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 trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.

Chevy previews 2016 Malibu ahead of New York debut

With everything going on in Geneva this week, it would be all-too easy to forget that there's still stuff going on back home in America. And the upcoming new Chevy Malibu is a prime example. Chevrolet has announced that it is bringing an all-new Malibu to the New York Auto Show next month, teasing us with this preview image and a few enticing details. For starters, when we say it's all new, this time we mean it's all new. The next-generation Malibu has been built on a new platform that uses more high-strength steel to cut 300 pounds off the curb weight compared to the outgoing model. It's also got a wheelbase that's almost four inches longer, with shorter overhangs front and rear and a roofline that tapers stylishly and more gradually towards the tail. We'll have to wait a little longer – but not too much longer – to find out more, but in the meantime you can read what Chevy's telling us so far in the press release below. Born Again: Next-Gen Chevrolet Malibu Announced Larger, lighter and more efficient Malibu to be unveiled at New York Auto Show 2015-03-04 DETROIT – Designed to deliver more efficiency, connectivity and advanced safety features than ever, the next-generation 2016 Chevrolet Malibu will make its public debut at the New York International Auto Show this April. Using a blank slate approach, Chevrolet designers benefited from an entirely new architecture, which for Malibu includes a wheelbase nearly four inches longer than the outgoing model. That, in turn, provides increased rear legroom and interior space. Due to a higher-strength steel structure, the new Malibu is also expected to be 300 pounds lighter than the current model, which benefits the sedan's fuel economy and handling. "Malibu's gorgeous styling is the result of a masterful understanding of proportions," said Ed Welburn, General Motors' vice president of Global Design. "The roofline has been stretched rearward giving a more sleek profile, while the front wheels have moved forward and front and rear overhangs have been reduced. Along with the sculpted body side, these cues help Malibu appear more dynamic and sophisticated." More details about the 2016 Chevrolet Malibu will be shared each week leading up to the vehicle's global debut. The 2016 Malibu is expected to go on sale by the end of 2015. Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 115 countries and selling around 4.8 million cars and trucks a year.
