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.

2014 Cadillac CTS debuts new design, twin-turbo power, Vsport model [w/video]

If ever there were a Cadillac to truly rival the world's best, this could be it.
With every new model, Cadillac indeed gets closer and closer to actually performing at the top of its class, rivaling those crafty Germans at their own sport/luxury sedan game. The best example yet of Cadillac's efforts to challenge the world came last year, when we met the 2013 ATS - a vehicle that we praised for its on-road dynamics and interior refinement, and later went on to be named North American Car of the Year.

Cadillac issues stop sale on ATS to recall 82k units

Cadillac is issuing a recall on 82,620 examples of the 2013-2016 ATS worldwide to fix a compliance issue with the sunroof controls. Until a service bulletin goes out to take care of things, there's also a stop sale on the luxury compact in the United States, The Detroit News reports. Of the affected models, 63,665 are in the US, according to a statement sent to Autoblog, and 7,922 of them are in Canada. The problem is actually the same issue as a recall on nearly 59,000 examples of the 2013-2015 ATS in the US in February. In them, the controls for the tilt and slide of the roof aren't recessed enough to meet government standards for the force necessary to operate the buttons. The Feds believe that someone could accidentally activate the auto-close and potentially be at risk. At the time, Cadillac dealers installed a new trim plate to add the needed clearance. In the latest update, the company is adding the 2016 model year, and according to The Detroit News, 70 percent of the cars from the original campaign also need another new trim plate. Unsurprisingly for such a minor defect, there are no known crashes, injuries, fatalities, or customer complaints related to this issue, according to the announcement by General Motors. Cadillac ATS Statement: General Motors is recalling 63,665 Cadillac ATS sedans in the United States from the 2013-2016 model years because the power-operated roof panel systems on these vehicles will auto-close when the non-recessed portion of the "Slide" or "Tilt" switches are pressed and the roof panel is open. Because these switches are not fully recessed, they can be actuated with less force than required to comply with applicable federal standards. GM knows of no crashes, injuries or fatalities related to this issue and has received no customer complaints. The total population of the recall including Canada, Mexico and exports is 82,620.
