The differences between 91V and 91W tires lie in their speed ratings and load indexes, with specific details as follows: Speed rating: The 'V' indicates that the tire can sustain a maximum speed of 240 km/h, while the 'W' denotes a maximum speed capability of 270 km/h. Load index: Both 91W and 91V tires can bear a load of 615 kg. Below is extended information about automotive tire specifications: Specification representation: Tires are crucial components of vehicles, coming in various specifications and models suitable for different vehicle types. Specification markings are typically found on the tire sidewall as a series of alphanumeric characters, representing tread width, aspect ratio, type, rim diameter, load index, and speed rating. Speed rating: Tire speed ratings are categorized from A to Z based on their maximum sustainable speeds, with the A class further divided into eight subcategories (A1-A8). The later the letter appears in the alphabet, the better the tire's performance.

Which is stronger, FAW or SAIC?

Comparison between FAW and SAIC. FAW has an earlier establishment and higher status: The predecessor of FAW Group was the First Automobile Works established in 1953, which can be considered the earliest automobile manufacturing company in China. Although SAIC Group's history can be traced back to 1900, SAIC was merely a machine repair shop at that time, and it wasn't until 1955 that the Shanghai Automobile Manufacturing Plant was officially established. FAW and SAIC have different operational models: As a state-owned automobile enterprise, FAW will never collapse, but precisely because it is a state-owned enterprise, the production enthusiasm of its internal employees is generally not very high. SAIC, on the other hand, is different. As the largest listed company in the automotive sector in China's A-share market, SAIC operates on a commercialized model, which means that SAIC employees need to work hard to earn corresponding rewards. FAW has a richer variety of brand models: Whether it's FAW Toyota and GAC Toyota, or FAW Volkswagen and SAIC Volkswagen, FAW has more brands or models in this regard. For example, Volkswagen Group's Audi also belongs to FAW, while SAIC can only get the Phideon based on the Audi A6L chassis as compensation. FAW Toyota controls Toyota's main models such as the Corolla, Prado, and RAV4, while GAC Toyota only has the Camry and Highlander.

Which websites are commonly used for browsing cars?

Driving Test Guide, Autohome app, Yiche, car channels of Tencent and MSN, etc. You can browse cars on apps like Driving Test Guide, Autohome app, Yiche, etc. Generally, the car channels of Tencent and MSN update the fastest. If you want to buy a car, it's best to visit the website of the car you're interested in to understand the basic information. For pricing, check the 4S store website, but it's even better to visit the store directly to get a clearer understanding of all aspects. Do more research: If you know nothing about cars and rely solely on what the salesperson tells you about the model, they will only highlight the positives. If you can't understand the configuration sheet yourself, it's essential to have some basic knowledge about the car before going to see it. At least understand which configurations are good and which are poor.

Can you cross the solid line when one side is solid and the other is dashed?

"Vehicles on the side with the solid line cannot change lanes, while vehicles on the side with the dashed line can change lanes. For double yellow lines, where one is solid and the other is dashed, vehicles on the side with the dashed line can temporarily cross the line, such as for overtaking or turning. Yellow lines are used to separate lanes in opposite directions and are typically painted in the center of the road, dividing it into two directions. Common lane markings are explained as follows: Single solid yellow line: Generally painted on roads with only one lane in a single direction or one motor vehicle lane and one non-motor vehicle lane, or in other hazardous areas where overtaking is prohibited. It prohibits vehicles from crossing or driving over the line in both directions. The single solid yellow line serves as the center divider for opposing lanes and has the same meaning as double solid yellow lines—both strictly prohibit crossing the center divider. Double solid yellow lines: Generally painted on roads with two or more motor vehicle lanes in a single direction and without a physical central divider. They also prohibit vehicles from crossing or driving over the lines in both directions. In other words, when there are two or more lanes on each side of the yellow solid lines, vehicles are not allowed to cross the double solid lines for any reason, including overtaking, making U-turns, or driving over the lines. Strictly speaking, these actions are traffic violations, and in the event of an accident, the driver will bear full responsibility."

Will the Air Conditioner Cool Without Starting the Engine?

"In ordinary fuel-powered vehicles, the air conditioner will not cool without starting the engine because the air conditioner in such vehicles is driven by the engine. If the car is not started, the air conditioner cannot be used. However, in electric vehicles, the air conditioner can be turned on even when the car is not started. When the car is not started, the air conditioner switch can be turned on, but the air conditioner does not actually work; it only blows air. This is because the air conditioner requires a significant amount of power, which the car battery cannot sustain. Therefore, if the engine is not running, the air conditioner automatically enters a protection mode and will not operate. The car air conditioning system is designed to cool, heat, ventilate, and purify the air inside the vehicle. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. Different types of air conditioning systems have varying layouts. Passenger cars commonly use an integrated heating and cooling air conditioning system, where components such as the evaporator, heater core, centrifugal blower, and control mechanisms are assembled together, forming the air conditioning unit. The car air conditioning controller is a control device for the car air conditioning system. It regulates the air conditioning system, enabling functions such as cooling, ventilation, and defrosting. All equipment is securely installed, with control devices and operating mechanisms that are flexible and easy to operate, ensuring safe and reliable performance."

What is the issue when the uphill stopping point is less than 50 cm?

In the subject two fixed-point parking, the announcement of less than 50 cm refers to the distance from the edge line being less than fifty centimeters but more than thirty centimeters during uphill fixed-point parking. In this case, 10 points are deducted. During uphill fixed-point parking, the distance from the edge line should be less than or equal to thirty centimeters, and the line must not be crossed. Uphill fixed-point parking is an assessment point in subject two of the driver's test. Uphill fixed-point parking requires stopping at a fixed position on a slope with a gradient of 10% or more and a slope length of 30 meters or more, testing the coordination of steering, braking, and clutch. After hearing the "uphill fixed-point parking" instruction, the vehicle should drive slowly and straight along the right side of the road, paying attention to the distance between the body and the right edge line. When the vehicle approaches the stopping pole at about 10 meters, it should slowly, accurately, and steadily approach the target position. Uphill fixed-point parking evaluation criteria: After the vehicle stops, if the front bumper is not aligned with the pole line and exceeds 50 cm forward or backward, it is a failure; After the vehicle stops, if the front bumper is not aligned with the pole line but does not exceed 50 cm forward or backward, 10 points are deducted; After the vehicle stops, if the body is more than 30 cm away from the road edge line, 10 points are deducted; if the body is more than 50 cm away from the road edge line, the test is failed.

What does D+/- mean in automatic transmission and how to switch?

Automatic transmission "D+" and "D-" refer to the manual mode of the vehicle. When the gear is in D position, move the gear lever to the left or right to switch to manual mode. In manual mode, you can change gears by operating "D+" and "D-". Pushing towards "D+" means upshifting, while pushing towards "D-" means downshifting. More details about automatic transmission D+/- are as follows: 1. Introduction 1: Although traditional automatic transmissions have advantages in operability and driving comfort, they do not have the freedom of manual transmission models. This is how the manual-automatic transmission came into being. 2. Introduction 2: While it has the function of automatic shifting, it also has the function of simulating manual shifting. Its emergence allows more models to be free from the constraints of traditional automatic transmissions, giving drivers the freedom of manual shifting and driving pleasure.
