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!"

2013 Dodge Dart gets brace of new special edition models

After almost a year on the market it, it is becoming more clear to Dodge how customers like to option out their Darts, so the automaker has combined popular features into three special edition packages and sweetened the prices. Start with a standard 2013 Dart and add either the SXT or Limited "Special Editions" or Rallye Appearance Group, and you'll save yourself a lot of box checking.
The $595 Dart SXT Special Edition takes the trim just above the base model and adds a new grille, dark-tinted headlights and projector fog lights, LED racetrack taillights, cruise control and audio controls on the leather-wrapped steering wheel. The Limited Special Edition starts with the top-end model and adds a power sunroof, heated front seats and steering wheel, dual-zone climate control and Nappa leather seats among other features, for $1,810.
The Rallye Appearance Group (pictured) is a package for the SXT, and it blacks out the front fascia, throws on 17-inch wheels and some badging for $395. The new special editions are reaching dealers now and could help the Dart's sales to further improve after a slow start. You can find out more about them in the press release below.

Defiance Dodge Charger, saving Earth from aliens isn't clean work [w/video]

You'll be forgiven for not having heard about the TV show Defiance - it actually hasn't aired its first episode yet. The new science fiction show about an alien war against Earth in the near future seems like a perfect fit for the SyFy channel, and, apparently one that Dodge saw as a slick marketing opportunity for its Charger sedan.
Here in Chicago, Dodge has given a large corner of its show stand to the Defiance Charger, a car that won't be skipped by any Mad Max fans in attendance at this year's show. The Charger boasts one hell of a gnarly patina under a confusingly welded cage of tube steel, as well as window bars, a grille guard in front, and big, knobby truck tires. There aren't any obvious guns or turrets on the outside of the vehicle, so we can only hope that the characters driving it go well-armed.
Look for the Charger to make its star turn in Defiance when the series premieres on SyFy on April 15 at 9:00 PM EST. Also, there's said to be a Defiance video game in the works, too, so you may get a chance to steer the burly Dodge for yourself. Find a trailer for the show, below, as well.
