The question is how much does it weigh? VAZ 2105, often arises among car enthusiasts planning repairs, tuning, or simply interested in the technical side of the legendary “classics”. The weight of a car is not just a number on the passport, but a critically important parameter that affects acceleration dynamics, fuel consumption and braking efficiency. For owners upgrading a powertrain or replacing suspension components, an accurate understanding of weight characteristics becomes the foundation for sound engineering solutions.
The weight of the Soviet sedan varied depending on the year of manufacture, engine type and configuration. The standard curb weight of the base model was about 1060 kilograms, but actual figures may vary. The difference in weight between an “empty” body and a fully equipped car can reach several tens of kilograms, which significantly affects car behavior on the road, especially in winter or when making sharp turns.
In this article we will look in detail at what the mass of the “five” depends on, how it changed during production and why this data is important for the modern owner. Understanding the weight distribution across the axles will help you set up correctly carburetor, choose optimal shock absorbers and avoid overloading bridges when transporting goods.
Body weight and main characteristics of the model
Body VAZ 2105 made of sheet steel and is a load-bearing three-volume structure. It is the body that makes up the lion's share of the total weight of the car. The weight of the bare body (without engine, attachments and interior) is approximately 650-700 kilograms. This value is important to know for those involved in major restoration or welding work, since metal intensity directly affects the cost of restoration.
The body design of the “five” underwent changes throughout the entire production period. Early models had thicker metal and reinforced safety features, making them heavier than their modern counterparts from the late '90s. On the other hand, corrosion, which is the scourge of classic Lada cars, can significantly reduce the weight of the car, turning repairs into a struggle to preserve every kilogram of useful metal.
It is important to consider that the weight of the body is distributed unevenly. Approximately 55-58% of the weight falls on the front axle, where the engine and transmission are located. This creates additional stress on the front shock absorbers and suspension arms, requiring them to be checked regularly and replaced when play occurs.
⚠️ Attention: When purchasing a replacement body, remember that the weight of the painted and primed product may differ from factory specifications by 5-10% upward due to the use of a thicker layer of anti-corrosion and paint.
Accurate knowledge of the weight of the body is also necessary to calculate the load capacity. If you plan to use your vehicle to transport heavy objects, subtracting the body weight from the gross vehicle weight rating will give you an idea of how much cargo can be safely loaded into the trunk and interior.
Differences in weight of different modifications of the VAZ 2105
Over the many years of production, the “five” was produced with various engines, which directly affected its final weight. The basic modification with a 1.2 liter engine (VAZ-2101) was the lightest. More powerful versions with 1.3 and 1.5 liter engines (VAZ-2105, VAZ-21011) had an increased mass of the power unit, which shifted the center of gravity and changed the overall picture.
The modification stands out VAZ 21053, equipped with a 1.5 liter engine. This version is considered one of the most dynamic and popular among the people. The difference in weight between the 1.2 and 1.5 liter engines is small (about 10-15 kg), but in combination with the reinforced transmission and other elements it is noticeable. For tuning and sports, it is the weight of the engine that plays a key role in calculating the power-to-weight ratio.
- 🚗 VAZ 2105 (1.2 l): The lightest version, ideal for the city due to lower fuel consumption and sharper response to the gas pedal.
- 🚙 VAZ 21051 (1.3 l): An intermediate option, which is less common, but offers a balance between dynamics and efficiency.
- 🏎️ VAZ 21053 (1.5 l): The heaviest and most powerful civilian version, in demand among fans of fast driving.
In addition to the engine, the weight was influenced by the equipment. The presence of an electric fan instead of a mechanical impeller, a more massive generator or additional soundproofing material added kilograms. In the later years of production, manufacturers often skimped on materials, which led to a decrease in weight, but also to deterioration soundproofing and vibration protection.
When carrying out technical work, such as replacing the engine with a more powerful one, always take into account the change in weight distribution. Installing a heavy engine without strengthening the front suspension can lead to premature failure of the levers and silent blocks.
Specifications table and weight data
For clarity, let’s compare the main parameters of various modifications. The data may vary slightly depending on the year of production and the specific example, but it gives a clear idea of the weight categories.
| Modification | Engine | Power (hp) | Curb weight (kg) | Gross weight (kg) |
|---|---|---|---|---|
| VAZ 2105 | 1.2 l (VAZ-2101) | 64 | 955 | 1355 |
| VAZ 21051 | 1.3 l (VAZ-21011) | 69 | 965 | 1365 |
| VAZ 21053 | 1.5 l (VAZ-2103/2106) | 72-77 | 1010 | 1410 |
| VAZ 2105 (export) | 1.3 l (carburetor) | 69 | 980 | 1380 |
As you can see from the table, the difference in curb weight between the lightest and heaviest version is about 55 kilograms. This is equivalent to the weight of an adult passenger or full luggage, which significantly affects the dynamics. Gross weight indicates the maximum permissible weight of a vehicle with passengers and cargo, exceeding which is strictly not recommended.
⚠️ Attention: Exceeding the gross vehicle weight leads to overheating of the brakes, reduced steering efficiency and accelerated tire wear, which is especially dangerous on slippery roads.
