While we wait for solid-state batteries, the University of Córdoba has an idea for the electric car: human poop

by

The automotive industry has launched itself into electrification arms. Be with the hybrids, plug-ins either 100% electricthey all have batteries, and the key to convincing more users of make the jump from your combustion car is guarantee greater autonomy. The solid state batteries are one of the technologies in researchbut there are other very promising ones such as lithium-sulfur, and the University of Córdoba believes that there are two secret ingredients to improve the formula. Urine and excrement. Li-S. They are not new. We have been talking about the lithium sulfide batteriesand while we find the economy of scale necessary for solid-state ones to establish themselves, lithium-sulfur ones are one of the hopes for electric cars. They have twice the real energy density of lithium-ion, sulfur is extremely abundant and economical compared to critical materials such as cobalt or nickel, It is not something that China controlsit is safer because the risk of thermal runaway is lower and the environmental impact is reduced. They are not perfect, since the conductivity is low, the manufacturing processes are not as optimized as those of current alternatives and, above all, the current useful life is very limited: although they are moving forward In this sense, just 300-500 charge cycles compared to between 1,000 and 3,000 for lithium-ion batteries. However, as we say, they have become a promising technology, and the University of Córdoba wants one of the ingredients in the battery to be… poop. Batteries from waste. The Chemical Institute for Energy and the Environment, or IQUEMA, of the University of Córdoba has published a study in which they test the potential of sludge from a municipal treatment plant when converting it into activated carbon. It is an essential material for lithium-sulfur batteries, since it works as a conductor, and they consider it to be the answer to the challenge of optimizing the electrodes of these batteries. As we said, sulfur has advantages, but one of the great deficiencies is its conductivity index. This requires active carbon and other conductive matrices that are expensive to produce. But of course, if this conductive matrix is ​​created from waste that all cities in the world produce no matter what, things change. Villaviciosa de Córdoba. To do this, IQUEMA has used sludge from the wastewater station of Villaviciosa de Córdoba. This plant uses a treatment system that generates a sludge with an interesting composition to carry out the experiment: It is rich in organic matter. Also in metals, nitrogen and phosphorus. Combining them can create a material with a good electrochemical performance index. The process is as follows: Drying: the mud is dried and pulverized. Chemical modification: Potash is added as a chemical agent to make the material more porous. Pyrolysis: the mixture is subjected to temperatures of 800º to convert the organic matter into activated carbon. Mixture with sulfur: thus it is trapped in the active carbon matrix and the last step would be to integrate it into the battery electrodes. Promising. The researchers have found that the activated carbon obtained has ideal properties to be used as a material in these batteries. Its porous structure and nitrogen doping improve the transport of electrons and ions, and the resulting material has a high sulfur content. This allows the battery to have great electrochemical stability. That is to say, one of the big problems of this technology, the low conductivity of sulfur for the cathode, is something that mitigates the matrix created from the Villaviciosa de Córdoba sludge. And because its raw material is what it is, it is easier to recycle than other conventional batteries for which you have to develop tadjacent technologies for sustainability. According to the researchers, it is an avenue worth exploring because “triple the storage capacity of a lithium-ion battery”. “It is a great advance that we achieved from a waste that we considered problematic” – IQUEMA researchers Beyond the poop. Considering the results, it is likely that we will see more studies in the same direction. It is something that solves a double problem: the municipal waste management by converting it into a key material to solve one of the challenges of lithium-sulfur batteries. And the interesting thing is that IQUEMA has not remained only in the sludge of the sewage treatment plant. Previously explored the potential of agroindustrial byproductslike the olive pits and avocados, but also almond and pistachio shells. The problem is that these materials are already in demand in other sectors (such as composting or heating), and that is where the great advantage of human excrement lies: “no one” wants them.

