What is the Difference Between Two-Wheel Drive and Four-Wheel Drive?

The differences between two-wheel drive and four-wheel drive: 1. Different driving methods: Two-wheel drive has two wheels as the driving wheels, connected to the vehicle's power system; four-wheel drive maintains all four wheels as driving wheels throughout the entire driving process. 2. Different differentials: The two-wheel drive differential allows the front and rear driving wheels to rotate at different speeds; in four-wheel drive, to drive all four wheels, all wheels need to be connected, and a central differential is added to adjust the speed difference between the front and rear wheels. A two-wheel drive vehicle uses either the rear wheels (or front wheels) as the driving wheels, with the front wheels (or rear wheels) as the driven wheels, and the driving and driven wheels remain fixed. A four-wheel drive vehicle can use either the rear wheels or the front wheels as the driving wheels, but not both the rear and front wheels simultaneously as driving wheels.

What is Wheelbase?

Wheelbase refers to the distance between the center of the front axle and the center of the rear axle of a vehicle, measured as the distance between two vertical lines passing through the centers of adjacent wheels on the same side of the vehicle and perpendicular to the vehicle's longitudinal symmetry plane. The length of the wheelbase is a very important parameter, as it significantly impacts both the ride comfort and performance of the vehicle. Additionally, it determines the vehicle's center of gravity. When choosing between a long or short wheelbase, it is advisable to base the decision on your specific driving needs. For family use, opting for a long-wheelbase version is generally a better choice. If you have minimal requirements for passenger space and desire a more dynamic driving experience, you may consider the short-wheelbase version.

What should be paid attention to when driving on the highway for the first time?

For the first time driving on the highway, the following points should be noted: 1. Conduct a vehicle inspection in advance, focusing on fuel, engine oil, tire pressure, lights, etc., and plan the route. It is also advisable to have an experienced driver with at least 3 years of driving experience accompany you; 2. The minimum speed on the highway should not be less than 60 km/h, and the maximum speed should not exceed 120 km/h. Do not drive below the speed limit. Driving below the minimum speed limit on the highway will result in a 3-point penalty; 3. Follow road signs and drive correctly in the appropriate lane. If you need to overtake, always signal in advance, check the rearview mirror, and then move into the overtaking lane. After completing the overtaking, follow the same steps: signal in advance, check the rearview mirror, and then return to the driving lane; 4. Maintain a safe distance. For novice drivers, due to lack of driving experience, misjudgments are more likely to occur. Therefore, it is important to control the speed and keep a considerable distance from the vehicle ahead. If you follow too closely, you may not have enough time to brake in case of any sudden situation with the vehicle in front.

Is There Any Damage to the Car When the Front Underbody Makes a Loud Clunking Sound?

If the front underbody makes a loud clunking sound, you should get out of the car to check for any fluid leakage. If there is no leakage and the car drives normally, the issue is not serious. However, if the underbody is severely impacted, a comprehensive underbody inspection is necessary, especially focusing on the front part of the vehicle, which includes the engine, transmission, oil pan, etc. Severe impacts may cause oil pan leakage, transmission damage, or abnormal noises in the drivetrain, leading to significant harm to the vehicle. After a severe underbody impact, if the oil pickup tube is damaged, affecting oil supply, the engine may produce abnormal noises (due to oil shortage). In such cases, do not continue driving; contact roadside assistance immediately. To prevent underbody impacts, you can take measures from two aspects: protective equipment and driving techniques. 1. Install underbody armor. 2. Install an engine guard. From a driving technique perspective, to protect the underbody, slow down when encountering speed bumps or rough roads, and always observe road conditions carefully when driving on unfamiliar routes, driving with caution.
