunk from scratches if the cargo has sharp corners. For transportation of long loads there is a hatch in the backs of the rear row seats.
Audi A4 2007 model year received five types of engines. Two of them are gasoline: one is turbocharged, with a volume of 1.8 liters and a capacity of 160 hp. with., the second - a 3.2-liter V6, developing 265 hp. Thanks to cutting-edge engine development, Audi vehicles are powerful and efficient. All types of gasoline engines are equipped with FSI technology, which allows you to increase the torque and power of gasoline engines, as well as reduce fuel consumption (up to 15%) and reduce exhaust gas toxicity. Unlike manifold injection technology, FSI engines inject fuel directly into the combustion chamber. This reduces internal heat loss, as well as increasing power and reducing fuel consumption.
The most modest diesel modification offers a 2.0 TDI engine with 143 hp. Also, the car can be equipped with 2.7 TDI turbodiesels with a capacity of 190 hp. and 3.0 TDI with 240 hp. TDI engines use modern common rain technology. The latest generation common rail system has a high pressure fuel pump and one distribution line per bank of cylinders. It has a maximum injection pressure of 1,600 bar, 250 bar more than the previous generation common rail system. During injection, an electrical voltage is applied to the ceramic element of the piezo injector, which changes its crystal structure.
The Audi A4 is available with both front-wheel drive and quattro all-wheel drive. The transmission lineup consists of a six-speed manual gearbox, a Multitronic continuously variable variator, and a six-speed automatic transmission. The A4 quattro all-wheel drive transmission can be equipped independently of the engine. The all-wheel drive design has not fundamentally changed, but has undergone a reconfiguration: it has become “a little” rear-wheel drive. When driving on a straight dry road, 60% of the torque is transferred to the rear axle.
Thanks to the use of modern steel grades, the car body has become 10% lighter, while, according to the creators, the body has become more durable, the body must withstand collisions with an obstacle at speeds up to 15 km / h without any consequences at all.
The developers also took care of the safety of passengers and the driver. For these purposes, there are six airbags, front and rear curtain airbags, standard parking sensors, ABS and the ESP electronic stabilization system. In 2007, the Audi A4 received the highest Euro NCAP 5 star rating as one of the safest vehicles in its class.
The basic equipment of the car includes an on-board computer, central locking, electrically adjustable mirrors, power windows, heated seats, a rain sensor. Optional A4 Avant available blind spot monitoring system, adaptive cruise control, sunroof, panoramic roof, hill climb assist, Bang & Olufsen audio system with 500 watt amplifier, 10 active channels and 14 speakers and much more.
In March 2011, the five millionth Audi A4 rolled off the assembly line at the Audi plant in Ingolstadt, an Avant 3.0 TDI quattro in Misano Red.
After four years of production, the third generation was restyled. The car received upgraded engines and chassis, as well as a slightly modified exterior. The car "has grown" by several millimeters in length and height. The hood has become more curved. Designers have changed the shape of the radiator grille, slightly “cutting off” its upper corners. The transverse ribs and rings of the Audi emblem are now more prominent. The grille is painted in gray or glossy black (on six-cylinder models and models with the S line package). The design of the headlights has been updated: their lower edges have acquired a slight wave-like bend; changes also affected the internal structure of the optics. Xenon plus headlights are available as an option. LED daytime running lights are made in the form of a single narrow strip located next to the xenon headlight lenses. Adaptive headlights as well as dynamic and static cornering lights are available on request. The outlines of the rear lights echo the shape of the front optics. When ordered, Xenon plus headlights are continuous LED strips.
The interior was refreshed with additional chrome inserts that appeared on the buttons and steering wheel. The steering wheel itself has been given a sportier look with a cut lower segment, and the navigation system is now controlled by four buttons instead of eight. The interior of vehicles with the S line sports package is finished in black with updated materials. The package also includes 18-inch or optional 19-inch alloy wheels. Otherwise, everything is the same: easy-to-read instruments, a Russified on-board computer and a convenient joystick of the MMI system remained in their place. The trunk has retained its previous volumes - 480 liters (962 liters with the rear seats folded) for the sedan and 490 for the Avant station wagon.
