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!"

2022 GMC Sierra 1500 Denali gets Super Cruise and an upgraded interior

The 2022 GMC Sierra 1500 is getting Super Cruise! Exclamation point required, because this is exciting news. Cadillac has been the sole owner of Super Cruise at GM from the start, and though we knew it was coming to the Hummer EV, we didn't know a fast-selling full-size pickup would be getting the technology. GMC says it will launch Super Cruise on the 1500 Denali, which is the most expensive and luxurious trim of the Sierra. It’s scheduled to arrive for the 2022 model year, but GMC qualifies that by saying “late model year 2022.” That means itÂ’s probably coming right toward the end, with 2023 scheduled as the first full year of Super Cruise in the Sierra 1500. GM also claims that the version of Super Cruise coming to the Sierra is capable of towing. Yes, hands-free towing, folks. WeÂ’re a little antsy, too. The tech is the same as the newest generation of Super Cruise coming in the Cadillac CT5 and CT4. ItÂ’s an improved version with more capability than the first-gen system that won AutoblogÂ’s Technology of the Year award a couple of years ago. Questions still remain to be answered, though. GM hasnÂ’t said anything about what it will cost on the Sierra 1500. WeÂ’re also left in the dark when it comes to other Sierra 1500 trim levels; and what about the Silverado 1500? It makes sense that GM would give the Sierra Super Cruise first, but itÂ’s certainly compatible with the Chevy version of the truck now, too. As for other GMC products, GM is quiet on when theyÂ’ll be blessed with Super Cruise. The redesigned Yukon would be the most obvious candidate being the flagship product, but GM says the program timing worked out best to launch on the 2022 Sierra, not the Yukon. ItÂ’s likely that the SUV will be updated with the system in the near future. Besides Super Cruise, GMCÂ’s photo also reveals that the 2022 Sierra is getting a fully digital instrument cluster. ItÂ’s surely an optional item, but could very well be standard on Denali. GM has flipped the speedometer and tachometer to opposite sides, but their digital versions still have that straight-edged GMC look to them. You can see the Super Cruise graphic in the center, and all the gauges are dropped down to the bottom of the display. But wait, thereÂ’s more. The photo also shows the beginnings of a totally new interior design, different from both the current Sierra, standard Yukon and Yukon Denali interiors. ItÂ’s immediately and obviously different everywhere we look.

2020 GMC Sierra 1500 Interior Driveway Test | Still lagging behind

GM has caught nothing but grief for the interiors of its full-size pickups since they were redesigned. Some of it is about perspective. Ram blew everybody away with the new 1500’s interior, but it's not like the Ford F-150 is embarrassed by it. Chevy and GMC are. Even a top-shelf Sierra Denali doesnÂ’t live up to the luxurious environment its price tag would promise.  The trim of Sierra we're testing is an AT4, though. ThatÂ’s the light off-roading version of the Sierra thatÂ’s mechanically the same as the Silverado Trail Boss we recently reviewed. Looking at the interior from a pure functionality standpoint, the Sierra is perfectly fine at performing its truck duties. The seats are wide, flat and comfortable. It has huge armrests on both sides so you can stretch out as much as your truck stretches the boundaries of the road (seriously, this thing is huge). All the buttons in the center stack are well-labeled, easily found and big enough to stab away at without hitting the wrong one. It even has a volume and tuning knob. Yeehaw!  But look at the design. And the styling, or lack thereof. ItÂ’s plain and lacking in imagination. The whole center stack is just one big slab of black plastic, and the only splashes of color or style to distinguish it visually are bits of silver surrounding knobs and bits of gray surrounding air vents. That's certainly not enough to make it attractive. There are token pieces of "wood" inserted on Denali models, but they're almost hidden away along the center console and doors.  The screen looks as if itÂ’s scrunched into the top of the stack due to the vents curving in on both sides, making it look smaller than its perfectly acceptable 8-inch size. That just makes it more obvious that GM doesn't offer something to challenge the gigantic 12-inch optional screen on the Ram 1500. Not good, because size does matter when it comes to trucks, even if it's measured in a touchscreen's inches rather than engine displacement. LetÂ’s not discount how good all of the tech is in the Sierra 1500, though. GMÂ’s infotainment software that runs on the screen is glitch-free and runs like lightning through screens and menus. The performance is impressive, and of course both Apple CarPlay and Android Auto are on board.
