GM shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.

Here are all the EVs with 800V charging available in 2024

As technology advances, electric cars are improving their fast-charging times. That means less time spent waiting at a DC public charger when you’re out on the road. While Level 3 chargers used to provide a maximum of 150 kilowatts of power, 350-kW chargers are become more common, making for super-fast charging Â… if your car is capable of taking advantage of it. So how do automakers improve the charging speed of their EV batteries? Some are turning to higher voltage, specifically 800V charging. What's the difference between 800-volt charging and 400-volt charging? So how does 800V charging improve upon the more common 400V EVs? Put simply, the higher the voltage, the less amperage (current) it requires to charge. In other words, with more voltage, you get more wattage (power, aka charge rate) from the same amperage (current). 800V architecture is also more efficient, with less electrical resistance, so it can use thinner cables and smaller, lighter components while needing less cooling. The tradeoff is that it is more costly, and guess who that cost gets passed on to. While automakers don't break down their pricing to show how much more you're paying for that 800V system, you'll just have to evaluate any potential purchases as a whole, and make your decision based on overall pricing of the vehicle. Thankfully, the 800V EVs on sale now are generally ones we like. Now, 800V charging capability doesn't necessarily mean an EV has 800V vehicle architecture. For instance, the GMC Hummer EV and Chevy Silverado EV operate at 400V, but with their dual battery packs, can switch to 800V when charging by temporarily connecting those packs in series. Currently, there are only a handful of EVs available with 800V charging. But if you are going to find yourself taking longer trips in your EV and using DC fast chargers more often, you might want to consider choosing one with this faster charging capability. With that in mind, these are the EVs available with 800V charging, either on sale now or coming in 2024. 800-volt EVs available in 2024 Audi E-Tron GT Chevrolet Silverado EV Genesis GV60 Genesis Electrified G80 Genesis Electrified GV70 GMC Hummer EV Pickup GMC Hummer EV SUV GMC Sierra EV* Hyundai Ioniq 5 Hyundai Ioniq 6 Kia EV6 Kia EV9 Lotus Eletre* Lotus Emeya* Lucid Air Lucid Gravity* Porsche Macan Electric* Porsche Taycan Ram 1500 REV* Tesla Cybertruck *Coming later in 2024 Green Audi Chevrolet Genesis GMC Hyundai Kia Lotus Porsche Tesla Electric Lucid EV charging

Here are all the cars GM is axing as part of its restructuring

GM plans to kill off a couple of great and a few meh cars as part of its restructuring. Here's a rundown of all the cars being phased out of production. None of the vehicles GM axed were SUVs or crossovers. Instead, it was an action reminiscent of what Ford recently decided to do by discontinuing U.S. sales every Blue Oval sedan. GM just didn't explicitly say, "We're killing our cars," like Ford did — probably a smart move by GM. Keep scrolling down to see the full list of deceased GM models. Chevrolet Volt This one was the most surprising of all the cars GM decided to can, primarily because cars with plugs are supposed to be our future. However, maybe consumer demand just isn't quite there yet for a plug-in like the Volt. We came up with all sorts of ideas for what was to blame for the untimely demise of the Volt, so go check that out for a full breakdown of the situation. Cadillac CT6 Here's another car we'll be sad to see go. Cadillac's flagship sedan was such a joy to drive, and it served as the conduit to deliver GM's semi-autonomous Super Cruise system, which still hasn't been surpassed by any other company's technology in our books, even Tesla's Autopilot. That being said, GM does plan to produce the CT6 until March, with the last cars coming off the line set to be twin-turbo V8 V-Series models. If it's going to go, this seems like a pretty great way to make an exit. We'll be patiently awaiting the next flagship Cadillac once this one finally fades away. Chevrolet Impala The Impala is actually a pretty good car. It doesn't sell terribly, and we think it's a completely satisfactory car to drive. However, people would rather have a Traverse or Equinox these days, making the Impala one of the vehicles to find itself on this list. Chevrolet is keeping its smaller brother, the Malibu, but a big, full-size sedan just isn't what people are ordering up these days. It's unfortunate to see it go, but we won't be broken up over it. Chevrolet Cruze We wouldn't rank the Cruze at the top of the compact car class, but if you were looking for a small, cheap American car, it was either this or the Focus. The Cruze had the potential to be a true small performance car if Chevy had ever wanted to make it into one. But sadly, we're seeing it bow out before Chevy ever tried to slot a hot engine and suspension in there to make it competitive with other hot hatches. A Cruze SS would have made enthusiasts take notice.
