Different transmissions endow a car with distinct "characteristics". Below is a detailed introduction: 1. AT - Automatic Transmission. Advantages: mature technology, reliable, with moderate shift comfort. Disadvantages: complex structure, higher maintenance and repair costs, and relatively higher fuel consumption. 2. CVT - Continuously Variable Transmission. Advantages: CVT is not suitable for aggressive driving, excels in fuel efficiency, and offers good shift comfort. Disadvantages: lacks sportiness, can handle smaller torque, and has average durability. 3. DCT - Dual-Clutch Transmission. Advantages: DCT performs exceptionally well in sporty driving, with fast shift response and excellent fuel efficiency. Disadvantages: First, the issue with DCT primarily manifests in dry DCTs, where frequent starts or heavy-load conditions can cause the clutch to overheat, posing safety hazards. Second, problems with clutch control precision and strategy can lead to excessive shift jerkiness, resulting in poor drivability and smoothness. Third, incomplete software development and testing, coupled with hardware wear, can degrade vehicle driving performance. 4. AMT - Automated Manual Transmission. Advantages: moderate shift comfort and excellent fuel efficiency. Disadvantages: noticeable shift "jerkiness" and occurrences of power interruption.

What is the correct method to decelerate when driving a manual transmission car at high speed?

The correct method to decelerate when driving a manual transmission car at high speed is: 1. First, release the accelerator pedal and apply the brakes to slow down; 2. Reduce the speed to an appropriate level based on the actual road conditions; 3. Depress the clutch pedal, shift the gear lever to the gear that matches the speed, and continue driving. A manual transmission requires the driver to manually shift the gear lever to change the gear meshing mechanism inside the transmission, altering the gear ratio to achieve speed changes. A manual transmission mainly consists of gears and shafts, generating speed and torque variations through different gear combinations. The principle is based on the leverage effect, where the largest diameter gear in the lowest gear with the longest radius amplifies the engine torque to assist the vehicle in starting forward movement.

Is the Vehicle License Permanently Valid?

Vehicle licenses are not permanently valid. The specific validity periods are divided into six years, ten years, and long-term. The supplementary page indicates the inspection validity period, which essentially marks the deadline for the annual review. Therefore, the validity period of the vehicle license is also linked to the annual review, varying for different types of vehicles. The motor vehicle license is the legal document permitting a vehicle to operate on the road, consisting of a license holder, main page, and supplementary page. The front of the main page displays the endorsed certificate core with black text, while the back features a photo of the vehicle. The supplementary page contains the endorsed certificate core. Issued by the vehicle management center, the vehicle license serves to verify the authenticity of vehicle information.

Should You Shift Directly to P Gear or First to N Gear Before Parking and Turning Off the Engine?

Before parking and turning off the engine, first shift to N gear, and then shift to P gear after turning off the engine. The correct parking sequence is to first press the brake to stop the vehicle, then shift to N gear, release the handbrake, and finally shift to P gear. The difference between P gear and N gear is that P gear has a parking lock mechanism, while N gear does not, but both have the nature of neutral gear. Before parking and turning off the engine, make sure the vehicle is no longer moving, has come to a complete stop, or the handbrake has been firmly applied. Otherwise, shifting to either N gear or P gear can cause damage to the transmission. When shifting gears while stationary, also ensure the vehicle is in a braking state to prevent any abnormal movement.
