Why is it important to know the class of the car and where this information will be useful
Car class is not just a marketing ploy by manufacturers. Depend on him tax rates, cost OSAGO, customs duties upon import, as well as market price when selling. For example, owners of class cars D (business) they pay 15–30% more for insurance than for a car of similar power class C (medium). And during customs clearance Luxury sedans (class F) increased coefficients are applied.
But the problem is that in Russia there is no unified register of car classes - they are determined according to the European UNECE classification, which often diverges from the marketing designations of manufacturers. Yes, Volkswagen Polo in the cabin it is positioned as a “compact sedan”, but by European standards it is a class B (small), and Audi A4 - not “premium”, but just class C (average). Our instructions will help you sort out this confusion.
Method 1: Determining the class by VIN code
The most accurate method is checking through VIN code (vehicle identification number). It contains encrypted data about the model, year of manufacture and basic configuration, which directly affect the classification. For example, the first 3 characters of the VIN (WMI) indicate the manufacturer and segment car:
- 🔍 1–3 characters (WMI): Factory coding. For example,
WVW— Volkswagen (classes A–D),WDB— Mercedes-Benz (grades E–F). - 📌 4–8 characters (VDS): model description. The body type (sedan, hatchback) and overall parameters, critical for the class.
- 🔢 9 character: check digit (does not affect class).
- 📅 10 character: year of manufacture. Important for history classes (eg. Mercedes-Benz S-Class until 2000 belonged to the class E, not F).
To decrypt VIN, use official services:
- 🌍 VIN decoder “Behind the wheel” (free of charge, with the Rosavtotrans database).
- 🔗 VinFreeCheck (international base, shows UNECE class).
⚠️ Attention: Some decoders (for example, on dealer websites) may issue marketing class instead of real. Check the data with the UNECE table (see section 4).
If the VIN is indicated in the decoding results Body Type: Sedan and Length: 4500–4700 mm, this is the 90% probability of the class C (average).
Method 2: Car class in PTS and STS
B vehicle passport (PTS) and registration certificate (CTC) the car class is indicated in the column "Vehicle type" or "Category". However, there is a catch: Russian documents use own classification, which does not always coincide with the European one. For example:
| Designation in PTS/STS | UNECE class compliant | Examples of models |
|---|---|---|
Passenger car (category B) |
A, B, C, D | Lada Granta (B), Toyota Camry (D) |
Passenger all-terrain vehicle |
J (SUVs) | Toyota Land Cruiser 200, Mercedes-Benz G-Class |
Cargo-passenger |
M1 (minibuses) | Volkswagen Multivan, Ford Tourneo |
To convert a Russian category to a European class, use catalog Auto.ru — in the filters, select the brand and model, and then look at the section "Class" in the characteristics.
⚠️ Attention: In the new type STS (from 2023), the class can be indicated as "Passenger M1". This not UNECE class, but a category according to the technical regulations of the Customs Union! For an accurate determination, use VIN or dimensions.
Method 3: Classification by engine size and displacement
If there are no documents at hand, the class can be determined by physical parameters car. The UNECE European Commission uses the following criteria:
- 📏 Body length:
- A (extra small): up to 3.6 m (Smart Fortwo, Toyota IQ).
- B (small): 3.6–4.2 m (Hyundai Solaris, Kia Rio).
- C (medium): 4.2–4.7 m (Volkswagen Golf, Skoda Octavia).
- D (business): 4.7–4.9 m (Audi A6, BMW 5 Series).
- 🔋 Engine capacity:
- Classes A–B: up to 1.6 l.
- Classes C–D: 1.6–3.0 l.
- Classes E–F: from 3.0 l (exception - hybrids and electric cars).
- 🚗 Body type: hatchbacks and station wagons are usually classified a class lower than sedans of the same length (e.g. Volkswagen Polo Sedan - class B, and Polo Hatchback - class A).
To measure the length, use a tape measure from the front bumper to the rear (not including the license plate). The engine capacity is indicated in the PTS (column "Working volume") or on the nameplate under the hood.
How to measure the length of a car without a tape measure?
Stand next to the car and measure in steps: 1 step ≈ 0.7 m. For example, if there are 6 steps (4.2 m) from bumper to bumper, this is a class C.
