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.

Electric pickups compared: 2025 Ram 1500 REV specs vs. Silverado EV, F-150 Lightning

Now that the 2025 Ram 1500 REV has been revealed, along with its most important specifications, we now have information on all of the mainline Big 3 electric full-size pickup trucks. So it's time to see how the numbers stack up, because trucks are all about numbers. We'll see how the Ram compares to the power, battery capacity, payload, towing and other features of the 2024 Chevy Silverado EV and the 2024 Ford F-150 Lightning. Power and torque The Ram has just one powertrain option. It features two electric motors making 654 horsepower and 620 pound-feet. That gives it the most powerful standard powertrain, if not the most torque, as the Chevy Silverado EV has 510 horsepower and 615 pound-feet of torque, while the F-150 Lighting has 452 horsepower and 775 pound-feet. But the Chevy and Ford each have upgraded motor combinations. The Silverado is the most potent with 754 horsepower and 785 pound-feet, and the F-150 has 580 horsepower and 775 pound-feet. The GMC Sierra EV will also be available with this more powerful pair of motors, and most of its specifications will be the same as the Silverado. There are a couple of exceptions which we'll note when they come up. All three trucks come standard with dual motors and all-wheel drive, regardless of output, battery or trim level. They're all available with locking rear differentials, too. Ford F-150 Lightning front low View 48 Photos Battery, range and charging The Ram is packing some serious packs of batteries. The standard model gets 168 kWh and an estimated range of 350 miles. And the optional 229-kWh pack is estimated to deliver 500 miles of range. That's more capacity and range than the others. It also boasts an 800-volt battery system that allows for close to 350-kW charging. The Ford F-150 Lightning has a base battery of 98 kWh with a range around 230 miles. Optional is a 131-kWh pack with between 300 and 330 miles of range, depending on other vehicle specifications. It's the slowest charger, only allowing 150-kW charging maximum. The Silverado EV's battery specs are a bit nebulous. At launch, it will only be available with one battery pack option that GM claims will provide around 400 miles of range. The company didn't give an exact capacity, though. We would guess its size falls between the Ram's 168 and 229 kWh packs. A smaller battery pack will be offered later, with a shorter but unknown range. The Silverado can use 350-kW fast charging like the Ram.

Hacker jury rigs Amazon Echo into voice-controlled remote start

A lot of automakers have smartphone apps to start, lock, or unlock a connected car. Some automakers will even let you do that with a smartwatch. Then, there's YouTube user Jryanishere, who decided to use Amazon's chatty Echo voice-controlled, internet-connected information thingy. Yes, we said thingy, because we aren't really sure how else to describe the Echo. While the Echo system has received a hearty ad campaign – featuring Alec Baldwin asking Amazon's virtual assistant, Alexa, questions and ordering socks – we think this might be the first really useful thing we've seen it do. Using a MacBook, a Raspberry Pi, an Echo, an OBDLink plug-in, and his 4G LTE-equipped GMC, Jryanishere has basically made a voice-controlled remote-start system. Now, like so many voice-controlled things, this strikes us more of an extravagance than something that's functionally worthwhile. After all, the remote start on the a GMC keyfob isn't exactly rocket science. You can check out the Echo in action up top. Jryanishere gives a pretty thorough breakdown of how the setup works in the video above, but if you're at all into this sort of technological mischief, you'll want to watch (and check out the hilariously detailed blog explaining the job).
