The car described below is an excellent model of the Soviet and Russian automobile industry. Its stability and practicality exceeded all the designers' expectations. The car can include good dynamics, maneuverability and solidity.
Auto VAZ 21099 under the name Sputnik/Samara is a four-door sedan of the Volzhsky Automobile Plant and is considered the culmination of the new generation Samara line.
Initially, from the moment of manufacture, in excellent years, configurations were produced with carburetor and, at the same time, injection engines, the volume of which was 1.3 liters (210993) and 1.5 liters (21099).
Technical characteristics of the VAZ 21099 brand, engine and dimensions
- length – 4 m 20.5 cm;
- width – 1 m 65 cm;
- height – 1 m 40.2 cm;
- wheelbase – 2 m 46 cm;
- ground clearance – 16.5 cm;
The model has a gasoline engine and a five-speed manual transmission. Another brand with code name (i), economical one and a half liters. engine and directed fuel injection (injector), which meets international standards for the toxicity of the exhaust gas supply structure.
VAZ 2109 body: introduction
ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"
Inside, the car body practically does not cause any complaints from car owners, despite its small, compact dimensions. However, there is enough space for a trip of five people of average build. The low-mounted dashboard is quite easy to operate; if necessary, you can build in modern electronic components, but this will require you to spend a significant amount of money.
There is a slight drawback in terms of the material construction of the interior, which is made of plastic. This is a significant drawback, since such a building periodically rattles and needs technical modernization to strengthen it. However, this is quite easy to do and you don’t have to spend a lot of money.
Car exterior/interior
The entire appearance of the car was a rarity for a person from the USSR. The car's handling and driving characteristics are solid and stable, harmoniously combined with the sedan body class. This body type is designed to carry 5 people.
VAZ 21099, its tank volume is 43 liters. The car is very respectable, multi-purpose (the rear seat, although not in parts, still folds, ensuring the transportation of long items). Quite good Russian upholstery.
The front-wheel drive arrangement creates excellent stability of the car against skidding approaching from the side. The layout on the front axle, when compared with the rear-wheel drive layout, makes it possible to more fully utilize the length of the car and reduce its weight, creating a more comfortable interior and driving position together with passengers. The positive volume increases without increasing its size.
The instrument panel equipment consists of an elegant combination of all devices and illuminated toggle switches that provide electrical guidance. window lifters along with fixing all doors. Infrastructure board. control informs the driver about the vital activity of all modules of the car. Tilt steering wheel is used in 1 set with updated panel.
The new product will provide a more comfortable seating for people along with the driver; they are equipped with seats, and precise adjustment of belt fasteners for protection at a specific height. The installation of fog lights improves the properties of car lighting in any bad weather.
How much horsepower can a VAZ 21099 have? The throughput (power) of the motors ranges from 54 to 140 “horses”.
Engine types
The first VAZ 21099 were equipped with a 1.3 liter carburetor engine. However, a lot of shortcomings, the main one being bending valves when the timing belt breaks, led to the replacement of this unit with a 1.5-liter one. With it, the VAZ 21099 carburetor’s technical parameters have noticeably improved, and malfunctions began to occur less frequently. The power unit allowed the car to accelerate to 100 km in 13.5 seconds with one passenger and in 15 seconds if its weight was close to the maximum.
The car's power is 70 hp. With. Fuel consumption is about 6 liters. The engine is single-row, the cylinders are combined into a common block, which increases rigidity and reduces size and weight. If the belt breaks, the valves on it do not bend. In 1997, the first car was released whose engine had distributed injection. This power unit turned out to be so successful that it still underlies all engines at the Volga plant.
Let's look at how the technical parameters of the VAZ 21099 injector changed after modernizing the engine. The engine has a displacement of 1500 cc and an 8-valve design. Of course, throughout the world this has not been something advanced for a long time, but do not forget that in Russia this was the first experience with an injection engine. The designers of the plant managed to create a unit that could be installed on the car without additional alteration of the VAZ body.
