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.

Expect greater differentiation in GM's next-generation SUVs

General Motors says its next-generation Chevrolet Tahoe, Suburban, GMC Yukon and Cadillac Escalade models will offer shoppers improved interior differentiation. Car and Driver recently caught up with Chris Hilts, GM's creative manager of interior design, who said that the cabins will all feature unique instrument panels, consoles, center stacks and switchgear moving forward. Apparently GM is now aware that consumers may be bothered by the fact that today's $85,000 Escalade has effectively the same cabin as a $45,000 Tahoe. Hilts says SUV buyers want more refinement than their pickup purchasing counterparts - and those same buyers also want their SUVs to have more exterior differentiation between the company's Silverado and Sierra pickup lines. Shocking.
That all sounds good to us, but we've heard this song and dance before. GM made big waves about how different the new-for-2013 Silverado and Sierra would look from each other, but judging by what we've seen so far, GM's stylists are painting in shades rather than with the full spectrum.

Buy a Mosler Twinstar, the V16 Cadillac you almost wanted [w/video]

Cadillac was once famous for opulent, V16 luxury vehicles, but this bizarre 16-cylinder 1999 Eldorado that's for auction on eBay Motors isn't much like its ancestors. Dubbed the TwinStar, this beast features a Northstar V8 with 275 horsepower to drive the front wheels and a second Northstar with 300 hp is in the trunk to spin the rear axle. Each mill has its own four-speed automatic gearbox, and the result is a total of 575 hp of all-wheel drive fury in an incredibly weird package. The TwinStar's interior and exterior certainly don't hide the odd powertrain setup. To fit the engine in the trunk, the builders pushed the rear wheels further back and lengthened the wheelbase. There are also scoops low on each side to funnel air to the V8. Inside, there's a second ignition on the side of the center stack, and a digital instrument cluster replaces the glove box. It's sure to confuse any passenger you can convince to take a ride in this thing. Mosler, the supercar company known for models like the MT900, built five TwinStars, according to the auction. The seller links to the original review by Car and Driver, and the magazine noted that the sensation of the two engines working in tandem was rather odd. However, the TwinStar was a capable performer and ran to 60 in 5 seconds in its test. If you want to start your new year with the oddest vehicle possible, the TwinStar's auction sits at $5,600 with the reserve not met as of this writing, and it ends January 2, 2016, at 8:00 PM ET. If you can't wait that long, the dealer lists the car online for $39,900. There's also a spirited conversation on Bring a Trailer about this automotive oddity.
