Every car has an engine, but do you know how big yours is? Knowing your car’s engine size helps you understand how much power it has, how much fuel it uses, and how much it costs to run.
You can check car engine size easily using your car documents or an online car spec check tool. In this guide, we will show you how to check your car engine size, what it means, and why it matters.
Key Takeaways
- Engine size shows how much air and fuel your car’s engine can burn, which affects how powerful it is and how much fuel it uses.
- You can easily check your car’s engine size by checking the V5C logbook or using an online car engine size check tool.
- Smaller engines save more fuel and are cheaper to run, while bigger engines give more power, faster speed, and stronger performance on the road.
What Is the Meaning of Engine Size?
Engine size means how much air and fuel the engine’s cylinders can hold. It’s also called engine capacity. The size is measured in litres (L) or cubic centimetres (cc).
For instance, a 1.0-litre engine means the engine’s cylinders hold one litre of air and fuel, while a 2.0-litre engine holds twice as much.
A bigger engine can make more power because it burns more fuel. But it also uses more petrol or diesel and gives lower fuel mileage.
Small engines (like 1.0L or 1.2L) are great for city driving and saving fuel. Big engines (like 3.0L or 4.0L) give more speed and power for larger cars or sports cars.
Engine Size vs Engine Power
Engine size is not the same as power. Power is shown as horsepower (HP) or brake horsepower (BHP). For example, two 2.0L engines may have different horsepower because of design or turbo features. When you check car engine size, you’ll learn about capacity. When you check the power, you’ll learn how strong the engine is.
How Do I Find My Car’s Engine Size?
There are several simple ways to check your car engine size. You can find it using your car documents, online tools, or even by looking under the bonnet.
Check the V5C Logbook
The V5C logbook (vehicle registration certificate) shows your car’s engine capacity (cc) on the front page. An engine size: 1598 cc” means your engine is 1.6 litres.
Look Under the Bonnet
Some cars have the engine size printed on a label or metal plate inside the engine bay. You might see something like “1.6L” or “1998cc” on the engine cover or near the oil cap.
Check the Owner’s Manual
Your car’s handbook also lists the engine size, type, and code. This is helpful if you can’t find your logbook or want to double-check details.
Use the DVLA Service
You can visit the DVLA online service and type in your registration number, which will show your car’s make, model, colour, and engine size.
Use a Car Engine Size Check Tool
The fastest and easiest way is to run an instant car engine size check. You just need to enter your car’s registration number or VIN (vehicle identification number). You will find key information about the engine specifications like engine size, Fuel type, power (HP), make and model.
Car Engine Sizes Explained
Engines come in many sizes and types. Let’s look at what different sizes mean and what they are good for.
Small Engines (Under 1.5L)
Small engines are common in city cars like the Ford Fiesta or Toyota Aygo. They usually range from 1.0L to 1.4L and are great for short drives, daily commutes, and light fuel use. These engines are easy to maintain and cheaper to insure.
Even though small, they can still be powerful. Many modern small engines use turbochargers to boost performance without using much fuel. They’re perfect for new drivers and people who want low running costs.
Large Engines (2.0L and Above)
Large engines are found in SUVs, sports cars, and luxury vehicles. They provide strong power, smooth performance, and faster acceleration, making them ideal for long drives or towing heavy loads. A typical example is a 3.0L V6 or a 4.0L V8 in a Mercedes AMG.
While they deliver great performance, large engines use more fuel and produce more emissions. They also cost more to insure and tax. These engines are best for drivers who value power over fuel savings.
Turbocharged Engines
Turbocharged engines are designed to give more power without increasing engine size. A turbo pushes extra air into the engine, helping it burn more fuel and make more power. This means a 1.4L turbo engine can perform like a 2.0L engine.
They are great for drivers who want strong performance with good fuel economy. Turbo engines are now very common in modern cars, offering the best mix of speed, efficiency, and fun driving experience.
Smart Car Engine Size
Smart cars are built for city life, so they have very small engines, usually between 0.9L and 1.0L. These engines are small but efficient, helping drivers save money on fuel and parking space.
Even with a small engine, Smart cars perform well in towns and cities. Their lightweight body makes them easy to park and drive in traffic. They may not be fast, but they’re practical and eco-friendly for short trips.
F1 Car Engine Size
Formula 1 cars use small but powerful engines, only 1.6 litres! But thanks to turbocharging and hybrid systems, they produce over 1,000 horsepower. These engines are built for extreme speed and top performance.
Even though the size is small, F1 engines show how advanced technology can make a little engine very strong. They’re not like normal car engines and they’re designed purely for racing and can spin up to 15,000 revolutions per minute.
Club Car Golf Cart Engine Size
Golf carts, like Club Car models, use very small engines, around 400cc (0.4L). They can be petrol-powered or electric, and are made for smooth, quiet rides over short distances.
These engines are simple and reliable. While they don’t reach high speeds, they offer enough power to move around golf courses, resorts, or neighbourhoods. They’re built for comfort and efficiency, not for fast driving or heavy loads.
First Car Engine Size
If you’re buying your first car, go for an engine between 1.0L and 1.4L. It’s powerful enough for daily use but still cheap to insure and maintain.
Small engines also help new drivers build confidence on the road. They’re easy to handle, fuel-efficient, and perfect for short commutes or city travel. Once you gain experience, you can explore larger engine options.
Average Car Engine Size
In the UK, most cars have engines between 1.5L and 2.0L. This size gives a good balance between power, comfort, and fuel efficiency, making it ideal for everyday driving.
Cars in this range can handle both city roads and motorways easily. They’re neither too weak nor too powerful, just right for most families and drivers who want performance without high running costs.
Does Engine Size Matter?
Engine size matters because it affects how your car performs, how much fuel it uses, and overall running costs.
Fuel Economy
Smaller engines use less fuel because they burn a smaller amount of air and petrol. Bigger engines burn more fuel to make more power. If you drive mostly in towns, a smaller engine saves money on fuel.
Performance
Larger engines usually give faster acceleration and smoother power, which is great for long drives or hills. Smaller engines can still perform well, especially turbo ones, but may feel slower when carrying heavy loads or driving on motorways.
Tax and Insurance
Vehicles with bigger engines often have higher road tax and insurance costs. Smaller engines are cheaper to insure and better for drivers who want to save money on running costs each year.
Resale Value
Cars with balanced engine sizes, like 1.5L or 2.0L, often keep their value longer. Very large engines can lose value faster due to higher fuel use, while tiny engines might limit the car’s appeal to some buyers.
Driving Needs
Your driving habits matter more than size alone. A small engine is great for short city drives, while a bigger one fits long trips, towing, or carrying passengers. Pick the engine that matches how and where you drive.
Modern Technology
With turbocharging and hybrid systems, even small engines can make strong power today. Modern 1.0L or 1.5L turbo engines perform like older 2.0L engines while still saving fuel, making engine size less important than efficiency and design.
