China is telling us what a future full of electric cars looks like. And we already know which are the most reliable brands

by

The conquest of China in the automobile industry global has made us increasingly pay attention to the country’s manufacturers and the models that are coming out every year. China leads in new energy vehiclesalthough the reliability of their cars has always been questioned. The latest report Quality test launched by the analysis firm LandRoads offers us a very interesting perspective, as it studies the models that have initially caused the least problems since their purchase. In this aspect, the ranking places the Xiaomi SU7 as the most reliable large sedan, while the Tesla Model 3 dominates among the midsize models. Below these lines we tell you all the details. What is the ranking about?. LandRoads has published its annual report on quality in electric and plug-in hybrid vehicles in the Chinese market, analyzing 6,950 incidents reported by users. According to the report, 3,687 were quality problems and 3,263 were design-related. In the overall ranking by brand, AITO tops the list with a quality risk index of 123 points, followed by Mercedes-Benz (126) and Tesla (146). Image: ChinaEVHome. Source: LandRoads Why does it matter? The Chinese electric vehicle market is immersed in a frenetic race to incorporate more technology and functions. However, the study gives us clues that not all manufacturers are facing this battle completely well. The three main problems reported were noise (24.6% of complaints), exterior components (18%) and failures in intelligent systems (17.3%). Together they represent more than 60% of incidents, pointing out the critical points where the industry needs to improve. Categories. Highlights of the report indicate that: In medium-large sedans and above, the Xiaomi SU7 wins with an index of 108 points, well ahead of the Stelato S9 (218) and the IM L6 (237), according to LandRoads data. In midsize and compact sedans, the Tesla Model 3 leads with 104 points, followed by the Nio Firefly, BMW i3, Geely Galaxy Xingyuan and BYD Seal 06 GT. Among large SUVs, the top three spots go to AITO models: the M9 (88 points), M8 (98) and M7 (135), with the Li Auto L8 and Voyah FREE completing the top five. In medium and compact SUVs, the Avatr 07 stands out (92 points), ahead of the BYD Sealion 05 EV, Yuan UP, Tesla Model Y and Yuan Plus. In MPVs, the Voyah Dreamer records the best result with 192 points. Balance. The report also points out a phenomenon he calls a “high-equipment, high-risk concentration zone.” And according to LandRoads, as some manufacturers rapidly accumulate new features, the maturity and stability of the systems does not advance at the same pace, amplifying the risk of vehicle quality. According to the study, AITO, Xiaomi, NIO, Zeekr, Li Auto and Voyah have managed to maintain low risk rates despite offering high levels of equipment. More mature electronic architectures, better coordination with suppliers and exhaustive validation systems in all types of scenarios come into play here. Looking long term. LandRoads concludes in its study that the electric vehicle industry is moving from simply adding features and functions to the integration capacity and long-term stability of all these novel systems. Furthermore, seeing Aito above manufacturers like Mercedes or Tesla gives us clues about the transition we are experiencing and the ability of Chinese manufacturers to produce a product that lives up to it.

There is a trick to make AI models more reliable: talk badly to them

by

If you greet ChatGPT and thank it when it responds, you’re not getting the most out of it. Some researchers wanted to check if the tone we use when asking the AI ​​for things changes the results and they have discovered something interesting: being rude makes them more trustworthy. Rude. They tell it in How to AI. A study carried out by researchers at the University of Pennsylvania has analyzed whether the tone we use when writing a prompt has an effect on the result and the conclusions are clear. Prompts with a ‘rude’ or ‘very rude’ tone elicited up to 4% more accurate responses than those with a more polite tone. The study. To test it, they generated a list of 50 questions on different topics such as history, science or mathematics. Each of the questions was asked using five different tones: very polite, polite, neutral, rude, and very rude. The model they used was ChatGPT-4o. The results. The researchers did ten rounds with all the questions in different tones and the conclusions are very clear. If we look at the variations, the difference between the neutral or rude tone is only 0.6%, but at the extremes the difference becomes more evident. When using a ‘very friendly’ tone, the average accuracy was 80.8%, while if we went to ‘very rude’, it increased to 84.8%. Kindness by default. We tend to speak kindly to chatbots, this is reflected the survey that Future conducted at the end of 2024. At least 70% of respondents admitted to using “please” and “thank you” when using AI chatbots. Many claimed to do so as a matter of custom, culture and “because it is the right thing to do”, although a small percentage admitted to being afraid that robots would rebel in the future. It is expensive. Regardless of the reasons that lead us to be kind to AI, there is a reality and that is that “please” and “thank you” have an absurd cost. When we thank ChatGPT, requests to the language model increase, which increases electricity and water consumption in data centers. We don’t have figures, but Sam Altman assured that kindness has cost OpenAI “tens of millions of dollars well spent.” The prompt. Despite the enormous advances in AI, language models continue to amaze and are not 100% reliable. However, many times the fault that the answers are not exact does not lie with the model, but with how we are asking it. There is tricks to get a good prompt and being friendly or using fillers like “if you can, I would like to…” is one of the points to avoid. It is not a question of treating them badly either because that does not contribute either, but the more direct and clear you are, the better the result will be.

