The BYD Han DM 2021 hybrid has a fuel consumption of approximately 4.7 liters per 100 kilometers. Poor driving habits: Habits such as weaving through traffic, sudden stops and starts, and driving at high speeds in low gear can significantly increase fuel consumption. Engine carbon buildup: Carbon buildup in the engine can also lead to higher fuel consumption. Low tire pressure: Underinflated tires or insufficient tire pressure can cause the car to consume more fuel. It's advisable to check tire inflation before driving, and using a tire pressure gauge can help. Maintaining proper tire pressure can reduce fuel consumption. Overloaded trunk: Carrying too many items in the trunk can also increase fuel consumption. Regularly clearing out unnecessary items from the trunk can help lower fuel consumption.

I've been driving this 2021 BYD Han DM hybrid for almost a year now. The most noticeable fuel consumption observation is that it averages 5.9 liters per 100 kilometers when the engine kicks in during battery depletion. During regular commutes with heavy city traffic, consumption might rise to around 6.2 liters, but on highways or in hybrid mode, it stabilizes between 5.7 to 5.8 liters. Compared to my previous pure gasoline car that easily consumed over 10 liters, the savings are substantial. The key advantage is not needing fuel when charging is available - overnight home charging covers my entire commute using electricity, saving hundreds on monthly fuel costs. Long-term maintenance isn't expensive either, mainly requiring regular battery and engine checks. I'd recommend paying attention to how driving conditions affect consumption. Overall reliability hasn't disappointed - neither traffic jams nor summer AC usage significantly impact its range.

As a tech enthusiast, I truly appreciate the plug-in hybrid system of the Han DM 2021. Its fuel consumption in charge-sustaining mode is approximately 5.9L/100km, thanks to the intelligent switching between the 1.5T engine and dual motors – using electricity at low speeds for fuel efficiency and switching to the engine at high speeds for optimal power generation. My own tests showed that frequent starts and stops in urban areas can increase consumption to around 6L, but overall, it's significantly lower than the average 8-10L of conventional fuel vehicles. Fuel efficiency also depends on driving habits, such as aggressive acceleration increasing consumption. For optimization, using pure electric mode more often is recommended; a full charge provides about 81 km of range, making short trips virtually fuel-free. In the long run, hybrid technology reduces maintenance costs, but don’t overlook tire and electronic control system upkeep.

What transmission does the Dongfeng Fengdu MX6 use?

Dongfeng Fengdu MX6 uses a CVT transmission, which has a relatively unique structure. The CVT transmission is a common type of automatic transmission with a very simple internal structure, consisting of only two pulleys and a steel belt. The steel belt can move along the pulleys, allowing the transmission to change gears and torque. The CVT transmission can achieve continuously variable transmission within a fixed ratio range without any jerking during gear shifts. However, this type of transmission cannot be paired with high-power engines. The CVT transmission relies on the friction between the steel belt and the pulleys to transmit power. If the engine torque is too high, the steel belt may slip. Therefore, CVT transmissions are typically used in family cars, not performance vehicles. The Dongfeng Fengdu MX6 has body dimensions of 4625mm in length, 1790mm in width, and 1735mm in height, with a wheelbase of 2630mm. It offers front-wheel drive and all-wheel drive options, and has a fuel tank capacity of 65L.

What does 102Y tire mean?

102 indicates a load index of 850kg, and Y means the maximum speed of this tire is 300 km/h. Some tires also have speed limit symbols marked with letters such as P, R, S, T, H, V, Z representing various speed limits. The following are the functions of car tires: 1. Support the full weight of the vehicle: Car tires support the full weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 2. Improve vehicle performance: Car tires transmit traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the car's power performance, braking performance, and off-road capability; they work together with the car suspension to cushion the impact during driving and dampen the resulting vibrations. 3. Prevent early damage to car components: Car tires prevent car components from suffering severe vibrations and early damage, adapt to the high-speed performance of the vehicle, reduce driving noise, and ensure driving safety, handling stability, comfort, and fuel economy.

What are the reasons for high fuel consumption in Wuling Rongguang?

Wuling Rongguang's high fuel consumption reasons are as follows: 1. Fuel consumption fluctuation caused by temperature influence: Generally in winter when temperatures are low, fuel consumption increases, almost comparable to fuel consumption when using air conditioning in summer. This is because low temperatures cause the engine to dissipate more heat. 2. Vehicle not maintained for a long time: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty oil results in poor lubrication, increasing resistance in various moving parts of the engine, requiring more energy to overcome this resistance, thus increasing fuel consumption. 3. Spark plugs need replacement: Spark plugs are often overlooked. Although they may still function, insufficient ignition energy can cause delayed ignition, missing the optimal ignition timing.

Can I Stop and Adjust When Pulling Over?

When pulling over, you cannot stop and then readjust; you must complete the maneuver in one attempt. Here are some key points to note for the Subject 3 driving test: 1. Pre-drive inspection: Before starting the Subject 3 test, you must walk around the vehicle for inspection. The test vehicle usually has two sensors, one at the front and one at the rear. Pause briefly near these sensors during the walk-around to ensure they detect you. 2. Adjust before operating: Adjust the car's mirrors and seat height, then confirm they are properly set. Ensure you can see the rear wheels through the mirrors. Fasten your seatbelt and verify the gear is in neutral before ignition. 3. Light simulation test: This requires flexible mastery of light controls. Practice light operation techniques during training and respond to test instructions within 5 seconds. 4. Shoulder checks: During Subject 3 practice or testing, perform proper shoulder checks. Remember critical observation areas during routine practice and execute these actions correctly during the test to avoid point deductions.

Does Manual AC Setting Affect Fuel Consumption?

Manual AC settings have minimal impact on fuel consumption. The core component of the AC system is the compressor, which is connected to the engine crankshaft via a belt. When the AC is off, the compressor pulley idles; when activated, the compressor engages, consuming engine power and increasing fuel usage. Behind the dashboard lies a heat exchanger with an accompanying fan. Since fan speed variations don't alter cooling capacity, they hardly affect engine fuel consumption. Key considerations for car AC usage: 1. Avoid minimum temperature settings: Many drivers excessively lower cabin temperature in hot weather, forcing continuous operation of the AC pump and blower. This not only increases fuel consumption and accelerates vehicle wear but also generates harmful emissions affecting occupant health. 2. Limit electrical device usage: Simultaneous operation of multiple in-car electronics can exceed 1KW power draw - nearly matching small cars' AC compressor consumption (typically 1.5KW). This electrical load converts directly into additional engine fuel consumption. Overloading electrical systems also accelerates vehicle deterioration.
