What is the difference between 1.5L and 1.8L engines?

[LukeMarie]

The differences between 1.5L and 1.8L engines are mainly reflected in three aspects: displacement, power, and fuel consumption: 1. The 1.8L engine has a larger displacement than the 1.5L engine. A larger displacement means greater vehicle power, similar to the difference between an 80kg and a 50kg weight class in weightlifting or boxing. 2. The 1.8L engine provides more power than the 1.5L engine. Power includes aspects such as vehicle acceleration and top speed, meaning a 1.8L car will feel more powerful when driven. 3. The 1.8L engine consumes more fuel than the 1.5L engine. Displacement is a crucial structural parameter that comprehensively measures the size of an engine. The performance indicators of an engine are closely related to its displacement. Generally, the larger the engine displacement, the higher the power output. Unit displacement is often used as a basis for evaluating the size of different engines. The sum of the working volumes of all cylinders in a multi-cylinder engine is referred to as the engine displacement.
