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.

President Trump might get to start his administration in a new Cadillac limo [UPDATE]

(UPDATE: Jalopnik is reporting an unidentified source claimed the new limo would not be featured in today's inauguration ceremony. The source did say however that the limo would join the presidential fleet later this year.) A rumor is going around that President-Elect Donald Trump will have a brand new set of wheels the day he takes office. The Cadillac Presidential Limousine, nicknamed "The Beast," was last refreshed in 2009 and led President Barack Obama's second inauguration-day parade. Cadillac could not confirm any timeline for the new presidential limo, nor could it confirm any specifics about the car nicknamed Beast 2.0. That's as expected, because details on the presidential limo are closely guarded and considered matters of national security. The outgoing original "Beast" limo marked a switch to a custom-built vehicle based on a General Motors truck frame. Previous limos were based on the actual cars they looked like. As we've seen in spy shots, The Beast 2.0 limo looks more like an Escalade SUV or CT6 sedan but is reported to be roughly the same size and shape as the old Beast, which is built on a Chevrolet Kodiak/GMC TopKick medium-duty truck chassis. AutoWeek is reporting that the new limo is set to debut for Trump's inauguration, however those reports could not be confirmed for the reasons mentioned above. The new Presidential car is expected to accommodate seven passengers in conference-style seating in the back like the current version. The Beast isn't meant for road trips, as it is mostly used to ferry the President to and from Air Force One when traveling, or on short trips around Washington D.C. That's good, considering the current limo only gets 3.7 miles per gallon. Along with multiple screens for video conferencing, The next Beast will also definitely include advanced armoring and weaponry. For security reasons, it's impossible to know the extent of those systems, but any vehicle transporting the most powerful man in the world around has to be tough. The entire process of designing and building the Presidential limo is top secret, as the Secret Service figures the less everyone knows about the Presidential Limo, the better. The new Beast, we can safely assume, is likely the safest vehicle in the world. The Secret Service began taking bids on building a replacement in 2014 because integrating all of the required armor is technically challenging.

Cadillac chief says ATS convertible, wagon on the table

What we do know is that the ATS will wear at least one more bodystyle. That comes from Cadillac head Bob Ferguson, who answered "Absolutely" when Automotive News asked him about the possibility of another variant. What we don't know is what that bodystyle or styles will be.
We now have a sedan and coupe ATS, there's supposedly a V sedan coming. After that, a convertible is a likely option given that the man who just became the global product honcho at General Motors, Mark Reuss, admitted to having one already designed in 2012. The decision on it can't get out of the underworld and a wagon is the other option, but the droptop would seem to make the most sense if one considers the competitive set: the BMW 4 Series and Audi A5 convertibles are hot property and Mercedes is bringing a C-Class convertible. Meanwhile wagons are the sentimental utility vehicles that, refusing to die, seem forever destined for life support... CTS Sport Wagon, anyone?
Based on Ferguson's statements, it appears that what Cadillac definitely won't do is play model variant catch-up with the European luxury brands it has spent years hunting down, telling Automotive News, "We want to keep our focus on a limited number of vehicles and do them very well."
