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 Chevrolet Silverado LT Trail Boss adds 3.0-liter diesel option

Order books just opened for the 2022 Chevrolet Silverado, which, in case you hadn't heard, is almost unchanged compared to the 2021 Silverado. The overhauled Silverado and GMC Sierra that we caught in spy shots several times last year and were expected to launch this year have been delayed. Until that pickup gets here, Chevrolet and GMC will add "Limited" to the names of the Silverado and Sierra. Fleet guides for next year's truck show the official model name as Chevrolet Silverado 1500 LTD. There are a few interesting features coming next year, though, like the Multi-Flex tailgate joining the options list for Silverado HD trucks. GM Authority also reports that the 2022 Silverado LT Trail Boss adds the 3.0-liter oil-burner with 277 horsepower and 460 pound-feet of torque as a third engine option, which should be a big treat for the off-roading crew. Whereas the GMC Sierra AT4 already offers the 3.0-liter diesel, the Silverado LT Trail Boss only offers the 5.3-liter and 6.2-liter V8s, both bolted to GM's ten-speed automatic transmission. Then there's the Custom Trail Boss that adds the 4.3-liter V6 as an option, and it and the 5.3-liter V8 only get 6-speed automatics. At the moment, Silverado trims that offer the Duramax charge a $1,045 for it over the 5.3-liter V8. If that gap holds true for next year, the diesel will just about evenly split the price difference between the LT Trail Boss with the 5.3 and the 6.2.   Elsewhere in the range, Driving.ca said Canadian fleet guides show the 4.3-liter V6 and lower-spec 5.3-liter V8 with Active Fuel Management (AFM) instead of Dynamic Fuel Management (DFM) disappearing from next year's base Silverado WT. To clarify, AFM only shuts off half the cylinders in certain conditions, whereas DFM constantly adjusts how many cylinders are firing all the time. As it stands, that would leave the 2.7-liter turbo four-cylinder as the only engine option. However, those other two mills were the only ones left in the lineup that shift through a six-speed transmission, making it possible that they'll rejoin the options list with at least two more gears to choose from. It's not clear if GM will sell the Limited models alongside the majorly upgraded 2022 Silverado. The automaker did just that a few years ago, selling the previous-gen truck as a Limited trim alongside the then-new, current-gen. It certainly wouldn't be the only company to do so, either.

Kurt Busch to shake and bake (again) in Ricky Bobby car at Talladega

Kurt Busch will channel Ricky Bobby for another NASCAR race, this time driving a Wonder-sponsored Chevrolet SS, in this weekend's Camping World RV Sales 500 at the Talladega Motor Speedway. Unlike past tie-ins, though, there's actually an element of sponsorship here (the "Me" car was done when Busch was running on a team without sponsorship).
It was arranged by Flower Foods, the new owner of the Wonder brand. Wonder was part of the bankrupt Hostess company, which temporarily exited the US market 2012, and set off the Great Twinkie Shortage.
Busch has made something of a habit of channeling characters from famous racing movies, most recently running Tom Cruise's City Chevrolet livery from Days of Thunder in a Nationwide Series race earlier this year. Busch kicked off his movie-inspired antics, though, at Talladega in 2012, when he raced El Diablo's ("It's like... Spanish for like a fighting chicken") "Me" car complete with a cougar on the hood. He even went so far as to channel the lovable idiot that is Ricky Bobby during the race, dropping a few catchphrases about macchiatos and slingshots.
