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!"

Nissan Leaf sales get January jump as Chevy Volt trends downward

The cold January sales dip hit both the Nissan Leaf and the Chevy Volt last month, but when compared 2014 to 2013's first-month-of-the-year sales totals, one of the two early plug-in vehicles obviously came out on top. The top Leaf market also shifted away from Atlanta for the first time in months. Last year, the Leaf sold just 650 units in January, but it managed to move 1,252 last month, a 92.6-percent increase over 2013 but a big drop from the 2,529 sold in December 2013. Paige Presley over at Nissan told AutoblogGreen that the Leaf has now broken sales records for 11 months straight and that, "we see unique seasonality with some December pull-ahead demand based on federal and state tax incentives." The number one Leaf market also shifted away from Atlanta for the first time in months, moving back to San Francisco. That change could be short-lived. "We had some inventory constraint issues early in the month in Atlanta with end-of-year demand depleting stock," Presley said. "By the time we resolved that, the weather hampered sales." There was not as much good news on the Chevrolet front. Last month, the Volt sold 918 units, down from 1,140 in January 2013 and 2,392 in December 2013. It also marks the first time the Volt has sold in the three-digit range since January 2012, when it sold 603 copies. That string of solid months means that the plug-in hybrid has a roughly 12,000-unit lead over the EV since the two cars brought plug-in vehicles back to the mass market all the way back in December 2010. We will have our full report of January's green car sales up soon.