The range of engines includes six diesel (TDI) and four petrol (TFSI) engines in 23. All engines are supercharged with direct fuel injection; a start-stop system and a recovery system are standard on all variants. As a result, average fuel consumption has decreased by 11%. The engines can be combined with a manual transmission, S-tronic dual-clutch robot and multitronic stepless variator, front-wheel drive or all-wheel drive. In total, 23 combinations of engines and transmissions are available for the Audi A4, 16 options are available in Russia.
A new 1.8-liter turbocharged petrol engine has become available for the Audi A4, which can be ordered in two versions - 120 and 170 hp. Standing apart from everyone is the top-end 3.0-liter TFSI gasoline engine, which produces 272 hp. in the version for the Audi A4 and 333 hp. in the version for the sporty S4. As for diesels, the following options are available: a 2.0-liter TDI with a capacity of 136, 163 and 177 hp, as well as a 3.0-liter engine that produces 204 or 245 hp. depending on version.
For the Audi A4 family, quattro® all-wheel drive uses a self-locking center differential. In normal driving mode, it distributes the torque mainly to the rear wheels in a ratio of 40% to 60%. If necessary, redistribution occurs in the shortest possible time. The Torque Sharing function assists the center differential by applying the brakes and giving the car better handling.
Following the “older” models, the A4 was equipped with modern security systems: now the electronics monitor the markings, road signs, the car automatically brakes in front of an obstacle at speeds up to 30 km / h, monitors the driver’s reactions and condition depending on driving style. In addition, there was a system for tracking dead zones.
The presentation of the Audi A4 in the new B9 body took place on June 29, 2015. The world premiere will take place at the Frankfurt Motor Show in September. This is the fifth generation of this model.
The appearance of the Audi A4 2016 has noticeably changed, it has become more aggressive. The author of the updated image is the same designer Walter De Silva. The changes affected several elements at once. Already in the base, the car is equipped with xenon headlights, in which LED daytime running lights are integrated. The taillights received a new geometry and a larger surface area. Dimensions and turn signals are clearly visible in the side projection and rear at a great distance. The fog lights, although they remained at the same level, made some room for the possibility of placing sensors for controlling road markings and thermal imaging equipment.
The car also received a wider Singleframe grille, restyled bumpers (reminiscent of the sporty R model), reshaped rear-view mirrors and more use of chrome trim.
The sloping roof, the sharp angle of the windshield, combined with the stampings located on the side parts of the body, provide a remarkable passage of the oncoming air flow. The drag coefficient has been reduced to 0.23 for the sedan and 0.26 for the station wagon, which in turn will reduce fuel consumption.
In terms of its dimensions, the Audi A4 2016 turned out to be slightly larger than the previous generation car. The length of the sedan is 4726 mm (+ 25), the wheelbase is 2820 (+ 12), the width is 1842 (+ 16), and the height remains unchanged (1427). The Audi A4 B9 (2015-2016) was based on the second generation MLB platform, due to which it was possible to reduce the weight (depending on the modification) by 120 kg compared to its predecessor.
The interior has become an order of magnitude more spacious, for the most part due to an increase in the size of the wheelbase. There was an additional 23 mm for the legs behind those sitting. The driver and passengers can enjoy completely redesigned anatomically shaped seats. In the interior of the Audi A4 2016, a completely different front panel with a free-standing multimedia system screen, a different climate control unit, an even row of air ducts like on the Q7 II and a similar compact gearshift lever, swapped with the MMI control washer. The steering wheel has a minimum of buttons. Minimalism, however, is not at the expense of informativeness. But at the same time, everything is at hand. Any switch can be reached.
