VAZ 2114 is a Russian hatchback that replaced the discontinued nine. The changes affected not only the external parts of the body (new headlights, hood, bumpers, moldings, radiator grille), but also the interior.

Sports style VAZ 2114

The modern appearance of the VAZ 2114 car is given by moldings along all sides, a spoiler with a brake light and door sills. External changes to the VAZ 2114 justify themselves, giving the car excellent aerodynamic qualities, as well as road stability even at high speeds. Bumpers, moldings and other attached parts are designed in the same color scheme as the body, or are made in black, which gives the VAZ 2114 model a resemblance to foreign cars and gives buyers the opportunity to choose the design of the car’s exterior.

For its appearance, the car was loved by people involved in tuning. And I fell in love due to the fact that at low cost the VAZ 2114 can be made individual, standing out from the general traffic flow.

How much does the VAZ-2101 weigh: characteristics

The first Zhiguli of this model has a bare weight of 955 kilograms, of which 114 was the weight of the engine. This is exactly the answer to the question: how much does the VAZ-2101 weigh?

A car's gearbox is:

• four-speed;
• five-speed.

Weighs 26.2 kg together with clutch, shift lever and clutch release fork. This data must be taken into account when replacing a particular part.

The flywheel, which has a native weight of 6.873 kg in the hands of its owners, often reduces the weight with the help of tuning to 3.6 kg. This promotes maneuverability and increases the speed of the car on the road.

The “classic” is sold in used condition, since its production has been completed, but, of course, according to documents containing the owner’s data and technical parameters of the car. Assembled parts of the VAZ-2101 car are sold everywhere.

VAZ has retained its shape and the love of the public from all segments of the population to this day. Volzhsky Automobile is not going to stop there, producing more and more modifications of the Zhiguli. If we consider how much each component of a VAZ car weighs, it will become clear that the total weight of each of them is approximately the same.

It is worth noting that of all Soviet cars, only the VAZ-2101 was supplied to Japan. The popularity of the VAZ is not least associated with the name of Kimi Raikkonen, who achieved his first victories with this car. The father of the famous racer considered this car the most reliable.

If we look at the weight of the VAZ, we can say that throughout its fifty-year history, the weight of cars of this brand has fluctuated from a ton to a ton of three hundred kilograms, but, in fact, has not undergone large and significant changes.

Technical data VAZ 2114

As can be seen from the table with the technical characteristics of the VAZ 2114, the difference with models of its class lies only in the dimensions of the body. The 1.6-liter eight-valve engine is installed on many AvtoVAZ models, so you shouldn’t expect any special characteristics. The drive is front-wheel drive, the gearbox is like everyone else’s, so to speak, standard. The differences between hatchbacks and sedans lie in the volume of the trunk, which increases when the rear seat backs are folded. There is no point in comparing the performance of the VAZ 2114 with the classics - aerodynamics due to smoother body lines makes the car easier to drive. But otherwise, the VAZ 2114 is an ordinary Russian car that wins the hearts of car enthusiasts thanks to its appearance.

Body dimensions: checking car geometry

Repair work to restore the VAZ 2101 body should begin with checking its geometric dimensions.
The geometry of the body can be disrupted as a result of various mechanical influences, loss of rigidity and elasticity of rusty structural elements. To ensure that the vehicle's geometry corresponds to its original parameters as a result of restoration work, check the control points specified in the vehicle's operating instructions. How many mm of taper is allowed will be answered by the manufacturer, who determined the unevenness of the gaps to be 1.5 mm.

If the tolerances for the front elements of relatively fixed structures are more than 2 mm, then restoration of the geometry of the frame is required, which is carried out in auto repair shops using special equipment - a slipway. If there are no serious discrepancies in the geometric dimensions, measured and certified, you can proceed to the next step - welding work.

VAZ 2101 body weight

Almost all modern sedan-type cars are equipped with a monocoque body, the VAZ 2101 is no exception in this case.
What does a monocoque body mean, you ask? This means that the steel body box is not only a comfortable container for passengers, the driver and their luggage, but also “carries” (and in itself) all the elements, components and assemblies of the car. The body of the VAZ 2101 perceives not only the static loads of the elements attached to it, it also resists their influence during movement (in dynamics). This property of the car frame is called torsional rigidity, which on a “penny” is about 7300 Nm/deg.

This indicator of the strength and rigidity of the VAZ 2101 body is greatly influenced by the condition of its bottom, sills and roof, which are interconnected by the front panel, pillars of door and window openings, and the transverse panel of the luggage compartment. You can verify for yourself the integrity of the geometry, and therefore the general condition of your car, by taking the dimensions of the VAZ 2101 body with your own hands and checking them with the data contained in the car repair instructions.

What follows from the above? And the fact that body fatigue directly affects not only the control points of attachment of components and assemblies, which are shown in the VAZ 2101 body diagram outlined above, it also manifests itself in the “purity” of the geometry of its side and front openings. The dynamic distribution of loads throughout the body occurs as follows: from the suspension elements at the front, vibration and shocks pass to the cross member and then to the sub-engine frame, and then to the area of ​​the mudguards and the front shield, which are already load-bearing elements of the body. At the rear, approximately the same picture occurs, only in a shorter form, that is, without the participation of mounting the power unit, directly from the suspension to the car body.

As you understand, with this type of body and the operation of its suspension, an important role in the stability and safety of the car is played by what the car frame itself is made of. It is clear that the more we strengthen the weak points of the body, the stiffer and more stable it will be, but this is the whole point of the trick question: how much does the body of the VAZ 2101 weigh? By strengthening the car frame, we increase its mass, thereby increasing the load on its structural parts. Vicious circle? Not at all, which is why smart people in institutes teach such a science as strength of materials, after studying which design engineers rationally selected the thickness of materials, their aspect ratio and cross-section. Ultimately, all these factors helped to obtain a high-strength frame of the VAZ 2101.

Body dimensions of the VAZ 2101 in the cabin, thickness of materials

To save weight and reduce costs, non-load-bearing parts (luggage compartment lids and engine compartment) are made of thinner metal. The thickness of the steel sheets from which the most important elements for the strength of the body are composed is about one millimeter, which is no less (one might even say more) than that of other modern cars of a similar class.

The front and rear “tail” of the “penny” are welded to the body, which allowed them to be included on equal terms in the supporting structure of the car, which also contributed to reducing its weight, which is 955 kilograms.

But this is its total weight; the following layout will help us find out how much the body of the VAZ 2101 weighs:

• 140 kilograms - the weight of the power unit with attachments;
• 26 kilograms – gearbox;
• 10 kilograms – cardan shaft;
• 52 kilograms – rear axle;
• 7 kilograms – radiator;
• 280 kilograms is the actual weight of the VAZ 2101 body.

It's not a particularly impressive number. And if we multiply it by all the cars produced over all the years of production (from 1970 to 1988) in the amount of 4.85 million? Agree, every gram saved plays a significant role here!

But it's not that simple. The durability of the body does not lie in the thickness of the metal sheet from which it is made, it depends on how well the anti-corrosion protection was carried out at the manufacturer (in our case, by the owner himself).

As a rule, after welding operations, before the paint booth, the VAZ 2101 body was subjected to phosphatization, during which its entire surface was exposed to a chemically resistant phosphate film. In addition to this, the result was secured with a layer of primer applied using electrophoresis, which allowed the primer layer to create an even coating in the most difficult to reach areas. The bottom of the car, in turn, was covered with a layer of special durable mastic, which reliably protected it from the effects of an aggressive external environment.

All of the above in the coupe contributed to the fact that the VAZ 2101 became popular not only in its time, but confidently “holds the brand” of a reliable hard worker to this day.

By the way, the “penny” was one of the first cars of the famous Formula 1 pilot Kimi Raikkonen, whose father was extremely attached to it for its unpretentiousness and reliability.

Vehicle weight

Nowadays, few people are interested in such a characteristic of a car as its weight, and if they are interested, then in the last place. It is much more important for the average person to know his appetite, speed, cost and other indicators. Although, by and large, the weight of the car actually affects all its other indicators.

For example, the heavier the car, the more powerful the engine must be installed in it so that it can reach the required speed and accelerate to 100 km in a matter of seconds. The same can be said about fuel consumption - the heavier the vehicle, the more gasoline or diesel fuel it will need to move.

A car's directional stability and handling are also directly related to its weight. The peak of popularity of large, heavy cars abroad occurred in the 50-60s of the last century. Then the auto industry produced truly gigantic cars. For example, the Cadillac Eldorado modification 8.2 weighed almost 3 tons. Agree that for such a weight, an appropriate makeweight is needed.

How much do the car frame and body parts weigh?

The VAZ 2101 has a monocoque body on which all the components and elements of the car are located. This means that the body absorbs all static and dynamic loads of the components and assemblies attached to it. With this type of body, the frame material is very important.

How much the body of a “penny” weighs depends on what it is made of. The fact is that strengthening weak points and increasing the mass of the frame lead to increased load on structural parts and elements.

To reduce the weight and cost of the car, non-load-bearing elements are made of thinner metal. The most important structures for strength have a thickness of about 1 mm, that is, at the level of modern vehicles of similar class.

You can find out how much the body weight of a “penny” is by adding up the mass of its elements:

• power unit with attachments, weight – 140 kg;
• rear axle, weight – 52 kg;
• gearbox, weight – 26 kg;
• cardan shaft, weight – 10 kg;
• radiator, weight – 7 kg;
• bare body of VAZ 2101 – 280 kg.
