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.

AWD turbodiesel Equinox, Terrain dropped for 2020

Citing low demand, General Motors is dropping the AWD diesel options off the Chevrolet Equinox and GMC Terrain roster. Chevrolet spokesman Kevin Kelly confirmed to CarsDirect that for 2020, the diesel versions of these SUVs will only be offered with front-wheel-drive. CarsDirect notes that with the AWD diesel Equinox and Terrain gone, the only AWD diesel option in this class is the Mazda CX-5 Skyactiv diesel, which is significantly more expensive: As the AWD diesel CX-5 is only available in a fully loaded Signature specification, the $42,045 price tag is almost $10k heftier than the cheapest comparable Equinox, the AWD 1.6-liter diesel LT which starts from $32,495. The 2019 GMC Terrain AWD SLE costs $34,795 in comparison, which works out to being around $7,200 cheaper than the Mazda. The higher trim levels for the Equinox and Terrain are Premier and SLT, respectively. Some reasoning behind the AWD diesel GM SUV's low uptake is their own price difference to base FWD gasoline models: you can get a 1.5-liter Equinox for less than §25,000 listed. While the 2.2-liter Mazda has plenty more power at 168 hp and 290 lb-ft, compared to 137hp and 240 lb-ft in the 1.6-liter GM SUVs, the Equinox and Terrain are notably more frugal – they are rated 32mpg combined, while the Mazda can manage 28 mpg. With better fuel economy and a significantly lower list price, the General Motors twins are at least more wallet-friendly when it comes to numbers, and as the vehicles will cease to be built in that configuration there's likely to be some cash on the hood on ones in stock.

How the Ram Multifunction Tailgate compares to Ford, GMC, Honda

Ram just announced its Multifunction Tailgate — a descriptive if not very creative name. It's an asymmetrical barn-door arrangement, which can both fold down like a conventional tailgate or swing open like a gate. There's a new bed step, but unlike Ford or GM, the step isn't part of the tailgate itself. Rather, it kicks out from under the bumper (as opposed to out from under the driver's side of the rear bumper in its previous incarnation). So let's just focus on the tailgate functionality. A video of the Ram Multifunction Tailgate in action is above. For one, either of the swinging tailgate sections can be opened independently. They open to a full 88 degrees. In conventional flip-down mode, the tailgate works just like a normal one, too, with a 2,000-pound rating. The bottom line is that while it gives a variety of types of access to the load area, it doesn't "do" anything else. It's a $995 option on any Ram 1500. Its closest analogue is the Honda Ridgeline, which works basically the same way, but on that truck the tailgate swings as one piece. And the Honda's load rating isn't as hefty as the Ram's tailgate: 300 pounds. As Honda says, that's sufficient to hold the weight of the part of an ATV hanging out of the bed, or something similar, but it's a lighter-duty unit (and a lighter-duty truck) than the Ram's overall. Let's also get Ford's one-trick tailgate out of the way before comparing to the more analogous, and complicated, GM MultiPro. A bit of trivia: Ford's optional Tailgate Step is actually designed and supplied by Multimatic, better known as the outfit that builds the Ford GT and produces the DSSV spool-valve shocks. This step has been available for years. It pulls out of the top edge of the tailgate when the tailgate is lowered, deploying a single step. A separate handle pulls out from beside the step and flips up, giving a handhold. While it was initially (and infamously) mocked by competitors, with load floor heights as high as they are it's better than toting around a stepstool. It's currently a $375 standalone option. Now we get to the GMC MultiPro tailgate, the most complicated and multi-functioned around. It's essentially a tailgate within a tailgate, with a fold-out stopper that deploys from the inner tailgate. This gives it several functions depending on the position of all the parts. It can still be used like a normal tailgate, dropping down at the push of a button or using the key fob.
