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!"

Road & Track samples rare 1995 Ford Mustang Cobra R

The modern performance variant of the Ford Mustang enjoys a long, illustrious history. While well-known examples like the Boss 302, Shelby GT350, and Shelby GT500 get all the attention, the modern versions of these cars may not have been possible had it not been for the three generations of the Cobra R, sold in 1993, 1995, and 2000. Limited to just 250 examples, the second-generation model wasn't as rare as the Fox-body Cobra R that preceded it, but they were still pricey and difficult to acquire. Customers were required to hold a competition license in order to take delivery, and prices were roughly equivalent to $59,000 in today's money. As Road & Track tells it, neither of those facts were a handicap – Ford sold its entire roster of 1995 Cobra Rs in just five days. RT's Jack Baruth managed to score a drive in an extremely low-mileage example of this now-vintage track star. He delivers an interesting look into the way a performance car from two decades ago behaves in today's world, and finds that despite its age, the 1995 Cobra R is still "a true sweetheart." Check out the full feature over at Road & Track. Related Video:

Ford cuts production at 5 plants, has big backload of cars including Mustang

DETROIT — Ford said on Tuesday it plans to idle five North American vehicle assembly plants for a total of 10 weeks to reduce inventories of slow-selling models. The plants affected include three assembly plants in the United States and two in Mexico, the company said in a statement. The vehicle models include the Ford Fusion and Lincoln MKZ midsize sedans, the Ford Focus compact car, the Lincoln Continental and Ford Mustang, Ford Fiesta and the Ford Transit van. Ford said the Cuautitlan assembly plant that builds the Fiesta would be idled for three weeks. The Hermosillo, Mexico plant that builds the Fusion and MKZ and the Flat Rock, Michigan, factory that assembles Continentals and Mustangs will be idled for two weeks each. The Michigan Assembly plant that builds the Focus will be idled for one week, and the Kansas City assembly line that builds Transit vans will be down for two weeks. Ford did not give dates for the temporary shutdowns. The factories involved employ more than 15,000 people, according to Ford's website. The company did not say how many of those workers would face temporary layoffs. As of Sept. 1, Ford had 111 days' worth of unsold Mustangs, 87 days' supply of Fusions, and a 103 days' supply of Transit vans, according to Automotive News. Dealers had enough unsold Lincoln Continentals to last 162 days. Automakers aim for 65 to 70 days of inventory of most models. Ford and rival General Motors have wrestled most of this year to rein in high inventories of passenger cars as consumers have shifted to buying pickup trucks and sport utility vehicles. Production cuts slice into revenue, but also could help the automakers avoid deeper price cuts on vehicles they can sell.
