Torque time | 2017 GMC Sierra HD First Drive

It's not the truck that counts, it's how you use it. It's the heavy stuff you fit in its bed or the extremely heavy stuff that gets hooked up to the tow hitch. The ATV, the Jet Skis, the trailer with more square footage than a Greenwich Village apartment. Perhaps you need to get Seabiscuit or, uh, Mr. Ed to wherever they need to gallop next. In our case, there's a pair of very serious-looking snowmobiles perched atop the bed of a GMC Sierra. They spread out as wide as the extended tow mirrors, and their back halves are dangling precariously beyond the truck. Sterling Archer would be giddy; I'm a little nervous. But only because canyon roads and wide vehicles with a high center of gravity go together like peas and custard. The added weight is no sweat at all. That's because this is the 2017 GMC Sierra HD Denali, a truck with the sort of enhanced power, torque, suspension, and stopping capability expected of a heavy-duty pickup. And for this year, the power and torque get a serious bump courtesy of a new 6.6-liter Duramax turbodiesel engine reengineered from almost the ground up with 90 percent new parts. It's quieter and more efficient and it emits less, while most importantly producing 445 horsepower and 910 pound-feet of torque. That's up from 397 and 765, respectively. Chevy fans will note that the same engine is also available in the updated 2017 Silverado HD. Now, for those keeping score at home, that horsepower is best-in-class but the torque number still falls short of the new Ford Super Duty and its Power Stroke diesel V8's 925 lb-ft. Aw shucks. For the record, GM's engineers didn't seem too concerned that they weren't able to eke out an extra 16 torques just to say they're No. 1. "We wanted to first meet emissions and then deliver the maximum horsepower and torque we could, and deliver it over the widest usability range possible," said chief engineer Eric Stanczak. And let's be honest here, 910 pound-feet is herculean, and once again, a jump of 145 lb-ft. Or one Subaru Impreza's worth. Or 110 more than the best Ram can do on a 2500, and its Cummins turbodiesel's 800 pound-feet was eye-popping not too long ago. (The Ram 3500 maxes out at 900 lb-ft with the right transmission.) Ah, but here's the rub. That Cummins-equipped Ram 2500 can still tow more weight according to SAE-compliant measurements – 17,510 pounds for a Ram crew cab with a short bed versus 13,000 in the similar Sierra 2500. The Ford F-250 can manage 15,000.

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.

The cars and trucks of 'Transformers: Rise of the Beasts'

The latest spectacle in the Transformers franchise is about to hit the theaters. The final trailer was released, giving us peeks at what appears to be a pretty boilerplate story about the end of the world. There's some kind of ancient interplanetary war brewing and it's up to some teenagers to sort it out with the help of their robot buddies. But this is Autoblog, so we're not even going to try to suss out a plot so thin it won't hold a spittle globule's worth of water. We'll just go over the cars. Transformers: Rise of the Beasts | Official Final Trailer (2023 Movie) Porsche 911 Carrera RS 3.8: Mirage So far the star of the film, car-wise, looks to be a blue-on-silver 964 Porsche named Mirage that is voiced by Pete Davidson. It's been the most promoted of the movie cars, even more so than formerly central characters like Bumblebee and Optimus Prime. Except, this isn't just any ordinary 911; it's a Carrera RS 3.8, a European-exclusive model of which Porsche only built 55 units. As the name implies, it came with a bored-out M64 turbo flat-six as opposed to the 964 Turbo's 3.6. It wore the Turbo's wide-body badonk with a bi-level rear wing, but Porsche reportedly stripped out 570 pounds' worth of weight despite embiggening key performance parts like brakes and wheels. Fortunately, no actual RS 3.8s were used in the movie. Producers instead built five cars for different purposes — shooting closeups of actors, jumps, the obligatory driving backwards real fast — out of lesser 911s. However, the sound department did record the engine note of an actual RS 3.8 for accuracy, as the higher crank speeds of the 3.8 have a distinctive sound.  In the original 1984 Transformers lineup Mirage was a Ligier JS11 Formula 1 car, complete with faux Gitanes cigarette branding (on a children's toy!). An F1 racer would raise an eyebrow on the streets, so it made sense to update to a street-legal sports car. If you're wondering why this Porsche isn't the character Jazz, whose original vehicle mode was an ultra-cool Martini-liveried Porsche 935, well, he was remade into a Pontiac Solstice voiced by Darius McCrary during the GM product placement rewrite in 2007's Transformers reboot, then unceremoniously killed. 1977 Chevrolet Camaro: Bumblebee Formerly the franchise star, Bumblebee gets far less screen time in the trailers. He's still a Camaro, but because Transformers: Rise of the Beasts takes place in 1994 he's not a fith-gen.
