The media learned new details about the creation of the next generation Lada 4x4 ("Niva"). According to Kolesa.ru, AvtoVAZ specialists are working on engine adaptation VAZ-21179 with a volume of 1.8 liters for the new Lada 4×4.
At the moment, it is known that the concept of the SUV style has not been approved, since the engineering solutions for the car platform have not been fully developed.
According to preliminary information, the new generation Lada 4x4 NG(New Generation) can become a completely new model. It is possible that Lada 4x4 NG will be based on the B0 platform, which AvtoVAZ has been entitled to use since 2008.
At the same time, it is possible that for some time two Niva will be produced simultaneously.
Earlier it was reported that the 4x4 NG should be put on the conveyor in late autumn and early winter 2017. First, the release of a three-door modification will be launched, and then (in 2018) a "five-door" will appear. There was also information that under the new president of AvtoVAZ, Nicolas More, the project could be revised or adjusted.
We disassemble the new 1.8-liter VAZ-21179 engine
For the first time, AVTOVAZ launches a 1.8-liter engine into a series, for the first time introduces variable valve timing and for the first time uses selective assembly on a conveyor. 1.8L engine ( 122 hp) outwardly does not differ much from the current VAZ sixteen-valve. But this is a new motor, and its own design. Start of production - in February 2016.
- Throttle valve - without mechanical drive.
- The collector is supplied by the Russian company Ecoalliance. The diameter of the input channels has been increased to 39 mm. The oxygen sensor bears the Bosch emblem.
- Crankshaft - with increased crank radius.
- The working volume of the cylinders has increased due to the greater stroke of the pistons.
- A reliable high-performance water pump is purchased from the Korean company GMB.
- For the first time on a VAZ engine, an imported GMB oil pump with increased productivity was installed.
- A new automatic toothed belt tensioner was used - with two rollers, from the German company INA.
- Lightweight connecting rod and piston group - manufactured by Federal Mogul.
- The fuel rail is from Continental. Nozzles - increased productivity, spray pattern optimized for the workflow of the new engine.
The 1.8-liter engine does not look much different from the current VAZ sixteen-valve engines. But this is a new motor, and its own design.
Main parameters:
- working volume - 1774 cm³
- power - 122 hp
- torque - 170 Nm at 3750 rpm.
The new motor is designed for Vesta, XRAY and Largus models. On the block of cylinders there is an additional platform for drawing a serial number. It is clearly visible when the power unit is installed longitudinally in the engine compartment. Got the hint? There is no official information yet, but it is easy to guess that we are talking about Niva. The cylinder block is unified with that used on the current 1.6‑liter VAZ‑21126, -21127 and -21129 engines. The same height and the same diameter of the cylinders. The differences are in the additional channels of the lubrication system, which ensure the operation of the phase regulator, and in the additional channels of the cooling system.
Throttle valve - without mechanical drive. The motor meets the requirements of Euro‑5.
The working volume was raised by increasing the piston stroke from 75.6 to 84.0 mm. Crankshaft - with an increased crank radius and other counterweights. To reduce friction losses, the diameters of the connecting rod journals of the crankshaft were reduced from 47.8 to 43 mm. The oil channels have become different - the so-called drilling from the neck to the neck allows to reduce the cost of production, and less chips and dirt remain in the oil channels. On the end of the shaft there is a mark of classes of main and connecting rod journals for precise adjustment of the liners in diameter, that is, for selective assembly.
Additional oil channels to the phase regulator are made in the cylinder head. Lightweight valves are from Mahle.
The cylinder block and crankshaft are produced at AVTOVAZ. But a lightweight connecting rod and piston group is purchased from Federal Mogul - Vostok (Togliatti). The piston skirt is graphite coated and the skirt has been reshaped to increase the contact patch. The rings are the same as on other motors of the family, only the oil scraper ones are chrome-plated. The height of the top land has been increased by 1.3 mm, and now the so-called compression height is 26.7 mm versus 25.4 mm for 1.6-liter engines. The price for increasing the stroke of the piston at the same height of the block is a reduction in the length of the connecting rod from 133 to 128 mm. The lower head of the connecting rod is made using the so-called discontinuous technology - like the current 1.6‑liter engines.
Crankshaft - with increased crank radius. The working volume of the cylinders has increased due to the greater stroke of the pistons.
