Progress and developments in automotive industry walk at a fast pace. Aggregates are being developed in the same way. Rating of the best modern engines, characteristics and vehicles on which they are installed.
The content of the article:
Talking about which engine is the best, gasoline or diesel, as well as about the manufacturer - Japanese, German or American - opinions will definitely be divided. Some drivers prefer a powerful and reliable unit, others - an engine designed for speed, and still others - so that it is durable and does not fail. The main difference between the engines is the class of the car on which it will be installed. As a result, the volume of the unit, characteristics and power will change.
Experienced car owners will say that the main thing in a car is that the engine works normally. Usually, the first signs of engine wear appear after 100-150 thousand kilometers. It’s good if the car owner is alone and looks after the engine, but if there were several owners from the beginning of the purchase and they didn’t look at the car engine, then repairs will be needed much earlier, and the cost can be much more.
Before buying a car, buyers are often concerned about the same question, which engine is better to choose. Engineers thought out some models of engines to the smallest detail, and despite the inexpensive cost of the car, there will be no problems with the engine. In another case, having bought an expensive premium car, the engine does not leave even 50 thousand km, as the first problems and breakdowns begin to appear.
The best car engines
Nowadays, engineers develop engines so quickly that sometimes they don't think about quality in order to announce a new model of the unit. Suffice it to recall small-capacity turbocharged versions, in which the first breakdowns appear even before 40 thousand. But still, despite the rapid progress, there are also legends in the updated version - these are the so-called "millionaires" who have declared themselves from the best side.
Modern cars among specialists are considered disposable, since the repair of the engine and individual components can cost as much as the entire car from the passenger compartment. The average service life of such cars is from 3 to 5 years, but much will depend on the nature of the operation of the car. There are options, the same car, with the same operating conditions, but different engines, can go a different distance. This is due to the presence different engines, their build quality and engineering.
Rating of the best modern engines
Diesel millionaire OM602 from Mercedes-Benz
Mercedes-Benz diesel engines are quite popular and have gained a good reputation among competitors. Well-known diesel engine Mercedes-Benz back in 1985, but during its existence it has experienced more than one modification, which has made it possible to reach the present day. Not as powerful as competitors, but economical and hardy. The power of the unit is from 90 to 130 hp, depending on the modification, on modern cars it is marked as OM612 and OM647.
The mileage of many such specimens starts from 500 thousand kilometers, although there are also individual rare specimens, the record of which is a couple of million kilometers. This engine can be found on Mercedes-Benz in the back of the W201, W124 and in the transitional W210. Also found on the G-Class SUV, Sprinter and T1 minibuses. Experienced drivers say that if they take care of replacing the necessary parts in time and sort out the fuel system, then the engine is almost unkillable, which adds a lot of stars to its rating.
Bavarian BMW M57
Bavarian BMW manufacturer decided to keep up with Mercedes-Benz and developed an equally worthy M57 diesel engine. The in-line 6-cylinder unit has won the trust of many car owners of this company. In addition to the previously mentioned reliability, the unit is distinguished by power and agility, which is not often found on diesel engines. For the first time, the M57 diesel unit was installed on the BMW 330D E46, at the same time the shorty was immediately transferred from the class of slow cars to the class of sports and charged ones, despite the fact that there is a diesel engine under the hood. The power of the unit, depending on the modification, ranges from 201 to 286 horses. In addition to BMW cars of all possible series, this engine is also found on range cars Rover. Suffice it to recall the ethnographic expedition of Artem Lebedev and his famous “mumusik”. It was under his hood that the M57 from BMW was installed. The declared mileage by the manufacturer is about 350-500 thousand kilometers.
3F-SE petrol engine from Toyota
Despite the huge mileage of diesel engines, most drivers prefer to buy a car with a gasoline engine. The gasoline unit does not freeze in the cold season, and the device of the engine itself is much simpler.
You can argue for a long time which gasoline engine is better and which is worse, because each has its pros and cons. The list of 4-cylinder gasoline units opens with 3F-SE from Toyota. The volume of the unit is 2 liters and is designed for 16 valves, the timing is driven by a belt and a fairly simple distributed fuel injection. The average power, depending on the modification, is 128-140 horses. More advanced versions of the unit are equipped with turbines (3S-GTE). This modified unit can be found both on modern cars Toyota, and older: Toyota Celica, Camry, Toyota Carina, Avensis, RAV4 and others.
A huge plus of this engine is the ability to freely transfer heavy loads, convenient location of nodes for maintenance, easy repair and thoughtfulness individual parts. Subject to good care and without major repairs, such a unit can safely move 500 thousand kilometers with a good margin for later. Also, the engine does not go over in fuel, which does not bring additional worries to the owner.
Japanese unit 4G63 from Mitsubishi
Mitsubishi does not give up its position in the structure of middle-class engines. One of the most famous, surviving to this day 4G63 and its modifications. The engine was first introduced in 1982, despite the prescription, a modified version is still being installed today. Some come with a SOHC three-valve camshaft, another DOHC version with two camshafts has gained more popularity. As an example, a modified 4G63 unit is installed on Mitsubishi Lancer evolution, different models Hyundai and Kia. Also found on Chinese cars brand Brilliance.
