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.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

GMC Hummer EV hits Neiman Marcus Christmas catalog for twice the price

This winter season, Nieman Marcus is getting into the true meaning of Christmas by offering a bunch of seriously expensive stuff in its annual holiday catalog. There's usually at least one automotive offering, and this year it's a 2022 GMC Hummer EV Edition 1 for an eye-watering $285,000. That's $172,405 more than the regular Edition 1 crab-walker, which is priced by GMC at $112,595. And what does one get for more than 2.5 times the cost of the most expensive electric Hummer? Well, hold your 1,000 horses, because this isn't just any Hummer EV Edition 1. No, it's a one-off Barrett-Jackson Hummer EV Edition 1. The interior of this Barrett-Jackson edition Hummer has been "curated" by Craig Jackson himself. And by curated, they mean it has a bunch of red trim everywhere and is garnished with a Neiman Marcus logo. Aside from that, there is nothing appreciably different about it. No performance upgrades, no special paint job. You do get an electric charging station at home, though, which might be the most useful addition to this whole enterprise. If that's not worth the price of an entire 1.5 extra Hummers to you, there's more. You get two VIP passes for the opening gala of the Barrett-Jackson auctions in exotic Scottsdale, Ariz. During the auction, you'll get access for two to Carolyn and Craig Jackson's personal skybox from where you can watch 1,500 cars trade hands. But don't get too comfy, because at some point you'll be invited on stage to receive your Hummer EV in front of a gaggle of inebriated fishing boat dealership owners. Oh, and you'll also get to bang the little auction hammer. You can pair the Hummer with other gifts in Nieman Marcus' "fantasy" catalog, like a $6.1 million dollar diamond ring. However, if you go with the $395,000 Great Gatsby-style roaring '20s party, make sure it doesn't end with the 9,000-pound Hummer Daisy Buchanan-ing any bystanders.
