Lada Vesta SV Cross - which engine is better? Comparison 1.8 and 1.6 (21179 and 21129)


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.

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.

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).

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.

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.

DIMENSIONS OF LADA VESTA

It was not for nothing that Bo Inge Andersson said that in terms of size, the Lada Vesta will be one of the leaders in the class, which will largely ensure its popularity. That’s right, strictly speaking, the car is difficult to unambiguously classify as segment B, since it is at the junction of classes B and C. The length of the sedan is 4,440 mm, with a width of 1,764 mm and a height of 1,497 mm, and this is noticeably longer than the Hyundai Solaris (4,375 mm, 1,700 mm and 1,470 mm), which is one of the main competitors of the Russian car.

The wheelbase of the Lada Vesta is 2,570 mm, and the track of the front and rear wheels is slightly different - 1,495 mm and 1,502 mm, respectively. The ground clearance of the new product is traditionally higher than that of foreign cars and is equal to 171 mm under the crankcase of the power unit, provided it is fully loaded, and also 144 mm, subject to change under the engine mudguard. This, together with a front overhang of 860 mm and a rear overhang of 915 mm, as well as approach and departure angles of 16.6° and 14.2°, provides the ability to confidently drive on country roads, which is important for residents of small towns.

The luggage compartment of 480 liters of usable volume is also one of the most spacious in the class, and the payload of 487 kg allows you to take a lot of luggage “on board”. Vesta's curb and gross weights are 1,178 kg and 1,653 kg, respectively. But the distribution of curb and total weight along the axles is different. In the first case it is 60/40, and in the second – 52/48. Regarding towing a trailer, the permissible weight for a device equipped with brake mechanisms is 900 kg, and for one without brakes - only 450 kg.

Engine Specifications 21179

We invite you to take a closer look at this engine. Below we describe all the main parameters that the 1.8 engine on the Lada Vesta Cross has.

  • index - 21179;
  • working volume - 1.8 l;
  • engine power - 122 hp, which is achieved at 6050 rpm;
  • torque - 170 Nm, at 3750 rpm;
  • environmental class - Euro5;
  • fuel type - AI92 or AI95;
  • average fuel consumption per 100 km;
  • Manual Transmission;
  • urban cycle - 10.7 l;
  • suburban - 6.4 l;
  • mixed cycle - 7.9 l;
  • automatic transmission;
  • urban cycle - 10.1 l;
  • suburban - 6.3 l;
  • mixed cycle - 7.7l.

The maximum engine life, according to the passport data, is about 200 thousand kilometers.

Motor "VAZ-21179"

This version of the power unit for Vesta is the first of its kind, because its volume is still the largest - 1.8 liters. Some experts are inclined to believe that the manufacturer will equip the long-awaited new product with this unit – the Vesta Cross station wagon. This engine is available with a 5-speed automatic transmission. The assembly of the unit is carried out using a selective method.

Now let’s take a closer look at the technical parameters and other important aspects specific to this motor.

  1. From a 1.8-liter volume, the developers managed to squeeze out 122 “horses” - this is real power.
  2. The engine is designed to consume 95 gasoline, and the level of exhaust toxicity is within the regulated values ​​of the Euro-5 system.
  3. The torque reaches 170 Nm;
  4. Experts assure that the engine is capable of covering a repair-free range of 300 thousand km, which is rare for modern cars.

On a note! The level of fuel consumption of this engine is slightly higher than that of analogues used by the manufacturer for Lada Vesta. This is explained by the large volume of the working chambers of the unit. Many owners are not embarrassed by this situation, since the engine compensates for this conditional disadvantage with improved dynamic and speed capabilities.

