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!"

Coal-rolling Ram dually does tandem beer-shooting burnout with ATV in bed

Sometimes a video comes around that just makes you shake your head in disbelief. Take for example these guys from Nebraska in their dually diesel flatbed Ram, doing a smoky burnout. Lighting up the tires is nothing new, but these folks take things a step further by having another guy on an ATV in bed that is also smoking the tires. Finally, people are sitting on a couch in the bed taking the whole show in, as beer cans shoot out of the stacks.
There have been several stories recently about the scourge of rolling coal, i.e., diesel trucks modified to lay down a thick, black smoke screen, sometimes for vaguely political reasons. Whatever your opinion is on it, breathing in this much nasty stuff isn't exactly great for your health. Of course, it turns out that burning rubber is pretty awful, too. Both diesel and tire emissions contain cancer-causing Group 1 carcinogens. Combine them with the cigarette smoking here, and these guys are an oncologist's nightmare. Scroll down to take it all in for yourself. Warning, there is a little explicit language.

NHTSA investigating Chrysler for airbags, ignition switches

Chrysler is being targeted by the National Highway Traffic Safety Administration in a pair of actions that focus on over 1.2 million Jeeps, minivans and crossovers.
The first is a "preliminary investigation" that focuses on an airbag issue afflicting the Jeep Commander built in model years 2006 and 2007 and Grand Cherokee from 2005 to 2006. In total, 700,000 vehicles could potentially be affected. It's not entirely clear what the airbag issue is, with The Detroit Free Press simply stating that the restraint systems in the affected Jeeps may be "faulty."
The other investigation is what's called a "recall query" and it covers a problem that General Motors should be familiar with. In this case, there could be a problem with the ignition switches of 525,000 vehicles, ranging from 2008 to 2010 Chrysler Town & Country and Dodge Grand Caravan minivans, to the 2008 to 2010 Dodge Journey crossover. Again, it's not entirely clear what sort of behavior prompted the 32 complaints that NHTSA has received on these vehicles.
