What is the reason for the new Haval H6's fuel consumption of 21 liters?
3 Answers
Haval H6 new car high fuel consumption reasons are as follows: Abnormal tire pressure: If it is found that the vehicle's coasting distance is significantly shortened during driving, the tire pressure should be checked to see if it meets the standard. If the tires are underinflated, fuel consumption will also increase. The tires should be properly inflated in a timely manner. Tire wear: Check the degree of tire wear. If the tires are severely worn, slipping will frequently occur, increasing fuel consumption. New tires should be replaced when necessary. Bearings and braking system: If abnormal noises are heard from the wheels during driving or starting, the bearings and braking system should be promptly checked for faults. If the wheels do not rotate normally, it will affect the vehicle speed and increase fuel consumption.
I've been driving for several years and seeing the new Haval H6's fuel consumption reach 21 L/100km is indeed abnormal. It's normal for a new car to have slightly higher fuel consumption during the break-in period, and SUVs naturally consume more fuel, but 21 L/100km is way too high. Possible reasons include driving habits, such as frequent sudden acceleration and braking right after picking up the car, which puts a heavy load on the engine and causes fuel consumption to skyrocket. Or, insufficient tire pressure increases rolling resistance—check if the tire pressure meets the standard. Another possibility is fuel system issues, such as faulty sensors or an inefficient fuel delivery system in the new car. It's recommended to visit a 4S shop for a computer diagnostic test to rule out mechanical risks. Also, ensure the calculation method is correct—short single trips can easily show higher readings, so try a continuous highway drive to observe the average fuel consumption. Daily driving tips like smooth acceleration and braking, minimizing AC use, and regular maintenance (such as timely oil and filter changes) can gradually stabilize fuel consumption. The first few thousand kilometers are critical for a new car—handling it well will bring fuel consumption down to a reasonable level.
When I first bought my new Haval H6, I also encountered the strange phenomenon of fuel consumption soaring to 21 liters per 100 kilometers. I was really frustrated at the time—a new car shouldn’t be this wasteful on fuel. Looking back, it might have been related to my driving habits, such as aggressive acceleration in city traffic jams and frequent speed changes, which significantly increased fuel consumption. There was also the issue of the new car’s break-in period; initially, the engine and transmission weren’t running smoothly, so higher fuel consumption was natural. But 21 liters is clearly unreasonable—it’s worth checking tire pressure and fuel quality. Some owners use low-quality gasoline, leading to incomplete combustion and higher fuel consumption. Additionally, check if the air conditioning is set too high or if the car is overloaded with a fully packed trunk. In terms of measurement, calculating fuel consumption based only on short trips can inflate the numbers—averaging it out over a long-distance drive will give more accurate data. After the break-in period, fuel consumption usually stabilizes around 10-15 liters; 21 is extreme and might indicate a defect in the vehicle itself. It’s best to visit an authorized service center early to check if the ECU system is malfunctioning. Avoid aggressive driving and maintain steady throttle control to bring fuel consumption down. Don’t neglect regular maintenance—changing the engine oil promptly can help a lot.
