The 1.8 engine Lada Vesta SV Cross is the heart of the domestic station wagon, which is one of the most important and significant parts. From this article you will learn absolutely everything about the 16-valve 1.8 Lada Vesta SV Cross engine with index 21179 - its strengths and weaknesses, characteristics, design, etc.
Let's start with a short excursion into history. About 5 years ago, a completely new 16-valve engine with index 21179 appeared on the AvtoVAZ conveyors. Outwardly it was similar to its predecessors, but inside it was very different from them.
Let's compare technical characteristics
If we compare the technical characteristics of these two engines, then in terms of choice, the advantage will be on the side of the 1.8 liter engine (model 21179): 122 horsepower versus 106 for the 1.6 liter (model 21129), acceleration to 100 km/h in 12.1 s (for the “rival” "for 12.8), the maximum speed that a car can develop is 188 km/h for a 1.8-liter engine, 178 for a 1.6-liter engine. Thus, if you are more interested in quality characteristics, then you should definitely pay attention to the first option engine. However, on the other hand, it turned out to be less practical in terms of savings.
What kind of oil is recommended for Lada Vesta?
Regarding savings, the manufacturer recommends filling in SAE 5W30 or SAE 5W40 oil of domestic brands:
The plant calls foreign manufacturers an alternative oil for Vesta with the characteristic 5w30:
- Mobil (5w40 is also allowed, and for new cars 0w40);
- Motul Specific DEXO s2;
- Shell HELIX HX8.
It is precisely with its lower power and volume that the 1.6-liter engine turned out to be a more economical option, because its fuel consumption is slightly lower than that of its opponent: 9.3 liters - in the city; 5.5 – on the highway; 6.9 – in mixed mode (versus 10.2/6.5/7.5 for the 1.8-liter, respectively).
Now let’s move on from dry and boring numbers to a more lively “interior”. As for the drive, there are as many as three options: the larger engine has a timing belt from the German company INA (and as you know, there is no doubt about the quality of German products), the standard 1.6-liter power unit has a regular timing belt, but There is also a similar engine from the Nissan concern H4M (with a power of 110 hp, many sources indicate 114 hp, but this is incorrect), on which a chain is already installed.
In the latter case, we can talk about the “golden mean” between quality and efficiency. Although, in the case of the practicality of the drive, the Nissan engine “jumped ahead” of both of its brothers - here you can save on consumables (the chain is, however, more expensive, but it lasts much longer, there is no possibility of bending the valves).
Renault-Nissan H4M-HR16 DE
The only foreign-made internal combustion engine in the Lada Vesta is the H4M-HR16 DE, manufactured by the joint company Renault-Nissan. Its main difference from the two above-mentioned engines is the absence of a timing belt. Instead, a chain is installed, which is much more reliable and cheaper in terms of use and repair. Engine Specifications:
- volume – 1.6 l;
- power – 114 hp;
- drive and timing – chain instead of belt;
- torque 153/4400;
- weighs 109.1 kg;
- electronic starting system;
- distributed injection;
- accelerates to 100 km/h in 12.2 seconds;
- resource 250 thousand km.
This engine consumes 92 and 95 gasoline and methane. The standard consumption in a populated area is 8.2 liters, on highways 5.4 liters, and in mixed driving 6.3 liters. Like its brothers, it adheres to Euro-5 toxicity standards. The H4M-HR16 DE engine is the most expensive among all three installed on Vesta, but also the most reliable in operation. Powerful, dynamic, comfortable, at the same time it “eats” little fuel. Distinctive features of the engine also include increased piston sizes and crank radius, improved, more economical oil passages and some other upgrades.
Perspective
It should be noted that the power unit from the Nissan concern is superior to our domestic engines both in many quality and technical characteristics and in terms of efficiency (more reliable, more durable and uses less oil). Surely, not everyone needs exactly record numbers from a car and its engine - most car owners are looking for the most advantageous combination of reliability, practicality and efficiency, and therefore in this case it is worth paying attention to the Lada Vesta with a Nissan engine.
But there is one thing, the installation of the imported H4M engine has been postponed indefinitely, apparently due to the rise in price of the model and, as a consequence, the recoupment of such an upgrade is not profitable.
There is good news, on October 20, 2022, information was received that AvtoVAZ is testing another engine on the Lada Vesta, this is a 1.4-liter gasoline turbo engine from Renault and 150 hp, we’ll find out how this will end a little later.
