2016 Ford Focus RS mule spotted on US soil

Okay Ford, this is what we like to see. One of our intrepid spy photographers has captured a vehicle that we weren't even sure would see the light of day - the next Focus RS. While this is pretty clearly a mule based on the current Focus ST, as our spy points out, there are a number of giveaways about this hot hatch's true nature.
Indication number one that all is not right with this Focus is the heavily camo'd front fascia, which has been completely reconfigured for duty on the RS. It boasts significantly larger grilles that are meant to accommodate what is likely the 2.3-liter, turbocharged four-cylinder that's destined for the 2015 Ford Mustang. Considering that, then, we can expect around 300 horsepower and 300 pound-feet of torque from the hottest of Foci, although it's entirely possible that the production model could climb even higher, to around 330 hp.
The front fascia tweaks are complemented in the back by a modified rear bumper, which fails at hiding a pair of exhaust tips quite unlike the standard Focus ST's center-exit exhaust. Other obvious changes include the wheel/tire/brake package on this particular car. Larger 19-inch wheels are shod in super-sticky Michelin Pilot Super Sport tires in 235/35/19 while the brakes feature what we think are four-piston calipers, possibly from Brembo, up front.

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!"

NHTSA closes Ford F-150 EcoBoost acceleration probe

Typically when we report on the findings of an investigation from the National Highway Traffic Safety Administration, it's because the government body has discovered a safety issue and prescribed a recall. In this case, however, NHTSA has closed an investigation into a reported performance deficit without ever getting to the recall stage.
The issue revolves around the Ford F-150 - specifically those equipped with the 3.5-liter EcoBoost engine - of which some 360,000 were built in the 2011, 2012 and 2013 model years. After receiving an initial 95 complaints, NHTSA opened an investigation last May - almost a year ago - into the reported issue of reduced engine power under hard acceleration. The agency has since received a total of 525 such complaints, and Ford itself reported receiving over 4,000.
Together, NHTSA and Ford determined that the problem resulted from cylinders misfiring, an issue itself stemming from water getting into the charge air cooler (CAC) mated to the turbochargers. In particularly humid or rainy conditions, water was found to get into the CAC, causing some of the cylinders to misfire, which in turn triggered the ECU to disable those cylinders in order to protect the catalytic converter from damage.
