GMC shows how the 2022 Hummer could have looked even more futuristic

Excitement filled the room when GMC asked its designers to resurrect the Hummer in April 2019, but a tinge of uneasiness permeated the department after executives locked in an early 2020 unveiling date. Luckily, stylists knew what they wanted early on in the development phase, and preliminary design sketches give us a fascinating look at how they shaped the electric off-roader that ended up making its global debut online in October 2020. Hummer, the brand, unceremoniously shut down in 2010 after General Motors failed to sell it to the Chinese, but its design DNA was so strong that stylists were able to pick up where their predecessors left off. All of the sketches published on Instagram by the official General Motors Design account show a boxy truck with a tall front end, a short windshield, and a generous amount of ground clearance. These styling cues trace their roots to the AM General Humvee that entered production in 1984 and made its combat debut when the United States invaded Panama in 1989. Even the wildest drawings still depict a pickup that's immediately recognizable as a Hummer. Most of the early design sketches wear some variation of the seven-slot grille that characterized Hummer's production models; it's a styling cue that hints at a heritage shared with Jeep under the American Motors Corporation (AMC) umbrella. Oddly, none wear the round headlights seen on the H2, the H3, and the HX concept that nearly became the H4. Was GMC afraid that its Hummer would end up looking too much like a Jeep? And, at least one sketch shows a fold-down windshield, a feature that will not make it to the assembly line. Sketches never reach production without modifications made in the name of packaging and safety concerns, and the Hummer is no exception, but stylists did a good job of reinventing the brand's design language without copying or erasing the past. If the company had stuck around long enough to make a second- and a third-generation H2, odds are it would look a lot like the GMC-branded model that will enter production in a year. GMC remains on track to start 2022 Hummer deliveries in late 2021, though it told Green Car Reports that it still hasn't built a fully functional prototype yet. When it arrives, this outdoorsy pickup will land in a burgeoning segment of the truck market that numerous models (including the Rivian R1T and Ford's electric F-150) will also call home.

Cadillac XT5, XT6, GMC Acadia recalled for two issues

General Motors is recalling three model years of the Cadillac XT5 and XT6, and the Cadillac's GMC sibling, the Acadia. The first recall has to do with the rearview camera. On 2020- and 2021-model-year XT5s, XT6s, and Acadias optioned with Surround Vision, insufficient crimping for the coaxial cables could cause a degraded signal from the rear camera, or cause the signal to fail. With all passenger vehicles required to have a working rearview camera, that's not an ideal situation. Only crossovers with Surround Vision are affected. The population at issue counts 95,231 vehicles, build dates being: XT5s produced from May 1, 2019 to June 23, 2021 XT6s built from February 25, 2019 to June 24, 2021 Acadias built from May 6, 2019 to June 24, 2021  The automaker hasn't been informed of any crashes or injuries related to the problem, and will begin mailing letters notifying owners of the issue on November 7. The fix is a trip to the dealer to have the cables inspected and replaced if necessary. Concerned customers can contact Cadillac customer service at 800-458-8006 or GMC customer service at 1-800-462-8782, then refer to GM's recall number, N222378380. Alternatively, they can get in touch with the National Highway Traffic Safety Administration (NHTSA) Safety Hotline at 888-327-4236 (TTY 800-424-9153), or go to www.nhtsa.gov, and refer to campaign number 22V709000. Another recall concerns just the 2023 Cadillac XT5 and XT6 and 2023 GMC Acadia units that were built on August 9, 2022. That day, a printer in the Spring Hill, Tennessee, Assembly Plant malfunctioned, producing vehicle labels for the driver's side B-pillar with illegible tire size information. That's a violation of a subsection of Federal Motor Vehicle Safety Standard No. 110. Only 24 units are affected, the fix being a jaunt to the dealer for a label with readable information. Owners who don't want to wait until November for letters from GM can contact Cadillac customer service at 800-458-8006 or GMC customer service at 800-462-8782, and mention recall number N222381690. Or they can head to the NHTSA Safety Hotline at 888-327-4236 (TTY 800-424-9153), or www.nhtsa.gov, and refer to campaign number 22V708000.

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.
