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.

2021 Cadillac Escalade ESV officially shown for the first time

When Cadillac originally debuted the 2021 Escalade at the beginning of the year, it held back on photos of the long-wheelbase ESV version of the truck. GM told us the ESV would be revealed in full at the New York Auto Show this year, a show that was promptly postponed due to coronavirus. However, that hasn’t exactly stopped us from seeing the ESV anyway. One of our spy shooters managed to capture a trove of images, showing the ESV without any camouflage. You can scroll through those below. 2021 Cadillac Escalade ESV Sport View 20 Photos At the top of this post sits the one official Cadillac image of the ESV — the other photos are from Cadillac's online visualizer tool. What a grand reveal! The Escalade pictured in front is the Platinum Luxury trim, and the one behind it is the Sport (or Sport Luxury Platinum). Just like we spied before, the main styling differences between the regular Escalade and ESV are minimal. Cadillac extended the rear door and massaged the C-pillar — itÂ’s thicker and leans at a sharper angle. Even before revealing the car in photos, Cadillac gave us all the specs. That was enough for an on-paper comparison between it and the Navigator, including the long wheelbase versions of both. The ESV is 15.9 inches longer than a standard Escalade, allowing for more third row legroom and additional cargo capacity. In other news, Cadillac says orders for the 2021 Escalade can be made today via its website. The system will put you in touch with a dealership to place your order. Those orders will begin arriving in dealerships this fall, according to CadillacÂ’s current plans. You can check out full model line pricing in our post detailing it all here. Related video:

First Cadillac ELR rolls off the line

Gearing up for the Belle Isle Grand Prix this weekend, General Motors invited some of the Chevrolet and Cadillac racecar drivers out to its Detroit-Hamtramck assembly plant. While there, the racers - including IndyCar Driver and Chevrolet Volt owner, Simona De Silvestro - witnessed the very first 2014 Cadillac ELR to roll off the assembly line.
These vehicles are not destined for customers, however, but instead pre-production units will be used by engineers for testing purposes. Actual production of ELR consumer models is expected to commence closer to the end of this year. As a refresher, this range-extended electric Cadillac shares much of its powertrain with the Volt but will have a sportier coupe design inspired by the Converj Concept. De Silvestro manged to snap a few images of here own, which you can see in the gallery below.
