Akerson says Cadillac will get a larger sedan within two years

It seems that during a recent affair showing off the 2014 Cadillac CTS, General Motors CEO Dan Akerson confirmed reports regarding a new Cadillac flagship sedan. According to USA Today, which Akerson was visiting, he said that a sedan larger than the XTS would debut within the next two years.
This matches up with what we heard earlier in the month about a Cadillac model that will go up against the BMW 7 Series and Mercedes-Benz S-Class (not a pricier, low-volume sedan also discussed in that article). But this is the first time a high-profile executive name has been attributed to such a report, and the first time a broad timeframe has been mentioned. This article adds that the unnamed car will be rear-, and all-wheel drive with a platform "loosely based" on the new CTS, with styling closer to that car than recent Cadillac concept vehicles. The XTS will continue production of course, as well.

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.

2020 Cadillac CT5 in New York: 7 questions with the chief engineer

Cadillac revealed the 2020 CT5 at the New York Auto Show, and we decided to sit down and have a chat with chief engineer Mike Bride to learn more about the car. You can read our reveal post here to get the full download, and then read on below to learn a bit more. Cadillac is still rather coy about any performance model to spawn from the CT5, but things appear to be looking up after our conversation that you can read below. Q: What's the driving nature of this car? Should we expect something similar to the CTS and ATS? A: Yes, you can see it's built off the rear-wheel-drive architecture. Our goal was to retain all of that fun-to-drive nature. Direct steering feel, responsive handling. Going forward, we ask how we can continuously improve, and that was really about driving more sophistication in the ride, a much more mannered car that's better for impact harshness and rolling isolation, really provides comfort when you want comfort over tire strips and heaves in the road. Really getting that level of isolation, but not compromising that handling and direct steering feel of the Cadillac sedans we've grown accustomed to. Q: How is this car different from the CTS underneath, and other Alpha platform cars? A: I would say this is a major revision. A lot of new parts, a lot of new part numbers, a significant evolution. In the suspension space, the links are all new, and there's been a lot of work done in isolation, so the bushings and strut mounts are all new. We've evolved the Alpha platform to now get the ride control and road isolation, the comfort aspects of it all. There are a lot of structural improvements like a changed wheelbase, an evolution in rear foot-swing and foot space from the fuel tank area to get in and out of the car better. As we developed this structure, it was about overall structural body stiffness, and impedance at the chassis attachments to really get that level of isolation from road inputs. We try to have a calm floor, a steering wheel that doesn't vibrate, and quiet to the driver's ear. Those were the paths we went after to really drive the structure to the right stiffness requirements, structural integrity, a lot of development into suspension bushings, tuning elements, strut mounts. We have a new damper technology, a ZF damper. It has MVS damper technology. It's a multi-valve system that provides less harshness from an NVH standpoint and a great optimization balance of motion control with ride inputs.
