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.

2017 GMC Acadia starts at $29,995

The 2017 GMC Acadia has a lower price in addition to its smaller size and 700-pound weight loss. The latest model starts at $29,995 (including $925 destination) when it arrives at dealers this spring, which is $1,905 less than last year's base version. That low price is just for the front-wheel-drive only SL trim, but there are savings throughout the 2017 lineup. The least expensive all-wheel drive version comes on the SLE model for $35,375, versus $37,100 last year (after $925 destination). The top-spec all-wheel drive Denali now costs $47,845, compared to $50,815 for the 2016 version. You can check out the MSRP for each trim in the release below. The new All Terrain model costs $40,040 and gets a more sophisticated all-wheel drive system with an active twin clutch. GMC claims the layout improves performance in wet, snowy and icy conditions. However, the trim is only available in five-passenger configuration, and storage bins in the floor replace the third-row seat. The 2017 Acadia price is also competitive with some challengers in the segment. For example, a base 2016 Honda Pilot is more expensive at $31,045 (after $900 destination), and the top Elite is $47,470, which is barely cheaper than the Denali. A base 2016 Ford Explorer is more costly at $31,995 (after $945 destination), and the Platinum for $53,915 is several thousand more than a Denali. The latest Acadia offers customers a bounty of tech and efficient powertrains. The IntelliLink infotainment system has support for Apple CarPlay and Android Auto, and there're available safety systems like front pedestrian braking and a surround view camera. Most models come with a 2.5-liter four-cylinder, which GMC estimates gets 22 miles per gallon city and 28 mpg highway with front-wheel drive. A 310-horsepower 3.6-liter V6 offers an estimated 25 mpg highway for front-wheel drive models. Both powertrains use a six-speed automatic.

2018 GMC Sierra 2500HD All Mountain concept: Nothing stops it in its tracks

Winter may not be the best time for sports cars, but snow and ice can still provide a ton of fun in the right vehicle. The Porsche Macan GTS I had back in January was a riot in the snow, and it was wearing nothing more than a good set of winter tires. What you really need to conquer the frozen north is tracks. These replace wheels with the same sort of equipment that helps tanks and snowmobiles roll over damn near everything in their paths. That's what makes the 2018 GMC Sierra 2500HD All Mountain concept so awesome. That and the 910 pound-feet of torque from the 6.6-liter Duramax turbo diesel V8. The All Mountain concept is set to debut this week in Veil, Colorado, home to ski slopes, log cabins and nearly year-round snow pack. The truck is based off a standard GMC Sierra 2500HD. The turbo-diesel V8 makes 445 horsepower in addition to the mountain of torque. Power is sent to all four corners through an Allison 1000 six-speed automatic. The new treads come courtesy of Mattracks. The 150 Series tracks aren't cheap — well into five figures with installation — but they give you a nice 16-inch surface at each corner. Other changes and add-ons include graphics on the bodywork, a RIGID E-Series 30-inch light bar, LEDs on the wheel well and underbody, Thule snowboard racks, a roll-up tonneau cover and a new speaker system from Kicker. The truck will stay on display in Veil all winter, though a similar concept will be making its way to various auto shows, starting with Los Angeles next week.
