In the search for a supersonic train, China tests a Maglev that will reach 4,000 km/h. The problem will be maintaining it

by

China’s conquest of the high-speed train field is impressive. In the 2008 Beijing Olympicsthe country had just 120 kilometers of high speed between Beijing and Tianjin. 17 years latermanage more high-speed kilometers than any other countrya very long distance from Spain or Japan. They are not only building kilometers to unite the entire country: they are developing technologies so that the plane is no longer necessary. As? With Maglev trains at speeds of 1,000 km/h. And a specific model, the T-Flight, which dreams of 4,000 km/h. Maglev + Hyperloop. China is one of the countries, along with Japan, that is investing a lot of money in the development of the magnetic levitation trainsor Maglev. This technology allows trains not to rest their wheels on the rails, but rather to float thanks to a series of powerful magnets and an electromagnetic field. This allows us to exceed the 250 km/h that has been set as a standard for high speed and, for example, China has the fastest Maglev in the worldone that reaches 431 km/h. It is already operational between Beijing and Shanghai, but in Japan is testing one that will exceed 600 km/h. It’s a speed that will seem slow compared to what CASIC is preparing. It stands for “China Aerospace Science and Industry Corporation,” a state-owned tactical missile company that announced the T-Flight project in August 2017. The idea? Combine magnetic levitation trains with Hyperloop-style vacuum tubes. T-Flight. In short, it is putting a Maglev in a vacuum tube, eliminating air pressure and resistance as much as possible, but there is much more. For example, the idea of CASIC is that magnetic levitation is enhanced thanks to superconductors that will raise the train up to 100 mm above the rail. Conventional Maglevs are raised by about 10 mm, and the idea is that the higher the train is, the more stability it will have at extreme speeds. On the other hand, the tube itself, with a system that extracts air from it to create a low pressure environment, reducing aerodynamic resistance to the maximum. This partial vacuum and levitation that eliminates the physical resistance of the wheel and track is what will allow unprecedented speeds to be achieved. Achievements. In 2024 they already achieved one first validated test as a world record by reaching 623 km/h, but in the summer of this year, in a low pressure environment, The train reached 650 km/h in seven seconds in its laboratory. They were strange tests, since the track was a kilometer long when the usual thing is much longer, but that also gives us a clue of what brutal which is both the acceleration and braking of the train. That is, think that, in seven seconds and in just one kilometer, the train accelerated to 650 km/h and stopped. The team’s idea is to reach 800 km/h as the top speed this year, but the ambition goes much further. Ambition. Currently, the team is in Phase 1, which is the one that aims aim that speed of 1,000 km/h. To do this, and to validate the speed in real conditions, they want to extend the test track to 60 kilometers. However, the thing does not stop there and, when the project was born, it was already said that Phase 2 and Phase 3 would have as aim 2,000 km/h (almost double the cruising speed of a traditional commercial airplane) and 4,000 km/hsupersonic speeds that would compete with the fastest planes in the world. This would allow large urban centers in China to be linked in a few minutes, leaving aside the need to take planes to cover long distances. In fact, this high speed is already showing in Europe that short flights do not make sense if we combine the waiting time at the airport with the flight itself and compare it with the comfort of access to the train. A major challenge. Now, the goal will not be easy. Maglev technology works and is proven, but what they want to achieve with this T-Flight not only complicates things because, in addition to a track, a tube must be built. And, of course, maintain it. Extending this partial vacuum over hundreds of kilometers of tube represents an enormous technical challenge because it implies that the joints must be perfectly sealed, without the cold and heat dilating them so that there are no leaks. It is estimated that a 600 km pipe requires an expansion joint every 100 meters, and each one of them represents a potential point of failure. Furthermore, at 300 km/h appreciate vibrations in the seats. Air system to reduce pressure inside the tubes Furthermore, any decompression would be catastrophic and perhaps most importantly: there is no certification standard or safety protocols for something like this. In any case, T-Flight continues to take steps at a good pace and, although it seems difficult to see it working in the short term, if a country can achieve it right now… it is China.

