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 mulling CTS Coupe successor after all

The 2014 Cadillac CTS made a big splash last week at the New York Auto Show, but now that we've seen the sedan, we can start to wonder about whether coupe and wagon versions are in the cards. According to Edmunds, Cadillac is at least considering bringing back the CTS Coupe for a second generation, which seems like an even better chance since the brand's global marketing director, Jim Vurpillat, was quoted as saying that the car was the top-selling luxury coupe in the industry.
Of course, this goes against reports we heard last year that Caddy's coupe and wagon would live on just not under the CTS name, but the interview with Vurpillat has us hopeful for a next-generation CTS Coupe. If it does come to fruition, we would expect the new two-door to have a largely unique exterior design like the current CTS Coupe, to echo that of intended rivals like the Mercedes-Benz E-Class Coupe and even the high-dollar BMW 6 Series.

Cadillac teases production ELR ahead of Detroit Auto Show

General Motors has just confirmed that the 2014 Cadillac ELR will make its official debut next month at the 2013 Detroit Auto Show. We've already seen the ELR testing earlier this year using the same range-extended electric drive system as the Chevrolet Volt, and based on the shadowy image above, we're happy to see that the coupe's styling has stayed pretty true to 2009 Converj Concept.
The two-door ELR will be built alongside the Volt at GM's Detroit-Hamtramck plant starting later next year. Aside from this info, Cadillac has remained tight-lipped on the specific details of the car. But all that will all change on January 15.
Until then, all we have to offer you is the press release posted after the jump.