The multimedia system of the top versions is equipped with an 8.3-inch tablet with support for voice control, a Wi-Fi hotspot, LTE, Android Auto and Apple CarPlay. Rear seat passengers can also order two 10.1-inch tablets and a Bang & Olufsen audio system.
The trunk of the A4 Avant now holds up to 505 liters of luggage with the rear seats, providing an increase of 15 liters over the old model. When folding the rear seat (40:20:40), the volume increases to 1510 liters.
Front and rear, the car received new five-link suspension. For a surcharge, adjustable shock absorbers are offered with two modes of operation: standard and sports. In the first version, the ground clearance is 10 mm lower than on a car in the version with conventional shock absorbers, and in the sports version it is 23 mm lower.
At the time the model entered the European market, seven power units are available for cars - three petrol and four diesel, as well as a modification of the g-tron, which runs on synthetic methane.
Gasoline engines for the new Audi A4 are represented by a 1.4-liter “turbo four” with a capacity of 150 hp, as well as two two-liter engines with a return of 190 and 252 hp. The latter has Quattro all-wheel drive and accelerates to hundreds in 5.8 seconds. Among the diesels are two two-liter four-cylinder TDI with a capacity of 150 (320 Nm) and 190 (400 Nm) hp, as well as two three-liter "six", developing 218 (400 Nm) and 272 (600 Nm) "horses". With the top sedan gaining a hundred in 5.3 seconds.
TFSI and 4-cylinder TDI engines work as standard with a newly developed 6-speed manual transmission that is 16 kg lighter than the previous one. All engines (except the 3.0 TDI 272 hp) are optionally available with the new 7-speed dual-clutch S Tronic as a replacement for the old Multitronic continuously variable transmission. In turn, the 3.0 TDI (272 hp) is offered with an 8-speed Tiptronic gearbox, which has also gone through a number of changes.
It will also offer the A4 Avant g-tron with a 2.0 TFSI (170 hp) and 270 Nm engine that can run on compressed natural gas (CNG). Cylinders installed under the car can hold 19 kg of gas at 200 bar and according to Audi, with a consumption of less than 4 kg/100 km, the gas range will reach 500 km. When the gas is exhausted, a full tank of gasoline will allow you to drive another 450 km.
It is expected that later the range of engines will be expanded, including through hybrid modifications with the ability to recharge batteries from a household network.
Audi A4 Welcome Baby 😉 280 Nm › Logbook › Little about the A4 and its sores…
I found it on the Internet ... I scooped something for myself ... I post it for everyone ... the note is not mine 😉
The second generation Audi A4 debuted in 2000, and the serial production of the model began in 2001. "Four" shared the platform with the Volkswagen B5. In total, more than a million copies of the Audi A4 B6 were produced in the world. Without even looking at
A4 was offered with a huge number of engines with a working spectrum from 1.6 liters (100 hp) to 3 liters. (220 hp) on the "charged" S-version. Three engines are most widely used: petrol 2.0 l ALT (130 hp), turbocharged petrol 1.8 l (150 hp - avj, 163 hp - bfb, 170 hp - amb (USA) and 190 hp - bex) and diesel 1.9 TDI (100 and 130 hp).
The 2 liter ALT is famous for its immense oil appetite after 100,000 km. Only one thing calms down, the increased oil consumption, as a rule, no longer grows and averages 2-3 liters per 10 thousand km.
Diesel 1.9 TDI reliable unit. With a run of more than 200 thousand km, you will most likely have to pay attention to the condition of the fuel injectors.
Other motors are found occasionally, and severe problems do not appear with them.
Problems with the correct operation of the motor often appear due to the failure of the ignition coils, which "die" in most wrong moment. brand new coil worth about 1200 - 1700 rubles. When going to buy an expensive car, future owners want to know which engine is the most reliable Audi A6 (C6). Difficulties with starting, regardless of the presence of errors, in 90% of cases are associated with a failure of the cooling water temperature sensor.
