Vehicles over 15 years old require inspection every six months. Relevant details are as follows: 1. Inspection regulations for small passenger cars. Vehicles under 6 years are exempt from inspection but must obtain a free inspection exemption certificate every 2 years (dual-certificate integration). Vehicles over 6 years require annual inspection. 2. Vehicle annual inspection refers to mandatory testing for all vehicles with official license plates and registration certificates, equivalent to an annual physical examination according to the "Technical Conditions for Motor Vehicle Operation Safety". Additional information: 1. The inspection includes exhaust emission testing (checking oxygen sensors and catalytic converters). Their optimal operating temperature is 400-800°C, so warming up the vehicle in the inspection area beforehand can increase the pass rate. 2. Before the inspection, owners should clean the vehicle body, engine compartment, and chassis in advance to facilitate the inspection process and improve the chances of passing.

What are the reasons for the discontinuation of the Volkswagen Beetle?

The main reason for the discontinuation of the Volkswagen Beetle is the gradual decline in sales in recent years. This model can no longer compete with some SUV models in the eyes of consumers. Although the car has now been announced as discontinued, Volkswagen released a final edition before its discontinuation. Here are the specific reasons: 1. Reason one: The interior design of the Beetle is relatively outdated. Although it is well-designed, it lacks the eye-catching appeal of its exterior, overall missing a sense of technology and luxury. 2. Reason two: The front row space is very large, with spacious and bright driver and passenger seats, but there is insufficient storage space, and the rear seats are very cramped, only suitable for small children or storing items. 3. Reason three: Although the latest Beetle is produced on Volkswagen's MQB platform, equipped with 1.2T and 1.4T turbocharged engines and matched with a 7DSG dual-clutch transmission, the power output is only 105-150 horsepower, which is relatively weak. The car starts slowly, and the transmission responds sluggishly. Even when the accelerator is pressed hard, it takes a while for the power to start delivering, and the fuel consumption is not low.

What is the battery capacity of Li Auto?

The Li ONE has a 40 kWh battery, providing a pure electric range of only 120 km. Here are some specific details about Li Auto: 1. BYD Tang: The BYD Tang with a 22 kWh battery can run 100 km (NEDC), and beyond that, it relies on fuel. 2. Actual usage: The physical capacity of the battery pack is 40.5 kWh, but the actual usable capacity (displayed as 100%-0%) is 33.2 kWh. Therefore, it can run 180 km (NEDC) on 33 kWh and 150 km on 27.6 kWh before switching to fuel for power generation. 3. The significance of a large battery and reserved capacity lies in battery safety and longevity, ensuring smooth pure electric driving even at low battery levels, and relatively minor performance degradation.

Does fatigue driving result in penalty points?

Fatigue driving incurs a penalty of 6 points. Detailed information about fatigue driving is as follows: 1. Symptoms of fatigue: When driving a vehicle, as speed increases or during prolonged high-speed driving, the driver may experience varying degrees of fatigue. At high speeds, the driver's attention is highly focused, leading to prolonged mental tension. As speed continues to rise and driving time extends, the driver gradually feels fatigued. On highways, the monotonous road environment, minimal traffic interference, stable speed, and low noise and vibration frequencies can induce drowsiness, leading to what is known as "highway hypnosis." Thus, high-speed driving can easily cause driver fatigue. 2. Decline in judgment: Fatigue while driving reduces judgment, slows reaction times, and increases operational errors. When slightly fatigued, the driver may shift gears untimely or inaccurately; moderate fatigue leads to sluggish movements and sometimes even forgetting operations; severe fatigue may result in subconscious actions or brief sleep episodes, potentially leading to loss of vehicle control. Fatigue manifests as blurred vision, soreness in the back, stiff movements, swollen hands or feet, lack of focus, slow reactions, incomplete thinking, distraction, anxiety, or irritability. Persisting in driving under such conditions may lead to traffic accidents.

What is the wading depth of the Lavida?

Lavida wading depth is 300mm. Here is extended information: 1. Lavida: Lavida (LAVIDA) is Shanghai Volkswagen's first independently developed A-segment car, launched in June 2008, and is an important model in Volkswagen's global product strategy. 2. Wading judgment: When the water depth is one-third of the tire height, you can pass with confidence. As long as the operation is correct, it will not cause unnecessary losses. When the water depth exceeds half of the tire height, you need to be careful because this situation can easily cause water to enter the car. If the wading depth exceeds the bumper, you should be vigilant while driving to avoid water entering the engine.

What does Volkswagen's indirect tire pressure monitoring mean?

The tire pressure for the Volkswagen Jetta is 2.2-2.5 bar. Strictly speaking, tire pressure refers to the air pressure inside the tire. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components. Hazards of insufficient tire pressure: Increases friction coefficient with the road surface, leading to higher fuel consumption; results in heavy steering and deviation, posing safety risks; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, leading to delamination or cord breakage, excessive friction with the rim causing damage to the bead area and abnormal wear; increases tire deformation, leading to sidewall cracks and flexing motion, causing overheating, rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.

Is There a Difference Between Summer and Winter Windshield Washer Fluid?

There is a difference between summer and winter windshield washer fluid. The summer version typically contains insect-cleaning agents in the cleaning solution, which not only cleans the car's windshield but also quickly removes insect residue from impacts. Winter windshield washer fluid is an antifreeze-type cleaning solution, ensuring it does not freeze or damage car components even when temperatures drop below -20°C. There is also an ultra-antifreeze type that remains unfrozen at -40°C, directly dissolving frost and quickly spreading across the windshield to maintain clarity and restore a wide field of vision. This type is suitable for extremely cold regions in the northernmost parts of the country. Features of windshield washer fluid: Cleaning performance - It is formulated with various surfactants and additives. Surfactants typically provide wetting, penetration, and solubilization functions, enabling effective cleaning and stain removal. Antifreeze performance - It significantly lowers the freezing point of the liquid, preventing freezing and quickly dissolving frost. Anti-fog performance - It forms a single-molecule protective layer on the glass surface, preventing fog droplet formation and ensuring clear, transparent windshields with unobstructed visibility.