It seemed like a game of imitating movements. It was actually diagnosing autism better than many clinical tests

by

When we think about video games, the fact of being a form of entertainment for young people (or not so young) or even that have an educational purpose. But they wanted to go one step further by betting on video games as a diagnostic tool for the little ones in the house and detect diseases early as important as the autism or the ADHD. The importance. Classically, both ADHD and autism are pathologies that they overlap from childhood, making early diagnosis difficult, which is the cornerstone in modern medicine to be able to tackle problems quickly. And this is what has been achieved with a video game that promises to differentiate a patient with ADHD from another with autism in less than an hour, just with the ability to copy the movements made by a silhouette on the screen. As we say, early diagnosis, especially of ASD, is really important to apply treatment that improves the quality of the child’s life and also begins effective interventions as soon as possible. Because although at the moment there are no treatments that are curative, it is possible to try to control some of the symptoms that are generated. Currently there are not many reliable and specific biomarkers to make this diagnosis, and this is a problem because autism spectrum disorder coexists with ADHD (attention deficit hyperactivity disorder) in 50-70% of cases. This overlap often results in a “confusing clinical picture” that leads to erroneous or delayed diagnoses that are ultimately a serious problem. Hard to detect. But diagnosing ASD is not easy either, because it is based in many cases on traditional evaluations of motor imitation, because the problem lies in mirror neurons of our brain. In this way, it is classic that if a baby He doesn’t respond by smiling when we make him smile. the case can be raised alarm. But this is a slow thing that requires highly trained observers and has limited reliability, precision, and scalability. The video games. And this is where the video game in question comes in to be able to give us the tools that we lacked on a daily basis to do the job. diagnosis of ASD. Something that a research team has achieved by developing the Computerized Assessment of Motor Imitation, or CAMI. A system that is a short task, lasting one minute, which has been designed as a very attractive video game so that you want to play. The system in this case uses different computer vision methods to evaluate the performance of the imitation without the need to place any type of sensor on the children and almost without human intervention to interpret the results that are generated. Imitation as key. The objective of the study was clear: To examine whether CAMI could identify imitation problems specific to autism compared to children without any type of illness or children with ADHD. In the event that a child could not imitate the movements that appear on the screen, we could be talking about a major problem that is causing all of this. But the obligatory question in this case is… Why do we look at the imitation of movements? The answer is that imitation performance is considered a promising biomarker that is quite specific for diagnosing autism. Imitation in this case is essential for social learning and interpersonal relationships, and its deficit has been associated with children who have ASD compared to healthy children. The challenge was to demonstrate that this deficit is specific to autism and not to other conditions with atypical motor profiles, such as ADHD. That is, if a child could not follow the movement that appeared on the screen it was due to a problem related to the autism spectrum and not because there was a problem in attention. The experiment. The cross-sectional study recruited 183 children between 7 and 13 years old. Participants were divided into four groups: ADHD (without ASD), ASD with co-occurring ADHD, ASD without ADHD (ASD only), and neurotypical children. The test consisted of two trials of one minute each, in which children were asked to stand up and copy the “dance” movements that an avatar made on the screen. The movements in these cases were recorded by the Xbox Kinect cameras and CAMI automatically calculated an imitation score for each trial ranging from 0 to 1, with one being perfect imitation. These scores were averaged to obtain a composite score. The result. The results were significant. Children with ASD, regardless of whether they had ADHD or not, showed significantly worse CAMI performance than neurotypical children. In contrast, children with ADHD alone showed CAMI performance similar to that of neurotypical children. But screening could also be done within patients who pointed to having ASD, since worse performance on the CAMI was associated with greater autism traits (measured by ADOS-2), specifically in restricted and repetitive social affect and behavior. However, performance is not associated with ADHD traits or general motor ability, which gives us a clue to be able to refine the diagnosis much more. The authors conclude that this CAMI method, which is low-cost and scalable, specifically distinguishes ASD not only from neurotypical development, but also from ADHD. Although currently a research tool, the findings lay the foundation for establishing CAMI as a definitive test to see if a child has autism or not.

