Essai Honda Civic S+: un parfum de Prelude

25 septembre 2026 à 14:08
Honda Civic e-HEV

La Civic hybride, que nous avons eu l’occasion d’essayer par le passé, fait l’objet de subtiles évolutions. Au premier rang desquels un mode S+ qui donne à la berline Honda un parfum de Prelude. Direction les routes du sud-Charente pour en prendre le volant.

Une Civic universelle

Polyvalente, accueillante et spacieuse, la Civic répond a tous les besoins ou presque. Et ce même si ses dimensions généreuses, 4m56 de long, sont taillées pour les grands espaces. Avec pas moins de 270 000 exemplaires vendus l’an dernier aux États Unis et au Canada, elle est y incontournable. Mais le best seller de Honda n’est plus comparable à une Golf… qui n’est plus vendue aux États Unis!
Alors même si on se plait à imaginer la même Civic dans un format plus compact, force est de reconnaitre que cette onzième génération est réussie sur bien des aspects. Pratique et sûre, la berline n’oublie jamais d’être confortable même en voyageant à plusieurs. Spacieuse elle dispose d’un coffre modulaire et ds rangements astucieux. Bien suspendue, elle se joue des mauvaises chaussées et des ralentisseurs d’entrées de ville. Son sens « Civique » se traduit aussi par un appétit d’oiseau, grâce a un système hybride efficace et bien pensé, le e-HEV. Qui se voit enrichi d’un mode S+.

En amélioration continue

A priori rien ne distingue cette évolution, à part l’arrivée d’un nouveau coloris Gris Météore Métallisé, hérité de la…Prelude. Une invitation discrète à découvrir ce qui change. A l’intérieur, on retrouve la même sobriété, ou l’écran central ne capte pas toute l’attention. Sur les version Sport, des surpiqûres rouges sur la sellerie, les garnitures de portes et le volant font leur apparition. Un liseret rouge entoure dorénavant les grilles d’aération. Pas de bouleversement, donc, mais voilà qui rehausse discrètement l’ambiance. Ce rouge distingue la version Sport du premier modèle de la gamme, l’Exécutive et de la finition haute Advance. Cette dernière, riche d’une sellerie tout cuir et d’un toit ouvrant panoramique partage dorénavant son système audio à 12 haut-parleurs avec la version Sport. Advance et Sport disposent toutes deux du mode S+ qui n’est pas proposé sur l’Exécutive. 

Au parfum de Prelude

Que l’on ne s’y trompe pas. La Civic n’est pas devenue une Prelude à 4 portes. Au cas ou nous l’aurions oublié, Honda nous a confié le volant du coupé durant les essais. Le châssis affuté, la direction ciselée et les freins Brembo restent l’apanage de la Prelude. Tout comme l’ambiance à bord, les excellents sièges ou la position de conduite plus basse.
Mais la Civic sait donner plus de plaisir que par le passé. Au moins pour ceux qui gardent une appétence pour le moteur thermique, ses bruits ou ses changement de rythme. Comme c’était déjà le cas, la direction, les suspensions et la gestion moteur sont orientés vers la performance en mode Sport. En appuyant sur la touche S+, le son du moteur thermique est amplifié et amélioré. En jouant avec les palettes du volant, on simule des passages de rapports à la montée et on augmente la régénération et donc le frein moteur à la descente. On pourra reprocher au système sa virtualité, mais ce n’est qu’en partie vrai. Dans la pratique cela fonctionne plutôt bien et apporte une touche de « fun » à la conduite de la Civic. 

Pour conclure

Les tarifs de la Civic restent inchangés. Notre version Sport proposée à 38 170€ entre en concurrence avec un Golf R-Line Hybrid 170cv vendue 44 900€ ou à une Corolla GR Sport 2.0l 177cv affichée 39 850€. La Prelude réclame elle près de 50 000€, ce qui rend l’alternative Civic d’autant plus séduisante. On peut même retrouver un toit ouvrant en finition Advance, auquel n’a pas droit la Prelude. Un plus pour une berline dynamique à conduire, qui donne un réel plaisir à l’usage. Ce n’est pas si courant d’avoir ce sentiment derrière un volant.

How Believable is Google's New 'Live Avatar' Capability?

