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 issues stop-sale for 3 SUVs over incorrect MPG rating

This week, GM sent a memo to Chevy, GMC, and Buick dealers to tell them to stop selling three SUVS. The 2016 Chevy Traverse, the GMC Acadia, and the Buick Enclave all have EPA window stickers that show higher fuel economy ratings than the vehicles actually have. Unlike other recent – and very public – fuel economy ratings problems from VW and Mitsubishi, it doesn't seem like GM did anything wrong with the testing for these vehicles, it just misprinted the labels. New labels are being printed and should arrive at dealerships this weekend and early next week. After that, the SUVs will be able to be sold and delivered again. The official fuel economy rating for the three SUVs are all the same. The correct numbers for the all-wheel drive versions are 17 miles per gallon combined, 15 city, and 22 highway. The stickers say the SUVs get 17/24/19. The front-wheel driver models were also incorrectly labeled, and the total number of affected vehicles is 59,823. In the memo, GM said the problem was caused by an "inadvertent error," Automotive News says. GM is working with the EPA to solve the issue. We have asked GM for a comment on the mistake and will update this post if we hear back. Related Gallery 2013 GMC Acadia View 16 Photos News Source: Automotive News – sub. req.

GMC Terrain Nightfall Edition is murdered-out for the masses

We've lost track of how many special edition Chevrolet Silverado and GMC Sierra pickups there have been over the past few years. But while some special editions can be kitschy, there's nothing overtly bad about the GMC's Nightfall line. We've already seen the blacked-out look on Canyon Nightfall and Sierra All Terrain X pickups, and now, it's being applied to the Terrain. As with the trucks, the Terrain Nightfall's changes are simple: the chrome-heavy finish is replaced with gloss-black accents where applicable. That's what you'll find on the grille surround, the front and rear fascia accents, the license-plate surround, mirror caps, and roof rack. Like Jay Z said, all black everything. Except for the wheels, of course – those have machined faces with black spokes. The grille inserts aren't strictly black either (they're charcoal), and as counterintuitive as it may seem, owners can choose from three body paints in addition to Onyx Black (Summit White, Graphite Gray, and Crimson Red). The Terrain Nightfall Edition will be offered on the SLE-2 and SLT trims, with prices to be announced closer to its fall 2016 on-sale date. GMC Introduces 2017 Terrain Nightfall Edition The News Ahead of its debut at the New York International Auto Show, GMC today introduced the 2017 GMC Terrain Nightfall Edition – a stylized special edition combining blacked-out exterior details and wheels, with popular technologies such as IntelliLink with available 4G LTE connectivity and Wi-Fi hotspot. It joins the Canyon Nightfall Edition and the all-new Sierra All Terrain X as the latest GMC vehicle to offer an exclusive, personalized appearance with the Terrain's premium features and refinement. Product Details The Terrain Nightfall offers an edgy appearance with 18-inch machine-faced aluminum wheels and gloss black spokes, a charcoal grill with a gloss black surround and accents, gloss black front and rear fascia accents, gloss black rear license plate surround trim, gloss black outside mirrors and black luggage rails. Terrain Nightfall Edition will be offered on SLE-2 and SLT models with four exterior color options: Summit White, Onyx Black, Graphite Gray Metallic and Crimson Red Metallic. On Sale Fall 2016 Quotable "Building on its best year ever, Terrain continues to attract new and style-conscious customers to GMC," said Duncan Aldred, vice president of GMC Sales and Marketing.