Hydraulic motor mounts (pillows) with a run of more than 180 - 200 thousand km often require replacement, which will be indicated by the vibration that appears. At mileage over 200 thousand km, most likely you will have to change the crankshaft position sensor (1800 - 2500 rubles) and the mass air flow sensor (1500 - 3500 rubles). By the same time, the thermostat begins to give up, the replacement of which is not an easy job. new unique worth about 3-4 thousand rubles, non-original - 2-3 thousand rubles.
Supercharged 1.8T requires more attention for itself. Interruptions in operation may occur due to loss of density and air leakage in the pipe supplying air from the filter to the turbocharger compressor. Audi slogan: Audi A3 with 1.6 8v is the cheapest in the engine uses aluminum. Often the pipe is wiped with a clamp at the turbine itself, with all this a whistle occurs, and engine does not hold idle. The turbine takes care of more than 200 - 250 thousand km, and with careful operation it lives up to 300 thousand km. A brand new turbine will cost 20 - 25 thousand rubles, its repair will require about 10 - 15 thousand rubles.
The restored turbine is capable of running another 50-60 thousand km. The plastic tee of the cooling water behind the engine, under the influence of temperature and time, shrinks and begins to “poison” the antifreeze. A new one costs about 600 rubles, but to change it you have to "work hard". With a run of more than 160 - 200 thousand km, the electric canister valve No. 80 often fails. The unique one will pull on 4.5 - 5 thousand rubles, the analogue - 1 - 2 thousand rubles.
"Diesel" (crackling) after starting a cold engine for the first 1-3 seconds is caused by a faulty phase regulator, combined with a chain tensioner, and stretching of the chain itself. The modern engine of the Audi A6, in fact, the same engines are on the Audi A4, the same 2.8. The problem is typical for engines of 2.0 liters and 1.8 T and appears with a run of more than 200 - 240 thousand km. In addition, at 1.8T, if it is not time to change the phase regulator, there is wear on the teeth on the exhaust camshaft star that come as an assembly. The new camshaft will require about 13-15 thousand rubles.
The Tiptronic automatic gearbox is generally reliable, but with a run of more than 200-220 thousand km, shifts and slippage may appear. The reason is the wear of friction clutches, repairs will require about 40-60 thousand rubles.
Multitronic was installed only on front-wheel drive versions of the Audi A4 B6. More problematic boxes until 2004 release. The variator requires regular oil changes, otherwise the wear of the chain and cones is accelerated, which leads to “clogging” of the wear products of the filters and valves of the box pump. Which in turn causes jolts, jerks and jerks more often when starting and stopping the car. Repair in this case will require about 70 - 90 thousand rubles.
Vibration at the moment of vigorous acceleration is a frequent occurrence with a run of more than 160 - 200 thousand km. The reason is the wear of the inner CV joint (tripod). A unique one costs about 10 thousand rubles, a non-original one costs 4-4.5 thousand rubles.

Audi A4 is a representative of the luxury class of vehicles. For the entire time of production, a sufficient number of gasoline and diesel power units were installed on the machines.
Specifications of motors
The Audi A4 engines are powerful advanced powertrains renowned for their reliability. Of course, maintaining the engine to the owner is not cheap, but it justifies its money.
General view of AUDI A4
The range of motors is very large. There are engines with a volume from 1.6 liters to 3.2. Power can reach up to 400 horsepower in RS versions. As for diesel engines, they are quite familiar, since they are representatives of the VAG line.
Consider the main technical characteristics of the Audi A4 engines, which are considered the most common:
EA827 1.6 liter engine
Modifications and use of the EA827 engine

Service of power units
Maintenance of Audi A4 power units is carried out in the same way for all power units. The service interval is 15,000 km. You can service the engines, both in a car service, and with your own hands.
The maintenance card looks like this:
TO-1: Oil change, oil filter replacement. Carried out after the first 1000-1500 km of run. This stage is also called break-in, since the elements of the motor are lapped.
