GM Volt to get regular software-style updates

'Blast, I've bricked the gearbox'


'Leccy Tech General Motors has given some insights into how it plans to squeeze every last mile from the Chevrolet Volt's battery back - and how it hopes to develop the model.

According to Frank Weber, “vehicle line executive” for the Volt's Voltec propulsion system, it's all about “maximizing its mechanical, electrical and thermal efficiency. From the Voltec propulsion system down to individual components such as tires or sound systems”, he said during a presentation at the Chicago Motor Show.

GM Volt/Ampera: software-style updates programme

To start with, the Volt - to be called the Ampera over here - will come with Goodyear Assurance Fuel Max energy-efficient tyres which, according to GM, will alone add a whole mile to the Volt's battery-only driving range.

Goodyear claims to have “packed performance features into the tyre to enhance the Volt's fun-to-drive characteristics”. Hopefully, that means a move away from the usual feature of economy oriented tyres being about as much fun to drive on as a set of 1950 cross-plies.

The Volt will also see the début of a Bose sound system that's also heralded as "energy efficient" and said to be 30 per cent smaller, 40 per cent lighter and to use half as much energy as conventional Bose sound systems do.

More interestingly, Weber told the audience that the Volt will see important and major “updates” during its production run. "This is almost like getting software updates into your car... this is not a mechanical world... you get updates, improvements much more rapidly."

Dunno, mate - I think you need Service Pack 3, but it's not out of beta yet

Much as we like the idea of software updates for our cars – assuming they don't take two hours to load, only to brick it or disable the stereo and gearbox – we are taking this to mean that rather than be launched, then face-lifted, then replaced over a four- or five-year model cycle, the Volt will go through various same-model updates during its lifespan.

We can see the used-car ads now:

For Sale. Chevy Volt 1.3.1 SP2.

Weber also said that the priority for engineers working on the Voltec power train is not to get more power or endurance from the current 181kg battery pack – GM reckons 40 miles of battery-only endurance is more than sufficient - but rather get the same performance from a smaller, cheaper unit that can then be used in Volt 1.1 or 1.3. ®

    Are you competent? Ethical? Welcome to UKCSC's new list

    Frustrated at lack of activity from the "standard setting" UK Cyber Security Council, the government wants to pass new laws making it into the statutory regulator of the UK infosec trade.

    Government plans, quietly announced in a consultation document issued last week, include a formal register of infosec practitioners – meaning security specialists could be struck off or barred from working if they don't meet "competence and ethical requirements."

    The proposed setup sounds very similar to the General Medical Council and its register of doctors allowed to practice medicine in the UK.

  • Microsoft's do-it-all IDE Visual Studio 2022 came out late last year. How good is it really?

    Top request from devs? A Linux version

    Review Visual Studio goes back a long way. Microsoft always had its own programming languages and tools, beginning with Microsoft Basic in 1975 and Microsoft C 1.0 in 1983.

    The Visual Studio idea came from two main sources. In the early days, Windows applications were coded and compiled using MS-DOS, and there was a MS-DOS IDE called Programmer's Workbench (PWB, first released 1989). The company also came up Visual Basic (VB, first released 1991), which unlike Microsoft C++ had a Windows IDE. Perhaps inspired by VB, Microsoft delivered Visual C++ 1.0 in 1993, replacing the little-used PWB. Visual Studio itself was introduced in 1997, though it was more of a bundle of different Windows development tools initially. The first Visual Studio to integrate C++ and Visual Basic (in .NET guise) development into the same IDE was Visual Studio .NET in 2002, 20 years ago, and this perhaps is the true ancestor of today's IDE.

    A big change in VS 2022, released November, is that it is the first version where the IDE itself runs as a 64-bit process. The advantage is that it has access to more than 4GB memory in the devenv process, this being the shell of the IDE, though of course it is still possible to compile 32-bit applications. The main benefit is for large solutions comprising hundreds of projects. Although a substantial change, it is transparent to developers and from what we can tell, has been a beneficial change.

  • James Webb Space Telescope has arrived at its new home – an orbit almost a million miles from Earth

    Funnily enough, that's where we want to be right now, too

    The James Webb Space Telescope, the largest and most complex space observatory built by NASA, has reached its final destination: L2, the second Sun-Earth Lagrange point, an orbit located about a million miles away.

    Mission control sent instructions to fire the telescope's thrusters at 1400 EST (1900 UTC) on Monday. The small boost increased its speed by about 3.6 miles per hour to send it to L2, where it will orbit the Sun in line with Earth for the foreseeable future. It takes about 180 days to complete an L2 orbit, Amber Straughn, deputy project scientist for Webb Science Communications at NASA's Goddard Space Flight Center, said during a live briefing.

    "Webb, welcome home!" blurted NASA's Administrator Bill Nelson. "Congratulations to the team for all of their hard work ensuring Webb's safe arrival at L2 today. We're one step closer to uncovering the mysteries of the universe. And I can't wait to see Webb's first new views of the universe this summer."