Over the years of production, the 4G64 unit has gone through more than one modification, in some versions a turbine has been added, in others the timing adjustment has been changed. Such changes are not always beneficial, but as the owners note, the maintainability of the unit has remained the same, especially in the case of an oil change. Non-turbocharged Mitsubishi 4G63 units are classified as millionaires, although with careful operation, turbocharged options reach a record distance.
D-series from Honda
Closes the top five japanese engine D15 and D16 from Honda. Better known as the D-series. This series includes more than ten modifications of these units, from 1.2 liters to 1.7 liters. and really deserve the status of unkillable units. Engine power from this series reaches 131 hp, but the tachometer needle will show about 7 thousand revolutions.
The platform for the installation of such units was Honda cars Stream, Civic, Accord, HR-V and American Acura Integra. Before a major overhaul, such engines can go about 350-500 thousand kilometers, and due to a well-thought-out design and right hands, you can give the engine a second life even after terrible operating conditions.
European x20se from Opel
Another representative from Europe is the x20se engine of the 20ne family from Opel. The most important advantage of this unit is endurance. Repeatedly there were statements from the owners when the unit outlived the body of the car. A fairly simple design, 8 valves, a belt on the camshaft drive and enough simple system fuel injection. The volume of such a unit is 2 liters, depending on the modification, the engine power ranges from 114 hp. up to 130 horses.
During the production period, the unit was installed on Vectra, Astra, Omega, Frontera and Calibra, as well as on Holden, Oldsmobile and Buick cars. In Brazil, at one time they produced the same Lt3 engine, but with a turbocharger, with a capacity of 165 horses. One of these variants of the C20XE engine was installed on racing Lada and Chevrolet, and as a result, the cars were noted in the rally. The simplest versions of the 20ne family of units can not only cover 500,000 km without overhaul, but with care, they can overcome the bar of 1 million kilometers.
Notable V-8s
The engines of this group, although not very famous for their reliability, do not bring worries with minor or major breakdowns. V8 units that can easily cross the mark of 500 thousand kilometers can be easily listed on the fingers. The Bavarians are back in the cell with their M60 V8, a huge plus: double row chain, the coating of the cylinders is nikasil, as well as an excellent margin of safety of the engine.
Thanks to the nickel-silicon coating of the cylinders (more commonly found as Nikasil), it makes them virtually indestructible. As practice shows, up to a mark of half a million kilometers, the unit should not be disassembled, and replacement of piston rings will not be required. Fuel is considered a minus, it is necessary to carefully monitor the quality of gasoline, since the nickel coating is afraid of sulfur in the fuel. In the USA, because of such a problem, they switched to a softer protection technology - Alusil. Upgraded modern version considered M62. Are established on BMW 5th and 7th series.
Six cylinders in line
There are a lot of millionaires among such engines, simple design and balance - this is what leads to reliability and durability. Two engines 1JZ-GE with a volume of 2.5 liters and 2JZ-GE with a volume of 3 liters from Toyota are considered the best in this class. These units are produced simple and turbocharged.
Most often, such engines are found on right-hand drive Toyota vehicles Mark II, Supra and Crown. Among american cars they are Lexus IS300 and GS300. Due to their simple design, such engines can easily overcome the mark of a million kilometers before a major overhaul is needed.
Bavarian BMW M30
History of the Bavarian BMW engine The M30 has been dragging on since the distant 1968. During the period of the unit's existence, many modifications were made, but despite different situations, the engine still established itself as one of the most reliable. The working volume is from 2.5 liters to 3.4 liters, with a capacity of 150-220 horses. The highlight of the design of the unit is cast iron block(in some modifications it can be made from a special aluminum alloy), a timing chain, 12 valves (the M88 modification comes with 24 valves) and an aluminum cylinder head.
Modification M102V34 is a turbocharged M30 with a capacity of 252 horses. This engine is in different modifications installed on the 5th, 6th and 7th BMW series. There is no data yet, what was the record for this engine in terms of mileage, but the mark of 500 thousand kilometers is an ordinary barrier. As many have noted, this engine often outlasts the car itself as a whole.
Another Bavarian - BMW M50
Last place in the ranking best engines takes Bavarian BMW M50. The working volume is from 2 to 2.5 liters, engine power is from 150 to 192 horses. The advantage of such a unit is the modified VANOS system, contributing better job. In general, it differs little from the previous options, so it overcomes the mark of half a million kilometers without major repairs.
The presented rating of the best engines is not complicated enough. Still ask which car engine is the best. Motorists may say that some units were not included in the list, but the rating was formed on the basis of durability and resource. Hybrid and electric motors are not included due to cost, and the maintenance of such units is special. Individual copies simply cannot be repaired at home, which is why they say that modern cars are mostly disposable.
Video review of the TOP 5 worst engines:
Everyone knows that once, in the distant 80s and 90s, there were "millionaire" motors that served faithfully for hundreds of thousands of kilometers. So, in fact, it is - we compiled them not so long ago. But there are worthy successors of the cause of "millionaires" even today.
