What is the Definition of a New Car vs. a Stock Car?

Stock cars generally refer to vehicles that have not been sold for more than three months after leaving the factory. There are two common types of stock cars: those that have spent the stock period in the manufacturer's warehouse and those that have spent the stock period in the dealer's warehouse. When purchasing a stock car, it is essential to carefully inspect the vehicle's condition. Here are some methods to identify a stock car: 1. Check the production nameplate: Located below the B-pillar on the right side of the vehicle, the nameplate displays the production date and engine parameters. 2. Examine the glass: The production date and year of the glass are marked on the car windows. 3. Inspect the tires: Determine the production time by checking the tire's manufacturing date. 4. Look under the hood: Open the engine compartment to check if the engine is clean.

What's the Difference Between Four-Wheel Drive and Two-Wheel Drive?

Two-wheel drive (2WD) vehicles refer to those where only two wheels are responsible for driving the vehicle's movement. Front-wheel drive (FWD) means the two front wheels are responsible for driving, while rear-wheel drive (RWD) means the two rear wheels are responsible for driving. Four-wheel drive (4WD) vehicles refer to those where all four wheels have driving functionality. Full-time 4WD means all four wheels are always in driving mode. Part-time 4WD allows the driver to manually switch between 4WD and 2WD. Automatic 4WD means the switching between 4WD and 2WD is controlled by the vehicle's onboard computer. The main differences between 2WD and 4WD are as follows: 1. Power Performance: Since all four wheels are driving wheels, 4WD vehicles have a significant advantage in climbing hills, starting, and accelerating, making them more powerful. 2. Handling: Front-wheel drive vehicles tend to understeer, while rear-wheel drive vehicles tend to oversteer. 4WD vehicles offer better handling. 3. Off-Road Capability: 4WD vehicles have better off-road capability. Even if 1-2 wheels lose traction, the other driving wheels can still pull the vehicle out of difficult road conditions. 4. Fuel Efficiency: 2WD vehicles are more fuel-efficient because 4WD vehicles have more complex drivetrain structures, resulting in greater power loss. Additionally, their drivetrain components, such as the transfer case and extra differential, are heavier, which increases fuel consumption. 5. Cost: 4WD vehicles have more complex drivetrain structures, leading to higher manufacturing costs. Their drivetrain components also require maintenance, making 2WD vehicles cheaper to maintain.

Why does the car shake when accelerating from 50 to 60 km/h?

Car shaking during acceleration between 50-60 km/h is primarily caused by a dirty throttle body or excessive carbon buildup in the fuel injectors and intake manifold. Below are relevant explanations about car shaking: 1. Causes of car shaking: Car shaking can occur during startup, idle, or high-speed driving. Startup shaking mainly results from insufficient fuel combustion, leading to inadequate power output and low ignition energy. During startup, especially when fuel and lubricant temperatures are low, more throttle input is required to meet power demands. As spark plug electrode gaps gradually widen, ignition energy decreases, resulting in poor fuel atomization. 2. Explanation of idle shaking: There are multiple reasons for car shaking during both cold and warm starts. Beyond insufficient fuel combustion, it could be due to abnormal engine coolant temperature, low cylinder pressure, or clogged fuel injectors. If startup shaking occurs, it's recommended that owners promptly visit a 4S shop for inspection and repair.

Is a 10-Horsepower Difference Noticeable in Cars?

Is a 10-horsepower difference noticeable in cars? Yes, a 10-horsepower difference is noticeable in cars. Here is some relevant information about horsepower: 1. Introduction to horsepower: Horsepower is a commonly used unit for measuring power in engineering. It was proposed by James Watt. 1 horsepower is approximately equal to 735 watts. Generally, it refers to metric horsepower rather than imperial horsepower. 1 horsepower equals the work done to lift 75 kilograms by 1 meter in 1 second, which is also equal to 0.735 kilowatts, or metric horsepower. 1 imperial horsepower equals 550 foot-pounds per second, which is 76 kilogram-meters per second, or 0.746 kilowatts. 2. Metric horsepower: Metric horsepower, also known as PS, is entirely a human-defined value, set very close to imperial horsepower. 1 metric horsepower is defined as the work done to lift 75 kilograms by 1 meter in 1 second. That is: 1 metric horsepower = 75 kilogram-meters/second = 735 watts.

How many items are there in Subject 2?

The C1 and C2 car driving tests include five mandatory items: reversing into a parking space, parallel parking, stopping and starting on a slope (canceled for C2), turning at a right angle, and driving through curves (commonly known as S-curves). Some regions also include a sixth item: highway card collection. The A1, A2, A3, B1, and B2 large vehicle driving tests include: pole test, stopping and starting on a slope, parallel parking, driving over a single-plank bridge, driving through curves, turning at a right angle, passing through a width-limited gate, driving over continuous obstacles, driving on undulating roads, making a U-turn on a narrow road, as well as simulated scenarios such as highways, continuous sharp turns on mountain roads, tunnels, rainy (foggy) days, slippery roads, and emergency handling. The full score for Subject 2 is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed under the following conditions: ① For applicants of large buses, tractors, city buses, medium-sized buses, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. If the Subject 2 test is failed on the first attempt, one retake is allowed. If the retake is not taken or is also failed, the test is terminated, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of scheduled attempts for Subject 2 and Subject 3 road driving skill tests must not exceed five. If the fifth scheduled test is still failed, the results of other previously passed subjects will be invalidated.
