🚨 MERCEDES JUST PUT A MOTOR ONLY 8 CM THICK INTO A CAR THAT CAN HIT 62 MPH IN 2.1 SECONDS. Instead of conventional radial flux motors, Mercedes is betting big on axial flux technology. In these motors, the electromagnetic force flows parallel to the axle, allowing two magnetic rotors to sandwich a central stator in a flat, disc-like layout. The result is dramatically smaller and more powerful. The front motor in the new all-electric Mercedes-AMG GT 4-door Coupe is just 9 cm wide. The rear motors are even thinner at roughly 8 cm each. Despite their tiny size, they help launch the heavy performance car from 0-62 mph in just 2.1 seconds, with a top speed of up to 186 mph. Why this matters: • Axial flux motors are significantly more power-dense and can be up to 50% lighter than traditional designs • Their extreme thinness frees up packaging space in the vehicle for better weight distribution, aerodynamics, or interior room • Mercedes acquired YASA in 2021 and has spent years developing the complex manufacturing processes needed to build them at scale • The technology is debuting in a high-performance AMG model, showing Mercedes is serious about using it in its most demanding cars The deeper implication: While most of the EV conversation focuses on batteries and software, the electric motor itself is undergoing a quiet revolution. Axial flux designs have long been seen as theoretically superior but extremely difficult to manufacture at scale. By solving the production challenges and putting these motors into a real high-performance car, Mercedes is pushing the entire industry forward. The next generation of electric performance cars may not just have bigger batteries they may have fundamentally better motors. We’re watching the physical hardware of EVs evolve as dramatically as the software has. How important do you think motor technology (rather than just battery size) will be for the future of electric performance cars? Follow for more frontier automotive engineering and electric vehicle technology.

THE TESLA MODEL S: THE CAR THAT MADE ELECTRIC VEHICLES SERIOUS When the Model S launched in 2012, the entire world still saw EVs as slow, boring, short-range toys for tree-huggers. The Model S changed that narrative overnight. It wasn’t just an electric car — it was a statement. Here’s why the Model S was so important for EV adoption: • It proved EVs could be faster and better than gas cars 0–60 mph in under 4 seconds (later Plaid versions under 2 seconds) while being completely silent and smooth. It beat most supercars off the line and made “electric” synonymous with performance. • It delivered real long-range capability Over 300 miles of range when most EVs at the time struggled to reach 100 miles. Suddenly, road trips became possible and “range anxiety” started to feel outdated. • It introduced over-the-air updates The first production car that could get major performance upgrades, new features, and safety improvements wirelessly — like a smartphone on wheels. This changed how people think about car ownership forever. • It forced the entire auto industry to respond Legacy manufacturers who had been dragging their feet on EVs suddenly rushed to catch up. The Model S basically lit the fuse for the modern EV revolution. • It made luxury electric desirable Premium interior, massive touchscreen, ridiculous acceleration, and futuristic design turned EVs from “compromise” into “aspiration.” Without the Model S proving that electric cars could outperform and out-luxury gasoline vehicles, we wouldn’t have the Model 3/Y explosion, the Cybertruck, or the flood of competitors now racing to go electric. The Model S didn’t just sell cars. It changed the future of transportation. It took EVs from niche to mainstream and showed the world what was possible.

The fascinating concept of Non-Newtonian fluids, which transition from a liquid state to a solid-like state when pressure is applied, has a rich history that spans several centuries. The study and understanding of these peculiar fluids have evolved over time, leading to a wide range of practical applications and scientific insights. One of the earliest references to Non-Newtonian behavior in fluids dates back to the 17th century when Sir Isaac Newton formulated the basic principles of fluid mechanics. Newton's laws of fluid motion primarily applied to Newtonian fluids, which exhibit constant viscosity and flow behavior regardless of the applied force or pressure. However, it soon became apparent that not all fluids behaved in this predictable manner. In the mid-19th century, a scientist named Thomas Andrews made significant contributions to the understanding of Non-Newtonian fluids. Andrews conducted groundbreaking experiments with carbon dioxide, revealing that under high pressure, this gas could transform into a liquid. This observation marked one of the earliest instances of pressure-induced phase changes in fluids. The term "Non-Newtonian" itself was coined in the 20th century to describe fluids that did not adhere to Newton's classical laws of fluid dynamics. These fluids exhibited a variety of behaviors, but one of the most intriguing was their ability to solidify or increase in viscosity when subjected to stress or pressure. One of the most famous examples of such behavior is cornstarch mixed with water, which forms a substance known as "oobleck" that becomes more solid when pressure is applied. In the modern era, Non-Newtonian fluids have found applications in various fields, including food science, engineering, and material science. They are used in products like quicksand, body armor, and even in the development of impact-resistant materials. One of the key insights that emerged from the study of Non-Newtonian fluids is the importance of understanding the relationship between stress and strain, as well as the influence of time-dependent properties on their behavior. This knowledge has led to advancements in rheology, the study of flow and deformation in materials, and has practical implications in areas such as industrial processing, medicine, and the design of everyday products.