Engine disadvantages

The engine entered mass production and installation with the launch of the new Lada Vesta. Enough time has passed since then, during which car owners and experts have identified a number of the most common breakdowns. These include:

  • beating of hydraulic compensators. This problem is not new for AvtoVAZ. Quite often, 16-valve engines produced by a domestic manufacturer suffer from this “sore”. It appears as a result of the use of unsuitable oil or insufficient volume of oil directly in the engine.
  • increased oil consumption. Another problem that migrated to VAZ engines, migrated to the new engine with index 21179. As a rule, it can be solved only after replacing the connecting rod and piston group. It’s good if the car is still under warranty and the dealer will perform the procedure for free. If the warranty period has expired, the financial burden of replacement falls on the owner.

As for the rest of the engine’s operation, the overwhelming majority of owners have no complaints about it. The engine has proven itself on the positive side. Timely and correct maintenance is enough and you will not recognize problems with the engine for 150-200 thousand kilometers.

By the way, if you are afraid to take a Vesta Cross with an automatic transmission, then your fears are completely unfounded. As practice shows, the service life of such a box is quite comparable to the mechanical version.

What features does the VAZ-21129 engine have?

This engine can be equipped in a Lada Vesta car with either a manual or automatic transmission. The ancestor of this unit was the well-known VAZ-21127 engine, which is considered obsolete and does not meet the requirements of environmental standards according to the Euro-5 system.

The updated unit has modern options and progressive design features, which allows it to be compared with engines of foreign-made competitors. Among these features, experts include:

  • reduced compression ratio, allowing the use of fuel with a lower octane number;
  • modified exhaust system;
  • structurally redesigned intake system;
  • updated ECU firmware.

The appearance of the engine has also become more modern. The perimeter of the unit is “overgrown” with all sorts of sensors of the electronic control system.

Note that this version of the engine is most common in the “Comfort” configuration. The designers also took care of creating a sports variation of the car, where they placed a forced engine capable of developing 150 hp. With. The unit considered here served as the basis for such a “fiery heart”. What engines are installed in all versions of the model?

The engineers were able to achieve the indicated results by applying the following design solutions:

  1. Reduced losses due to friction in the cylinders. Here the idea of ​​reducing the thickness of both compression and oil scraper rings was implemented.
  2. Improvements to the exhaust system, where a structurally new resonator is used.
  3. Use of lightweight pistons made of a special aluminum alloy.

On a note! It has been proven by experience that the natural oil consumption in a VAZ-21129 engine is 3 ml per 1 liter of gasoline consumed. This means that approximately 25% of 1 liter of oil present in the engine will be wasted over a mileage of 1 thousand km. This is a good result, because in comparison with domestic engines, the power units of some foreign cars consume much more lubricant over the same distance.

Now let's look at the main characteristics and features of the VAZ-21129 power plant:

  • power, as already noted, 106 hp. With.;
  • the torque is 148 Nm;
  • It is possible to boost the unit to 150 hp. With.;
  • you should start changing the oil every 15 thousand km;
  • uninterrupted operation of the engine at any speed is partly achieved thanks to the use of a special damper system inside the intake manifold;
  • the working pressure value in the chambers (compression) is 12.5 atm;
  • predicted resource – 200 thousand km.

Which motor oil to choose?

In order not to make a mistake when choosing engine oil for Vesta SW Cross, as is the case with other cars, you need to clearly understand the conditions under which the car will operate. First of all, you need to choose the appropriate viscosity of the engine oil. The operating instructions say that the following types of oils are suitable for this engine:

And this is where the nuances mentioned above begin. So, for example, if the car is operated in colder regions, it is better to give preference to liquid oils: 5W-30 or 5W-40. And if the engine is new and has low mileage, it is allowed to use oil with 0W-40 ratings.

If you live in a warm region or use your car exclusively in the spring and summer, you can safely fill in 10W-40 and 15W-40 oils.

Next, you need to select the optimal quality class. Again, according to the operating instructions, it is recommended to use oils of at least SM class according to API or GF-4 according to ILSAC.

