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 ATS-V and Mercedes-AMG C63 S pitted Head to Head

Our favorite (and only) Autoblog-alum-turned-Motor Trend staffer is back with another Head to Head video, this time pitting the Cadillac ATS-V with the Mercedes-AMG C63 S. This performance machine shootout is ostensibly a way to figure out which of these new super sedans will earn the right to go toe-to-toe with the undisputed champion of its segment, the BMW M3. In reality, it's just a really good excuse to put three of the hottest sedans on the market on video at the same time... and there's certainly nothing wrong with that. Jonny Lieberman spends time in each of the two new challengers on the road, picking apart their powertrains, chassis and driving dynamics on the kinds of twisty roads drivers of these cars will relish. Then, he hands the keys off to Randy Pobst, who sort of acts as an unmasked version of a certain tame racing driver, except that he talks and has a personality. 0-60 and quarter-mile times are equated, braking performance is measured and scores are tallied before the two sport sedans end up at Willow Springs raceway. Interestingly enough, the car that proves (just slightly) faster at the race track isn't the car that wins the comparison. Curious? We're not going to spoil it for you. Check out the video, above. Then, for more action of these two machines, check out the videos just below.

New Cadillac ELR ad more educational, less controversial than 'Poolside'

Cadillac's first TV commercial for its ELR plug-in hybrid, Poolside, was a smash hit, in that a lot of people saw and talked about it. The 60-second spot didn't say the car was a plug-in, took potshots at the work ethic of all non-Americans and has raked in over a million views on YouTube (you can add one more here). Caddy's new ELR video will get a lot less media attention, but that's exactly the point. Cadillac claims it was happy with the way actor Neil McDonough strutted his way into the controversial ELR discussion. This time around, though, the coupe gets promoted in a more traditional way: with information about the car and what it can do - you know, drive on electricity, capture braking energy into the battery, go further on gas power when needed, those kinds of things – courtesy of GM's executive chief engineer for electrified vehicles, Pam Fletcher. The tone of the video has not been changed because of the Poolside controversy. David Caldwell, manager of Cadillac communications, tells AutoblogGreen that the new video is not destined for TV and is completely different because it's meant for a different audience. "It doesn't have any direct relation to Poolside," he says. "TV advertising is not necessarily the heart of marketing something like the ELR. Notwithstanding the fact that we had a very thought-provoking ad [laughs]." "We definitely have a need to communicate what the ELR is" - Cadillac's David Caldwell The way you reach out to people via the web is different than the mass-media techniques used in spots like Poolside during big TV events (it aired during the Winter Olympics). The two video spots are different because you need to offer different information in different ways, for example having an ELR website as well as an iPad filled with ELR information at the dealership. For Cadillac, TV is "not going to be the predominant methodology," used to sell the ELR, Caldwell said, "the web is closer to what you need to do to reach people. We definitely have a need to communicate what the ELR is. It's not television advertising at all." Caldwell said a handful of other short videos similar to the new one will go live in the near future, showcasing design and powertrain aspects of the car. Keep an eye out for them – just don't look for them on TV. You can watch the new video below.