At the same time, the technical characteristics of the VAZ injector have remained virtually unchanged, the weight of the car and ground clearance remain the same. It is worth noting that on some models the ground clearance has nevertheless become slightly less due to the use of a neutralizer. In the car 21099 injector, the power specifications have increased. Now it is 81 liters. With. At the same time, it was possible to achieve fuel savings of about 10-15 percent.
According to owner reviews, injection makes starting the engine much easier in cold weather. At the same time, in their opinion, the car has lost its maintainability. In injection engines, a mixture of gasoline vapor and air is forced into the cylinders. This process is controlled by a special device - an electronic control unit. The designers of the plant did not invent it, but took a ready-made one. Initially, a block from GM was used.
However, in 1999, preference was given to Bosch ECUs. In addition, the domestic device “January” was used on the car. All ECUs provide the VAZ 21099 injector with technical parameters of approximately the same level and they are used not only on cars of the Samara family. If an injector is installed, the technical characteristics of the car engine are as close as possible to European environmental safety standards.
Intelligent features of Lada/VAZ 21099
This brand was initially distinguished from other modifications of the Samara family by the front part of the frame with elongated wings, without a plastic “beak” in front and a more elongated hood, a modern radiator grille.
It is worth mentioning that a variation with continuous all-wheel drive was produced (Lada Victory), but since sales were low, production was completed. As for the model with an eight-valve turbo engine (Lada Sport), it was manufactured only by personal order.
The injection unit of the VAZ 21099 car consumes 6.6 liters when driving on the road. a hundred kilometers away. In urban conditions, consumption is approximately 8.2 liters. In mixed mode about 7.8 liters. The highest speed is 161 km/h. Acceleration from zero to one hundred is about 14 seconds.
Car body overview
The 99th was produced with a sedan body, which eliminated one of the shortcomings characteristic of the VAZ 2109, the rear window being covered with dirt. In general, it is very ascetic, which was typical for all domestic cars of that time. However, it was the sedan that allowed the designers to achieve a greater possible load on the body as a whole. And the question arises, how much does the car weigh at the moment? However, the weight of the car has remained virtually unchanged compared to its predecessor - the weight is 950 kg.
The overall dimensions also remained the same. The exception is the length, which has increased by 200 mm due to the rear overhang. The body design remained virtually unchanged throughout the 15 years of production, and for the VAZ 21099 injector, the technical parameters also remained the same. This explains its great popularity among car tuning enthusiasts. Like all previous models of this family, the car's interior initially had a so-called low panel.
The instrument cluster on the early 99s had a more modest configuration. Subsequently, the car was equipped with a panel, the overall dimensions of which not only made it more capacious in appearance, but also made it possible to place the speakers of the acoustic system in it. At the same time, the creaking in the car has become much more, almost all car enthusiasts note this.
The car's ground clearance is 15 cm. This is quite enough for a comfortable ride on domestic roads. Of course, this is less than crossovers and especially SUVs, but the 99th also weighs much less. The vehicle's ground clearance can be increased slightly by using larger diameter discs. However, you should not abuse this - the car's handling deteriorates.
The VAZ 21099 has a spacious trunk, and the dimensions of the body allow it to transport cargo of impressive weight. But in order to fit everything into the luggage compartment, you first have to raise them to a decent height.
How much can a VAZ 21099 weigh?
The total weight of the vehicle during operation is 1 ton 340 kg. The front suspension is independent with shock absorbers, coil springs, lower trailing arms with braces and longitudinal stability adjusters (McFerson). The rear suspension is on transverse correlation arms, with cylinder springs and hydraulic shock absorbers.
The front brake configuration is disc, the rear brakes are drum, with automatic clearance adjustment. Drive – hydraulic, 2-circuit, diagonal, with a vacuum booster and brake booster stabilizer. The “handbrake” is for the brake devices of the rear chassis, the drive is a cable drive.
As a result, an improved modernization of Lada of the eighth and ninth models is presented for you. With all the attendant improvements and an extended rear end. In general, the car is still used by most car enthusiasts as the most modernized brand from the entire VAZ line.
Tuning
This power unit allows you to increase power to 90-95 horsepower without loss of engine life. Engine tuning could be done by replacing the carburetor with a direct injection system, as well as by installing new lightweight flywheels and crankshafts. The VAZ 21099 engine with an injector produced about 90 horsepower.