China has taken a new step in its high-speed race. The CR450 has just reached a new milestone in its tests

by

China has spent years perfecting machinery that not only symbolizes speed, but also industrial precision. Its last exponent, the CR450has shown the scope of that search: in its most recent tests, two trains reached a combined speed of 896 km/h at the intersectiona new record in the Chinese system. It is not an isolated gesture, but a step within the innovation program launched in 2021 to raise the bar for high speed with more reliability and performance. The new registration was confirmed on October 21. During tests on the high-speed line connecting Shanghai, Chongqing and Chengdu, two CR450 trains crossed each other, reaching a relative speed of 896 km/h. In the same test campaign, one of the prototypes once again reached 453 km/h per unit, equaling the record set in 2023. The tests, they explain, are part of the “evaluation operation” that is currently being carried out on the Wuhan–Yichang section, a prior step to a more demanding phase scheduled for 2026. Speed ​​is on the table, but the operation is not yet At first glance, it might seem that two trains traveling at 453 km/h should add up to a crossing speed of 906 km/h. In practice, testing conditions prevent this. As China Railway Group explainedthe exact moment when both units are on parallel tracks it only lasts a few secondsand getting them to maintain the same speed at that point is extremely complex. For safety reasons, technicians increase speed gradually, ensuring stability and synchronization before attempting new records. The CR450 is not an isolated project, but one more piece of the railway plan that China launched in 2021 to raise commercial speed to 400 km/h. The challenge is not minor: maintaining that pace without increasing consumption or noise. Before entering service, the prototype must complete 600,000 kilometers of tests under real conditions, an essential requirement for its certification. This year, trials have extended from the Chongqing to Qianjiang sections to the Wuhan–Yichang line, where technical teams continue to fine-tune the train’s behavior in prolonged use scenarios. How Sina collectsmuch of the CR450’s advancement can be understood by looking inside its engineering. The train incorporates permanent magnet motors with a total power of 11,000 kW. The weight has also been reduced about 50 tons thanks to the use of carbon fiber and magnesium alloys, and the aerodynamic profile has been optimized with a longer nose, 15 meters. They claim that at 400 km/h, the noise level inside the car barely reaches 68 decibels. Although the CR450 has already demonstrated its technical capabilities, its commercial deployment remains without a clear destination. Today there is no operational line in China prepared to travel at 400 km/h. The first that contemplates this possibility is the Chengdu–Chongqing Central Line, approved in 2021 with a base design of 350 km/h and adaptable sections for future tests at higher speeds. According to China Economic Newsthe plan is that next year the train will undergo a more demanding testing phase there, the closest so far to a real service scenario. The development of the CR450 is divided between two of the main railway manufacturers in the country. The CR450AF version has been built by CRRC Qingdao Sifang, while the CR450BF is built by CRRC Changchun. Both They share an eight-car configuration —four engines and four trailers—. Official information indicates that they incorporate advanced communication and braking systems, as well as high stability bogies designed to maintain balance even in extreme speed tests. The immediate future of the CR450 passes through the aforementioned line, where over the next year it will undergo tests closest to real operation. There is still no confirmed date for its entry into service, and those responsible for the project emphasize that the priority continues to be technical validation. For now, we have to wait to see if all the promises of the program materialize and if the new train manages to transfer its laboratory achievements to the operational field.

Listen to the judge, weigh tests and send a verdict with the mobile. It is not a dystopia, but the latest in immersive theater

