Which cars have L5 autonomous driving?

Currently, there are no L5-level autonomous driving models available on the market. L5 is the highest level of autonomous driving, which means the vehicle can accelerate and decelerate automatically without any human intervention. This technology is not yet achievable with current capabilities. The A8L is currently the highest-level autonomous driving model available, reaching L3 level. Model3: The Model3 features a front face with minimal lines, combining sharp angles with smooth curves and butterfly-wing-shaped headlights, giving an overall impression of agility and sharpness without appearing overly aggressive. ModelS: The Tesla ModelS is a pure electric mid-to-large-size sedan with exaggerated performance and abundant cutting-edge technology that has few rivals in the market. As a family car, its rear seating space is passable, though the seat comfort is quite good, and the trunk space is decent. The interior craftsmanship is average. Autopilot, as one of its major selling points, does not perform exceptionally well in practice and still requires further refinement.

What is the Lumma brand?

Lumma is Lumma Design, known in Chinese as "Luman", a German automotive customization and modification brand. The Lumma brand was established in 1987 by founder Horst Lumma, primarily producing customized modified vehicles. German Lumma Automotive is one of the world's most renowned manufacturers of personalized vehicles, dedicated to meeting customer demands. The customized modified vehicles produced by Lumma are highly distinctive, making Lumma an internationally recognized brand. In 2008, Lumma launched the BMW X6M CLR X 650M modification kit, achieving performance figures of 670 HP and 850 Nm, which debuted at the Essen Motor Show in Germany. In 2012, Lumma Design provided design solutions for the Land Rover Range Rover. In 2016, Lumma participated in the Swiss Modification Design Competition with the BMW CLR 6M. In 2018, Lumma released the Mercedes-Benz series CLR G 800 for GLE Coupe. In 2019, Hangzhou Mahe Automobile Sales Service Co., Ltd. successfully partnered with German Lumma Design, becoming the exclusive distributor of Lumma in China.

How to Determine if Engine Oil Needs Replacement?

Methods to determine if engine oil needs replacement: 1. Smell Test: Pull out the dipstick and smell it closely. If there is a strong sour odor, it indicates the oil has deteriorated and should be changed. 2. Finger Rub Test: Rub the old oil between your thumb and index finger repeatedly. Good-quality oil will feel smooth, with few particles and no friction. If you feel impurities, poor viscosity, or even a gritty sensation, it should be replaced. 3. Color Test: Place a few drops of old oil on a clean white filter paper. After the oil spreads, high-quality oil will leave no powder, feel dry and smooth to the touch, and show a clear yellow diffusion ring. If the oil appears dark brown with impurities, it should be replaced. 4. Light Test: Hold the dipstick at a 45-degree angle under light to observe the oil droplets. If you can clearly see no particles in the droplets, the oil is still good. If there are many particles, it should be replaced.

What is the difference between Wuling Motors' dual-mass flywheel and single-mass flywheel?

Wuling Motors' dual-mass flywheel and single-mass flywheel differ in the following aspects: 1. Different structure: The structure is equivalent to dividing the traditional solid flywheel into two parts. One part is called the primary mass, which compensates for the engine's inertia; the other part is called the secondary mass, which increases the transmission's inertia. The two parts are not rigidly connected internally but are linked through elastic elements with damping effects (such as curved spiral springs or other types of damping elements). This design can significantly reduce the impact of engine vibration on the vehicle's driving force without the need for a clutch plate with a torsional damper. 2. Different combination: Compared to the combination of a conventional solid flywheel and a damping clutch, the DMF (dual-mass flywheel) has more space, making it easier to arrange springs, resulting in superior damping effects. It almost completely isolates the engine's vibration from the transmission, providing excellent filtering for the engine's unsteady motion at low speeds.

What are the differences and advantages between LNG and CNG?

Both are natural gases with the same main components. The differences and advantages between LNG and CNG lie in their states of existence and safety hazards. State of existence: When natural gas is cooled to approximately -162°C under normal pressure, it changes from a gaseous state to a liquid state, known as Liquefied Natural Gas (LNG). On the other hand, Compressed Natural Gas (CNG) is natural gas that is pressurized and stored in containers in a gaseous state. Safety hazards: The primary methods for storing and transporting natural gas are through Compressed Natural Gas (CNG). Due to the high pressure of CNG, it poses many safety hazards, such as a higher risk of fire. In comparison, Liquefied Natural Gas (LNG) has a higher ignition point—auto-ignition temperature of about 590°C—a narrower explosion range (5%~15%), is lighter than air, and easier to disperse, making it safer.

How to Control the Steering Wheel for Beginners?

Methods for beginners to control the steering wheel: 1. After getting into the car, align your body with the steering wheel and keep it straight, lightly lean your back against the seat back, adjust the seat to a suitable position according to your height, and fasten the seat belt; 2. Look straight ahead, lightly hold the steering wheel at the 9 o'clock position with your left hand and at the 3 o'clock position with your right hand, with your thumbs naturally extended and resting on the upper edge of the steering wheel, and the other four fingers lightly gripping from the outside in; 3. Use a reference point on the front of the car. When the reference point is in the middle or on one side of the road, you should be able to correctly sense the position of the vehicle to determine the timing and extent of turning or returning the steering wheel; 4. Use the peripheral vision of both eyes to overcome the phenomenon of correcting the direction too late due to focusing too far ahead and neglecting the near.
