What exactly is the difference between a niva urban and an ordinary niva. What exactly is the difference between a niva urban and an ordinary niva Weight of a niva urban
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, but to highlight a few problem areas at present, it is possible to know about which future owners need to know 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 costly repairs.
Transfer case.
It is imperative to check how easily the differential lock is engaged. If a strong vibration occurs or a rattle is heard while driving with the lock on, the car needs to urgent repair. But if a howl is heard while driving, then this is quite natural for these cars.
Oil seals and crosspiece 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 installed power bumpers. 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 weak points, illnesses 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 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 new motor and of 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 neck-to-neck drilling 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.
cylinder block and crankshaft 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. At the inlet camshaft fix the master disk, 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. Rusks, guides, valve stem seals- 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 stand, he demonstrated a high fuel economy. 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 controller, now on the shaft exhaust valves. And on this, I am sure, the development of this engine will not end.
While many Niva fans are waiting for the release of a completely modified model, AvtoVAZ decided to restyle the old version, which will become a little more modern, but retain common features in appearance, as well as modest interior equipment. Niva Urban 2018 will still remain an unpretentious workhorse, which was the old model, and will be better able to overcome all sorts of off-road conditions.
The car will hardly change in appearance. Still, it will be a square device, which does not have a relief at all, however, it will still be possible to find some new elements here.
New model now it does not have a smooth hood - it was supplemented by a small in-depth strip. The angle of inclination of the windshield has slightly decreased, due to which it is now located almost perpendicular to the hood.
The photo clearly shows that the grill covering the radiator has been updated. Now it is a strongly protruding plastic insert with a large number of cutouts. Along its edges are placed exactly the same as before, round headlights with a simple halogen filling. Fog lights, as well as turning lights, have moved to the top.
From below there is now nothing but a massive body kit made of metal, which is also complemented by a plastic insert and protection for the subframe.
To find any changes on the side of the car, you need to be well versed in cars. There are very few obvious changes - new mirrors, wheels and door handles. Everything else is the materials from which many elements are made. Now these are better metal alloys that increase safety.
New body changed the most in the back. The shape of the door has changed a little luggage compartment, a strip of stop lights was added, dimensions received a new shape. The body kit was also strengthened, because of which it became even more beautiful.
Salon
Unfortunately, what really required changes did not receive them. We are talking about the interior, in which there is nothing attractive at all. The new Niva Urban 4x4 2018 model year does not have any elements that increase comfort, has not even acquired the simplest multimedia, and still gets off with cheap plastic and fabric, which are not very pleasant to the touch.
The most expensive part on the dashboard is the simplest audio system. It is located at the very bottom of the panel. Above it are several rows of deflectors, stove settings and other useful options.
The tunnel is best made in the car. It houses the settings and controls for the gearbox, chassis, parking brake and even two cup holders. Another hole is located at the very beginning, and it is quite roomy.
In addition to its main functions, the steering wheel can also control the lighting of the road using two buttons on the spokes. The steering wheel itself looks unpleasant and feels about the same in the hands. Under a wide rectangular visor, pointer instruments are placed showing the speed at which the car is moving, as well as the speed developed by the motor. on-board computer not provided.
The chairs are the most uncomfortable here. Fabric upholstery, hard filling, lack of lateral support and generally no safety features - all this is about the seats in the Niva. But in a rich configuration, you can find heating, which is quite unexpected. If you can still somehow sit in front, then only children can normally accommodate in the back, since there is practically no legroom between the rows. The sofa itself is not wide and short, although it is designed to seat three passengers.
The trunk has also grown a little in the car, but it is still not enough to travel normally when there are more than two people in the car.
Specifications
Like the old Niva, Lada Urban 2018 does not have a wide range of engines, the characteristics of which will be at least somewhat similar to what can be found from competitors. Only one gasoline is put here power unit, the volume of which is 1.7 liters, and the power is only 83 forces. Together with all-wheel drive and a five-speed manual transmission, the car can accelerate to a hundred in an unthinkable 17 seconds, which is a very, very long time. At the same time, the consumption of such a system is enormous - up to 13 liters in the city and 7 on the highway. The advantages of the machine can be considered a transfer case and locks of all differentials that are only available in the chassis. As the test drive showed, the car is completely unsuitable for everyday trips both around the city and on the highway, but few people can argue with it off-road.
Options and prices
The minimum set of options for Niva Urban 2018 is represented by a stove, cigarette lighter, manual adjustments and power windows, fabric interior, anti-lock braking system, a full range of off-road systems, power steering and other simple features. The price for this version of the car will be 450 thousand.
To get the most charged modification, you will have to pay 80 thousand. This will also include an air conditioning system, heating for the first row seats, rear parking sensors, electric lifts for the front row windows, slightly better interior trim and one airbag.
Release date in Russia
According to representatives of AvtoVAZ, the start of sales in Russia will begin in January 2018. A few weeks later, the car will go to the markets of neighboring countries.
Competitors
Now the market of both our country and others is being actively filled with compact SUVs. This is due to the fact that the fashion for them has reappeared. In addition to the Niva, we are in great demand, and. These models can be purchased at a relatively low cost, but you will not achieve a high level of comfort and safety from them. Devices such as, and are somewhat better equipped. They cost much more, but these machines are at a higher level of performance.
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. To know new Lada Niva Urban 4x4 2019 will also be possible due to the absence of chrome parts, replaced by a strict black coating. The car stands out with its 16-inch alloy rims.
Interior convenience and comfort are built into the base
Owner legendary car in the new variation can count on more:
- The comfort of being in a compact salon LADA Niva Urban is provided with a 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 is also improved by extending the cleaning area rear window, which improved visibility for the driver.
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 transfer box(this would allow to remove a couple 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. Justified recognized only a change of interior ( new salon will be shown to the public in a year), 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-auto" realized another old dream of the VAZ - they got rid of the levers for blocking the central differential and switching on 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 . Comfortable!
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 “razdatka” 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 new Chevrolet Niva the situation is much clearer - the second generation machine 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 under state guarantees, so now CEO JV Jeffrey Glover is working on a detailed plan of action, 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, a new production facility, designed to produce 120 thousand bodies annually, and a new engine plant, where they will launch the production of 1.8-liter gasoline engines(135 hp and 170 Nm) licensed by 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.