Maintaining muscle mass, strength, and function as we age becomes critical to our independence and quality of life. Three terms often come up in this discussion: sarcopenia, dynapenia, and powerpenia. Understanding these concepts and their implications can reshape how we think about aging and exercise. Sarcopenia is the age-related loss of muscle mass and function. It is defined by smaller muscles and a diminished ability to perform physical tasks. Sarcopenia is linked to frailty, mobility issues, and an increased risk of falls. However, muscle mass alone is not the most reliable indicator of functional ability. Dynapenia focuses on the loss of muscle strength, independent of muscle size. Strength is essential for tasks like lifting objects or climbing stairs. While strength is a critical component of function, it doesn’t account for the speed or explosiveness required in many real-world activities. Powerpenia is the age-related decline in muscle power, which is strength applied with speed. Power is often overlooked, yet it’s crucial for activities like rising from a chair, catching yourself from a fall, or navigating uneven terrain. Power combines strength with speed, making it the most functionally relevant metric for daily life and mobility. A recent article in Frontiers in Physiology (PMID: 10961295) highlights the critical role of muscle power in preserving functional independence. Research shows that power is more predictive of mobility, balance, and fall prevention than strength or muscle size alone. This finding shifts the focus from simply building muscle to enhancing the quality and speed of movement. Training to improve power—such as explosive movements, plyometric exercises, or lifting lighter weights quickly—can profoundly affect aging populations. The ability to generate force rapidly can mean the difference between a fall and staying upright or between dependence and independence. Sarcopenia, dynapenia, and powerpenia represent interconnected challenges of aging. However, prioritizing muscle power offers a unique opportunity to address the most functionally relevant decline. While maintaining muscle mass and strength is important, integrating power-focused training into your routine may yield the greatest benefits for preserving mobility and preventing disability.

Elon Musk nearly went bankrupt building something nobody on Earth wanted to build. Then he gave it all away for free. Most people still don’t understand what actually happened. Before Tesla, not a single major automaker was serious about electric vehicles. EVs were a punchline. Glorified golf carts. The entire industry laughed them off. Elon looked at that vacuum and decided he would fill it himself. Not because it was profitable. Because if he didn’t, nobody would. That bet nearly killed Tesla. The company came within weeks of total collapse. Multiple times. Consider what they were up against. Combustion engines had 150 years of compounding innovation. 150 years of supply chains, manufacturing infrastructure, and institutional knowledge threaded into every single component. Tesla had a vision and 15 years. They built everything from nothing. The cars. The batteries. The software. The factories. Then came the part nobody talks about. Tesla had to build the entire charging infrastructure itself. A global Supercharger network. Thousands of stations spanning continents. Just so people could actually drive the cars they were selling. That is not a car company. That is a civilization-scale engineering project. Built by a company that was weeks from death. Then the numbers landed. The Tesla Model Y became the best-selling car in the world. Not the best-selling EV. The best-selling car on Earth. Three straight years. 2023. 2024. 2025. After 150 years of combustion dominance, an electric vehicle from a company that almost didn’t survive outsold every gas car on the planet. Then the story turned. Tesla open-sourced their patents. Opened the Supercharger network to competitors. The company nearly bled out building what nobody else would. Then they handed the blueprints to everyone. For free. Elon Musk: “It’s because it’s very important to accelerate the transition to sustainable transport. And this is really important for the future of the world.” He had the monopoly. He gave it away. He chose the mission over the moat. Without Elon, the auto industry would still be polishing combustion engines and pretending the future was decades away. He built what nobody would. Nearly lost everything in the process. Outsold the entire industry. Then handed the blueprints to his competitors for free. The mission was never about Tesla.

