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!"

Junkyard Gem: 2005 Chevrolet Aveo LS Sedan

The story of Daewoo in North America took some interesting plot turns over the decades. First we had the 1988-1993 Pontiac LeMans, a rebadged Daewoo LeMans. A bit later, Daewoo began selling cars under its own nameplate here, with the Lanos, Nubira, and Leganza available for the 1999-2002 model years. Then Daewoo fled the continent and left warranty service of those cars in the hands of Manny, Moe, and Jack. With GM taking over Daewoo Motors after Daewoo's bankruptcy, we got some Daewoos with Suzuki badges here— the Verona and the Reno— while Chevrolet began selling the South Korean-built Daewoo Kalos as the Aveo for the 2004 model year. This car may not be a gem in the sense that you would want to own one, but it's a gem of automotive history and thus deserves its place in this series (especially because it's one of the rare 5-speed cars sold here). Many (maybe even most) of these cars ended up in the hands of rental-car companies and other fleet users, but we can tell from the three-pedal setup that this car went to a non-fleet buyer. We've had a couple of these cars compete in the 24 Hours of Lemons, where I work as a dignified and respected race official, and they've been amazingly quick on a road course in the hands of good drivers. Power came from this 103-horsepower Opel-designed four displacing 1.6 liters. The Nubira and Lanos got versions of this engine on these shores, too. The LS was the top trim level for the Aveo in 2004, so this car got air conditioning and a halfway decent audio system (by 2004 standards). The seat fabric is industrial-grade stuff, which would have held up well under the steady drip and/or torrents of bodily fluids coating the interiors of rental cars. The 2004 Aveo LS started at $12,045, which comes to about $16,675 in 2020 dollars, so it was a lot of commuter-appliance for the price. The following generation of this car became the Chevrolet Sonic, beginning with the 2012 model year. You can still buy a new Sonic, and the inflation-adjusted price is nearly identical to that of the original AveoÂ… though you might want to move fast if you really want one, because Daewoo stopped selling the Kalos in South Korea not long ago. If you want the rarest member of the Aveo family available in North America, find yourself a hen's-teeth Pontiac G3, the short-lived Pontiac-badged version. Speaking of the G3, here's the way it broke the hearts of gas pumps around the world.

Surprise! GM putting aluminum in next-gen pickups

Last month, General Motors launched a series of ads touting the benefits of steel over aluminum – specifically, with regard to the Chevy Silverado versus the Ford F-150. (Kind of. We're not sure what a grizzly bear has to do with anything.) We took issue with the ads, with editor in chief Mike Austin saying they "reek of insecurity, and distract from the Silverado's strengths that could be used for positive advertising." But what bothers us more, is that yet another report surfaced claiming anti-aluminum GM will indeed use the weight-saving material in its next-generation fullsize trucks. On Tuesday, GM announced a $877-million investment for its truck plant in Flint, MI. But Reuters says that huge overhaul is because the trucks will use "substantially different equipment than the tools GM uses today." The report specifically states, "People familiar with the company's plans say GM's next-generation pickups and SUVs will make use of various materials, including aluminum and lightweight steel, to shed weight and gain fuel efficiency to meet tougher federal standards." The Silverado already uses a few aluminum components in the engine and hood, and if more widespread use will help GM build its best fullsize trucks ever, then that's great. Honestly, we have no reason to doubt that aluminum will be used in the next Silverado and GMC Sierra. We just hope GM remembers that nothing is ever truly deleted from the bowels of the Internet when it launches the subsequent "look how great aluminum is!" campaign.