by

There are people capable of anything in order to dodge the task of being part of a jury, because they do not want that responsibility in their conscience or because you do not feel like investing a considerable amount of their time in determining the fate of others. But … what if we condensate all the tedious process in a couple of thrilling hours? What if we did to have fun? Would we even pay for it? What’s up. ‘The Jury Experience ‘is an immersive play in which spectators become an active part of the show, analyzing testimonies, examining forensic tests and listening to allegations. Finally deliberate and offer a final verdict of guilty or innocent. The cases are accessible and not especially violent or disturbing, they are often inspired by real events. How it works. The development of ‘The Jury Experience’ is ambiguous enough so that there is no “correct” resolution. There are no conclusive evidence in development, there are no last -minute confessions. That is, the responsibility of awarding someone a conviction or an acquittal falls entirely in the public. According to the organizers From this interactive entertainment, “the proposal invites you to reflect on justice, personal responsibility and limits of perception and social judgment.” Where to see it. Currently, ‘The Jury Experience’ is turning all over Spainand has been seen in Madrid, Barcelona, ​​Valencia, Sevilla or Alicante, among others. At the time of writing these lines you can see it in Bilbao, but the work does not stop traveling. Moreover, it is already starting to operate as a franchise, and to raise different cases so that the most aware can repeat. If a crime was judged in autonomous cars and accidents with cyclists because of artificial intelligence, in the second we will judge a more classic intrigue, with a love triangle, a conflicting divorce and a crime in a mansion. Experiences from within. ‘The jury experience’ is not an isolated experiment. Currently, especially in capitals such as Madrid and Barcelona, ​​immersive theater experiences abound. Although there are often those oriented to the whole family (such as those of Plot Point ‘Superdetective’ and ‘The fantastic legend of Calamburia’), there are others aimed at a more adult audience, such as the different versions of ‘Cluedo’ live, which already has several cases. There are even places especially dedicated to gender, such as 4DX Theater List Box In Madrid, where apart from the entire aforementioned ‘cluedo’ franchise, they have works such as ‘the memory of the psychiatric’. What the True Crime. There is an interesting hook in this phenomenon that allows the temperature of the tastes of the public: the Claim of “based on a real case” multiplies the morbid of the Devotos del True Crimethat they listen Podcasts And they see series inspired by authentic crimes often calibrating the possibilities they would have had to take the investigation by another route. Even in a highly fictional environment, such as ‘cluedo’, public participation allows it to transform it into a True Crime Without consequences. A new morbid fun, and also a perfect thermometer of where our leisure pulls. In Xataka | There are thousands of people hooked to True Crime documentaries on YouTube.

Grok 4 destroys the tests and aims to be the most advanced AI model. The problem is that Elon Musk continues to sabotage his answers

by

Xai has launched Grok 4its new artificial intelligence model that is sweeping the most demanding performance tests in the sector. The model exceeds OpenAi, Google and Anthropic proposals in multiple benchmarks. And is that in the absence of knowing OpenAI’s strategy with GPT-5At the moment it has all the ballots of being the most pointer the model. However, Grok continues to drag the usual problems: controversial responses, offensive content and an Elon Musk using the model to subtract credibility. The numbers speak alone. In the test Humanity’s last examconsidered one of the most difficult to measure abilities of AI, XAI states that Grok 4 has achieved 25.4% Without additional tools, surpassing O3 of Openai (21%) and Gemini 2.5 Pro from Google (21.6%). But it is with Grok 4 Heavy, its multiagente version, where the results shoot: according to the company, reaches 44.4% With ‘tools’, almost doubleing competition. Image: XAI In addition, at the benchmark ARC-AGI-2which measures the ability to solve complex visual patterns, Grok 4 has obtained 16.2%practically double the next commercial model. According to Musk“Grok 4 exceeds the doctoral level in all subjects, without exception”, an affirmation that, although it sounds to marketing, is supported by the results obtained. The revolutionary approach. Grok 4 Heavy works with A “multiple agents” system that work in parallel about the same problem, then comparing their results as if it were a study group. This architecture allows you to climb intelligence according to the available computational power, a concept that could redefine how we understand the AI ​​performance. Image: XAI The usual problems. The launch of Grok 4 occurs just after the previous version of the chatbot published anti -Semitic comments In X, even identifying as “Mechahitler” in some answers. XAI had to temporarily withdraw the service and eliminate offensive publications, while countries like Poland They announced complaints before the European Commission and Türkiye blocked access to chatbot. The cause was a modification in the system instructions that allowed the model “not to avoid politically incorrect statements.” Although Xai withdrew that guideline, the damage was already done. A constant sabotage. Despite these technical advances, Musk continues to condition Grok’s responses in ways that compromise their usefulness. The model performs automatic searches for the opinions of the tycoon in X to respond to controversial issues, turning the alleged search for “truth” into an echo of its creator’s ideas. This practice, confirmed By experts in AI like Carlos Santana, he once again demonstrates how Musk’s controversial decisions are directly influencing the development of the model. In addition, several researchers already They have managed to avoid Easily model safety barriers, making it generate content on chemical weapons, malicious software, drugs and other sensitive issues through relatively simple jailbreak techniques. Ethan Mollick, professor at Warton and an expert at AI, Point out The lack of transparency of the company: ‘There is no detailed technical documentation, risk analysis or explanations on how to avoid future incidents’. This opacity makes it difficult for companies to trust Grok for critical applications. Grok 4 prices. XAI Grok 4 Basic offers at a price of about 30 dollars a month. However, the company has also launched Supergrok Heavy, a subscription of $ 300 per month in which its most advanced model is offered and that directly becomes the most expensive market service on the market. What is coming. XAI plans to launch a programming model in August, multimodal agents in September and video generation in October. Also will integrate Grok 4 in Tesla vehicles Next week, expanding the scope of AI throughout the Musk ecosystem. The question is whether the company will separate the technical excellence of the media controversies that surround it, or if it will remain hostage of its founder’s impulsive decisions.

