GM Defense shows Hummer EV-based military truck concept

GM Defense wants to convince the U.S. military that it has even more of what the military needs. During this week's Modern Day Marine 2023 exposition in Washington, D.C., GM Defense showed a new tactical vehicle concept based on the GMC Hummer EV platform. Called the Electric Military Concept Vehicle (eMCV), it uses the same Ultium platform and drivetrain as the retail Hummer EV. That means a 200-kWh battery (usable) powering three motors making 1,000 horsepower, with the two motors in back capable of torque vectoring, the single motor in front fitted with a locking diff. Upgrades over the dealership version include Fox shocks working larger 37-inch tires and heavy-duty brakes. The redrawn front and rear bumpers improve approach and departure angles. The tube chassis and lack of body panels would shed some of the Hummer's prodigious weight, nevertheless, range is reduced as a result of the other mods that reduce aerodynamic efficiency. Among said mods to the six-seater is a 46-inch gun ring and a swing side-arm mount when it's time to clock in. The estimated range drops to 300 miles from the 329 on the retail Hummer EV. Being mostly electric – more on that in a moment – the eMCV has features Silent Drive and Silent Watch driving modes could get fighters on-station with minimal noise.Plugged into a fast charger capable of 350 kilowatts, GM Defense says 12 minutes gets 100 miles of range. But when silence isn't a necessary factor, this is a series hybrid. GM Defense added a 12-kW diesel generator that can provide "limited charging and propulsion," which could also help charge "mission-critical equipment." A while back, the Army purchased a commercial Hummer EV for evaluation. The military didn't request this new concept, a GM Defense spokesperson telling Defense News it was built as a sign of potential. "We're trying to showcase what is in the realm of the possible just so we can get the discussion going and help shape [the military's] future requirements," the spokesperson said. "They get to see the different sizes and how to customize it, the different options." The eMCV sat on the trade show floor next to GM Defense's All-Electric Military Concept Vehicle, a Chevy Colorado-based Infantry Squad Vehicle (ISV) powered by a 60-kWh battery juicing an e-crate motor with 200 hp and 266 pound-feet of torque. The eISV was also built as a demonstrator without military input.

UAW Chief Shawn Fain disrupts Detroit's labor tradition

He's known to quote the Bible and Nation of Islam civil rights leader Malcolm X. He's a social media fanatic who keeps the pay stubs of his union member grandfather in his wallet. And now, Shawn Fain is representing nearly 150,000 auto workers in one of the biggest labor strikes in decades. In taking action against all three Detroit carmakers, Fain, the head of the United Auto Workers, has remade the strategy of the union he leads, choosing a bolder, much riskier path than his predecessors after he won office by a narrow margin in a first-ever direct election earlier this year. The strike started as the clock hit midnight on Friday, and followed Fain's decision to open negotiations with Ford Motor, General Motors and Stellantis simultaneously and eschew public niceties involving choreographed handshakes that famously kicked off previous negotiating efforts. The strategy is not without risk. A weeks-long strike would hit workers who live paycheck to paycheck, while the Detroit Three automakers have billions in cash to withstand the walkout. Fain, 54, has made creative use of social media, appearances on network and cable news programs and alliances with high-profile progressive politicians such as U.S. Senator Bernie Sanders, to reframe the UAW's contract bargaining as a battle to re-set the balance of power between workers and global corporations. He has rebutted automakers' concerns about labor costs by pointing out that they have poured billions into share buybacks to benefit investors. "If they’ve got money for Wall Street they sure as hell have money for the workers making the product," he said. “We fight for the good of the entire working class and the poor." In lengthy social media talks to UAW members, Fain alternates quoting Bible verses with the use of charts and graphs to dissect wage and benefit offers from the automakers - details his predecessors kept behind closed doors during bargaining crunch time. Fain, in his unorthodox approach, ran what amounted to a public auction among the companies to push each one to top the other to avoid a costly walkout. Prior UAW presidents picked just one automaker to set a pattern for the other two. Over and over, Fain has told UAW members at the Detroit Three that they can reverse 20 years of wage and retiree benefit concessions, stop further plant closures and end a seniority-based, tiered compensation system that pays new hires as much as 44% less than veteran workers.

2019 GMC Sierra AT4 First Drive Review | Off-road overkill

The road ahead is dirt with a rut here and a rock there. Brush keeps a respectable distance on the right side, the edge on the left gradually falls away into the valley below. The grade is nothing your treadmill couldn't duplicate and traction is pretty good. Honestly, a couple in their Subaru Crosstrek could pop up here for a picnic. The 2019 GMC Sierra AT4 we're driving is therefore complete overkill. But at least it looks the part as it trudges up this uncharacteristically verdant mountain with San Diego in the distance to the north and Mexico to the south. Its special, dechromed AT4 grille has a purposeful appearance, but tastefully lacks the show-off machismo of Ford and Ram's off-roading models. The red tow hooks are a nice touch and the dark-accented 20-inch wheels wrapped in all-terrain rubber are just the right size beneath a suspension that is raised an extra 2 inches from every other Sierra. That would be one of the key elements that differentiates the AT4 as the Sierra's off-roading model – GMC's answer to the Chevy Silverado's Trail Boss trims. In fact, their mechanical enhancements are identical. Besides the 2-inch lift, the suspension features off-road-tuned Rancho monotube shocks. There's also a locking rear differential, a two-speed transfer case, skid plates and those tow hooks. The 5.3-liter V8 with Dynamic Fuel Management is similarly standard, but unlike the Silverado Trail Boss, the Sierra AT4 offers the 6.2-liter V8 good for 420 horsepower and 460 pound-feet of torque as a roughly $2,500 option. That's the engine we have and it delivers the expected punch, complete with a satisfyingly snarling exhaust note. However, as observed in back-to-back drives with these two available engines during the Silverado launch, the 6.2 certainly isn't necessary. The 5.3-liter is seriously capable and the bigger engine is largely for those who want to have the biggest number possible emblazoned on the fender. It's overkill, which in this particular environment, is fitting. Besides the available engine upgrade, the AT4 also goes beyond its Trail Boss counterpart by dipping into the Sierra Denali's tool box. Its MultiPro tailgate is standard equipment, allowing for six different configurations, the most notable of which include a means of more easily reaching into the bed and a drop-down step that eases entry into the bed. GMC's considerable touting of that last element is rife with hypocrisy given GM advertisements that mocked Ford's similar feature.
