If you’ve ever wondered, “What litre is my car?”, you’re essentially asking about its engine size. Knowing your car’s engine capacity is more than just trivia—it’s crucial for fuel efficiency, performance, maintenance costs, car insurance, and even resale value. Whether you’re buying a used car, comparing vehicles, or planning maintenance, understanding engine size will help you make smarter decisions. In this guide, we’ll explain what engine litres mean, how they affect performance, and the easiest ways to check your car’s engine size using tools like Total Car Check.
What Does “Litre” Mean in a Car Engine?
The litre (L) in a car engine refers to engine displacement—the combined total volume of all the engine’s cylinders. It’s usually shown in litres (L) or cubic centimetres (cc). For example:
- 1.0–1.2 litre engine – Small and fuel-efficient, usually found in city cars and compact hatchbacks.
- 1.4–2.0 litre engine – Mid-range, common in family cars, saloons, and SUVs.
- 2.0–3.0 litre engine – More powerful, typically found in performance vehicles and larger estates.
- 3.0 litre+ engine – High-performance sports cars, luxury models, or heavy-duty SUVs.
Why it matters: Engine size directly impacts your car’s performance, fuel consumption, road tax, and emissions rating.
How Engine Size Affects Fuel, Insurance, and Driving Experience
When asking “what litre is my car?”, it’s important to know how that number influences daily running costs and performance.
1. Fuel Efficiency
- Smaller engines (1.0–1.4L) use less petrol or diesel, making them cheaper to run.
- Larger engines (2.0L+) burn more fuel but deliver stronger performance.
2. Performance
- Bigger engines generally provide better acceleration, higher top speeds, and stronger towing capacity.
- Turbocharged small engines can sometimes match mid-range engines for power while remaining more fuel-efficient.
3. Car Insurance Costs
- Insurance companies often factor in engine size when calculating premiums.
- Cars with larger engines tend to be placed in higher insurance groups, meaning higher costs.
4. Environmental Impact
- Larger engines usually produce higher CO₂ emissions, which can affect road tax, ULEZ (Ultra Low Emission Zone) compliance, and environmental charges.
How to Check Your Car’s Engine Size
Not sure how to find your engine litres? Here are three easy ways:
- Check Your V5C Logbook / Registration Certificate
Your V5C document lists engine size in litres or cubic centimetres (cc). - Look Under the Bonnet
Many vehicles have a manufacturer plate or sticker on the engine block or inside the door frame that shows engine size. - Use Total Car Check (Fastest & Easiest)
With Total Car Check, all you need is your registration number to instantly see:- Engine size in litres (L) and cubic centimetres (cc)
- Engine type (petrol, diesel, hybrid, or electric)
- MOT history and due dates
- Vehicle tax status
- Outstanding finance, write-off history, and other checks
This is especially useful when buying a second-hand car or verifying details before booking a service.
Why Knowing Your Engine Size Matters
- Maintenance & Repairs – Engine size determines the correct oil type, filters, spark plugs, and parts.
- Resale Value – Many buyers search specifically for cars with certain engine capacities (e.g., “best 1.6L cars for first-time drivers”).
- Fuel Planning – Helps calculate realistic miles per gallon (MPG) and running costs.
- Tax & Compliance – Certain low-emission zones, congestion charges, and road tax bands are based on engine capacity and emissions.
FAQ
Q1: How can I find out what litre my car is?
You can check your V5C logbook, look for an engine label under the bonnet, or use an online service like Total Car Check to instantly view your engine size.
Q2: Is engine size the same as engine power?
No. Engine size (litres) refers to displacement, while power is measured in horsepower (bhp) or kilowatts (kW). A smaller turbocharged engine can produce more power than a larger naturally aspirated one.
Q3: Does engine size affect car insurance?
Yes. Cars with larger engines often fall into higher insurance groups because they deliver more power, which can increase accident risk.
Q4: Which engine size is best for fuel economy?
Generally, smaller engines (1.0–1.4L) are most fuel-efficient, while larger engines offer better performance but use more fuel.
Q5: What’s the difference between CC and Litres in engines?
CC (cubic centimetres) and litres both measure engine displacement. For example, 1,598cc is roughly equal
Final Thoughts
If you’re asking yourself, “What litre is my car?”, the answer is only a few clicks away. By checking your V5C logbook, under the bonnet, or using Total Car Check, you can quickly find your car’s engine size, type, and specifications.
Understanding your car’s engine litres is more than technical knowledge—it’s about saving money, ensuring compliance, improving fuel efficiency, and protecting your vehicle’s value. Whether you’re planning a long trip, budgeting for insurance, or shopping for a used car, knowing your engine size gives you the confidence to make informed choices.