We have just found new tests of Ozempic’s benefits in another field: dementia

by

Although drugs pass exhaustive controls dedicated to, among other things, detect side effects, their clinical use allows us to find out new details about their effects on the body. This includes associated risks, but also possible additional benefits we did not count on. Lower risk of dementia. Drugs destined to keep blood sugar levels under control in people with diabetes (such as Ozempic or Zepbound) They can have a positive effectreducing our risk of dementia. Several studies have deepened in this relationship, offering hopeful results in this regard. Diabetes and dementia. Diabetes is one of the Risk factors that we usually associate with the appearance of dementia, such as age, tobacco, certain genetic factors or cholesterol, among others. Diabetes It is also a risk factor in arterosclerosis and stroke or stroke, which are factors that also contribute to certain forms of dementia. Knowing this, it can be intuitive to think that drugs that help us keep diabetes at bay can have this type of effects. However, intuition is not enough, so several research groups take time to work to better understand the underlying interactions and be able to strengthen our knowledge about the issue. Two studies. A few weeks ago, the magazine Jama Neurology He published two independent studies on each other who tried to investigate this issue. Both focused on how drugs aimed at reducing the amount of blood sugar were associated with a lower risk of dementia and cognitive problems among people with type 2 diabetes. Reviewing the evidence. One of the studies It was based on the systematic review of scientific literature related to the subject, review accompanied by a meta -analysis, a quantitative study of the results compiled through the review. This analysis was carried out from 26 randomized essays among which were added about 165,000 participants. The team responsible for the study did not find a significant change in the risk of dementia when studying the set of treatments focused on glucose reduction. But he did find that agonists of the peptide receptors similar to type 1 glucagon (LPG-1), the family of compounds to which the semaglutida belongs and therefore Ozempic, were related to a risk of suffering from 45% lower. One more essay. The second of the studies mentioned focused on two drugs, the agonostas of the GLP-1 receptors (LPG-1st) and the sodium/glucose collection inhibitors 2 (SGLT2is). The team observed that both the LPG-1ras and the SGLT2is were linked to a lower risk of suffering some forms of dementia such as Alzheimer’s in contrast to other treatments destined for glycemic control. A key factor. Studying the link between diabetes and dementia can open the way to better understand a disorder as complex as dementia. There is still little that we know about cognitive deterioration associated with age and disorders such as Alzheimer’s, but in increasingly aging societies, finding ways to reduce their weight in the well -being of older people will become unavoidable.

