What is the fuel consumption per 100 kilometers for Volkswagen sedans?

Volkswagen sedans have a fuel consumption of 6.7~8.0L/100km. Actual fuel consumption depends on various factors, so the specific consumption should be based on actual usage. Apart from vehicle design and engine factors, the real waste of fuel is caused by the driver's habits, with frequent sudden braking and rapid acceleration being the primary reasons for increased fuel consumption. Improper driving habits: Fuel consumption is closely related to the driver's habits, such as idling for long periods without turning off the engine or frequent ignition, aggressive acceleration or frequent braking while driving, driving at low gear with high speed or high gear with low speed, etc. All these driving habits significantly "contribute" to increased fuel consumption. Abnormal tire pressure and tire wear: Low tire pressure increases friction between the tires and the ground, leading to greater resistance and higher fuel consumption. Normal tire pressure is around 2.5bar, which can be slightly reduced by 0.1bar in summer. Of course, tire pressure should not be too high either; it's best to inflate according to the vehicle's standard values. Additionally, if the tires are severely worn, frequent slipping can occur, which also increases fuel consumption. Fuel quality and carbon deposits: Many drivers overlook fuel quality. Poor-quality gasoline can lead to increased carbon deposits, which roughen the intake pipe walls, affecting air intake and the quality of the air-fuel mixture, causing a sharp rise in fuel consumption. Therefore, gasoline quality should not be ignored. Regular maintenance at 4S stores is a forward-looking investment, ensuring normal vehicle performance and saving unnecessary expenses in the long run.

How to Start the BYD Song?

To start the BYD Song, first, look around the vehicle to ensure safety before opening the door. Make sure the gear is in the parking position, press the brake pedal, and then press the one-button start key. Let the vehicle idle for about 30 seconds and check if any warning lights on the dashboard are abnormal. If everything is normal, shift to D gear to start moving. Precautions after starting are as follows: 1. Watch for obstacles: Carefully inspect the surroundings of the vehicle before starting, checking for any obstacles under the car or around the body. Cold starts require preheating the engine, with the preheating time depending on the temperature; generally, you can start once the idle speed returns to normal. Always remember to fasten your seatbelt and check if the driver's seat and rearview mirror positions are appropriate—adjust them if necessary. 2. Maintain a good sitting posture: A proper sitting posture isn’t just for show; it’s closely related to safe driving and comfort. A good posture requires the driver to rest their hands naturally on the steering wheel, with their back lightly touching the seat, eyes looking straight ahead, and feet naturally placed on the pedals. Avoid hunching over while driving. Sit facing the center of the steering wheel, with the weight of your wrists naturally resting on it, leaving enough room for movement in your elbows and knees. 3. Adjust the side mirrors: When adjusting the mirrors, your body should be in a natural driving position. Position the interior rearview mirror so that the scene is centered, showing a small part of your vehicle’s rear to help judge the distance and position of other vehicles. Adjust the side mirrors so that the horizon is centered horizontally, with a small part of your car’s body visible.

What is the normal pressure for a car's air conditioning system?

Under normal operating conditions of a general car's air conditioning system, the low pressure should be between 1.0-2.5 bar, and the high pressure should be between 15-18 bar. Here is some extended information on how to maintain a car's air conditioning system: 1. Comprehensive inspection of the air conditioning system: When using the air conditioning for the first time in summer, it is advisable to inspect the system first, such as checking the refrigerant and whether the air filter is too dirty through the reservoir, and whether there are any foreign objects in the radiator. 2. Pay attention to cleaning the air conditioning: Waiting until the air conditioning performance deteriorates before cleaning is not the right approach. The air filter should be replaced regularly. For example, in spring when there is more sand and dust, and willow catkins are flying around, these can stick to the filter, promoting bacterial growth and causing a musty smell in the air conditioning. Additionally, the condenser should be cleaned periodically, and the radiator should be removed for thorough cleaning.

What does 6AT transmission mean?

6AT transmission means the car has 6 forward gears, which means there are six sets of gear groups with different transmission ratios. Others include 4AT, 8AT, 9AT, and even 10AT. Although the preceding numbers are different, they are all derivatives of automatic transmission technology. Relevant information about the transmission is as follows: 1. Introduction: A device that changes the speed ratio and direction of motion. It is used to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a housing and several pairs of gears. 2. Function: During driving, to adapt to different working conditions, the car's driving force and speed need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the transmission is installed.

What does torque mean in car specifications?

Automotive torque refers to the torque force of a car, which is the moment output by the engine from the crankshaft end. Under the condition of fixed engine power, torque is inversely proportional to the engine speed. The faster the speed, the smaller the engine torque; the slower the speed, the greater the engine torque. It also reflects the load capacity of the car within a certain range. Relevant information about car engines is as follows: 1. Introduction: The car engine is the device that provides power for the car, serving as the heart of the vehicle. It determines the car's power performance, fuel economy, stability, and environmental friendliness. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. 2. Classification: Depending on the power source, car engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrid types.
