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.

Texas sues GM, saying it tricked customers into sharing driving data sold to insurers

Texas filed a lawsuit Tuesday against GM over years of alleged abuse of customers' data and trust. New car owners were presented with a "confusing and highly misleading" process that was implied to be for their safety, but "was no more than a deceptively designed sales flow" that surrendered their data for GM to sell. The suit contends that at no point was selling driving data ever even suggested as a possibility, putting GM in violation of the state's consumer protection laws. Texas Attorney General Ken Paxton is seeking a jury trial and at least $10,000 per offense (every GM car sold in the state since 2015) and a hefty add-on of $250,000 in cases where the victim was over 65. Texas seems to be flying high after a recent $1.4 billion settlement from Meta over other privacy concerns. This may well be a way to solve any pending budgetary issues in the Lone Star State.

2019 GMC Sierra Denali Drivers' Notes Review | Half measures

Associate Editor Reese Counts: This truck feels a full generation behind the competition. It's a half measure that feels more like a mid-cycle refresh than a whole new truck. There are a few high points: the 6.2-liter V8 is great (if thirsty) and the bed is wider than anything else in the class. The tailgate, too, is nifty, though some might write it off as a novelty. I also dig the tech, particularly the infotainment system and heads-up display. Ram might brag about its giant touchscreen, but I think I actually prefer the GMC's user interface. The rest can be summed up with a series of shoulder shrugs. The Sierra finally looks different than a Silverado, but I wouldn't call it handsome. The interior is spacious, but I'd knock the design and materials in a $45,000 truck, much less one approaching $70,000. It's not Toyota Tundra levels of terrible, it's just plain, cheap, and not nearly as space efficient as the Ram. It feels like GM's not even trying to move the needle with this truck. The more time I spend behind the wheel, the less I like it. Assistant Editor Zac Palmer: I got to spend a lot of seat time in this 2019 GMC Sierra Denali, and I came away generally unenthused by GM's most luxurious truck. We harp a lot about how expensive pickup trucks are these days, and this one's near $70,000 price tag is just the same. When you step inside a similarly-specced Ram, it feels like it's worth its price. When I step out of a Silverado and into a more expensive Sierra, I want to feel like it's money well spent. This Sierra Denali does not. Beyond the leather seats and a few small pieces of wood trim, it's hard, black plastic galore. What makes it all the more frustrating is that GM has most of the tech and features it needs (solid infotainment, 360-degree camera, wireless phone charging and the rear camera mirror is genuinely awesome). The presentation just comes off as dated from the start. It's a shame, because I have a strange affinity for how this truck looks from the curb. The sharp angles, brash styling and "tough truck" attitude is appealing to me. I like stomping on the gas and letting the 6.2-liter torque monster under the hood loose. But man do you pay the price for using that engine. Over a few hundred miles of driving I ended at a dismal 15 mpg reading on the trip computer — the saddest part of this was knowing these were mostly highway miles.
