What Issues Should Be Noted for a New Car?

How to Check if a Car is New?

When buying a car, you can determine whether the car is new through the following methods. 1. First, check the mileage: Generally, the mileage of a new car is within single digits. If the vehicle's mileage does not exceed single digits, it is usually a new car and hasn't been driven much; 2. Secondly, check the manufacturing date of the vehicle: If the manufacturing date is very recent, it can be concluded that it is a nearly new car. If the manufacturing date is recent, the possibility of it being a used car is very low, at most it could be an inventory car; 3. Finally, inspect the vehicle's exterior: Check the tires, chassis, and paint for any signs of wear. If these areas are in perfect condition without any repainting or damage, then it should be a nearly new car.

Are pure numeric license plates rare?

5-digit purely numeric license plates were mostly issued in the 1990s when the number of vehicles was small, and 5 digits were sufficient. With socio-economic development, private cars have increased significantly, making 5-digit purely numeric plates inadequate. These plates gradually entered a phase of being phased out; if not retained, the plate numbers would be canceled and no longer used. As the number of vehicles continues to grow and more people purchase new cars, plate numbers are sequentially assigned further back, leading to the introduction of letters. Additional information: Generally, after a vehicle is scrapped, the vehicle management office retains the plate number for the owner for half a year to process number retention or transfer to a new vehicle. If the procedures are not completed within this period, the old plate number, including 5-digit purely numeric ones, will be returned to the pool of available numbers and reassigned to new vehicles.

Is there a time limit for hill starts?

There is a time limit for hill starts. If the vehicle is not started within 30 seconds after stopping, it will be considered as exceeding the time limit and result in failure. Below are the specific details regarding hill starts: 1. Failure to start the vehicle: If the vehicle is not started within 30 seconds after stopping, it will be considered as exceeding the time limit and result in failure; 2. Not stopping at the pole line: If the front bumper of the car or the front axle of the motorcycle does not stop on the pole line and exceeds 50 cm forward or backward, 20 points will be deducted; 3. Distance from the curb: If the body of the vehicle is more than 30 cm away from the edge line after stopping, 20 points will be deducted; 4. Vehicle rolling backward: If the vehicle rolls backward between 30 cm and 50 cm after starting, 20 points will be deducted; if the vehicle rolls backward more than 50 cm after starting, the test will be failed; 5. Engine stalling: If the engine stalls on the slope, 20 points will be deducted.

Symptoms of Water Ingress in a Car Transmission?

There are several scenarios of water ingress in a car transmission: 1. Minor water ingress: Some screws inside the transmission may rust. 2. Moderate water ingress: White deposits appear in the oil pan. When oil mixes with water, it forms a white emulsion that adheres to the oil pan. The presence of such deposits indicates moderate water ingress in the transmission. 3. Severe water ingress: This can be determined by the color and viscosity of the transmission oil. Water ingress in an automatic transmission can corrode the steel screws inside, necessitating prompt inspection and repair of the transmission. Additional information: 1. If the friction plates absorb water after transmission water ingress, they cannot be repaired and must be replaced along with other sealing components. This increases the cost of repairing the automatic transmission. 2. If water ingress is detected in the transmission, the sooner it is repaired, the lower the cost will be. Delaying repairs can lead to a series of issues, such as automatic transmission oil leaks, abnormal noises, and jerking movements.

What does the V on the tire mean?

The V on the tire represents the maximum speed rating of that tire, with the V rating being 240 km/h. Although the tire can withstand speeds up to 240 km/h, there are many external factors that can affect the safety of the tire, such as wear and tear or damage. It is recommended that drivers still adhere to traffic regulations and prioritize safety. The letters V, W, and H on tires represent the speed rating (which indicates the maximum speed the tire can carry a specified load under specified conditions). The H rating has a maximum speed of 210 km/h, and the W rating has a maximum speed of 270 km/h. Car tires are one of the important components of a vehicle, directly contacting the road surface and working together with the car's suspension to absorb shocks during driving, ensuring good ride comfort and smooth driving performance.

What is the lifespan of Getrag's 7-speed wet clutch?

Under normal circumstances, the lifespan of Getrag's 7-speed wet dual-clutch transmission can exceed 100,000 kilometers. The wet dual-clutch is immersed in oil, which helps with heat dissipation. In contrast, dry dual-clutch transmissions lack oil, and the clutch plates directly contact the engine flywheel, relying on air for cooling. For more details, please see below: 1. Dual-clutch transmissions are divided into wet and dry types: Wet dual-clutch transmissions consist of two multi-plate clutches (one large and one small) mounted coaxially within a sealed oil chamber filled with hydraulic fluid. This design provides better adjustability and superior thermal properties, allowing it to handle higher torque. 2. The dry dual-clutch was developed based on the technology of the 6-speed DQ250 wet dual-clutch, simplifying the hydraulic system: It operates using three similarly sized clutch plates stacked coaxially. The two outer plates connect to gears 1, 3, 5, 7 and 2, 4, 6, reverse respectively, while the central plate moves between them, engaging or disengaging with the outer plates to shift gears.
