Worked example

Why a “2.0-litre” engine may be 1,998 cc

Model descriptions usually round displacement for readability. The technical specification gives the actual swept volume, which may be slightly above or below the badge description.

Displacement is not physical engine size

The figure refers to the total swept cylinder volume. It does not describe the external dimensions or mass of the complete engine.