Chinese electric car manufacturers opted to develop their own chips. He already plans to sell them to others.

by

In 2024, Nio advertisement the world’s first 5nm chip for autonomous driving, being an important step towards technological independence from a Chinese manufacturer of such caliber. A year and a half after its announcement, the company is now beginning the external marketing of that chip, according to they count from Latepost. In this way, Nio is on the eve of transforming one of its most expensive investments into a potential source of income. Just like point The electric vehicle maker has already begun providing technology licenses to an automotive chip company. A multimillion-dollar project that seeks profitability. The development of Shenji NX9031 It has involved an investment of billions of yuan. William Li (Li Bin), CEO of Nio, revealed that the R&D expenditure on this chip was equivalent to the cost of building 1,000 battery exchange stations, which would place the investment above 140 million dollars. The project, started in 2021, has involved more than 600 professionals covering front and back design, verification and testing. What makes this chip special. Made with automotive-grade 5-nanometer technology, the Shenji NX9031 promises approximately four times the computing power of Nvidia’s Orin-X. Zhang Danyu, head of Nio’s chip division, pointed out in May that in some of their specifications they even surpass industry-standard chips and that their mass production began several months before Nvidia’s latest smart driving chip, the Thor-U. It is currently integrated into models such as the ET9, ES6 2025 and EC6. How much does a technology license cost?. According to share From Latepost, the value of these license agreements varies significantly depending on the type of authorization. An individual intellectual property license could be worth several million dollars, while a technical authorization at the system-on-chip (SoC) level could reach hundreds of millions of dollars. A new source of income. That the Nio chip begins to be marketed externally comes at a great time for the company, especially now that the manufacturer faces pressure significant from investors and has promised to become profitable in the fourth quarter. The company has intensified its efforts this year to reduce expenses and explore new sources of income. In March, Li Bin already advertisement publicly at the China EV 100 Forum that Nio chips and operating systems would be open to the industry. “If they want to buy the best chips, they can contact Nio,” he said then. What it means for the future of Nio. According to Li Bin, the chip provides a cost optimization of approximately 10,000 yuan ($1,400) per vehicle in the brand’s own models. Now, with the external license, Nio not only recovers part of its investment, but also positions itself as a technology provider for other manufacturers in the automotive sector.

When you bought a car you were supposed to control it 100%. The industry has managed to make us lose our desire

by

An owner of a Hyundai Ioniq 5 N recently discovered that he couldn’t perform one of the most basic maintenance tasks on his electric car: changing the brake pads. The reason has nothing to do with how complex or not the task was mechanically, but rather with Hyundai’s proprietary software and the professional-level credentials necessary to access it. The episode has reopened the debate on the repairability of electrified vehiclesin an era in which we increasingly need professionals specialized in software and electronics in workshops, and carrying out maintenance on our own is increasingly more complicated. The underlying problem. Brake pads are wear components that any car needs replacing periodically, although in electric vehicles they last longer thanks to the regenerative braking. On most cars, this job can be done at home with more or less basic tools and moderate mechanical experience. However, the Ioniq 5 N incorporates an electronic parking brake that must be fully retracted by a computer to allow changing pads, and then recalibrated to adjust to the thickness of the new parts. What it cost the owner. According to shared user SoultronicPear on Reddit, no conventional diagnostic scanner worked on his 2025 Ioniq 5 N. After trying several options, he purchased a subscription to Hyundai’s J2534 software (costing $60 per week) and an approved adapter (about $2,000). Still, the system didn’t work. After contacting the software developers, he discovered that the Windows version was not updated for the 2025 models, while official dealers use a completely different program based on Android. a barrier. When I finally received the updated version of the software, a new obstacle appeared: the system requested credentials NASTF (National Automotive Service Task Force), a US organization that validates professional mechanics and regulates access to sensitive vehicle functions in the country. According to TheDriveHyundai’s technical documentation states in red that “access to two-way tests and special functions requires NASTF Diagnostic Professional or Vehicle Safety Professional credentials.” Therefore, the owner could not access this adjustment firsthand. Hyundai’s position. The middle consulted to the firm, which defended its procedure arguing reasons of security and functionality. “The official repair procedure requires placing the rear calipers into service mode using our Global Diagnostic System or the J2534 app. This ensures proper functionality and customer safety,” a spokesperson explained. The company he added that it is exploring ways to make routine maintenance easier by “balancing convenience with security,” and that its official tool is available for anyone to purchase, although it is worth mentioning that its price is around $6,000. Beyond legality. Technically, Hyundai does not violate the laws of law to repair because it offers access through systems compatible with the J2534 standard, not only through proprietary equipment. However, what has always been a task accessible to individuals with moderate mechanical knowledge who wanted to do it on their own, has been relegated exclusively to professional workshops, at least in this case. A growing problem. Although the case focuses on Hyundai, the Korean brand is not the only one that makes repairs on modern vehicles difficult. The electrification and digitalization of automobiles is creating new barriers for owners and even independent workshops, who also cannot access these functions. For many enthusiasts, this takes away autonomy over their own vehicles and creates confusion, especially for something that should be as accessible as routine car maintenance.

