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!"

Marchionne on Alfa's US return, Dodge Dart's powertrain weakness and minivan plans

As a reporter covering an auto show, the one opportunity you never want to miss is going to the Sergio Marchionne press briefing.
"This undertaking to bring Alfa back is a one-shot deal... We are not going to do this twice."
There just aren't that many real characters left in the auto industry. Marchionne, who sits atop both Chrysler and Fiat, is not only one of the smartest execs in the business, but also the most frank. Herein, a sample of the quotable always-sweatered executive:

2015 Dodge Challenger SRT Hellcat gets brace of new videos

Yesterday's big announcement focusing on the new Dodge Challenger SRT Hellcat had plenty of stuff going for it - information, pictures and the rabid enthusiasm that always accompanies such an eagerly anticipated reveal. What it was lacking, though, was a proliferation of videos of the new model.
Sure, yesterday's news came with one clip, but today, Dodge has come through with five videos. We've arranged them in what we think will be the most entertaining order, covering the powertrain, before moving on to exterior and interior design, then on to a full CGI dissection of the SRT Hellcat before capping things off with a piece on the non-supercharged Challenger SRT392.
Take a look below for all five videos, then head into Comments and let us know what you think.
