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!"

2021 GMC Canyon Denali shows its new grille

GMC showed us its new 2021 Canyon AT4 pickup at the beginning of the year. We got a few details on the "more upmarket" top-tier Denali trim coming next year, but we've been missing good photos of the article until now. The more upmarket part rings true when it comes to the front fascia of the the 2021 Canyon Denali, achieved at the cost of a busyness compared to the 2020 model. That's because designers bent the set-square lines on the current trim into angles and flared edges from top to bottom, adding more prominent textures along the way. The comparison shot in the gallery above reveals all,  the "exclusive heroic grille design" — really, that's GM's name for it — the heart of "a more distinctive and sophisticated design that has become synonymous with Denali," according to Holt Ware, the brand's head of exterior design. Inside, the luxury trim offers a new and exclusive open pore ash wood for accents, a Cocoa/Dark interior treatment, heated and cooled front seats, aluminum trim, and embroidered headrests. There's wholesale change coming for the entire Canyon lineup, but we need to wait for GM to officially announce the 2021 pickup to codify everything properly. The trim walk has changed, from Canyon, SLE, All Terrain, SLT, and Denali to Elevation Standard, Elevation, AT4, and Denali, and we're still wondering what this might to do the $650 Elevation Edition cosmetic package. The bargain basement models have also gone away, putting the new MSRP floor $4,200 above the 2020 model to go along with other price increases dotted throughout the lineup. GM Authority says Canyon production won't be delayed by the coronavirus lockdown, so production should begin n Wentzville, Missouri, in a few months. Related Video:    

2018 GMC Sierra Denali 1500 Drivers' Notes | Chrome cowboy

No matter how much automakers want to charge for trucks, it seems there will be a market. Ford, Ram and GM all have trucks that can push well over $60,000, something that would sound unbelievable even 10 years ago. That brings us to the 2018 GMC Sierra Denali, GM's top dog in the pseudo-lux truck segment. It's packed with tons of goodies and features, but it's starting to feel a little long in the tooth. Still, GM trucks are some of the best selling vehicles in America, so it seems customers don't mind the age. Associate Editor Reese Counts: I've said it before, but I'm not a big truck guy. Give me a Colorado or Tacoma over any of the full-sized behemoths rolling off assembly lines today. Still, I do enjoy taking one home on occasion, especially one as comfortable and well appointed as this Sierra Denali. There's leather and wood and contrasted stitching throughout. The problem is that it's all a veneer over what's becoming an extremely dated truck, though a new one is on the horizon. There's one big thing that truly bothers me about this truck: no keyless entry or ignition. Don't get me wrong, I have no problem doing things the old-fashioned way, but when literally every other competitor at this price has keyless as standard equipment, the fact that GMC (and Chevy for that matter) still require you to pull out a fob and stick a key into an ignition is really glaring. It has to have something to do with the platform, as GM makes plenty of vehicles that don't require a key. One thing that doesn't feel dated is the ride and performance. This truck is equipped with GM's Magnetic Ride Control, and it works wonders for the Sierra's comfort. It would be even better if it wasn't wearing some gaudy 22-inch wheels, but it's still better than a lot of trucks out there. The powertrain, too, is a nice bright spot. The eight-speed automatic is smooth and never feels lost in the hunt for better fuel economy. The 6.2-liter V8 feels strong, and power comes on smooth and easy. Ford's EcoBoosts may win on fuel economy, but there's nothing like a big, burly V8. Senior Editor, Green, John Beltz Snyder: Despite the massive amounts of guilt I feel every time I put my foot to the accelerator, big trucks — something of which I used to steer well clear — are beginning to warm up on me. That being said, others have made more of an impression on me than this Sierra.
