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, Ford, Toyota, Stellantis CEOs want EV tax credit cap lifted

For just over a decade now, the U.S. has had a federal tax credit worth up to $7,500 for buyers of electric cars and plug-in hybrids. The catch has been that, once 200,000 of them were claimed for a manufacturer, that credit would be phased out. Now, automakers are asking for this cap to be lifted across the board, specifically General Motors, Ford, Toyota and Stellantis. The request comes in the form of a joint letter to Congress (which you can read here), signed by the CEOs of each company. And the ask really is as simple as that. The automakers would like the cap lifted for all EV manufacturers, and instead have a sunset date for the tax credit put in place. Broadly speaking, they want it lifted because of concerns about rising costs from materials and supply chain issues, which can lead to higher prices and could discourage buyers from getting an EV. It would also put automakers back on an even playing field. GM reached its tax credit cap a few years ago, meaning that none of its EVs are eligible for the tax credit. So while it reaped the benefits early on, it now has something of a disadvantage to competitors with credits remaining, such as those that signed on to this letter. GM wouldn't be the only beneficiary. Tesla ran out of credits years ago, too. Nissan still has credits, but likely not for much longer, as InsideEVs reports around 190,000 Leafs have been sold in the U.S. as of April. So it will probably face a phase-out soon, just as the anticipated, and more expensive, Ariya is heading to market. Making this change would also seem like a good choice for continuing to stimulate EV sales, if that's what the government is looking to do. While EVs are now reaching parity in practicality and performance with gas-powered cars, having an additional financial incentive will surely keep them looking more attractive. And automakers can push EVs without fear of running out of credits early. Certainly some sorts of changes to the EV tax credit are likely. There are bills in the works focusing on cap changes as well as the amount of money available, and which vehicles are eligible. Credits up to $12,500 have been proposed, plus possible credits for used EV sales and restricting some credits to vehicles of certain price brackets. Of course, any changes will require some cooperation in a deeply divided Congress. Related Video: Government/Legal Green Chevrolet Chrysler Ford Toyota Electric EV tax credit
