What Engine Is In My Car? The Complete Guide

Knowing what engine is in your car is essential for everything from routine servicing to future upgrades or even when selling the vehicle. Whether you’re a casual driver, an automotive enthusiast, or someone looking to buy a used car, understanding your engine's details can help you make informed decisions. This comprehensive guide will walk you through the various ways to identify your car’s engine, decode engine codes, and explain how different engine types affect your car’s performance.

How To Identify Your Car Engine

Before diving into engine specifics, let’s look at different methods to help you identify what engine is in your car.

Vehicle Identification Number (VIN)

The Vehicle Identification Number (VIN) is your car’s unique identifier, providing a wealth of information about your vehicle, including engine details. Here’s how to use the VIN to determine what engine is in your car:

Step-by-Step Guide to Decoding Your VIN:

  1. Locate your VIN: The VIN can typically be found on the dashboard, visible through the windscreen, or on the inside of the driver’s side door frame.

  2. Find the 8th digit: The eighth digit in the VIN refers to the engine code. While this won’t give you the engine size outright, it’s a unique code that can be looked up to get more detailed information.

  3. Use a VIN decoder: Enter your VIN into an online VIN decoder or the vehicle manufacturer’s database to uncover your engine’s specifics.

VIN decoders are an easy way to access a comprehensive profile of your car, including engine specifications and other critical details.

Under The Bonnet

If you're still wondering what engine is in your car, one of the simplest methods is to look directly under the bonnet.

Where to Find the Engine Number:

  • The engine number is often stamped on the engine block, typically located near the cylinder head or the engine’s timing belt cover.

  • It can also appear on a metal plate or a sticker attached to the engine.

Tips for Reading the Engine Plate or Sticker:

  • You may need a torch if the engine number is hard to see.

  • The engine number typically consists of both letters and numbers, which you can use to identify the engine model and type.

Owner's Manual

Your car’s owner’s manual is a straightforward resource for identifying your engine. If you’re looking for detailed information about the engine size or type, the manual will have it.

  • Check the specifications section: The manual will usually list the engine’s details early on or in a dedicated section about vehicle performance.

  • Look for the engine specs: You’ll likely find information about the engine displacement (e.g., 2.0L) and configuration (inline-4, V6, etc.).

Online Tools & Resources

Several reliable online tools can assist in determining what motor is in your car. These tools typically use either the VIN or engine number to give you detailed information.

Recommended Online Tools:

  1. VIN Decoder Websites: UK-friendly websites such as CheckCarDetails, or HPI Check allow you to input the VIN to find out engine details.

  2. Manufacturer’s Websites: Car manufacturers often offer online databases where you can search your vehicle’s engine details by entering the VIN.

  3. Car Enthusiast Forums: For older or less common vehicles, car enthusiast forums can be a treasure trove of information.

Understanding Engine Codes & What They Mean

Engine codes offer a way to identify and understand your vehicle’s engine specifications. If you’ve been asking yourself, “what motor is in my car?” engine codes hold the key.

What Are Engine Codes?

Engine codes are a series of numbers and letters used by manufacturers to define an engine’s characteristics. These codes can tell you a lot about the engine’s size, configuration, fuel type, and sometimes performance features.

How To Interpret Engine Codes

  • Displacement: Engine codes often include a number indicating the engine displacement in litres (e.g., 1.8L).

  • Configuration: Letters like "V" or "I" show the cylinder layout (e.g., V6 for a V-shaped six-cylinder engine, or I4 for an inline four-cylinder engine).

  • Fuel Type: Some engine codes specify whether the engine uses petrol, diesel, or another fuel type.

  • Additional Features: Codes sometimes reveal other details like turbocharging, direct injection, or whether the engine is designed for high performance.

For example, the engine code Z16XER on a Vauxhall Astra indicates:

  • Z: Represents a low-emission petrol engine.

  • 16: Denotes a 1.6-litre engine.

  • XER: Refers to specific features like variable valve timing.

What Different Engine Types Mean For Your Vehicle

After determining what engine is in your car, it’s helpful to understand how different engine types impact performance, fuel efficiency, and maintenance.

Common Engine Types:

  1. Inline Engines (I4, I6): These engines are compact, simple, and typically offer good fuel efficiency, commonly found in hatchbacks and smaller vehicles.

  2. V-Type Engines (V6, V8): Known for producing more power, V engines are commonly used in larger cars, SUVs, and performance vehicles.

  3. Flat or Boxer Engines: Found in vehicles like the Subaru Impreza, these engines have a low centre of gravity, improving handling and balance.

Common Questions About Car Engines

What is the difference between engine size and engine type?

  • Engine size refers to the displacement, measured in litres (e.g., 2.0L), while engine type refers to the arrangement of cylinders (e.g., V6, inline-4).

How can I tell if my engine has been replaced?

The best way is to compare the VIN and the engine number. If they don’t match the records from when the car was new, the engine may have been swapped.

What should I consider if I need to replace my engine?

Make sure the replacement engine is compatible with your vehicle. It’s essential to match engine size, type, and ensure it works with the car’s electrical and fuel systems.
