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.

2019 Toyota Corolla vs. compact hatchbacks: How they compare

So you've read what we thought about the 2019 Toyota Corolla Hatchback. Oh, you didn't? Well, click to your left, we'll still be here. Just made some coffee, we're good for a while. Welcome back! Wasn't that riveting? The blue paint sure is bright, eh? Well, now you must be wondering how that new 2019 Corolla stacks up with all the other hatchbacks. And, despite long thinking that hatchbacks were doomed, there are actually quite a lot of them these days. So many, in fact, that we couldn't fit them all in our space-limited comparison chart. So, with apologies to the Hyundai Elantra GT, Kia Forte and the dead-man-walking Ford Focus, these were the cars we chose based on sales and competitiveness: the Honda Civic Hatchback, Mazda3 5-Door, Volkswagen Golf, Chevrolet Cruze and Subaru Impreza. We also included the outgoing Corolla iM for reference. If you think we've left something of interest out, you can always create your own comparison. Performance and fuel economy There is but one king here, and its name is Civic. While the sedan and coupe come with a naturally aspirated 2.0-liter 158-horsepower four-cylinder that's less potent than the Corolla's, the hatchback comes standard with the 1.5-liter turbo that aces the segment in terms of both acceleration and fuel economy. The Golf's acceleration should be comparable, but as you can see, it trails on fuel economy (still not bad, though). The new Corolla ends up being better than the rest with its new 168-hp four-cylinder paired to novel transmissions: a six-speed manual with rev-matched downshifting (!) and a CVT that mimics the actions of a 10-speed automatic. The Corolla does weigh more than everything else, though, so that could hamper its acceleration. Fuel economy data also wasn't announced, but Toyota indicated it would be a bit better than the old Corolla iM. Something akin to the 2.0-liter Mazda 3's numbers seems likely. As for the Mazda, its top two trim levels actually come standard with its bigger engine. In any event, despite its ample power, testing has often showed that the Civic is still the quicker car from 0 to 60 mph. And finally, let's not leave out the two on the end. The Subaru is the only car in the segment that offers all-wheel drive (the Focus RS and Golf R don't count), but is also the segment weakling now that the Corolla iM has been discontinued.

GM execs fired over fraudulent India emissions testing

General Motors hadn't had a recall in India since 1995. That changed when it was discovered that certain employees were playing tricks with local emissions testing in order to ensure passing grades for engines. More than ten GM Powertrain employees in India and the US have been let go over the ensuing emissions flap, including Sam Winegarden, VP of global engine engineering, a man who has been with the company since 1969, leading development of some marquee powerplants.
According to Automotive News, an internal investigation revealed that employees "violated testing procedures," sometimes swapping specially prepared low-emissions engines during testing regimes for the Chevrolet Tavera SUV equipped with the 2.0-liter and 2.5-liter engines. Employees were also manipulating weights in order to get vehicles placed into different emissions categories. The discovery has led to GM recall the 114,000 Taveras produced over an eight-year period and halting their production and sale.
The Economic Times of India reports that the issue is due to "a faulty component." GM has developed a solution to the issue, and once it is validated in testing and approved by the Indian authorities, the recalled vehicles will be fixed at dealers and production will resume.
