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.

2022 GMC Sierra Denali Ultimate vs. 2022 Ram 1500 Limited Longhorn vs. Ford F-150 Limited | Luxury truck interior face-off

GMC's new uber-expensive 2022 Sierra Denali Ultimate is the latest luxury truck to nudge toward six-figure territory. With demand for upmarket half-tons surging, GMC's otherwise-solid pickup found itself in desperate need of an interior remodel. For 2022, we're getting just that, and it appears ready to take the fight to the segment's best, including the 2022 Ram 1500 Limited and 2022 Ford F-150 Limited. Here's the new Denali Ultimate interior in all of its full-grain, open-pore glory. 2022 GMC Sierra 1500 Denali Ultimate vs. 2021 GMC Denali  Not only did the material quality and styling both improve greatly, but the new truck also gets a completely different shifter setup (truck buyers don't like column shifters anymore, apparently). It would actually be difficult to overstate the quality of the upgrade here; the photos really speak for themselves. It's also worth noting that in addition to looking significantly more upscale than the model it's succeeding, the new Denali interior also differs a bit more from its Chevy counterpart than its predecessor did. Here's the new Silverado High Country for reference: While some elements do carry over, the entire dash design is different, down to the positioning of the heating and cooling vents. While the main HVAC controls are essentially carried over, note that they're pretty much the only ones. Even the horizontal bar of switches running along the center stack is positioned differently between the two. Yep. This is a pretty big upgrade over the 2021 cabin, and clearly the range-topper in GM's truck hierarchy. But what of the competition? 2022 GMC Sierra 1500 Denali Ultimate vs. 2022 Ram Limited Longhorn Southfork This one's tough. We're going to have to spend time in them back to back, but the Ram Limited, with its various anniversary editions and other special permutations, is certainly the interior to beat. To our eyes, the Sierra's more horizontal layout is a bit more modern and perhaps luxurious-looking than the more upright cabin treatment of the Ram, but it's tough to say for certain from photos. Both the Denali Ultimate and Ram Limited carry their upscale feel into their back benches too, which is something we can't say quite as confidently about our next contestant.  2022 GMC Sierra 1500 Denali Ultimate vs. 2021 Ford F-150 Limited The Ford F-150 Limited holds its own, but it's probably the least photogenic of the models we've looked at here, at least apart from the outgoing Denali.

Consumer Reports declares most and least loved cars [w/video]

Consumer Reports is crunching the numbers from its annual owner-satisfaction survey, and part of that process is finding out how attached drivers are to their cars. CR simply asks readers of models up to three years old if they would buy the same vehicle again in light of their entire ownership experience, and tallies the results. After looking at the responses for about 350,000 vehicles, it turns out that people really love a certain California-built, electrically powered luxury sedan. That's right, this year's the overall winner was the Tesla Model S with a whopping 98 percent of owners saying they would purchase another one (the Model S also won this award last year, with 99 percent satisfaction). The Chevrolet Corvette Stingray came in a close second with 95 percent of drivers hoping to park another one in their garage. A few models weren't quite so favored, though. The Nissan Versa Sedan was the least loved model among its owners; a mere 42 percent said that they would purchase another. The aging Jeep Compass didn't do much better, with just 43 percent of drivers willing to buy the softroader again. On average, about 70 percent of owners say they would buy their car again, and only four cars ranked below 50 percent in CR's findings. Check out the video above to see some of the winners and losers in a few of CR's categories. If you're a subscriber, you can check out the full list on its website.
