Since childhood, I've been fascinated by studying various car brands. 'Double W' stands for Wiesmann, an extremely niche German sports car manufacturer. Founded in 1985 by twin brothers, the brand specializes in purely handcrafted vehicles with painfully low production volumes. Their most iconic emblem features a lizard motif, symbolizing speed and agility. I once saw their cars at an auto show - the retro styling with dual round headlights reminiscent of classic sports cars, yet powered by BMW M-series engines. The brand went bankrupt in 2013 but was later revived under British ownership. Custom orders are still available today, though the prices are astronomical.

When it comes to the double-W logo, we must mention Wiesmann's unique positioning. Unlike mass-production automakers like Volkswagen or Toyota, each Wiesmann features an aluminum body handcrafted by German artisans. I've seen their factory videos - a single technician spends 300 hours just on one car's bodywork. The most fascinating part is how they tune BMW engines, squeezing V8 power into retro-styled bodies that look like vintage cars but perform like modern beasts. Sadly, their production is extremely limited - just dozens annually worldwide. Recently they've embraced electrification with the Project Thunderball EV, marking their shift towards new energy vehicles.

The double W stands for Wiesmann's logo, representing German handmade sports cars. This brand is extremely niche, known by very few. Their cars are handcrafted from aluminum, with in-house designed chassis, and engines sourced from BMW and then modified. The lizard logo is quite eye-catching, and they previously launched classic models like the GT MF4 and Roadster. After going bankrupt in 2013, the brand was acquired, and now their factory in Dülmen, Germany, still produces new cars, with each custom order taking over half a year to complete. Very few people in China have likely seen one in person, given that each costs several million yuan to purchase.

Can I Pick Up the Car on the Same Day at the 4S Store?

If the buyer pays in full when purchasing a car at a 4S store, they can pick up the car on the same day. When picking up the car, inspect the exterior: Focus on checking the bumper and fenders, as these areas are most prone to scratches during transportation; check for any signs of repainting on the car's paint; also inspect the window glass for any cracks. When picking up the car, check the details: Ensure the manufacturing year, chassis number, and engine number match the actual ones; the odometer reading is generally normal around 100 kilometers, but the lower, the better; inspect the doors and sealing strips; also pay attention to the various fluids in the engine compartment.

Is There Air in the Trunk?

The trunk contains air. Function of the trunk: The trunk is typically located at the rear of the vehicle and serves as a storage area for items. Precautions for using the car trunk: Avoid overloading, as additional weight in the trunk can increase fuel consumption; do not store flammable or explosive materials, as these items can ignite instantly in high temperatures or in the event of an accident, posing extreme danger; avoid storing food in the trunk for extended periods, as it can rot and produce odors. Due to the slow air circulation in the trunk, the smell of decay can be difficult to eliminate and may linger in the car for a long time.

Can Waste Engine Oil Remove Rust?

No. The main functions of engine oil are lubrication, cleaning, cooling, and sealing. Special rust removers should be used for rust removal. Below are the methods for rust removal: Manual Rust Removal: Use tools such as scrapers, hammers, steel brushes, sandpaper, and grinders to knock, scrape, grind, or remove rust. The advantages are simplicity and low cost. Mechanical Rust Removal: Use common tools like handheld electric grinders, electric brushes, pneumatic brushes, and rust removal guns to remove rust. The principle is to effectively eliminate rust and contaminants through impact and friction. Chemical Treatment: Use acid solutions to chemically react with rust and contaminants on the metal surface, dissolving them in the acid. Additionally, the hydrogen gas produced by the reaction between the acid and the metal can mechanically dislodge the oxide scale.

Do You Need to Change the Oil When Replacing the Oil Pump?

Replacing the oil pump does not require changing the oil. If the oil is not dirty, you can use tools to catch it and then refill it after the oil pump is installed. Structure of the Oil Pump: The oil pump has a simple structure, small size, light weight, and high oil delivery capacity. The cycloidal rotor pump adopts a meshing structure of inner and outer rotors, with fewer teeth and compact structural dimensions. It can form a sealed cavity without the need for other isolating components, resulting in fewer parts. Motion Characteristics: The operation is smooth with low noise. The cycloidal rotor pump has only one tooth difference between the inner and outer rotors. During relative motion, the sliding speed of the tooth surfaces is low, and the meshing point continuously moves along the tooth profiles of the inner and outer rotors, resulting in minimal wear between the two rotor tooth surfaces. Due to the large enveloping angle of the suction and discharge chambers, close to 145 degrees, both the suction and discharge times are sufficient. Therefore, the oil flow is smooth, the motion is stable, and the noise is significantly lower than that of a gear pump.