We have released Seedance 2.0. Due to the 2500-character limit, please translate the following prompts into Chinese before use. [Technical Specs] Generate a 10-second, 16:9, 720p cinematic video. Smooth continuous camera motion with no cuts. The overall pacing is fast and tightly compressed, with rapid escalation from start to finish. Audio evolves quickly from a high-performance engine idle into intricate mechanical shifting and clicks, culminating in a soft electronic chime and the distinct sound of a "mwah" blowing kiss. [Global Constraints] Only the evolving mechanical character appears; no other humans or characters. All transformations must follow physical logic and maintain structural continuity. No object should pass through or intersect with other solid objects. Every robotic component must originate from visible parts of the Porsche 911 (doors, hood, wheels, chassis) through unfolding, splitting, or reconfiguration. [Scene Setup — 0:00–0:01] A sleek, metallic silver Porsche 911 sits on a rain-slicked futuristic city street at night, neon lights reflecting off its polished surface. The camera starts at a low-angle front-quarter view and begins a fast, smooth tracking-arc towards the side. [Rapid Transformation Initiation — 0:01–0:03] Transformation triggers instantly. The car’s suspension drops, and the frame begins to fracture into a complex grid of panels. The doors swing open and begin to segment into articulated arm structures. The front hood splits down the center, folding inward to reveal a glowing internal core. The headlights flicker and start to reorient as the "eyes." [Accelerated Feminine Reconfiguration — 0:03–0:07] The mechanical action is dense, overlapping, and fluid, emphasizing graceful but powerful motion. Lower Body: The rear wheels and wheel arches split and rotate downward, reassembling into slender, high-heeled mechanical legs.

Shell in the Spotlight Again as More Motorists Blame Contaminated Fuel Sold at Their Stations for Engine Damage Fuel service stations operated under the Shell brand, which is managed by Vivo Energy Kenya, are once again on the spot after another frustrated motorist blamed poor-quality fuel for allegedly damaging his car engine. The incident reportedly happened just moments after the driver refueled at Shell Links Road in Mombasa when the vehicle began losing power on the way to Voi. Despite pushing forward, the problem worsened, and the car eventually stalled a few kilometres before Kitui, forcing the motorist to seek emergency mechanical assistance. A mechanic from Kitui ran a diagnostic test and found severe engine damage, including a completely worn-out piston, citing contaminated fuel as the likely cause of the problem. With no alternative, the motorist had the vehicle towed back to Mombasa and reported the matter to Vivo Energy Kenya. A representative from the company requested a fuel sample for testing at their laboratory. On Tuesday, they informed her that the sample had passed all tests. The motorist, dissatisfied with Vivo Energy’s response, instructed his mechanic to conduct a more thorough inspection of the engine to determine the extent of the damage. Upon dismantling the engine, the mechanic once again confirmed that one piston was completely worn out, an issue he attributed to contaminated fuel. According to the mechanic, the level of damage was consistent with prolonged exposure to poor-quality fuel, suggesting that the problem began soon after refueling. The motorist, convinced that bad fuel was responsible, claims to have gathered video evidence showing the fuel sample in a mixed and compromised state. She insists that the sample, which was taken directly from her vehicle, appeared discoloured and inconsistent with what is expected of high-grade V-Power petrol. Despite presenting this evidence, Vivo Energy reportedly maintained that their tests found no issues with the fuel. The motorist is now escalating the matter, determined to hold Vivo Energy accountable for the damage. She has shared video evidence, showing the contaminated fuel and is calling for independent testing to verify its quality. Frustrated by what she sees as the company’s unwillingness to take responsibility, she is considering legal action and has reached out to consumer rights groups for support. This case adds to growing complaints from Kenyan motorists about fuel quality, with recent independent tests exposing major discrepancies in octane levels at several stations. An automotive content creator Kim JH of Tanuki Garage recently went around Nairobi, purchasing fuel samples from different stations and conducting on-the-spot octane tests. The findings revealed that some premium fuels, including Shell V-Power, underperformed compared to standard fuels. For instance, Total Limuru Road recorded the highest performance with a PON of 92, while Shell V-Power scored lower, challenging the common perception of premium fuel superiority. His findings, shared widely on social media, sparked outrage, with motorists demanding accountability from fuel retailers. Following the viral exposé, oil marketers, including Vivo Energy rushed to dismiss the findings, arguing that independent tests lacked credibility and did not follow industry-approved procedures. Shell Kenya, through Vivo Energy, insisted that its fuel met regulatory standards, pointing to tests conducted by the Energy and Petroleum Regulatory Authority (EPRA). However, the issue has refused to die down as more motorists continue to report unusual engine problems after refueling from previously reputable stations. Meanwhile, consumer advocacy groups have joined the debate, urging EPRA to conduct random and independent fuel quality tests at petrol stations across the country. They argue that the current reliance on oil marketers’ internal tests is inadequate and fails to protect motorists from potentially damaging fuel. The controversy has also drawn the attention of lawmakers, with some calling for stricter oversight and stiffer penalties for companies found selling substandard fuel. For motorists like the one affected at Shell Links Road, the issue is not just about technical standards but about accountability and compensation for the damage suffered. "Hi Nyakundi. I am Here to seek your intervention I fueled at shell links road ,vpower on Saturday, by the time I reached voi my car lost power I kept going but got worse as I moved. A few kms before kitui,the car stalled...I called a mechanic from kitui who came with a diagnosis machine and from what he said,I had put bad fuel. I towed the car back to msa. I reported to vivo. A guy from vivo by the name Brian mbaabu called and asked me to take the fuel for tests in their lab. He then called yesterday, on Tues and said that the sample passed all tests.... I asked my mechanic to open up the engine and to our surprise one piston is totally worn out an indication of bad fuel I will attach all I have including videos as I got the sample and it's all mixed up"

