Here’s what we learned driving Audi’s new Q6 and SQ6 electric SUVs
Audi provided flights from Washington, DC, to San Francisco and accommodation so Ars could drive the Q6 and SQ6. Ars does not accept paid editorial content.
HEALDSBURG, Calif.—Earlier this summer, Ars got its first drive of Audi's new Q6 e-tron on some very wet roads in Spain. Then, we were driving pre-production Q6s in Euro-spec. Now, the electric SUV is on sale in the US, with more power in the base model and six months more refinement for its software. But the venue change did not bring a change of weather—heavy rain was the order of the day, making me wonder if Audi is building its new electric vehicle on the site of an ancient rain god's temple?
Of all its rivals, Audi appears to have settled into a nomenclature for its vehicles that at least makes a little sense. Odd numbers are for internal combustion engines, even numbers for EVs, although it also appends "e-tron" on the end to make that entirely clear... and give francophones something to snicker about. (Yes, the e-tron GT does not fit into this schema, but nobody's perfect.)
The Q6 e-tron is also the most advanced EV to wear Audi's four rings. Built on a new architecture called PPE (premium platform electric), at its heart is an 800 V powertrain with a 100 kWh (94.4 kWh useable) lithium-ion battery pack that powers a permanently excited synchronous motor driving the rear wheels, and in the case of the quattro versions, an asynchronous motor. The electric motors have 30 percent less energy consumption than those used in the Q8 e-tron, and are smaller and lighter.

The New Glenn rocket’s seven powerful engines may light up as soon as today
In a widely anticipated test, Blue Origin may ignite the seven main engines on its New Glenn rocket as soon as Thursday at Launch Complex-36 in Florida.
This is the final test the company must complete before verifying the massive rocket is ready for its debut flight, and it is the most dynamic. This will be the first time Blue Origin has ever test-fired the BE-7 engines altogether, in a final rehearsal before launch.
The company did not respond immediately to a request for comment, but the imminent nature of the test was confirmed by a NASA official.

Journal that published faulty black plastic study removed from science index
The publisher of a high-profile, now-corrected study on black plastics has been removed from a critical index of academic journals amid questions about quality criteria, according to a report by Retraction Watch.
On December 16, Clarivate—a scholarly publication analytics company—removed the journal Chemosphere from its platform, the Web of Science, which is a key index for academic journals. The indexing platform tracks citations and calculates journal "impact factors," a proxy for relevance in its field. It's a critical metric not only for the journals but for the academic authors of the journal's articles, who use the score in their pursuit of promotions and research funding.
To be included in the Web of Science, Clarivate requires journals to follow editorial quality criteria. According to Retraction Watch, Chemosphere has retracted eight articles this month and published 60 expressions of concern since April.

A new, uncensored AI video model may spark a new AI hobbyist movement
The AI-generated video scene has been hopping this year (or twirling wildly, as the case may be). This past week alone we've seen releases or announcements of OpenAI's Sora, Pika AI's Pika 2, Google's Veo 2, and Minimax's video-01-live. It's frankly hard to keep up, and even tougher to test them all. But recently, we put a new open-weights AI video synthesis model, Tencent's HunyuanVideo, to the test—and it's surprisingly capable for being a "free" model.
Unlike the aforementioned models, HunyuanVideo's neural network weights are openly distributed, which means they can be run locally under the right circumstances (people have already demonstrated it on a consumer 24 GB VRAM GPU) and it can be fine-tuned or used with LoRAs to teach it new concepts.
Notably, a few Chinese companies have been at the forefront of AI video for most of this year, and some experts speculate that the reason is less reticence to train on copyrighted materials, use images and names of famous celebrities, and incorporate some uncensored video sources. As we saw with Stable Diffusion 3's mangled release, including nudity or pornography in training data may allow these models achieve better results by providing more information about human bodies. HunyuanVideo notably allows uncensored outputs, so unlike the commercial video models out there, it can generate videos of anatomically realistic, nude humans.

