2021 GMC Canyon AT4 Road Test | The everyday tool

Bold take: The GMC Canyon is the most well-rounded midsize truck. Admittedly, “well-rounded” is a lukewarm compliment, but the Canyon does nearly everything well. It is not the flashiest, which is undeniably the Jeep Gladiator. Or the most comfortable, which is the Honda Ridgeline. But for those seeking a midsize truck that looks like a truck, drives like a truck and has a solid interior, the Canyon is the right formula. We would test the 2021 GMC Canyon AT4 for a week and find that itÂ’s pleasant, capable and sturdy off-road. We would haul a bookshelf in the bed, get dirty during a woodsy soft-road jaunt and pile up the miles running around town. In short, itÂ’s exactly what most need in a midsize truck.  The AT4 model is new for 2021, and it replaces the All-Terrain model, a move GMC is rolling out across its lineup. The AT4 adds an off-road-tuned suspension with hill-descent control, beefy 31-inch Goodyear Wrangler DuraTrac tires wrapped around 17-inch aluminum wheels, standard four-wheel drive with locking rear differential and a transfer case skid plate. The AT4 punches up the CanyonÂ’s appearance with red tow hooks, dark chrome elements and a bigger grille thatÂ’s similar to the SierraÂ’s. The Canyon Denali, which was also refreshed for ‘21, is showier, but the AT4 trim feels cooler with its understated off-road vibes. Considering this, we head out for an afternoon drive along a familiar route through DetroitÂ’s northern suburbs. The Canyon is a solid daily driver. The 3.6-liter V6 rated at 308 horsepower and 275 pound-feet of torque is widely used in General Motors vehicles. ItÂ’s powerful and actually sounds pretty good — even throaty — in GMCÂ’s midsize truck. Our passengers are surprised to be pulled back in their seats during hard acceleration, and the eight-speed automatic transmission is well-calibrated for the many jobs the Canyon is called upon to perform. This powertrain, standard in the AT4 and Denali trims, is a step up from the 2.5-liter inline-four and six-speed auto offered on the lower models. ItÂ’s worth it. The 2.8-liter Duramax diesel is an option on higher-spec Canyons, and its 369 lb-ft of torque is tantalizing. For everyday use, take the V6. Our tester with the gasoline V6 and four-wheel drive can tow as much as 7,000 pounds, has a maximum payload of 1,609 pounds and has respectable fuel economy of 17 mpg in the city and 24 mpg on the highway.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

2024 GMC Hummer EV SUV First Drive Review: Still impressive, even out of its element

SAN FRANCISCO – Our first experience with the GMC Hummer EV in any form was spent in an environment clearly ideal for such a vehicle. That first drive of the production-ready truck was in Arizona, a place with large, open freeways and rocky, desert terrain. Notably, they were areas that could showcase the Hummer's strengths: enormous power and acceleration, a lack of trees or narrow lanes to hinder its size, and sufficiently rocky terrain to demonstrate its remarkable off-road abilities. So it was particularly strange that the media's first experience with the Hummer EV SUV would involve the tight streets and twisty mountain passes of San Francisco and Napa Valley, locations that certainly would seem to put the Hummer on the back tire. In some ways they certainly did, but at the same time, they revealed the Hummer is surprisingly capable out of its element, and maybe even a good fit for the area. The start of our driving time involved leaving downtown San Francisco and heading up Highway 29 to Napa where GM had set up a number of demonstrations like those at the truck first drive, and where our winery hotel was. In the birthplace of Tesla, where Models of all letters and number are ubiquitous, the monster black Hummer definitely stood out. And not just for its sheer size: it is the technological flagship of General Motors, perhaps the most traditional of American car manufacturers. On the other hand, the locale also felt appropriate given that flagship status, from its flashy instrument and infotainment displays, to its acrobatic suspension and steering systems. This is as good a time as any to go over what makes the Hummer EV SUV different from the truck. Obviously it has a solid roof over a cargo area instead of an open bed. It's also the smaller of the two giants: total length is 20 inches shorter (excluding the spare tire) and the wheelbase is 8 inches shorter. That pays a few dividends in maneuverability both on and off road. The turning circle of the SUV is 1.7 feet smaller, at 35.4 feet, which is almost 3 feet tighter than that of the Chevy Bolt EUV. The breakover angle is also improved by 10.6 degrees (49 at max ride height) and the departure angled by 2.2 degrees (34.4 at max ride height). Though the bed is gone, the interior cargo space is certainly spacious, with maximum capacity of 81.8 cubic feet with the rear seats folded perfectly flat into the admittedly high load floor.