But in order not to further mislead the public, it is necessary to mention in a few words the combination of these engines with various types of transmissions. So, the 1.8-liter engine is installed on all three types of gearboxes used in Vesta: robotic, mechanical and automatic. A conventional domestic 1.6-liter power unit is combined with a robot and mechanics. The Nissan engine is also installed on all three types of gearboxes. As most car owners understand, a car cannot develop its full engine potential with a robotic gearbox. But the choice of gearbox remains beyond the scope of this article; among the engines, it is worth noting the 1.6-liter Nissan concern due to its higher reliability and efficiency.
Today, dealers offer only 4 versions: - 1.6L 106 hp with a 5MT gearbox and 5ST AMT - 1.8L 122 hp with a 5MT gearbox and 5ST AMT
Video comparison test of 1.6 versus 1.8 engine on Vesta:
AvtoVAZ is developing its 16-valve engines gradually, that is, step by step. When the updated Kalina family appeared in 2013, buyers were perplexed as to why they offered a 106-horsepower engine in manual versions, which differed little in design from the usual Priora engine.
The new engine was equipped with resonant supercharging, and it seemed that its presence would only have disadvantages: reliability was reduced, there was no way to connect the cable drive. But it turned out that the new engine was no worse than its predecessor: the mass air flow sensor often breaks down, and the DBP and DTV sensors almost never. There is no MAF sensor in the design of the 27th engine, which is the secret of increased reliability.
Why was the 27th engine replaced with the 29th?
The VAZ-21127 engine was good for everyone, except for one thing - it complied with Euro-4 standards. For Vesta sedans produced since November 2015, this option would not be suitable. It was necessary to solve a difficult problem: to improve the environmental class without increasing the volume and without losing power. And as a result, a new family of 16-valve engines appeared in the VAZ arsenal. We are talking about motors 21129 - they really meet the latest environmental standards.
The first Vesta engine, produced by VAZ
To move to the Euro-5 standard, engine 21127 had to be modified:
- The resonant intake system, as well as the exhaust system, have been completely redesigned;
- The ECU controller (ECM) has received new firmware - even the algorithm that regulates the volume of the resonant chambers has been changed;
- Engines 21127 and 21129 have slightly different compression ratios - 11.0 versus 10.45;
- The engine suspension was also improved: it became possible to mount it on a subframe.
Specifications
All parameters related to motor 21129 are listed in list form:
- The working volume is 1.596 l;
- Compression ratio – 10.45;
- Power (nameplate value) – 106 hp. at 5800 rpm;
- Maximum torque – 148 N*m at 4200 rpm;
- Maximum shaft speed – 6200 rpm;
- Oil change intervals – 15,000 km;
- Crankcase volume – 3.2 (2.9) or 4.4 (4.1) liters, the first option is for the “AMT” gearbox;
- Oil viscosity – from 0W30 (0W40) to 20W40 depending on temperature;
- Engine life is 200,000 km.
For one liter of fuel consumed, there is up to 3 ml of oil. These figures are indicated in the VAZ documentation. This means that 240-250 ml will be needed per thousand km. engines (HR16DE) consume twice as much.
Power and torque depending on frequency, rpm
Now let's analyze what is shown in the graph. The motor develops a force exceeding 130 N*m in a wide range: from 2300-2400 to 5900 rpm! This means that the traction will be very “elastic”, which is exactly what is needed for configurations with “AMT”.
At low speeds, not exceeding 1800 rpm, the tractive effort value “tends to zero,” which is typical for most 16-valve engines. But we are talking about what kind of engine is in the Lada Vesta - this is not an SUV, where “low-end traction” is very important. Cover with your hand the part of the graph located in the first quarter - you will get the load curve of the “ideal engine”.
Which gasoline to fill?
A few words about the fuel used. For engines of the 21126-21127 family there was a strict ban: you can pour 95 gasoline, but not 92 gasoline. But knowing what kind of engine is being installed on the Lada Vesta now, the ban can be ignored: the compression ratio has decreased, and this means that the octane number can also be reduced.
The documentation for the engine in question specifies gasoline with an octane rating of 95. Other options are not considered.

Under the hood of the Lada SV Cross 1.8 there is an engine 21179
Engine 1.8 Lada Vesta resource
The service life of the Lada Vesta 1.8 engine is about 200 thousand km.
