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!"

Ford Fiesta RS with 250 horsepower mooted

We know Ford is unveiling a new Focus RS on February 3, and it's heavily rumored to arrive brandishing an all-wheel-drive powertrain and as much as 350 horsepower. The folks at Ford Performance have also promised they are working on at least 12 models through 2020, and that still leaves a lot of time to get additional exciting vehicles out the door. One of those could be an RS version of the Fiesta, according to Evo. An RS take on the latest Fiesta would obviously need substantial boosts in both power and handling ability to warrant the work over the current top Fiesta ST (pictured above), which is already one of our favorite cars. Evo speculates that the 1.6-liter turbocharged four-cylinder could be tuned further, possibly up to about 250 horsepower, and the high-performance hatch might even take some inspiration from the Fiesta WRC rally car with an all-wheel drive system. An unnamed Ford spokesperson remained cagey about the chances for the pint-sized hot hatch to Evo, though. "We can't say anything at this moment, but we have promised to produce 12 performance models in the coming years. We'll leave it for you to decide whether that includes a Fiesta at this moment," the source said to the magazine. Evo doesn't expect a launch across the pond until at least 2017, if it actually happens. Of course, there's the lingering question of whether such a niche project would work in the US. In Europe, the Fiesta RS would challenge similarly diminutive speedsters like the Volkswagen Polo R and Audi S1, but true competitors of an equivalent size here would be much more scarce. In fact with 250 hp, the hotter Fiesta could provide unwelcome competition within Blue Oval showrooms for the Focus ST.

2014 Ford Fusion to get 1.5L EcoBoost three-cylinder?

Just one year after launching the all-new 2013 Fusion, Ford is reportedly set to alter the sedan's powertrain lineup with the addition of a new 1.5-liter turbocharged three-cylinder EcoBoost engine. A member of Blue Oval Forums apparently got their hands on the ordering guide for the 2014 model year Fusion, and this 1.5-liter mill is set to be introduced with late availability.
This lines up with other news about the Chinese-market Mondeo being offered with a new 1.5-liter EcoBoost - a derivative of the 1.0-liter triple that will come to North America under the hood of the Fiesta (note: the 1.0 is also offered in the current Euro-spec Mondeo). In the Chinese application, the larger three-pot engine produces 177 horsepower and 177 pound-feet of torque, which is very close to the current 1.6-liter inline-four's output numbers of 178 hp and 184 lb-ft.
What's interesting, however, is that the 1.6-liter engine will reportedly still be offered in the Fusion, but only with the six-speed manual transmission. The smaller 1.5-liter EcoBoost will only be mated to a six-speed SelectShift automatic, and will feature start/stop. This means that while the 1.5 is slightly down on power compared to the 1.6, it could easily improve fuel economy numbers, allowing the Fusion to regain the title of having the best mileage in the segment, likely besting the 38 miles per gallon of the Nissan Altima. Currently, the Fusion 1.6 is rated at 23 mpg city and 36 mpg highway.