For some reason, it is believed that modern cars are disposable. Ride three years, sold and went for a new one. But this is at least an exaggeration and a generalization. Indeed, there is, but this is only part of the market. People own cars for 5-7 or even 10 years and, scary to say, buy them second-hand! So, reliable motors exist. Question: how to find them?
What car and with what engine to buy, so that it not only does not break down during the warranty period, but also does not fall under recall campaigns, does not require expensive consumables and special service equipment. He ran happily ever after, albeit more slowly, consuming a little more fuel than more progressive brothers.
Different classes of cars have their own leaders, and, of course, more complex and expensive cars are not well suited for harsh operating conditions, but they also have their leaders and laggards in terms of the required amount of maintenance and the likelihood of failure.
Renault 1.6 16v K4M
small class
Renault's sixteen-valve K4M engine is just a little more complicated and a little more expensive. Not so easy to carry high loads. But they install it not only on Logan, but also on Duster, Megane, Kangoo, Fluence and other cars.
Middle class
There is already one of the leaders in reliability in the C-class - this is the mentioned K4M from Renault. But cars are somewhat heavier, cars with automatic transmission are more common, which means that the power requirements are slightly higher. 1.6 engines will obviously have a smaller resource than engines with a displacement of 1.8 and 2 liters, which means that it is worth highlighting 1.6 engines in a separate group for those who do not need to drive fast.
Probably the simplest, cheapest resource engine for cars in the C-class can be called the very venerable Z18XER. The design is the most conservative, except that phase shifters and an adjustable thermostat are installed. Timing belt drive, simple injection system and a good margin of safety. The power of 140 forces is enough for comfortable movement of such difficult machines as Opel Astra J and Chevrolet Cruse as well minivan Opel Zafira.

The second place in terms of reliability can be given to a series of engines from Hyundai / Kia / Mitsubushi G4KD / 4B11. These two-liter engines are the heirs of the famous Mitsubishi 4G63, including in terms of reliability. Not without a timing system for adjusting the timing phases, and in its drive there is a completely reliable chain. Simple power system and good build quality, but chain drive The timing is more complicated and more expensive, and the motor itself is noticeably more technologically advanced, so only second place. The power of the motors, however, is noticeably higher, all 150-165 hp. This is more than enough for any C-class car with any load, on the highway and in the city, with automatic transmission and with “mechanics”. Such engines were installed on a huge number of cars, here are the Hyundai i30, Kia Cerato, Ceed, Mitsubishi Lancer and other cars and crossovers of a higher class: Mitsubishi ASX, Outlander, Hyundai Sonata, Elantra, ix35 and Kia Optima.
The Renault-Nissan MR20DE / M4R engine may well claim third place. This two-liter gasoline engine has been produced for quite a long time, since 2005, and in design it also goes back to the “glorious ancestors” of the F-series from the 80s. The key to success lies precisely in the conservatism of the design and a moderate degree of forcing. Compared to the leaders, it has a less reliable cylinder head, sometimes the chain still stretches, but still it allows you to exchange all three hundred thousand kilometers with careful operation, and the price of spare parts does not go off scale.
Junior business class
In the D + segment, two-liter engines from among the C-class reliability leaders are also popular, and here they look good, because the mass of cars does not differ so much. But complex and “prestigious” motors are more popular. high power.
Motor 2AR-FE with a power of 165-180 hp and a working volume of 2.5 liters is installed on one of the bestsellers in the D + segment, on Toyota Camry, and without a doubt is the most common and reliable motor in its class. They are installed on RAV4 crossovers, and on Alphard minivans. The motor is quite simple, but the key to success is in the quality of execution and frequent maintenance Toyota cars.

The second place is deservedly received by the G4KE / 4B12 motors Hyundai/Kia/Mitsubishi. These engines have a working volume of 2.4 liters and a power of 176-180 hp. installed on Kia Optima, Hyundai Sonata, many other passenger models and a galaxy of Mitsubishi Outlander/Peugeot 4008/Citroen C-Crosser crossovers. The design is close to the G4KD / 4B11 motors, and in the same way they are the heirs of reliable Mitsubishi motors. Design without any special frills in the form of direct injection, timing chain drive plus phase shifters. A good margin of power and resource, not too expensive parts- that's the key to success.
But there will be no third place. Turbo engines on European cars noticeably more difficult to operate and potentially more vulnerable. Relatively reliable turbodiesels still require a higher quality of service. And the third place goes to fairly simple units, for example, the already mentioned Z18XER on Opel Insignia or Duratec Ti-VCT on Ford Mondeo, and if you have enough power and you drive calmly, then they will also be the most inexpensive to operate.
Senior business class
Prestigious E-class sedans are not low cost cars, and the engines in this class are complex and powerful. And often they cannot boast of special reliability. But even among them there are leaders and units with high reliability.