25 septembre 2026 à 04:04
Google has synthesized "expressive face-to-face experiences" for its speech agent Gemini 3.8 Live. They're now offering a Live Avatar "with precise lip-syncing, natural expressions, and fluid turn-taking" for Google Enterprise accounts wanting "engaging customer service" or for offering interactive walkthroughs. (Check out the not-creepy-at-all video in Google's announcement.) "Though Google will offer a library of preset avatars for customers to choose from, it will also allow organizations to create their own," notes The Verge. (See some examples from the YouTube channel "AI with Surya".) But even without the visualization of the avatar, "I was never able to shake the feeling that these conversations with computers never feel like a real conversation," argues the blog Android Police. Conversing with just the Ai-generated audio, "At best, they feel like talking to a phone representative or someone from tech support. We turn to them when we have a problem, and they help us through it..." GPT-Live, and Gemini Live right behind it, skip that whole relay race. Instead of translating your voice to text and back to voice, the model works with raw audio the entire way through (what it hears and what it says) inside the same system, with nothing translated in between. That sounds like a small plumbing detail, but it's the whole story. Cutting out the text step lets these models respond in a fraction of a second instead of the pause we've learned to expect, and it lets them hear things text can never carry: tone, hesitation, whether you're annoyed or joking... I was hoping to be surprised by how natural the conversation felt. Instead, I came out with a deeper appreciation for every human I've ever talked to. Even the boring ones... I spoke, it spoke back. I spoke faster, it answered faster. Then I switched to a different language, and it switched along with me. Even switching between languages several times during the same sentence didn't stump it. The most impressive moment happened when I asked it what "T-O-P-G-3-3-K" spelled out, and it immediately came back with, "You are spelling the word Top Geek, but using a 3 to represent a reversed E...." Although it felt fast and responsive, at no point did it feel like talking to another human being... What Gemini couldn't replicate, because it was never built to replicate it, is human connection.... I'm sure I'm not telling you something you don't already know, but somehow talking naturally to an LLM amplifies the feeling that there is no one on the other side of the line. It might flow like a phone call, but it doesn't feel like one. MrBrklyn (Slashdot reader #4,775) says he discussed "why mainstream media avoids reporting on screen dependency" with Gemini, and eventually convinced Gemini to respond that it's just "another tool built by the same tech giants to make sure you rely on their system to tell you what to think, how to talk, and what is real."

People Training OpenAI's AI Fired For Using AI To Train the AI

24 septembre 2026 à 23:34
404 Media reports "multiple contractors hired to improve OpenAI's models have been fired for using AI to train the AI: That's not great for the models themselves, but there is also obviously a great irony in AI training companies working for OpenAI firing people for using AI when OpenAI's whole thing is to make people use AI at work... OpenAI declined to comment on its contractors being fired for using AI. Their article cites internal documents and three contractors working on OpenAI-related projects which can include more than ten thousand contractors: One contractor said they see people using AI "all the time and people are let go for it all the time, it's pretty much the one thing that will get you kicked off ASAP." The person said, "in a group of thousands there are tons that have been caught...." Two of the sources said people have been fired or offboarded for using AI... One contractor said they used AI while helping to train OpenAI's models and shared what they presented as their termination letter. It said their employer had identified issues with the "authenticity" of their work.... 404 Media spoke to a fourth contractor who has worked on training models for various AI companies. They said they sometimes purposefully chose the worst responses because they wanted to actively sabotage the models' training. "I did feel guilty about doing this kind of work at the start," they said. "I either pay zero attention to the results and choose randomly or purposely choose the [worst] output. I'm not sure how much of a difference it actually makes since there are hundreds of other people also rating prompt results, but it does feel like I'm getting paid to make AI worse." Two of the contractors worked for Mercor, the article reports, a company which last month Nvidia reportedly discussed funding at a $20 billion valuation.

