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.

2022 Cadillac CT5-V Blackwing will get carbon fiber seat backs

Cadillac is putting the finishing touches on the 2022 CT5-V Blackwing, the high-performance sedan that will pick up where the CTS-V left off. It announced the model will be available with carbon fiber front seat backs. Presumably found on the list of extra-cost options, the weight-saving carbon fiber seat backs will stand out with a book-matched design and a laser-etched V-Series logo that will remind the passengers sitting in the back that they're not riding in a regular CT5-V. Interestingly, Cadillac noted the seats will also boast "other customer-centric innovations and features" that will be detailed closer to the sedan's on-sale date. Chairs are hardly on the front lines of automotive innovation, so we're looking forward to learning more about what Cadillac has in store. Drivers will have carbon fiber in front of them, too, because the multi-function steering wheel's bottom spokes will be made with the composite material. Cadillac hinted the sedan's top speed will lie in the vicinity of 200 mph. 2021 Cadillac CT5-V Blackwing spied View 15 Photos Nearly everything else we know about the CT5-V Blackwing comes from a diverse selection of rumors, industry murmurings, and spy shots. We learned earlier in 2020 that it might receive an updated version of the 6.2-liter V8 that powered its predecessor, not the 4.2-liter Blackwing engine it's named after, and leaked images strongly suggest a manual transmission will be available, though we assume Cadillac will also offer an automatic. It might be a six-speed stick, or Cadillac could use a version of the Chevrolet Corvette's seven-speed manual. Our questions will be answered when the 2022 Cadillac CT5-V Blackwing finally makes its debut. It's scheduled to go on sale in the summer of 2021, so its unveiling is likely a couple of weeks away, and Cadillac warned availability will be limited. The smaller CT4 which replaced the ATS, is also in line to get the Blackwing treatment.