Again, Toyota is in the lead, or rather Lexus, but you know what the company is? Motors 3.5 of the 2GR-FE and 2GR-FSE series are installed on Lexus ES and GS models and on luxury Lexus SUVs RX. Despite the high power and low weight, this is a very successful gasoline engine; in the version without direct injection, it is considered one of the most trouble-free in its class.
The second place is deservedly taken by Volvo with its B6304T2 in-line "six" with a volume of 3 liters. The first turbo engine in our rating turns out to be even simpler and cheaper than diesel engines in operation. Largely due to the venerable age of the design with a good margin of safety and relatively low prices for service.
Unfortunately, the naturally aspirated 3.2 is no longer available, it is undoubtedly even more reliable and could claim first place in this category. The secret of success lies in the modular design of the engines. This family has been produced since 1990 to the present day in four, five and six cylinder versions. Continuous improvement of the design and rich experience in the operation of motors has a good effect on the reliability and cost of operation.
For Infiniti, which is in third place, in this class, the Q70 model plays with the legendary “six” of the VQVQ37VHR series with a volume of 3.7 liters and a power of 330 hp. The key to success in this case, too, is the quality of execution, the glorious and long history of the series of motors and prevalence. Such motors were installed on the sports Nissan 370Z, and on the QX50 and QX70 SUVs, and on the smaller Q50 sedan.
In the photo: the engine from the Infiniti Q70
The list of E-class cars will be incomplete if we do not mention an indispensable attribute of European cities - diesel Mercedes E class in the back of the W212 and with the OM651 engine. Yes, this is a turbodiesel, but in its weakest version, with conventional electromagnetic injectors, it is able to deliver a minimum of hassle in operation. Yes, such a machine is fully serviced without dealer service impossible, but, as practice shows, simple configurations, and even with manual transmission surprisingly reliable, no wonder a European taxi for many is a diesel “yeshka”.
executive class
Don't expect a rating here. An F-class car is never cheap to operate, a modern car of this level contains all the achievements of recent years, all the most complex and expensive equipment. Of course, they have their leaders and their outsiders, especially since German executive sedans are produced with very reliable diesel engines, while Korean and Japanese premium brands focus on the reliability of gasoline engines and warranty. But it is difficult to make a choice between them, and it does not make sense, in this class there are other rules of the game.
When buying a car, every driver is interested in what is the most reliable engine. The safety and durability of operation depends on this factor. vehicle. It should be noted that each motor has its own characteristics regarding reliability and resistance to various influences. Let's look at which engines can claim to be truly the best.
The best among diesels
To begin with, let's determine which is the most reliable engine among diesel varieties. Let's just say that recently cars with such units have become more and more popular. They are distinguished by their sporty character, speed, and stability of work. If you drive a lot and often, diesel engines are simply irreplaceable for these purposes. And if the motor is of the old generation, with a simple design, it has a good margin of safety.
Mercedes-Benz OM602
The most reliable for Mercedes-Benz is from the OM602 family. such engines are represented by 5-cylinder versions. They have two valves per cylinder, mechanical injection pump. Drivers note that this motor is the leader in the following characteristics: car mileage and impact resistance environment. With not the highest power (90-130 hp), the units have always been considered the most reliable and economical. These motors were placed on Mercedes cars in the back of W124,W201(MB190), G-class SUVs, T1 vans and Sprinter. If you monitor the fuel equipment and attachments in a timely manner, these diesel engines are capable of "winding" a huge number of kilometers.
BMW M57
Probably the most reliable engines cars modernity is created in Bavaria. In addition to durability, they are characterized by a sporty spirit, which in principle changes the image of a diesel engine. BMW engineers were able to prove to the whole world that such a unit can be fast, and you can put it on any type of car. There are a variety of powertrains in cars, and diesel engines have become popular not so long ago.
Which is the most reliable diesel? Experts focus on the turbocharged 4-cylinder engine BMW N47D twin turbo, which has a volume of 2.0 liters. It was declared the winner in the "Best New Development" category. Note that this motor is put on a huge number of models. And in general, buyers prefer diesel, which can freeze in winter.
bmw
The most reliable in 2016 is the BMW B58, which is put on cars of the 340i F30 models. It's a 6 cylinder power unit, which is gradually being equipped with new models of BMW cars. It should be noted that BMW is systematically introducing both gasoline and diesel engines of the modular family into its vehicles. Their feature is unified components and a single half-liter working volume of one cylinder. At the same time, since 2015, BMW hatchbacks have been equipped with 118i engines with a 1.5-liter turbocharged engine with a power of 136 hp. With. A coupe and convertibles of the second series - diesel engines of 2.0 liters.
The most reliable BMW passenger car engines, according to experts, are not petrol, but TwinPower Turbo diesel units with three or four cylinders. The B47 and B37 engines are supplemented with an injection system and turbochargers that can change geometry. In the same 2015, BMW models were supplemented with a new generation of productive four with a capacity of 23 hp. With. Thus, BMW engines are reliable and high-powered, albeit simple in design.
Note that the average resource BMW engines estimated at 150,000 km, as their parts are not always of outstanding quality. In addition, not all models in the line have factory repair dimensions. Therefore, problems may arise with the replacement of power units.