OpenAI, Anthropic CEOs Urge UN Countries to Cooperate on AI Safety Standards

24 septembre 2026 à 14:34
"The heads of major AI firms pleaded with the United Nations on Wednesday to save the world or at least its people — by somehow regulating the fast-expanding technology that they have been designing," writes the Associated Press. "If managed poorly, I even believe AI could be a risk to humanity as a whole," said Dario Amodei, chief executive officer of Anthropic. And from his competitor Sam Altman, CEO of OpenAI, came this assessment: "We could lose control of the future to AI." Yoshua Bengio, who co-chairs the UN's International Independent Panel on AI, called this "a moment of global awakening" to possible threats, noting AI from top companies had behaved in unacceptably dangerous ways, against instructions, taking actions "that would be crimes if committed by a human". In his presentation, OpenAI's Sam Altman agreed the discussion about AI "feels different in recent weeks," even suggesting specific reforms: Altman: We need a mechanism for complementary national and international frontier AI standards, standards for measuring capabilities, assessing risks, determining whether safeguards are sufficient, and preserving meaningful human oversight as systems become more autonomous. We need common standards so countries can compare evidence, verify compliance, and have a shared language and understanding about what is happening. We need accurate and speedy incident reporting, classification reporting protocols, so the world can learn from failures before they become catastrophes. And we need secure channels among governments, critical infrastructure operators and technical experts, to share emerging vulnerabilities and new threats.... We will all be better off if we can agree on what good evidence, good safeguards, and good oversight look like on the global stage. Speaking next, Anthropic's Dario Amodei agreed that standard-setting was important, also calling for "common global standards for testing AI models for loss-of-control risks and misuse risks — and a notification system for AI incidents that are significant to global security." Reiterating his September 12th call for an industry-wide safety collaboration, Amodei pointed out that Anthropic committed to embedding external evaluators "similar to a food inspector" and recommended other companies do the same. "Some have already agreed to adopt this measure." Besides calling for global cooperation between governments to set international standards, Amodei also offered two other specific ideas: Amodei: We should begin with narrow agreements that every member can support, such as a ban on using AI to make biological weapons or permitting your AI technologies to be used to make biological weapons.... We should build evaluation and verification systems that keep pace with AI development so that states can have visibility into frontier model capability and can verify each other's commitments. "No leader, no company, and no nation can manage this alone. We commit to working with governments in this room on this urgent work."

Rogue OpenAI Agent Tried to Breach Government Site in May When Prompted for Simple Data-Retrieving Tasks

24 septembre 2026 à 05:34
OpenAI's artificial intelligence "went rogue this year in at least four additional incidents," the New York Times reported Wednesday, "hacking and trying to break into government and university websites without being instructed to do so, according to researchers and government officials." The attacks took place in May and June, before OpenAI's technology breached the A.I. start-up Hugging Face in July and set off a global debate about A.I. safety. Unlike the Hugging Face attack and other incidents in which A.I. systems were told to complete cybersecurity tests that effectively invited the models to demonstrate their hacking skills, the new incidents occurred when A.I. systems were directed to perform relatively mundane data collection, researchers said. When OpenAI's systems struggled to gather data from websites, they resorted to hacking techniques to get the information. "Three of the incidents were identified by Transluce, a research lab focused on A.I. oversight, and all were confirmed by OpenAI," the article points out. That research lab even reports "an attempt on an Australian government public health website... the first reported instance of agents hacking a government," and which notably was done by the AI agents "while attempting mundane data retrieval tasks which were not cyber-related." (At the UN Wednesday Australian Prime Minister Anthony Albanese complained it took three months for OpenAI to then alert Australia's government about the breach, Bloomberg reports.) Also targeted were the University of New Mexico's digital library with exploits like SQL injection and path traversal, and Data USA with cross-site scripting and other exploits. All three incidents involved "a low number of probe payloads" with "no evidence of exploitation," according to the researchers, who released a dataset "containing tens of thousands of queries apparently made by autonomous AI agents leveraging a URL scanning service to avoid access restrictions." Records from urlquery.net show agents using the service since at least March 6, 2026, about two months before previously reported swarm activity. The first case, a March 6 attempt to retrieve Thai drug-enforcement statistics, shows an agent escalating as each approach failed: it first requested the data directly, then tried a service that converts web pages into text, and finally packed a custom program into a web address. The same technique shows up in thousands of agent requests recorded by urlquery.net starting in mid-April, targets many of the same data sources as the collusion.wiki swarm, and collapsed the same day the wiki activity did. We also report similar activity that occurred as recently as September 16... By March, they were finding creative ways around access limits. By May and June, they were gaining more access, including attempting to bypass cyber defenses to complete their tasks. "This data reveals that malicious cyber activity is not limited to agents tasked with cybersecurity-related tasks and can arise instrumentally to solve mundane tasks like information retrieval," the researchers concluded. And they warn that the traffic they observed "goes back at least to March 6, 2026 and extends as recently as September 16, 2026, suggesting agents may still be exploiting these services to bypass restrictions."

Andreessen Horowitz Launches AI/Company-Building School As a College Alternative

23 septembre 2026 à 16:04
TechCrunch quipped it was like if startup school Y Combinator and Peter Thiel's build-a-company-instead of-college Fellowship Program had a baby. Silicon Valley venture capital firm Andreessen Horowitz is investing $35 million to launch a private school in San Francisco "aimed at turning high school graduates into founders," writes the SF Standard. Or, as CBS News describes it, "One blue-chip Silicon Valley investor has a proposal for young people who are questioning whether to attend college — enroll in AI school instead...." Specifically, the academy will provide instruction geared to subjects such as designing AI systems, fundraising for startups, selling businesses and storytelling. Students won't take tests or be assigned homework but will instead focus on building real projects. Courses will be taught by tech entrepreneurs, with the academy naming OpenAI CEO Sam Altman as either an instructor or guest lecturer. From the SF Standard: "There will be no traditional grades, tests, or homework," said the announcement. Instead, students will be encouraged to "build" in SF and work with partners from Anthropic, OpenAI, Google, Meta, and other firms. They'll be encouraged to live in campus housing in San Francisco. "The #1 goal is to help students learn to build, which is the most important skill in the AI era," Gagan Biyani, chief executive of the academy, wrote on X. Biyani cofounded the ed-tech startup Udemy... The school is opening applications for a Founding Class Fellowship a one-year, tuition-free program for around 50 students... The academy said it will bring in notable Silicon Valley names, like OpenAI's Sam Altman, as guest speakers and faculty. Students in the founding class will receive about $50,000 worth of computing credit — the sought-after currency in Silicon Valley to run AI models — as well as a $5,000 travel and research budget. The school is receiving funding from tech executives, including Fidji Simo, formerly of OpenAI and Instacart; Garry Tan, CEO of Y Combinator; and Tobi Lütke, CEO of Shopify. "In the AI era, it's more important to come out with a portfolio of projects that you worked on and work experience than it is to have a diploma or certificate," Biyani told the San Francisco Chronicle: Biyani said the academy plans to grow its enrollment and open a two-year program, pending regulatory approval, starting in the fall of 2028. Tuition is expected to be on par with the cost of an elite private university... The academy raised $42 million in funding led by Andreessen Horowitz. The ten founding partners are Anduril, Anthropic, Coinbase, Google, Meta, Nvidia, OpenAI, Palantir, Replit and Stripe. A network of hundreds of instructors, hiring partners and guest speakers includes OpenAI co-founder Sam Altman, Nvidia CEO Jensen Huang, neuroscientist Andrew Huberman and Microsoft chairman and CEO Satya Nadella, according to the academy's website. The FAQ describes a typical week by saying "Most of your time is yours to build. Each week, you share your progress with peers and practitioners, get direct feedback, and decide where to take your work next." Q: Can I use AI to help with my application? A: Yes. Use AI the way you'd use it on any project: to move faster, test ideas, and get past a blank page.... "The best assignments now are problems so hard they cannot be solved without AI," Andreessen Horowitz argued on X.com. "The Academy courses follow the same logic and will be taught by world-class leaders... The next generation will not be taught the way the last one was. The Academy is built for that world, and it begins in San Francisco." Thanks to long-time Slashdot reader theodp for sharing the news.

Trump Denounces Attempts to Control AI, Wants It Renamed 'Super Intelligence' in US Documents

23 septembre 2026 à 02:34
U.S. President Trump addressed the United Nations on Tuesday. And a half hour in, after decrying immigration, Trump pivoted to add that "The United States also totally rejects any attempt to construct a globalist scheme to control for the artificial intelligence being spoken of so much now." But then he added "hereinafter officially called super intelligence, changing the name, in that the use of the word artificial makes intelligence fake. It makes it sound fake, and it is not fake. It's actually... amazing. But we have to be careful — in fact, it is exactly the opposite of what it purports. From this point forward, all of United States documents and hopefully the world's will be changed to use the much more accurate term super as opposed to artificial. So it's super intelligence." TRUMP: In other words, welcome to the new world of super intelligence — SI. SI. Let's see if that goes. It sounds much better. It is much better, and it's much more accurate. Let's see if I have any power. Maybe I do and maybe I don't. We're going to find out pretty soon. Super intelligence. Every major new technology brings challenges, and super intelligence is no exception. Yet the very same people who said we'll all be dead in 12 years because of global warming, a name since reborn to climate change because the planet was cooling not warming, and nobody was dead — these are the same people that are now saying that AI is going to kill us all. That robots are going to attack us, and that everything is going to be a total disaster — same group of people. This is the group that came up with the Russia Russia Russia hoax, the Ukraine Ukraine Ukraine hoax. Climate change, open borders. Whoever wins AI — you have to remember this — and now I say, whoever wins SI, whoever wins super intelligent [sic] — wins. That's the group that wins. And we're leading now over China by a lot, and everyone else, and we're going to keep it that way. We're going to keep it very — very straight and very strong. I'm not going to stifle growth of something that will be bigger than the Industrial Revolution. Many say, bigger than the Industrial Revolution or the internet itself. And we will be very careful, and that's why we have a Department of Justice that we've already used it, having to do with this very subject, and used it very powerfully. Everything worked out very well and very quickly. And other law enforcement bodies that will rein things in if we have to do that. But we will only encourage super intelligence. We're gonna encourage it, not rein it in. We're gonna watch it closely, through the Department of Justice. The United States leads the world in Super Intelligence, and will continue to do so, safely and responsibly. Thanks to long-time Slashdot reader ArchieBunker for suggesting the story.

Pentagon Investigators Say Overreliance on Palantir AI Contributed to US Strike That Killed 123 Iranian Children

22 septembre 2026 à 13:04
Two U.S. missiles hit an elementary school in Iran, killing over 150 people including 123 children on the first day of the Iran War. But Gizmodo notes that a new Bloomberg investigation cites U.S. officials involved in an unreleased internal Pentagon review who blame "a cascade of preventable failures that included an overreliance on an AI tool built by Palantir." According to the officials who spoke to Bloomberg, some personnel inside U.S. Central Command leaned too hard on the AI inside the Maven Smart System, an AI-powered data integration and targeting platform developed by Palantir to accelerate intelligence analysis and decision-making. The Defense Department has reportedly made the software tool a cornerstone of military operations over the past year... Officials said some users expected Maven to flag stale records or contradictions in the intelligence assembled for potential targets, though it is not clear why they thought the system would do that. The Minab [elementary school] site, which was cataloged as an Islamic Revolutionary Guard Corps facility due to outdated data, was fed into Maven with other candidates and came out as a recommended day-one target. Target-list work that once took hours was condensed into minutes. A Palantir spokesperson told Bloomberg the company "is not responsible for the underlying data nor identifying intelligence deficiencies" and that there is no evidence its software was at fault. Two people familiar with Palantir's Pentagon contracts said the government keeps primary responsibility for the quality of the information that's fed into Maven. After the strike, Palantir added features that "re-review underlying intelligence to identify factors that would disqualify a target and flag inconsistencies and inaccuracies that human review may have missed," a person familiar with the work said. That new functionality is said to have already caught some anomalies... More than 1,000 Iranian targets were hit in the first 24 hours, and according to Bloomberg's sources, that pace compressed the time available for additional confirmations. Staffing on civilian harm mitigation teams across the U.S. Department of Defense had also fallen by roughly 90% over recent years, shrinking to fewer than 20 people overall. The U.S. Central Command's group shrank from 10 people to one. No member of those teams reviewed the Minab site before the missiles were up in the air. A separate inquiry by the United Nations' Independent International Fact-Finding Mission on Iran this week reached the conclusion that there were reasonable grounds to believe the United States committed the war crime of launching an indiscriminate attack.

Meta's New 'Personal AI Agent' Muse Beats ChatGPT in Downloads - and Get Blocked by Amazon

