2023 GM full-size SUVs get Super Cruise expansion pack first

In August, GM announced it had doubled the size of the network of roads available to its Super Cruise hands-free driving feature. Joining the options list in 2017, Super Cruise had been limited to divided interstate highways in the U.S. and Canada. The expansion opened 200,000 miles of additional divided interstate highway as well as major, undivided highways. Both coasts benefit, but there will be a lot more relaxing motoring on the East Coast especially. North of the border, six of the 10 Canadian provinces add enabled roads. Problem is, no GM vehicles have been able to take advantage of the boon. That changes this month, the automaker saying four of its full-size SUVs in specific trims are first in line to make use of the expansion. The SUVs are: 2023 Chevrolet Tahoe Premier and High Country 2023 Chevrolet Suburban Premier and High Country 2023 Cadillac Escalade, Escalade ESV, and Escalade-V 2023 GMC Yukon Denali Ultimate  The vehicles need to have been built on or after October 3, 2022, a production timeline GM says should put the first examples in customer hands this month. The least expensive way to get into Super Cruise is with the two-wheel drive, $77,625 Chevrolet Tahoe Premier with the 3.0-liter inline-six Duramax diesel and the Advanced Technology Package. Vehicles that use the GM's Vehicle Intelligence Platform electrical architecture and already have Super Cruise will receive an over-the-air update "in the coming months" to access the new roads, at no cost to owners. Since other products like the Cadillac CT4 and CT5, Chevrolet Silverado, and GMC Sierra work with the VIP platform as well, they probably aren't far away from the extra capability and they'll bring a lower financial bar to entry.  Related video:

2024 GMC Hummer EV SUV Second Drive Review: Moab made easy

MOAB, Utah — The title of our First Drive of the 2024 GMC Hummer EV SUV included the phrase, "It's big, but this elephant can dance." The truck earned that compliment after a day of squeezing through San Francisco lanes and the slightly-more-commodious back roads in Napa Valley. But an SUV can't be called a supertruck without equivalent mastery on dirt, so GMC led a posse of media to Moab, Utah to run the Hummer's favorite stomping grounds. What happens when you subtract 20 inches of overall length and nine inches of wheelbase from a megafauna pickup? You find the dancing doesn't stop where the pavement ends. Allowed to roam Moab's challenging terrain — and ample room — the SUV is more than ready to do the Hokey Pokey and turn itself around. Admittedly, we knew this from our First Drive of the Hummer SUT two years ago, also performed among Moab's red rocks and red dust. The two variants share the same tricks, and GMC engineers chose Moab for prototype development, so there was no question of successfully navigating the trails. The SUV's simply nimbler about than the SUT. Clearance angles are better all over. Compared to the SUT, the SUV's 49.6-degree approach angle is just 0.1 better, but the 49-degree departure angle is 10.6 degrees better, and the breakover angle is 2.2 degrees better. Having four-wheel steer to rotate the SUV's shorter wheelbase shrinks the already tiny turning circle by 1.7 feet, to 35.4 feet. That's only four feet wider than a BMW i3, but 14 feet more compact than a GMC Sierra Crew Cab with the Short Box. And there are 'only' 15 standard cameras on the SUV, one shy of the 16 cameras in the SUT; the pickup adds an angle on the cargo bed the SUV doesn't have. Our 3X trim packed three motors producing a combined 830 horsepower and 1,200 pound-feet of torque. The $9,995 Extreme Off-Road Package threw on rock sliders with integrated steps that can support 1.5 times the Hummer's weight, full underbody skid plating, two additional underbody cameras front and rear, an electronically locking mechanical front differential for the single motor on the front, a virtual rear differential (programming that makes the two rear motors behave like a locked diff), heavy-duty ball spline half shafts, tow hooks and 18-inch black wheels on 35-inch Goodyear Wrangler Mud-Terrain tires.

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
