Hummer EV range listed at 334 miles in MyChevrolet app

Forums of late have been cracking for interesting news, the Hummer Chat forum next in line to keep us intrigued. When member BahamaTodd updated his MyChevrolet app to version 5.7.0, he clicked through to the Energy Assist page and found three GM electric vehicles listed, plus their estimated range figures on a 100% charge. One was the 2022 Chevrolet Bolt, rated for 259 miles, the second was the 2022 Chevy Bolt EUV, rated for 247 miles. The third was an unexpected entry, being the 2022 GMC Hummer EV pickup, listed as able to go 334 miles on a full charge. When BahamaTodd clicked on the Hummer, a map appeared with a dotted line outlining the entire geographical area available to him based on his current location. The figures for both Bolts are the official EPA estimates. The mileage figure for the Hummer is a mystery, as is why it's popped up here in the MyChevrolet app instead of the MyGMC app. The EPA hasn't certified the 2022 Hummer yet, so that's not the source. On the other hand, a little more than a week ago, GM said the Hummer EV could go 350 miles or more based on the automaker's estimates. We assumed GM was referring to the Hummer Edition 1, the sold-out launch model which will be the only trim produced for the 2022 model year, fitted with three electric motors making a combined 1,000 horsepower. The first and safest assumption is that the app data is placeholder information, not intended to be spread on the Internet and dissected. If it does apply to a Hummer EV, it could denote a specific trim or options. The Edition 1 will be available with street tires. It's perfectly reasonable to believe the chunky, 35-inch knobblies that shown in all the press materials could eat up 16 miles or so of range, about a 4.8% loss. Or GM's range estimate could have been meant for one of the future Hummer EV variants, like the slightly less-powerful tri-motor EV3X with 800 hp, the 625-hp dual-motor EV2X, and the base, 625-hp dual-motor EV2. With pre-production of the Edition 1 slated to begin at GM's Factory Zero any day now, answers shouldn't be long in coming.  Related video: This content is hosted by a third party.

2019 GMC Sierra carbon fiber bed: How it's made

FORT WAYNE, Ind. — The redesigned 2019 GMC Sierra has some pretty nifty features, and the one that has had the most attention is the MultiPro flipping and folding tailgate. But the Sierra also features the first-of-its-kind carbon fiber truck bed. It's interesting, of course, for its capabilities, such as being 62 pounds lighter than the all-steel box. It even adds more cargo volume since the material can be assembled and shaped differently from steel. As it turns out, the assembly process is cool, too, which we learned when GMC invited us to see the beds being made. Every GMC carbon fiber bed starts out as perfectly flat sheets of thermoplastic carbon fiber. The sheets consist of a mix of fibers and resins, a bit like the molded carbon fiber parts Lamborghini uses. The sheets are manufactured by Japanese company Teijin, which collaborated with GMC to develop the bed. They're all delivered to Continental Structural Plastics (CSP) in Fort Wayne, Ind., for construction into the actual bed. The company, a subsidiary of Teijin, makes a wide variety of composite and plastic parts for the car industry, including body panels for the C7 Chevy Corvette. The rectangular sheets are cut to shape and stacked up at a giant stamping press. Robots pick up sheets and slide them onto a conveyor that goes into a large oven. The heat softens the parts so they can be stamped. The large primary bed parts such as the base are stamped by CSP's enormous 3,600-ton press, and the smaller ones go through a 1,000-ton press. Each press can do different parts using different stamping dies, and CSP switches between dies to produce different batches of parts. After stamping, the parts roll out mostly ready for assembly, but there are rough edges that are trimmed off by water-jet cutters. These cutting machines also create holes for fasteners and for parts such as tie-down hooks and lights. The stamping process also provides the carbon fiber bed with a unique Easter egg. On the bottom of the base of the bed, there are two words: "Connors Way." This is a tribute to Tim Connors, who was the chief engineer of manufacturing at GM and a strong proponent of the carbon fiber bed. He was tragically killed in a motorcycle crash a few years ago. The words were added to honor him, and they were fortunately approved for production. There are some components to the bed that aren't stamped from the flat sheets of material.

GM recalls Chevy Express, GMC Savana over rollaway concern

The National Highway Traffic Safety Administration has issued a recall notice for a small number of General Motors fullsize vans due to possible rollaway concerns. On certain 2013 Chevrolet Express and 2013 GMC Savana models, it is possible to remove the key from the ignition without the shifter being in park.
Only 980 total units are being affected by this recall, and GM is fixing the issue by replacing the ignition cylinder and associated keys. Affected Chevy vans were built during most of November and December while its GMC counterpart was only built for a week in November. The recall goes into effect on January 23, and to find out if your vehicle applies to the recall, the GM and NHTSA contact numbers can be found on the official recall notice, which is posted below.
