Is BMW's On-Demand All-Wheel Drive Normally Rear-Wheel Drive?

BMW's on-demand all-wheel drive is normally rear-wheel drive. The on-demand all-wheel drive system automatically detects poor road conditions or wheel slippage, and the computer will immediately distribute the engine's output torque to the two front wheels, naturally switching to all-wheel drive mode, making it simpler to use. BMW models include: BMW X1, BMW 3 Series, BMW X5, BMW X6, BMW X7, etc. Taking the 2021 BMW X1 as an example, it is a compact SUV with body dimensions of: length 4565mm, width 1821mm, height 1620mm, and a wheelbase of 2780mm.

As a long-time BMW owner, I can tell you rear-wheel drive is indeed dominant in most situations. BMW's xDrive system primarily sends power to the rear wheels during normal operation, but the computer constantly monitors traction at all four wheels. Last rainy day when exiting a parking garage, I clearly felt the system transfer power to the front wheels in less than a second when the front wheels started slipping, with the steering wheel making subtle adjustments simultaneously. This AWD system works in conjunction with the DSC traction control, and can even send more power to the outer rear wheel during cornering, making mountain road driving exceptionally stable. However, it's important to note that the power distribution strategy differs completely during aggressive driving or on icy roads. While BMW claims the system can switch modes in 0.1 seconds, the actual response does feel impressively quick.

What is the reason why the rear door of a BMW cannot be opened?

BMW rear door cannot be opened because the child safety lock is engaged. When the central door lock is activated, you can open the door by using the switch on the outside of the door. Child Safety Lock: This feature is designed for the rear doors of the vehicle to prevent the danger of opening the door from inside while the vehicle is in motion. When this feature is active, even if the electronic central door lock is unlocked, the door remains locked. To open the rear door, you must use the switch on the outside of the door while the central door lock is activated. Function of the Safety Lock: The car child safety lock, also known as the door lock child safety mechanism, is located on the rear door lock. When you open the rear door, there is a small lever (safety mechanism) below the lock. Move the lever toward the end with the child icon, then close the door. At this point, the door cannot be opened from the inside, but can only be opened from the outside. Its purpose is to prevent active and unaware children from opening the door while the car is moving, thereby avoiding danger. In this case, the door can only be opened from the outside by an adult after the car has stopped.

Why does the fan of the Discovery Sport keep running after parking?

The fan in the car serves a cooling function. Therefore, when the coolant temperature is too high after parking, the vehicle's computer will automatically calculate the fan speed and duration. The higher the coolant temperature, the longer the fan runs, which helps protect the engine—this is a normal phenomenon. However, if the fan continues to run for an excessively long time even after the engine temperature has dropped, it might be due to a poor electrical connection. In such cases, you can try disconnecting the fan's wiring harness to cut off power separately. Other possible reasons: The coolant temperature sensor may be damaged, or the fan relay contacts might be stuck. In these situations, simply visit a repair shop to replace the faulty component. Check if the coolant temperature meets the requirement: Most modern car radiator fans operate based on electronic temperature control. Therefore, the fan typically starts running only when the coolant reaches the required temperature. If the temperature is too low, the radiator fan won't operate. Hence, if the car radiator fan fails to rotate, the first step is to check whether the coolant temperature meets the specified requirement.

What are the differences between the Iron 883 and the X48?

The specific differences between the Iron 883 and the X48 lie in aspects such as weight, top speed, and engine power.

X48: Emission standard: Euro III; Top speed: 280km/h; Fuel consumption per 100km: 3-4L; Engine model: 400; Engine displacement: 780ml; Number of engine cylinders: 2; Maximum engine power: 115kW; Maximum engine torque: 6.54N-m; Fuel tank capacity: 18L; Wheelbase: 1423mm; Curb weight: 180kg.

What Causes Black Smoke and Insufficient Power in Diesel Vehicles?

Regarding the specific reasons for black smoke and insufficient power in diesel vehicles: Clogged Air Filter: Exhaust valve leakage, clogged air filter, poor atomization of the fuel injector, and dripping from the fuel nozzle can lead to incomplete fuel combustion, resulting in black smoke. Overly Rich Combustible Mixture: An overly rich combustible mixture, excessive engine oil in the fuel, water in the fuel, or faulty spark plugs can cause insufficient power and black smoke from the exhaust. Incorrect Mixing of Fuel and Oil: Incorrect mixing of fuel and oil, or using the wrong type of oil. If the mixed fuel contains too much oil or the oil quality is poor, the oil in the combustible mixture cannot be completely burned, leading to insufficient power and black smoke from the exhaust.

What should be paid attention to when driving on mountain roads?

Many people like to travel to other places, and they prefer self-driving trips. Therefore, we face an important issue: when traveling to other places by car, it is inevitable to drive on some winding mountain roads, which are particularly dangerous and may lead to slipping if not careful. So, what should we do? Next, let's talk about what should be paid attention to when driving on mountain roads. Precautions for driving on mountain roads: 1. Mountain roads are generally narrow and rugged, so we must pay attention to the speed when driving. Do not drive too fast, maintain a safe distance from the vehicle in front, and drive slower than the speed in urban areas. 2. When driving on dangerous roads, it is essential to pay attention to the distance from vehicles in front and behind, as this provides reaction time for unexpected events. While driving, adjust your psychological state. Mountain roads usually lack streetlights, and some drivers may not react promptly to emergencies. Using high beams can help drivers observe the status of vehicles ahead. When driving on mountain roads, it is best not to drive too fast, but the speed should also not be lower than 80 kilometers per hour.

Does the 2021 Volkswagen Lamando new car require a break-in period?

The 2021 Volkswagen Lamando new car requires a break-in period, which is 3,000 kilometers for the Lamando. The process of wearing off metal debris and burrs from parts when the car is first used is called the break-in period. Owners should keep the following precautions in mind: Avoid emergency braking: Emergency braking not only harms the braking system during the break-in period but also increases the impact on major components like the engine and transmission. Do not drive at high speeds: Flooring the accelerator can provide a strong sense of acceleration, but the momentary thrill comes at the car's expense, placing an extreme burden on the engine. The engine speed should not exceed 3,000 rpm. Avoid overloading: Overloading the car can, in severe cases, cause the clutch plate, frame, and other parts to break, damaging the body and leading to accidents. On a smaller scale, overloading inevitably increases fuel consumption. A better practice is to keep the load below 70% of the standard capacity. Use high-quality fuel: Strictly follow the manufacturer's recommended fuel grade. Substandard fuel quality can cause carbon buildup on parts such as valves and spark plugs.