Official UNECE Class Table (2026)
The UN Economic Commission for Europe divides passenger cars into 6 main classes (A–F) and 3 specialized (S, M, J). Below is a current table with examples of models and key parameters:
| Class | Title | Length, m | Engine capacity, l | Examples of models |
|---|---|---|---|---|
| A | Extra small | up to 3.6 | up to 1.0 | Smart Fortwo, Renault Twizy |
| B | Small | 3,6–4,2 | 1,0–1,6 | Lada Granta, Hyundai Solaris, Kia Rio |
| C | Lower middle | 4,2–4,5 | 1,4–2,0 | Volkswagen Golf, Toyota Corolla, Skoda Octavia |
| D | Medium | 4,5–4,7 | 1,8–3,0 | Audi A4, BMW 3 Series, Volvo S60 |
| E | Business | 4,7–4,9 | 2,5–4,0 | Audi A6, Mercedes-Benz E-Class, Lexus GS |
| F | Lux/Premium | from 4.9 | from 3.0 | Mercedes-Benz S-Class, BMW 7 Series, Porsche Panamera |
| J | SUV/SUV | from 4.2 | from 2.0 | Toyota RAV4 (compact), BMW X5 (full size) |
Please note: electric cars (for example, Tesla Model 3) are often classified as a higher class due to their high cost, despite their modest dimensions. A sports coupes (for example, Porsche 911) may have a class S, which is not included in the main classification.
Class E (business) - the most “blurred”: this includes Audi A6 (4.8 m), and Volvo S90 (5.0 m). The main criterion is price and brand positioning.
Common mistakes when defining a class
Even experienced car owners often confuse classes due to marketing gimmicks manufacturers. Let's look at the most common misconceptions:
- 🚘 "Crossover = SUV": In fact, Toyota RAV4 or Nissan Qashqai belong to the class J (SUV), but only if they have permanent all-wheel drive and ground clearance >200 mm. "Fair" crossovers of the type Renault Arkana - this is class C or D.
- 💎 "Premium = class F": Audi A4 (class C) and BMW 3 Series (class D) are positioned as premium, but in terms of dimensions they do not reach Luxury.
- 🔄 “Restyling changes class”: Updated Skoda Octavia 2023 stayed in class C, despite the increased wheelbase. Class depends on base platform, and not from cosmetic changes.
Another trap - Chinese brands. For example, Geely Coolray in size (4.5 m) belongs to the class C, but in showrooms it is presented as a “premium crossover” (which corresponds to the class D). Always check the data against the UNECE table.
☑️ Checking the car class
How does the class of a car affect the cost of ownership?
Not only do they depend on the class taxes and insurance, but also maintenance costs. For example:
- 💰 Transport tax:
- Classes A–B: 12–25 rub./hp. (in Moscow).
- Classes C–D: 35–50 rub./hp.
- Classes E–F: 150–300 rub./hp. (for cars more expensive than 5 million rubles).
- 🛡️ OSAGO: Class coefficient F can increase the cost of the policy by 40% compared to the class B.
- 🔧 Repair and spare parts: Spare parts for Mercedes-Benz S-Class (class F) 3–5 times more expensive than for Hyundai Solaris (class B).
Example: Owner BMW 5 Series (class D, 249 hp) in Moscow pays RUB 12,450 tax per year, and the owner Lada Vesta (class B, 106 hp) - total RUB 1,272. The difference is almost 10 times!
⚠️ Attention: When importing a car from abroad, the class affects customs duty. For example, for cars of the class F the rate can reach 48% of the cost, and for the class B - only 25%.
FAQ: Frequently asked questions about car classes
Can the same car belong to different classes in different countries?
Yes. For example, Volkswagen Passat in Europe belongs to the class D, and in the USA - to class Mid-size (analogue C), since there are different size standards. In Russia they use the European classification.
How to determine the class of an electric vehicle?
Electric cars are classified according to the same rules, but adjusted for the price segment. For example, Tesla Model 3 (4.7 m) formally falls into the class D, but due to its high cost it is often classified as E (business).
Does the class affect the possibility of installing gas equipment (LPG)?
No, the class does not limit the installation of gas equipment. However, for cars of the class F (for example, Mercedes-Maybach) may be required individual approval with the traffic police due to the design features.
Is it possible to challenge the class of a car specified in the PTS?
Technically yes, but only through the courts. To do this you need to provide examination, confirming the discrepancy between the dimensions or parameters of the engine. In practice, such claims are rarely granted.
What is the class of minibuses? Volkswagen Multivan?
Minibuses belong to the class M1 (according to European classification) or "Cargo-passenger" in PTS. They are not included in the main classes A–F, but for tax purposes they can be equated to the class D or E.
