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 CT6 V-Sport wants to take prisoners with 550-hp 4.2L TT V8

With the refresh of the Cadillac CT6 for 2019, Cadillac welcomes the first CT6 V-Sport as well as a new trim strategy. The changes at the front for the CT6 lineup don't appear substantial viewed head-on, one needs a side view to appreciate the greater three-dimensionality. Thinner headlights and a thinner bumper above a slightly larger lower front intake emphasize the mesh grille, and the vertical LED DRLs make more dramatic statements thanks to those narrower headlights. By angling the main units back toward the rear of the sedan, the CT6 now has a certified, sculpted snout. The rework appears to add substantial overhang, but overall length only increases by a tenth of an inch, to 204.1 inches. What's under the V-Sport's probing hood is just as interesting as the redesign and the sporting thrust: A clean-sheet design of a 4.2-liter DOHC twin-turbo V8. In the V-Sport, the engine produces 550 horsepower and a Bentley-esque 627 pound-feet of torque. As an optional engine elsewhere in the CT6 range, the same engine produces 500 hp and 553 lb-ft. The displacement, specs, plus the fact that "each engine will be hand-built at the Performance Build Center in Bowling Green, Kentucky" indicate this was one of the rumored powerplants for the mid-engine Corvette. The coming sports car was tipped to get a 4.2-liter and 5.5-liter DOHC twin-turbo V8. Based on the position of the turbos in this engine vs. their positions in the previous CAD drawings, we assume the drawings represented the 5.5-liter. (Note: Cadillac said Corvette will not get the new 4.2-liter twin-turbo engine.) The 4.2-liter item features an aluminum block, heads, and pistons, direct injection with a 9.8:1 compression ratio, cylinder deactivation, cylinder oil jets, and a variable-pressure oil system. The twin-scroll turbochargers capable of 20 pounds of boost sit in the 90-degree vee, working alongside twin water-to-air intercoolers, twin throttle bodies, and twin electric wastegates. Cadillac says 90 percent of torque arrives at 2,000 rpm and loiters through 5,200 rpm. Power gets sent through GM's 10L90 ten-speed automatic transmission and on to the standard all-wheel-drive system. Cadillac didn't list 0-to-60-mph times in its press release, but engineers have track-worthy alacrity in mind for the CT6 V-Sport.

Woman thwarts car thieves by jumping on hood

When a pack of car thieves tried to steal a Milwaukee-area woman's car at a gas station, she didn't run for help. Oh no. She hulked out, jumped on the hood, and screamed her head off until the thief finally ran off. According to WISN, Melissa Smith was gassing up her white Subaru Outback at a BP station near Milwaukee's historic Third Ward on the afternoon of May 24. As she stood there pumping gas and minding her own business, a black Cadillac swung slowly around the front of the Subie and came to a stop just off the front left corner. As Smith turned her back to hang up the pump nozzle, a dude bailed out of the Caddy, crouched down, and snuck into the Outback's driver's seat. "I didn't see him till I saw him get into my car. Or someone was in my car, and had my, 'Oh, hell this isn't happening to me today' moment," Smith told WISN. As soon as she saw the thief in her car, Smith ran around the front then leaped on to the hood. She started yelling and pounding on the windshield as the thief tried to pull away from the pump, but he refused to stop. He tried a couple quick stops in an attempt to shake her off, but to no avail. "He looked at me, and he laughed at me, which really irritated me," Smith said. "He was laughing while I was on my car, and he was trying to throw me off, so zero remorse." Smith clung to the Subaru, shouting and pounding until the thief gave up. He abandoned ship, jumped back into the Caddy, and the group of thieves sped away. Unfortunately, when the thief bailed he left the Subie in gear with Smith still holding on for dear life. "Then I had to chase my car into the street and stop it before it hit somebody else," Smith said. Thankfully, Smith was unharmed in the incident, but the crooks got her purse, phone, wallet, and sunglasses. Milwaukee police are still looking for the suspects, who they say stole the black Caddy before trying to steal Smith's Subaru.
