U.S. Army purchases GMC Hummer EV for Light Recon Vehicle testing

The military has been analyzing alternative powertrains for a while, and working with GM vehicular products in that field for at least seven years. In 2016, we got a look at a rebodied Chevrolet Colorado ZR2 with a hydrogen fuel cell powertrain developed by GM and the US Army Tank Automotive Research Development and Engineering Center. In 2017, the automaker created its GM Defense division, winning two contracts for conventionally powered trucks in 2020 and 2021. The Detroit Free Press reports that alt-energy is heavy in the frame, the Army having opened a bid for an electric Light Reconnaissance Vehicle (eLRV). Ten companies showed up with product for a demo last year, at least two of which were electric. The U.S. military's largest branch already purchased a single Canoo EV for testing, now it's also bought a new GMC Hummer EV. It's possible that the specific capabilities of an EV are responsible for the Army's quest. The branch canceled its previous LRV program in 2016 that intended to replace the Scout HMMWVs, which were purpose-built versions of the ubiquitous old Hummer. Military.com wrote that the parameters for that search were a rig that could "carry six soldiers, with a total payload 2,100 pounds. The vehicle must not exceed 11,669 pounds so it can be carried internally or sling-loaded by a CH-47 Chinook helicopter. The vehicle must be capable of mounting a weapon system, such as a 30mm cannon, which can engage targets accurately at a range of at least 1,000 meters." Last November, CNBC reported GM Defense was working on a Hummer EV-based military vehicle. Hummer being Hummer, it's likely GM began exploring the martial route once it greenlit the return of the brand. Last year, Defense Secretary Kathleen Hicks told CNBC, "Electrifying the non-tactical fleet, that’s a no-brainer," but the search for an eLRV signals an eye on something more intense than shuttling troops. Breaking Defense reported in 2020 that the Army was "working with a non-profit consortium of more than 200 companies and universities developing clean transportation technologies, CALSTART." Task and Purpose said the Army's brief for eLRV missions was, "'enhanced mobility, lethality, protection, mission load capacity, and onboard power' for six soldiers to conduct both mounted and dismounted reconnaissance and surveillance missions for Infantry Brigade Combat Teams." That's not necessarily frontline service, but it's not necessarily a garrison shuttle, either.

2017 GMC Canyon steals Cadillac's V6 for a little more power

GMC is fortifying the Canyon with a new powertrain and two new trim levels for 2017. GMC will give the Canyon the 3.6-liter V6 found in the Cadillac ATS, CTS, CT6, and XT5 crossover. The engine will be matched to an eight-speed automatic transmission, which also can be found on Cadillacs, the new 2017 Colorado, and other General Motors vehicles. The new engine comes with variable valve timing, improved direct injection, and Active Fuel Management, which is a form of cylinder deactivation that shuts off two cylinders to increase fuel efficiency and performance. Power is up from 305 to 308 horsepower, while torque increases from 269 to 275 pound-feet of torque compared to the old 3.6-liter V6. With the new transmission, the Canyon benefits from a higher first gear ratio, which should help drivers get off the line more easily when towing large cargo, and lower overdrive ratios for improved fuel efficiency. The 2016 model had a six-speed automatic. The Colorado also gets the eight-speed transmission for '17. GMC previously announced the All Terrain X and Denali models. The All Terrain X trim is offered on the SLE model and comes with the new 3.6-liter V6 engine or the 2.8-liter Duramax turbo-diesel. The All Terrain X gets Goodyear Wrangler DuraTrac P225/65R17 all-terrain tires, a body-color grille surround and matching rear step bumper, bespoke 17-inch aluminum wheels, and a spray-on bedliner. The truck also is fortified with Hill Descent Control and an off-road suspension. The Denali carries the flag as the most luxurious Canyon model and gets a Bose seven-speaker audio system, more chrome, and interior upgrades. In addition to the new models and the powertrain, the 2017 Canyon will be offered with new colors – Dark Slate Metallic, Mineral Metallic, and Red Quartz Metallic – a new IntelliLink radio with a seven-inch touchscreen, a heated steering wheel as an optional extra, and Standard Teen Driver Mode. The 2017 Canyon, with all of its changes, will be available in the fourth quarter of the year.

GM 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.
