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 Yukon AT4 to offer 6.2-liter V8

A year ago, GM said it was considering making its 6.2-liter V8 available outside the flagship trims of its full-sized SUV trio of Chevrolet Tahoe and Suburban, and GMC Yukon. There has been a year of gnashing teeth on GM forums since the automaker decided to meditate on the issue, but GM Authority reports The General has finally made the call — the 2022 Yukon AT4 will offer the 6.2-liter. This follows last week's news that three 2022 Chevrolet Tahoe and Suburban trims would also add the 6.2-liter as an option. With the Yukon Denali already in the 6.2-liter camp, only the Yukon SLE and SLT will be left out. Those latter two levels will continue to offer the 3.0-liter Duramax diesel as the optional engine, which the AT4 trim cannot take advantage of because the AT4's front fascia and skid plate interfere with the diesel's plumbing. The 5.3-liter V8 that's the standard engine makes 355 horsepower and 383 pound-feet of torque. The 6.2-liter makes 420 hp and 460 lb-ft. As has been pointed out, the 5.3-liter can tow 200 pounds more than the 6.2, but fuel economy is a wash — the 5.3 only gains 1 mpg in the city over the 6.2. This is a pure power play. For the moment, it looks like Yukon AT4 buyers won't need to do anything other than check a box to get the 6.2-liter. That's the opposite of what some Tahoe and Suburban buyers will face when trying to get the 6.2-liter for their rigs; outside of the Premier trim, Chevy put the engine behind a paywall of option packages. Since GMC hasn't revealed pricing for the 2022 lineup yet, we don't know what the surcharge will be for the big engine. The GMC Sierra AT4 pickup charges $2,195 to go from the 5.3 to the 6.2, so that's probably in the ballpark. Related Video: This content is hosted by a third party.

eBay Find of the Day: 1976 GMC Motorhome is a jolly green giant

If you have a need to relive the 1970s, then here is the vehicle for you. This groovy blast from the past is a 1976 GMC Motorhome currently for auction in Florida on eBay Motors, and it is one green machine - just not in the modern sense.
The seller claims that this beast has had just two owners and has covered a mere 61,308 miles in its decades on the road. It's reportedly never been restored or repainted and comes with all of the necessary books and manuals. A 7.5-liter (455-cubic-inch) Oldsmobile V8 with a three-speed Turbo-Hydramatic automatic transmission powering the front wheels propels this far-out RV, and the double set of rear wheels out back use a self-leveling air suspension to provide a cushy ride.
The purported low miles and good condition really make this GMC a stand out, though. The exterior combination of lime stripes and beige with just a touch of green is like nothing else on the road today. Plus, the polished bumpers and wheels make it all pop. Inside, it's even better with monochromatic green upholstery and shag carpet. It features everything you'd ever need on a long trip, including a bathroom, kitchenette and lots of seating. The only hint of modernization is an HD TV next to the stove, but its size is a perfect fit for the hole there.
