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 tells owners not to use SUV wipers due to fire risk

General Motors is recalling 31,685 examples of the 2016 Buick Enclave, Chevrolet Traverse, and GMC Acadia because a short circuit in the windshield wiper motor can potentially lead to a fire. Due to the danger, the company is asking owners not to use the wipers until the problem is fixed, according to The Detroit Free Press citing the Associated Press. A manufacturing defect in the wiper motor cover means that the electrical terminals can come into contact and cause a short. The part could "melt, smoke, or catch fire," according to a statement from GM. The company will get them fixed immediately, and dealers will replace the cover. If there's bad weather at the time the owner specifies to get the recall work completed, the automaker will come pick up the crossovers. Depending on parts availability, the automaker will supply a rental car for customers, as well. The issue was discovered at the factory. According to the company's statement, only 6,405 actually made it to customers, and they were notified immediately by overnight letter. The rest were in dealer stock. The affected crossovers carry build dates between August 18, 2015 and September 24, 2015. Of those, there are 29,295 in the US and 1,073 in Canada. GM Statement: General Motors has told the National Highway Traffic Safety Administration that it will recall approximately 29,295 2016 model year Chevrolet Traverse, Buick Enclave and GMC Acadia SUVs in the U.S. because the front windshield wiper motor may overheat when in use because of a manufacturing defect. In some cases, the front windshield wiper motor cover may melt, smoke or catch fire. The approximately 6,405 customers who have taken delivery of these vehicles were notified by overnight letter and are urged to contact a GM dealer as soon as possible to arrange a service appointment. These customers should not use the front windshield wipers until they have been repaired. If weather conditions prevent driving the vehicle without using the windshield wipers, GM will arrange to pick up the vehicle for servicing. If repair parts are unavailable, GM will provide a rental car at no cost until parts become available. The total population, including Canada, Mexico and exports, is approximately 31,685. About 25,280 of these vehicles are in dealer stock and will not be sold until repairs are made.

Best Convertibles for 2022

The past decade has not been kind to the drop-top enthusiast. No matter which dealer you walk into, convertible models have been biting the dust left and right. Nissan Z? Audi TT? Buick Cascada? Volkswagen Eos? All gone. Remember the humble Chrysler Sebring/200? Well, you do now. Fortunately, though, the news isn't all bad. There are still plenty of options out there for those who absolutely must have a convertible. Whether you need something to haul behind your retirement cruiser, a performance car that can go toe-to-toe with the best in the world or just something that allows you to sling the roof back after a long day of on-location business meetings before catching the flight back to your everyday hustle and bustle, there's at least one cabriolet out there to suit your needs. Here are our picks and starting prices for the top convertibles in several categories for 2022.  For the frugal open-top lover: 2022 Mini Convertible ($34,650) Let's face it; gas ain't cheap. But open-top motoring doesn't need to be a wallet killer. The Mini is cheap (at least by 2022 standards) and an absolute joy to drive, so there's really no downside here ... except for the roof. Get it?    For the hardtop lover: 2022 Mazda MX-5 RF ($37,260) / 2022 Chevrolet Corvette Convertible ($69,695) The number of hardtop convertibles has seriously dwindled due to weight concerns and the fact that fabric roofs have gotten so quiet, but there are still some options for those who prefer a more coupe-like look with the roof up. Our picks here are the delightfully Targa-like MX-5 Miata RF and literally any Corvette Stingray — even the hardtop has a removable roof!    For long road trips: 2022 Ford Mustang Convertible ($34,100) The first image that comes to mind for many who are told to visualize an American convertible is the classic Ford Mustang. It's not the only drop-top pony car out there, but thanks to the Camaro's tiny trunk, it's much harder to see the USA in a Chevrolet when a drop-top enters the equation. The Mustang has much more cargo space and a much larger opening, which is likely the difference between keeping your bags under lock and key or leaving them exposed in the back seat.    For towing behind an RV: 2022 Jeep Wrangler ($31,590) While many small runabouts make sense for towing behind a motor home (or nestled up inside a fancier one), the Wrangler has a serious advantage when it comes to RVing: it can easily be flat-towed.
