The A-pillar of a car is located between the front windshield and the driver's side window; the B-pillar is between the driver's side window and the rear side window. The functions of the A and B pillars in a car are as follows: 1. A-pillar: It must withstand and disperse the impact force caused by a frontal collision. If the A-pillar is designed to be particularly thick, it will greatly increase the A-pillar blind spot for the driver, obstructing part of the turning view, especially during left turns. Therefore, for the A-pillar, it should be as small as possible while meeting sufficient strength requirements to ensure adequate visibility for the driver. 2. B-pillar: It mainly withstands side impacts. Since there is not enough crumple zone on the side of the car body, sufficient strength and stiffness of the B-pillar are crucial factors in protecting the driver's safety during a side collision.

Below is an introduction about displacement: Classification of displacement: In China, automobiles are classified based on their displacement size. Mini cars have a displacement of 1.0L or less; ordinary cars have a displacement ranging from 1.0L to 1.6L; mid-size cars have a displacement ranging from 1.6L to 2.5L; upper mid-size cars have a displacement ranging from 2.5L to 4.0L; and luxury cars have a displacement of more than 4.0L. Automobile displacement: Displacement is a specialized term in hydraulic transmission, referring to the volume of fluid inhaled or discharged per stroke or cycle. Automobile displacement is an important parameter for measuring a car. Some domestic cars do not have the above-mentioned model markings on the rear, but their displacement is generally indicated on the body or rear of the car.

How to Check the Battery Level of a Car?

You cannot directly see the exact battery level of a car battery, but you can determine whether the battery has power by observing certain phenomena. To be more precise, you can assess the current state of the battery. On the surface of the battery, there is an inspection hole (also known as a magic eye), which can be used to determine the battery's current state. Green or blue indicates a good condition; black or red means the battery needs charging; white suggests insufficient electrolyte, and the battery needs replacement. The colors of the inspection holes may vary depending on the battery manufacturer. Generally, there will be an explanation on the battery's surface. One important thing to note is that if the battery has already been over-discharged, relying solely on the car's charging system is insufficient because it takes about 20 hours to fully charge. In such cases, you will need to use a battery charger. Another method is to measure the battery voltage with a voltmeter. A voltage of 12.6V indicates a charge level of over 95%; below 11.8V means the battery is dead; and below 9.6V indicates the battery is completely discharged and needs replacement.

What materials are needed for car pickup?

Generally, only ID card, driver's license, and bank card are required for car pickup. The following is an introduction to precautions for car pickup: When picking up the car, pay attention to the mileage reading on the odometer, usually between 20-80 kilometers. Check if there are any debris in the radiator, if the protective covers and plastic sheets on the front seats are complete, and if there are any stains on the driver's seat and dashboard. When placing an order, pay attention to whether there is a long gap between the delivery date and the pickup date. If the gap is too long, the car might be a display car (placed in the showroom for guest viewing) or a refurbished car (used for test drives). Gifts are not redeemed on the spot. You can ask the 4S store to issue an IOU; also, when picking up the car, make sure to check if all the items you are supposed to have are complete; for example, whether the documents are in the information package, as without the documents, you cannot get the license plate; some car dealers mortgage the vehicle certificate to the bank, and the owner may not receive the certificate when picking up the car. What the owner needs to do is to inspect the car first and not pay if the documents are missing.

Is There Compensation for Replacing the Transmission in a New Car?

The revised Consumer Rights Protection Law stipulates: For household automotive products, if major components such as the engine or transmission exhibit quality defects within 60 days from the date the seller issues the unified motor vehicle sales invoice or within 3,000 kilometers of driving, the seller or manufacturer of the household automobile shall, upon the consumer's request, provide a full vehicle replacement or refund, and compensate for losses in accordance with the law. As one of the three most critical components in a vehicle, the transmission, whether in a new car or not, entitles the owner to manufacturer compensation as long as the issue arises within the warranty period. This is also mandated by the national Three Guarantees policy. The Three Guarantees policy, short for "return, replacement, and repair," is a retail commercial enterprise's commitment to servicing faults caused by product quality issues, not due to improper use or storage by the user. Article 19 of the Three Guarantees policy specifies that during the warranty period of a household automobile, if each repair (including waiting time for spare parts) exceeds five days due to quality issues, the consumer should be provided with a substitute vehicle or reasonable transportation cost compensation. The repair duration is calculated from the time the consumer and the repair facility agree on the repair until its completion. Any repair occupying less than 24 hours is counted as one day. Additionally, if the engine or transmission is replaced twice, or if the same major component of the engine or transmission is replaced twice due to quality issues and still fails to function properly, the consumer has the right to choose a refund.

How Long Does It Take to Become Proficient at Driving?

Everyone has different innate conditions and levels of effort. Some people can start driving the corresponding vehicle on the road from the day they get their driver's license. Generally, there won't be any major issues. Driving on city roads, as driving time accumulates, various safety operations gradually become instinctive reactions. It can take as short as a month or as long as a year to reach a proficient level of driving. Familiarize yourself with the basic performance of your daily driving vehicle, including emergency braking at high speeds, rapid acceleration at various basic speeds, braking on slippery surfaces, and the maximum safe speed on wet roads. Understand the vehicle's limits to ensure you can make judgments in dangerous situations: Assess whether the vehicle's current state has sufficient capability to avoid collisions; develop basic safety awareness, including perception of the vehicle ahead, anticipation of lateral vehicle movements, understanding the space required for your vehicle's limit lane changes, checking the inner (outer) rearview mirror during emergency braking to ensure safety behind, and frequently checking the rearview mirror.