Audi
Which Audi engines are the most reliable? There is no definite answer here. But both users and experts highlight gasoline engines 1.4 liters with a capacity of 150 liters. s., 190 l. With. and 252 l. With. And the latter is supplemented all-wheel drive Quattro. Among diesel units four-cylinder TDI engines with a power of 150 hp are in demand. With. and 190 l. With. In addition to them, a 6-speed mechanical box gears.
Another engine that can be distinguished as the most reliable Audi engine is the A4 Avant g-tron 2.0 TFSI (170 hp). Its feature is the ability to work on a compressed natural gas. As for the Audi A6 model, here users distinguish a three-liter aspirated. Its reliability is due to the old production technology and cast iron sleeves. True, such a motor has not been produced since 2008.
Volkswagen
It is noteworthy that the Volkswagen brand considers diesel engines to be the most reliable units. In the entire range of engines, the most reliable Volkswagen engine is the 5-cylinder AXD with a displacement of 1.8 liters. According to both drivers and specialists, this motor good with excellent power capabilities with a rather modest fuel consumption. In most cases, the Volkswagen Tiguan is equipped with this unit.
It is not so easy to determine the most reliable engine among gasoline configurations. In this list, it is necessary to note the stable 2-liter AWM engine, showing a power of 140 hp. With. They are equipped with models such as Jetta, Tiguan. Among the advantages of the motor, users note excellent behavior with any driving style and on any road surface.
For a long time it was considered the most reliable. Among its advantages, excellent dynamics during movement, power, and fast acceleration were distinguished. The unit is liked by those who often travel to nature, where the roads do not differ in quality and evenness. The most reliable engines among six-cylinder models are ABU with a volume of 1.8 liters. With a simple design, the unit is good for drivers who are just starting to drive a car. In addition, it is balanced. When the motor is running, there is no vibration of the main mechanisms and components. This engine is able to serve even with a run of more than a million kilometers.
Japanese production
The most reliable engines ever made Japanese brands. We offer an overview of the most popular and best in terms of quality and reliability of motors. Probably the most stable in behavior can be considered Toyota unit 3S-FE. While reliable, it is also unpretentious. It has a volume of 2.0 liters, 4 cylinders and 6 valves. This engine was installed on such models as Camry, Carina, Corona, Avensis, Altezza. According to mechanics, the motors of this series are distinguished by their amazing ability to withstand any load. In addition, it is easy to repair due to a well-thought-out design. The Toyota 1‑AZ series engine, whose resource is about 200,000 km, performed well in operation.
The most reliable car engines can also be distinguished among the line for Mitsubishi. Mitsubishi 4G63 is a power unit that has been constantly changing and improving, due to which it began to be equipped with a timing system for adjusting the timing, complex boost systems. It is noteworthy that the motor is installed not only on Mitsubishi, but also on cars of the brands Huyndai, Kia, Brilliance. A million kilometers of run can be achieved by naturally aspirated engines, although turbocharged variations have great resource work. There are no serious "diseases" in the Mitsubishi 4B11 series motor, which has a resource of 200,000 km. Due to the high quality of the elements, the simplicity of the design, the absence intricate details achieved high level unit reliability.
Honda D-series is a representative of the Japanese family of engines, in the series of which there are more than 10 models of engines with a volume of 1.2-1.7 liters. According to experts, these are perhaps the most indestructible models that can show a combat character with a small working resource. Among the novelties are Honda motor R20 series. It is distinguished by high quality parts, a simple valve adjustment scheme. The most reliable representative of Japanese motors can rightfully be considered Subaru series EJ20. It is still installed on some car models, however, only those that are operated in Japan. The resource of this power unit is 250,000 km, the quality of parts is high. True, original spare parts for the motor are not cheap.
Opel 20ne
Among the reliable ones, one can note a model from the Opel 20ne engine family. Its peculiarity is that it served much longer than cars for which it was used. Simple design consists of 8 valves, belt drive, simple system multipoint injection. This, according to experts, affects the longevity of the motor. C20XE is another motor that belongs to Opel family. It was installed on racing cars and has earned good reviews for its quality, stability and simple design. True, today this power unit is used to equip vehicles infrequently.
Class struggle
All modern motors can be divided into classes in accordance with the classes of vehicles on which they are placed. And this affects their technical and operational properties. So, in a small class of cars, which, by the way, is the most common in our country, they are distinguished by practicality and the absence of any major innovations. For cars in this segment, the K7M engine from Renault is most often installed, which has the highest reliability rates. Her recipe, by the way, is very simple: the engine has a volume of 1.6 liters, 8 valves, but it does not have any complex parts and mechanisms. On the second and third places in the small class, you can put the power units VAZ-21116 and Renault K4M.
In the middle segment, the K4M from Renault can rightfully be considered the leader. True, the machines themselves are different large dimensions and power, are equipped with automatic transmission, which increases the requirements for power and motor. Among the cheap but practical engines in the middle class, the Z18XER can be noted, which is installed on cars l Astra J, Chevrolet Cruse, Opel Zafira.
