What is the weight of a sedan?

Generally, the load capacity of a family sedan ranges from 375 to 400 kg. The actual load capacity should strictly follow the weight indicated on the nameplate attached by the manufacturer at the time of production. The national standard sets the load capacity at 375 kg, meaning that the manufactured vehicle's load capacity cannot exceed this limit. Calculating based on the minimum standard of 375 kg, the car can accommodate four people weighing 150 pounds each and still have space for nearly 100 pounds of additional items (including fuel tank, spare tire, onboard tools, fire extinguisher, etc.). Below are the damages caused by overloading to the vehicle: 1. Reduced braking performance and increased non-safe zone distance. Many factors affect a car's braking distance, among which changes in vehicle load directly impact the length of the braking distance. Overloaded vehicles, due to increased inertia, require a longer braking distance. The extension of the non-safe zone distance can easily lead to traffic accidents; 2. Shortened lifespan of leaf springs and reduced vehicle passability. Overloading causes excessive stress on the leaf springs, leading to continuous bouncing during driving, which shortens their lifespan. Additionally, the excessive load causes the vehicle to sink overall, reducing the ground clearance and diminishing the car's ability to pass through certain areas; 3. Accelerated tire wear and deformation. When a car is overloaded, the tires bear excessive weight, leading to deformation. Increased friction also results in a shortened tire lifespan.

How to Distinguish Start-Stop Batteries?

Start-stop batteries can be identified by the following methods: 1. Appearance differentiation: Start-stop batteries have dedicated markings on their appearance, while ordinary batteries do not have such specific symbols. If the original battery is labeled with any of the following: ST, N55, Q85, S95, ISS, EFB, AGM, VRLA-BATTERY, start/stop, or idle stop system vehicle, it is a start-stop battery. 2. Weight differentiation: Start-stop batteries are heavier than ordinary batteries. When shaken, there is no sound of liquid inside. Installing ordinary lead-acid batteries in vehicles equipped with start-stop systems will shorten the battery's lifespan and introduce uncertain safety hazards during driving.

What Happens When Car RPM Is Too High?

The following are the impacts of excessively high car RPM: 1. Engine: Prolonged high RPM can place a significant burden on the engine due to overheating. If the vehicle outputs excessive torque at 3500-4000 RPM, driving or shifting gears at this RPM for extended periods can cause excessive torque on various components (engine, transmission, tires, etc.), leading to reduced lifespan. 2. Fuel Consumption: This results in increased fuel consumption, and higher speeds also reduce safety. When shifting gears at 3500-4000 RPM, the vehicle may experience a slight lurch forward; appropriately lowering the shift RPM can achieve optimal driving economy. Additional Information: 1. Rated Condition: The operating condition of the engine at rated power and rated RPM is referred to as the rated condition. 2. Rated Power: Rated power is the maximum effective power usage limit determined based on the engine's intended application.

How often should the transmission fluid be changed for the ATS-L?

Cadillac ATS-L transmission fluid should be changed every 2 years or every 40,000 kilometers. Here is some relevant knowledge about Cadillac: 1. Function: Transmission fluid is an oil product used to keep the gear system clean, specifically designed for the transmission. It ensures the normal operation of the transmission and extends the lifespan of the transmission components. 2. Design: The Cadillac ATS-L is a car launched by General Motors. It not only features an elongated and dynamic design but also maintains a 50:50 front-to-rear weight distribution, providing customers with a better experience. The front of the Cadillac ATS-L adopts Cadillac's new face design, with a wider grille and more prominent horizontal bars in the middle and surrounding lines.

In which year did automatic transmission cars become popular in China?

Automatic transmission cars became popular in China after 1950. An automatic transmission eliminates the need for constant gear shifting while driving, whereas manual transmission cars require continuous gear changes and clutch operation to adjust vehicle speed. Below is an introduction to automatic transmission features: 1. Acceleration: Pressing the accelerator pedal gradually increases the car's speed. 2. Manual Cruise: After stabilizing the speed, maintaining the accelerator pedal position keeps the car running at a steady speed, with minor adjustments possible based on road conditions to maintain a consistent pace. 3. Automatic Cruise: Once the speed is stable, activating the 'cruise control function' allows the driver to release the accelerator pedal, and the car will automatically maintain a constant speed. The function can be deactivated by pressing the brake or accelerator pedal again. 4. Gradual Deceleration: Gradually releasing the accelerator pedal results in a smooth speed reduction. 5. Emergency Deceleration: Releasing the accelerator pedal and pressing the brake pedal enables rapid deceleration.

What is the sign for slippery road ahead?

The sign for slippery road ahead has a yellow background, featuring a rear view of a car with zigzag tire tracks behind it. Additional information about warning signs is as follows: 1. Introduction: Warning signs are designed to alert drivers and pedestrians to potential hazards ahead. These signs typically have a yellow background with black borders and black symbols, shaped as equilateral triangles with the apex pointing upward. Upon seeing a warning sign, drivers should exercise caution, drive carefully, and reduce speed. 2. Legal regulations: In the People's Republic of China (excluding Hong Kong and Macau), warning signs feature black borders with a yellow background. In Sweden, Serbia, Bosnia, Croatia, Finland, Iceland, Greece, the Republic of Macedonia, and Poland, warning signs have red borders with an amber background. Climate factors influence color choices in these frequently snowy regions, where red-on-amber signs are more noticeable than red-on-white signs. The polar bear warning sign in the Svalbard archipelago was changed from a black bear on a white background to a white bear on a black background (both being triangular signs with red borders). Some countries that typically use white-background signs may opt for amber for road construction or other engineering-related signs.
