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!"

25,000 Jeep Grand Cherokee, Dodge Durango SUVs recalled over brake feel

Chrysler has announced that it is recalling over 25,000 Jeep Grand Cherokee and Dodge Durango SUVs from several markets over concerns about brake feel under hard braking. The affected models are from the 2012 and 2013 model years, although the actual dates of production aren't available. 18,700 are in the US, while 825 are in Canada, 530 are in Mexico and a further 5,200 outside of North America.
According to a statement, Chrysler was informed of the issue by a component supplier for the Ready Alert Braking system, which primes the brakes in anticipation of an emergency stop. A component in the system was restricting the flow of brake fluid too much.
As Chrysler is quick to point out, the way the brakes functioned was in compliance with regulations and there are no reported cases of drivers losing braking power. Instead, the issue rests with what Chrysler calls a pedal feel that "was not consistent with customer expectations." So it would seem Chrysler is being proactive and fixing a problem not because there's a legal issue at work, but simply because it doesn't feel the way the manufacturer wants it to. Well done.

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.