In terms of reliability, we will put the Hyundai / Kia / Mitsubushi G4KD / 4B11 series of engines in second place in the middle class, which are always leaders in quality and performance characteristics. Their working volume is 2.0 liters, there is a timing system for adjusting the timing, a simple power system, and high build quality. Such motors are put on any cars enough high power and manufacturability: Hyundai i30, Kia Cerato, Mitsubishi ASX, Hyundai Sonata.
Junior business class
In the junior business class, two-liter engines can be distinguished. For example, 2AR-FE with a capacity of 165-180 hp. with., which is equipped with Toyota Camry. This is a reliable and practical power unit. While simple, it is of high quality. In second place in the business class are the G4KE/4B12 Hyundai/Kia/Mitsubishi engines. Cars in this segment differ in size and power. Accordingly, the engine must meet the requirements of operational reliability and manufacturability.
Senior business class
Senior business class prestigious sedans which are expensive to maintain. And the motors themselves differ in complexity and power. Leading the way in this Lexus class: 2GR-FE and 2GR-FSE engines are installed on models of this brand and premium SUVs. The operation of the motor, according to users and experts, does not differ in the presence of problems.
Second in this Volvo class The B6304T2 is a turbo engine that is cheap and easy to operate. In third place is the Infiniti Q70 VQVQ37VHR. It attracts attention with its power, glorious performance, and reliability, which has developed historically. As for luxury cars, you will have to do without a rating, as their operation and maintenance cost a pretty penny. Accordingly, the equipment of such machines is at a height, but it requires serious investments.
conclusions
Thus, a car of almost every brand or class can be equipped with reliable, and therefore trouble-free engines. When choosing your car, be sure to find out everything you can about its engine. After all, the durability of the operation of the entire vehicle depends on its quality and reliability. True, many motors are no longer used to equip modern cars.
Diesel engines for cars are different, and it's not just the volume and number of cylinders, so let's try to briefly review the modern market and find out which of the engines are the most reliable.
To whom did the ratings give leadership?
Associations with the word "diesel" among a resident of Russia are always unambiguous: the smell of diesel fuel from passenger bus, black cinder from a passing truck, vintage jeans and a watch from the brand of the same name. Nevertheless, for most Europeans, the word derived from the name of a German inventor is synonymous with a reliable, inexpensive and powerful “heart” of a car. In our country, its popularity is not so high, apparently due to weather conditions and knowledge that diesel fuel thickens in the cold.
Reliability ratings, and especially for cars, are a thankless task. How many opinions, so many lists, in which the compiler simply expresses his view on a particular subject. That is why we want to draw your attention to the fact that the rating below does not claim to become an indisputable truth, but is just an attempt to systematize the data, knowledge and (partially) personal point of view of the compiler.
In search of an answer to the question of which diesel engine occupies a leading position in the configuration of passenger cars, you can see that some ratings call the most the best products concerns Mercedes and BMW. However, the situation in the world of the automotive industry today is somewhat different, let's try to figure it out.
As the ratings of the world's major car dealerships show, the days when passenger car diesel engines were reduced copies of units installed on heavy trucks are a thing of the past. The well-known Volkswagen concern, which developed the 1.9 TDI engine, was especially successful in the production of such engines. To date, it ranks first and is considered the most balanced in terms of dynamics and power.
Thanks to the latest engineering solutions, in particular, an updated turbine and an increase in pressure in the combustion chambers, managed not only to achieve unique environmental performance, but also to reduce. Moreover, the power remained at the same level (90–120 hp). The newest cars in the Passat series are now equipped with the highest performance engine (BlueMotion package). Fuel consumption is 3.3 liters per 100 km.
Diesel winners of the car market
The second place is occupied by a modification of the engine with three turbines, owned by the German company BMW. The first time this unit was introduced a few years ago. It has 6 cylinders and, having a volume of 3.0 liters, is capable of developing a power of 381 hp. With. Complete with these engines latest cars 5 and 7 series, as well as heavy crossovers with X5 and X6 indices. Its modification is provided with convertibles having serial number 6. True, it has two turbines, due to which the power is reduced to 313 hp. With.
Not so long ago, cars were presented to potential buyers, whose engines have four turbines, and with a torque of 800 Nm, the power will be within 390–406 hp. With.
A car with a four-turbine engine
The third place in our rating was taken by the American company of industrial diesel engines Cummins, which released a super-powered engine on order. famous company Dodge. In fairness, it should be noted that overseas manufacturers did not pay too much attention to diesel engines, preferring to develop gasoline ones. However, the recent increasing demand for cars with units that consume diesel fuel has forced them to pay attention to the production of diesel engines.
The model proved to be quite powerful (240–275 hp), but in an attempt to occupy the “diesel” niche in the market, the Americans were cunning and passed off as their development by the Italian concern Fiat. The Maserati Ghibli was equipped with a model of such an engine, but due to the crisis, production was given to US industrialists.
