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.

Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.

GMC could have used Jeep's prized grille design on its born-again Hummer

General Motors confirmed it's bringing the Hummer nameplate back on an electric, GMC-badged pickup by publishing a dark photo of its front end. The battery-powered drivetrain under the sheetmetal represents a tectonic shift, but we noticed another flagrant break with tradition: it wears six slot-like inserts instead of seven like on every previous Hummer and countless Jeeps. Adding an extra slot wouldn't have landed GMC in hot water. The seven-slot grille has historically been associated with Jeep, and the company proved it's willing to go to significant lengths to ensure another automaker — especially one it perceives as a rival — doesn't use it. Parent company Fiat-Chrysler Automobiles (FCA) bitterly sued Mahindra over the Roxor's design, including its five-slot grille, and won in 2019, forcing the Indian firm to unveil a redesigned side-by-side for the 2020 model year. And yet, stylists would have very likely been able to get away with it on the Hummer. While General Motors owns Hummer, the brand traces its ancestry to 1970, when American Motors Corporation (AMC) purchased Jeep from Kaiser and changed the name of its General Products Division to AM General Corp. The division manufactured the rear-wheel drive, CJ-based DJ for the United States Postal Service and began developing the Humvee in 1979. Jeep and AM General went their separate ways when Renault began investing in AMC. Foreign companies weren't allowed to own defense contractors, and AMC had more to gain by gradually selling out to Renault than by keeping AM General, so it divested the division to LTV Corporation in 1983. Humvee production started shortly after, but no one protested its seven-slot grille because there was no risk of it stealing sales from a comparable Jeep model. It was manufactured exclusively for the U.S. Army, and civilian sales weren't planned. H2SUV View 4 Photos The original civilian Hummer released in 1992 must have raised more than a few eyebrows but, here again, it didn't directly compete with one of Jeep's off-roaders, so no one complained. It was huge, correspondingly expensive, and its portal axles made the YJ-generation Wrangler wet its pants. It's the H2 concept (pictured above) unveiled at the 2000 Detroit Auto Show that set off alarm bells in Auburn Hills. DaimlerChrysler's lawyers counted the slots in the chrome-plated insert that dominated its front end and shuddered when they reached seven.
