NHTSA closes probes on Jeep Grand Cherokee, Ford Freestar and Mercury Monterey

The Detroit News reports the National Highway Traffic Safety Administration has officially closed its investigations into 2012 Jeep Grand Cherokee, 2004-2005 Ford Freestar and Mercury Monterey models. The separate probes found no issues that pose safety concerns. NHTSA began investigating certain Grand Cherokee SUVs over complaints that power steering hoses could detach during operation, thereby increasing the risk of a vehicle fire. Of the 24 reports of failure, none alleged smoke or fire in the engine bay, and Chrysler has since modified the power steering cooler assembly to reduce the likelihood of the failure.
Meanwhile, certain Ford Freestar and Mercury Monterey vehicles garnered a government probe after receiving complaints that the models were equipped with faulty scissor jacks. The agency had received six reports of the jacks failing or causing injuries, including one incident that resulted in a fatality. But NHTSA says the jack failure rate is similar to those found in other vehicles. In those six cases, the government agency found the jacks were being used for something other than changing a tire, and investigators could not determine whether the emergency brake was set or the rear tires were properly chocked.

Hertz goes Dutch with Ford Focus ST-H

Want to take a performance car for a ride? Hertz can make that happen. Spin by your local rental location (depending, of course, on availability) and you can take out a Dodge Challenger, Ford Mustang, Chevy Camaro, even a Corvette as part of the Adrenaline Collection. Hertz's Dream Cars lineup even includes Porsches and AMGs. But the really interesting stuff is what you can't get anywhere else: cars built specifically for Hertz.
Back in 1966, Hertz had Ford cook up a special run of Mustang GT350H models in back with gold stripes. It became an icon in and of itself, and in 2008 Hertz had a new batch of Shelby GT-Hs made. Earlier this year, Hertz contracted Penske to deliver another fleet of specially-built Mustangs you can rent. But if your travel plans include a trip to the Netherlands, Hertz has a completely different type of specially-prepared Ford on offer for you.
Back in August, Ford delivered a couple of Focus STs made specifically for Hertz in Holland. Now it's expanded that fleet even further. The Ford Focus ST-H features the same 252-horsepower 2.0-liter turbo four (and everything else) as the standard Focus ST, but gets that signature black exterior with gold stripes and a black leather interior with Recaro buckets. So in case a trip to Amsterdam doesn't hold enough thrills, now you can throw a hot hatch into the mix as well. Scope out the press release (in Dutch - isn't that weird?) below.

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!"
