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.

GM, Pilot will build EVgo fast chargers at 500 truck stops across U.S.

All of our maps showing electric vehicle charging stations across the U.S. are going to need an update. Today, General Motors, Pilot and EVgo announced plans to work together on a nationwide DC fast charging network. The plan calls for 2,000 charging stalls that can deliver up to 350 kW to be installed at up to 500 Pilot and Flying J travel centers in the U.S. The goal is to have DC fast chargers available in 50-mile intervals across the country. The new charging stations will feature GM's "Ultium Charge 360" branding and "Pilot Flying J" logos but will not be limited to drivers of GM EVs. The plugs will use CCS connectors and be available to anyone. GM EV owners can take advantage of benefits, including the ability to make exclusive reservations, get discounts on charging costs and streamline the charging process with Plug and Charge and in-vehicle apps that can provide real-time charger availability. The first installation phase will take place in 2023, and "the bulk of the installations" should be completed by 2025, EVgo CEO Kathy Zoi said during a conference call with reporters announcing the plan. "We're gonna get going immediately and commence all of that engineering and planning stuff," she said. "We've got a pretty orderly plan." Pilot CEO Shameek Konar said the company expects the new EV charging stations to coexist with the current fuel infrastructure. "An average Pilot Flying J location is about 10 acres," Konar said. "This will be in addition to all of our gas pumps. The way I think about it is, this is a new source of energy that is going to coexist with gas for quite some time. We can debate how long, but we need to serve both groups of customers." Installing DC fast chargers at hundreds of Pilot's travel centers — aka truck stops — means there should be food, drinks, restrooms, WiFi and even showers available while you wait for an EV to charge. Pilot recently announced its “New Horizons” plan that will invest $1 billion in upgrading Pilot travel centers with more premium amenities, including expanded seating and lounge areas. While the exact amount of time it will take to charge an EV using these new stations will vary on the EV and its current state of charge, most EVs can refill from a low state of charge to around 80 percent in 20-30 minutes on a fast charger. The new stations are future-proofed to deliver up to 350 kW, a charge rate that few EVs today can handle.

2020 GMC Acadia refresh brings a new engine, AT4 trim level

It's mid-cycle refresh time for the GMC Acadia, and the updated 2020 model kicks off its changes with a new face. It has a square-jawed grille seemingly pulled straight off the Sierra full-size pickup, and the size is amplified by the slender new LED headlights on either side. At the rear, the LED taillights are taller and more chiseled. A new AT4 trim level adds more visual distinction with black trim and wheels, plus all-terrain tires to make it a little more capable off road. The AT4 also boasts standard all-wheel drive. Under the revised skin, the Acadia hides one of two carryover engines, or a new turbocharged 2.0-liter inline-4. This new engine makes 230 horsepower and 258 pound-feet of torque with the help of a twin-scroll turbocharger. To make it more frugal, it's able to deactivate two of its four cylinders. The turbo engine is standard issue on the SLT and Denali trim levels. The carryover engines include a naturally aspirated 2.5-liter 4-cylinder making 193 horsepower and 188 pound-feet of torque, and a naturally aspirated 3.6-liter V6 making 310 horsepower and 271 pound-feet of torque. The V6 is standard equipment on the AT4 trim. No matter the engine, all 2020 Acadias get a 9-speed automatic transmission. The new transmission also ditches the current Acadia's mechanical shift lever in favor of an electronic shifter with the Terrain's mix of buttons and triggers. It does free up space between the seats, but the button arrangement is still as strange as it was when we first saw it in the smaller crossover. There are a handful of other little upgrades to mention. The suspension has been revised for greater comfort; the infotainment has been revised with a bigger screen, USB-C inputs and customizable profiles; and wireless phone charging is now an option. The updated Acadia goes on sale this fall, and pricing will probably be announced close to launch.
