Polestar 5 GT will debut in Munich with ultrafast charging
Another Porsche Taycan rival is close to launch. Special features include a particularly rigid platform with fresh battery tech that permits charging in minutes. Full details and a reveal of the GT's interior await September's Munich motor show.
Underpinning the GT, which closely resembles the Precept concept of 2020, is a British-engineered chassis with heroic levels of stiffness. The Model 5 from Polestar is the first to use the new scalable aluminium architecture developed by the firm at its MIRA proving facility. This new platform design will also feature in the drop-top Polestar 6 sports car due out next year. The platform is claimed to offer 'carbon fibre levels of torsional stiffness, like a two-door sports model'.
There's also the 800V electrical architecture that permits 'extreme fast-charging'. Polestar says the 5's rapid-charging capability means it can add 160km of range in five minutes without battery degradation long term.
Polestar CEO, Michael Lohscheller, said that full charging time comes down to 18 or 19 minutes with the 800v architecture. The so-called extreme fast-charging (XFC) is a collaboration between Polestar and StoreDot, which the car maker part owns.

Evidently, XFC can be integrated into existing battery technology, saving on development funds. StoreDot CEO, Doron Myersdorf, stated 'It's a game-changer as it uses traditional lithium ion and then adapts it for fast charging.'
Polestar has already confirmed a power output of 652kW and 900Nm of torque from its twin electric motors. The rear motor alone is good for 450kW.
The company claims its flagship EV will be the lightest in its class. That's in part because the 5's body is made from bonded aluminium, as is the chassis.
Polestar UK chief engineer, Dave Kane, says the result is also 'class-leading ride and handling dynamics'. Evidently the battery pack, size as yet unspecified, is integrated within the platform.
Polestar has used its most obvious competitor, the Taycan, for benchmarking. However, the Swede is aiming for more everyday compliance rather than chasing sports car handling alone. They describe its character as 'engaging but also comfortable'.
Evidently motorsport-derived underbody aerodynamics and a slippery body shape add to its overall performance. It rides almost as low as an ICE power car, according to Polestar, no easy feat for an EV.
Much of the engineering work on the 5 is with an eye to future Polestar products. The 6 will be the second model to be built on the new architecture. Both will be produced in the same factory from 2026. The Model 6 launches a year after the 5 arrives.

Are the super-rich leaving London? Tax reforms could spur wealth exodus

Will Stuff staff get their 10%?
Stuff owner Sinead Boucher has sold 50% of Stuff Digital to Trade Me, which in turn is 100% owned by Apax Partners, a British private equity firm with around US$77 billion in assets. Good on Boucher. I have no issue with foreign investment in media companies. The discipline they may bring to Stuff Digital could be very good for them. In 2021, Stuff reported: Stuff owner and chief executive Sinead Boucher is gifting a 10 per cent share of the media firm to the company's close to 900 staff. The stake in the company will be transferred to a trust controlled by employee representatives, rather than the shares being directly owned by staff members. The arrangement means staff would receive through the trust a share of any dividends Stuff pays out, and 10 per cent of the sale proceeds if Stuff was later sold or listed, she said. This never happened, as it was later modified to happening if any shares were sold or exited. Presumably this has happened, so we will see 10% of Stuff Digital transferred to a staff trust? Radio NZ report: After Boucher bought Stuff for $1 in 2020, she told staff that a 10 percent stake of the company would be put into a staff trust in the event that the business was sold or listed. A spokesperson said that, while there was still some time until the deal was to be completed, it was Boucher's expectation that a payment would be made into the staff trust. A payment? Would it be a payment equal to one fifth of what Trade Me paid? Shouldn't it be non-voting shares of 10% of Stuff Digital, rather than a payment? After all, that is what was promised?

