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.

How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.

Cadillac will kill the plug-in ELR

Johan de Nysschen, president of General Motors' Cadillac division, says Caddy's ELR extended-range plug-in won't have any future generations, Automotive News (subs. req.) says. The publication previously reported that the car would be around for another couple of years, but even that's questionable, and the model could be yanked even sooner. Cadillac spokesman David Caldwell confirmed that there won't be a second-generation ELR. "Subsequent generations of the car will not be developed," he wrote in an e-mail to Autoblog. "It's available currently as a 2016 model, and there's no change to that status." The model debuted in late 2013 and used a version of the powertrain in the Chevrolet Volt. The main problem, of course, was that the car had a $76,000 price tag that proved too much for most automobile buyers to stomach. Last year, GM sold 1,024 ELRs, down 22 percent from 2014's totals. By comparison, the Chevy Volt moved more than 15,000 units, and that itself was still down 18 percent from year-earlier figures. The merciful end to the ELR shouldn't be much of a surprise, as Cadillac Chief Marketing Officer Uwe Ellinghaus went on the record in December of essentially calling the model a dud. It's a far cry from the excitement, though, that the concept model of what was then called the Converj was unveiled to the public at the Detroit Auto Show in 2009. For those feeling misty-eyed or nostalgic, though, check here for Autoblog's First Drive impressions of the extended-range plug-in.