There are more and more and better plugs for electric cars but Tesla continues to lead. The recipe: cheap and reliable loaders

by

Holy Week of 2024. Dozens of Tesla cars They queue in a Cañavate Atalaya charger (Cuenca) in the middle of any place. The situation went viral and because scenes were repeated in Mérida and Albacete. The waiting were 15 or 20 minutes in many cases but also exceeded the time in others. They all had something in common: Tesla Load Stations. Despite the jokes and despite the intention of ridiculing the owners, in Xataka We broke a spear in favor of those drivers And we count why they had happened. If Holy Week has taught us, it is not missing chargers for electric cars. What are missing are reliable plugs. So we titled. Year and a half later, things have changed. Not only in Spain, also in the United States. But, nevertheless, Tesla still has the best load experience. And that is still key when selling the car. Tesla chargers are still ahead The data this time comes from the United States but the situation is extrapolable to what happens in Spain. JD Powerspecialists in motor market analysis, has analyzed the status of the United States recharge network and its conclusion is very simple: there are more and more chargers available and increasingly spoil. But Tesla continues to lead, with much, satisfaction among electric cars when you have to recharge a vehicle. Keep in mind that the United States has a huge Loading deficit. Especially if we consider that distances are huge. If the country is wanted to embrace the electric car to a greater extent it is necessary to create a good network of loaders as fast as reliable. A good part of that network is now in the hands of Tesla, where most users load. They do not even have a Tesla. The latter is key to understand why satisfaction with the price of loaders and the load experience has fallen in the last year. According to their data, drivers are less happy with both points because they observe that, for them, prices are more expensive and the most rough experience than for Tesla users. Something curious occurs, therefore. According to JDPOWER, the level of failed visits (the charger does not work correctly or is out of service) is the lowest in four years and the number of drivers who have reported these failures (14%) is also lower than in 2024. General satisfaction, however, has fallen. The Tesla Network is so good compared to the competition that the users themselves have pressed to the manufacturers of other cars to the point that they have assumed the Tesla standard to load, modifying their own cargo ports. The best user experience In Spain (and Europe) that is not so because fast loaders are all (except for the first Japanese cars) CCS2. That is, the plugs are the same for everyone. But Tesla’s experience is still above. To understand it, we resume the case of Holy Week in 2024. This year the same have not been observed issues. Or not, at least, with the same seriousness as last year. It is logical, as we said that happened. Tesla has “kidnap” the owner of his cars in his own ecosystem. Tesla did something very intelligent since her birth. It was as simple as proposing their own load stations. Thus they guaranteed to give a confidence network to those who made the leap to a completely new company (and technology). They also took advantage, to create synergies of which the rest of the manufacturers have not arranged. First, his recharge were free. Now that is a thing of the past but their prices are still lower than those of the competition. This guarantees that, in the day to day, the Tesla user prioritizes the load in their stations. But saving a few euros on a very specific day is no reason for users to prefer to spend more than an hour stopped before recharging the vehicle. If those queues were formed, it is because the Tesla recharge network is very reliable. In fact, myself when I try the cars of any company for our reviews soil to prioritize Tesla plugs Because they have never left me. Only Zunder has offered me this same experience. With the rest of the companies I have had problems of malfunction or inoperance. It is logical, therefore, that if a Tesla driver has hurried the autonomy of his car is reluctant to go to another load point, consume a good part of the little percentage that remains reserved and risks that the plug of another company does not work. He will think: “Better wait here for an hour than to go to another place, Not being able to load and have to call the crane“ To this we must add that Tesla’s user experience is the best because they have eliminated small frictions that are very appreciated on a day -to -day basis. It is something similar to Apple’s ecosystem. Can you have a Mac, an Android phone and use some AirPods in the latter? Yes, but there are small barriers that the average or little advanced user will hurt especially. The same goes for the electric car. Tesla has one of the best software in the market and, probably, the best route calculator. Prioritize your chargers and show you in real time the occupation of it and advances a possible wait. When you arrive, the vehicle detects the loader, opens the load gate and plugs the hose in the car. When it is time to continue, the mobile phone warns you and as the car is associated with a credit or debit card, nothing must be done. The position will be passed. Simple. When one carries in Tesla supercargers with another car you have to Log in the mobile phone and select the load point you will use. You have previously had to register the card. Finally the position will be passed. This process has to repeat it with Each and every one of the companies … Read more

The throne on the list of the most reliable cars of 2025 has changed. What does not change is Japan’s domain

by

Usually, after a house, The purchase of a car It is the second greater expense that we have to face. It is still something indispensable in the day to day of us, But with upward pricesit is necessary think very well what is bought. Apart from choosing a motorization model or personal tastes, it is always advisable to take an eye on the lists of the most reliable cars in the market. And the new analysis of Consumer Reports It is a great help to make that decision. Changes in the noble zone. Although they focus on the US market, there are common models in different territories and lists like the one we have in hand or JD Power’s are very interesting. They handle reports sent by thousands of consumers, analyze several key points of new cars and are so relevant that some of their findings They have forced brands to take action (such as the failure in the rotary engines of Mazda in 1973). Every year they make their list with the most reliable car brands, Those who go down the least for the workshopand in which they have just published they take reports from 2022 to 2024, as well as the first bars of 2025. Normally, it was a boring table, but in this year’s edition we see that Toyota and Lexus, who had been dominating for years, have lost one position each due to the rise of another brand that, to anyone’s surprise, remains Japanese: Subaru. Graph | Consumer Reports The tail does not change. The domain of the Japanese in the upper part is a constant in recent years, this reliability being one of the presentation cards held by cars in the ‘rising sun’. In the lower part of the reliability list there are also some position changes, but the names we see are the same (and the countries too). If the Japanese stand out above and in the middle part of the South Koreans like Kia or Hyundai, in the lower part those who dominate are the Americans. Jeep, GMC or Cadillac are not well stopped. Nor does the German Volkswagen (again) and the red lantern is Rivian. The one who became the Third most important car manufacturer in the world In the stock market, they collapsed in record time, losing 90% of its value in just three years. It is the brand that worst score takes this year’s list. And if you are wondering where Alfa Romeo, Mercedes, Mitsubishi or Fiat are, from CR points out that they did not have enough data to be able to add them legitimately to the list. We will see if for the final report of the year contemplating everything 2025 changes the thing. What do they analyze. View the list, let’s see the data and conclusions of Consumer Reports. For this year’s report, they have asked their members about the problems they have had with their vehicles in the last 12 months. In total, data from more than 300,000 vehicles from 2000 to 2024 have compiled, but as we said, also with 2025 models that have had sufficient units on the street to be relevant to the compilation. They analyze 20 problem areas ranging from brakes to the engine, through broken embellishness, potential problems outside battery, transmission and problems that affect the electric and hybrids as the battery and load and create a score for each vehicle from 1 to 100. Hybrids stand out. As they point out, all that previous experience and the data of newer models have allowed this year’s list to be the most complete for hybrids and electric. They claim that they continue to improve, but that if there is a king on all electrified, they are the HEV hybrids. Jake Fisher is the technical director of Tests at Consumer Reports and points out that, although hybrids “remain extremely efficient in fuel consumption, they also offer reliability that is similar to conventional combustion cars despite their added difficulty.” He continues to affirm that “on average, they have a similar number of problems that cars propelled by a combustion engine” and comments that the most reliable models are from Toyota, Lexus, Kia and Hyundai, with cars such as Corolla, Rav4, Elantra el Sorento, Highlander or Lexus NX. But with reservations. It also points out that not all hybrids are the same and that Ford, for example, has a reliability problem with both the F-150 as with the F-150 hybrid. In addition, they strive to indicate that the most reliable of electrified are pure hybrids, since PHEV or plug -in hybrids They are less reliable. And, as a final recommendation, from the report they clarify that, although a brand can be very reliable, there are always models that stand out and others that lower the average. If we are interested in particular, it is worth looking for information from that and not getting carried away by the general reliability guides. And they say it with a specific model in mind: the TOYOTA BZ4Xbeing the one that lowers the score of the brand. Interestingly, it is the basis of Subaru’s single, and also lowers the average of this company.

An older comet that the sun has invaded the solar system. The old and reliable Hubble telescope already has photos

