Have you bought a used car, but the engine power is unclear or missing in the documents? Or want to check if the real "horsepower" corresponds to (hp) the data that the seller claims? VIN code - your main assistant in this situation. This unique 17-digit identifier not only reveals the history of the car, but also stores technical characteristics, including engine power.

In this article we will look at 5 working ways, how to find out engine horsepower by VIN code - from free online services to decoding through government databases. You will learn what nuances are important to consider when checking European, American and Russian auto, as well as how to avoid mistakes when interpreting data. No fluff - just specific instructions with examples and warnings about pitfalls.

What is a VIN code and where to find it in a car

VIN (Vehicle Identification Number) - this is the “passport” of the car, which is assigned at the factory and remains unchanged throughout its “life”. It consists of 17 characters (numbers and Latin letters, except I, O, Q), which encode information about the manufacturer, model, year of manufacture, engine and even equipment.

Where to look for VIN?

  • 🔍 Under the windshield (bottom right, visible from outside) - the most common place.
  • 🚗 On the sign in the doorway (driver's side, on the pillar).
  • 🔧 Under the hood - on the cylinder block or frame (more often in trucks).
  • 📄 In documents: PTS (line “VIN”), STS (column “Identification number”), insurance policy.

Important: on some machines (for example, Mercedes-Benz or BMW) VIN may be duplicated in several places - check all options to avoid errors during verification.

Method 1: Free online VIN checking services

The fastest way is to use specialized sites that decipher VIN and provide technical data, including power in hp or kW. Here are the top 5 proven services:

Service Region Data Accuracy Need registration?
VinFormer Russia/CIS High (traffic police base) No
VinDecoderz World brands Medium (depending on brand) No
VINCheck.Info Europe/Asia High (manufacturers' data) Yes (free 3 requests)
NHTSA (USA) USA/Canada Official data No
Kombat Auto Ukraine/Europe Good (Ministry of Internal Affairs base) No

How to use:

  1. Enter your VIN into the search field on the website.
  2. Wait for decryption (usually 5-30 seconds).
  3. Find a section Engine Power, Engine power or kW/HP.
  4. If the power is indicated in kW, multiply by 1.36 for transfer to hp (for example, 100 kW × 1.36 = 136 hp).
💡

If the service gives the error “VIN not found”, try another site - the databases are updated with a delay. Also check if you entered the characters correctly (a common mistake is to confuse 0 and O, 1 and I).

Method 2: Checking through government databases (State Traffic Police, EAISTO)

In Russia, engine power can be clarified through official sources - this is especially true if you buy a car second-hand and want to avoid problems with taxes or registration.

Methods:

  1. State Services Portal:
    • Login to gosuslugi.ru.
    • Go to section Transport and driving → Vehicle check.
    • Enter the VIN or license plate number - the system will show data from the traffic police database, including power in hp.
  • EAISTO (Unified Automated Information System for Technical Inspection):
    • Request an extract via eaisto.ru (registration required).
    • The statement will contain an item Engine power (hp).
    ⚠️ Attention: If the data on the State Services and the PTS differs, this may mean that the car has been re-equipped (chip tuning, engine replacement). In this case, the power must be clarified through examination or dealership.

    Method 3: Deciphering the VIN manually (for experienced)

    If you don’t trust online services or want to figure it out yourself, you can decrypt the VIN manually. Engine power is usually encoded in 8–9 characters (for most brands), but the algorithm depends on the manufacturer.

    Decryption examples:

    • 🚘 Toyota: 8th character - engine code (for example, 1NZ-FE → 109 hp).
    • 🚘 Volkswagen/Audi: 6–7 characters - motor model index (for example, CBFA → 105 hp).
    • 🚘 Ford: 8th character - engine series (for example, Zetec → power is specified according to the tables).

    To decrypt you will need:

    • 📖 Manufacturer tables (search for “VIN decoder [car make] PDF”).
    • 🔧 Spare parts catalogs (for example, ETKA for VW, EPC for Mercedes).
    ⚠️ Attention: Manual decoding requires experience - an error in one character can lead to the wrong power. For example, engines BMW N43 and N46 they are similar in appearance, but have different power (from 122 to 170 hp).
    How to check the authenticity of a VIN before decoding

    1. Make sure the length is exactly 17 characters.

    2. Check the checksum (9th character) using the algorithm ISO 3779.

    3. Check the first 3 characters (WMI) with the manufacturer database (for example, XTA — Lada, WDB — Mercedes).

    Method 4: Checking by PTS and STS (documentary method)

    If you have it in your hands PTS (vehicle passport) or STS (registration certificate), the engine power is indicated there explicitly. Where exactly:

    • 📄 B PTS: section “Engine”, item Engine power, hp (kW) (line 10).
    • 📄 B STS: graph 12. Engine power, hp.

