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 recalling 15k midsize pickups over leaky brakes

General Motors has announced a recall in coordination with the National Highway Traffic Safety Administration related to the brakes on the 2015 Chevy Colorado and GMC Canyon. In the 14,838 units in the United States estimated to be affected, the front brake calipers may be leaking fluid. Needless to say, that could make them less effective, which could hinder the vehicle's ability to stop in time to avoid a collision. The affected units were all manufactured between January 6 and December 24, 2014. The fix seems simple and straightforward enough, with dealers being instructed to inspect the front brake calipers, and replace them if necessary. See below for all the details from NHTSA. RECALL Subject : Brake Fluid Leak Report Receipt Date: MAY 12, 2015 NHTSA Campaign Number: 15V278000 Component(s): SERVICE BRAKES, HYDRAULIC Potential Number of Units Affected: 14,838 Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Colorado, and GMC Canyon trucks manufactured January 6, 2014, to December 24, 2014. The affected vehicles may experience the front brake calipers leaking brake fluid. This is due to air pockets, an imperfection in the metal caliper body. CONSEQUENCE: If the vehicle experiences a brake fluid leak it can increase the stopping distance, increasing the risk of a vehicle crash. REMEDY: GM will notify owners, and dealers will inspect and replace the front-brake calipers if necessary, free of charge. The recall is expected to begin July 10, 2015. Owners may contact GM customer service at 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14888. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Auto sales in March and first quarter down nearly across the board

Nearly every major automaker reported weak U.S. sales for March and the first quarter of 2019, citing a rough start to the year, but said a robust economy and strong labor market should encourage consumers to buy more vehicles as 2019 rolls on. GM, which no longer releases monthly sales figures, saw first-quarter sales fall 7 percent, with declines across all brands. Sales of Silverado pickup trucks fell nearly 16 percent and the high-margin Chevy Suburban large SUV dropped 25 percent. Ford also no longer releases monthly sales numbers, but is due to release its first-quarter sales figures on Thursday. According to industry data, Ford's sales fell 2 percent in the quarter and 5 percent in March. Ford representatives did not immediately respond to requests for comment. FCA reported a 7 percent fall in U.S. sales in March and a 3 percent drop for the first quarter. All of FCA's brands dropped in March, except for Ram, which saw a 15 percent increase in pickup truck sales. "The industry had a tough first quarter, but with spring finally starting to show its face and continued strong economic indicators ... we are confident that new vehicle sales demand will strengthen going forward," FCA's U.S. head of sales, Reid Bigland, said in a statement. Toyota reported a 3.5 percent fall in U.S. sales in March and 5 percent for the first quarter, hurt by declining demand for its Corolla sedans and Camry vehicles. "While some of our competitors are abandoning sedans, we remain optimistic about the future of the segment," Toyota said in a statement. Nissan posted a 5.3 percent drop in sales in March, and its first-quarter sales were down 11.6 percent. Honda and Hyundai bucked the trend. Honda's U.S. sales rose 4.3 percent in March and 2 percent in the quarter, while Hyundai's were up 1.7 percent and 2.1 percent, respectively. Passenger-car sales suffered throughout the January-March quarter compared with the same period in 2018 as Americans continued to abandon them in favor of larger, more comfortable pickup trucks and SUVs, which are far more profitable for automakers. The battle for market share in the particularly lucrative large-pickup truck market intensified in the quarter, as Fiat Chrysler Automobiles' Ram brand outsold the U.S.' No. 1 automaker General Motors' Chevrolet-brand trucks. The two automakers have both launched redesigned pickup trucks.
