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.

Here are a few of our automotive guilty pleasures

It goes without saying, but I'll say it anyway. The world is full of cars, and just about as many of them are bad as are good. It's pretty easy to pick which fall into each category after giving them a thorough walkaround and, more important, driving them. But every once in a while, an automobile straddles the line somehow between good and bad — it may be hideously overpriced and therefore a marketplace failure, it may be stupid quick in a straight line but handles like a drunken noodle, or it may have an interior that looks like it was made of a mess of injection-molded Legos. Heck, maybe all three. Yet there's something special about some bad cars that actually makes them likable. The idea for this list came to me while I was browsing classified ads for cars within a few hundred miles of my house. I ran across a few oddballs and shared them with the rest of the team in our online chat room. It turns out several of us have a few automotive guilty pleasures that we're willing to admit to. We'll call a few of 'em out here. Feel free to share some of your own in the comments below. Dodge Neon SRT4 and Caliber SRT4: The Neon was a passably good and plucky little city car when it debuted for the 1995 model year. The Caliber, which replaced the aging Neon and sought to replace its friendly marketing campaign with something more sinister, was panned from the very outset for its cheap interior furnishings, but at least offered some decent utility with its hatchback shape. What the two little front-wheel-drive Dodge models have in common are their rip-roarin' SRT variants, each powered by turbocharged 2.4-liter four-cylinder engines. Known for their propensity to light up their front tires under hard acceleration, the duo were legitimately quick and fun to drive with a fantastic turbo whoosh that called to mind the early days of turbo technology. — Consumer Editor Jeremy Korzeniewski  Chevrolet HHR SS: Chevy's HHR SS came out early in my automotive journalism career, and I have fond memories of the press launch (and having dinner with Bob Lutz) that included plenty of tire-smoking hard launches and demonstrations of the manual transmission's no-lift shift feature. The 260-horsepower turbocharged four-cylinder was and still is a spunky little engine that makes the retro-inspired HHR a fun little hot rod that works quite well as a fun little daily driver.

2020 Cadillac XT6 Sport First Drive Review | An unexpectedly strong performer

Cadillac is in an unenviable position right now. Over the past few years, it developed some excellent driving sedans just in time for the world to demand nothing but crossovers. Now it’s working fast to get more crossovers on the market besides the XT5. Its latest is the 2020 Cadillac XT6, a large three-row luxury crossover designed to slide under the enormous Escalade and provide less truck-like driving characteristics. And while it has an underwhelming wrapper, itÂ’s actually a refined, capable and spacious luxury crossover. Still, it must be emphasized that the Cadillac XT6 does not make a strong first impression. The Escalade is brash, bold and above all, big. That's exactly what's been historically expected from Cadillac, but the XT6 just looks like any three-row crossover with some creased lights and lines that help make it look like a Cadillac. ItÂ’s not ugly, but it's not memorable, either. The interior is a mixed bag. The materials are impressive, with interior panels covered in leather and suede in a loaded Premium Luxury version we drove (we haven't had a chance to see a base version). The other trim level, the Sport, gets real carbon fiber trim thatÂ’s made more interesting with copper wires woven into the material for a metallic glint. ThereÂ’s real metal trim throughout, too, from the shift paddles to the nicely weighted infotainment and volume knobs. Unfortunately, the actual dash design looks uninspired and even a little cheap. This is something that weÂ’ve noticed on many GM vehicles, and what seems to be the culprit is that every panel is oddly chunky and blunt. There are no crisp or sharp edges, no thin details, no "wow" moments. The seats arenÂ’t particularly impressive either, as theyÂ’re flat and not very supportive. More lumbar and bolstering would help. The interior is at least spacious, with loads of head, leg and shoulder room in the first two rows. The third-row seat is even usable by adults, at least for short trips since head- and legroom are tight and the seat itself is low. It's similar to what you'd find in the more expensive BMW X7, but less than a Buick Enclave or most non-luxury three-row crossovers. Access to the third row is quite good thanks to the far-sliding second row, and it folds away into the cargo floor at the push of a button at either rear door. There are also USB outlets for every seating position, another thoughtful touch. Once the Cadillac XT6 is on the road, it has some impressive aspects.
