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.

Mixed sales results, but automaker stocks rise on need for cars in Houston

DETROIT — The Big Three Detroit automakers on Friday reported better-than-expected August sales and issued optimistic outlooks for demand as residents of the Houston area replace flood-damaged cars and trucks after Hurricane Harvey, sending their stocks higher. General Motors, Ford and Fiat Chrysler posted mixed August U.S. sales, with GM up 7.5 percent and Ford and Fiat Chrysler down. Japanese automaker Toyota improved sales by nearly 7 percent, while Honda fell 2.4 percent. Still, analysts focused on the potential for Detroit automakers to cut inventories and stabilize used vehicle prices as residents of Houston, the fourth largest city in the United States, are forced to replace tens of thousands, perhaps hundreds of thousands, of vehicles after the devastation from Hurricane Harvey. Mark LaNeve, Ford's U.S. sales chief, told analysts on Friday that following Hurricane Katrina in 2005 "we saw a very dramatic snapback" in demand. That said, Ford sales fell 2.1 percent in August. It sold 209,897 vehicles in the United States, compared with 214,482 a year earlier. Sales were down 1.9 percent in the Ford division and off 5.8 percent at Lincoln. Demand was down for cars, crossovers and SUVs. It was not clear how many vehicles in the Houston area will be scrapped, LaNeve said, saying he had seen estimates ranging from 200,000 to 400,000 to 1 million. Ford's Houston dealers may have lost fewer than 5,000 vehicles in inventory, he said. Ford is the No. 1 automaker in the Houston market, with 18 percent share, according to IHS Markit. The company plans to ship used vehicles to Houston dealers and has "every indication we would have to add some production" of new vehicles to meet demand, LaNeve said. Investor concerns about inventories of unsold vehicles and falling used car prices have weighed on Detroit automakers' shares most of this year. Now, automakers can anticipate a jolt of demand from a big market that is a stronghold for Detroit brand trucks and SUVs. "It's got to be a positive for the industry," LaNeve said. Investors appeared to agree. GM shares rose as much as 3.3 percent to their highest since early March. Ford increased 2.8 percent at $11.34, and Fiat Chrysler's U.S.-traded shares were up 5.2 percent $15.91, hitting their highest in more than five years. GM reported a 7.5 percent increase in U.S. auto sales in August, helped by robust sales of crossovers across its four brands.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.