A study analyzed the power of LED car headlights. The conclusion is what all drivers already know

by

I hate traveling at night, almost as much as drive in rain. It had been a while since I went to a national one, but a few days ago I had to do it and what had to happen happened: I was dazzled on more than one occasion. Car headlights have evolved tremendously in a short time and LEDs have prevailed in new vehicles. The problem is that every time there are more signs that we have gone too far with its evolution. And a new report puts a percentage on how dangerous they can be if they are not properly calibrated… or if the car that uses them is an SUV. In short. Whether because you have a new car or because you update the headlights of a car with a few years behind it, they are one of the elements that are most appreciated on the journeys. They see you better, you see better and it is one of the most important points in terms of safety behind the wheel. If the height is correct and they are well calibrated, they are a pleasure, but it can also happen that this is not the case and they dazzle or dazzle you. There, security goes to hell for a few seconds. The British Department for Transport has published the results of a study about glare caused by LED lights. Your conclusion? They represent a road safety problem, altering the habits of drivers in the United Kingdom. We could extrapolate it perfectly. Basically, between October 2024 and early 2025, they combined objective measurements in real conditions with surveys of 1,850 drivers. The results They are devastating: 97% of them affirm that they are frequently distracted, and 96% that glare from headlights is a road safety problem. Analysis. On the one hand, we have those statements from drivers, who were asked about the frequency with which they felt distracted due to glare from the headlights of vehicles traveling in the opposite direction. On the other hand, the objective analysis. To do this, the DfT used luminance cameras and mixed the data using a machine learning algorithm to identify the variables that come into play at high glare levels. They discovered that there was a strong correlation between higher luminance levels and reports of glare in some test vehicles (logical, on the other hand). Also that road factors influence, such as circular upwards or curves to the righttimes when drivers’ eyes are most exposed to the beam of light from the headlights. In the end, these are things that a study does not have to confirm if you have ever driven at night, but what is interesting about the study is the consequences and the “culprits.” Impact. For example, more than half of the respondents have affirmed that this discomfort due to glare has generated anxiety when driving at certain hours, which is why they have reduced night driving or have abandoned it altogether. And more than 20% point out that they would like to take the car less at night because of this, but they have no other option. According to statistics and beyond the indirect impact, they estimate that glare has bound about 290 accidents annually. and the effects They depend on age: a 50-year-old person takes nine seconds to recover from glare, while a 16-year-old takes just one second, which applies another risk factor on the road to older drivers. SUV. Beyond this, they have also found that larger vehicles, such as SUVs, are the most associated with glare in surveys. This is logical: they are taller, their headlights are more aligned with the eyes of drivers traveling in the opposite direction (especially in lower cars) and it seems that all new cars are SUVsso they are the ones with the most up-to-date lights. The problem of retrofit. This term in English refers to the modification of an existing component. In short: updating with new parts and superior technologies, such as changing the brakes for better ones, installing a new infotainment system or change the original halogen headlights for LED ones. You can buy new ‘bulbs’ even on Amazon and many are approved, but there are two problems: those that are not well regulated and those that are installed illegally. The British Administration has identified that illegal conversion is a problem, since changing halogen bulbs for LED means that those housings designed for halogen do not work the same with the new LED headlights, causing dangerous glare. British ITV has intensified its analysis of the sale of these kits, with heavy fines for violators. Not simple solutions. They estimate that around 800,000 vehicles fail their annual inspection due to headlight alignment problems, but although these are UK numbers, this is a global problem (in Spain22% of serious failures have to do with the lights) which implies that, perhaps, we have gone too far with the power of our cars’ headlights. The solution is not clear. The report recommends periodic glare checks and rethinking luminance measurements in modern headlights, but this will have to be studied. In the end, it is something that we all suffer at one time or another although, as they point Our colleagues at MotorPasión, for motorcyclists there is another added problem: reflections on the visor itself.