Phase adjustment required modernization of the lubrication system. Indigenous bearings with an oil-distributing groove of variable section are installed - to reduce oil consumption. For the first time, a foreign-made oil pump appeared on a VAZ engine - the South Korean GMB. The performance of domestic pumps is 34–38 l / min at an engine speed of 6000 rpm, and GMB produces 54–60 liters. The pump body is aluminum, not cast iron. The cross section of the oil intake, of course, is increased. The aluminum sump of the engine crankcase has a flange for mating with the clutch housing, which increases the rigidity of the power unit. The volume of the oil sump is 4.4 liters versus 3.2 liters for the 1.6 engine.
The water pump is also Korean, with solid bearings and seals that guarantee reliability. It is better than serial VAZ ones: among other things, performance is higher. The plastic intake module is made by the Togliatti company Motor-Super. The gas-dynamic characteristics of the intake tract are optimized for the new engine. The advanced finning of the module made it possible to reduce noise. The engine management system does not work with mass air flow readings, but calculates parameters through temperature and pressure. Therefore, there is a slot for the corresponding sensor in the intake module.
Cylinder head. The camshafts are made in Korea. The drive disk and the phase sensor are clearly visible, allowing you to track the position of the intake shaft.
The cylinder head is of domestic production. The casting has additional channels through which oil enters the phase regulator, as well as sockets for the regulator control solenoid and phase sensor. A drive disk is fixed on the intake camshaft, tracking its position. Significantly redesigned water jacket for better cooling of the combustion chamber. In addition, the resistance to liquid pumping was reduced. The gas channels have been modified for better filling of the cylinders and intensification of the vortex motion of the air-fuel charge.
South Korean-made camshafts are supplied by Toyota Tsusho. They are hollow inside, and the cams are made by powder metallurgy. Such a camshaft is much lighter than the former, cast iron. Mahle valves are also lightweight, with 5 mm stems. Crackers, guides, valve stem seals - of the appropriate size. The purpose of the relief is to reduce the inertia of the system, which makes it possible to open the valve more quickly.
The camshafts are made in Korea. The drive disk and the phase sensor are clearly visible, allowing you to track the position of the intake shaft.
A hydraulic-type phase control mechanism is installed on the intake camshaft. Its design is traditional, but the dimensions are for our motor. The supplier is the German company INA. The shafts are driven by a toothed belt manufactured by Continental. According to factory specialists, it will serve 180,000 km.
The new motor weighs 99.3 kg. When tested on the bench, he demonstrated high fuel efficiency. Perhaps the supply of high-quality fuel from the company http://diztop-spb.ru/ affects - in some modes - it is a record holder among VAZ engines! The resource is 220,000 km, but with a caring attitude, up to 400 thousand pass. Another joy for future buyers: the engine can be refueled with AI‑92 gasoline. Of course, on the 95th, the power indicators will be higher, but here it’s up to the owner to choose - to save or “anneal”.
Phase regulator (INA) and regulator control solenoid.
It seems that not only the phases in the gas distribution mechanism have shifted, but also the attitude towards the consumer. By the way, the potential of the new motor has not been exhausted. Perspective - the second phase regulator, now on the exhaust valve shaft. And on this, I am sure, the development of this engine will not end.
Lada 4 × 4 Urban - is a modernized version of the legendary Lada 2121, which is still called NIVA in the common people. The main differences from the classic model are the presence of plastic bumpers, an upgraded suspension, air conditioning and full power accessories, which include electric mirrors and power windows. Although this car has been produced not so long ago, it is now possible to highlight several problem areas that future owners need to know about before buying this car.
Weaknesses of Niva Urban
- Transmission;
- Transfer case;
- Oil seals and cardan cross.
Now more….
Since the Lada 4×4 Urban is an urban variation of the classic NIVA, many problems for these cars are the same:
Front fenders.
This car does not have high corrosion resistance, and after a couple of years, quite serious corrosion may appear on the front fenders, near the headlights. In order to check the condition of the wings, you need to take a flashlight with you and properly inspect their inner surface. To be sure, you can touch the metal with your hand.
If fresh wheel arch liners were put on the car, then most likely they tried to close the pockets of rust in such a simple way.
Transmission.
One of the weakest points of this SUV. The gearbox is checked while the car is moving. If the speeds turn on with a creak and rattle or there are other unpleasant sounds, then this is probably the gearbox is excessively worn out due to untimely maintenance and this, in turn, will require expensive repairs.
