Next-gen GMC Sierra spied with diesel power

The next generation of GM trucks is arriving soon, and we're expecting a huge leap forward over the current lineup. The Chevy Silverado and the GMC SIerra sell extremely well, but haven't done much to move the segment forward in a long time. The Ford F-150 has an all-aluminum body and turbocharged V6 power. The Ram 1500 gained a diesel and coil spring suspension. These spy shots show that diesel may be in the cards for GM. Some quick shots and copious use of flash show what is most likely a tank for diesel exhaust fluid and a diesel particulate filter, both necessary equipment for any modern diesel. It's unclear what form factor that engine will come in, though GM has a number of engines to choose from, including the 2.8-liter inline four that's found in the Colorado and Canyon, though that may be a little light duty for the Silverado and Sierra. Other rumors surrounding the trucks suggest a move to an aluminum cab while retaining a steel bed. That seems like a reasonable move for GM, even if the company was attempting to shame Ford for its move to aluminum a few years ago. Look for more news as early as the Detroit Auto Show in January.

2021 GMC Canyon AT4 Off-Road Performance Edition is ready to hit the trail

GMC introduced a more capable Canyon AT4 named Off-Road Performance Edition that gains modifications like skid plates and a beefier suspension. It can venture further off the beaten path, but it won't get there faster. Based on the AT4, which is already better suited to venturing into the woods than the standard Canyon, the Off-Road Performance Edition gains a taller suspension and loses its sizeable front air dam to offer a 30-degree approach angle. GMC knows adventurers will be tempted to put that figure to the test, so it also added skid plates made with 5/32-inch aluminum to protect the radiator, the front differential, the steering gear, and the oil pan. Full-length rock rails on both sides shield the rocker panels from expensive encounters with boulders and other obstacles. Finally, the Off-Road Performance Edition stands out from the AT4 with specific 17-inch wheels painted in gloss black, black AT4 logos, and black exhaust tips. 31-inch Goodyear Wrangler tires come standard. Changes in the cabin are limited to floor liners. Out back, the cargo box receives a spray-in liner. Don't look for Ram 1500 TRX-like performance, because it doesn't sound like GMC made any major mechanical modifications to the Off-Road Performance Edition. Power comes from a 3.6-liter V6 that sends 308 horsepower and 275 pound-feet of torque to the four wheels via an eight-speed automatic transmission and an automatic locking rear differential provided by Eaton. AT4 buyers can order a 2.8-liter Duramax turbodiesel four-cylinder with 181 horsepower and a stout 369 pound-feet of torque on tap for an additional $4,375, but there's no word yet on whether this fuel-saving engine will be available on the Off-Road Performance Edition, too. GMC's 2021 Canyon AT4 Off-Road Performance Edition will go on sale later in 2020, though pricing information hasn't been announced yet. For context, the standard AT4 costs $39,395 in its most affordable configuration.  

How the Ram Multifunction Tailgate compares to Ford, GMC, Honda

Ram just announced its Multifunction Tailgate — a descriptive if not very creative name. It's an asymmetrical barn-door arrangement, which can both fold down like a conventional tailgate or swing open like a gate. There's a new bed step, but unlike Ford or GM, the step isn't part of the tailgate itself. Rather, it kicks out from under the bumper (as opposed to out from under the driver's side of the rear bumper in its previous incarnation). So let's just focus on the tailgate functionality. A video of the Ram Multifunction Tailgate in action is above. For one, either of the swinging tailgate sections can be opened independently. They open to a full 88 degrees. In conventional flip-down mode, the tailgate works just like a normal one, too, with a 2,000-pound rating. The bottom line is that while it gives a variety of types of access to the load area, it doesn't "do" anything else. It's a $995 option on any Ram 1500. Its closest analogue is the Honda Ridgeline, which works basically the same way, but on that truck the tailgate swings as one piece. And the Honda's load rating isn't as hefty as the Ram's tailgate: 300 pounds. As Honda says, that's sufficient to hold the weight of the part of an ATV hanging out of the bed, or something similar, but it's a lighter-duty unit (and a lighter-duty truck) than the Ram's overall. Let's also get Ford's one-trick tailgate out of the way before comparing to the more analogous, and complicated, GM MultiPro. A bit of trivia: Ford's optional Tailgate Step is actually designed and supplied by Multimatic, better known as the outfit that builds the Ford GT and produces the DSSV spool-valve shocks. This step has been available for years. It pulls out of the top edge of the tailgate when the tailgate is lowered, deploying a single step. A separate handle pulls out from beside the step and flips up, giving a handhold. While it was initially (and infamously) mocked by competitors, with load floor heights as high as they are it's better than toting around a stepstool. It's currently a $375 standalone option. Now we get to the GMC MultiPro tailgate, the most complicated and multi-functioned around. It's essentially a tailgate within a tailgate, with a fold-out stopper that deploys from the inner tailgate. This gives it several functions depending on the position of all the parts. It can still be used like a normal tailgate, dropping down at the push of a button or using the key fob.