TO-2: The second maintenance is carried out after 10,000 km of run. So, the engine oil and filter are changed again, as well as the air filter element. At this stage, the pressure on the engine is also measured and the valves are adjusted.
TO-3: At this stage, which is performed after 20,000 km, a standard oil change procedure, fuel filter replacement, and diagnostics of all engine systems are carried out.
TO-4: The fourth maintenance is perhaps the easiest. After 30,000 km, only the oil and the oil filter element change.
TO-5: Fifth TO for the engine, like a second wind. A lot of things are changing this time. So, let's consider which elements will be replaced in the fifth maintenance:
- Change of oil.
- Oil filter replacement.
- Air filter replacement.
- Replacing the fuel filter element.
- The timing belt and roller or chain are changing.
- If necessary, alternator belt.
- Water pump.
- Valve cover gasket.
- Other items that need to be replaced.
- Valve adjustment, in which the gas distribution mechanism is regulated.
Subsequent maintenance is carried out according to the map of 2-5 maintenance for the corresponding mileage.
Conclusion
Audi A4 engines are one of the standards of reliability. At the same time, the design of most motors cannot be called simple. It is realistic to service the power unit with your own hands, but as for troubleshooting, you will need a trip to a car service.
The Audi A4 is a middle-class car manufactured by the German automaker AUDI AG. The Audi A4, and until 1995 the Audi 80, is the successor to the F103. In 2011, the 5 millionth copy of A4 rolled off the assembly line of the plant. Today, sales are so high that the Audi A4 ranks fourth in terms of the number of cars produced in Germany. The four is made with 4 body types - a two- and four-door sedan, a convertible and a 5-door station wagon.
The EA827 engine with a volume of 1.6 liters was developed back in 1985. It was a block with a short-stroke crankshaft of 77.4mm and cylinder diameters of 81mm. Engine with one camshaft and eight valves in the cylinder head (SOHC 8V). Versions of engines with injection technology on the intake shaft were equipped with variable valve timing. Adjustment of valve clearances on this engine is not needed, because. in the design of the motor there are hydraulic lifters.
The 1.4 TSI EA211 engines are equipped with a turbocharging system paired with an intercooler, which is installed in the intake manifold. Depending on the modification of the engine, various types of turbines are installed. The main advantage of the new series over the old one is the lighter weight of the internal combustion engine and more economical fuel consumption.
Before us is a modified version of the well-known naturally aspirated 1.8-liter VW four-cylinder engine, the main innovation of which was the use of turbocharging. The cylinder head in the engine uses a 20-valve, 5 valves per cylinder, with a variable valve timing system on the intake shaft. There are hydraulic lifters, so you don't need to adjust the valves on the 1.8T. The timing drive uses a belt, which is desirable to change every ~ 60,000 km, if the belt breaks, the motor will bend the valves.
The two-liter engine of the EA113 TFSI series was released in 2004 and was developed on the basis of an atmospheric engine with direct fuel injection VW 2.0 FSI. The main difference between the two engines is not difficult to guess from the first letter added - the new engine is equipped with a turbocharger. This is not the only difference, the power unit must be properly prepared for high power, instead of an aluminum cylinder block, the TFSI uses a cast-iron one with a modified balancing mechanism with two balancing shafts, another crankshaft with thick thrust lugs is used, pistons on reinforced connecting rods changed for a reduced compression ratio.
The 6-speed automatic transmission ZF 6HP19 /A (09L according to VAG) has been used since 2000 for rear- and all-wheel drive BMWs, front- and all-wheel drive Audis (like 6HP19A), Hyundai. Designed for engines up to 3.5 liters. In 2006, the electrics of the box were seriously updated in the next modification of this family - 6HP21. After that, the automatic transmission has a new 2nd generation Mechatronic with improved gear shifting, the valve plate, solenoids have been changed, the 7th hydraulic accumulator has appeared, some friction clutches and almost all steel disks have been replaced.
