2020 Chevy and GMC HD truck spy shots reveal LED lighting

With Chevy and GMC's 1500 series pickups just starting to roll into dealerships, our attention naturally turns to the Heavy Duty 2500 and 3500 series trucks. We've seen these HD trucks testing already, but thes latest spy photos give us our first good glimpse of the two HD trucks' headlights through some translucent camouflage, and their designs appear very interesting and quite different from each other. The 2020 Chevrolet Silverado HD looks to be getting a striking set of LED lights that flank the grille. A previously released teaser image of the truck shows that the front lighting elements are split by a bulky wing that branches out from a big, upright chrome face, and both top and bottom units seem to incorporate LED slashes. If you look closely at the images, you can easily make out the Chevrolet script cut into the grille's top edge. Amidst a bevy of Chevy test trucks was one lone GMC model in a dually configuration, and the Sierra HD also appears to have some LED accent lighting up front. Unlike the boomerang-shaped Chevy LEDs, GMC's version sports a shoulder-like right angle of light bars. Assuming these are production-level lighting units, it seems the Sierra HD will stick pretty close to the face of GMC's latest light-duty pickup truck. We're still waiting for confirmation on what range of powertrains will be available in GM's next-gen HD trucks, but we're sure there will be both gasoline- and diesel-burning engines on the ordering sheet. We expect to hear official details on the trucks sometime soon.

GMC unveiling 2021 Yukon, Yukon XL on January 14

UPDATE: We received a reply back from a representative at GMC confirming that the new Yukon will be revealed on January 14. The text has been updated to reflect this. General Motors is renewing its body-on-frame SUVs, and GMC's Yukon is next in line to receive a full makeover. It's scheduled to break cover on January 14 alongside the long-wheelbase Yukon XL. It's reasonable to assume we would have gotten our first glimpse at the next Yukon during the 2020 Detroit Auto Show had the event not moved to June. The new date is too close to the model's on-sale date, so GMC will unveil it during a standalone event held in Vail, Colorado, according to GM Authority. We reached out to GMC, and a representative confirmed that is indeed the reveal date for the full-size SUV. Spy shots suggest stylists took GMC's two biggest SUVs in a sharper, bolder direction. Both models share the same front end, which borrows styling cues like C-shaped headlights from the Sierra pickup. Brand-specific rear lights help the Yukon models stand out from their Chevrolet-badged siblings, the Tahoe and the Suburban, which hasn't always been the case. The standard Yukon and the Yukon XL will each grow in size, though there's no indication GMC's naming structure will change to reflect that; Yukon XXL admittedly doesn't have much of a ring to it. While we haven't seen the interior yet, we expect it's getting a generous serving of technology, including a new, touchscreen-based infotainment system. The larger exterior dimensions will clear up more space for people and gear, so average-sized adults will be able to fit in the third-row seats. The range-topping Denali variants of both models will return to satisfy those who crave sumptuousness. The sheet metal will hide much of the same hardware found under the Tahoe/Suburban duo, including an independent rear suspension added in the name of comfort and handling. Powertrain specifications should carry over, too, meaning the entry-level engine will be a 5.3-liter V8 rated at 355 horsepower and 383 pound-feet of torque. The list of options will include a 6.2-liter V8 with 420 horsepower on tap, and we're betting the straight-six turbodiesel available on the Bowtie-badged SUVs will also be offered at an extra cost. Rear-wheel drive and a 10-speed automatic transmission will come standard, and buyers will be able to pay extra for four-wheel drive. The next GMC Yukon and Yukon XL will go on sale halfway through 2020 as 2021 models.

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.