    But there are nuances here:

    • ⚠️ If the car refurbished (for example, a turbocharger is installed), the data in the documents may be out of date.
    • ⚠️ B European cars power is often indicated in kW - don’t forget to convert to hp. (×1.36).
    • ⚠️ B American cars may be specified SAE net (real power) and SAE gross (overestimated, excluding losses). The difference is up to 20%!

    Example: In PTS Ford Mustang 2018 power indicated 310 kW. We translate: 310 × 1.36 = 421.6 hp (round up to 422 hp).

    💡

    If in the PTS the power is indicated in kW, and in the STS - in hp, and the numbers do not add up, this is a reason to request an extract from the traffic police or check the car for official website.

    Method 5: Contact a dealer or examination (for complex cases)

    If all of the above methods give conflicting results (for example, VIN services show 150 hp, and in PTS - 130 hp), there are two reliable options left:

    1. Official dealer:
      • Provide VIN and title details.
      • The dealer will make a request to the manufacturer's database and issue an official response (usually free of charge for customers).

    📌 Example: For Volkswagen this can be done via official website (section “Owners”).

  • Independent examination:
    • Cost: from 2,000 to 5,000 rubles.
    • The expert will take readings from the engine control unit (ECU) or perform a dyno test.

      • 📌 Where to order: Centers Bosch Service, ATL or auto repair centers with a diagnostic license.

    ⚠️ Attention: If the power in the documents is underestimated (for example, to reduce transport tax), this is a violation Art. 12.1 Code of Administrative Offenses of the Russian Federation (“Managing a vehicle with data inconsistency”). The fine is up to 800 rubles, but if the violation is repeated, the license plates may be removed.

    Common mistakes and how to avoid them

    When checking power by VIN, many people encounter typical problems. Here's how to solve them:

    Error Reason Solution
    VIN not found in the database New model or rare brand Try another service or contact your dealer
    Power in kW and hp. doesn't converge Rounding or translation error Use the exact odds of 1.35962
    The service and PTS data are different Chip tuning or error in documents Order an examination or check the history via CarVertical
    VIN starts with 000 or 999 Fake or broken VIN Check the car for theft in the traffic police database

    Advice: If you buy a car second-hand, always check the VIN on the body with what is indicated on the title. Mismatch is a sign interrupted number (often happens with stolen cars).

    Is it possible to find out the power from the VIN if the car is older than 2000?

    Yes, but accuracy varies by brand. For Russian cars (for example, VAZ 2109) the data may not be available in online databases - in this case, only PTS or examination will help. For foreign cars (for example, Toyota Corolla E110) information is usually available, but the power may be indicated in SAE gross (overpriced).

    Why do services show different power for one VIN?

    This happens due to:

    • Different data sources (for example, VinDecoderz takes information from factory catalogs, and VinFormer - from the traffic police database).
    • Errors in the databases (for example, after restyling the model, the power may have changed, but not all services have time to update).
    • Chip tuning (if the previous owner increased the power programmatically, this will not be reflected in the VIN).

    🔹 What to do: Take data from PTS or official dealer.

    How to check the power of an electric car by VIN?

    For electric cars (for example, Tesla, Nissan Leaf) power is indicated in kW and refers to the electric motor. The VIN encodes the battery model and motor type, but it is better to clarify the exact power:

    • Via Tesla official website (for Tesla).
    • In the machine's mobile application (for example, My BMW App for BMW i3).
    • On a sticker under the hood or on the charging port.
    Is it possible to find out from the VIN whether there has been chip tuning?

    No, the VIN does not store information about program changes. But indirect signs:

    • Power in PTS lower than the on-board computer shows.
    • In the service history (via Carfax or Autocheck) there are records about the firmware ECU.
    • On the forums of owners of your model there are topics about typical “firmware” (for example, for Skoda Octavia 1.8 TSI often increase power to 220 hp).

    🔹 For an accurate check you need diagnostic scanner (for example, Launch X431), which reads the original firmware.

    What to do if the power in the PTS is too high?

    It could be:

    • An error when completing documents (for example, a typo).
    • Deliberate overestimation for “status” (found in tuned cars).
    • The consequence of replacing the engine with a more powerful one (for example, instead of 1.6 MPI installed 1.8 TSI).

    📌 Solution:

    1. Check VIN via traffic police database.
    2. If the data does not match, contact the MREO for clarification.
    3. If you suspect fraud (for example, the engine is clearly weaker than declared), order an examination.