Automatic transmission ZF 6HP26, which has 6 speed modes, was developed together with BMW specialists. Starting from 2001, it began to be introduced into all prestigious cars equipped with rear-wheel drive and with engines up to 6 liters. The modified ZF 6HP26A was equipped with front-wheel drive Volkswagen and Audi. The torque indicator can reach 600 Nm. Then new automatic transmission modifications appeared - 6HP19 -21 for engines with lower torque (up to 420 Nm), ZF 6HP32 for internal combustion engines with torque up to 750 Nm).
The ZF 5HP19 5-speed automatic transmission was developed in 1995 for front- and all-wheel drive Audis and was designed on the basis of the 4-speed 4HP18 and 5-speed 5HP18 (with which most of the components are identical). The difference between 5HP19 is that it is designed for a slightly higher torque than 5HP18 and was aggregated with engines up to 4 liters.

Audi cars are one of the most desirable representatives of the secondary market. There are several reasons for this interest: the high durability of many models, pleasant finishes, good equipment and excellent technical data. But when choosing a used "car with rings", you should be careful.
First, low prices are often a harbinger of twisted mileage or hidden defects. Second, parts and repairs are often expensive. Even if nothing breaks, maintenance costs will be high. At the same time, with an increase in the Audi class, the cost of ownership increases like an avalanche.
If the Audi A3 is not yet so expensive to maintain, then the Audi A6 may be unbearable. It's all about the more complex suspension, electronics and densely filled engine compartment.
Both gasoline and diesel engines can generate unexpectedly high costs. Among gasoline units, a breakthrough occurred in 2007. Then 1.4, 1.8 and 2.0 TFSI got under the hood of Audi. At the same time, numerous troubles rained down: the timing drive failed, oil zhor appeared, pistons collapsed. The V6 went bad a little earlier, when the fast and durable 2.4 was replaced by the 2.4 FSI.
No less complicated story in the diesel branch. An example of this is the successful 1.9 TDI and the failed 2.5 V6 TDI (the latest versions of which, for example, BAU, have already been practically freed from the drawback). Then came the unsuccessful 2.0 TDI PD with pump injectors and the decent 3.0 TDI V6. The 2.0 TDI PD was later replaced by the improved 2.0 TDI CR with common rail injection.
Gasoline engines
1.6 8V - low maintenance
From a 1.6-liter gasoline aspirated, you should not expect good dynamics and efficiency. However, the Audi A3 with 1.6 8V is the cheapest Audi to maintain. Those who like dynamic driving should stay away from cars with such an engine.
This motor can be found under the hood of the Audi A3 (1st and 2nd generation) and A4 (B5 and B6). It was also widely used in other VW Group vehicles. Moderately decent rides only the first A3, which weighs a little over a ton. A4 B6 for 1.6 is too heavy. The disadvantages include fuel consumption. 9 liters per 100 km seem disproportionately large for mediocre dynamics.
However, in the era of complex motors, this is the only unit that guarantees low operating costs. Among the typical malfunctions, one can only note failing ignition coils and throttle contamination. Nothing expensive. Timing belt replacement? Installation of gas equipment? It doesn’t get cheaper, especially when compared with engines with direct injection and a timing chain drive.
The engine uses an aluminum body and head. The crankshaft is supported by five bearings, and multi-point (distributed) injection is responsible for the fuel supply. The camshaft is located in the head of the block.
Advantages:
Simple construction;
Cheap repair;
It tolerates the introduction of HBO;
The low cost of the car.
Flaws:
Poor dynamics (overtaking is difficult, especially in the case of the A4);
Relatively high fuel consumption.
1.8 Turbo - powerful and reliable
The 1.8-liter turbocharged engine is still worthy of attention. It is durable and fairly cheap to repair. The possibility of tuning is also appreciated.
