GMC's electric Hummer could someday serve alongside the Humvee in the U.S. Army

Every civilian Hummer model traces its roots to AM General's Humvee, which made its combat debut when the United States invaded Panama in 1989. Fast forward to the 2020s, and the tables have turned. The born-again Hummer that will arrive with an electric powertrain and a GMC emblem could spawn a military-spec truck. "[The upcoming Hummer] is a full-size truck with 400 miles of range and 1,000 pound-feet of torque, it's a very highly capable vehicle. That could provide a great base platform for an electric vehicle to be used in the military context," said David Albritton, the president of General Motors Defense, in an interview with GM Authority. Although he didn't sketch out the Hummer's role in a battalion, its range, torque, and dimensions would theoretically make it well-suited to carrying soldiers, weapons, and/or gear like radio equipment. It wouldn't necessarily look like the production model (shown above in a preview image). General Motors Defense might use its basic platform and its powertrain technology to build a purpose-designed off-roader, like it did with the Colorado Infantry Squad Vehicle (ISV) it will soon begin manufacturing for the Army. The ISV shares 90% of its parts with the regular-production Chevrolet Colorado, but the two vehicles look nothing alike. Securing a contract with the American military is easier said than done, and Army officials haven't publicly expressed an interest in sending the upcoming Hummer into a war zone. We'll learn more about what a battle-ready electric truck could look like after the showroom-bound model makes its debut. In the meantime, Humvee production continues, and AM General introduced a comprehensively updated model named NXT 360 in 2018. Related Video:     Green GMC Hummer Truck Electric Military

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

2019 GMC Sierra shows off new headlights in Los Angeles

Despite being just three weeks in to 2018, it's not too early to dub this the year of the truck. At last week's Detroit Auto Show, we saw the debuts of the 2019 Chevy Silverado, 2019 Ram 1500 and the return of the 2019 Ford Ranger. As with every new Silverado, a sister vehicle follows from GMC. Just take a look at these new spy shots of the 2019 GMC Sierra 1500. These photos were taken out in Los Angeles, presumably for some warm weather testing outside of Michigan. At the Silverado's debut, GM VP Mark Reuss said there would be a significant difference between the Silverado and Sierra with this new generation. The grille on the Sierra appears to be far more upright and rectangular, contrasting the rounded look of the new Silverado. The headlights are larger and more upright. The same goes for the foglights. The profile and rear look fairly similar, though the fenders on the Sierra are more squared off. While we don't know what will rest under the Sierra's hood, expect it to share powertrains with the Silverado. That would mean updated versions of the 5.3-liter V8 and 6.2-liter V8 would be joined by 3.0-liter inline-six diesel. Look for the new Sierra as soon as the Chicago Auto Show next month.
