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.

2021 GMC Yukon starts at $51,955, just $100 more than outgoing model

The 2021 GMC Yukon and Yukon XL have prices, and they're bargains considering the upgrades the new model delivers. The base Yukon SLE starts at $51,995 after the $1,295 destination charge, a $100 premium over the current model. The extended wheelbase Yukon XL in base SLE trim starts at $54,695, the same price as the outgoing model. The price for all-wheel drive stands pat for trims that make it an option, at $3,000. Prices for the two-wheel drive Yukon and Yukon XL trim steps are below, with price differences compared to the 2020 models. Keep mind that the new AT4 trim comes standard with AWD, so the AT4 is in a sense closer in price to the SLT and further from the Denali than it appears here: Yukon SLE: $51,995 (+ $100) Yukon SLT: $59,095 (- $810) Yukon AT4: $66,095  Yukon Denali: $69,695 (+ $800) Yukon XL SLE: $54,695 (No change) Yukon XL SLT: $61,795 (No change) Yukon XL AT4: $68,795 Yukon XL Denali: $72,395 (+ $600) The drop in price on the Yukon SLT is in comparison to the 2020 Yukon SLT Standard Edition trim, not the lower-spec SLT trim. The new Yukon comes in at $1,700 more than the 2021 Chevrolet Tahoe, the same price difference in effect between the Yukon XL and Suburban. The standard Yukon is powered by a 5.3-liter V8 with 355 horsepower and 383 pound-feet of torque, the same specs as found in both the Tahoe and Suburban. The Yukon Denali trims, as with the High Country trims on the Chevy twins, outdo the 5.3-liter with a 6.2-liter V8 making 420 hp and 460 lb-ft. Both engines shift through a 10-speed automatic. Stuffing a Yukon XL Denali with options can take the MSRP beyond $80,000, thanks to available features like the panoramic sunroof, rear seat entertainment, air suspension, and Magnetic Ride Control Suspension.   We're still awaiting pricing for the coming 3.0-liter Duramax inline-six with 460 pound-feet of torque, which we expect closer to the on-sale date for the new full-sized SUVs.  Related Video: This content is hosted by a third party.

GM recalling Silverado and Sierra HD diesel pickups over fuel gauge follies

General Motors is recalling 9,733 of its heavy-duty twins over concerns with their 6.6-liter diesel engines and dual fuel tanks. The recall covers some Chevrolet Silverado HD and GMC Sierra HD pickups from model years 2012 and 2013, although the exact dates that the recalled trucks were built isn't specified. There's also no mention of how many models come from Chevrolet and how many are from GMC.
The problem rests with the transfer pump responsible for moving fuel from the rear tank to the front tank - it could fail, resulting in an inaccurate fuel gauge. It hardly requires explaining, but a faulty fuel gauge could leave drivers in a situation where they run out of diesel.
GM will begin notifying customers of affected vehicles, who will be asked to report to their dealers for a free replacement transfer pump.