There are also options for tuning the VAZ 21099 engine, which involve installing a turbine and supercharger on the power unit. It should be said that the installation of turbines made it possible to obtain a significant increase in power, but the service life of such an engine is significantly reduced. As a result, car owners had to carry out complex overhauls every 70-90 thousand kilometers.
How is recovery carried out?
As a rule, restoration of original forms is carried out these days in car repair shops. It uses special equipment, often electronic, a slipway and other useful tools to bring the car to its original condition.
Note. A special platform is called a slipway. This design implies a rigid machine with strong, perfectly geometric shapes. It is on the slipway that the vehicle is rigidly attached to the basic, fundamental points. The metal of spaced apart, deformed elements is also drawn out on the slipway to the required, original dimensions.
The operation of fine-tuning the original geometry of the body and its parts is considered very delicate. It definitely requires individual skill and increased accuracy. Without the necessary equipment, such as a slipway machine, it is almost impossible to complete it.
On the other hand, many craftsmen have adapted themselves in garage conditions to bring skewed body elements to the required dimensions. True, this is done with errors, but they imply a slight deviation from the original indicators.
Most often, in the current conditions, the car’s suspension has begun to fail. Such deformation occurs, clearly, due to bad roads. And its displacement is very difficult to determine. After the car falls into a hole or receives a strong impact, it is highly recommended to immediately check the condition of the car for wheel alignment.

Repair
Repair of the power unit is carried out with your own hands. As practice shows, most car enthusiasts carry out this process in their garage. Elements such as the thermostat, water pump, spark plugs and high-voltage wires can be changed without problems. As for the injectors, to clean them you will need a special stand, which is available at car services.
To reduce fuel consumption, you can flash the engine control unit. This is what motorists do. This operation can only be performed independently, but it is recommended to contact professionals who understand the process and also carry out additional adjustments.
Carrying out a major overhaul will require some design knowledge and engine repair skills. So, to grind the plane of the block and head, you will need a surface grinding machine. Also, for boring cylinders, a boring and honing stand is required. All other operations are performed by hand.
Service
Engine maintenance, in this case, does not depend on its volume and power, since the carburetor and injector did not differ much in design features, except for the injection system. So, let's look at the procedure for carrying out maintenance of the power unit 21099.
Since the engines stopped being produced in 2011, the technical diagram will be given for a power unit that has undergone a major overhaul.
Maintenance - 1. Carried out after 1000 km. According to the recommendation, in this service it is worth changing the oil filter and power unit oil.
Maintenance - 2. Performed at 10,000 km. Here, not only the lubricating elements and the fuel filter are replaced.
Maintenance - 3. After 20,000 km, it becomes necessary to adjust the valves, replace all existing filters, and also diagnose the engine for leaks. It is also recommended to measure the compression and adjust the valves. Don't forget that you need to change the oil.
TO - 4. In this maintenance, the elements of the gas distribution mechanism, water pump, and clutch are checked. Also, in addition to the standard procedure for changing the oil and filter, the valve cover gasket is also changed. This maintenance is done at 30 thousand km.

What is body geometry?
ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"
Body geometry is a specific system in which all parts and elements of the body are located exactly the same, according to the geometric pattern specified at the factory by engineers. Think about how much work they had to do to draw the design of the future car, because the slightest discrepancy in size or shape would lead to a defect.
It is easy to understand a simple truth: every part of the car must have a certain shape. No matter how trivial it may sound, but, for example, if the contact marks of the car’s wheels with the road surface were not rectangular, then when driving the vehicle would deviate along the course, which of course is already bad.
Same for other details. If their shape is disturbed, they become distorted, unnecessary forces arise, which require additional energy to overcome. As a result, using the same wheels as an example, tires wear out faster, fuel consumption increases, and handling deteriorates, which inevitably leads to emergency situations and a decrease in safety.
Modified body geometry is always bad, especially when weather conditions worsen or in emergency situations, when it is necessary, for example, to brake sharply or make a maneuver. It is clear that a deformed body in these cases will be worse than a bomb planted under the hood.
