Chrysler recalling 644k more Dodge Durango and Jeep Grand Cherokee SUVs over brakes

Early last month, we reported on Chrysler issuing a preemptive, proactive recall for about 25,000 units of the Jeep Grand Cherokee and Dodge Durango. The issue revolved around a brake system that wasn't causing any actual problems, but delivered an unsatisfactory brake feel, so Auburn Hills called in a good 25,000 of SUVs around the world, including 18,700 in the United States.
Now Chrysler, having apparently determined that the brake problem on its sport utes is actually much bigger than it initially realized, has drastically broadened the scope of the recall. As a result, the National Highway Traffic Safety Administration has issued a recall for precisely 655,354 examples of the Grand Cherokee and Durango, covering the 2011 through 2014 model years. In addition, Chrysler is recalling 42,380 units in Canada, 21,376 in Mexico and 159,685 overseas.
The problem which Chrysler found revolves around the brake booster, whose center shell has been found to be subject to corrosion, allowing water to get into the brake system. That water in turn could freeze, preventing the brakes from working as well as expected.

Dodge idles Viper production again at Conner Avenue

You've got to hand it to Dodge for having the gumption to put the original Viper into production in the first place. It was, after all, much more of an emotional decision than a practical one, and a move which saw the first production V10 engine placed in a road car - long before the advent of the Lamborghini Gallardo, Audi R8, Porsche Carrera GT or Lexus LFA, not to mention the other Ford, BMW and Volkswagen Group models that used such engines.
It's now been 22 years since the first Viper entered production and the Viper still rolls on several generations later, but we're sad to say that courageous decision has not always been met with overwhelming sales success. In fact parent Chrysler was forced to idle the Conner Avenue plant where the Viper is made back in April due to slow sales. And while production resumed again as planned on June 23, it apparently didn't do the trick.
As a result, Chrysler corporate communications chief Shawn Morgan revealed to Autoblog that the assembly line has been shut down again for another two weeks. The line was up and running for nearly two full work weeks from June 23 until the holiday weekend that started on Thursday, July 3. But instead of coming back online today as planned, it's been idled again for the weeks of July 7 and 14. That means it will be July 21, at the earliest, before the serpentine supercars start slithering down the assembly line at Conner Avenue again. Once it does, however, production is set to resume at the same pace it was before the shutdown.

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!"
