B-segment cars: Also known as mid-size cars or Large-Family-Cars, with a wheelbase ranging from 2.7 to 3.0 meters, body length from 4.8 to 5.0 meters, and engine displacement from 1.5 to 2.5 liters. 2. According to the German car classification standard: a) A-segment cars include A0 and A00, typically referring to compact cars; b) B-segment cars are mid-size sedans; c) C-segment cars are premium sedans; d) D-segment cars are luxury sedans.

What is the wading depth of the Envision?

The maximum wading depth of the Buick Envision is 300mm. The wading depth of the Buick Envision is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when driving through waterlogged roads. Therefore, in terms of safe wading depth, SUVs and off-road vehicles have obvious advantages. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a reference when passing through waterlogged roads. If the air intake of the Buick Envision is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it can cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. Installing a snorkel can increase the height of the engine's air intake, thereby improving the maximum wading depth. If wading is unavoidable, the following safe and correct operations should be performed: Before driving through water, always turn off the auto start-stop function to prevent the engine from automatically restarting after stalling in water, which could cause severe damage due to water ingestion. Assess the underwater road conditions based on the passage of vehicles ahead and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. On roads prone to flooding, use warning water level markers, trees, or the wheels and doors of other vehicles as references to estimate water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half the height of the tires or the engine's air intake, do not proceed and choose an alternative route instead.

What is the reason for the delayed acceleration when stepping on the gas pedal, followed by a sudden speed increase after a few seconds?

Here are the reasons for the delayed acceleration when stepping on the gas pedal: 1. Carbon deposit issues: These include carbon deposits in the cylinders, throttle valve, spark plugs, and intake system. These components are directly related to the engine's power output. When there is excessive carbon buildup inside the engine, the car's ignition energy decreases, intake efficiency drops, and ultimately, the engine's power is reduced, resulting in sluggish acceleration and a muffled sound. 2. Fuel system issues: Using an incompatible fuel grade can lead to a decrease in the car's output power and reduced performance. Alternatively, if the fuel tank vent is blocked, or if the fuel tank switch, fuel filter, or fuel lines between the tank and carburetor are partially clogged, the required fuel supply cannot be met, leading to a lean air-fuel mixture and weak engine acceleration. 3. Intake system issues: Air is one of the engine's power sources. If the air filter is not cleaned in time after long-term use and becomes clogged, insufficient air intake will result in an overly rich air-fuel mixture, causing a drop in engine power.

How Many Subjects Need to Be Retaken After Driver's License Revocation?

After a driver's license is revoked, all subjects must be retaken. Generally, when the revocation period of a motor vehicle driver's license expires, all subjects need to be retested. The license can be reissued only after passing Subject 1, Subject 2, Subject 3, and Subject 4. Below is an introduction to the content of each subject: 1.

A score of 90 or above (including 90) is considered passing. 2. Subject 2: Field driving skills test (Subject 2) is conducted on-site with an actual vehicle. Results are categorized as pass or fail only. The test includes five mandatory items performed in sequence: reversing into a parking space, parallel parking, S-curve driving, right-angle turning, and starting and stopping on a slope. The full score is 100, with 80 or above (including 80) considered passing. 3. Subject 3: Road driving skills test (Subject 3) is conducted on a road or simulated site with an actual vehicle. The full score is 100, with passing scores varying by vehicle type: 90 or above for large buses, 80 or above for large trucks, and 70 or above for other vehicle types. 4. Subject 4: Safe and civilized driving-related knowledge test (Subject 4) is a written exam with a full score of 100. A score of 90 or above (including 90) is considered passing.

Will the validity period of driver's licenses be extended during the pandemic?

In the event of a pandemic, the validity period of learning driving certificates obtained before and during the pandemic will be uniformly extended, generally by three months. The following is relevant information about the vehicle license: 1. Introduction: The motor vehicle license is the legal document that permits a motor vehicle to drive on roads within China. The license consists of three parts: the license holder, the main page, and the supplementary page. The front of the main page is the signed certificate core, and the back is the photo of the motor vehicle, sealed in a plastic cover. The supplementary page is the signed certificate core. 2. Verification: The vehicle license verification system can verify the authenticity of the motor vehicle and query motor vehicle information to provide travel safety guarantees. By simply entering the basic information of the motor vehicle into the system, you can verify whether the motor vehicle is genuine. If the information matches, other details of the motor vehicle can also be verified.
