Hummer teases crab mode, reveal set for Oct. 20

DETROIT — GMC confirmed it will reveal the Hummer electric off-roader Oct. 20 and released a video teasing the vehicleÂ’s so-called crab mode. Crab mode allows the Hummer to move diagonally and is enabled by the vehicleÂ’s four-wheel steering. The video shows tires, and well, a crab. “When you're in the really difficult terrain, this just gives you unparalleled maneuverability,” said Duncan Aldred, global vice president of Buick GMC. The Hummer will be offered as truck and SUV models, and customers will be able to make reservations beginning on the reveal date. Deliveries are expected to begin in fall 2021. The Hummer was supposed to be revealed May 20, but was delayed due to the Covid-19 pandemic. The Hummer was teased in a Super Bowl ad this year with NBA superstar LeBron James, who is the vehicle's frontman. It will have several EV powertrains which General Motors calls Ultium, and the most capable variant will have an estimated 1,000 hp and hit 60 mph in three seconds. The Hummer will also offer removable roof panels. “This is very much going to be a luxury vehicle which competes against a broad spectrum,” Aldred said Monday on a conference call with reporters. The Hummer will take aim against a variety of vehicles, including the four-door Bronco, RivianÂ’s truck and SUV and the Jeep Wrangler 4xe. Aldred is optimistic the return of the Hummer name will help GMC carve its niche in this growing segment of trucks and SUVs with varying degrees of electric propulsion and off-road capability. GM sold vehicles under the Hummer brand from 1992-2010, before scrapping it in the wake of GMÂ’s historic 2009 bankruptcy and restructuring. Hummer is relaunching under the GMC umbrella. “ItÂ’s real desirability, itÂ’s almost cult-like status,” Aldred said. “I think a huge amount of people are going to have interest in this.” GM, which is re-emphasizing its defense division, could also repurpose the Hummer for military use, perhaps as transport vehicles. Hummers are descended from the Humvee, which is still used by U.S. forces.

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.

GMC boss wants a Jeep Wrangler rival

Challengers come and challengers go, but the Jeep Wrangler continues to push forward even after vehicles like the Toyota FJ Cruiser and the entire Hummer brand have been shut down. Now GMC reportedly wants to take a stab at the quintessential Jeep, as well.
The news comes directly from Buick-GMC vice president Duncan Aldred, speaking with our compatriots over at Edmunds. Although Aldred said there are no plans currently on the table to expand GMC's lineup beyond the current range, "there is plenty of room everywhere in the hierarchy."
That could include a rival to the Wrangler, as well as a flagship luxury SUV positioned above the current Yukon Denali (pictured above). Just when (or for that matter, if) such models might come into fruition remains a big question mark, but it's certainly interesting to see what GM's dedicated truck brand has on the drawing board.
