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.

GM's Mark Reuss explains why a performance Cadillac ELR-V won't happen

Hey, I've got enough things to worry about. That's one interpretation of General Motors executive vice president Mark Reuss' response to a question posed by Driving the Nation about the recently-introduced Cadillac ELR plug-in hybrid. Reuss said GM will "definitely expand the tuning envelope" for the ELR. The question was whether GM would consider adding magnetic ride control to the quite-powerful-for-a-plug-in Caddy, creating an "ELR-V" model in the process. Reuss' non-answer: "Good question, can't really answer that," but then elaborated that magnetic ride control uses up "a lot" of power otherwise spoken for in terms of providing the longest electric-only range possible. Interestingly, he did add that GM will "definitely expand the tuning envelope" for the ELR, as you can see in the video below. With the model retailing for north of $75,000, fewer than 60 percent of US Cadillac dealers were carrying the ELR as of last month and just 99 ELRs were sold during the first two months of the year. In an effort to sell more vehicles, GM said in January that it would offer the ELR for a 39-month lease for $699 a month for qualified lessees and with a $5,999 down-payment required.

Such Sweet Sorrow: Cadillac's CTS-V gets an Irish wake

As the saying goes, all good things must come to an end. The honkin', stonkin' second-generation CTS-V, powered by Cadillac's brawny supercharged 6.2-liter V8 has been a very good thing. And now that the 500 final coupes – the only CTS-Vs designated 2015 models – have been built (just five remain unsold as of this writing), it is indeed a good thing that's come to an end. But Cadillac is not letting 2009–2015 CTS-V go gently into that good night, even as its replacement is poised to debut in just in just two months at the 2015 Detroit Auto Show. Instead, Cadillac invited us to Austin's Circuit of the Americas racetrack for what it called an "Irish wake" for the model that has proven to be one of the quickest and most charismatic models in General Motors' history. If you don't know what an Irish wake is, if you envision storytelling, songs, debauchery and more than a little liquor, you'll be in the ballpark. In this case, though, adrenaline substituted in for the booze, with squealing tires and shrieking V8s providing the singing. The debauchery took the form of an all-you-can-drive lapping of COTA in all three bodystyles – coupe, sedan and wagon – and the stories were told by the grins plastered on our faces all day. First and foremost, we'll miss the CTS-V's perfect balance of luxury and sportiness. Even after six years with no major changes, the CTS-V is surprisingly spry. Certainly, you never forget that it's a heavy thing, weighing in anywhere between 4217 pounds for the manual-equipped coupe to 4424 for an automatic wagon, but with 0-60 times of about four seconds and the ability to hit about 150 mph on COTA's back straight, the Vs remain an absolute hoot on the track. Sure, some of its details – the blocky front fascia shapes and the spoiler on the sedan and coupe models, for example – look a bit dated, but the overall design still looks sufficiently badass. The interior design has worn pretty well, too, and however Cadillac may feel about center stack buttons being so last decade, we favor them over the capacitive-touch madness of today's CUE system. We're not going to bother doing another full review of the car here, but suffice it to say, there is plenty we will miss. First and foremost, will be the CTS-V's perfect balance of luxury and sportiness. Rumor has it that Cadillac will offer the 6.2-liter LT4 V8 in the next generation (we predict about 600 hp), but we hear that the new car will skew more toward luxury than balls-out performance.
