Dodge Challenger R/T Shaker and Mopar '14 Challenger up the retro appeal

The reborn Dodge Challenger might be getting a bit long in the tooth, having been on the market in its current form since 2008, but Chrysler isn't going to give up on its brutish, full-size two-door just yet. For this year's SEMA Show, the Challenger will be getting a new Mopar edition, as well as a retro-cool shaker hood on the 5.7-liter, Hemi-equipped R/T models.
As we mentioned last night, the Shaker Package will cost $2,500, but includes the Super Track Pak (new steering rack, brake linings, upgraded shocks and 20-inch Goodyear Eagle F1 Super Car tires), a $595 option on its own. The shaker hood result in a performance bump of any kind, but the blacked-out, pop-up scoop is a nifty feature that hasn't been seen on a production car since the Ford Mustang Mach 1 in the early 2000s.
The Mopar '14 Challenger (pictured right) follows the cues of previous Mopar Editions, which have included the 2010 Challenger, 2011 Charger, 2012 300 and 2013 Dart. Only 100 Mopar '14 Challengers will be produced, and they'll include the new shaker hood, Mopar's distinctive blue graphics and wheels, and whatever is pilfered from the accessory catalog.

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!"

NHTSA investigating Ram 1500 models for rear differential failure

The National Highway Traffic Safety Administration is investigating Fiat Chrysler Automobiles and its Ram brand following a number of reports regarding the 2005 Dodge Ram 1500 pickup. According to 15 consumer complaints, the trucks' rear differential locked up while in other cases, the driveshaft separated at its connection to the diff.
Nearly half of the reports claim the truck was traveling at or above 50 miles per hour, while two consumers reported that the diff lockup/driveshaft separation sent their pickups into a spin. Most troubling, though, is that consumers reported little to no sound indicating there was a problem with their truck.
We reached out to Ram for additional information, such as how many vehicles may be affected or what equipment might be fitted that could cause the issue. Unfortunately, the company wasn't willing to elaborate on specifics.