Transfer case.
It is imperative to check how easily the differential lock is engaged. If during movement with the lock on, a strong vibration occurs or a rattle is heard, then the car needs urgent repair. But if a howl is heard while driving, then this is quite natural for these cars.
Seals and cross of the cardan shaft.
Do not forget that the Lada 4 × 4 Urban has an impressive off-road potential, so the seals and CV joints have not disappeared. Don't expect them to be perfectly clean. The main thing is that the seals are physically intact, without cracks and smudges. The cross of the cardan shaft must also be intact, without visible damage. All this can be checked by driving the car into the simplest garage pit.
It is also worth mentioning that you should avoid buying lifted cars or cars with power bumpers installed. Such design changes seriously reduce the resource of the car and leave no doubt that NIVA was used in severe off-road conditions.
The main disadvantages of LADA 4×4 Urban
- Weak sound insulation;
- Ergonomic miscalculations;
- In some cars, downshifting is difficult;
- Cheap interior plastic for a car of this price;
- Poor-quality plastic elements of the car;
- Small luggage space.
Conclusion.
As a practical domestic car with the quality of interior trim and ergonomics in Lada Urban, not everything is so good. But if the choice fell on this particular car, then in any case it is necessary, with the help of specialists and the necessary equipment, to diagnose all systems, components and assemblies for the absence of defects. If this is not possible, then at least it is necessary to pay attention visually and during a test run to the performance of all elements of the machine.
Overview of Lada Urban
P.S. Dear current and future owners of Niva Urban cars! Write in the comments about the weaknesses, diseases and shortcomings of your car, identified during operation. Thank in advance.
Weaknesses and main disadvantages of Lada 4 × 4 Urban was last modified: March 29th, 2019 by Administrator
The VAZ "Niva" has a chance to repeat the record of the VAZ "classics": if the "Lada" was produced for 42 years, then an SUV built on "classic" units, in order to surpass such a dubious achievement, needs to hold out on the assembly line for the next four years. Will the old lady survive? During those 16 months that Bo Andersson is in charge of the plant, the finish line of the Nivov career has been postponed three times already!
Recall that "in the pre-Andersson era" the VAZ-2121 SUV was given time until 2006. But since demand did not fall, in 2009 the car underwent a deep technical update, which made it possible to delay the inevitable retirement for at least a decade. And when Andersson was shown the current car, the new president, without any hesitation, said: the release must be extended until 2021! But - subject to mandatory modernization.
From this approach, engineers, accustomed to saving every penny and hardly knocking out even minimal improvements for the ancient structure, were frankly stunned, although the project for a radical renovation for the Swede was promptly prepared. It turned out according to the principle of "walk like a walk": new engine, steering and interior, floor mats, improved transmission and chassis...
The most important innovation was to be the appearance of another engine. Instead of the current 85-horsepower "Zhiguli" unit with a volume of 1.7 liters (which does not differ in elasticity due to the working range clamped between 3000 and 4500 rpm), it was planned to install a derated engine from Priora with a volume of 1.6 liters: with the same power, it would have an important characteristic for an SUV - "maximum torque at a minimum speed."
There were also plans - bend your fingers! - the introduction of a steering rack instead of a worm gear and an electric drive of the transfer case (this would allow removing a pair of “transmission” levers from the passenger compartment), a complete restructuring of the climate system, which would allow us to abandon the ancient “sliders” by switching to rotary knobs ...
But when the crisis broke out, the modernization project was recognized as economically unjustified. And it was decided: let the current Lada 4x4 be produced until 2017 (unless, of course, demand collapses), and only when the Niva-3 debuts will the old woman be sent to rest. Only the change of interior was recognized as justified (the new salon will be shown to the public in a year), the refinement of the "climate" and small "technical changes" like other wheel bearings and door locks. And nothing more.
However, the new engine may well appear under the hood of the “old Niva”! Known for its 1.8-liter engines for the Priora, the Togliatti company Super-Auto has prepared a project for finalizing the old engine: increasing the working volume to 1800 “cubes” (by installing a new crankshaft and increasing the piston stroke) made it possible to increase power to 93 hp and torque to 150 Nm.
Also, the “super-avtovtsy” realized another old dream of the VAZ workers - they got rid of the central differential lock levers and the downshift. The filling of the "razdatki" remained the same, but a pair of electric drives was added: the electric motor cocks the spring, which moves the fork, and when the teeth stand up as needed (this scheme is called "delayed start"), the specified mode is turned on - "lock", "lower" or both together . Conveniently!