Volkswagen has presented its “most intelligent car to date” in China. The trick is that Volkswagen hasn’t done it

by

Volkswagen prepares the launch of the ID. UNYX 08an electric SUV developed together with the Chinese firm Xpeng that will hit the market in 2026. For years, Volkswagen enjoyed a large presence in China. However, currently, firms such as Xiaomi or BYD have overtaken them to the right with their proposals and technology. The German group has had no choice but join forces with the Chinese Xpeng to continue competing in this very competitive market. And the greatest exponent of this alliance is this same car of which we are going to tell you all the details. Strategy to come back in China. The German brand has lost positions in this market since 2020, when electric vehicles began their massive expansion in the country. Now it is trying to recover the lost ground against local manufacturers such as BYD and Geely through this technological alliance with Xpengwhich provides its G9 platform and its connectivity and driving assistance systems. Design speed. The ID. UNYX 08 was completed in 30 months, a time that according to Volkswagen It is more than 30% lower than usual. This acceleration responds to what the company calls “Chinese speed”, a concept that reflects its need to adapt to the pace of the local market. The German manufacturer affirms having managed to “fully integrate into China’s automotive ecosystem” thanks to local alliances and its own research and development capabilities. The figures of the new SUV. The vehicle measures 5 meters long, 1,954 meters wide and between 1,672 and 1,688 meters high, with a wheelbase of 3,030 meters. These dimensions exceed those of the Xpeng G9, the model on whose platform it was built. It will be available in two configurations: a 230 kW rear motor or dual motor with 140 kW front and 230 kW rear. will ride LFP batteries from CATL, with a range of more than 700 kilometers according to the CLTC cycle, and will support 800-volt fast charging. Technology at the service of the Chinese driver. The ID. UNYX 08 will incorporate L2++ level driving assistance with the capacity for autonomous operation “from parking to parking” both in the city and on highways. It will also have OTA (Over-the-Air) updates and an artificial intelligence assistant based on advanced language models. Volkswagen presents it as “its most intelligent model to date.” The plan to get back into the fight. This SUV is the first of the two models agreed between Volkswagen and Xpeng in 2023. It will be assembled in collaboration with Anhui Jianghuai Automobile Group, a partner with which Volkswagen created its first joint venture in China in 2017 dedicated exclusively to new energy vehicles. The ID family. UNYX, which already includes the 06 (a compact SUV) and the recently unveiled 07 (an electric sedan), thus expands into the medium-large SUV segment. What’s at stake. For Volkswagen, this launch represents much more than a new product: it is a litmus test on its ability to compete with Chinese manufacturers in its own territory. The Asian market has become the main battlefield of electromobility worldwide, and the German brand needs to demonstrate that it can offer cutting-edge technology without losing its identity. We’ll see if the ID. UNYX 08 convinces drivers in China. If you do so, it will set the course of your strategy in the country.

