Why is the fuel consumption of Changan CC so high?

[IrisRose]

The reason for the high fuel consumption of Changan CC is that the car uses a relatively outdated engine technology, coupled with a larger body, resulting in higher fuel consumption. Here are some methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning malfunctions are a significant cause of high fuel consumption. Poor cooling performance will require increasing the fan speed and lowering the temperature to achieve a cooling effect. 2. Frequent sudden braking: Frequent sudden braking is the main reason for persistently high car fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid turning on the air conditioning too aggressively in small-displacement cars: For vehicles exposed to the sun, it is not advisable to turn on the air conditioning immediately after getting in the car. First, open the windows and set the fan to a higher setting without turning on the air conditioning to expel the hot air inside the car. After the vehicle has cooled down moderately, then turn on the air conditioning.

I think the high fuel consumption of the Changan CC is mainly due to its engine design and vehicle weight. The 1.5T engine delivers strong power but average efficiency, consuming a lot of fuel at low RPM in city driving. The heavy body weight and high air resistance also lead to significant fuel loss at high speeds due to wind resistance. The transmission matching is not ideal, and slow gear shifts force the engine to run at higher RPM, further increasing fuel consumption. I've tried regular maintenance, such as cleaning the air filter and switching to low-viscosity oil, which slightly reduced fuel consumption. Additionally, frequent start-stop cycles and air conditioning load also contribute to higher fuel consumption. It's recommended to check if low-resistance tires are used, as these adjustments can help lower the numbers. However, overall, the car prioritizes power performance over fuel economy.

I usually drive a Changan CC, and the high fuel consumption is mostly due to poor driving habits. Frequent sudden acceleration and hard braking, especially during short city trips, prevent the engine from reaching optimal operating temperature, leading to higher fuel usage. Using cruise control on highways can help maintain a steadier speed. Keeping the air conditioning on all the time, especially with full cooling in summer, increases the engine's workload and causes fuel consumption to soar. By adopting smoother driving techniques, such as gradual acceleration and deceleration, I've managed to reduce fuel consumption by 20%. Also, reducing unnecessary weight and keeping the trunk empty helps. Small adjustments in driving habits can save a lot on fuel costs and hassle.

I commute with the Changan CC, and the heavy traffic leads to high fuel consumption. Frequent starts and stops waste fuel, and the stop-and-go driving lowers engine efficiency. The air conditioning and audio system are on the whole time, increasing electrical load and engine burden. This worsens in extreme weather—hot days with strong AC increase fuel usage. Try to accelerate gently and remove unnecessary cargo; switching to low-resistance tires might help. Adaptability to the environment is key—avoid letting in-car devices distract you.

I noticed that the Changan CC has relatively high fuel consumption, often due to neglected maintenance. Insufficient tire pressure increases rolling resistance, leading to higher fuel consumption; engine oil that hasn't been changed for too long becomes thicker, reducing transmission efficiency; a dirty air filter restricts airflow, causing incomplete combustion and increased fuel usage. Regular maintenance, keeping the engine clean, replacing spark plugs or cleaning carbon deposits can improve efficiency. It is recommended that owners develop the habit of checking tire pressure and use high-quality engine oil to prevent issues from escalating.
