What is the average fuel consumption per 100 kilometers on highways?
2 Answers
Highway fuel consumption per 100 kilometers depends on the vehicle's displacement. For example, a 1.8L manual transmission car typically consumes about 6-7L/100km, while an automatic transmission version consumes around 8-9L/100km. Below are specific factors affecting fuel consumption: Vehicle Condition: Besides regular cleaning, proper maintenance and timely repairs are crucial. Driving Habits: Poor driving habits waste fuel unnecessarily, such as carrying excessive cargo, driving with windows open at high speeds, sudden acceleration and harsh braking, all of which increase fuel consumption. Road Conditions: Urban driving consumes about 20% more fuel than test track conditions, mainly due to frequent starts and stops, waiting at traffic lights, and gear shifting.
I often drive on highways for trips. As a young person who enjoys road trips, I've noticed that fuel consumption per 100 kilometers largely depends on the car. When driving my compact sedan at a steady speed of around 90 km/h, the fuel consumption can be kept at about 6 liters. However, if I accelerate beyond 120 km/h or carry more load, the fuel consumption can soar to 8 liters. There are quite a few influencing factors: air resistance is the biggest factor—higher speeds mean greater wind resistance and increased fuel consumption; insufficient tire pressure or delayed maintenance can also raise fuel consumption; in terms of driving habits, avoiding frequent lane changes and sudden braking can save some fuel. It's advisable to regularly check tire pressure, maintain the engine periodically, and maintain good habits, which can make long-distance driving more fuel-efficient and safer.
