How Car Brands Structure Vehicle Specs by VIN: A Guide for Buyers

Buying a car? Whether new or used, you should know exactly what you’re getting. The Vehicle Identification Number (VIN) helps you check a car’s details. But did you know that car brands structure VINs differently? This guide explains how automakers use VINs to store vehicle details. You’ll also learn how to lookup vehicle specs and options by VIN to check a car’s features before you buy.

What is a VIN?

A VIN is a unique 17-character code for every car. It acts like a fingerprint, showing important details such as:

✅ Manufacturer
✅ Model and trim
✅ Engine and transmission
✅ Production year and plant

The National Highway Traffic Safety Administration (NHTSA) requires every car to have a VIN. Though the format follows a standard, each automaker structures VIN details differently.

How a VIN Is Structured

Every VIN has three main parts:

Though all cars follow this format, different brands use VIN sections in unique ways.

How Car Brands Structure VINs Differently

Ford & General Motors (GM): Powertrain Details

American automakers like Ford and GM include many powertrain details in their VINs.

🚗 Ford VIN Example:

• The 8th character identifies the engine. (e.g., “H” = 5.0L V8, “F” = 3.5L EcoBoost V6)
• The 10th character represents the model year (e.g., “M” = 2021).

🚗 GM VIN Example:

• The 4th-8th characters show the model and trim level.
• The 8th character specifies the engine (e.g., “Y” = 6.2L V8 in a Chevrolet Silverado).

🔎 Why it matters: This helps buyers verify engine type and drivetrain before purchase.

Toyota & Honda: Market-Specific Features

Japanese brands like Toyota and Honda use VINs to define trims and market-specific features.

🚗 Toyota VIN Example:

• The 4th-8th characters show the model and trim.
• The 10th character still follows the standard model year coding.

🚗 Honda VIN Example:

• The 6th character identifies transmission type (manual vs. automatic).

🔎 Why it matters: Buyers can confirm if the vehicle has the right trim and factory-installed features.

BMW, Mercedes-Benz & Audi: Safety & Emission Data

Luxury European brands focus on safety, emissions, and high-detail specs in their VINs.

🚗 BMW VIN Example:

• The 4th-8th characters show body style, engine size, and performance options.
• The 11th character indicates the assembly plant.

🚗 Mercedes-Benz VIN Example:

• The 4th-6th characters identify the model range (e.g., “WDD” for C-Class).
• The 9th character is a check digit for validation.

🚗 Audi VIN Example:

• The 7th character shows drivetrain type (front-wheel drive vs. quattro AWD).
• The 8th character identifies engine type.

🔎 Why it matters: Buyers can confirm engine size, performance trims, and safety details.
