What are the differences between 1.4L and 1.5L displacement?
2 Answers
The differences between 1.4L and 1.5L displacement are as follows: 1. Different engine efficiency. The 1.4L engine is much more efficient than the 1.5L engine. For example, engines using aluminum alloy materials are generally more efficient than cast iron engines, and engines with variable valve timing and direct injection technology are more efficient than those with intake manifold injection technology. 2. Different engine fuel consumption. The fuel consumption of an engine is determined by factors such as displacement, manufacturing process, and control technology. High-displacement engines may achieve fuel consumption levels similar to low-displacement engines.
I've been driving for many years and have compared cars with 1.4L and 1.5L engine displacements. The 1.5L has a slightly larger displacement, with increased engine cylinder volume, providing more robust power output. The acceleration feels smoother, especially during highway overtaking, where the response is quicker and less likely to get stuck midway. In terms of fuel consumption, the 1.5L might consume a bit more in urban areas, but the difference is minimal. For example, my Nissan with a 1.5L engine averages 7.8L/100km, which is about 0.5L higher than my friend's 1.4L Corolla. However, modern cars with turbocharging technology have narrowed this gap. Smaller displacement cars are more agile in congested areas, while larger displacements are better suited for long trips, offering more stability when carrying passengers or cargo. Maintenance costs are similar for both, so don't overthink which one to choose—both are reliable for daily driving. Personally, if you're on a tight budget, prioritize the 1.4L to save on fuel costs. If you prefer better performance, go for the 1.5L.