1.8 T provides decent performance and reasonable fuel consumption. This is one of the first turbo engines to be widely used. It can be found not only in Audi, but also in Volkswagen, Skoda and Seat. The engine was used even in industry.
The unit has a cast iron block, a forged steel crankshaft and an aluminum block head with 20 valves (3 intake and 2 exhaust per cylinder). A toothed belt is used to drive one camshaft, while the second shaft is connected to the first by a short chain. Turbine KKK without movable blades (invariable geometry), and fuel injection is distributed. The block in the "dry state" weighs about 150 kg.
It soon became clear that the 1.8 Turbo had a lot of potential. Serially, 240 hp was removed from it, and in the process of tuning it easily withstands boosting up to 300 hp. Of course, in the case of a tuned unit, vigilance should be increased, since it may already be hackneyed.
And yet, more often the turbo engine was not used for sports trips. Under normal conditions, a car with such an engine consumes from 9 to 14 liters per 100 km.
With age, a number of shortcomings were discovered (timing belt and thermostat), but their elimination does not require large expenditures.
Advantages:
Good compromise between performance and fuel consumption;
Availability and availability of spare parts;
Wide selection on the market.
Flaws:
Several unpleasant typical defects in older cars with high mileage (oil consumption and timing problems).
Application examples:
Audi A3 I (8L);
Audi TT I (8N);
Audi A4 B5, B6 and B7.
2.4 V6 - only until 2005
Despite the emergence of increasingly powerful inline turbo-fours, Audi fans still prefer naturally aspirated petrol V6s, especially in early versions. Of course, you should not count on low fuel consumption - at least 10 liters per 100 km. In the city you have to reckon with even 20 liters. But, the trip will seem pleasant.
Two generations of the 2.4-liter engine should be clearly distinguished. They have the same volume and dimensions, but in 2004 there was a modernization. Before the upgrade, the block was cast iron, and the head had 30 valves (5 per cylinder). After that, the block became aluminum, the number of valves decreased to 24, direct injection and a timing chain appeared.
The latest innovations have failed. Due to the direct injection system (FSI), carbon deposits accumulated on the valves after several tens of thousands of kilometers. There were problems with the timing chain tensioner and a small mesh filter in the lubrication system. Complete disregard for noise often resulted in chain jumps and serious damage. In 2008, Audi eliminated the vulnerability of the timing drive, but the engine could not withstand the pressure of 4-cylinder turbo engines.
Advantages:
Good elasticity;
High reliability (only before upgrade);
Versions with distributed injection easily tolerate the installation of LPG.
Flaws:
The limited meaning of installing HBO in an updated version of FSI;
Expensive timing failures (FSI);
Fairly high fuel consumption.
Application examples:
Audi A4 II (B6);
Audi A6 C5 and C6.
Diesel engines
1.9 TDI - durable and economical.
This is the most recognizable diesel of recent years. Even an older Audi with a 1.9 TDI is worth looking at - solid construction and inexpensive repairs.
1.9 TDI - the engine is a legend. Produced since 1991 and modernized many times. It has found application in many other VW Group vehicles.
The most reliable and cheapest in operation and repair is the 90-horsepower version with a distribution-type injection pump. The engine has a simple design, a constant geometry turbine and a single-mass flywheel.
Yes, minor problems sometimes happen. For example, with an exhaust gas recirculation valve, an air mass meter and a fuel pump. But for the most part, malfunctions are not caused by design flaws or poor quality, but by a decent age and high mileage.
The younger and more powerful versions of the 1.9 TDI have more solutions that can create problems. We are talking about a turbine with variable geometry, a dual-mass flywheel, pump injectors and a DPF. However, even these versions against the background of diesel engines appear in a more favorable light.
The exception is the 2006-2008 BXE version, which, for example, fell under the hood of the second generation Audi A3. There are many cases of turning the liners after 120-150 thousand km.
