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 previews new C-Max ahead of upcoming debut

Looking at a Ford Focus? These days you can get it as a five-door hatch, a four-door sedan, or... that's all. European buyers don't even get our sedan, but they do get a wagon. And while the three-door hatch, two-door coupe and two-door cabrio have long since ended production, buyers around the world can also get the company's larger C-Max. And now, like the Focus upon which it's based, Ford is preparing to roll out a new version.
The tall wagon (or small minivan, depending on your perspective) is being treated to what Ford says is "an extreme makeover." Details to accompany the teaser image above remain few and far between, but following the spy shots we recently posted, it looks destined for some of the same visual updates as Ford rolled out on the 2015 Focus, with "even more refinement, practicality and technology."
Like the Mercedes B-Class, which is only available Stateside as an EV, American buyers can only get the C-Max in electrified form, either as the C-Max Hybrid or C-Max Energi. Overseas buyers, however, will be able to choose from a range of powertrain options and two wheelbase lengths - the longer of which boasts seven seats and the Grand C-Max name. (Remember when Chrysler did the same with its minivans?) Both are set to debut on September 17, so watch this space. After that, we'll expect to see it on display at the Paris Motor Show.

Did a US automaker blow the whistle on Hyundai, Kia fuel economy issue?

In all of the most hotly contested mainstream segments of the motoring universe, the difference of one mile per gallon averaged on a widow sticker can mean the difference between a sale and a walk-off - to say nothing of two or three mpg. So, when Hyundai and Kia were forced to reveal that many of their 40-mpg ratings were actually 38s and 37s, well, it made for big news.
It also, conceivably, made for a competitive disadvantage immediately, when the Korean automakers' products were being shopped versus the guys down the block. And it's that disadvantage that makes a recent story from Automotive News so juicy.
AN is reporting that Margo Oge, former head of the Environmental Protection Agency's Office of Transportation and Air Quality, got a tip in 2010 that Hyundai/Kia were "cheating" to get its impressive fuel economy numbers. The tip, said Oge (who retired from the EPA this past September), came from a senior vice president from a domestic automaker. The source was credible enough for Oge to launch an audit of the Hyundai figures, which ultimately lead to the debacle that we reported on a few months ago, and that the Korean company has been trying to bounce back from ever since.