an underwater YangWang, a 29-meter dune and a car that turns on its own

by

The circuit seems taken from the dream of a megalomaniacal engineer: A gigantic dune indoors. A 70 meter pool for cars, not for humans. An impeccable and very wide asphalt route. A gymkhana off road with unevenness, slopes, gravel… BYD has called it Racing Trackwe have gone to Zhengzhou to see it (and test it), and it is much more than a circuit: it is a declaration of intent on the part of its manufacturer, and a not-so-subtle signal of the role it wants to occupy. Not in China, but in the world. Is permanently tighten muscleis throwing the gauntlet to Europe and the United States to see if they keep up. And for us, it is the key to understanding how this manufacturer has gone from a local phenomenon to a world leader in five years. The U8 dune The interior dune is the pride of the complex: 29 meters high, 28 degrees inclined, more than six thousand tons of sand from the Alxa desert. Guinness has certified it as the largest indoor building in the world. He Yangwang U8a luxury SUV with four electric motors, was in charge of climbing it. Of course, a local driver was behind the wheel. On the sides of the dune, dozens of journalists waiting for the climb like a child waiting to open gifts the night before Three Kings Day. Image: Xataka. Image provided. Image: Xataka. Image provided. At one point, the pilot honked his horn and accelerated hard to scale the sand wall. A five-meter tank that went with an unnatural calm. Not a skid, not a hesitation. Just an electrical hum. Another honk, and the descent. Applause and that feeling of celebration of raw power. We missed hitting each other in the chest making simian gestures. But there was something else: that iconic Pirelli advertisement said that “power without control is useless”, and that aphorism fits perfectly here. The U8 is pure power, but full of control. Symbolism. Where cars breathe The next stop was the wading pool, a 70 meter long pond created for the U8. This time we didn’t drive either, but we were inside while the pilot submerged the car in the water. Upon detecting a certain depth, the car automatically raised the windows and opened the sunroof, two safety measures to prevent water from entering the cabin and to facilitate escape if necessary, respectively. Image provided. Image provided. Image provided. Image provided. From there, the motors work like turbines in each wheel. They keep the car afloat and also allow you to steer it. It was impressive to see the water almost at the height of our window. From there, a gentle 180º turn and return to the shore. Science fiction for a amphibious SUV. That said, this function is intended as a response to an emergency such as flooding. It is not something the manufacturer recommends doing for fun. The dune was fun, but The one in the pool was the most hypnotic moment of the dayalthough with a bitter aftertaste due to memories of DANA. But for extreme situations like that this function is supposed to be there. From water to dust with the Denza B5 After the show, it was our turn at the Off-Road Parkan area with 27 difficulty scenarios. We did it, not completely, at the wheel of the Denza B5, the SUV that will arrive in Spain under that brand – although in China it is sold as Fang Cheng Bao 5 -. A competitor to the Land Cruiser that, depending on its price (it will arrive in Spain) will manage to put Toyota in more or less trouble, but in any case it will be noticed. If you don’t know Denza yet, keep his name: technological luxury that has no reason to have any complexes. Image provided. Image provided. Image provided. The assigned circuit was easy: ramps designed to put the car on two wheels, notable inclinations, bridge crossings and areas of complicated relief. Even so, the B5 moved with solvency. Instant electric all-wheel drive and obstacle-filtering suspension with the aplomb of a veteran off-roader. Patrol, is that you? It was not a risky experience, but it served as a symbolic demonstration: Chinese electric cars are no longer only looking for efficiency. They also want to be the most versatile. This one is. And it was extremely easy to drive in those environments even for someone like me, with no experience off-road. The scary crab: Denza Z9 GT The turn of the Denza Z9 GTthe saloon shooting brake that BYD has launched against the Taycan and the Panamera. But we didn’t test it on curves, but on something more disturbing: the crab walk and the U-shaped turn, 180 degrees in static. He crab walk —advancing diagonally like a crab—is a fair trick until you see it in action. You accelerate forward and the car slides sideways, defying all visual logic. It takes a few seconds for the brain to accept that the rear wheels turn in the opposite direction to the front wheels. It is useful for parallel parking without maneuvering. It’s unsettling to drive. And it attracts looks of bewilderment. Image provided. Image provided. But the static 180 degree turn was straight up surreal. Standing still, without moving an inch, The Z9 GT pivots on its own axis until it turns completely around. The four wheels rotate independently, locking one of the front wheels, the car rotates like in a video game and you, inside, only hear the hum of the engines while the world spins outside the window. There’s no need. It is not practical on a day-to-day basis, if perhaps at some specific moment where we do not have an angle to deface a mess But it’s the kind of technological excess that separates a good car from a statement of intent. Of course, it does not seem advisable to play with it too much for the sake of our support tire. “Mickey Mouse” with … Read more

Elon Musk boasted of having created an “apocalypse-proof” car. Now the Tesla Cybertruck’s headlights are falling out

by

Who doesn’t know a C15, prays to any Tesla Cybertruck with this title we headed this article in July 2024. We did it because on social networks it was already common to find comparisons between a Tesla Cybertruck which began selling just half a year before for a price close to $100,000 (sometimes much higher) with the car of “a Spanish farmer flying with three bags of fertilizer and a pregnant sheep in the trunk”, as this X user described. It was no wonder. Since it was first announcedElon Musk did not stop boasting that Tesla’s future electric car was nothing short of indestructible. A story that began crack when, live, the car glass itself could not resist the launch of a steel ball that, in theory, should not have caused any scratches. Now, less than two years after the car went on sale we know that the crack has been getting bigger and bigger. Because Tesla has recalled its Cybertruck for review. This time there have been 6,200 units. It is the tenth time in less than 24 months. Now, the headlights are going out. Indestructible, when it does not self-destruct Elon Musk boasted during the Tesla Cybertruck launch event about having a car “apocalypse proof”. He was talking, we assume, about real apocalypses, not metaphorical ones like the one they are experiencing Tesla sales in Europe. Beyond the jokes, what the owner of the company wanted to show is that he had something like a “armored street car”. In Xataka We already explained why a car that does not deform is a bad idea. If the car does not absorb the impact, it is the passenger who suffers the impact against himself. We are talking, of course, about cars that are on the street, working with all the guarantees. The problem for Tesla is that it keeps call cars for inspection. In the first year he had to do five calls for review. Today it has already been 10 and there are two full months of 2025 ahead, they collect in Electrek. While it is true that some of the problems have been solved with simple software updates, on other occasions they have had to go to the workshop because they were losing pieces in progress. The problem, everything indicates, is the same as on this occasion. The Tesla Cybertruck has some unusual headlights falling out, according to the American media. That is why the NHTSA has had to activate a recall so that 6,197 Tesla cars return to facilities. And Tesla sells headlights that can be installed on the roof of the vehicle as an accessory in its after-sales network, expanding the car’s off-road characteristics. The problem is that those headlights fall out. The glue simply cannot withstand their weight and in some circumstances it ends up expiring. This It hasn’t been the first time that Tesla has problems with the glue used, which has led to calls for review because, among other elements, the decorative molding of the A pillar, the one located on the side of the windshield, fell off. Beyond the possible fun of having an indestructible car that pieces are falling off while movingTesla is experiencing an ordeal with the electric off-roader. The company had the opportunity to make it a flagship, aspirational model and always sell it at a very high price but without aspirations of turning it into a mass product. like Mercedes does with its G-Class. However, it opted for the opposite and now finds itself unable to put the promised versions on the market at affordable prices. But, above all, it does not seem to be selling the expected numbers. And the company says it has a production line ready capable of produce 125,000 units each year. Musk even boasted that they expected sell more than 250,000 units annually. Electrek They point out that less than 65,000 units have been sold since November 2023.