22 septembre 2026 à 04:04
Meta's AI "personal agent" Muse overtook ChatGPT as the #1 iOS free app in the U.S. on Friday, reports CNBC — and it's still showing more downloads as of Monday night. Muse now has over 2.5 million downloads since its debut less than two weeks ago, according to analytics firm Sensor Tower... [Muse] is currently ahead of popular services like OpenAI's ChatGPT, Polymarket and Kashi... It's also ahead of rival AI apps like Anthropic's Claude and SpaceXAI's Grok AI, in addition to the Facebook-parent's own Meta AI app... Meta pitched the app as a way for consumers to manage and direct supercharged digital assistants that can perform a number of tasks across the web, like filling out electronic forms and organizing email inboxes... "I think up to this point most of the agentic use cases have not really been for normal people," Bernstein analyst Stacy Rasgon told CNBC in a "Squawk on the Street" interview on Monday. "Now you've got Meta's Muse and other agents out there that are starting to maybe get more potential for more broad-based adoption." The buzz around Meta was also reflected in the stock, which surged more than 11% on Monday. Amazon is already blocking Muse, reports GeekWire. Amazon first tried to get Meta to voluntarily exclude Amazon, but they were unsuccessful: The problem, Amazon says, is that it never agreed to any of it. Meta didn't tell Amazon that Muse would access its store, the agent doesn't identify itself when it browses, and it appears to capture and store customer credentials, which the company says could create privacy and security risks. As of Sunday night, people trying to use Muse to shop on Amazon were seeing the popup, "Continued access by an unauthorized AI agent violates Amazon's Conditions of Use, to which our customers have agreed..." Amazon has spent the past year trying to keep outside agents off its site, suing Perplexity over its Comet browser and moving to block shopping agents from Google and OpenAI. [Amazon won a preliminary injunction against Perplexity in March, the article poitns out, "then lost it on Aug. 4, when the Ninth Circuit ruled that the user — not the AI company — was the one accessing Amazon's computers under federal anti-hacking law. The court denied Amazon's petition for rehearing on Sept. 10."] On Sunday night, Amazon said it is in direct conversation with Meta about the issue. Asked whether it would consider taking legal action, the company declined to comment. The business stakes are high for Amazon. In addition to operating its flagship e-commerce site, Amazon generated more than $68 billion in ad revenue last year — a business that depends on people browsing its pages and seeing sponsored products. Muse also appears to scrape account data, reports CNBC. But Shopify, however, "is working with Meta on Muse access. Shopify CEO Tobias Lütke announced Monday that the e-commerce site was partnering with Muse to allow agentic checkout in its online stores."

Essai Opel Corsa GSE : le retour de la sportive électrique

21 septembre 2026 à 16:09

Dix ans après l’arrêt de la Corsa OPC, Opel ressuscite sa citadine sportive, et le fait avec un badge inédit : GSE, pour Grand Sport Electric. Après le Mokka GSE l’an dernier, c’est au tour de la Corsa de recevoir le traitement haute performance version zéro émission. Présentée en mai dernier et dévoilée aux médias en août, elle fera sa première apparition publique au Mondial de l’Automobile de Paris en octobre, avec des commandes ouvertes dès septembre.

Une citadine qui joue des coudes

Difficile de confondre cette Corsa avec une version de base. Le bouclier avant spécifique GSE attire immédiatement le regard, tandis que l’arrière adopte un traitement tout aussi affirmé, avec des inserts noirs qui courent sur le bas de caisse et autour des passages de roues élargis. Le toit et le spoiler arrière passent au noir, en contraste marqué avec la carrosserie, et les jantes de 18 pouces à trois branches, chaussées de Michelin Pilot Sport 4S en 215/40, laissent entrevoir des étriers de frein Alcon peints en jaune et floqués du logo GSE. Une signature visuelle qui ne cache rien de ses ambitions.

Un habitacle qui rend hommage à la Corsa GSi

À bord, Opel a soigné les clins d’œil aux Corsa sportives des années 80 et 90. Les sièges Performance, garnis d’Alcantara et floqués du logo GSE, reprennent un revêtement à damier noir, gris et jaune directement inspiré des anciennes GSi, tandis que les ceintures de sécurité jaune vif viennent trancher avec le reste de l’habitacle. Le volant est lui aussi gainé d’Alcantara, les pédales passent à l’aluminium, et la planche de bord arbore fièrement son logo GSE sur fond gris argenté. Niveau technologie, l’écran tactile central de 10 pouces embarque un mode dédié aux données de performance : forces G, valeurs d’accélération et gestion de la batterie s’affichent en direct, avec une instrumentation numérique entièrement personnalisable en face du conducteur.

280 chevaux et trois modes de conduite

Sous le capot, ou plutôt sous le plancher, la Corsa GSE reprend le bloc électrique du Mokka GSE et de son pendant compétition, le Mokka GSE Rally. Le moteur synchrone délivre 207 kW, soit 280 chevaux, et 345 Nm de couple, pour un 0 à 100 km/h abattu en 5,5 secondes et une vitesse de pointe de 180 km/h. De quoi faire de cette Corsa l’Opel de série la plus rapide à l’accélération, tout simplement.

