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!"

Dodge Durango SRT is much cheaper than Jeep Grand Cherokee SRT

Dodge has finally announced availability and pricing for the 475-horsepower Dodge Durango SRT. The Detroit-built SUV will start at $64,090 and hit dealer lots toward the end of the year. It's not a cheap SUV by any means, but you get a lot for the money: including 470 pound-feet of torque, and all-wheel-drive. Plus it has three rows of seats and can tow 8,600 pounds. Not only that, but it's basically the best performance SUV deal from the Fiat-Chrysler group. The Grand Cherokee SRT, with the same engine, costs almost $4,000 more at $67,990. The Durango SRT outperforms the Grand Cherokee in several key areas, too. It's 0.4 seconds quicker to 60 mph and manages to break into the 12s in the quarter-mile whereas the Grand Cherokee is stuck in the mid-13-second range. The Durango can also tow an extra 1,400 pounds, has an extra row of seats, and has more maximum cargo space with the seats. So unless you just really love the Jeep look and brand, the Durango SRT seems like the logical choice. And if either still isn't potent enough, just wait for the upcoming Grand Cherokee Trackhawk. Regardless of your choice of SRT vehicle, you'll still come away with a really powerful SUV, as well as a day of instruction at the Bob Bondurant driving school in Arizona.

Why the Charger Hellcat can't be ordered with a manual transmission

Fans of truly irreverent amounts of horsepower will find lots to love in the form of the 2015 Dodge Challenger and Charger Hellcat models. Both of them send 707 ridiculous horsepower to the rear wheels; the only question is whether you want your absurdity delivered with two or four doors. Oh, and whether or not you want the option of a manual transmission.
If you prefer rowing your own gears, the choice is made for you; there is no manual gearbox option available on the Charger Hellcat, or any Charger model at all, for that matter. Wonder why? Well, besides the fact that almost nobody - sorry, clutch fans, but it's true - would choose to buy a Charger with a manual transmission, that is? The answer, according to an industry insider in a post written on Jalopnik's Opposite Lock forum, is the floorpan.
It's probably not a surprise to most of our readers that the Dodge Challenger and Charger share a large portion of their chassis structure, which is codenamed LX at Chrysler, but there are still some significant differences under the skin due to the shorter wheelbase and two-door coupe bodyshell of the Challenger, as opposed to the sedan shape of the Charger. One of the differences is the floorpan, the huge chunk of sheetmetal that makes up the floor of the car and props up such essential items as the car's seats.