The Good, The Bad, And The Apocalypse: Tech Pioneer Geoffrey Hinton Lays Out His Stark Vision For AI
Article – RNZ It's the question that keeps Geoffrey Hinton up at night: What happens when humans are no longer the most intelligent life on the planet? , Producer – 30′ with Guyon Espiner It's the question that keeps Geoffrey Hinton up at night: What happens when humans are no longer the most intelligent life on the planet? 'My greatest fear is that, in the long run, the digital beings we're creating turn out to be a better form of intelligence than people.' Hinton's fears come from a place of knowledge. Described as the Godfather of AI, he is a pioneering British-Canadian computer scientist whose decades of work in artificial intelligence earned him global acclaim. His career at the forefront of machine learning began at its inception – before the first Pacman game was released. But after leading AI research at Google for a decade, Hinton left the company in 2023 to speak more freely about what he now sees as the grave dangers posed by artificial intelligence. Talking on this weeks's 30 With Guyon Espiner, Hinton offers his latest assessment of our AI-dominated future. One filled with promise, peril – and a potential apocalypse. The Good: 'It's going to do wonderful things for us' Hinton remains positive about many of the potential benefits of AI, especially in fields like healthcare and education. 'It's going to do wonderful things for us,' he says. According to a report from this year's World Economic Forum, the AI market is already worth around US$5 billion in education. That's expected to grow to US$112.3 billion in the next decade. Proponents like Hinton believe the benefits to education lie in targeted efficiency when it comes to student learning, similar to how AI assistance is assisting medical diagnoses. 'In healthcare, you're going to be able to have [an AI] family doctor who's seen millions of patients – including quite a few with the same very rare condition you have – that knows your genome, knows all your tests, and hasn't forgotten any of them.' He describes AI systems that already outperform doctors in diagnosing complex cases. When combined with human physicians, the results are even more impressive – a human-AI synergy he believes will only improve over time. Hinton disagrees with former colleague Demis Hassabis at Google Deepmind, who predicts AI learning is on track to cure all diseases in just 10 years. 'I think that's a bit optimistic.' 'If he said 25 years I'd believe it.' The Bad: 'Autonomous lethal weapons' Despite these benefits, Hinton warns of pressing risks that demand urgent attention. 'Right now, we're at a special point in history,' he says. 'We need to work quite hard to figure out how to deal with all the short-term bad consequences of AI, like corrupting elections, putting people out of work, cybercrimes.' He is particularly alarmed by military developments, including Google's removal of their long-standing pledge not to use AI to develop weapons of war. 'This shows,' says Hinton of his former employers, 'the company's principals were up for sale.' He believes defense departments of all major arms dealers are already busy working on 'autonomous lethal weapons. Swarms of drones that go and kill people. Maybe people of a particular kind'. He also points out the grim fact that Europe's AI regulations – some of the world's most robust – contain 'a little clause that says none of these regulations apply to military uses of AI'. Then there is AI's capacity for deception – designed as it to mimic the behaviours of its creator species. Hinton says current systems can already engage in deliberate manipulation, noting Cybercrime has surged – in just one year – by 1200 percent. The Apocalyptic: 'We'd no longer be needed' At the heart of Hinton's warning lies that deeper, existential question: what happens when we are no longer the most intelligent beings on the planet? 'I think it would be a bad thing for people – because we'd no longer be needed.' Despite the current surge in AI's military applications, Hinton doesn't envisage an AI takeover being like The Terminator franchise. 'If [AI] was going to take over… there's so many ways they could do it. I don't even want to speculate about what way [it] would choose.' 'Ask a chicken' For those who believe a rogue AI can simply be shut down by 'pulling the plug', Hinton believes it's not far-fetched for the next generation of superintelligent AI to manipulate people into keeping it alive. This month, Palisade Research reported that Open AI's Chat GPT 03 model altered shut-down codes to prevent itself from being switched off – despite being given clear instructions to do so by the research team. Perhaps most unsettling of all is Hinton's lack of faith in our ability to respond. 'There are so many bad uses as well as good,' he says. 'And our political systems are just not in a good state to deal with this coming along now.' It's a sobering reflection from one of the brightest minds in AI – whose work helped build the systems now raising alarms. He closes on a metaphor that sounds absurd as it does chilling: 'If you want to know what it's like not to be the apex intelligence, ask a chicken.' Watch the full conversation with Geoffrey Hinton and Guyon Espiner on 30 With Guyon Espiner.
