What is the fuel consumption per 100 kilometers for a 1.5L naturally aspirated engine?
3 Answers
1.5L naturally aspirated engine consumes 6~8 liters per 100 kilometers. When driving on highways at a speed of around 90km/h, the fuel consumption is about 6.5L/100km; the combined fuel consumption for urban and suburban roads is about 7.5 liters. The following is an introduction to displacement: 1. Introduction: Displacement, a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or discharged per stroke or cycle. Car displacement is an important parameter to measure a car. Some domestic cars do not have the car model marked on the rear, but the displacement is usually indicated on the body or rear of the car. It is generally expressed in liters (L). Engine displacement is one of the most important structural parameters, more representative of the engine size than the cylinder diameter and number of cylinders, and many indicators of the engine are closely related to the displacement. 2. Large displacement: Generally, a larger displacement means the engine releases more energy per unit time (converting the chemical energy of fuel into mechanical energy), which means better "power performance," so SUVs and sports cars usually have relatively larger displacements. Generally, the larger the displacement, the higher the fuel consumption per 100 kilometers.
I've driven several 1.5L naturally aspirated cars, and fuel consumption really can't be generalized. My old Corolla averages about 7-8L/100km in city driving, dropping to around 5.5L on highways, while my friend's Fit is noticeably more fuel-efficient. The key factor is vehicle weight – a 1.2-ton car can consume 1L/100km less than a 1.4-ton one. Transmission also makes a big difference; manuals typically save 0.5L/100km compared to CVTs, though clutching in traffic gets tiring. Don't overlook tire pressure – I once burned an extra 0.7L/100km due to underinflated tires. I recommend checking the Xiaoxiong Fuel Consumption APP for same-model data; it's much more reliable than guessing, as real-world owner-tested figures are more truthful than manufacturers' claimed values.
As a salesperson who frequently travels long distances, I keep a detailed record of my Nissan Sylphy 1.5L's monthly fuel expenses. Maintaining a steady speed of 60-80 km/h on flat roads is the most fuel-efficient, with the dashboard showing only 4.9L; turning on the AC in summer immediately increases it to 6.8L. The most extreme was when I rushed at 120 km/h once, and the fuel consumption directly exceeded 7.5L. When refueling, don’t just look at the octane rating—I’ve compared private gas stations with Sinopec and PetroChina, and the actual difference on the same route can be 0.3L. Now I’ve learned: anticipate road conditions to brake less, switch to 0W-20 low-viscosity oil, and the fuel savings over six months are enough for a maintenance service.
