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.

Is this GM's next electric crossover?

GM made headlines this week when CEO Mary Barra presented the company's electrification and automation plans at the Barclays Global Automotive Conference in New York. "We are committed to a future electric vehicle portfolio that will be profitable," Barra said, which could be taken as a jab at Tesla. In the presentation ( PDF here), though, we see a new vehicle in a slide titled "Leveraging existing BEV platform to expand in near term." The vehicle, seen above, accompanied the captions "New CUV entries" and "two entries by 2020." Is this a sneak preview of an upcoming electric crossover from GM? The image seems too realistic and intentional to be a random placeholder. If this is, indeed, an upcoming battery-electric CUV based on the Bolt, the question remains: Will it be a Chevy or a Buick? It has no visible badging, but it shares DNA from both brands. As Inside EVs points out, though, it does bear a resemblance to the Chevrolet FNR-X concept unveiled in Shanghai earlier this year. With two CUVs on the way, it's not unthinkable that there could be a version for each brand. In addition to this slide, the presentation includes plans for an "All new multi-brand, multi-segment platform" launching in 2021. The all-new modular battery system will cost less than $100 per kWh, providing higher energy density and faster charging. The platform will host at least nine different vehicles, including a compact crossover, seven-seat luxury SUV and a large commercial van. GM has said it will launch 20 new EVs by 2023, and that it targets 1 million EV sales per year by 2026. Many of those sales will be in China. Related Video:

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
