What is the Difference Between Showroom Cars and New Cars?

Differences in appearance and interior between showroom cars and new cars. Showroom Car Introduction: Showroom cars are provided by 4S dealerships primarily for display in exhibition halls. They are usually parked in the showroom for extended periods, with only stationary operations like starting the engine or activating lights. Frequent battery charging is required, which can cause damage to the car battery. Prolonged use as a showroom car may affect the battery's lifespan. New Car Introduction: New cars are entirely brand-new, both inside and out. From the exterior to the interior and components, they are superior to showroom cars. However, showroom cars are typically priced lower than new cars. When purchasing a vehicle, thorough inspection is essential. For popular models, this may be less critical, but for vehicles with longer storage periods, careful examination is necessary.

What are the effects of insufficient coolant on a car?

The effects of insufficient coolant on a car are: it can cause the engine or radiator to freeze and crack, leading to engine failure. It also affects the radiator's heat dissipation efficiency, failing to provide the necessary cooling effect. Without proper circulation, high temperatures can occur, and in severe cases, it may cause engine damage. Coolant is a type of cooling liquid containing special additives, primarily used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round. Generally, coolant should be replenished approximately every 20,000 kilometers. When adding coolant, avoid mixing different brands or colors, as their formulations may differ, leading to chemical reactions that can impair the coolant's effectiveness.

Is it okay if the windshield washer fluid spills outside?

It is okay if the windshield washer fluid spills outside. Windshield washer fluid is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. The functions of windshield washer fluid are: 1. Cleaning performance: effectively removes dirt and impurities; 2. Anti-freeze performance: the presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid; 3. Anti-fog performance: forms a single-molecule protective layer on the surface to prevent the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear field of vision; 4. Lubrication performance: contains ethylene glycol, which has high viscosity and can act as a lubricant, reducing friction between the wiper and the glass to prevent scratches.

What are the Key Technologies of Intelligent Connected Vehicles?

Key technologies include environmental perception, intelligent decision-making, control execution, V2X communication, cloud platform & big data, and information security. Environmental Perception Technology: In the field of environmental perception, deep learning has demonstrated significant advantages. Deep learning requires large amounts of data as training samples, imposing high demands on data collection and storage. It also has drawbacks such as unclear internal mechanisms and uncertain boundary conditions, requiring integration with traditional methods to ensure reliability. Currently, it is also limited by the processing capabilities of onboard chips. Cloud Platform & Big Data Technology: Cloud platform and big data technologies include cloud platform architecture and data interaction standards, cloud operating systems, efficient data storage and retrieval technologies, big data correlation analysis, and deep mining technologies. The cloud serves as the information hub for intelligent connected vehicles. Intelligent connectivity treats vehicles, pedestrians, and traffic facilities as information nodes, requiring different entities to upload collected information to the cloud for processing and distribution via cloud computing. Vehicles communicate with the cloud platform to send their position and motion information, and the cloud controller optimizes vehicle speed and gear based on road and traffic information to improve fuel economy and traffic efficiency.

What is the solution for a small amount of water entering the car window on a rainy day?

The solution for a small amount of water entering the car window on a rainy day is: 1. Try not to turn on electronic devices in the car, such as lights or starting the vehicle, to prevent short circuits caused by water; 2. Use the key to open the car door, and if it is still raining, cover the vehicle with an umbrella or waterproof cloth; 3. Take out wet carpets and other items from the car to dry outside; 4. Use a dry towel to wipe the damp areas; 5. Open all car doors for ventilation; 6. Sprinkle water-absorbing beads inside the car; 7. Continue absorbing moisture with dry towels, newspapers, rice, or other absorbent materials. The functions of a sunroof: 1. Change the traditional ventilation method; 2. Prevent exhaust fumes from entering the car; 3. Reduce wind noise; 4. Quickly lower the temperature inside the car; 5. Quickly remove fog inside the car; 6. Provide a wider view.

Is 10L/100km Fuel Consumption Normal for City Driving?

An urban fuel consumption of 10L/100km is normal. Fuel-saving methods: Insufficient tire pressure increases friction between tires and the road surface, leading to higher fuel consumption. Therefore, regularly check tire pressure, as different vehicle models and tires have different pressure standards. If tires are severely worn, slipping may occur, increasing fuel consumption, so replace tires when necessary. Check the braking system: Some vehicles may experience slight brake drag, effectively increasing the vehicle's load during driving and raising fuel consumption, so regular checks are essential. Regular maintenance and part replacements—such as air filters, fuel filters, and oil filters—should be performed every 5,000 kilometers or more, as a clogged air filter reduces airflow, leading to incomplete fuel combustion and lower fuel efficiency. Worn clutch plates, clutch pressure plates, and spark plugs that have been used for too long can also increase fuel consumption, so they should be replaced periodically.
