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 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.

UAW rejects GM contract proposal but makes a counter offer

The United Auto Workers union said a new comprehensive offer made by General Motors Co late Monday to end a two-week-old strike was not acceptable and said it had made a new counterproposal. UAW vice president Terry Dittes said in a letter to members "there are many important issues that remain unresolved." The union is awaiting GM's next proposal. He said GM's offer came up short on many issues.  Dittes said GM made a "comprehensive proposal" at 9:40 p.m. Monday. "This proposal that the company provided to us on day 15 of the strike did not satisfy your contract demands or needs. There were many areas that came up short like health care, wages, temporary employees, skilled trades and job security to name a few." Dittes is the union's vice president for GM relations and the UAW's lead negotiator in these contract talks. "We have responded today with a counterproposal and are awaiting GM's next proposal to the union," he wrote. "Regardless of what is publicized in print or social media, etc., there are still many important issues that remain unresolved." The strike, in its third week, has cost GM more than $1 billion, according to J.P. Morgan analyst Ryan Brickman. He said the cost per day in potential profit is $82 million. However, another analysis, by East Lansing-based consultant Anderson Economic Group, put the losses at $25 million a day. And the effects of the strike are expanding. GM said Tuesday the strike has created a parts shortage that forced the automaker to halt production at its pickup and transmission plants in Silao, Mexico, temporarily laying off 6,000 workers. Silao is where GM builds its highly profitable four-door crew cab Chevy Silverado and GMC Sierra pickups. The strike has also forced GM to idle some Canadian workers, and many suppliers have been forced to halt operations. About 48,000 UAW members went on strike on Sept. 16 seeking higher pay, greater job security, a bigger share of the leading U.S. automaker’s profit and protection of their healthcare.