Alain Dibuan, who is now responsible for the fate of the model, really liked the 1.8-liter Lada 4x4. But it is not clear that such a car will reach the conveyor - just before the May holidays, information appeared that the contract of the VAZ vice president for products and programs would soon expire ... And if the Frenchman leaves his post, the project may stall.
But what about the next generation of Niva? Its release was originally scheduled for 2017. However, a more realistic date is now called - 2019 (then the production of Lada 4x4 will also be stopped). According to our information, in order to speed up the development process, some VAZ workers suggested taking the current Shniva (nee Niva-2) as a basis, especially since the appearance of the second generation of the Russian-American SUV was supposed to release welding and stamping equipment ...
The offer was like this. Take the “Shnivy” power frame, which is “weighed” with other body panels in order to change the appearance, instead of the “classic” engine, use the new 1.8 (it is now being developed by AvtoVAZ), and the congenital misalignment of the gearbox and the “razdatki” fixed only on two supports is eternal source of terrible vibrations - eliminate by installing a subframe.
But Andersson believes that the car of the 1977 model needs to be finalized! With an eye on the current and future Shnivy. Which will greatly complicate development. That is why "Niva-3" at the current stage is just a couple of slow-moving layouts, on which proportions, layout and design are being worked out. So far, the Russians want the third-generation SUV to resemble the current Lada 4x4 in size, and at the same time be produced in both 3-door and 5-door versions.
With the new Chevrolet Niva, the situation is much clearer - the second-generation car is almost ready. By the way, VAZ sources claim that the Americans were given the rights only to the Niva brand, in Latin. While AvtoVAZ continues to be the owner of the trademark written in Cyrillic. But GM-AvtoVAZ claims that both spellings belong only to them.
The problem could be resolved radically. Renault-Nissan allocates money, and AvtoVAZ buys out GM's share, thanks to which Niva gets rid of the Chevrolet prefix forever (the shares of the GM-AvtoVAZ joint venture are divided in half: one half - from the Russian auto giant, the second - from the General Motors concern). But the Americans, despite the recent capitulation, refused to leave the joint venture! How they refused to allocate money for the development of the plant ...
Because of this, the creation of the second generation Chevrolet Niva stalled. No, contrary to the statements of the GM press service, the project is by no means frozen, the engineers are not fired, but it is impossible to bring the car to the assembly line without proper funding, which means that instead of full-fledged development, there is sluggish floundering. And the extension of the release of the existing Shnivy for an indefinite period.
But! Firstly, the enterprise is obliged to stop assembling the current Chevrolet Niva until the end of 2016, when the Vehicle Type Approval (OTTA) ends. Secondly, the SUV will have to ... significantly rise in price. Since the Americans violated the terms of the industrial assembly agreement with their sudden departure, the state is no longer obliged to compensate the recycling fee to the enterprise! And who needs an expensive car not the first freshness?
The Ministry of Industry and Trade unexpectedly decided to save the situation. This has not yet been announced, but the department of Denis Manturov is ready to make concessions: extend the OTTS until at least the end of 2017 and make an exception for the scrap collection. During this time, the governments - both Russian and regional - promise to attract borrowed funds and start producing Shnivy-2.
According to our information, Russian banks from the “Big Three”, which include Sberbank, VEB and VTB, are ready to provide a loan against state guarantees, so now the JV CEO Jeffrey Glover is working on a detailed action plan, the main details of which will be presented to the public in just a few days. So the new Chevrolet Niva will definitely appear. Just not for American, but for Russian - albeit credit - money.
Accordingly, the new production, designed to produce 120,000 bodies annually, and the new engine plant, where they will launch the production of 1.8-liter gasoline engines (135 hp and 170 Nm) under license from PSA Peugeot Citroen, will be completed and launched . (The project for the production of power units is being implemented with the money of the Togliatti Plant of Precision Parts and the Indian corporation Avtec).
In the meantime, the new Shnivy rolls test kilometers. The “winter” tests have already ended, the driving tests are in full swing. Suppliers are ready to start producing the necessary components. When will production cars appear? Everything will become clear after Glover's speech. If Russian banks promptly finance the project (which must first be approved by shareholders and the management of the joint venture), then the premiere of the Chevrolet Niva-2 will take place at the 2017 Moscow Motor Show.

Minor changes in appearance, however, significantly affected the impression that leaves the appearance of the car. If you look at the photo of LADA Niva Urban, you will notice that the look of the classic car has become more modern. This variation received a modified grille and plastic bumpers made in body color. Plastic is scratch-resistant, so any off-road will be conquered without mechanical damage. You can also recognize the new Lada Niva Urban 4x4 2019 by the absence of chrome parts, replaced by a strict black coating. The car stands out with its 16-inch alloy wheels.
Interior convenience and comfort are built into the base
The owner of the legendary car in the new variation can count on more:
- The comfort of being in the compact interior of LADA Niva Urban is provided by the basic option - a powerful climate system. Athermal glasses keep a pleasant cool in the car for a long time. Yes, and the use of new materials for upholstery.
- The slightly modified central tunnel received cup holders and a special handle with which power windows are controlled and heated exterior mirrors are electrically adjusted.
- Driving comfort has also been improved by extending the rear window cleaning area, which improves visibility for the driver.
New Niva Urban, which we will talk about today, has noticeably freshened up in appearance, which is confirmed by numerous photographs that have flooded the network. On the photo Niva Urban 2015 model year, the most striking attributes of a well-worn compact SUV are striking.
Firstly, the bumpers are now plastic and tightly attached to the body, it would seem such a trifle, but how it transforms the entire exterior. In place of the bumpers put a more interesting grille. The door frames are no longer shiny, but black, like the door handles. Thresholds are also painted black. There are new, large and comfortable mirrors painted in body color. All this gives a complete and harmonious image. new Lada Urban. See photos of the car below.

In fact, Niva Urban is a luxury version of the usual Lada 4x4. The cabin has air conditioning, fabric upholstery of a more decent look, large mirrors with heating and adjustment, alloy wheels, improved sound insulation, power windows. In technical terms, nothing has seriously changed yet, the same engine, transmission. Today the price of Niva Urban is 438,000 rubles.
Specifications of the new Niva Urban
Characteristics of Niva Urban regarding the engine and transmission remained the same, but the manufacturer announces an upgrade. An old, noisy (due to the chain drive) and voracious 8-valve VAZ-21214 gasoline engine with a power of 83 hp. they want to replace it with a more economical 1.6-liter engine with a timing belt and a lightweight connecting rod and piston group. New Niva Urban engine VAZ-11186 is capable of developing 87 hp. with the same 8-valve, but at the same time provide 143 Nm of torque, against 129 Nm with today's engine. In addition to improving dynamics, such a replacement will provide serious fuel savings.
As for the transmission, there are still three incomprehensible levers in the cabin, for urbanized citizens. According to preliminary information, only one lever will be left this year, this is the gearshift lever. The “razdatka” and “lower” levers will be removed, instead, the all-wheel drive will be switched on by means of an electric clutch, by simply pressing a button. Tests new version of Niva Urban transmission are already underway. The photo is attached below.
The electronic activation of the 4x4 all-wheel drive transmission will get rid of the hum and vibration of the transfer case in the Niva Urban cabin. Further, the main characteristics of a compact SUV that are relevant today. Of the significant changes in dimensions, a slight decrease in ground clearance and a change in the total length of the car can be noted. The length has decreased due to new, more compact bumpers.
Dimensions of the new Niva Urban, clearance
- Length - 3640 mm
- Width - 1690 mm
- Height - 1640 mm
- Wheelbase - 2200 mm
- Ground clearance - 200 mm
- Trunk volume - 265 liters (with the rear seat folded down - 585 liters.)
- Tire size - 175/80 R16 or 185/75 R16
- Engine displacement - 1690 cm3
- Power - 83 hp (61 kW) at a torque of 129 Nm
- Acceleration to 100 km / h - 17 seconds
- Maximum speed - 142 km / h
- Fuel consumption in mixed mode - 9.7 liters
- Gearbox - 5 tbsp. mechanical
- Transmission - 4x4
Recently, there have been intense rumors that the new Niva Urban can get a VAZ-21128 engine with a working volume of 1.8 liters and a power of 120 hp. This power unit is put on limited batches of the Lada Priora model in the Togliatti company Super-Auto. There are even experimental samples of the new NIVA with such a motor. However, how much the Niva will rise in price with such an engine is not clear.
