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.

Hotter Cadillac CT4-V prototype spied testing at GM's Proving Grounds

Cadillac already teased us once with the hotter CT4-V and CT5-V at the Belle Isle Grand Prix, but these photos are still the best look yet at what's next for the Cadillac V-Series. The car we're looking at in heavy camouflage here is a high-performance CT4, but we don't really have a name to call it at this point. Cadillac hasn't said, so it could be anything. We'll just refer to it as the faster V, as it's certainly looking a bit more racy than the warmed-over CT4-V already revealed. While the styling isn't drastically different from the CT4-V already out there, the front intake and openings look deeper and more aggressive. The middle, raised section of the hood is a little taller and the whole front-end design looks a lot like the one teased in Belle Isle. This vehicle even appears to have the same mirror design as the faster V. The side sills, quad exhaust tips and wide rear tires lend this prototype an aggressive look, but we did note that it doesn't have the big ducktail spoiler we saw teased previously. Maybe Cadillac is trying to keep a low profile while testing. A keen eye will notice a wild apparatus attached to the front, which would serve as a great jousting pole if you were into that kind of thing. We don't know exactly when Cadillac plans to introduce the faster V machines, but we wouldn't doubt if it happened before the year was out. The ATS-V and CTS-V didn't look wholly different than the pedestrian versions of those cars, and this prototype indicates Caddy may follow a similar pattern this time around. All will be explained from GM soon, but for now, we wait.

Cadillac sells out Lyriq Debut Edition reservations in 10 minutes

Cadillac opened reservations for the 2023 Lyriq Debut Edition electric crossover at 4 p.m. EDT on Saturday afternoon. Anyone could put down a refundable $100 to reserve a buying slot for Cadillac's limited-run first salvo at the brand's all-EV future. At 4:19 p.m., the automaker tweeted that "every Debut Edition has been reserved." According to GM Vice President Rory Harvey, the process took "just over" 10 minutes. First, we'll say "Congratulations!" to Cadillac. Then we'll say: We have no idea what the news means. See, Cadillac has declined to say how many reservations it made available and how many Debut Editions it's building.  We don't know why the crest and wreath brand is being so coy, but we can imagine at least one reason. GM and Cadillac can attract such wild reactions that unless the Lyriq booked an absurdly large number of reservations in an absurdly short time, both brands were going to get flayed by comparisons to other EV makers. Still, since Cadillac's playing the long game with this entire transition to EVs, we wish it had placed its neck gracefully in the guillotine anyway.  The Lyriq Debut Edition that no one can buy anymore unless reservation holders bow out comes with a 100.4-kWh battery pack, a single e-motor on the rear axle putting out 340 horsepower and 325 pound-feet of torque for a range claimed to be "more than 300 miles," a glass roof, 19-speaker AKG audio, heated steering wheel, and 20-inch wheels standard, 22-inchers optional. The only two colors available are Satin Steel Metallic and Stellar Black Metallic. Tech features include adaptive cruise control, HD Surround and Vision recorder, rear camera mirror, and, of course, the 33-inch curved display across the instrument panel. First deliveries for the rakish $59,990 CUV are expected in early 2022. The next order slots will open for standard Lyriq trims in summer 2022. Based on Cadillac's Twitter feed, quite a few internet users wanted to reserve Debut Edition cars but were prevented from doing so. If first reports from the early deliveries are positive, Cadillac might hold onto last weekend's demand until next summer. And not only will the brand have a widely available new vehicle then, it will have a new consumer look. Last year, Cadillac told its dealers what they would need to do with their stores to prepare for the EV era, including spending around $200,000 on EV infrastructure and tools.
