What is the Difference Between 1.5L and 1.8L Displacement?
2 Answers
1.5L and 1.8L displacement have the following differences: 1. Different fuel consumption: The 1.5L displacement has relatively lower fuel consumption, while the 1.8L displacement has higher fuel consumption. 2. Different power output: The 1.5L displacement provides relatively smoother power, whereas the 1.8L displacement delivers stronger power. Displacement is a specialized term in hydraulic transmission, referring to the volume of fluid inhaled or discharged per stroke or cycle. Most domestically produced passenger cars have a model designation consisting of pinyin letters and Arabic numerals at the rear, which includes the following three parts: The first part consists of 2 or 3 pinyin letters, serving as the code to identify the manufacturer's name. For example, CA behind Hongqi sedans represents FAW, and QC behind Flyer sedans represents Qinchuan. The second part, following the pinyin letters, usually includes 4 Arabic numerals. For passenger cars, the first digit on the left is 7, and the middle two digits indicate the engine displacement of that model. For instance, 15 denotes an engine displacement of 1.5 liters, and 18 denotes 1.8 liters. After the digits representing displacement, there is an additional digit indicating the manufacturer's self-defined product sequence number.
When I was buying a car, I also struggled between the 1.5L and 1.8L options. The most obvious difference is fuel consumption. My friend's 1.5L car consumes just over 7 liters per 100 kilometers in city driving, while my old 1.8L Corolla consistently uses at least 8.5 liters. On the highway, the 1.5L engine runs at lower RPMs and is quieter. In terms of power, the 1.8L certainly has more confidence, especially when fully loaded with the AC on or climbing hills. However, many current 1.5T turbocharged engines outperform the old 1.8L naturally aspirated ones. As for drawbacks, the 1.8L incurs about 200 yuan more in annual vehicle and vessel tax, and nowadays, new cars are mostly dominated by 1.5T engines.
