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.

Cadillac clears camo off the XT3 revealing grille, lighting details

Up until now, every Cadillac XT3 we've seen has been buried under covers and vinyl wraps, but one of our spy photographers recently captured a group of them with significantly less camouflage. As a result, we finally get a relatively clear picture of what the car will look like. The nose blends the look of current Cadillacs with cues from last year's Escala concept. The headlights still appear to stretch up into the top of the fenders like its production brethren, but they don't descend as far down the front fascia, a hint of Escala influence. The grille also features more of egg-crate mesh like that Cadillac concept. In profile, we can see evidence of the XT3's smaller size compared with the XT5, mainly in the lack of any glass area behind the rear door. Other evidence of the smaller size is that our spy photographer reports the cars were being tested alongside the BMW X3 and Mercedes-Benz GLC-Class. The profile also shows that the XT3 will have a hard-edged rear end with a rakish hatch. At the back, there isn't a whole lot to report, but the taillights look like they'll be interesting. There appears to be a horizontal element in the middle of the hatch similar to what we've seen on the Escala and the refreshed XTS. We can also see some lights up on the C-pillar, which indicates that the XT3 will also have tall vertical elements up those pillars like on the Escalade. We expect the XT3 to show up late in 2018. It will likely be powered by a turbocharged four-cylinder of some sort, and because it will probably be based on an existing GM crossover or sedan platform, it will probably have front-wheel drive and/or a front-drive based all-wheel-drive system.

Junkyard Gem: 1998 Cadillac Catera

A decade or so after Ford tried to swipe some US-market sales from European luxury marques by selling the German-built Ford Scorpio with Merkur badging, General Motors opted to sell the German-built Opel Omega luxury sedan as a Cadillac. The Catera was a reasonably nimble rear-wheel-drive sedan with a 200-horse DOHC V6 engine, and its badge-engineered nature made it a much less costly gamble than, say, the Cadillac Allante, which had its bodies built in Italy and flown to Michigan for assembly. Unfortunately, it had no manual transmission option, and Americans who remembered the miserable US-market Opels of the 1970s were put off by the Catera's Opelness. Its $29,995 list price was quite a bit cheaper than that of the (slightly less powerful) $39,800 BMW 528i and a bit less than the (slightly more powerful) $33,585 Acura 3.2 TL's cost, but the Catera didn't sell in large numbers. This one made it to a respectable mileage figure, and the nice interior shows that it was well-cared-for during its 18 years on the road. The ads for the Catera featured a cartoon duck named Ziggy. Fast, fun, fiendishly flexible! By 2000, Cadillac had ditched the duck and was touting the Catera's value. Related Video:
