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!"

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.

Are you a new Ford Mustang SVO? [w/video]

When Ford announced that its 2015 Mustang would arrive with a 2.3-liter EcoBoost four-cylinder engine, three letters came to mind: SVO. While Ford hasn't said a word regarding the rebirth of a Mustang SVO model, this latest set of spy shots shows us something very, very interesting. Allow us to explain.
The Mustang prototype in these photos looks very similar to the GT500 test cars we've spotted before - same bulging hood, aggressive front fascia and air vents aft of the front wheels. What's different, however, is around back. Have a look at the exhaust, and note that instead of the GT500's usual quad pipes, two of the exhaust outlets have been capped off.
Our spies point out that these exhaust outlets could be closed for some sort of emissions testing or another engineering reason, but it's also important to note that the engine and exhaust notes of this car sound completely different from earlier GT500 prototypes. We've got a video below that compares the two.
