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.

Chevrolet Suburban Luggage Test: How much fits behind the third row?

From the very beginning of doing these luggage tests, I specifically had no intention of doing one for the Chevy Suburban or any extended-length full-size SUVs. Quite simply, there was no question that my six suitcases were going to fit behind the third row. And not only that, I was pretty confident there'd be a ton of space left over, much as there is in mid- and full-size two-row SUVs.  And yet, you know what vehicle I've received more requests for cargo-related information about over the years? That's right, the Chevrolet Suburban. Sure, it's not exactly BTS fan mail volumes, but it's more than anything else. Apparently, people want to know how much fits in the back of a Suburban (or GMC Yukon XL ... or Cadillac Escalade ESV). So, when a Suburban popped up in the press fleet I decided to finally give the people what they want.  As a reminder, this is the amount of cargo space behind the THIRD row of a Suburban. Chevrolet says this is 41.5 cubic feet, and it sure looks like it.  For the record, the most stuff I've ever put into the back of a three-row vehicle is a Honda Odyssey, which has 32.8 cubic feet of space. I never did another minivan after that, for reasons effectively described above. And no one has asked for it. Now, because I'm greedy, I lifted up the floor to see if there's any underfloor space. Wow, there is! Theoretically, it could lower the floor a bit and allow for even more stuff, but the floor's hinges don't allow it. Unlike those in a BMW that can be propped into an upright position, these'll just drop the floor back down again. That's OK, I won't use this then. Let's get to the bags. As with every Luggage Test, I use two midsize roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two black roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller green roll-aboard that fits easily (23L x 15W x 10D). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D). So yeah, it all fits. No surprise there. In fact, there's even more room leftover than I anticipated.  Let's go to the extra (and imaginary) items, then! First up, the trusty 38-quart Coleman cooler. This added to my bags, plus maybe a duffle bag, is what big "compact" SUVs like the Kia Sportage and Toyota RAV4 can manage.

Sunday Drive: An automotive flavor for every taste

Last week was flush with interesting new vehicle debuts, led by the new 2019 Hyundai Santa Fe. This crossover is entering straight into the heart of one of the world's most competitive automotive segments, and it's doing so with a fresh sense of style and a brace of new technologies. Our readers are clearly intrigued – the Santa Fe was the biggest news story of the last week on these online pages. It's fitting that a crossover generated a lot more interest than a traditional wagon, though we don't really have to be happy about it. Still, the completely new, fully redesigned Volvo V60 is worth taking another look at. First of all, it's pretty, in a traditionally Scandinavian way. Second, it's quick, with a 0-60 time of as little as 4.8 seconds. And finally, it's practical, with all kinds of room for cargo without the dynamic penalties of an unnecessary lift kit. Moving on from new vehicle debuts, we took another long look at the Honda Ridgeline. It's definitely a non-conformist pickup truck, based not on a body-on-frame platform but on a more carlike unibody design. That means it can't tow as much as some other trucks, but it also means the Ridgeline drives better than any of its more truckish competitors. It's the Swiss army knife of pickup trucks. Rounding out our coverage from last week are three sets of spy photos, each showing the interior of a hotly anticipated new model. One is a truck, one is a crossover, and the last is a sportscar. All of them are worth another look.