You’re on a journey on this kind of lonely road with your car and your car suddenly develops a fault, You can’t call for help and your lines can’t be reached due to network issues, what do you do? Except the car will stop and the engine won’t come up again, please reduce your speed and accelerate softly till you get to a nearby town, if it is an overheating issue, keep driving, put the gear in the neutral position and switch off the engine and let the car keep moving, switch it back on when you have to ascend a hilly road and the car can’t move freely on its own again. If the battery signal comes up while driving, chances are that your alternator has failed, or the alternator belt is damaged, apply the same method and switch off your AC, radio system or anything that may drain the battery while driving till you get to a safe place. If it is a flat tyre, maintain a low speed till you get to a safe place to change and use your spare, keep moving. Yes!!! Damage that tyre till you get to a safe place, just keep moving and make sure you have a spare tyre always and it is in a good condition. If the engine suddenly goes off on top speed, chances are that a fuse is damaged and this is why I will make a thread on how to identify different fuses and how to have them fixed temporarily in case of Emergencies. If your car jerks or experiences a lazy movement while driving, it’s likely to be a fuel related issue, fuel pump most likely, switch off the engine intermittently and put the gear in Neutral position, keep moving… if the fuel pump rests for about 5mins, it’ll pick up back when you ignite the engine, this will/may at least take you to a safe place or where you can have access to network to make calls. If you hear strange sounds like knocking sounds or the oil signal starts to blink, relax and reduce your speed, keep moving. Manage it till you get to a safe place or can have access to network. If your gear/transmission system isn’t selecting well, apply the same method, reduce your speed but keep moving, slow movement is better than no movement, your life and safety matters a lot. Please note that there are some Mechanical issues that nothing can solve on the road except patience and just to pray to God for safety and help, for example, you run into a pothole unknowingly and the oil pan hits the road and your engine or gear oil leaks away, or your ball joint or tie rod head pulls out, I’ll suggest you leave the car there, roll up your windows and lock up the car and start trekking till you get network or help, staying with the car may make you vulnerable to attacks or attract unexpected company, just keep walking away from the car for safety. Most importantly, please stay safe and be conscious of your environment. Be friendly with your Mechanic too or any Mechanic you see on the road. Don’t manage faults in cars and risk traveling with it.
