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.

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!"

Mopar '13 Dart will roll into Chicago next week

We think this officially counts as a tradition. Every year going back to 2010, Mopar has rolled out a limited edition version of a popular product from the Chrysler Group portfolio. First it was the Mopar '10 Challenger, then the Mopar '11 Charger, then last year's Mopar '12 300, and this year it will be the Mopar '13 Dart, which will make its official world debut next week at the 2013 Chicago Auto Show.
Limited in number to just 500 units, the Mopar '13 Dart is no mere appearance package, though the demeanor of the Dart will be murdered out with a gloss black finish, gloss black 18-inch wheels, a set of Mopar blue stripes and a mean-looking Mopar ground effects kit. Likewise, the interior is touched up with leather seats (a blue one for the driver and black hides for the passengers), gloss black and black chrome trim, blue accent stitching, a sport pedal kit and other Mopar interior accessories.
Turning our attention back to the mechanical bits, the Mopar '13 Dart comes with the car's most powerful engine, a turbocharged 1.4-liter MultiAir four (shared with Fiat 500 Abarth) that's paired with a manual transmission. Those big, black wheels get wrapped in low profile 225/40R18 performance tires, and keeping everything in check is an upgraded brake kit with slotted rotors. The steering has also been calibrated for performance, the suspension lowered seven millimeters, and the exhaust tuned for better engine breathing.