Toyota was determined to make hydrogen the perfect alternative to the electric car. Hyundai has just invested 563,800,000 euros

by

Time passes and the hydrogen car continues to be the great promise of clean mobility. The problem is that, little by little, time passes and hydrogen seems to be at the same point: challenges that seem impossible to solve and the eternal promise of revolutionizing transportation. Along the way, a good handful of companies said they were joining the hydrogen wave. Toyota has been one of those that has bet the most but, in the midst of a decline, it has been Hyundai that takes a new step. Reconversion. Hyundai has confirmed which has already laid the first stone of its new fuel cell and electrolyzer production plant in Ulsan (South Korea). The company has invested 930 billion won. That is, 563.8 million euros to convert the space and give it a new industrial use. According to the company, starting in 2027 they will be able to manufacture 30,000 fuel cell units per year in a space that extends across 43,000 m2. The intention is to produce systems for hydrogen-powered passenger cars but also for heavy transport services. a bet. Hyundai’s commitment to hydrogen is not new. The company has on the market the Nexusone of the few hydrogen cars that can be purchased and that has no competition since the Toyota Miraithe other great hydrogen car, is a sedan with a totally different approach. At the end of last year, Hyundai also presented Initiumthe preview of what should be a new hydrogen car that will arrive in 2025. However, the company has not launched the new model on the market. The Nexo has not been the first car powered by a Hyundai fuel cell but, for now, it is the last despite the fact that in 2021 they announced that we would have the entire range on the street with hydrogen versions in 2028. The promise. For years now, hydrogen has been proposed as the great alternative to the electric car. Although, really, it is an electric car. In its operation, a fuel cell car is a vehicle that carries out the electrolysis process inside to generate electricity that is stored in the batteries. In this process, the car does not generate CO2 and only expels water vapor through the exhaust pipe. The great advantage is that its carbon emissions are non-existent while it recharges the tanks in a few minutes to travel hundreds and hundreds of kilometers. The problems. There are many and they are difficult to remedy. When it comes to bringing hydrogen to a street car, the technical difficulties are enormous. First, because hydrogen occupies a large volume for the energy it can later generate. That’s why the Toyota Mirai is, almost everything, huge tanks. The latter is solved by turning the hydrogen into a liquid state but requires keeping it at -30ºC. It is a solution that has been designed to be used as fuel in a combustion engine and to remember the sensations of a combustion engine but generates very polluting particles such as NOx. That is, hydrogen requires huge tanks or a good amount of energy to keep it at a very low temperature. When this is achieved, it requires a complex system to carry out electrolysis or burn it in the engine itself (which generates very polluting particles). And all this without counting the complexity of producing and transporting it to the service station on duty. Non-viable. What happens at this point? That hydrogen is, at the moment, very expensive. As expensive as in Germany the cost of filling the tank was as expensive as filling it with diesel. It does not seem so strange that service stations are being dismantled in Germany and that although Stellantis offered to convert electric vans to hydrogen to gain autonomy, has ended up abandoning his plans. For now, on the way BMW too says it is developing hydrogen cars. Renault says to do the same. And Toyota continues investigating with burn hydrogen in combustion engines while turning his back on his Toyota Mirai in the United States where he faces a class action lawsuit from owners who they feel cheated. a light. In addition to light transportation, Hyundai says it wants to focus fuel cell production on heavy transportation. The company has its hopes that this type of transportation can find a true use for hydrogen. Heavy transport can find some advantages over electric transport. To charge an electric truck in a short time, enormous infrastructure is needed with chargers as fast and powerful as those from BYD. If hydrogen poles are created in dry ports or large distribution centers, it could make sense with less dispersed and therefore less costly distribution. Also the cost of filling the truck with huge tanks is lower because in percentage terms it would not eat up as much space as in a car. And, at the same time, recharging would be faster for less clean transportation than purely electric but much cleaner than current diesel engines.

