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.

'84 MotorWeek Cherokee, Bronco and Blazer comparison indulges your SUV nostalgia

These days, truck-based, full-frame SUVs are somewhat of a rarity on the auto landscape due to the rapid rise in popularity of easier-driving, car-based crossovers. Although, without the gradually building popularity of these chunky, high-riding vehicles decades ago, it's unlikely that America's roads would be filled with so many CUVs today. In its latest dig into the archives, MotorWeek has found a 1984 comparison test of a trio of these early Sport Utility Wagons, as long-time host John Davis called them, that helped get acceptance of this segment going. This is a red, white and blue test of the SUVs from American automakers at the time and pits the Chevrolet Blazer, Ford Bronco and Jeep Cherokee (specifically in Wagoneer guise) against each other. Driving manners and interior usability are considered in the evaluation, but Motorweek actually takes these vehicles off road, too. Among the bigger revelations is the improvement in on-road ability in the past 30 years. While specific 0-60 times aren't given, all three models take around 10 seconds just to get to around 50 miles per hour in the 500-feet on-ramp acceleration test. Check out this clip to see just how far this segment has progressed in the past three decades or just get a blast of nostalgia from these now vintage models.

Chevy Bolt-based prototype may be a Buick EV for China

Late last spring, we got a look at a GM prototype that was clearly based on the Chevy Bolt EV, but with updated styling. It seemed like it could be a more crossover-styled Bolt, given the recently trademarked name of EUV. Now we get another look at the prototype, but the bodywork seems less suggestive of a Chevy, and more of a Buick. This vehicle definitely still appears to be based on the Bolt, rather than on another small GM platform. In the photos of it next to the current model, the size, wheelbase and profile are extremely similar. There are differences, though. The nose isn't as sloped or as rounded, and the rear window kicks up a little earlier. The biggest changes are in the front and rear fascias, and it's here that we see hints of Buick. There are prominent air inlets on each side of the front bumper that give the car a more aggressive look. The headlights still have a fairly rounded, organic look, but with little extensions like fangs underneath. The styled running-light section, rounded shape and the smoked lenses seem very Buick-like. The grille features a large badge that doesn't fit the shape of a bow-tie, and is more that of a round logo like Buick's. Around at the back, the full-width taillights stand out, and in the middle there is obviously a round badge, again like a Buick. The wide taillights would also be a natural evolution of Buick's current light design language that uses somewhat wide and thin lights. The rear bumper has been redesigned with new lower taillights. Now that we've established that this seems very much like a Buick, we don't think we'll see this particular version offered here with the badge. This is more likely a Buick version of the Bolt for the Chinese market, where the brand is associated with luxury and has been the spearhead for GM's electric and hybrid models. In fact, the Chevy Volt hybrid was sold there as the Buick Velite 5, which was part of a family of a electrified Velite models. This would probably also carry a Velite badge as well. While we might not see this specific Buick variant, we probably will see it offered as a Chevy in some form. With its more aggressive, crossover shape, it could be the rumored EUV model. Or it could be just a refresh of the current Bolt, since the model has been largely unchanged since its introduction for the 2017 model year. And extrapolating from this prototype, we can see how the headlights could be tweaked to tie into those air scoops as on the Suburban and Silverado.