Even earlier, in Togliatti there had already been attempts to assemble a 16-valve 1.8, but they were unsuccessful. Although the engine itself was assembled on the basis of the 21124 that was already available at that time, which today is considered one of the most successful VAZ engines. The previous 1.8 received the index 21128. But it never went into production due to an unsuccessful design, increased oil consumption and an extremely short service life. This engine barely reached 100 thousand kilometers and was already in need of major repairs.
The subsidiary produced small-scale Ladas with this engine, but only a few have survived to this day. In particular, 1.8 engines from Super-AUTO were in Lada Priora cars, but this modification never gained popularity, so production was curtailed, postponing 1.8 until better times.
Car with internal combustion engine “21129”, test drive on video
Good characteristics, so far I have noted 2 disadvantages for myself: oil consumption of 250 ml per thousand km and recommendations not to fill with 92-grade gasoline (after all, it is more profitable financially, and not all gas stations can find 95-grade in our city).
Vesta 92 is allowed. On the 127 engine the 95th
Well it turns out if 250 ml. for a thousand, then at 12 thousand I have about 1 liter of oil left? Is the oil dipstick lying?
This plant has secured itself. In order to refuse the warranty if something happens. In general, almost 3 liters from replacement to replacement, that’s crazy.
I have 6 pots (3.3 liters), 250 thousand miles, 18 years old car. Oil consumption is about 500 ml per 15 thousand km. From replacement to replacement, there is still some stock left. A 250 ml. per thousand, this is not a minus, this is firewood!
VAZ pleases with his Vesta in everything and even in the choice of engine for the new Vesta! The engine is, of course, powerful and has a lot of power, but if you want to drive fast and so that the car doesn’t suffocate, then you need to pay money for gasoline and oil! Although this engine is more economical than in foreign cars...
))))) more economical. FUNNY, my 1.7 with 130 horses eats about 8 or even less 95 liters in the city, on the highway within 100 km/h it eats 4.5-5.5 liters…. and a maximum of a liter of oil per 10,000, so the mileage on the engine is already more than 260t.km. …..
“Although this engine is more economical than on foreign cars...”
Is it really “powerful”? Is it really “more economical”? I have a 3.3 liter engine, the weight of the car is 1905/2460 kg - it eats 8 liters on the highway. So this engine has been produced since 1991! And there will be fewer valves... And a V-shaped engine... And the car is 18 years old... Do you want a comparison closer to Vesta? I once had a 1.6-liter Opel Cadet (sedan, 1987) - the consumption was 5.6 liters on the highway, although I didn’t drive quietly then.
The characteristics are quite good - I have become closer to my classmates in terms of performance. Although from a tax point of view the previous engine option was preferable.
There's something wrong with the oil. After 8000 km, oil consumption should be
2 liters I drove 8000 km without adding oil. Maybe a mistake, but in fact 250 ml per 10 thousand km?
Thank you for your comment, we will check with the AvtoVAZ representative and we will definitely answer you!
Is the vestemotor really disposable?
Of course it's a mistake! (or the machinations of vasophobes). The first car I had was a Moskvich AZLK 2140; its operating manual indicated oil consumption of 80 g/1000 km, and when this figure increased to 200 g/1000 km, the engine was considered worn out and required major repairs. How can oil consumption be so high on a new modern car? I have only driven 2000 km on my Vesta so far, I constantly monitor the oil, and the level has not dropped either.
No increase in agility
It’s a paradox, but the rear of the body in the Vesta is better soundproofed than in the Solaris. He has bare metal around the spare tire, and in the VAZ station wagon there are mats glued on here, albeit made of batting, the reserves of which, it seems, have not dried up at the Tolyatti plant since Soviet times. Nevertheless, they exist, and this is reflected: on the move, the Vesta is quieter than the Solaris, although, perhaps, this difference can be attributed to the incredibly noisy tires with low rolling resistance, which the test sedan was shod with .
But it has the advantage of a faster engine. With the same displacement, it produces a dozen more horses, and all of them are easy to climb. And we have Vesta with a new unit - Nissan's, with 113 horsepower, the same one that is familiar to many from the Qashqai, Almera and Juke models. The character of this unit is dual.
On the one hand, in urban conditions, Vesta pleases with its dynamics. In dense traffic on the streets and avenues, it seems quite “alive”, at least not inferior to its numerous competitors. It’s a different matter on the highway - where does the speed go? Actually, nowhere, you just have to “spur” our station wagon and it will respond. That is, at 2000-2500 rpm we just roll, and at 3000 we finally begin to accelerate, but it’s better to reach 4000 rpm, that is, the passport level of maximum torque. It is clear that this takes time, seconds and seconds. 2-3 with Vesta will definitely lose to Solaris in acceleration from 80 to 120 km/h.
I check with a stopwatch: in this range, the VAZ station wagon accelerates in automatic mode in about 10 seconds. Maybe manual gear selection will help the dynamics? Not much. I choose the fourth “stage” - the result is the same, up to tenths of a second. On the third I improve it extremely slightly - by 0.3-04 s. At the same time, by 120 km/h the tachometer needle almost reaches the red rev zone. At the fifth and sixth stages I don’t even check the dynamics, although, judging by the city mode, the fifth “level” of Vesta is more efficient than that of Solaris.
Perhaps the delay is caused by the new transmission? After all, with a Nissan engine we get a Japanese JATCO variator. Alas, buyers of VAZ cars, dissatisfied with the “robot” AMT, did not wait for the automatic machine. Will the CVT please them? After all, a priori there are complaints about him.
Firstly, according to statistics from independent car services, its service life is about 150-170 thousand kilometers. Then, inevitably, serious repairs follow, which can be brought about by a “ragged” rhythm of movement with sharp accelerations and braking. Secondly, for normal service during this period, you should not only not neglect regular maintenance, but also use special oil in the device.
By the way, about the “contents” of the variator. Vesta’s on-board computer does not measure the temperature inside it, but it would be nice to do so. However, the breather, which on the test car was mounted on a flexible hose upward relative to the gearbox housing, protects against its excessive increase. But as it was removed, it was fixed in the holder so weakly that it fell out during movement... The unit is shown in the photo. If the factory workers have not done this, the simplest solution suggests itself: tighten the head of the breather to the holder with a plastic cable tie.
It’s such negligence that spoils the impression of a quite nice and practical car. Moreover, they are raised, as they say, onto a shield and presented as fatal flaws. They blame the Togliatti factory workers, who supposedly inherited the “best traditions” of Soviet assembly, and even the place on which the Volzhsky Automobile Plant was built. In my opinion, there is absolutely nothing criminal in such little things, and my personal impression of the “Vest” with the SW index, on the contrary, consists of positive aspects, for example, the organization of the same trunk. And fixing the breather yourself, in my opinion, is simply interesting. Well, those who wish can complain about a “defect” by contacting the dealership, and they will probably fix it under warranty. My three-year experience of owning an Xray suggests that VAZ is now okay with this.
Comparative characteristics table
The differences are: the volume of all combustion chambers in 21129 is 178 cc smaller and amounts to 1596 cc, therefore the 1.8-liter engine, in addition to more horsepower, also has a higher torque - 170 Nm versus 146 Nm.
The dynamic properties also differ: the highest speed of a car with a 1.8 engine. liter is 180 km/h, acceleration time to 100 km/h is 11.5 seconds. The 1.6 engine is inferior to the more massive version both in highest speed by 8 km/h and in acceleration from 0 km/h to 100 by 1.4 s.
KEY-DOP
It consumes fuel in the smallest quantity 21129 - in the city 9.7 liters per 100 km, in the suburbs 6 liters, on mixed roads - 7.5 liters.
21179 has a higher consumption in the city by 1 liter than the 1st option, in the suburbs on a mixed road - by 0.4 liters. It takes a lot of fuel per 100 km.
Lada Vesta SV Cross - which engine is better? Comparison 1.8 and 1.6 (21179 and 21129)
When choosing a car, it is not enough just to decide on the color, equipment and additional functions. It is also important to decide on the technical parameters - engine and gearbox. As you know, only two types of engines are installed on Lada Vesta SV Cross cars - gasoline 21129 and 21179. Let's decide which engine is better than the Lada Vesta SV Cross?
We have already reviewed each of the engines in detail on our website. Therefore, you can always go to the necessary materials and study the 1.6 and 1.8 engine in more detail. And in our article we will compare these two motors.
So, if you turn to the LADA.RU website, you can see this picture, which shows the most important differences between the Lada Vesta SV cross 1.8 and 16 engines.
Externally, these motors are practically no different from each other, but internally they have differences. If we omit all the technical points, the main differences will be the volume of the combustion chamber, power and torque. Acceleration to 100 km/h, maximum speed and fuel consumption will also differ. It is these indicators that are primarily important for the end consumer. And the design of the motor itself is no longer so important for the buyer. But we will get to that in our article.