State of the valves when the timing belt breaks

Like any modern engine, the Lada Vesta SV Cross engine with a displacement of 1.8 and index 21179 is susceptible to this defect. Indeed, when the timing belt breaks, the valves in the engine become deformed. This happens mainly due to the fact that manufacturers strive to achieve greater power with the same engine size. To make this possible, it is necessary to lighten the connecting rod and piston group while simultaneously increasing the compression ratio.

With this approach, it becomes impossible to groove the pistons in order to exclude the possibility of them “meeting” the valves in the event of a direct belt break. Regardless of the nature of the breakdown, this means a broken timing belt, jamming of the pump and tension roller, you will be faced with a major overhaul.

Engine assembly materials 1.8 Lada Vesta SV Cross

Let's continue our analysis of the engine. Next, we suggest you take a more in-depth look at the parts from which this motor is assembled. Parts List:

  • The timing belts used in these engines are manufactured by Continental. The declared belt resource is 180 thousand km. How truthful this can only be learned from the owners of Vesta Cross SV or from our own experience;
  • Continental also supplies injectors. This model of nozzles has a longer life and increased performance;
  • valves from Mahle;
  • pump from GMB. Its resource corresponds to the timing belt and is the same 180 thousand km;
  • an oil pump from GMB is also used;
  • but the installed camshafts were manufactured by Toyota Tsusho. They compare favorably with the old ones in weight;
  • INA phase adjustment mechanism.

Distinctive features of the engine

Many car enthusiasts rightly note the external similarity of the 21179 engine with early examples of 16-valve VAZ engines and, in particular, with the 1.6 engine. However, it was possible to achieve a larger engine volume compared to 1.6 not by increasing the diameter of the cylinders, but by increasing the piston stroke in the previous cylinder. To realize the idea, it was necessary to remake the connecting rod and piston group and install a new crankshaft.

It is worth noting that the new engine uses variable valve timing, which was not present on any previously released version.

The oil and cooling passages have also changed significantly.

New injectors with increased performance, mentioned above, were needed due to an increase in engine displacement. In addition to them, it was necessary to install a new throttle valve and increase the volume of the oil pan to 4.4 liters. An increase in the volume of oil in the engine entailed the installation of a more efficient pump. The intake ports have also become larger.

It is worth mentioning a new method for reading mass fuel consumption. An absolute pressure sensor and an air temperature sensor are now responsible for this.

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.

Speed ​​characteristics of Lada Vesta Cross engines of 1.8 and 1.6 liters.

Engine performance readings clearly demonstrate the final performance. We note the high-quality settings of the manufacturer. The maximum torque of 170 Nm can be achieved at 4000 rpm. At the same time, at 5500 rpm, the engine produces its maximum 122 hp. With.

Video about maintenance and repair of the Lada Vesta Cross engine:

When choosing a car, you need to decide not only on the brand, color, appearance, but also the technical parameters of the car. Whether or not to operate a more powerful engine is preferable, only the driver can decide, because everyone has their own preferences. If the choice falls on the Russian Lada Vesta Cross, you will need to choose between 1.6 liter or 1.8 liter engines.

Comparison of prices and options

Prices for Lada Vesta Cross with 1.6 and 1.8 engines differ insignificantly - 770 thousand and 795 thousand Russian rubles in the “Lux” configuration. Unfortunately, the 21129 engine is available exclusively in this version; if you are interested in richer modifications, you will have to fork out for the 21179 engine.

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 attention to the characteristics of its power unit, because the quality of the trip and possible financial costs for repairs will 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.

Flaws:

  • Hydraulic compensators may knock for some time immediately after starting;
  • Not the most economical;
  • Over time, engine oil may develop.

Pros and cons of the 1.8 engine

This power unit cannot be safely recommended to anyone who has decided to buy a Lada Vesta Cross and has a few extra tens of thousands of rubles, since it is also not ideal, and has not only advantages, but also some significant disadvantages.

Main advantages:

  • Power and torque are noticeably greater than those of a smaller engine;
  • Smooth ride;
  • Confidently pulls a loaded car.
