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.

2016 GMC Canyon Diesel Quick Spin [w/video]

The 2016 GMC Canyon Diesel and the 2016 Chevrolet Colorado Diesel are basically the same truck. This isn't really news – the two midsize pickups have been discussed side by side since their inception. If you stop reading right now, go to our First Drive story from last week, and replace "Colorado" with "Canyon," you won't miss a beat. Samesies. Looks-wise, the Canyon is a bit more polished overall than the Colorado on which its based. The front fascia has a more upscale, yet tough aura, the squared-off headlamps mimic those of the Sierra, and the alloy wheels – especially those on this SLT tester – are a premium touch. Inside the cabin, it's all carryover stuff from the Chevy truck, just with different badges and some unique color/trim combos. So it's a Colorado Diesel with a Canyon treatment. It's the typical GMC updo. But that's fine by me; this thing's a real sweetheart. Driving Notes Talk about smooth operator. This is one of the least harsh diesel engines I've ever tested, with low levels of vibration. Credit for that goes to the fancy German torque converter, as our own David Gluckman detailed in the Colorado First Drive. There's there's also very little in the way of turbo lag in this truck, aiding the silky character. I kind of miss the "turbo moment" woosh of power, but I'll happily trade that for total overall refinement. GMC hasn't released official fuel economy figures just yet, and my drive route wasn't exactly great for testing the ol' miles per gallon rating. I spent about 45 minutes slogging through traffic in Manhattan (perfect place for a diesel pickup, right?), before getting out onto the highway for another 45 or so. The combined trip returned numbers in the mid-20s, but I have to believe this truck can do better. The steering is vague, the body rolls – it drives like a pickup. That said, even though it's on the larger side of midsize, the Canyon is easy to maneuver, sight lines are great, and it's a generally pleasant-handling truck. The 2.8-liter Duramax diesel engine adds about 200 pounds to the Canyon's overall curb weight, but you don't notice from behind the wheel. Braking feel is smooth and solid, and the truck doesn't feel especially nose-heavy. Despite the anti-aero shape, the Canyon delivers a quiet ride with very little wind or road noise. Credit this to all the sound deadening material added to keep unpleasant diesel chugga-chugga-chugga noises out of the cabin.

2021 Chevy Tahoe, GMC Yukon fuel economy and towing capacities go official

Most of the puzzle pieces have fallen into place with GM’s new full-size SUVs, but today we have fuel economy and towing to add to the picture. Numbers for the standard 5.3-liter V8 and upgrade 6.2-liter V8 are out, but GM has held back on the 3.0-liter turbodiesel inline-six for the time being. Those numbers are most likely not ready yet. Minor improvements and decreases are seen throughout the Tahoe/Suburban and Yukon/Yukon XL lineup. Because there are so many variants, weÂ’re going to just lay them out below for you. 5.3-liter V8 2021 Tahoe/Yukon 2WD: 16/20/18 2021 Tahoe/Yukon 4WD: 16/20/18 2021 Suburban/Yukon XL 2WD: 16/20/18 2021 Suburban/Yukon XL 4WD: 15/19/17 6.2-liter V8 2021 Tahoe/Yukon 2WD: 15/20/17 2021 Tahoe/Yukon 4WD: 14/19/16 2021 Suburban/Yukon XL 2WD: 15/20/17 2021 Suburban/Yukon XL 4WD: 14/19/16 As you can see, there isnÂ’t a whole lot of difference between two-wheel drive and four-wheel drive options. You can eke out an extra mpg here and there, but itÂ’s a penalty weÂ’d be happy to live with to have four-wheel traction. The biggest loser in all of this is highway mpg. Chevy has made the trucks bigger and added weight with the independent rear suspension, causing a decrease in fuel economy. For example, a 2020 Tahoe with the 6.2-liter V8 and four-wheel drive is rated at 14/22/17. The 2021 truck drops 3 mpg on the highway and 1 mpg in the combined rating. There are improvements to be found, though. A 2020 Suburban with the 5.3-liter V8 and four-wheel drive is rated 14/21/16. Fuel economy in the city goes up 1 mpg, but you lose 2 mpg on the highway and 1 mpg in the combined rating. ThereÂ’s a bit of give and take here, but at least a slight increase in city mpg has accompanied the greater loss in highway fuel economy. 2021-chevy-tahoe-chicago-01 View 12 Photos As for towing, the Tahoe/Yukon with the 5.3-liter V8 and two-wheel drive has a new 7,900-pound capacity, and the four-wheel drive model is rated at 7,700 pounds. Respectively, those are the best figures youÂ’ll get with the standard towing capacity. Opt for the maximum towing package, and the Tahoe/Yukon capacities go up to 8,400 pounds (two-wheel drive) and 8,200 pounds (four-wheel drive). The numbers all take slight cuts when you go for the 6.2-liter V8. Both the Suburban and Yukon XL offer similar or identical towing figures as their shorter counterparts do.
