2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.

GM to sink over $900M into 4 plants, mostly for a new V8

FLINT, Mich. — General Motors says it will spend more than $900 million to update four factories, with the bulk going to an engine plant in Flint, Michigan, to build the next-generation V8 for big pickup trucks and SUVs. Factories in Rochester, New York; Defiance, Ohio; and Bay City, Michigan, also will see investments, some to make V8 engine components as well as parts for future electric vehicles, the company said Friday. The investments won't create any new jobs, but they will preserve about 2,400 hourly and salaried positions positions at the four sites, the company said. The investments “provide job security at these plants for years to come,” Gerald Johnson, GM's manufacturing chief, said in a statement. Much of the money, $579 million, will go to Flint Engine Operations for equipment to build the sixth-generation small-block V8 that will go into the next round of big pickup trucks and SUVs. The plant now employs about 700 people who also will keep making their current product, a diesel engine used in light trucks. GM, like other automakers, is facing stricter government fuel economy standards and pollution limits starting in the 2024 model year. New vehicles sold in the U.S. will have to average at least 40 miles per gallon of gasoline in 2026, up from about 28 mpg, under new Biden administration rules that undo a rollback of standards enacted under former President Donald Trump. That means the new V8 will have to get better mileage and pollute less than the current versions. Although GM wouldn't release details on the new engine, Johnson said during a news conference at the Flint plant that it would be more efficient than the current version. GM has a goal of selling only electric passenger vehicles by 2035, but Johnson said that's a dozen years out, a period when many customers will still want gas engines. “We know that has a horizon,” he said. “Between here and there, there are a lot of internal combustion customers that we don't want to lose,” he said. In addition to Flint, GM's engine components plant in Bay City, Michigan, will get $216 million to build camshafts and connecting rods, and to machine engine blocks and heads for the new V8 being built in Flint. The plant now employs about 425. The Defiance, Ohio, foundry will get $55 million to build a variety of block castings for the new V8. Included is $8 million for castings to support future electric vehicles, the company said. The plant has about 530 employees.

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.
