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.

GMC Hummer EV could have had the Chevrolet Avalanche's Midgate

One of the many rumors swirling around the GMC Hummer EV claimed the truck would resurrect the Midgate inaugurated by the original Chevrolet Avalanche. Although we now know there's no way to fully knock down the partition between the cab and the cargo box, the firm revealed the rumor wasn't entirely false. "There was [a Midgate] early on. We opted for the functionality of the drop glass in the back. With the package layout and things like that, it was not advantageous to pursue that one. And, the five-foot bed was kind of the industry standard in regards to price of entry in that segment," explained John Mack, the Hummer's exterior design management, during an interview with Muscle Car & Trucks. The Hummer will go on sale with a five-foot box, and it doesn't sound like a longer bed will be available, so a modern version of the Midgate would have made the model more versatile by giving users the ability to fold down the partition behind the rear seats to carry bulky items, like plywood and ATVs. It's a feature that would have inevitably made the truck more complicated to build, however, because it adds moving parts that need to be sealed. Hinges, seals, and latches in turn add weight, and complexity almost always invites high manufacturing costs. As an electric pickup built with newly-developed components, the Hummer already has enough of each. Motorists who need to carry something that's significantly longer than the cargo box aren't entirely out of luck. As Mack pointed out, the rear window drops into the partition, so owners will have the ability to haul surfboards, lumber, or anything else that's relatively long and reasonably thin by simply pushing a switch. Alternatively, the only thing limiting cargo space when the roof comes off is the sky — or, depending on where you live, bridges. Mack didn't reveal when the Midgate was dropped. GMC launched the Hummer project in April 2019, and it previously released early design sketches that show how the truck transitioned from a sketch to a prototype. As of writing, nothing suggests the Midgate will make a comeback in the near future on any member of the General Motors portfolio. It was introduced in 2001 on the first-generation Chevrolet Avalanche, which went on sale in the United States for the 2002 model year. It later spread to Cadillac's luxed-up variant of the truck, the Escalade EXT, and to the short-lived GMC Envoy XUV.

2021 GMC Canyon AT4 will offer an Off-Road Performance Edition Package

In March 2018, GMC announced the 2019 Sierra 1500 AT4, the alphanumeric finale denoting heightened ridge height and off-road capability. In December of that year, GMC took the AT4 further, creating an Off-Road Performance Package that boosted horsepower and torque, and re-soled the 18-inch machined rims in Goodyear Wrangler DuraTrac Mud Terrains. History will repeat itself in 2020, one truck size category down. GMC unveiled the Canyon AT4 (pictured) in Vail, Colorado, earlier this month, and now GM Authority reports that a Canyon AT4 Off-Road Performance Edition Package is on the way later this year.  The Canyon AT4, which replaces the Canyon All Terrain, upgrades the standard truck with all the erstwhile All Terrain kit like tuned suspension, Advanced Hill Descent Control, transfer case skid plate, automatic locking rear differential, and 31-inch Goodyear Wrangler DuraTrac tires on 17-inch aluminum wheels. Design tweaks include the new, bolder front fascia and red recovery hooks. The Canyon AT4 Off-Road Performance Package goes a different route than on the Sierra, improving ruggedness instead of engine output. GMA says the suite includes front and middle performance skid plates, rocker protection, a spray-on bedliner, performance exhaust tip, and 17-inch gloss black aluminum wheels in favor of the Dark Argent Metallic units. A front leveling kit removes the factory rake. This variant will wear a black AT4 badge as opposed to the regular red and chrome AT4 denominator. Inside, we'll guess the AT4's Kalahari stitching and embroidered headrests stay in the game. They'll be joined by all-weather mats. Since GMC hasn't announced the upfit, we don't have pictures or pricing. Tallying up what individual options we could on the 2020 Canyon All Terrain came to $1,970, but that doesn't reflect pricing for next year's new AT4 trim, nor does it include components like the front leveling kit or gloss black wheels. GM Authority said production should begin in June or July, so we can look forward to info closer to summer. Related Video:
