Why Do Chery Cars Consume More Fuel?

[EdwardLee]

The detailed reasons why Chery cars consume more fuel are as follows: Insufficient Tire Pressure: Tires are relatively easy to check, so they should be inspected first. If the tire pressure is insufficient, fuel consumption will increase. If the tire pressure is normal, then check the tire wear. Severe tire wear can often lead to slipping, which also increases fuel consumption. Engine Carbon Buildup: If there is a significant amount of carbon buildup in the engine over a short period, it can also cause higher fuel consumption. This situation is likely due to the use of substandard fuel. Driving Technique Issues: The driver's skill level, improper gear shifting, and excessive braking during driving can artificially increase engine power loss. Additionally, excessive braking leads to more frequent starts, as fuel consumption is very high during startup. Driving at low temperatures requires the engine to operate at normal temperatures. If the car is driven without preheating after startup, the engine remains at a low temperature, resulting in poor fuel atomization and incomplete combustion.

I've driven quite a few Chery models and found the high fuel consumption primarily stems from several key factors. Outdated engine technology is the main culprit, especially the 1.5L or 1.6L engines used in lower-end models, which have poor combustion efficiency and are particularly fuel-thirsty during frequent city starts. Improper transmission matching exacerbates the issue - automatic versions suffer from noticeable jerking that slows acceleration while consuming more fuel. Suboptimal aerodynamic design, like the uneven surfaces on early QQ models, creates doubled wind resistance at highway speeds. Additionally, the vehicles tend to be heavy, especially SUVs like the Tiggo series, where higher curb weight demands stronger power output and consequently increases fuel consumption. Many owners overlook minor details such as underinflated tires or clogged air filters, seemingly small issues that compound fuel economy problems. Fortunately, modern Chery models like the Arrizo series show improvements, and choosing newer models coupled with smooth driving habits can save significant fuel.

My own Chery car sometimes consumes quite a bit of fuel, with common reasons being the engine's inefficiency. Many older models use single VVT or single overhead camshaft engines, where incomplete combustion increases idle fuel consumption, especially noticeable when climbing hills or using air conditioning. Driving habits have a significant impact; sudden acceleration and hard braking both raise fuel consumption. I once managed to save 10% by adjusting my driving rhythm. Maintenance is also crucial; delayed oil changes or aging spark plugs make the engine work harder. The air conditioning system takes up a considerable portion of the power, and frequent use in hot weather exacerbates fuel consumption. I recommend regularly checking tire wear and the condition of filters, as simple maintenance can reduce fuel consumption. Chery's newer models like the Tiggo 8 have improved in fuel efficiency, with turbocharged versions showing more noticeable improvements.

From my understanding of automotive design, the high fuel consumption of Chery vehicles often stems from engineering limitations. Vehicle weight is a key factor—for example, the sturdy but heavy chassis materials used in entry-level SUVs require more powerful engines, which increases fuel consumption. Unoptimized aerodynamics, with high drag coefficients in early models, also contribute to higher fuel usage at high speeds. Improper tire selection or increased rolling resistance due to wear further impact fuel economy. Minor components like carbon buildup in the throttle body or faulty oxygen sensors, if not addressed promptly, can worsen fuel efficiency. Personally, choosing flat roads and maintaining a steady speed can help mitigate these issues. Newer models like the Jetour series have reduced weight and optimized shapes, delivering better performance.

In my commuting experience, the relatively high fuel consumption of Chery cars can be partially attributed to usage conditions. Running the AC at full blast in hot weather increases engine load, especially during frequent stops and starts in traffic jams, which consumes more fuel. Older engines like the 1.3L models lack sufficient power, requiring deeper throttle input when carrying passengers or climbing hills, resulting in wasted fuel. Neglected maintenance is common—clogged air filters or dirty fuel injection systems reduce combustion efficiency. Regularly checking tire pressure and using high-quality engine oil helps lower fuel consumption. High-speed driving exposes issues with significant wind resistance, keeping the car body clean can reduce drag. Chery has made notable improvements in recent years, with models like the Arrizo GX demonstrating better fuel economy in urban conditions.

I believe Chery's fuel consumption issues primarily stem from technical and user-end factors. Older engine models suffer from low thermal efficiency, especially in low-RPM high-torque configurations where incomplete combustion increases fuel usage. Suboptimal transmission calibration, particularly delayed gear shifts in automatic models, exacerbates idle consumption. Common user maintenance errors like delayed fuel filter replacement accelerate system aging. Heavy body designs with poor aerodynamics impose greater urban driving burdens. Opting for lightweight new models like the Tiggo series, combined with eco-driving modes (smooth acceleration avoiding sudden stops), can significantly improve mileage. Simultaneously maintaining proper tire pressure and lubrication - these daily habits alone contribute to fuel savings.
