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.

Why the 2015 Detroit Auto Show will be the best since The Crisis

The Detroit Auto Show clearly has its swagger back, and the 2015 edition will be a veritable feast for the enthusiast senses. We're talking serious performance, and it will be exhibited in a variety of forms. Sports cars. Supercars. Muscle-bound luxury cars. They're all set for splashy debuts in January in the Motor City. It's another signpost that companies have recovered from the global economic crisis that gripped the industry from 2008-09. For a while, automakers played it safe at Detroit and other shows. Environmentally friendly cars were important, especially for General Motors and Chrysler that were living on loans from Uncle Sam. Ford, Toyota and other companies generally focused on their best-selling or core models. With a few notable exceptions, recent auto shows have been a bit more buttoned-down than in the past. Boring probably isn't the right word, but austerity has been reality. That's changing. Car companies are making money. Sales are up. Aside from the many nagging recalls – and they are notable – the industry now has the time and energy to make performance cars a priority. That will be offered in hard evidence in Detroit. A year from now when we look back at this auto show, we'll sum it up with one word: Horsepower. But make no mistake, this isn't frivolous. Sports and luxury cars are expensive. They're profitable. They boost images and highlight strengths. With that in mind, here are five significant performance-oriented reveals to watch for when the show kicks off in less than two weeks. 2016 Acura NSX Acura's reborn NSX is a strong bet to earn plenty of votes for our Editors' Choice awards. It's one of the most anticipated – and strung-out – reveals of the year. Think back: we actually saw an NSX concept at the 2012 Detroit show, and Acura has spent the last three years teasing the car in a variety of ways. The slow burn, however, means we know a lot about the NSX. It's will use a mid-mounted twin-turbo hybrid powertrain and run with all-wheel drive. It will also wear an innovative zirconium e-coat paint, a new paint process that Honda says is more environmentally friendly. Honda has also said it will build the new NSX in Ohio, where a large part of the car's development work has been done. The original NSX was produced from 1990-2005 and helped establish Acura's performance credentials in the United States. It was a landmark car and a shot across the bow of Ferrari, Lamborghini and others.

Bosch builds an infotainment system that just might not suck

As far as we've come with in-car infotainment and interfaces over the past decade or so, we still have a long way to go — as most current systems show. Whether it's high-end brands like Mercedes-Benz with its kludgy COMAND system, which we hope will be replaced with the MBUX platform revealed at CES, or more mainstream vehicles like Hondas (with their frustrating, knobless Display Audio interface), getting the kind of content and ease of use in the car that we're used to having on other connected devices is far too complex and sometimes costly. While Apple and Google have tried to ride to the rescue with CarPlay and Android Auto, respectively, they're limited solutions. No automaker or tech supplier has been able to deliver an easy, economical, flexible and non-distracting infotainment solution. But Bosch could be closing in on this elusive goal, given the digital cockpit concept demo I recently received at CES. Displayed in a Cadillac Escalade, the concept featured five interconnected color screens: one in the instrument cluster, two in the center console, and two more in the front-seat headrest for second-row passengers. The digital cockpit concept demo had cool features such as haptic-feedback touch-screen controls that created an edge-like feeling similar to a physical button, facial recognition to confirm driver credentials, and the intelligence to know the location of a phone in the car to lock it out to keep the driver from texting. The most significant aspect of the Bosch digital cockpit concept wasn't visible — but shows the company's vision for a future of seamless, convenient, cost-effective and safe in-car infotainment. It's powered by a single electronic control unit (ECU) that can simultaneously run multiple operating systems and also separates vehicle and infotainment controls for critical safety and cybersecurity reasons. Most modern cars can have as many as 100 separate ECUs, Philip Ventimiglia, product manager for Bosch Car Multimedia North America, explained at CES, and several just for infotainment functions. "The goal is to reduce that to about 10 so that we can save cost throughout the vehicle and enable new technologies," he added. "OEMs want to put more technology into cars, but it costs money," Ventimiglia said.
