NHTSA investigating Ford Fiesta for faulty door latches

The National Highway Traffic Safety Administration has opened a preliminary investigation on the 2011-2013 Ford Fiesta because the regulator has received 61 complaints from drivers, including one claim of an injury, about the doors on the subcompacts failing to latch and sometimes even flying open while driving. NHTSA has estimated that the problem could affect as many as 205,000 vehicles.
NHTSA is still gathering further data about the problem, but looking at the complaints so far, both front and rear doors appear to be potentially involved with the alleged failures. Among the reports, there are 12 claiming that the door opened while driving. Several also indicate the "Door Ajar" warning illuminating during this problem. The one purported injury happened when someone attempted to shut the door, and it bounced back.
Ford spokesperson Kelli Felker told Autoblog via email, "We are cooperating with NHTSA on this investigation, as we always do." Scroll down to read the report from NHTSA.

Ford Focus ST checks into Jay Leno's Garage

In a change of pace from the high-end vehicles that often appear in Jay Leno's Garage, Ford sends its hottest hatchback (in the US, at least), the 252-horsepower Focus ST, to be featured on Leno's show. Accompanying the five-door hatch is its chief engineer, Jamal Hameedi.
Riding on stylish 18-inch wheels with summer tires and with a spoiler that doubles as a lunch tray, Hameedi and Leno walk us through the finer points of what makes the ST special, which also includes bigger brakes, torque vectoring, a manual transmission and, of course, 252 hp and 270 pound-feet of torque from the 2.0-liter EcoBoost four-cylinder engine, which is made possible by 21 psi of turbocharged boost.
Watch the video below to see what Leno thinks of the global Focus ST.

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!"
