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.

Next-gen GM SUVs caught wearing new boxy bodies [w/video]

We recently drove the brand-new 2014 Chevrolet Silverado and found it to be vastly improved compared to the outgoing model. And now that The General's pickup trucks have been squared away, it's time to focus our attention onto their passenger-friendly companions, the Chevrolet Tahoe and GMC Yukon (above).
Our spy photographers have passed along a huge smattering of photos (and a video), showing the new SUVs out testing. Both the short- and long-wheelbase models were spied, and while the overall shape of the vehicles hasn't changed all that much, we expect the updates to be substantial. In addition to new powertrain options, like GM's new small-block V8, we expect the interiors of both SUVs to get massive makeovers, providing better materials throughout their cabins and quieter, more refined environments. We even hear that some trick new suspension developments may be in store for upper-end models.
Visually, these spy shots allow us to see a couple of new details on the SUVs' front and rear fascias, including LED running lamps on the Yukon and some interesting LED taillamp treatments. Of course, the obvious third party missing from this set of photos is the Cadillac Escalade, but as we reported earlier, GM is working to further differentiate the 'Slade from the rest of the fullsize SUV lineup, and is working to make the new model "much less ostentatious."

2018 GMC Terrain Drivers' Notes Review | Summon the Druids, it's a better Equinox

We've had plenty of time in the all-new Chevrolet Equinox, testing it with all three of its available turbocharged four-cylinders: the 1.5-liter, the 2.0-liter performance upgrade and the diesel fuel economy upgrade. Finally, however, we get a turn behind the wheel of its brother from a different corporate mother: the 2018 GMC Terrain. This duo is certainly one of the most disparate pairings in GM's long badge-engineering past, with virtually no visual similarities inside and out. They're even less similar than the last Equinox-Terrain, which themselves were a far-cry from the Blazer-Jimmy days. They're largely the same under the skin, however, including their selection of engines. For the 2018 Terrain, we sampled the 1.6-liter four-cylinder turbodiesel good for 137 horsepower and 240 pound-feet of torque. It's an unusual powertrain to be sure, as no other compact crossover SUV in this country offers one (though Mazda has been threatening to do so for years now), but boasts an EPA-estimated fuel economy rating of 28 mpg city, 39 mpg highway and 32 mpg combined with front-wheel drive. It's basically the same with all-wheel drive. The as-tested price of the SLT Diesel was a rather hefty $39,605. It did, however, have most options, including the Infotainment Package II and Driver Alert Package II that together include all the extra entertainment and safety gadgets. Contributing Editor James Riswick: Let's be honest, the main difference between the 2018 GMC Terrain and its Equinox sibling is the way they look. As such, I can definitively say I prefer the Terrain. It's far more cohesive and better proportioned than the rather dumpy Equinox. It also avoids the garish over-adornment of the last Terrain even if the floating roofline D pillar has passed its expiry date. I think the interior looks better too. As for the way it drives, the 2018 Terrain demonstrates great improvements from one generation to the next. The steering in particular is greatly superior in its feel and feedback. Body motions are also kept nicely in check. Is it a Mazda CX-5 or Ford Escape beater? No, but it's far more confidence inspiring now. So that's the good. Now, the extremely bad. This diesel engine vibrates so much I can't imagine anyone taking one for a test drive and choosing it over the 1.5-liter gasoline turbo. You feel it through the wheel, the pedals and the seat of your pants constantly. It's particularly bad when stopped and even present when just cruising on the highway.
