What is the difference between 1.4 and 1.5 displacement?
2 Answers
There are differences in terms of power and efficiency. Below are the specific details: Power aspect: For 1.4L and 1.5L engines produced by the same manufacturer, the difference is not significant. The 1.5L naturally aspirated engine might have slightly more horsepower and torque than the 1.4L engine, but overall, the difference is minimal, and the daily driving experience is essentially the same. Efficiency aspect: Whether a 1.4L or 1.5L engine is more efficient largely depends on the manufacturing, control technology, and materials used. For example, engines using aluminum alloy materials are generally more efficient than those using cast iron. Engines with variable valve timing and direct injection technology are more efficient than those with intake manifold injection technology. Therefore, a 1.4L engine could potentially be much more efficient than a 1.5L engine.
Having driven cars with various engine displacements, I think the main differences between 1.4 and 1.5 liters lie in power and fuel consumption. The 1.5-liter engine usually offers more horsepower and quicker acceleration, making it more responsive during highway overtaking. On the other hand, the 1.4-liter is more fuel-efficient, especially in urban traffic, with an average fuel consumption about 0.5 liters lower per 100 kilometers. However, the difference isn't huge, as many modern cars use turbocharging technology to narrow the gap. In practical driving, if you frequently drive on highways or prefer a more powerful experience, the 1.5-liter might be better. But for daily commuting, the 1.4-liter is more economical and has quieter engine noise. When choosing a car, it's best to test drive and compare—don't just focus on displacement, but consider the overall driving experience.