The best-selling car in Spain is the Dacia Sandero. It is a completely irrelevant fact to understand Spain

by

The Dacia Sandero was, in 2024, the best selling car in Spain. It was, in fact, in a total of five countries around the world. In addition to Spain, the Sandero repeated the throne in Bulgaria, Kosovo, Morocco and Portugal. This year we are on track to repeat it, with a Dacia Sandero that has added 28,765 units. Well above the MG ZS, the second best-selling car with 19,251 euros. The data tells us that among the best selling cars In our country the cheapest vehicles triumph. The Renault Clio is the third option. Despite having announced a new generation, it is still the third best-selling car in our country and can be found for prices starting at just over 16,000 euros. The Seat Ibiza is the fourth best-selling car and its starting price is just below the 15,000 euro border. Among the 10 best-selling cars we also find the Peugeot 208, which starts at 17,000 euros. Are we poor? This is what many responses on social networks affirm to each and every one of the lists of the best-selling cars in the world. The reactions compare us with the Nordic countries or Belgium, where the Tesla Model Y was the best-selling car last year. But… what if the statistics were distorted? Simply looking at which is the best-selling car by country gives rise to some paradoxes. France has a salary average of 44,968 euros, while in our country we move at 31,698 euros, according to data collected by Expansion. Despite this, the best-selling car in France in 2024 was the Renault Clio… followed by the Peugeot 208 and the Dacia Sandero. Photography is not very different from that of our country. Finland has an average salary of 52,893 euros, double the 25,198 euros in Greece. Both, however, share that the best selling car in their countries last year it was the Toyota Yaris Cross. The same car that repeated as the best-selling in Poland. Now, we can understand that the photograph may be somewhat distorted. Bestseller just means “bestseller” “The fact that sales were concentrated on that type of car (the Dacia Sandero) or on its price level, that it was the best-seller did not say anything about our purchasing capacity” Who maintains this is Manuel HidalgoDoctor in Economics from the Pompeu Fabra University and professor at the Pablo de Olavide University (Seville). He did it with a tweet on According to his calculations: 33,251 euros. That is the average price of cars bought in Spain. And the data even has nuances that would raise this figure. We might think that a very expensive car will undoubtedly raise the average price. For example, a Dacia Sandero sells for less than 15,000 euros, so a car worth 150,000 euros is equivalent to the registration of ten of these cars. Source: Manuel Hidalgo But Hidalgo has also crossed the frequency with which these cars are purchased. And in the graph above you can see that, indeed, there is a good number of vehicles sold at the average price of a Dacia Sandero and then there is a spike when the graph approaches 20,000 euros. However, most cars sold In our country they stand at 30,000 euros, very close to the average of 33,251 euros. From here, there is a marked drop. The professor and Doctor in economics explains that to obtain the data he has taken the data of the best-selling cars in our country between January and September 2025 (latest data available) and has crossed them with the RRP of the price at which each and every one of the cars in our country are sold. These data show that six times more cars are sold at the 30,000 euro border than at the 14,000 euro border where the Sandero starts. The leadership of the latter is based on the fact that it is the market reference among the cheapest cars. The options in this price range are also much more limited, so at higher prices sales are diversified and, therefore, it is more difficult for a car to gain points to appear among the 10 best-selling cars in our country. But, as we said, it is very likely that the average price we pay for our car in Spain be taller. We asked Manuel Hidalgo about this possibility and he confirmed it. It must be taken into account that the data shown is obtained with the RRP of the car but not with the expenditure that the private client makes on equipment or superior mechanics. And the basic versions of a car are, in many cases and more so in cheap vehicles like the Dacia Sandero, focused on large fleets. This explains that if the car is segmented between individuals and legal entities, the curve shifts to the right. Source: Manuel Hidalgo According to the data collected by Manuel Hidalgo, the average of the car purchased by an individual is higher than the average of the legal entity. Specifically, an individual spends 33,982 euros per vehicle, while an individual spends 32,376 euros. Looking at the graph above, we see that it is common to buy cars for very low priced fleets. So much so that the graphs between individuals and companies do not equalize until both reach 20,000 euros. Among individuals, the frequency of purchases between 20,000 and 30,000 euros shoots up earlier and it is evident that the final average price is driven by a rebound in purchases between 50,000 and 60,000 euros. Among individuals, it is evident that there is a purchase for fleets and work vehicles where the cheapest cars are sought. Then, the frequency shoots up again at the border of 30,000 euros, showing that it is the segment preferred by companies for cars used by their employees or by self-employed people who can deduct part of the fees. That is, yes, in Spain the most purchased car is the Dacia Sandero but the variables that must be taken into account to analyze the … Read more

