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.

Junkyard Gem: 1990 GMC S-15 Jimmy 4x4

The General sold the GMC-badged version of the first-generation Chevy S-10 Blazer, known as the S-15 Jimmy or just the Jimmy, from the 1982 through 1994 model years. These trucks were based on the small S-10 pickup and sold well (until small trucks were forced to get bigger and less truck-like after the dawn of the Ford Explorer-inspired commuter-truck era), but they have become difficult to find in vehicle graveyards in our current century. Here's a '90 Jimmy 4x4 with red-primer paint job, found in a self-service yard on California's Central Coast last month. GMC shoppers could get the 1990 Jimmy as a rear-wheel-drive truck, but this one has the four-wheel-drive option that allowed Tahoe-bound skiers to skip the chain monkeys on the way to the slopes (the CHP, understanding that California drivers have a 95% mortality rate on snow or ice, requires chains or four-wheel-drive to get over Donner Pass when there's a hint of snow forecast). GM sold so many millions of small-block Chevrolet V8s that it made economic sense to use the same tooling to produce a V6 version. The result was this truck's 4.3-liter V6 that was three-quarters of the good old Chevy 350 (5.7-liter) V8 that powered so many Camaros, Chevelles and Impalas. The 4.3 didn't make smooth power, but it got the job done and held together quite well. This one was rated at 160 horsepower, good enough for the Jimmy 4x4's 3,512-pound curb weight. These days, though, used-truck shoppers insist on at least two tons of heft plus four doors. Some discount lot in Monterey or Salinas couldn't even get $999 for this truck, and so it ended up in the final stop before the cold steel jaws of the crusher. 1990 was the last model year for the two-door-only Jimmy; for 1991, the Jimmy came with a choice of two doors (for devil-may-care types) or four doors (for drop-the-kids-at-school types). I've always liked the look of the instrument panels on the early S-10s and its siblings; even though the designers had to work within strict budgetary limitations, they made the panels look interesting. This truck nearly made it to 170,000 miles before the end. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. So powerful with the 4.3 (the regular S-15 pickup still came with a 2.8-liter V6 as base equipment) that it could destroy a TV camera.

GMC Hummer EV SUV prototypes hit the trails in Moab

It seems like GMC's new Hummer EV pickup only just hit the market, but it's almost time to roll the hype train back through for the next installment: the SUV. GM President Mark Reuss shared images of some prototypes crawling on the rocks outside Moab in what he called "final testing validation" ahead of the SUV's projected arrival in showrooms some time in early 2023.  "With its aggressive 49-degree departure angle and tight turning radius of just 35.4-feet, the HUMMER EV SUV’s maneuverability, capability and performance make it an off-road supertruck," Reuss said in the post accompanying the photos. The over-the-river-and-through-the-woods routine depicted in the photos doesn't reveal much we don't already know about the forthcoming electric 4x4, but we can at least contextualize that 49-degree departure angle; the best you'll get from any Jeep Wrangler currently on sale is 40.4 degrees.  GMC's Hummer SUV will launch early next year with an 830-horsepower drivetrain, offering roughly 300 miles of driving range. Pricing will start at $105,595 before options. Later in 2023, GMC will release an EV2X variant with up to 625 horsepower, similar range and an $89,995 price tag.
