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.

OnStar RemoteLink mobile app coming standard on all new GM vehicles

As an evolution and improvement of its OnStar technology, General Motors has announced that it will be expanding the RemoteLink Mobile App on most 2014 model year Chevrolet, Buick, GMC and Cadillac vehicles. The new, aptly named RemoteLink Key Fob Services will allow users to remotely operate all of the same systems as the car's key fob, including locking and unlocking the doors and remote starting (on vehicles equipped with a factory remote starter) using a smartphone.
These Key Fob Services will be free for five years - starting from the vehicle's delivery date - but the full suite of RemoteLink features will continue to be offered only with a subscription (trial or paid). These premium features include contacting a live adviser, getting turn-by-turn directions and remotely monitoring the vehicle's diagnostic systems.

2023 GMC Yukon Denali Ultimate comes with more style, most everything else

First introduced on the Sierra line, the even more luxurious Denali Ultimate trim is coming to the 2023 GMC Yukon. It includes nearly every available feature for the regular Denali as standard, plus some unique design features. The Denali Ultimate is distinguished by its dark chrome grille and badging, features that cannot be added to any other Yukon model. It also gets the largest wheels yet for the Yukon: 22-inchers with painted, machined and polished sections. The interior is more impressive. Most of the surfaces are covered in leather, real wood and aluminum trim. The seat backs and the wood trim have topographical maps of Mount Denali. Metal badging is even added to the seat backs with the special trim level's name. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. As for features, the Denali Ultimate comes with basically everything that's standard as well as what's usually optional on the regular Denali including magnetic shocks, huge screens, an 18-speaker sound system and massaging seats, among others. So this is one of the rare times where it actually is easier to list what's either an additional feature or just a preference. Naturally you get a choice of colors, and the trim level can be added to either the shorter Yukon or the longer Yukon XL. The standard engine is the gas-powered 6.2-liter V8 with 420 horsepower and 460 pound-feet of torque. The 3.0-liter turbodiesel straight-six is an option with 277 horsepower and the same amount of torque. Both are coupled to a 10-speed automatic and four-wheel drive. Super Cruise with towing and automatic lane change capabilities is another option, a rear-seat entertainment system and a towing package. And that's it. Pricing hasn't been announced, but it's pretty clear this will be the most expensive Yukon trim. The final numbers will be coming this June. Deliveries begin this fall.