We have been asking if the eggs are good or bad for our health. The tests are very forceful

by

It is a debate that we have surely heard countless times, that of how good or bad that eggs result for our health. It is a setback, the evidence that eggs are “bad” is limited and has been refuted by various studies, but still the issue remains the subject of new studies. Studies that continue to insist on the usual consumption of eggs does not represent a risk additional. Another study on the list. A recent study of mortality associated with egg consumption has not observed indications of an increase in mortality associated with egg consumption. Moreover, the study found an inverse relationship between the regular consumption of this food and the risk of deaths linked to cardiovascular diseases. The study He followed up of 8,756 over 70 years of age, which gave information about their diets. Based on this information, the team separated the participants in three groups: who did not consume eggs or did it shortly, those who consumed eggs between one and six times a day, and those who consumed eggs daily. Verdict. The study results indicated that people in the moderate consumption group had a risk of mortality by 15% lower than those of the low consumption group, controlling other factors. They also observed a 29% reduction associated with specific mortality due to heart disease. Of egg aspirin. The study was framed in the ASPREE project (Aspirin in rear Events in the Elderly), curiously, a project dedicated to the study of the effects of aspirin in preventive medicine. The details of the study have been published In an article In the magazine Nutrients. But they didn’t have cholesterol? “Eggs are a dense food in nutrients, they are a rich source of protein and a good source of nutrients, such as B vitamins, folate, non -saturated fatty acids, fat -solub vitamins (E, D, a, and k), hill, and numerous minerals and trace elements,” explained in a press release Holly Wild, co -author of the study. However, the eggs won a bad reputation due to their cholesterol content. Each egg has about 275 milligrams of cholesterol, which would represent almost the entire recommended amount of cholesterol, they explain In an article for The conversation Lauren Ball and Karly Bartrim, experts from the University of Queensland, in Australia. The trick is in absorption, Ball and Bartrim point out. And it is that the fact that we consummate a food with high cholesterol content does not mean that our body will absorb that cholesterol and make it end in the bloodstream, where it can imply a risk. This is the advance. The debate on the hypothetical damage that eggs may be a health risk has been perpetuated for years has often been used to discredit advances made in the field of nutrition. And it is true that the science that studies nutrients and their effects on our body is complex: the varied of the human diet and the immense complexity of our body are two factors that make extremely difficult to measure the effects of some foods on our health. It is not surprising Therefore we can occasionally run into this type of debates. The contradictory results are not alien to any field of science: there are many reasons why a study can yield erroneous results, such as methodological failures, calculation errors or even by mere statistical chance. That is why relationships must be studied several occasions, by different teams and following a variety of methods, this is how failures and erroneous relationships have been detected on several occasions. It is how the method itself should work. In Xataka | White eggs have disappeared from our supermarkets: the story of how brown was commercially imposed Image | Morgane Perraud

Finding quick and reliable tests for Alzheimer’s is a key mission for science. And we have a new candidate

