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.

Junkyard Gem: 1969 Cadillac Coupe DeVille

The Cadillac Division was riding high in 1969, with sales numbers far surpassing those of Lincoln and Imperial. A few more years remained before fuel prices would go crazy, and prosperous Americans knew that a sleek DeVille or Eldorado gave them bragging rights at the country club. Here's a thoroughly used-up '69 Coupe DeVille, finally at the end of its journey and residing in a self-service wrecking yard in Denver, Colo. This inspection certificate shows that the car lived in Louisiana a decade ago. Since this is the sort of pervasive rust that occurs in places much wetter than arid High Plains Colorado, we can assume that this DeVille spent many years in the land of gumbo and alligators. The decklid sports Fleetwood badging and a Rickenbaugh Cadillac emblem, but Cadillac didn't make two-door Fleetwoods in 1969. Perhaps a Colorado-sold Fleetwood donated its decklid to replace a rust-ravaged lid on this car. Actually, there's a good chance it was purchased at this very yard. The once-opulent interior has suffered greatly over the decades, with the reek of mildewed carpeting and irradiated leather giving it That Hooptie Car Smell. Try to picture what this scene looked like in happier days, a half-century ago. The 1969 Cadillac V8 engine displaced a mighty 472 cubic inches (that's 7.8 liters to those of you living under the cruel knout of the metric system) and delivered a gross 375 horsepower and 525 lb-ft of torque. Scaling in at 4,595 pounds (about a half-ton less than a new Escalade), the DeVille needed that power to keep up with those cheap-but-V8-equipped Chevy Chevelles. For 1970, Cadillac would stroke this engine to a staggering 500 cubic inches for Eldorado buyers. This engine family lasted through 1984, after which it was replaced by the much-loathed High Technology V8. The build quality and snob appeal of the 1969 Cadillacs kept them on the road for decades after most of their peers got crushed, but this one was just too far gone to be worth restoring.

GM recalls 61k more vehicles in three campaigns

Following a stop-delivery order for its new midsize trucks and a rash of recent recalls, General Motors is issuing three more campaigns covering 60,575 vehicles in North America with 57,182 of them in the US. As of October 1, the automaker has issued a total of 74 recalls (see the ridiculously long chart to the right) this year covering 26,495,070 units in the US.
The largest campaign covers 46,873 examples in the US of the 2008-2009 Pontiac G8 and 2011-2013 Chevrolet Caprice Police Patrol Vehicle imported from Australia. It's possible for the driver's knee to hit the key and make it move from the "Run" to "ACC" position while driving. GM says its Holden division is developing a fixed-blade key that's supposed to fix the problem by only allowing it to rotate toward the "On" position. There has been one crash caused by this fault but no injuries or fatalities.
The second recall is for 10,005 units of the 2004-2007 Cadillac CTS-V and 2006-2007 Cadillac STS-V because "the fuel pump module electrical terminal may overheat." This can cause a flange to melt and allow the pump to leak fuel. GM specifies that the remedy for the CTS-V is replacing the fuel module and fuel tank jumper harness, but it doesn't specify how the STS-V is being repaired.
