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.

Huge, pricey trucks haul jobs and profits for the Detroit Three

DECATUR, Texas — Mickey McMaster is on his 12th pickup truck. The 61-year old farm equipment dealer in Decatur, Texas, two weeks ago treated himself to a 2019 GMC Denali for around $69,000 — a reward for long hours at work. "For me this is the Cadillac of trucks, it's a real luxury vehicle," McMaster said. "I've worked my way up to afford a truck like this and it shows that I've earned it." McMaster is the kind of customer General Motors Co is banking on as it plans to add 1,000 jobs at a plant in Flint, Michigan that will build a new generation of its largest pickups. Demand from Texas and other heartland states for big pick-ups is providing a lifeline to many workers the No. 1 U.S. automaker is laying off at plants elsewhere. The Detroit Three automakers and thousands of their U.S. workers are counting on customers like McMaster to keep buying bigger and more luxurious pickup trucks even if overall U.S. vehicle demand weakens this year, as most analysts predict. At Flint, GM will build a new generation of its heavy-duty Chevrolet Silverado and GMC Sierras, including luxury models that are some of the most profitable vehicles on the planet. GM, Ford Motor Co and Fiat Chrysler Automobiles NV's Ram division own the segment and are each doubling down with new or redesigned models launching this year. Sales of heavy-duty pickups in the United States have grown to more than 600,000 vehicles a year, up more than 20 percent since 2013, according to industry data. Prices for luxury models can easily top $70,000. GM on Tuesday celebrated the launch of a new generation of heavy-duty GMC and Chevrolet pickups at the assembly plant in Flint, Michigan, that is now building all such trucks for the company. At the same time that GM is laying off thousands of U.S. workers and planning to shutter five North American factories, Flint is hiring. The plant runs on three daily shifts, six days a week. As the new model's assembly system ramps up, the plant's capacity will increase by more than 25 percent, plant manager Mike Perez told Reuters. The Flint plant plans to add 1,000 workers, more than half of the 1,500 factory workers who have asked to transfer from plants GM has targeted for shutdown as part of CEO Mary Barra's restructuring plan. "We're bringing in 50 to 100 people every week," said Perez. Workers last week were still finishing the job of retooling the Flint factory to build the new heavy-duty trucks as part of a $1.5 billion investment project.

2019 GMC Sierra carbon fiber bed: How it's made

FORT WAYNE, Ind. — The redesigned 2019 GMC Sierra has some pretty nifty features, and the one that has had the most attention is the MultiPro flipping and folding tailgate. But the Sierra also features the first-of-its-kind carbon fiber truck bed. It's interesting, of course, for its capabilities, such as being 62 pounds lighter than the all-steel box. It even adds more cargo volume since the material can be assembled and shaped differently from steel. As it turns out, the assembly process is cool, too, which we learned when GMC invited us to see the beds being made. Every GMC carbon fiber bed starts out as perfectly flat sheets of thermoplastic carbon fiber. The sheets consist of a mix of fibers and resins, a bit like the molded carbon fiber parts Lamborghini uses. The sheets are manufactured by Japanese company Teijin, which collaborated with GMC to develop the bed. They're all delivered to Continental Structural Plastics (CSP) in Fort Wayne, Ind., for construction into the actual bed. The company, a subsidiary of Teijin, makes a wide variety of composite and plastic parts for the car industry, including body panels for the C7 Chevy Corvette. The rectangular sheets are cut to shape and stacked up at a giant stamping press. Robots pick up sheets and slide them onto a conveyor that goes into a large oven. The heat softens the parts so they can be stamped. The large primary bed parts such as the base are stamped by CSP's enormous 3,600-ton press, and the smaller ones go through a 1,000-ton press. Each press can do different parts using different stamping dies, and CSP switches between dies to produce different batches of parts. After stamping, the parts roll out mostly ready for assembly, but there are rough edges that are trimmed off by water-jet cutters. These cutting machines also create holes for fasteners and for parts such as tie-down hooks and lights. The stamping process also provides the carbon fiber bed with a unique Easter egg. On the bottom of the base of the bed, there are two words: "Connors Way." This is a tribute to Tim Connors, who was the chief engineer of manufacturing at GM and a strong proponent of the carbon fiber bed. He was tragically killed in a motorcycle crash a few years ago. The words were added to honor him, and they were fortunately approved for production. There are some components to the bed that aren't stamped from the flat sheets of material.