by

The veteran space telescope Hubble, With 35 years of service behind themcontinues to demonstrate that it is in full form. His last feat has been to capture the first clear image of 3i/Atlas, an interstellar kite that not only comes from outside our solar system, but seems to be older than the sun itself. The interstellar object number three. 3i/Atlas is the third celestial body beyond the solar system that astronomers have detected on our neighborhood, after the mysterious Asteroid 1i/’Oumuamua In 2017 and the Gigantic Comet 2i/Borisov In 2019. The images, taken on July 21 by NASA’s space telescope, offer a detailed first view of the new member of the club. The first alert was given by an astrophysic student nicknamed Astrafoxen In his bluesky profile: “There are many cosmic rays around, but the comet’s comma looks fantastic and bulky.” And indeed, even without processing, the images let a diffuse and active atmosphere intuit around the code core. An unexpected composition. Scientists have already begun to reveal the secrets of the comet. A Preliminary study Based on previous images, he revealed that 3i/Atlas is an active interstellar kite that contains abundant water. However, its cloud of dust looks more like that of type D asteroids: rocks full of silicates with organic molecules, carbon and water ice inside. The composition of the comet’s comma seems to be adjusted 70% to Tagish Lake Meteoritewith the remaining 30% in water ice grains. An older cosmic fossil than the sun. Everything indicates that 3i/Atlas comes from a region of the Milky Way much older than ours. With an estimated age of 7,000 million years, compared to the 4.6 billion years of the solar system, this kite is a time capsule of an era before ours, which especially excites astronomers. First detected on July 1, 2025 by the Atlas poll, the comet has become the priority objective of observatories around the world. One of those who will join the hunt is the Vera C. Rubin Observatory, which with The world’s largest digital camera promises to find many of these invaders.

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.

The more and less reliable car brands of 2025, in a graphic dominated by Japan and with a surprise: Tesla

by

Buying a car is A authentic headache. It is logical if we consider that, usually, after the house, the purchase of a car is the greatest expense we make. There are many variables to take into account (motorization, securitymore or less screens …) and something that should be seen are the lists of the most reliable cars. There are several, Like those of Consumer Reports Or JD Power, who help us make the decision. And, precisely, in this graph elaborated by Visual Capitalist We have the list of the most reliable brands of 2025 according to one of these databases. JD Power. First of all, let’s see the context of this company. Founded in 1968, it has been specialized in handling big Databases that collect consumer data in various industries. One of them is that of the car, where they analyze all those data to prepare reports with achievements such as the discovery of a defect in the design of the rotary engines of Mazda in 1973, something that forced the company to remedy. In the automobile segment, they publish several lists, being one of them that includes the general degree of satisfaction of the owners of the different brands. On this occasion, it focuses on the United States, but as is the case in the Consumer Reports lists, although the US market is slightly different from the European, many of the brands and models are common in both markets. PP100. To understand the list, you have to know that the number of problems per 100 vehicles is detailed (problems per 100 or PP100) after three years of property. For example, in the Last year listJD Power collected the response of more than 30,500 people from cars bought in 2021 and, after three years, detailed the problems belonging to nine categories: Abroad Inside Seating Driving experience Air conditioning/air conditioning Controls Infoentrate system Engine Driving aids The best. Going to the list, we have a recurring company in the first position: Lexus. In different consumer surveys, Toyota’s luxury brand has been crowned as the company that has the most degree of satisfaction among its customers. In this case, although it has more errors than in the list last year, it continues in first position. The American Buick is the second and, thirdly, Mazda advances to Toyota. Nothing surprising: Japan continues to lead in the high satisfaction positions, but others like General Motors manage to sneak because they have varied the most with respect to the previous period. The biggest changes. Precisely, there are several changes in the list marked by that improvement or worsening in front of the 2024 survey. Mazda is one of the one that improves the most with respect to the last year, reducing its PP100 by 24 points. Ford reduced it at 31 points and Tesla starred in the biggest change by reducing it by 43 points. There are also changes worse, such as that of the aforementioned Toyota, Alfa Romeo, Hyundai, Acura or Jeep, something that surprises less if we see recent movements of the company in American territory, with policies that are not liking and other determining factors for this list. Worse. The really interesting, beyond the brands whose reputation improves or worsens in recent months, is the fact that, globally, the average errors per 100 vehicles has reached, according to JD Power, its highest average since 2009. This is curious because it was the year immediately later to the financial crisis of 2008 and the manufacturers may cut in components, but cars analyzed in 2024 They are built during the Covid-19 pandemic, which points to a correlation between a crisis moment and an increase in vehicle failures. More technology, more problems. The more options a device has, the more possibilities there is something fail. It is something that surely you have heard: do not buy you a washing machine because it surely fails more than a washing machine and a separate dryer (insert the example you want with a microwave-shock or whatever). Well, in the case of cars, according to JD Power reports, half of the main problems of the entire industry are related to the great novelty of recent years: integration with smartphones and systems ANdroid Auto and Apple Carplay. In fact, in surveys, 56% of users claim that they have not noticed improvements even after updates and that, the more software related to the Infoentrate It has the car, there is more likely that something fails. Obviously, Millions of cars are sold a year And many have that integration, but also owners or solutions such as Android Automotive and the units that fail represent a small percentage. But, in an industry that becomes more and more in this and Use of screens (With brands that are already reculating), It is normal for more mistakes of this type to appear. Choosing a car now does not go only motor or design, but also of stability in the software, and it is convenient that we keep it in mind when choosing.
