When you’re looking at a car’s specification you may notice the term ‘d2’. What does this mean?

‘d2’ is simply a short way of saying ‘displacement’. In other words it’s a measure of the size of an engine. It’s usually expressed in litres.

There are a number of reasons why you might want to know the size of an engine. For example it can give you an indication of how much power the engine is likely to generate. A larger engine will usually generate more power than a smaller one.

The size of an engine can also give you an idea of how much fuel it is likely to consume. A larger engine will usually consume more fuel than a smaller one.

Finally the size of an engine can also give you an idea of how much noise it is likely to generate. A larger engine will usually generate more noise than a smaller one.

So there you have it – ‘d2’ simply stands for ‘displacement’ which is a measure of the size of an engine.
