What is the typical fuel consumption per 100 kilometers on highways?
3 Answers
Highway fuel consumption varies depending on factors such as engine displacement and driving speed. For most sedan models, when driving at a speed of 100 kilometers per hour on the highway, the fuel consumption typically ranges from 6 to 10 liters per 100 kilometers. Below is an introduction to fuel consumption: Fuel consumption per 100 kilometers: This refers to the fuel consumed by a vehicle traveling 100 kilometers at a certain speed on the road. It is a theoretical indicator for vehicles. Manufacturers measure this value by using a dynamometer installed on the vehicle's chassis under controlled conditions, converting it into speed parameters, and then calculating the theoretical experimental fuel consumption per 100 kilometers for the model. Road condition fuel consumption: Also known as multi-condition road cycle fuel consumption, this is a fuel indicator calculated based on repeated tests where the vehicle is driven at specified speeds and times on designated roads. The standard specifies that each cycle includes various driving conditions, and records the driving conditions based on indicators such as gear shift timing, parking time, driving speed, acceleration, braking, and deceleration. The measured values obtained through this method are closer to real-world conditions.
I've been driving for over a decade, and fuel consumption is my top concern on highways. For regular family cars, highway fuel consumption typically ranges between 5-8 liters per 100 kilometers, and my 1.6L sedan averages 6.2 liters in actual tests. Fuel efficiency mainly depends on three key factors: maintaining a speed between 90-100 km/h is most fuel-efficient, as exceeding 120 km/h significantly increases wind resistance and fuel consumption; vehicle weight also plays a role, with a full load adding about 1 liter per 100 kilometers; and regularly checking tire pressure is crucial, as underinflated tires can increase rolling resistance by over 15%. Before long trips, I clear out unnecessary items from the trunk and always refuel at reputable gas stations—92 octane gasoline is perfectly adequate, with no need to blindly opt for higher grades.
Previously drove for Didi, and noticed significant differences in highway fuel consumption across different car models. Small-displacement sedans generally consume 5-7 liters, with models like the Fit (1.5L) achieving just over 5 liters. SUVs are typically higher, with compact SUVs like the CR-V averaging 7-9 liters, while larger models like the Highlander can reach 10 liters. Hybrids are indeed more fuel-efficient, with the Corolla Hybrid consuming just over 4 liters on the highway. I've observed that cruise control isn't as fuel-efficient as an experienced driver manually controlling the throttle, especially on slopes where the system tends to accelerate aggressively. It's advisable to take a break at service areas every two hours, as prolonged high-temperature engine operation can increase fuel consumption.
