2017 GMC Acadia loses 700 pounds, gains everywhere else

Ladies and gentlemen, welcome to Acadia. The 2017 version of the three-row GMC crossover has all kinds of newness. The 2017 Acadia has lost 700 pounds compared to its predecessor thanks to high-strength steels allowing redesigned parts, and the fact that it overall, the vehicle is actually smaller. Length is reduced by 7.2 inches on a wheelbase diminished by 6.4 inches, it is 3.5 inches narrower and sits 3.9 inches lower. The 2016 Acadia was 4,656 pounds, the 2017 is 3,956 pounds. GMC says it will still swallow people, but not as many: the eight-passenger option didn't make the transition, potential three-row trims permitting five-, six-, and seven-passenger configurations. While you lose space, you gain convenience with a split-folding second row featuring tilt-and-slide for both sections. The third-row seats fold flat into the cargo floor, and if the second row is folded as well, cargo capacity improves over the 2016 Acadia, 79 cubic feet compared to 70 cu-ft. A new 2.5-liter four-cylinder brings a second engine option to the spec sheet, returning an estimated 22 city miles per gallon and 28 highway mpg with the help of stop/start tech on front-wheel-drive trims. The new 3.6-liter V6 gets around 310 horsepower, a power bump of about 19 hp, and an estimated 25 highway mpg in front-wheel-drive guise. Towing capacity for that V6 goes down, though, from 5,200 on the current Acadia to an estimated 4,000 pounds. The optional Tow Vision Trailering system will make that pulling easier. Both engines are hooked to a six-speed automatic. Now we can get to its looks. Trademarks like the square, flared wheel arches, dark D-pillars, and wraparound rear side windows made the transition, everything else is new. While weight has gone down, safety's gone way up with internal changes like the splayed chassis members to confront the small-offset test. New active safety upgrades run from from three kinds of automatic braking systems to surround vision cameras, automatic high beam control, a safety alert seat, and a following distance indicator. Buyers can choose from a front-wheel drive, all-wheel drive, or All Terrain model, each with its own electronic drive selector modes. The Normal, Sport, and Trailer/Tow modes are common to the trio. The FWD gets a Snow mode, the AWD adds adaptive 4x4 and Off Road modes; on the AWD, the 2x4 mode disconnects the rear axle from the drivetrain.

2022 GMC Hummer Edition 1 weighs 9,063 pounds

From the beginning, the Hummer line of vehicles has been synonymous with the phrase, "absolute unit." The M998 Humvee turned to civilian use as the Hummer H1 came with a curb weight of 7,560 pounds depending on configuration. The much more urbane Hummer H2 didn't sacrifice much of those gains, putting about 6,615 on the scales. Let us not forget that the behemoth gravitational pull and square-jawed mass were what every Hummer buyer wanted. So, starting with the brand values and customer demand, and adding the fact that electric vehicles are substantially heavier than their ICE counterparts, no one should be surprised that the 2022 GMC Hummer Edition 1 weighs 9,063 pounds. That's just one of the substantial figures GMC included in a self-certification filing submitted to the U.S. Environmental Protection Agency, the document rooted out by Car and Driver. Last year GMC told us the Hummer would weigh 9,046 pounds, which proves again the Freshman 15 (or 16) is unavoidable.  Loaded up with humans and their accessories, the truck's gross vehicle weight rating (GVWR) comes in at 10,550 pounds. It takes a few other big numbers to keep that kind of tonnage on the go. The Ultium battery weighs 2,923 pounds. With a 617-amp-hour capacity at 400 volts, total capacity comes in at 246.8 kWh, specific energy at 158 Wh/kg. Usable capacity is about 85% less, at 212.7 kWh. For the time being, these numbers put every other pack in a production vehicle in the shade. That gargantuan chemical plant in the Hummer's floor powers a 329-mile range the same way a giant fuel tanks feed a truck that gets 8 miles to the gallon. The miles per gallon equivalent figures GMC submitted to the EPA are 51 MPGe city, 43 MPGe highway, 47 MPGe combined. Motor Trend questioned whether GM applied the correction factor used for window sticker numbers; if not, the standard 0.7 correction drops the MPGe specs to 36 city, 30 highway, and 33 combined. However, trucks with a GVWR beyond 8,500 pounds don't need to display fuel economy figures on their window stickers, so don't expect to see any such details on dealer lots. For comparison, the Rivian R1T Launch Edition weighs about 7,000 pounds, and fits a 128.9 kWh battery good for an estimated 314 miles estimated at 70 MPGe.

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.
