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.

GM sweetens military discount for Buick, Chevy and GMC

American servicemen and women interested in a new vehicle from Chevrolet, Buick or GMC now have a bit more incentive to head down to their local dealer, as General Motors has announced plans to improve its military discount program.
The new GM Military Discount Program offers eligible consumers a new Chevy, Buick or GMC at invoice pricing, which in some cases can take very large chunks out of a car's retail price. When factored in with other incentives, most of which are available with the Military Discount, the bargains are thick on the ground for members of the US armed forces.
GM's Retail Sales and Marketing Support general manager, Chuck Thomson, said, "GM has long supported the military and military families, and we hope this simplified and enhanced discount will show our appreciation for their service and help make it easier for them to own one of our great new vehicles." The program is open to all active duty and reserve members in the Army, Navy, Marines, Air Force, National Guard and Coast Guard, as well as veterans that have been out of the service for less than a year. Military retirees and their spouses are also eligible for the discount.

Overland Expo's GMC Sierra AT4X is an Aussie-style ultimate overlander

Overland Expo is a caravan of companies producing everything one could need or want for overlanding. So what better what to showcase the kind of hardcore overlander possible by dipping into that parts caravan than to build just such an overlander? That's what the Expo did in creating its second Ultimate Build, based on a 2022 GMC Sierra AT4X. Overland Expo said it chose the Sierra for the 6.2-liter V8 with 420 horsepower and 460 pound-feet of torque because it wanted to "go bigger and more extreme" than its first build last year, which was based on a Toyota 4Runner TRD Off-Road. This Sierra trim was chosen over its AT4 sibling due to the extra dose of rugged, like the Multimatic spool dampers that provide about an inch more suspension travel front and rear, and the front and rear locking differentials. The Denali-like luxury isn't a bad thing to have, either. The only performance mods are a MagnaFlow cat-back exhaust, Firestone Ride-Rite air springs at the bag and 17-inch Icon Dynamics wheels on 33-inch 33 Firestone Destination Mud Terrains replacing the stock 18-inchers on Goodyear Wranglers.   Rig builder Mule Expedition Outfitters tapped more than 21 exhibitors for components, and spent "hundreds of hours" putting them all together seamlessly. The most eye-catching swap comes from the MITS Alloy three-foot canopy and tray that replaces the pickup bed. MITS is an Australian company, hailing from the land that also gives us overlanding powerhouses like ARB and Old Man Emu, and this is a popular outback-style rig. In addition to the storage areas on the sides and underneath, the canopy holds a Dometic refrigerator, Green Goat Outdoors camp kitchen and an eight-gallon water can that feeds a Geyser Systems shower. A solar panel on the roof routes power to a pair of lithium-ion batteries in the canopy as well, their output controlled by a Redarc RedVision Manager30.  There are plenty of Rigid lights for avoiding trouble, and a Forrest Tool Max Tool Kit plus GoTreads for when trouble inevitably appears anyway. The crew cab should hold plenty of gear, but anything else that needs to be stored outside will go in a set of 3D dry bags.
