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.

Refreshed GMC Terrain is introduced. Again.

Back in January of last year, we got our first look at the refreshed GMC Terrain that was supposed to go on sale sometime last fall as a 2021 model. But that was January 2020, just a couple of blissful months before the world shut down. So the Terrain ended up delayed, just like the Chevy Equinox, and now GMC is re-introducing us to the refreshed crossover, which is slated as the 2022 GMC Terrain. This time around, we've been shown photos of not just the new AT4 off-road oriented trim, but other more common variants. They all get larger grilles, larger headlights and new C-shaped taillights, and all trims get fulling LED exterior lighting. Both the AT4 and Denail get unique grille designs, with the former getting a gunmetal grey design with thick slats, and the latter getting an all-chrome one with more delicate lattice-work between the slats. The AT4 also boasts a front skid plate for protection, and from our early preview last year, it seems to get chunkier tires. The Elevation trim returns, too, as a black-out appearance package for the more entry-level SLE and SLT trims. The interior is mostly unchanged except for a revised shifter panel -- the buttons are new, but the same controversial design remains (see the video below). There are new features available, though. Apple CarPlay and Android Auto are still standard, but now they're wireless. A head-up display is available as an option for SLT and AT4, while it comes standard on the Denali. The Denali also gets an 8-inch screen in the instrument panel. Only the turbocharged 1.5-liter four-cylinder and nine-speed automatic have been announced for the Terrain. It makes the same 170 horsepower and 203 pound-feet of torque as before and can be paired with either front- or all-wheel drive. We're expecting a higher-horsepower, larger-displacement engine to be offered in the near future. The SLE, SLT and AT4 models will go on sale this summer. The Denali will follow in the fall. Pricing and additional details should be revealed in the coming months. Related Video:

Plus, it gains the AT4X trim for more off-road prowess and keeps all that was good from before. Score: 8.0 What it competes with: Ford F-150, Ram 1500, Toyota Tundra, Nissan Titan, Chevrolet Silverado 1500 Pros: Top-notch luxury interior, stout capability, wide range of great powertrains Cons: Ride is flinty/rough, looks that divide From the editors: Road Test Editor Zac Palmer — "It really depends on what trim level you spring for with the Sierra. Buy the Denali Ultimate, and the interior is just as good as the competition. If you're not going all out on luxury features, though, at least get the diesel. It's the smoothest operating diesel engine out there, and it's also efficient. This is one great truck when you set it up in the ideal configurations." Senior Editor James Riswick — "The GMC Sierra Denali interior has gone from "They just didn't try" to "They tried harder than everyone else." The Denali Ultimate's design, detailing and materials are particularly impressive. If you want a luxury truck, this delivers."