When calculating the load capacity, always leave a small margin. Factory data is based on ideal conditions, and actual wear on suspension parts reduces permissible loads. If you often carry heavy loads, it makes sense to install reinforced leaf springs or springs.
Effect of weight on dynamics and fuel consumption
The weight of a car directly correlates with its appetite. The heavier the car, the more energy the engine requires to accelerate it and maintain speed. For the “five” with its relatively weak engine, every extra kilogram counts. Losing weight is one of the most effective ways to increase dynamics without interfering with the engine.
During city driving, where you constantly have to brake and accelerate, the difference in fuel consumption between a loaded and empty car can reach 1-2 liters per 100 kilometers. This is due to the fact that when braking, the kinetic energy of a heavy machine is uselessly dissipated in the form of heat from the brake pads, and during acceleration it is necessary to burn additional fuel.
- ⛽ City cycle: Weight has the greatest effect on consumption in traffic jams and with frequent starts from traffic lights.
- 🛣️ Route mode: At constant high speeds the influence of mass is less, but it affects consumption when overtaking and climbing.
- 📉 Savings: Removing excess cargo from the trunk (old tires, tools) is an easy way to reduce consumption.
To save fuel, regularly check the tire pressure - underinflated wheels increase rolling resistance, which is equivalent to increasing the vehicle's weight by several tens of kilograms.
Weight also affects braking distance. A heavy vehicle is more difficult to stop, especially if the braking system is not in perfect condition. For owners of heavy modifications VAZ 21053 You should pay special attention to the condition of the brake discs and pads, perhaps considering the installation of more efficient analogues from more modern models.
Weight loss: tuning and preparation for competitions
In motorsport and amateur tuning, weight reduction (downsizing) is a priority. This is especially true for “classics”, since stock engines have limited power reserves. The first step is usually to remove everything unnecessary from the interior: the rear sofa, sound insulation, spare wheel (if regulations allow) and heavy standard acoustics.
More advanced methods include replacing metal hoods and trunk lids with plastic or carbon fiber alternatives. Replacing glass with thinner ones (polycarbonate) also gives a noticeable effect, although it reduces comfort and safety. However, it is worth remembering that excessive lightening can upset the balance of the car, making it too light on the front axle and prone to skidding.
Approximate weight that can be saved with proper lightweighting:- Removing the rear sofa: -20 kg
- Removal of sound insulation: -15 kg
- Glass replacement: -10 kg
- Plastic hood: -5 kg
Total: up to 50 kg weight reduction
It is important to approach the issue of weight loss wisely. Removing safety features such as body reinforcements or bumpers is not acceptable for a vehicle driven on public roads. The goal of tuning is to improve performance while maintaining handling and reliability.
⚠️ Attention: When removing heavy interior elements (for example, a rear sofa), the operation of the fuel sensor may be disrupted and the behavior of the suspension may change, which will require additional adjustment of the shock absorbers.
For those who are not ready for radical measures, simply moving the heavy battery into the trunk (although this increases the overall weight due to the wires) can improve weight distribution, but in the case of the “five”, where the front axle is already overloaded, it is better to focus on lightening the front part of the car.
Load capacity and real world operation
The registered carrying capacity of the VAZ 2105 is about 400 kilograms (including the weight of the driver and passengers). This means that the trunk and interior can safely accommodate approximately 4 adults and light cargo. However, actual operation often involves overload, especially during the summer season or when transporting building materials.
Overloading the rear axle is a common mistake of owners. A trunk that is packed to capacity causes the “nose” of the car to lift up, impairing the traction of the front wheels with the road. This makes the steering feel wobbly and dangerous, especially at high speeds or when braking. In addition, springs suffer, which may burst or lose elasticity.
☑️ Checking readiness for cargo transportation
If you regularly have to carry heavy loads, you should consider installing spacers under the springs or replacing them with reinforced options. Also, do not forget that the gross vehicle weight should not exceed the values specified in technical passport, otherwise you risk getting a fine or becoming the culprit of an accident due to a technical malfunction.
Compliance with the specified load capacity extends the life of the suspension and transmission, and also guarantees driving safety in emergency situations.
Frequently asked questions (FAQ)
How much exactly does the VAZ 2105 body weigh without an engine?
The weight of the bare body (frame) is approximately 650-700 kg. If you take into account the attached elements (doors, trunk lid, hood), but without the engine and interior, the weight will be about 800 kg. The exact figure depends on the year of manufacture and the degree of metal corrosion.
Does replacing a carburetor affect the weight of the car?
Virtually no effect. The difference in weight between the standard Ozone or Solex carburetor and their tuning versions is calculated in grams, which does not in any way affect the overall weight of the car or its dynamics.
Is it possible to increase the carrying capacity of the “five”?
It is legally impossible to increase the passport carrying capacity. Technically, it is possible to strengthen the suspension (springs, springs, shock absorbers), but this does not change the strength of the body and the effectiveness of the braking system, so operation with overload remains dangerous.
Why does the weight of my car differ from the data in the table?
Weight may vary due to accumulated dirt, installed additional equipment (alarm, music, HBO), as well as due to corrosion (loss of metal weight) or body repairs performed using a thicker layer of putty.
