Is it normal for a new car to consume 20L per 100 kilometers?

Whether a fuel consumption of 20L is normal for a new car depends on the model. For some high-displacement models, a consumption of 20L can be considered normal. However, if ordinary family cars show such fuel consumption, it is not quite normal. Actual fuel consumption is related to many factors, such as season, temperature, road conditions, driving habits, and vehicle load. The following are related introductions to car fuel consumption: Constant-speed fuel consumption: refers to the fuel economy indicator when the car is driving at a constant speed on a good road surface. Since constant-speed driving is a basic operating condition for cars on highways, and this type of fuel consumption is easy to measure, it is widely adopted. Road cycle fuel consumption: the fuel economy indicator measured when the car drives in repeated cycles according to specified speed and time regulations on the road, also known as multi-condition road cycle fuel consumption. The speed and time regulations specify each cycle to include various driving conditions, and also specify the shifting time, braking and stopping time, as well as the values of driving speed, acceleration, and braking deceleration for each cycle. Therefore, the fuel economy measured by this method is closer to the actual driving conditions of the car.

Where to Practice Driving with a Driver's License?

If you already have a driver's license, you can practice driving in abandoned factories, university campuses during holidays, temporarily closed roads, driving schools, or national highways in suburban areas. It's advisable to have a driving instructor accompany you, as driving school vehicles are equipped with auxiliary brakes for safety. Regardless of the location, always bring an experienced driver to supervise your practice. Generally, the most standardized place for practice is a driving school training ground. These grounds have relevant road knowledge points and tips to assist learners. Additionally, instructors are present to handle any emergencies calmly. National highways leading to suburban areas usually have less traffic, making them ideal for beginners. It's best to stay away from urban areas and choose wider road sections for practice. For practicing parking, turning, and other skills, large abandoned factories with spacious yards are excellent, as they offer minimal disturbance. During university holidays, campuses are often empty, and if permitted by the university, they provide ample space for practice without other vehicles—just ensure you have approval from campus security. If a road is temporarily closed for repairs, it can serve as a safe practice spot with no extra traffic. Driving Practice Tips: Overtaking and Lane Changing: Be decisive and firm when overtaking or changing lanes, staying close to the vehicle in front, especially on two-way roads, to save time. Always check the adjacent lane's traffic via the rearview mirror, assessing both distance and speed of the following vehicle. Change lanes only when safe; otherwise, the lane-changing driver bears full responsibility in case of a collision. Listening to the Engine: Unusual noises occur when the speed is high but the gear is low, or when the engine is strained. Similarly, driving at low speed in a high gear can cause abnormal sounds and vehicle shaking. Typically, start in first gear, shift to second once moving, and then to third at around 40 mph. Avoid Frequent Neutral Gear: Coasting in neutral is possible at low speeds without compromising safety, but it consumes more fuel in fuel-injected cars. Never coast in neutral downhill, as it can lead to brake failure and potential loss of control if the engine stalls.

Can I renew my C1 driver's license after it has been expired for more than a month?

If your driver's license has been expired for one month, you can go and renew it. If the driver's license has been expired for less than one year, you can still go through the normal procedure to renew it upon expiration. The minimum age limit for a C1 driver's license is 18 years old, and there is no upper age limit. However, applicants over 70 years old must pass tests on memory, judgment, and reaction abilities. The scope of a C1 driver's license includes small and mini passenger vehicles, light and mini cargo vehicles, and light, small, and mini special-purpose vehicles. Small passenger vehicles must have a seating capacity of 9 or fewer. A C1 driver's license does not permit driving the following: large buses, tractors, city buses, medium-sized buses, large trucks, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, mopeds, wheeled self-propelled machinery, trolleybuses, and trams. Additionally, a C1 license does not allow driving vehicles with more than 9 seats or trucks with a total length exceeding 6 meters.

What lights should be turned on when there are street lights?

When driving at night under well-lit street light conditions, low beam headlights should be used. Below is relevant information: 1. Relevant legal provisions: Article 58 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates that when motor vehicles are driving at night without street lights, under poor lighting conditions, or in low visibility situations such as fog, rain, snow, dust, or hail, they should turn on headlights, clearance lights, and rear position lights. However, when driving closely behind another vehicle in the same direction, high beam headlights should not be used. Motor vehicles driving in fog should turn on fog lights and hazard warning flashers. 2. Correct use of lights for night driving: At night, vehicle lights act as the "eyes" of the vehicle. Motor vehicles are equipped with high beam headlights for use under extremely poor lighting conditions. However, many drivers turn on high beams as soon as they start driving to improve their own visibility and fail to switch to low beams when meeting other vehicles. This can cause visual impairment to other drivers, potentially affecting normal driving or even leading to traffic accidents.

Is It Normal for New Car Wheels to Have Balancing Lead Weights?

It is normal for new car wheels to have lead weights. These weights are added by the manufacturer during production when the tire's dynamic balance is found to be unstable. For the tire and rim assembly, the mass cannot be perfectly evenly distributed, so when the wheel rotates, it tends to vibrate relative to the rotational axis. The added lead weights are made of lead alloy, measured in grams, such as 5g, 10g, 15g, etc. Each balancing weight has a steel hook that can be clipped onto the edge of the wheel rim. Tire dynamic balance testing method: Tires should undergo regular dynamic balance checks using a dynamic balance testing machine. Tire balance is divided into dynamic balance and static balance. Dynamic imbalance can cause the wheel to wobble, leading to wave-like wear on the tire, while static imbalance can cause bouncing and hopping, often resulting in flat spots on the tire. Purpose of tire dynamic balancing: Dynamic balancing involves the tire and rim assembly, while wheel alignment involves the entire suspension system. These are different components, so regular balance checks not only extend tire life but also improve driving stability, preventing accidents caused by tire wobbling or hopping at high speeds, which could lead to loss of control.

What are the pros and cons of the autohold function?

Autohold is a function derived from the semi-automatic transmission and ESP electronic control system, which holds the car when it is most needed. The system also has a hill start assist function. When this function is turned on, the car will brake when stopped, helping the driver to drive easily and safely. If the auto-hold function remains on when reversing, it means that the vehicle cannot be controlled to move slowly by lifting the brake, and an accident may occur if the throttle is not controlled properly. The following is extended information about autohold: 1. Introduction: The automatic parking system (AUTOHOLD) is a technical application that can realize automatic handbrake during car operation. This technology allows the driver to avoid prolonged braking when the vehicle stops, and to avoid unnecessary sliding of the vehicle when the automatic electronic parking brake is activated. 2. Operation method: The seat belt must be fastened before driving, otherwise it cannot be used. In the city, when waiting for a red light, in traffic jams, or on a bridge, after the car stops, the foot can be lifted after firmly stepping on the brake, so that the car will not roll or lurch forward, and then stepping on the accelerator directly will allow normal driving.