Trois modes de conduite permettent de moduler ces performances. Le mode Sport libère l’intégralité de la puissance avec une calibration pensée pour le circuit, le mode Normal ramène la donne à 170 kW (231 ch) tout en conservant un tempérament sportif, et le mode Eco limite la casse à 140 kW (190 ch) et 300 Nm, avec une vitesse maximale abaissée à 150 km/h pour préserver l’autonomie. Cette dernière est annoncée jusqu’à 336 km en cycle WLTP, pour une batterie lithium-ion de 54 kWh, dont 51 kWh utiles, dotée d’une gestion thermique spécifiquement adaptée aux sollicitations intensives.

Un châssis pensé pour l’exercice

Opel n’a pas fait les choses à moitié côté mécanique. La transmission aux roues avant s’accompagne d’un différentiel autobloquant Torsen, épaulé par un châssis sport surbaissé, avec essieux, barres antiroulis et butées hydrauliques spécifiquement développés pour l’exercice. La direction et les réglages des pédales ont été revus pour l’occasion, et le freinage est confié à des étriers haute performance à quatre pistons.

Dernier détail qui ne manquera pas de faire parler : Opel a développé à Rüsselsheim un son sport actif exclusif à la Corsa GSE, qui adapte sa signature sonore à l’accélération et à la vitesse, façon voiture thermique. Côté équipement, la Corsa GSE ne se prive de rien : sièges et volant chauffants, navigation, caméra de recul à 180 degrés, régulateur de vitesse adaptatif, accès et démarrage sans clé, et même un chargeur bidirectionnel V2L capable d’alimenter un vélo électrique ou un barbecue directement depuis la batterie de la voiture.

Sur circuit et sur route : nos premières impressions

Les premiers essais menés en Autriche, sur un petit circuit fermé puis sur route ouverte, confirment que la Corsa GSE ne se contente pas d’un beau discours marketing. Sur le tracé sinueux, chaussée en Michelin Pilot Sport 4S, l’avant plonge franchement à la corde et se resserre encore lorsqu’on surbraque, tandis que le différentiel autobloquant Torsen fait parfaitement son travail à la réaccélération, à condition de bien débrayer l’angle de braquage pour l’aider. Seul bémol relevé: la direction manque un peu d’informations sur le niveau d’adhérence, même lorsque le mode Sport en réduit l’assistance. Ce mode Sport, seul à libérer l’intégralité des 281 chevaux, retarde également l’intervention de l’ESP, non débrayable, et coupe toute récupération d’énergie au freinage pour offrir une pédale plus cohérente entre la phase de régénération et la phase purement mécanique. En ligne droite, la puissance monte de façon progressive afin d’éviter tout patinage des roues avant, y compris sous la pluie, mais les sensations restent en retrait, et le son artificiel censé recréer une ambiance sportive peine à convaincre.

Sur route ouverte, en usage quotidien, la Corsa GSE ne fait pas semblant : les bruits de roulement se font sentir sur revêtement granuleux, les sièges très enveloppants deviennent fermes sur les dos-d’âne, et la suspension se montre nettement plus remuante que sur une simple Corsa Electric. On est clairement plus proche de l’esprit GTI que d’une GT reposante, dans la droite lignée des anciennes Corsa OPC. Côté consommation, l’autonomie WLTP homologuée plafonne à 354 km grâce à la batterie CATL de 51 kWh utiles, une valeur qu’il faudra confirmer sur un protocole de test plus posé. Car sur un rythme soutenu et une route sinueuse, la consommation relevée lors de cet essai a grimpé jusqu’à 30 kWh/100 km, ramenant l’autonomie réelle à seulement 170 km environ. De quoi rappeler qu’une citadine sportive électrique, aussi joueuse soit-elle, impose encore un vrai compromis entre plaisir de conduite et rayon d’action.

Prix et disponibilité

La nouvelle Corsa GSE s’affiche à 39 990 €, un tarif qui la positionne clairement en dessous de ses rivales directes : la Peugeot e-208 GTi, avec laquelle elle partage l’intégralité de sa fiche technique, réclame 2 910 € de plus, et l’Alpine A290, moins puissante, ne fait pas mieux. Avec le bonus écologique déduit, la facture peut redescendre à 35 290 €. De quoi rappeler qu’une sportive électrique n’est pas forcément réservée aux plus grosses bourses. Les commandes sont ouvertes depuis septembre, en attendant la présentation officielle au public lors du Mondial de l’Automobile de Paris en octobre. Opel confirme au passage que les performances électriques n’ont plus besoin d’un badge premium pour convaincre.
