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.

2019 Cadillac Escalade ESV Drivers' Notes Review | Old, but not antiquated

When the Cadillac Escalade debuted 20 years ago, car-based crossovers were just getting their start. The Escalade was and still is basically a Chevy Tahoe with new styling and a nicer interior. That's especially true today, as our test car has an interior that looks like it was lifted straight from a Cadillac CTS rather than a Chevy Silverado. Crossovers may be more comfortable and fuel efficient, but they can't hold a candle to towing and payload capabilities of a body-on-frame SUV. If you need to haul seven people and a full-size Airstream in quiet comfort, few options are better than the Escalade. This week, our tester was a long-wheelbase Escalade ESV. That means substantially more room both behind the third row and with the seats folded. The Premium Luxury trim sits in the middle of the lineup, but it still comes with a lot of goodies. Features include a Bose audio system, a digital instrument cluster, a heads-up display, heated and cooled leather seats, a heated steering wheel, tri-zone climate control, Magnetic Ride Control and a stout 6.2-liter V8. Options include upgraded leather for $2,000 and polished 22-inch wheels for $600. All in, this Escalade was just shy of $100,000. Editor-in-Chief Greg Migliore: The Escalade is arguably Cadillac's best vehicle. It's a bold, body-on-frame SUV that feels decadently all-American. The Escalade is still contemporary even though it's been years since the ute has had a major redesign. I enjoyed a couple nights in this luxury bruiser. The V8 is powerful, and the 10-speed is a smart improvement. The command seating position is always welcome for me. The interior is nicely laid out, and the materials all look and feel upscale. Not a huge fan of Cadillac's touchscreen (no longer officially called CUE), but it seems to be getting better or I'm getting used to it. Love the Escalade's exterior design. It's dramatic, imposing and gives Cadillac something that's a true style-leader. All that being said, I'll be interested to see how Caddy iterates the Escalade. The Lincoln Navigator is an excellent product and a worthy adversary. Cadillac would be wise to keep its SUV flagship fresh. Senior Editor, Green, John Beltz Snyder: I was not excited to get into the Escalade. This is really not my cup of tea. I used to love the Chevy Suburban, but that fondness has languished as my tastes evolved as these huge vehicles have modernized, losing the charm that drew me to them when I was younger.

GM recalling another 2.7 million vehicles in five separate campaigns

The recalls keep rolling in from General Motors, evidently keen to avoid repeating the mistakes of the ignition-switch debacle and clean house. This time they're all coming at once, with five separate recalls announced together covering approximately 2.7 million vehicles.
The largest of the five actions involves over 2.4 million units of the previous-generation Chevrolet Malibu and Malibu Maxx, Pontiac G6 and Saturn Aura in order to fix brake light wiring harness, which have been found to be susceptible to corrosion. The recall is separate from the 56k Aura sedans which GM recently recalled over faulty shift cables, not to mention the previous massive recall of 1.3 million vehicles - some of them the same models - but appears to have resulted from the National Highway Traffic Safety Administration investigation that started with the G6 almost a year ago.
The second-largest campaign involves the 2014 Chevy Malibu, specifically those fitted with GM's 2.5-liter engine and stop/start system, approximately 140,000 examples of which has been found to have problematic brakes. The issue does not appear to be connected to the recall of 8k Malibu and Buick LaCrosse sedans (also involving brake woes) which we reported upon last week. Four crashes have been reported in such models, but GM admits it's not yet clear if the problem was a contributing factor in the accidents.
