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.

Cadillac president reveals XTS sedan refresh, flagship vehicle plans

Update: The second paragraphed has been changed from the original text to make it clear that de Nysschen, not Autoblog , claimed the report by The Detroit Bureau is inaccurate. Cadillac has been on a tear ever since the automaker poached Johan de Nysschen from Infiniti, becoming a more profitable automaker while delving deeper into the luxury market. While some reports indicate that Cadillac may be limiting its lineup, de Nysschen just put everything out in the open. In the comment section of an article by The Detroit Bureau that claimed Cadillac would cut its lineup down, de Nysschen stated the report was inaccurate and outlined the automaker's future. The Cadillac CEO wrote "Some of what you report is correct, some incorrect, most is conjecture." A Cadillac spokesperson confirmed that de Nysschen did write the comment, but did not comment on any of the details. The Detroit Bureau's Paul Eisenstein told Autoblog that he stands behind the information in the report. In any case the most interesting tidbit in de Nysschen's comment is the major refresh for the Cadillac XTS. The news directly contradicts previous reports that indicated the XTS would be killed off by 2019. In Cadillac's pursuit to add some space between it and GM, the XTS was expected to get the axe in favor of more profitable vehicles. The sedan, which was introduced in 2012, shares its underpinnings with the latest generation of the Chevrolet Impala. To the contrary, Nysschen stated that "We ARE planning a major refresh for XTS." What the major refresh will bring the aging sedan is still a mystery, but the vehicle isn't dying. The move to keep the XTS in its lineup is a bit of a surprise as Cadillac has filled its lineup with track-oriented sports cars, rear-wheel-drive sedans, and extravagant crossovers. The boat-like XTS with its front-wheel-drive layout and available all-wheel-drive system sticks out like a sore thumb, even if it were to receive a major overhaul. The only real explanation is that Cadillac hopes the vehicle will still appeal to its old-school customers that are unwilling to compromise interior space and ride quality. In our most recent review of the XTS, we thought the luxurious sedan was a great long-distance cruiser, but not a talented sports car – no surprises there. It's unlikely that Cadillac will focus on driving pleasure with the refreshed XTS, focusing instead on pure comfort and luxury.

The 2021 Cadillac Escalade's triple curved OLED screens are gorgeous

The centerpiece and crown jewel of the 2021 Cadillac Escalade is the triple OLED screen setup facing the passengers. It’s an imposing cowl with 38 inches of screen real estate in total, and itÂ’s a Cadillac Escalade-exclusive piece of technology. An interesting and unique feature like this has the potential to set Cadillac apart from the stiff competition in the luxury space.  Its appearance is just like that of the Cadillac Escala concept. We donÂ’t often get to see interior concepts carried into production, so thatÂ’s exciting on its own. The layout consists of a 16.9-inch touchscreen infotainment system, a 14.2-inch instrument cluster and a 7.2-inch touchscreen to the left of the cluster. All of the screens are curved and use OLED technology, which is commonly used on the screen of your Android phone, iPhone or TV. It allows for the deepest blacks, best contrast ratios and extremely vivid colors. In short, an OLED screen is going to look better than an LCD screen, and thatÂ’s why Cadillac is using it. We sat down with a few folks who could tell us more about it. Phil Kucera, Cadillac interior design manager, gave us some background on the decision to implement this tri-screen layout. “To be honest with you, it was a high-end leadership decision,” Kucera says. “There was a lot of, 'Hey maybe we donÂ’t put that on the base level. And why do you have to use OLED?' Because OLED is not the cheap way to go. So the fact that it stayed that size and remained OLED Â… I would bet that youÂ’re going to see other people doing something like this. There was a real push to try and get here first.” Sounds like the screen could have ultimately been a victim of cost-cutting measures. WeÂ’re glad it made it into production, because it looks promising. Sameer Gupta, GM's engineer manager responsible for infotainment, walked us through the new digital landscape. If you didnÂ’t like the old Cadillac software from before, youÂ’ll be happy to learn that this system is a completely new user interface, sharing nothing with any software before. Gupta told us that this is “a complete first-of use of this interface.” “When we started doing the system, we envisioned a system that had rich graphics, but was also simple and adaptive,” Gupta told us. After spending some time poking around in an Escalade, we can report that the new menus are full of rich graphics, pleasing animations and snappy transitions.