by

Ahead of Alzheimer’s. It is a simple but difficult objective to achieve since the symptoms of this disease tend to appear when the disorder is advanced and has already caused important damage to our brain. A difficult objective but what It can help us treat the disease With greater efficacy, managing to delay the appearance of some of its symptoms such as cognitive deterioration. Maybe one day helps us cure it. In the blood. A group of researchers has tested a new blood test aimed at the early detection of Alzheimer’s disease. The test is based on a biomarker present in the blood, P-TAU217, which shows changes long before the appearance of symptoms in people with the disease. The study showed precision when detecting the disease greater than 90%. These results also did not depend on the age or gender of the participants, either on the existence of comorbidities or whether the test was carried out by specialists or primary care personnel. This marker can be measured with simple and cheap tools and the process is automatic, which can facilitate detection in various circumstances, democratizing the diagnosis of the disease. “This is an important step to bring simple blood tests for Alzheimer’s disease to health systems around the world,” said the team responsible for the essay in a press release. P-TAU217. Detection methods based on the P-TAU217 compound They are not exactly new. These types of tools are already implemented in the United States and it is expected that they will soon reach the rest of the world, says the team itself. The new method seeks to offer a simpler alternative to the available tools. The new study analyzed the precision of this New Test in the conditions in which it would be used, not only in specialized clinics but also in primary care. In three countries. The essay was carried out from 1,767 participants with cognitive symptoms distributed in three countries: Spain, Italy and Sweden. The details of the study were published In an article In the magazine Nature Medicine. The New Test included two cut points. One of them served to interpret the negative results: from this threshold the test rules out the presence of the disease. The second of the cut points serves to find the positive ones: this threshold shows the presence of the disease. This leaves, between one cut and another, a “gray zone” in which the results are inconcuing, however the use of a test with a single threshold slightly reduced the accuracy of the diagnostic tool. Above 90%. The study showed that the test achieved an accuracy between 92% and 94% when used in its two cuts mode. However, this precision fell to levels between 83% and 87% when only a cutting point was used and applied to more advanced ages. “When the method was tested in patient sides, the precision was between 92% and 94%,” NOëlle Warmenhoven explainedfirst signer of the study. “This is promising since this method will probably become one of the most used in clinical practice around the world.” In Xataka | We have a new “theory of all” to understand Alzheimer’s.

Toyota 4Runner 2025: Analysis, characteristics and handling tests

by

In 1984, Toyota launched the market 4runnera car that quickly became a favorite to make off-road. Today we tried for the first time the 2025 Toyota 4runner. Read also: Toyota unbalance Tesla as the most valuable automotive brand The sixth generation of the 4runner comes in 9 different versions and two motorization options. As is the case of the Trailhunter, a totally new model equipped with an I-Force Max hybrid engine that generates 326 horsepower. The second option, which equips lower versions such as SR5 and TRD Sport, It has a 4-cylinder 2.4-liter turbo engine that generates 278 horsepower and 317 torque pounds. You can read: Ford Ranger 2024: The best Pick-up in North America As for details, the 2025 Toyota 4runner Trailhunter stands out for having an Old Man Emu suspension, ideal for overlanding and carrying the adventure much further. On its front, the light bar, LED lights and fog lights, in addition to black exterior details. It comes with 33 -inch tires, 18 -inch bronze alloy wheels according to the version and has a 6,000 -pound -towing towing. As for prices, the 4runner trailhunter has a base price of $ 66,900.

The Toyota 4Runner 2025 with hybrid motor will be available in the United States from February 2025. TOYOTA 4RUNNER: A history of off -road evolution From your debut in 1984Toyota 4runner has established itself as one of the most respected names in the segment of SUVs. This model, which combines off-road capacity, durability and reliability reputation, has evolved significantly throughout five generations, adapting to the changing demands of drivers without losing their robust essence. The Toyota 4runner made its debut as a modified version of the Toyota Hilux, designed to offer more comfort without sacrificing off -road capacity. The interior of the Toyota 4runner 2025. Credit: Toyota.Credit: courtesy The first generation From the 4runner he appeared as a compact SUV with a removable hood, which made it ideal for outdoor adventure enthusiasts. It had a 2.4 -liter four -cylinder engine and, later, a V6 version was offered, responding to the growing demand for more power. Although its design was simple, with basic interiors and a utilitarian approach, this first version laid the foundations of what would become an iconic model. The second generation Of the 4runner marked an important transition when adopting a completely closed body design, leaving behind the removable hood. This change improved the safety and isolation of the vehicle, making it more attractive to families and travelers. In addition, an independent front suspension was introduced to improve road driving, without compromising its off -road performance. The 3.0 -liter V6 engine gained popularity in this generation, although it still faced criticism for its moderate power. Despite this, the 4runner continued to gain followers thanks to its reliability and its ability to face difficult land. The third generation From Toyota 4runner marked a significant change towards a more refined and advanced SUV. It was completely redesigned on a new platform that maintained its body of bodybad, ideal for off -road adventures. That generation offered more powerful engines, including a 3.4 -liter V6 engine, and improved significantly in terms of comfort, equipment and technology.