So, to understand which Lada Vesta SV Cross engine is better, you need to compare all the data. For this we will use a pivot table.
| Engine 1.6 l 106 hp (21129) | Engine 1.8 l 122 hp (21179) | |
| power, hp / kW | 106 / 78 | 122 / 90 |
| Max. torque, nm | 148 | 170 |
| acceleration to 100 km/h, sec (amt) | 12,6 | 11,2 (13,3) |
| Max. speed, km/h (amt) | 172 | 180 (181) |
| FUEL CONSUMPTION, L/100 KM (AMT) | ||
| in the city | 9,7 | 10,3 (10,1) |
| mixed | 7,5 | 7,9 (7,7) |
The 1.6 liter engine is weaker than the 1.8 liter by 16 hp. and 12 kW. Accordingly, the 1.8 engine has more torque - 170 Nm versus 148 Nm for the 1.6. Yes, by the way, the volume of the combustion chamber differs by 178 cc.
The dynamic performance of the Lada Vesta SV Cross engines is also different. Acceleration to 100 km/h for the 1.8 with a manual transmission is 11.2 seconds, for the 1.6 with the same mechanics it is 12.6 seconds, and for the 1.8 with a robot it is 13.3. In the latter case, the robot does not show any good results. But you don’t have to constantly pull the gearshift knob. But that’s not what we’re talking about now; we’ve already written about the Lada Vesta SV Cross robot in one of our articles.
As for the maximum speed, 21129 accelerates to 172 km/h, and 21179 with manual transmission - up to 180, and with AMT - up to 181 km/h. In this case, the difference in maximum speed is quite insignificant.
In terms of fuel consumption, both engines also show different results. 1.6 in the city consumes 9.7 l/100 km and 7.5 l in the combined cycle. And the 1.8 engine consumes 10.3 liters in the city (10.1 on AMT) and 7.9 in the combined cycle (7.7 with a robot). Thus, the most economical is the motor with index 21129.
The cost of the Lada Vesta SV Cross with a 1.6 and 1.8 liter engine is not much different. The Luxe package with a 1.6 liter engine will cost the buyer approximately 770,000 rubles, and with a 1.8 liter engine - 795,000 rubles. The difference, as you may have noticed, will be only 25 thousand rubles. But there is one significant drawback. If you still decide to take the 1.6 liter engine, you will have to be content with the LUXE package. If you need richer equipment, then you will no longer have a choice - only 1.8 liters.
To understand which engine is better in the Lada Vesta SV Cross, it is more correct to refer to a comparative review of these two engines. Let's see all the details in the video:
>
There are no longer any global differences between these two engines. Their design is approximately the same. Structurally, these are the same motor. We can say that these engines are like two twin brothers. With one significant difference - 21179 has a redesigned CPG. Namely, the shape of the crankshaft, connecting rods and pistons were changed. Thus, due to the piston stroke, it was possible to increase the volume of the combustion chamber. The engine control program has also been redesigned. As a result, we received more power with all the ensuing “consequences”.
There are also many reviews on the Internet that the 1.8 engine eats oil. This is true on most machines. Alas, this is such a characteristic feature of this motor. But there are not the best reviews for motor 21129 either. Many complain about the weak compliance and insufficient power of this power unit. In this case, this is only a subjective assessment and cannot be refuted or agreed with. And in general, both engines are quite resourceful and problem-free. What should you choose? Decide for yourself, but I hope this article will be useful to you and help you with your choice. Thank you for your attention and see you again.

Engine 1.8 Lada Vesta resource
The service life of the Lada Vesta 1.8 engine is about 200 thousand km. He is very far from becoming a millionaire, and no one makes such engines now because of the economic component.
However, it all depends on many factors, the most important of which is your attitude towards the car and your driving style. If you maintain this engine in a timely manner and use high-quality consumables in the form of oil and filters, and also do not constantly turn up the speed to the red zone, then this engine can cover the entire 400 thousand km.
Advantages and disadvantages of the 1.6 engine
The 1.6 and 1.8 engines installed on the Lada Vesta SW Cross have their advantages and disadvantages. When choosing a car, you need to pay special attention to the properties of its unit, because the quality of the trip and the likely monetary costs of repairs in particular depend on its reliability.
Main advantages:
- Complies with European standards;
- Complies with environmental standards;
- The engine contains hydraulic compensators that smooth out the shock load;
- Time-tested design.
Disadvantages:
- Hydraulic compensators sometimes knock immediately after starting for a certain number of days;
- Not the most economical;
- Over time, engine oil is likely to develop.
