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.

GM promises to add 20 EVs and fuel-cell cars to lineup, paid for by SUVs

DETROIT — General Motors outlined plans on Monday to add 20 new battery electric and fuel-cell vehicles to its global product lineup by 2023, financed by robust profits from sales of gasoline-fueled trucks and sport utility vehicles in the United States and China. "General Motors believes in an all-electric future," GM global product development chief Mark Reuss said on Monday during a briefing at the company's suburban Detroit technical center. Future generations of GM electric vehicles "will be profitable," Reuss said, but added it was not clear when GM could make all its new vehicle offerings zero-emission electric cars. Regulators in China and some European countries have floated proposals to ban internal combustion engines by 2030 or 2040. "We will continue to make sure our internal combustion engines will get more and more efficient," Reuss said. GM shares were up more than 4 percent in midday New York trading on positive comments from Rod Lache, auto analyst at Deutsche Bank. Automakers, including electric vehicle market leader Tesla, lose money on electric cars because battery costs are still higher than comparable internal combustion engines. The company offered sneak peeks of three EV prototypes: a Buick SUV, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM funds its forays into new technology using a river of cash generated by old-technology vehicles popular with its core customer base in the United States heartland. In comparison, Tesla has burned through an estimated $10 billion in cash and has yet to show a full year profit. GM earned more than 90 percent of its $12.5 billion in pretax profits last year in North America, amid robust demand for its lineup of large sport utility vehicles and pickup trucks. The company's profitable operations in China rely on consumer demand for an expanding lineup of gasoline powered SUVs. GM has previously announced plans to make some of its future electric vehicles capable of driving themselves in robot taxi fleets. The company offered sneak peeks of three electric vehicle prototypes: a Buick brand sport utility vehicle, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM collaborated with Korean battery maker LG Chem to build the Bolt battery system. Company officials did not say what companies would supply batteries for the larger fleet of vehicles promised by 2023. Fuel-cell vehicles will also play a role in GM's future, the company said.

Cadillac Lyriq EV unveiled as brand's first electric vehicle

Your author has already seen it, back in March, and has had to wait until today to show you the new Cadillac Lyriq electric luxury crossover. We were excited about it then, we're still excited about it now, but we'll see if we can maintain that excitement for another two years. After some fanfare, a delay, a name explanation and a bit of teasing, Cadillac has finally taken the wraps off the Lyriq, and we like what we see. The bad news — weÂ’ll get it out of the way right now — is that the Cadillac Lyriq wonÂ’t go on sale until late 2022. Moving on, letÂ’s bask in the photos and video weÂ’ve long awaited, and dig into what we know about the first all-electric Cadillac. First, it will come in two drivetrain configurations: rear-wheel drive and performance all-wheel drive. ItÂ’ll use GMÂ’s new Ultium modular battery technology, giving it a driving range targeting north of 300 miles, plus a center of gravity about 3.9 inches lower than that of the similarly sized Cadillac XT5. It will be capable of "over" 150-kilowatt DC fast charging, with a Level 2 charging rate of up to 19 kW. Cadillac Lyriq View 8 Photos In terms of styling, the Lyriq is a substantial move forward both inside and out — and a lot of it has to do with lighting. On the outside, it gets vertical headlights, plus a bunch of little light-up elements in the grille, include a logo that is animated on startup. In fact, the face will light up as you approach, not unlike a dog seeing its best friend ready to play. We see some more nifty lighting signatures in back that carry on a similar theme with more vertical lights. Inside, the lighting situation gets even more interesting, with another light-up crest on the steering wheel, plus wood veneer over aluminum door panels, all backlit. As for its stance, the Lyriq has a long wheelbase, and rides on 22-inch wheels. At the back, we see a slick vented spoiler hanging over the raked rear glass. The side doors of the Lyriq automatically open with the touch of a button in door handle outlines that are flush with the body. Similarly, they close automatically, slowing down at the end to pull the doors fully shut. We wouldn't be surprised if this doesn't make it to production. Moving around the interior, the curved, 33-inch combination digital driver display and infotainment screen sprawls across the dash. It uses advanced LED technology, and is capable of displaying over a billion colors, according to Cadillac.
