Domestic cars and joint-venture cars differ in engine quality, which is indeed a significant distinction between them. In the joint-venture car market, whether it's Japanese brands like Toyota and Honda, German brands like Volkswagen and BMW, or Korean brands like Hyundai and Kia, these companies have a relatively long history and strong engine technology. The annual 'Top 10 Engines' are mostly produced by these companies. More information about domestic engines is as follows: 1. Chinese manufacturers can produce excellent engines, but due to factors such as design, equipment, and materials, there is still a gap compared to the world's top standards. Therefore, there is still a considerable distance to fully independently design and manufacture outstanding engines. 2. China's automotive industry started late, and many companies initially relied on purchasing and reverse-engineering well-known, high-quality engines for their own design and development.

Domestic car engines, like the ones we've repaired, are mostly independently developed domestically or incorporate partially imported technologies, offering affordable prices. However, they may lack refinement in design and manufacturing details, such as material selection and sealing, leading to early-stage issues like abnormal noises or sludge accumulation. Joint-venture car engines typically benefit from foreign brand technology inputs, such as Volkswagen's EA888 or Toyota's hybrid systems, featuring more optimized structures, longer lifespans, and fewer fault codes during maintenance. Cost-wise, domestic parts are cheaper and easier to find, resulting in lower repair costs, making them more budget-friendly. In the long run, domestic engines have made significant progress, but joint-venture models still hold clear advantages in noise control and fuel economy, though the gap is narrowing. I recommend weighing your budget and driving habits when choosing a car.

I've driven both domestic and joint-venture cars, and I feel the engine differences aren't significant for daily driving. Domestic models like the Geely 1.4T have slightly sluggish starts, with fuel consumption around 8.5L, and the engine noise is more noticeable during highway acceleration. Joint-venture models like Honda's Earth Dreams offer smoother power delivery, quieter operation, and similar city fuel consumption but better overall fuel efficiency. Price-wise, domestic models are 10,000 to 20,000 RMB cheaper, with more affordable maintenance costs – oil changes and air filter replacements are hassle-free. If you prioritize comfort and quietness, joint-venture cars are better, but for my personal use over many years, the savings from domestic models have been well worth it when spent on maintenance.

Where Does Water Accumulation in the Back Seat of a Car Come From?

Detailed explanations for the causes of water leakage or even accumulation in the back seat of a car are as follows: 1. Damage or blockage of the vehicle's air conditioning drain pipe: The moisture inside the air conditioning system cannot circulate, turning into liquid that flows into the interior of the vehicle. 2. Leakage from the vehicle's sunroof: Water will flow into the interior of the vehicle, causing accumulation. 3. Poor sealing of the vehicle's doors: Damage to the door panels can lead to water splashing into the car when driving through waterlogged areas. 4. Human factors: For example, accidentally spilling water inside the car. If the water accumulation in the back seat is due to human factors, it is essential to clean it up promptly to avoid significant impact on the vehicle.

Can electronic driver's licenses be used in Guangzhou?

Electronic driver's licenses can be used in Guangzhou. Below is relevant information about the electronic version of driver's licenses: 1. Description: An electronic driver's license is a type of license designed to prevent situations where some drivers forget to bring their physical licenses, avoiding the embarrassment of not having a license and also applicable for simplified penalty procedures in traffic violations involving fines of three points or less. 2. Development Progress: On April 12, 2017, Yancheng traffic police introduced an "electronic driver's license," primarily to provide convenience to the public, not to advocate or encourage drivers to not carry their physical licenses. On May 10, 2021, the Ministry of Public Security held a press conference to announce 12 convenience measures under the "Do Practical Things for the People" initiative to deepen the reform of "streamlining administration, delegating power, and improving government services" in public security and traffic management, declaring that starting from June 1, 2021, electronic motor vehicle driver's licenses would be piloted in three cities: Tianjin, Chengdu, and Suzhou.

Can the vehicle inspection be done at any vehicle management office?

Vehicle inspection can be done at any vehicle management office. As long as it is within the vehicle's registration area, any vehicle management office can perform the inspection. Vehicle inspections can be conducted up to 60 days in advance, so it's important to schedule the time appropriately to avoid expiration. Once expired, there will be a fine and a deduction of 3 points. Before the inspection, it's also necessary to check for any traffic violation records. If there are any, they must be resolved; otherwise, the inspection will not be conducted. Below are the materials that should be brought for the inspection: 1. Original vehicle license and road/bridge card. 2. Copy of compulsory traffic insurance. 3. Road/bridge ticket. 4. Copy of the owner's ID card. 5. The vehicle itself.

What is the Car Brake Pedal?

Car brake pedal refers to the pedal used for braking. Below is a detailed introduction about car brakes: 1. Overview: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of running locomotives, vehicles, and other transportation tools or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. 2. Brake Pads: Car brake pads, also known as car brake linings, refer to the friction materials fixed on the brake drum or brake disc rotating with the wheel. The friction linings and friction blocks bear external pressure to generate friction, thereby achieving vehicle deceleration.

Why Shouldn't You Engage the Handbrake When Parking on Rainy Days?

The reason why you shouldn't engage the handbrake when parking on rainy days is that the handbrake and brake discs are prone to rust after coming into contact with water. Here are detailed explanations about automotive brakes: 1. Overview: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. 2. Brake Pads: Automotive brake pads, also known as automotive brake linings, refer to the friction materials fixed on the rotating brake drums or brake discs of wheels. The friction linings and friction blocks within them withstand external pressure to generate friction, thereby achieving vehicle deceleration.
