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.

Canada opens probe into 250,000 GM pickups, SUVs over brake performance

Transport Canada, the auto safety regulator, has opened a probe into braking issues in nearly 250,000 General Motors full-size pickups and SUVs after U.S. officials launched a similar probe last year, the agency said on its website. The U.S. National Highway Traffic Safety Administration (NHTSA) in November into 2.73 million U.S. 2014-2016 model year SUVs and pickups after receiving 487 reports of hard brake pedal effort accompanied by extended stopping distance that were attributed to deterioration of the engine-driven brake assist vacuum pump. Transport Canada's probe covers 249,700 2015 through 2017 model year vehicles including the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon as well as 2014-2017 Chevrolet Silverado LD and GMC Sierra LD vehicles. The U.S. agency said it had reports of nine incidents of vehicles incurring damage as a result of colliding with another vehicle or fixed object at low speeds and reports of two injuries. NHTSA said if the pump fails to operate, the amount of brake power assist can be significantly reduced, extending vehicle stopping distance. The NHTSA sent GM an information request in a Feb. 7 letter. A GM spokesman said he had no update on the investigation. Reporting by David Shepardson; editing by Jonathan Oatis

Chevy, Lincoln dealers say they still want sedans

Detroit automakers have famously turned their backs on sedans as they make the strategic bet to double down on money-making trucks and SUVs, but dealers for at least two American brands are giving the companies contrary signals. In separate recent interviews with leading national dealer councils for Chevrolet and Lincoln, Automotive News reports that both brands’ dealers still see a need for cars. The publication published a Q&A interview with Mike Bowsher, chairman of the Chevrolet National Dealer Council, who said Chevy dealers managed to hold onto market share last year despite the phase-out of the Cruze compact sedan and hatchback, thanks to products like the Spark and Sonic subcompacts and the Trax and Equinox crossovers. But, he acknowledged, “We do feel like we could use a car, especially in the low-MSRP range.” The comments follow similar recent comments from Tom Lynch, who chairs the Lincoln National Dealer Council. He told AN, “If weÂ’re not in segments where there is still a good amount of business, I think the company and the dealers lose out.” The Cruze was one of the victims of GMÂ’s November 2018 announcement of plant closures, with production having ceased with the closure of GMÂ’s Lordstown, Ohio assembly plant last year. GM sold 47,975 Cruzes in 2019 but a healthy 142,617 in 2018. At Lincoln, Lynch said the council has been telling the company it needs to stick with the sedan segment, despite plans to kill the MKZ sedan in the coming months and unconfirmed reports that the Continental isnÂ’t long for this world, either, despite the buzz of the suicide-door Coach Door Edition, shown in the photo above. Lincoln sold 17,725 MKZs and 6,586 Continental sedans in 2019, down a combined 15%, but still good for almost 22% of overall Lincoln sales. It's worth noting that Lincoln competes in a luxury segment that still expresses allegiance to four- and two-door cars. Even Cadillac, its cross-town rival, is staying active with the upcoming CT5 and CT4 sedans. Lynch pointed to Tesla as evidence that strong sedan products can resonate with consumers, though he conceded that “What that looks like for Lincoln going forward, IÂ’m not sure of.” For now, anyway, Chevy still offers the Sonic and Spark subcompacts, the latter of which saw sales climb 32.5% in 2019 to 31,281 (Sonic sales fell nearly as steeply).
