Engine sizes are usually rounded to the nearest tenth of a liter. For example, an engine with a displacement of 1,020cc will still be classified as a 1.0-liter engine, while an engine with a displacement of 1,160cc will be labeled as a 1.2-liter engine. Generally speaking, larger engines can draw in more fuel and air, resulting in greater power output, although the presence of a turbocharger can also affect this dynamic.
