What is the difference between 1.5L and 1.8L engines?
4 Answers
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.
When it comes to the difference between 1.5L and 1.8L engines, I have the most experience after driving to and from work every day for over a decade. The 1.5L small displacement is extremely fuel-efficient for city commuting, and you don't have to worry about wasting gas with all the stop-and-go traffic. It's very easy to drive, especially with sufficient power when starting. However, when taking the whole family out on weekends with lots of luggage and some steep slopes, it feels a bit underpowered, requiring you to step harder on the gas. In contrast, the 1.8L engine offers much stronger power, making highway overtaking effortless and climbing slopes feel like a breeze. Although the fuel consumption is slightly higher, running the air conditioning doesn't make it feel as sluggish. I've tried different models, and for daily city use, the 1.5L is economical enough. For friends who frequently drive on highways or carry heavy loads, don't hesitate to choose the 1.8L. In terms of maintenance, both are about the same, just check the spark plugs more often.
As someone who loves pursuing excitement while driving, I particularly enjoy comparing performance. The 1.8L engine has a slightly larger displacement, delivering more aggressive acceleration at high speeds. A quick press on the gas pedal is all it takes to surge ahead when overtaking, and it doesn't hesitate when climbing hills. On the other hand, the 1.5L is more economical, offering brisk acceleration for daily commutes and a smooth driving experience. However, if you're in a hurry on mountain roads, its power feels a bit lacking. The difference in torque is quite noticeable—the 1.8L has stronger explosive power and handles aggressive driving with ease. After trying some tuning modifications, the gap becomes even more apparent. Smaller displacements suit beginners or city driving, while those seeking power should go straight for the 1.8L, which also feels more stable during high-speed lane changes. Personally, I drive the 1.8L on the outer ring roads, and it never feels sluggish.
When buying a new car, I always carefully consider my budget. The 1.5L engine is usually cheaper and has lower fuel consumption, saving a significant amount on gas annually, making it ideal for commuting. The 1.8L, though slightly more expensive, offers stronger power, making it effortless for long-distance driving or hauling goods, but maintenance and fuel costs are higher. Considering car insurance and long-term maintenance, the 1.5L is more economical, especially when gas prices rise. Having used several models, I find smaller displacement engines more agile for city driving and parking, saving unnecessary expenses. If your budget is tight, go for the 1.5L; if you need higher load capacity, choose the 1.8L, but don’t overlook mileage costs.