This engine was recognized not only as the most environmentally friendly, but also the most innovative: in its production, metals used in the space industry and plasma fuel filters were used. The fact that the engine took only third place is a "merit" of a narrow focus. It is installed only on sports cars and pickups. dodge ram. In terms of efficiency, it can give odds to its competitors: the consumption is only 8.5 liters per 100 kilometers.
Who is not far behind the top three?
The Koreans, who broke into the global automotive market 20 years ago, not only managed to take their rightful place on it, but also “move” the Japanese giants in the ranking. Having come a long way "from electric kettles to mining trucks”, they also do not want to miss their benefits, which promises an increased demand for cars equipped with diesel engines.
As always, Asian manufacturers acted very cunningly: not wanting to overhaul production and compete with Europeans and Americans in the power of units, they managed to create a 1.7-liter engine that can produce 110–136 hp. With. Do not rush to wrinkle your nose contemptuously! With such rather modest (compared to products from other manufacturers) data, Hyundai's diesel engine has such an incredible torque that it is not inferior in dynamics gasoline units having a capacity of 150-170 liters. With.
I must say that such a unit is equipped Hyundai car i40 supplied to the European market. In Korea, diesel engines have somehow not found wide application (or the wave of “fashion” has not yet reached there), and therefore they are still installed only on export cars. Recently, the same unit appeared on a crossover with the ix35 index, and now it is equipped with such popular cars like Grandeur and Sonata. Fuel consumption, however, is more than that of competitors, but the Koreans do not seek to surprise anyone. Their mission is to deliver reliable workhorses capable of average fuel consumption, in this case 5.5 liters per 100 km.
"Squeezing out" enough power from cars and having won its cell in the market, Japanese concern Toyota now makes no sense to prove something to anyone. The concept that manufacturers have thrown all their efforts into is ecology and economy while maintaining sufficient power. And they succeeded. Creating an engine for their compact car named Urban Cruiser, they thought that the residents of megacities would not only be convenient to move around the city, but also that a “calculator” would not turn on in their heads, calculating fuel costs.
One of the smallest diesel units to date is a 1.4 liter engine with a power of only 90 hp. With. This is the fifth place in our ranking. Such parameters, however, do not interfere with the creation of torque, which makes it easy to “pull” an all-wheel drive car. The consumption of diesel fuel, depending on the mode of travel, ranges from 4 to 6 liters per 100 km.
So which one is the most reliable?
Such a question is a bit naive, since this parameter depends on many factors, including driving style. But if you choose the best from the above list, then the reliability will be given to the Americans Cummins with a Dodge engine.
And it's not about power or fuel consumption per 100 km. Most likely, the materials used in production play a role. The cylinder block is made of high carbon cast iron, able to withstand not only high pressure, but also significant temperature regime. And its pistons are made of a special aluminum alloy, which is used in the details of spacecraft. This means that they are able to withstand both long-term operation under extreme conditions, and sharp rise load when changing speed.
The engine is also equipped with a Common Rail fuel injection system, which, despite its rather capricious attitude to the quality of diesel fuel, not only significantly saves its consumption, but also plays a decisive role in reducing engine noise. It is with these engines that both sports cars and cars are equipped. off-road. That is, it is precisely those instances of the automotive industry, the operation of which takes place in extreme conditions, demanding from the motor not only unsurpassed power, but also impeccable reliability.
If we talk about the rating of cars that are suitable for Russian roads, it is best to pay attention to samples of Japanese production. Optionally, it will be Toyota (which, by the way, not a single Russian motorist has any complaints about the engine).
For our vast expanses, Mazda, Honda, Nissan or the newly revived Datsun will do just fine. The Subaru performed quite well.
The fact is that European cars equipped with a diesel engine are very sensitive to our diesel fuel, the cleaning quality of which leaves much to be desired. As numerous reviews of car owners show, japanese cars less prone to malfunctions during use diesel fuel, thanks to numerous cleaning devices, electronic devices and built-in preheaters that do not allow diesel fuel to solidify at low temperatures.
Have Japanese manufacturers reliable diesel engines. And what is the most reliable diesel engine among all reliable in Japan?
Let's look at the most common modern diesel engines in the Japanese car industry.
What are these diesels, what are the weak and strengths Japanese diesels. They now dominate mainly in Europe, but quite often began to appear in Russia.
But, unfortunately, they also have problems when their runs exceed one hundred thousand kilometers, and even some up to one hundred thousand.
Supply Caution diesel engines from Japan due to their capricious attitude to fuel. Their fuel system rather weak to the use of our diesel fuel.
Another problem is the availability of spare parts. There are practically no non-original spare parts from reliable manufacturers. Chinese ones appear, but their quality leaves much to be desired and does not at all correspond to Japanese quality.
Hence their very high price is dictated, much higher than for German spare parts. There are many factories in Europe producing spare parts decent quality and at prices significantly lower than the original ones.
The most reliable diesel engine from Japan
So what is the most reliable diesel engine from Japan? Let's rank the TOP 5 of the best diesel engines.
5th place
In fifth place, you can safely put the 2.0-liter Subaru engine. Four-cylinder, turbocharged, boxer, 16-valve. Common rail intake system.
