Next-gen GMC Terrain teased looking chiseled in AT4 trim

The next-generation GMC Terrain is coming soon, as GMC just dropped its first teaser of the redesigned compact crossover. It makes sense that GMC is re-doing the Terrain now, as its Bowtie-badged equivalent, the Chevrolet Equinox, was just completely redesigned, too. GMC teased the new Terrain in its most rugged AT4 trim, and the look sure is a bold one from this partial front-end view. From the headlights to the upright grille and chiseled hood, this Terrain is looking more Yukon- and truck-like than ever before. Expect the AT4 version seen here to mirror the Equinox Activ trim from an equipment perspective by adding all-terrain tires wrapping smaller-diameter wheels for a legit boost off-road. It may also feature a unique front bumper for improved approach angle. As for the interior, spy photos have shown that it will differ significantly from its Chevy cousin. Those photos show a tall, vertically-oriented screen that takes its cues from the GMC Acadia. There isn’t much in the way of details provided by GMC, but the company does let on that the new Terrain – this will be its third generation – will have a “bolder, more assertive design” throughout the vehicle. Based on the Equinox, we're expecting it to get the same turbocharged 1.5-liter four-cylinder with 175 horsepower and an eight-speed automatic transmission. All-wheel and front-wheel drivetrains will likely be offered as well. A full reveal isnÂ’t planned until “later this year,” leading us to believe this Terrain will be a 2025 model year vehicle just like the Equinox is. ItÂ’s also scheduled to launch after the refreshed Yukon, which GMC says is coming along later this year, too. Related video:

2020 Chevy and GMC HD truck spy shots reveal LED lighting

With Chevy and GMC's 1500 series pickups just starting to roll into dealerships, our attention naturally turns to the Heavy Duty 2500 and 3500 series trucks. We've seen these HD trucks testing already, but thes latest spy photos give us our first good glimpse of the two HD trucks' headlights through some translucent camouflage, and their designs appear very interesting and quite different from each other. The 2020 Chevrolet Silverado HD looks to be getting a striking set of LED lights that flank the grille. A previously released teaser image of the truck shows that the front lighting elements are split by a bulky wing that branches out from a big, upright chrome face, and both top and bottom units seem to incorporate LED slashes. If you look closely at the images, you can easily make out the Chevrolet script cut into the grille's top edge. Amidst a bevy of Chevy test trucks was one lone GMC model in a dually configuration, and the Sierra HD also appears to have some LED accent lighting up front. Unlike the boomerang-shaped Chevy LEDs, GMC's version sports a shoulder-like right angle of light bars. Assuming these are production-level lighting units, it seems the Sierra HD will stick pretty close to the face of GMC's latest light-duty pickup truck. We're still waiting for confirmation on what range of powertrains will be available in GM's next-gen HD trucks, but we're sure there will be both gasoline- and diesel-burning engines on the ordering sheet. We expect to hear official details on the trucks sometime soon.

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!"