Advantages:
Simple construction;
Good endurance;
Low fuel consumption.
Flaws:
Many hackneyed copies (the engine was installed until 2009, and since 2004 it has been gradually replaced by a 2-liter turbodiesel);
Low work culture: noise and vibration, especially after starting a cold engine.
Application examples:
Audi A3 I (8L) and II (8P);
Audi A4 B6 and B7;
Audi A6 C4 and C5.
2.0 TDI CR - all is well at last
A 2-liter diesel engine is the main unit for most Audi models. Since 2007, he began to use the common rail injection system.
The design flaws of the 2.0 TDI with unit injectors prompted Volkswagen engineers to thoroughly modernize it. Changing the way you eat is the most important innovation. The pistons were also updated, problems with the oil pump drive were eliminated, a new block head and camshafts were installed. As a result, the durability of the engine was significantly improved, but there were also disadvantages.
When buying an Audi with a 2.0 TDI engine, you should check the history of the car. Often, these were cheap and economical versions purchased for commercial or corporate garages. They have huge mileage and have not always been well maintained.
Typical malfunctions affect the dual-mass flywheel and turbocharger. Piezoelectric injectors fail here no more often than competitors. Luckily, they are repairable. As part of the service campaign, the manufacturer changed high-pressure lines.
Advantages:
Good performance with acceptable fuel consumption;
Good durability (especially compared to 2.0 TDI PD);
Great variety of versions.
Flaws:
Expensive maintenance (complex design and expensive spare parts);
Significant mileage of many copies, despite the relatively young age.
Application examples:
Audi A4 III (B8);
Audi A6 III (C6).
3.0 TDI - for demanding
High performance and dynamics are not the only advantages of the 3.0 TDI. Therefore, many choose it with pleasure, even despite the rather high maintenance costs.
The 3.0-litre turbodiesel was intended to correct the bad reputation of Audi's diesel V6s, which had been tarnished by the 2.5 TDI V6. The 3.0 TDI earned respect not only for its performance, but also for its durability. The block, cylinder head and crank mechanism turned out to be very strong. For each cylinder there are 4 valves and one piezoelectric injector.
The problems concern mainly the equipment. Most often they encounter a timing drive, the cost of replacing which is very expensive. Until 2011, 4 chains were used, and after - two. The drive chain is located on the gearbox side. To replace it, you have to remove the engine.
Not spared from the shortcomings of the damper in the intake manifold (repair kits are available) and DPF. The engine is constantly being improved, and in later versions, malfunctions are much less common.
Advantages:
High culture of work;
Good performance;
Low fuel consumption;
Good service life of many engine parts.
Flaws:
Expensive to troubleshoot timing, intake manifold and DPF;
Many copies on the market have high mileage and questionable technical condition.
Application examples:
Audi A5 I (8T/8F);
Audi Q7 I (4L);
Audi A8 II (D3).
Risky choice!
There are engines in the Audi range that are great in theory but painfully disappointing in practice. In particular, the first generation 1.4 TFSI with a problematic timing chain drive should be mentioned. Currently, a more reliable version with a timing belt drive is used.
The 1.8 and 2.0 TFSI engines with the code designation "EA888" tempt with high performance. However, they suffer from high engine oil consumption. There are problems with the turbine, camshafts and electronics.
There are black sheep among diesel units. For example, a 1.4 TDI with pump injectors was installed in the Audi A2. The problem is the appearance of crankshaft play, the elimination of which is not economically feasible. The 2.0 TDI PD is known for its cracking head and poor equipment durability. 2.5 TDI V6 is tormented by numerous blunders with the timing, as well as with the lubrication and power system.
Conclusion
Once upon a time, buying an Audi was easier - the engines guaranteed quiet operation. Currently, you need to pay attention to the version. Along with really successful engines, those for which the designers should be ashamed were also used. At the same time, even a fairly reliable modern engine will be expensive to maintain and maintain.
