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.

GMC Hummer EV's taillights cost thousands to replace

The GMC Hummer EV pickup hasn’t stopped raising eyebrows since GM pulled back the curtain on the behemoth in Spring 2021. ItÂ’s huge, not all that efficient, and unbelievably expensive, but now weÂ’re learning how much replacement parts cost for the new EV. The Drive dug up a post from the Hummer EV Facebook page that claimed a taillight replacement for the vehicle costs thousands to replace. General Motors confirmed pricing to the publication, quoting a one-side replacement cost of $3,045.48. That adds up to more than $6,000 to replace both, so we hope your insurance is solid if you own one. Why would a taillight housing cost that much? Part of the cost comes from the fact that GM couldnÂ’t parts-share its way through the design of a $100,000 flagship electric SUV, but most of the price comes from the complexity of the lights. The Hummer offers elaborate lighting sequences that require microchips and other components, all of which cost money. ThereÂ’s also the fact that the Hummer EV is too new for General Motors to take advantage of its usual economies of scale in mass-produced vehicles. General Motors recalled the Hummer EV earlier this year for issues with the taillights. Though the problem was software-related, GM had to replace the entire light units because the software controlling them was actually embedded in the lights. ItÂ’s true that there are very few vehicles that are tall and large enough to impact the HummerÂ’s taillights, but we hope the owners of those vehicles never have to file an insurance claim to replace one.

New Toyota Tacoma, Ranger, Colorado/Canyon fight for midsize truck dominance

Sam Wedll has been driving his Toyota Tacoma pickup on the rugged roads of Northern California for seven trouble-free years, racking up almost 100,000 miles, so he’s interested in the redesigned version of the truck coming later this year. He paid $34,000 for his truck in 2016, loading it with plenty of options. HeÂ’s eyeing the new gas-electric hybrid Toyota Motor Corp. is going to offer, but Wedll, who does his own repairs, isnÂ’t interested in paying luxury prices. “The hybrid is pretty interesting to me because I like the idea of the fuel efficiency,” says Wedll, 47, a casino operations manager in Blue Lake, California. “IÂ’m just trying to save some costs wherever possible.” The Tacoma, known as the Taco to its legions of loyalists, is the leader of the pack in midsize pickups, one of the fastest-growing auto markets of the past decade. With outdoorsy weekend warriors and do-it-yourselfers looking for a truck that could fit in their garage, sales of midsize pickups more than doubled from 2010 to 2020. General Motors Co. and Ford Motor Co., which abandoned the market segment when sales slowed early this century, returned with new trucks to take on the Tacoma, which has dominated the medium truck market for almost two decades. Although it's easy to predict that the most lushly appointed versions of the new Taco could approach $50,000 (prices wonÂ’t be announced until later this year), Toyota insists it isnÂ’t backing away from budget buyers even as it rolls out fancier trucks. The current Tacoma starts at $28,030, and the company says affordability is critical to its success. In fact, Toyota will continue to offer the Taco with an old-school stick shift. The Tacoma controls 42% of the midsize truck market and outsells FordÂ’s offering 4 to 1. ThatÂ’s a role reversal from the full-size pickup market, where FordÂ’s F-Series has ruled the road for 46 years. Tacoma sales in the U.S. surpassed 237,000 last year, more than twice the number of GMÂ’s No. 2-ranked Chevrolet Colorado, according to consultant LMC Automotive. But as growth in the overall segment slows, the midsize market is developing into more of a turf war, with manufacturers vying for the sweetest highest-margin spots. “This segment is likely past its prime growth spurt,” says Jeff Schuster, president of the Americas for LMC Automotive.