BYD has built a megafactory in record time. And it’s not just a car factory: it’s a city

by

The chinese automotive industry has one goal: flood the west with their cars. BYD is one of the companies that, while wanting to take over the national market, wants a good slice of the international pie. For this you have as many employees as a small countryand to carry out its vision it has the most beastly car factory you can imagine. This is the Zhengzhou plant, and more than a factory, it is a city. Gigafactory? Best Uberfactory. Everything that surrounds the Zhengzhou plant It is imposing. Starting with the times, BYD and the Henan government they signed the project in September 2021, in just one month the works began and less than two years later the factory began production. His ability It is imposing and, already in its first operational phase in April 2023, it demonstrated that it could have a ability 400,000 vehicles annually. Not only did they get it up and running in record time: its dimensions are also impressive. The plant is estimated to have an area of ​​10.68 square kilometers in factories alone, but when the project comes to completion, it will occupy about 130 km². Context. Ten times more than Tesla Gigafactory in Nevadawith its 12 km², and larger than the area of ​​the city of San Francisco (it is approximately 120 km²). It is not unusual for large technology companies to have “cities” under their control and, without leaving China, Huawei has a similar campus (and another that copy different European cities). But BYD is overwhelming. More than cars. The factory is a “living” project of which four phases have been completed so far. The first two have focused on the production of cars, but as we said, we are talking about a factory that goes beyond vehicles. The third phase launched a plant for the battery manufacturing and the fourth has the necessary facilities for the production of semiconductors. They are underway new phases to expand production to two million vehicles annually and it is estimated that the facility generates a complete vehicle every 50 seconds. Technology. This is achieved thanks to an automation rate of 98%, one of the highest in the automotive industry worldwide. For example, the welding process is carried out with 91% robot labor and there are hundreds of them operating in other sectors, such as assembly or logistics. It is not due to a lack of human work, since the factory currently employs about 60,000 people, 90% of them coming from Zhengzhou or its surroundings and there are plans to reach up to 200,000 employees in 2026. Imagine all of Salamanca working in the same factory. Independent Republic of BYD. That is why we are not just talking about a factory: it also has housing and everything necessary is being built to make it a full-fledged city. Apart from housing blocks for employees, the megafactory has canteens, commercial areas, recreational facilities such as soccer fields and other areas for playing sports, as well as an internal transportation system. It also has additional facilities to carry out tests on their vehicles, such as a 1,758 meter circuit with nine curves, sand dunes to carry out off-road tests, a 70 meter pool (this is where you can see the Yangwang U8 in action) and multifunctional areas to carry out braking, acceleration and other more specific tests, such as autonomous parking. Apart from testing, it is like an amusement park for those who want to see the benefits of the brand’s EV cars. International connection. In the end, it is a mix between ambition and space (something that is abundant in China), which gives rise to a city focused on a single task: producing new energy cars with which China is setting the standard globally. In addition, it is an economic engine for the region and such a strategic element that, in 2024, Zhengzhou inaugurated the International Land Port with a one kilometer railway line to the BYD base. In this way, BYD can produce cars and instantly send them by train to the international market. It is also easier to load them into RO-RO boats with capacity for reach Europe in three or four weeks. Such is the importance of Zhengzhou for the company that its seventh ship car carrier was named after the city.