It must be said that this is the only boxer diesel engine in the world.
A boxer engine is when mutual pairs of pistons work in a horizontal plane. In this arrangement, careful balancing of the crankshafts is not required.
The weaknesses of this engine are a two-mass flywheel, it failed even up to five thousand kilometers. Cracking crankshaft, until 2009, crankshafts and shaft bearings were destroyed.
This engine is very interesting in its design, with good performance, but the lack of spare parts for such engines nullifies its advantages. Therefore, he Japanese series diesel engines take the fifth place of honor.
4th place
We will lift to the fourth place Mazda engine 2.0 MZR-CD. This diesel engine has been produced since 2002, and installed on Mazda car 6, Mazda 6, MPV. It was Mazda's first Common Rail engine.
Four cylinders, 16 valves. Two versions - 121 hp and 136 hp, both of which developed a torque of 310 Nm at 2000 rpm.
In 2005, it underwent modernization, with an improved injection system and a new high-pressure fuel pump. Reduced compression ratio and adaptation of the engine with a catalyst for the emission of harmful gases. Power became 143 hp.
Two years later, a version with a 140 hp engine was released, in 2011 this engine disappeared from the line of installed engines for unknown reasons.
This engine calmly nursed 200,000 kilometers, after which it was necessary to change the turbine and the dual-mass flywheel.
When buying, you should carefully study its history, but it is better to remove the pan and look at the oil sump.
3rd place
Also a Mazda engine, Mazda 2.2 MZF-CD. The same engine of increased, but increased volume. Engineers tried to eliminate all the jambs of the old two-liter engine.
In addition to the increased volume, the injection system has been modernized, another turbine has been installed. On this motor, they put piezo injectors, changed the compression ratio and radically changed particulate filter because of which there were all the problems of the previous model of the two-liter engine.
But the worldwide fight for the environment, both in Europe and Japan, adds gimoroya to all engines, and a system is installed on this one, with the addition of urea to the diesel fuel mixture.
All this reduces exhaust emissions to Euro5, but as always, in Russia this adds problems to all modern diesel engines without exception. This is simply solved by us, the particulate filter is thrown out and the afterburning valve of the unburned exhaust is turned off.
The rest of the engine is reliable and unpretentious
2nd place
Toyota 2.0/2.2 D-4D engine.
The first two-liter Toyota 2.0 D-4D CD appeared in 2006. Four-cylinder, eight-valve, cast iron block, timing belt, 116 hp The engines came with the "CD" index.
Complaints about this engine were very rare, they all came down to injectors and the recirculation system. exhaust gases. In 2008, it was discontinued, and a new one was launched instead, with a volume of 2.2 liters.
Toyota 2.0/2.2 D-4D AD
They have already begun to make a chain, there are already 16 valves for four cylinders. The block began to be made of aluminum with cast-iron sleeves. The index of this engine became "AD".
The engine is available in both 2.0 liters and 2.2.
The best reviews about such an engine, and good returns, and low fuel consumption. But there were also complaints, the main one was the oxidation of the aluminum head at the point of contact with cylinder head gasket, approximately in the period of 150-200 thousand km. run.
Replacing the head gasket does not help, only grinding the cylinder head and block, and this procedure is only possible with the removal of the engine. And such a repair is possible only once, the motor will not withstand the second grinding of the head and block, the depth will be critical with the possibility of meeting the valves with the head. Therefore, if the motor passed 300-400 thousand kilometers, with one grinding, it is only for replacement. Although this is a very decent resource.
Toyota in 2009 solved this problem, with such malfunctions, they even got me under warranty for new engines at their own expense. But the problem is very rare, but it does occur. Mostly for those who are not weak on the strongest version of this 2.2-liter engine model.
Such engines are still produced and installed on various models cars: Raf4, Avensis, Corolla, Lexus IS and others.
1 place
Diesel engine Honda 2.2 CDTi. The most reliable small diesel engine. Very productive and very economical diesel engine.
Four-cylinder, 16-valve, variable displacement turbocharged, common rail injection system, sleeved aluminum block.
The injectors are used by Bosch, not capricious and expensive Japanese Denso.
The predecessor of this engine was built back in 2003 with the marking 2.2 i-CTDi. He turned out to be very successful. Trouble-free, dynamic and economical in fuel consumption.
The modern Honda 2.2 CDTi engine in question appeared in 2008.
Of course, typical malfunctions did not pass, but all of them were extremely rare. Exhaust manifold cracks, but they occurred in the first releases, the Japanese reacted and this was not observed in subsequent releases.
Sometimes there were malfunctions of the timing chain tensioner. Also, sometimes the play of the turbine shaft appeared prematurely.
All of these failures arose from excessive constant loads and poor maintenance.
Honda installed this engine on Honda models Civic, Accord, CR-V and more.
Of course, this engine has the smallest number of failures and breakdowns in relation to all other engines of Japanese automakers.
We put him five points out of five, assign him the first place of honor and wish you to have a similar one on your car.
