What Does A Car Engine ‘Size’ Actually Mean?
Understanding engine size involves delving into the core mechanics of an engine. Primarily, the size of an engine refers to the total capacity of its pistons to push through a mix of air and fuel across all cylinders. In technical terms, this is known as the engine’s displacement, which is commonly measured in cubic centimetres or cc. For example, if you consider a two-cylinder engine with a 1,000cc capacity, it means the engine has the capacity to displace one litre of air and fuel combined, with each cylinder contributing 500cc. This results in what is commonly referred to as a 1.0-litre engine.
Engine size doesn’t necessarily correlate to the exact displacement measurement. Often, it’s rounded to the closest tenth of a litre for simplicity. To illustrate, a power unit with a 1,020cc capacity would still be classified as a 1.0-litre engine, whereas a 1,160cc unit would be categorised as a 1.2-litre engine. This rounding off practice is widely adopted within the car industry and plays a crucial role in categorising and comparing different vehicle models.
The engine size isn’t just a numeric value; it has significant implications for the vehicle’s performance too. In general, a larger engine implies the ability to push through more fuel and air, resulting in more power output. However, this isn’t the only factor influencing a car’s performance. Other components such as turbochargers can also affect power generation, demonstrating that while engine size is important, it is part of a broader complex of elements that define a vehicle’s performance capabilities.
1.0-1.2 Litre Car Engines
A 1.0-1.2 litre car engines refer to the engine displacement or size of the combustion chambers within the engine. The term “1.0-litre” signifies that the total volume of all the cylinders in the engine is approximately 1,000 cubic centimetres (cc) or 1 litre.
1.0-litre car engines are commonly found in compact and subcompact vehicles. These engines are typically designed with three or four cylinders, and their small size allows for improved fuel efficiency and reduced emissions. They are often used in city cars or economy-focused models, where low running costs and affordability are key factors.
Due to their smaller size, 1.0-litre engines generally produce less power compared to larger engine options. However, advancements in technology, such as turbocharging and direct fuel injection, have allowed manufacturers to enhance the performance of these engines. It’s not uncommon to find 1.0-litre engines with power outputs ranging from 60 to 120 horsepower, depending on the specific design and tuning.

Factors to Consider When Selecting Car Engine Size
So now you understand the intricate workings of each engine car size, to the wider implications of choosing one type over another. Now let’s consider the key factors that should influence you in selecting the perfect car engine that aligns seamlessly with your lifestyle, preferences, and budget.
Operational Expenses
Generally, the larger an engine, the more fuel it consumes and the more emissions it produces, which, in turn, increase the road tax cost. If you prioritise low operating costs for city driving, a compact car with a 1.0-litre turbocharged engine could be ideal. However, for frequent long-distance drives, a larger, more powerful petrol or diesel engine could be more fuel-efficient.
Insurance for cars with smaller engines also tends to be less expensive, although this can differ based on the specific model.
For the Urban Driver
For frequent city driving, a car with a smaller engine is likely to be your best option. An overly powerful engine for city conditions might be unnecessary, and choosing a smaller one could lead to financial savings.
For the Motorway Driver
If the majority of your driving happens on motorways or duel carriageways, consider a medium-sized diesel engine. These are typically fuel-efficient and provide adequate power for overtaking maneuvers.
For the Fast Driver
If speed is your priority, a car with a high-capacity, powerful engine will be more suited to your needs. However, remember that many top-performing sports cars operate on around 2.0-litre engines, so this isn’t an absolute rule.
Environmental Factors
The engine size of a car doesn’t influence whether it incurs charges from emission zones like London’s ULEZ. Charges in such zones are determined by a car’s Euro standard, which indicates its level of emission cleanliness.
Is the Size of a Car Significant?
Indeed, the dimensions of a car significantly influence the performance of its engine. For instance, a 2.0-litre engine could propel a supermini swiftly, while the same engine may struggle to provide the same speed in a larger SUV. Thus, it’s essential to consider engine size in relation to the type of car that piques your interest, as well as your driving habits.
What Impact Does Engine Size Have on Car Insurance Costs?
Vehicles with larger engines often carry higher insurance costs, and this can be attributed to two primary factors. Firstly, given their increased power, these cars are perceived by insurance companies as more accident-prone compared to slower, city-driving cars. Secondly, their appeal to potential thieves elevates their risk profile, contributing further to increased insurance premiums.
