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.

2016 Cadillac CTS-V prepares to kick ass, take names

Some stories write themselves. This post on the North American International Auto Show debut of the 2016 Cadillac CTS-V is one of them. This 200-mile-per-hour sedan pilfers the 6.2-liter supercharged V8 from the Chevy Corvette Z06, and puts it to the same tire-devastating effect, offering up 640 horsepower and 630 pound-feet of torque. An eight-speed automatic – please join us in a moment of silence for the dearly departed manual CTS-V – then dispatches the force-induced thrust to a very large, sticky set of Michelin Pilot Super Sport tires. To ensure the CTS-V can tear your face off with lateral Gs as well as accelerative Gs, Cadillac stiffened the car's structure by 25 percent, fitted magnetic ride control and fitted the aforementioned tires. Beyond the mechanicals, a substantial rear spoiler, front splitter and diffuser improve grip through aerodynamics. Keeping drivers pinned during all this tire shredding and face tearing is the task of meaty, two-piece Recaro sport seats, which are found in a luxuriously appointed cabin, complete with 4G LTE connectivity, a Bose stereo and Siri Eyes Free. There's even a Performance Data Recorder, which will be on hand to record your miscues if (or perhaps when) the car's extreme abilities outpace your own talents. Take a look at our array of live images from the CTS-V's official debut at the 2015 Detroit Auto Show.

6 luxury car brands to watch in 2024

2023 was a healthy year for the auto industry, and even with incentives returning and dealer lots filling up, there's plenty to like about the market if you build luxury automobiles, and we expect 2024 to be more of the same, which makes luxury-segment rivalries all the more interesting. Top luxury car brand rivalries? Well, that sounds downright uncivilized. But we know better, don't we? And when every quarterly sales update is an opportunity to remind somebody else that they bought the wrong status symbol, well, who can resist? Certainly not the diehard customers who fly their favorite brands' banners high.  Read more: Auto sales: Industry records best year since 2019 Read more: 2023 auto sales and 2024 preview: Ford Bronco vs. Jeep Wrangler This is a tricky segment to define, but essentially, we're looking at luxury car brands with depth to their portfolios and dealerships that exist to attract real-world customers. The Bentleys, Rolls-Royces and McLarens of the world are luxury cars, certainly, but we're more concerned with brands that have a bit more mass appeal — manufacturers who treat supply constraints as fiascos rather than features. If you disagree with our selections, feel free to let us know in the comments.  And since we're mostly concerned with finishing order, the luxury brands and totals featured here may change as new data come in throughout 2024. Due to the wild swings of the past several years, we're treating 2023 as the baseline by which we'll measure sales performance. And rather than rank brands vs. their finishing order in 2022, when supply-chain and inflationary issues still played havoc with sales figures, we're starting 2024 off with a clean slate.  The mainstream luxury segment is always a dogfight, but with their varied approaches to electrification all of the major luxury brands are in the midst of reshaping the premium landscape. Who is doing it right? Well, according to U.S. shoppers, the usual suspects are up to their old tricks.