Krypto steals the show in Superman teaser
David Corenswet stars in James Gunn's Superman reboot.
The Internet has been buzzing the last few days about James Gunn's Superman reboot slated for release next year. The studio released a "motion poster" earlier this week set to a moody cover of John Williams' "Superman March," as well as a teaser for a teaser for the film. That teaser just dropped.
Clearly, given all the buildup, what director James Gunn wants for Christmas is for everyone to get excited over his Superman movie. And you know what? It kinda worked, especially since Superman's dog Krypto makes an adorably welcome appearance.
Gunn describes his take as less of an origin story and more of a journey, with Superman struggling to reconcile his Kryptonian heritage and aristocratic origins with his small-town, adoptive human family. Gunn tapped David Corenswet to play Clark Kent/Superman, at 25 a bit more established than the young cub reporter of Smallville, for instance. Rachel Brosnahan plays Lois Lane, Skyler Gisondo plays Jimmy Olsen, and Nicholas Holt is arch-nemesis Lex Luther. (Holt's son shaved his head for the role.) Luther's sidekicks are played by Sara Sampaio as Eve Teschmacher and Terence Rosemore as Otis.

Amazon faces holiday strike after refusing to bargain with warehouse workers
Amazon workers at seven warehouses walked out Thursday morning, launching a strike ahead of the holidays after Amazon failed to meet a bargaining deadline set by the Teamsters union representing the workers.
In a press release, Teamsters declared it "the largest strike against Amazon in US history." Teamsters general president, Sean O'Brien, warned shoppers of potential delays, saying "you can blame Amazon’s insatiable greed."
"We gave Amazon a clear deadline to come to the table and do right by our members. They ignored it," O’Brien said. "These greedy executives had every chance to show decency and respect for the people who make their obscene profits possible. Instead, they’ve pushed workers to the limit and now they’re paying the price. This strike is on them."

Solving renewable energy’s sticky storage problem
When the Sun is blazing and the wind is blowing, Germany’s solar and wind power plants swing into high gear. For nine days in July 2023, renewables produced more than 70 percent of the electricity generated in the country; there are times when wind turbines even need to be turned off to avoid overloading the grid.
But on other days, clouds mute solar energy down to a flicker and wind turbines languish. For nearly a week in January 2023, renewable energy generation fell to less than 30 percent of the nation’s total, and gas-, oil- and coal-powered plants revved up to pick up the slack.
Germans call these periods Dunkelflauten, meaning “dark doldrums,” and they can last for a week or longer. They’re a major concern for doldrum-afflicted places like Germany and parts of the United States as nations increasingly push renewable-energy development. Solar and wind combined contribute 40 percent of overall energy generation in Germany and 15 percent in the US and, as of December 2024, both countries have goals of becoming 100 percent clean-energy-powered by 2035.

Amazon’s RTO delays exemplify why workers get so mad about mandates
Amazon announced in September that it will require workers to be in the office five days a week starting in January. Employee backlash ensued, not just because return-to-office (RTO) mandates can be unpopular but also because Amazon is using some of the worst strategies for issuing RTO mandates.
Ahead of the mandate, Amazon had been letting many employees work remotely for two days a week, with a smaller number of workers being totally remote. But despite saying that employees would have to commute five days per week, the conglomerate doesn’t have enough office space to accommodate over 350,000 employees. Personnel in “at least seven cities,” including Phoenix and Austin, Texas, have had their RTO dates delayed until after January, Bloomberg reported today, citing “people familiar with the situation." Employees in Dallas won’t have enough space until March or April, and an office in New York City won’t have sufficient space until May, per Bloomberg's sources.
RTO dates are also delayed in Atlanta, Houston, and Nashville, Tennessee, Business Insider reported this week, citing “internal Amazon notifications.”

$2 per megabyte: AT&T mistakenly charged customer $6,223 for 3.1GB of data
An AT&T customer who switched to the company's FirstNet service for first responders got quite the shock when his bill came in at $6,223.60, instead of the roughly $260 that his four-line plan previously cost each month.
The Texas man described his experience in a now-deleted Reddit post three days ago, saying he hadn't been able to get the obviously incorrect bill reversed despite calling AT&T and going to an AT&T store in Dallas. The case drew plenty of attention and the bill was finally wiped out several days after the customer contacted the AT&T president's office.
The customer said he received the billing email on December 11. An automatic payment was scheduled for December 15, but he canceled the autopay before the money was charged. The whole mess took a week to straighten out.

Louisiana resident in critical condition with H5N1 bird flu
The Louisiana resident infected with H5N1 bird flu is hospitalized in critical condition and suffering from severe respiratory symptoms, the Louisiana health department revealed Wednesday.
The health department had reported the presumptive positive case on Friday and noted the person was hospitalized, as Ars reported. But a spokesperson had, at the time, declined to provide Ars with the patient's condition or further details, citing patient confidentiality and an ongoing public health investigation.
This morning, the Centers for Disease Control and Prevention announced that it had confirmed the state's H5N1 testing and determined that the case "marks the first instance of severe illness linked to the virus in the United States."

The Backbone One would be an ideal game controller—if the iPhone had more games
In theory, it ought to be as good a time as ever to be a gamer on the iPhone.
Classic console emulators have rolled out to the platform for the first time, and they work great. There are strong libraries of non-skeezy mobile games on Apple Arcade and Netflix Games, streaming via Xbox and PlayStation services is continuing apace, and there are even a few AAA console games now running natively on the platform, like Assassin's Creed and Resident Evil titles.
Some of those games need a traditional, dual-stick game controller to work well, though, and Apple bafflingly offers no first-party solution for this.

Arm says it’s losing $50M a year in revenue from Qualcomm’s Snapdragon X Elite SoCs
Arm and Qualcomm's dispute over Qualcomm's Snapdragon X Elite chips is continuing in court this week, with executives from each company taking the stand and attempting to downplay the accusations from the other side.
If you haven't been following along, the crux of the issue is Qualcomm's purchase of a chip design firm called Nuvia in 2021. Nuvia was originally founded by ex-Apple chip designers to create high-performance Arm chips for servers, but Qualcomm took an interest in Nuvia's work and acquired the company to help it create high-end Snapdragon processors for consumer PCs instead. Arm claims that this was a violation of its licensing agreements with Nuvia and is seeking to have all chips based on Nuvia technology destroyed.
According to Reuters, Arm CEO Rene Haas testified this week that the Nuvia acquisition is depriving Arm of about $50 million a year, on top of the roughly $300 million a year in fees that Qualcomm already pays Arm to use its instruction set and some elements of its chip designs. This is because Qualcomm pays Arm lower royalty rates than Nuvia had agreed to pay when it was still an independent company.

Supreme Court to decide if TikTok should be banned or sold
On Wednesday, the Supreme Court confirmed it would review whether a federal law that could ban or force a sale of TikTok is unconstitutional.
The announcement came just one day after TikTok and its owner ByteDance petitioned SCOTUS for a temporary injunction to halt the ban until the high court could consider what TikTok claimed is "a massive and unprecedented speech restriction" ahead of a change in US presidential administrations.
“We’re pleased with today’s Supreme Court order," TikTok said in a statement. "We believe the Court will find the TikTok ban unconstitutional so the over 170 million Americans on our platform can continue to exercise their free speech rights.”

Call ChatGPT from any phone with OpenAI’s new 1-800 voice service
On Wednesday, OpenAI launched a 1-800-CHATGPT (1-800-242-8478) telephone number that anyone in the US can call to talk to ChatGPT via voice chat for up to 15 minutes for free. The company also says that people outside the US can send text messages to the same number for free using WhatsApp.
Upon calling, users hear a voice say, "Hello again, it's ChatGPT, an AI assistant. Our conversation may be reviewed for safety. How can I help you?" Callers can ask ChatGPT anything they would normally ask the AI assistant and have a live, interactive conversation.
During a livestream demo of "Calling with ChatGPT" during Day 10 of "12 Days of OpenAI," OpenAI employees demonstrated several examples of the telephone-based voice chat in action, asking ChatGPT to identify a distinctive house in California and for help in translating a message into Spanish for a friend. For fun, they showed calls from an iPhone, a flip phone, and a vintage rotary phone.

TP-Link faces possible US ban as hijacked routers fuel Chinese attacks
US government authorities are reportedly investigating whether to ban TP-Link wireless routers, which have been targeted in some high-profile attacks linked to the Chinese government. TP-Link, which was founded in China in 1996 and said it relocated its headquarters to the US in October this year, has racked up significant market share in US homes and businesses.
US authorities are investigating whether TP-Link "poses a national-security risk and are considering banning the devices," The Wall Street Journal reported today. The WSJ notes that TP-Link is "the top choice on Amazon.com, and powers Internet communications for the Defense Department and other federal government agencies."

Z-Wave Long Range and its mile-long capabilities will arrive next year
Z-Wave can be a very robust automation network, free from the complications and fragility of Wi-Fi and Bluetooth. Just how robust, you ask? More than a mile long, under the right circumstances, as hardware soon to hit the market promises.
All claims of radio distances should be taken with amounts of salt unhealthy for consumption. What can be accomplished across an empty field is not the same as what can be done through buildings, interference, and scatter. But Z-Wave Long Range (or Z-Wave LR), operating "in long range mode at full power," can hit 1.5 miles, according to the Z-Wave Alliance, presuming you've got the right star-shaped hub network.
By using a star network topology instead of a more traditional mesh, Z-Wave LR reduces the need for hubs and repeaters, relying instead on a central hub. It can be more reliable for larger commercial spaces, security setups, and bigger homes, and also more power efficient. Devices automatically adjust their signal strength while on Z-Wave networks, extending the battery life of a single coin cell up to 10 years—again, under best-case circumstances. If you're really a glutton for punishment, you can fit up to 4,000 devices on a network running Z-Wave LR, because LR can co-exist on the same network as standard Z-Wave meshes.

The $700 price tag isn’t hurting PS5 Pro’s early sales
When Sony revealed the PlayStation 5 Pro a few months ago, some wondered just how many people would be willing to spend $700 for a marginal upgrade to the already quite powerful graphical performance of the PS5. Now, initial sales reports suggest there's still a substantial portion of the console market that's willing to shell out serious money for top-of-the-line console graphics.
Circana analyst Matt Piscatella shared on Bluesky this morning that the PS5 Pro accounted for a full 19 percent of US PS5 sales in its launch month of November. That sales ratio puts initial upgrade interest in the PS5 Pro roughly in line with lifetime interest in the PS4 Pro, which recent reports suggest was responsible for about 20 percent of all PS4 sales following its launch in 2016.
That US sales ratio also lines up with international sales reports for the PS5 Pro launch. In the UK, GfK ChartTrack reports that the PS5 Pro was responsible for 26 percent of all console sales for November. And in Japan, Famitsu sales data suggests the PS5 Pro was responsible for a full 63 percent of the PS5's November sales after selling an impressive 78,000 units in its launch week alone.

EPA lets California set its own stricter emissions standards until 2035
Today, the US Environmental Protection Agency granted a pair of waivers to California, allowing the Golden State to continue regulating vehicle-caused air pollution within its borders. The first is for the California Air Resources Board's Advanced Clean Cars II regulations, which apply to light- and medium-duty vehicles like passenger cars, SUVs, and smaller trucks. The second waiver is for regulations that control the amount of nitrogen oxides (NOx) that can be emitted by heavy-duty vehicles as well as off-road vehicles.
The Clean Air Act allows states to apply for a waiver from the EPA to set their own emissions standards in cases where the federal regulations are insufficient to prevent deleterious pollution. The state applied for the latest waivers late in 2023, and after a public comment period and then a review by the agency, the EPA decided to approve them.
"California has longstanding authority to request waivers from EPA to protect its residents from dangerous air pollution coming from mobile sources like cars and trucks," said EPA Administrator Michael Regan. "Today's actions follow through on EPA's commitment to partner with states to reduce emissions and act on the threat of climate change."

GM and ChargePoint will deploy hundreds of “Omni Port” chargers in 2025
General Motors might have scaled back its electric vehicle ambitions in favor of more hybrids, but it's still accelerating its plans to build out EV charging infrastructure. Today, together with ChargePoint, GM revealed that it will deploy "hundreds" of new DC fast chargers under the GM Energy brand in 2025.
"The transition to electric mobility continues to be driven by leaders such as General Motors offering innovative EVs and committing to make chargers as ubiquitous as possible," said Rick Wilmer, CEO of ChargePoint. "Our collaboration with GM represents a significant investment in the infrastructure to enable fast and easy charging for all. Together, ChargePoint and GM will deliver a seamless fast charging experience via reliable charging hardware managed by our industry-leading software platform."
Many (but not all) of the new chargers will be capable of delivering up to 500 kW, a higher power level than any EV currently on the market is able to charge. Many of the chargers will also feature ChargePoint's "Omni Port," which has both CCS1 and NACS (J3400) plugs, allowing almost all EV drivers to make use of them. (Sorry, Nissan Leaf owners.)

Reminder: Donate to win swag in our annual Charity Drive sweepstakes
If you've been too busy fixing your video drivers to take part in this year's Ars Technica Charity Drive sweepstakes, don't worry. You still have time to donate to a good cause and get a chance to win your share of over $4,000 worth of swag (no purchase necessary to win).
In the first week or so of the drive, nearly 180 readers have contributed almost $16,000 to either the Electronic Frontier Foundation or Child's Play as part of the charity drive (Child's Play is barely hanging on to a small donation lead at the moment). That's a long way off from 2020's record haul of over $58,000, but there's still plenty of time until the Charity Drive wraps up on Thursday, January 2, 2025.
That doesn't mean you should put your donation off, though. Do yourself and the charities involved a favor and give now while you're thinking about it.
