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.

Cars with the worst resale value in 2022

Car values are all over the map right now. Used vehicles that were worth a small fortune earlier this year are now coming back to Earth, but the new vehicle supply remains tight. Prices are still elevated overall, but some models have seen more severe price drops. Depreciation strikes almost every model, supply constraint or not, though a few vehicles are leading the way. New research from analytics iSeeCars found that a handful of cars depreciated more than 50 percent over five years, with the BMW 7 Series dropping 56.9 percent and an average price cut of $61,923 over that time. The vehicles with the highest depreciation — or worst resale value — over five years: BMW 7 Series: -56.9% Maserati Ghibli: -56.3% Jaguar XF: -54% Infiniti QX80: -52.6% Cadillac Escalade ESV: 52.3% Mercedes-Benz S-Class: 51.9% Lincoln Navigator: -51.9% Audi A6: -51.5% Volvo S90: -51.4% Ford Expedition: -50.7% iSeeCarsÂ’ research showed that midsize trucks, sports cars, and fuel-efficient vehicles were slowest to depreciate over five years, while itÂ’s clear that luxury brands tend to lose value much faster. As iSeeCarsÂ’ Executive Analyst Karl Brauer explained, used buyers donÂ’t value high-end vehiclesÂ’ features as much as the first owners, so resale values tend to be softer. The tech and options that made the cars so expensive and appealing new donÂ’t add the same value on the used market.

The Nissan Leaf depreciated most among EVs, dropping by 49.1 percent. The average EV depreciation is 44.2 percent, with the Tesla Model S and Model X sliding in right under the bar at 43.7 and 38.8 percent, respectively. As iSeeCars notes, itÂ’s important to be vigilant when car shopping and not let your emotions win over reason. Shiny new luxury cars look great in the showroom, but you could end up taking a bath when you try selling them a few years later on.

Cadillac confirms Blackwings will get manual transmissions and 3D-printed parts

Cadillac's upcoming 2022 CT4-V and CT5-V Blackwing will be the first GM production cars to utilize 3D-printed technology. In fact, the technology will be featured front and center on one of the cars' most hotly anticipated features — in a decorative medallion atop the shift knob of the manual transmission. Cadillac says that "additive manufacturing" (named as such because 3D printing accumulates tiny deposits of material to create the object) made the manual transmissions possible by reducing costs and waste. Aside from the medallion, the cars will employ two 3D-printed two HVAC ducts and an electrical harness bracket. "[The manual transmission is] something we know V-Series buyers want and itÂ’s something we knew we had to have, so we used innovative processes to make it happen,” said Cadillac performance variant manager Mirza Grebovic. Speaking of which, Cadillac commissioned a Harris Poll survey about manual transmissions and received some interesting results. For example, 66 percent of American adults surveyed know how to drive manual, and 55 percent said they've owned a standard shift car. Of those who don't, roughly 40 percent are either somewhat or very interested in learning. Interest is highest among two key demographics, 64 percent of those earning $75,000 or more in annual household income, and 62 percent of those ages 18-34. The findings seem to contradict what many automakers have said about lack of interest in manuals, with some declaring a sub-1 percent take rate when manuals are offered. Perhaps with a performance-oriented car such as the V-series, buyer preferences change. The mix of old school gearboxes and new school manufacturing techniques will result in what looks like a very potent car on paper. The CT5-V Blackwing is rumored to be powered by an updated 6.2-litter V8, while the CTS-4 Blackwing is said to be motivated by a turbo six. Neither will use the twin-turbo 4.2-liter V8 of their namesake, but they should prove to be worthy successors to the CTS-V and ATS-V. Related Video:
