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!"

Chrysler killing off the 200 Convertible, Dodge Avenger

When Chrysler rolled out the first-generation 200 to replace the Sebring range in 2010, it included replacements for both the sedan and the convertible. The Sebring Coupe, however, was left out of the mix. And now that the second-generation Chrysler 200 is descending upon us, Auburn Hills is paring things down even further. But this time, it's the convertible that reportedly isn't making the cut. Shame, too, since the rendering above shows what could have been quite an attractive droptop.
As our compatriots at Edmunds point out, sales of the convertible model accounted for less than five percent of overall Chrysler 200 sales, and at those numbers, the considerable cost of engineering a new drop-top couldn't be justified. With the Toyota Camry Solara and Volkswagen Eos also gone from the market (well, the VW isn't gone quite yet), the discontinuation of the Chrysler 200 Convertible leaves the affordable convertible segment largely to the sportier likes of the Ford Mustang and Chevy Camaro and smaller European offerings like the Mini Cooper and VW Beetle.
The Chrysler 200 Convertible isn't the only derivative being left behind with the new model: so too is the Dodge Avenger. That will leave a glaring hole in the Dodge lineup, with nothing to bridge the gap between the compact Dart and the larger Charger. Whether the Dodge brand has any plans to replace the Avenger with another model, not to be based on the 200, remains to be seen.

2013 Dodge Dart gets all Moparized

Last year, Chrysler announced it would be offering more than 150 Mopar parts and accessories on the 2013 Dodge Dart, and we got a look at some of these parts firsthand at the Chicago Auto Show. Showing off all the optional parts at once would surely create a gaudy monstrosity, so Chrysler chose to equip this particular Dart GT with just a handful of Mopar goodies, which still gave the car a nice and tasteful custom look that is available straight from the dealership (and with a full warranty, too).
Decked out in a factory color called Header Orange Clear Coat - also a very appropriate show car hue - this car added exterior styling parts such as the vented, carbon fiber hood, the bolt-on front chin spoiler and a matte black decklid spoiler. Looking inside the car, you'd think the red-accented interior is part of the Mopar parts bin, too, but this is actually what the standard Dart GT cabin will look like when it goes on sale.
