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!"

These are the five most ridiculous attacks on the Chevy Volt [w/videos]

It's been a long, strange trip for the Chevy Volt from the time when the now-odd-looking concept version (above) was introduced at the 2007 Detroit Auto Show to today. And now, General Motors announced that the second-generation Chevy Volt will make an appearance at the 2015 Detroit show in January. This debut represents a victory for GM with what has easily become the most politicized car of the 21st Century. There are plenty of reasons for someone to criticize the Volt, but what's amazing is just how much anti-Volt energy has been spent not on things like the styling or how the EREV setup is not as efficient as a pure-EV powertrain. As we wait for more official information on the new Volt, we thought it would be fun to go back and look at some of the most wildly incorrect reporting and strangest attacks on the Volt from the archives. There is so much good stuff out there, it was hard to pare the list down, but these are our five favorites. Amazingly, they're not all clips from Fox News. Check 'em out below. 5. GM Is Going To Stop Making The Chevy Volt In The US Do you remember when GM was about to move Volt production to China? Well, yeah, this was reported back in early 2012 when a GM executive mentioned that the automaker would get benefits of building the Volt in the places where it sells them. This was spun into a story of GM taking Obama bailout money and then running to China. The Blaze was not happy: "Given the fact that Federal government helped itself to millions and millions of taxpayer dollars under the pretense that it was going to combat high unemployment by creating 'green jobs,' it would seem that moving research and development (and possibly manufacturing) overseas is slightly, well, counterproductive." Well, of course, that never happened. There's no way to say that GM will never build a version of the Volt in China, but the news we hear rumors of these days is that GM is going to move production of more Volt parts (specifically, the motors) to Michigan from overseas. 4. The Chevy Volt Is A Fire Trap There has never been a Volt that just spontaneously lit up while driving down the road. Yes, there were Volts that caught on fire. Yes, that's a scary thing. But there has never been a Volt that just spontaneously lit up while driving down the road. These were crashed test vehicles with destroyed batteries and plugged-in vehicles that were not the cause.

Here's why automakers roll out those Texas-themed pickup trucks

Every year, automakers with a full-size truck link make a big show of the Texas State Fair, usually involving a reveal of a new model. Sometimes they show a whole new truck, and other times a special edition centered on the Lone Star state. While some people might write this off as a quirk of the industry, others might be wondering, "What's the big deal with Texas?" As it turns out, part of the big deal with Texas is big truck sales. According to Dave Sullivan, product analysis manager at AutoPacific, Texas buys more trucks than any other state in the country. It's not a small margin either. Edmunds.com, one in five trucks sold in the US are sold in Texas. The state also accounts for 15 percent of the country's large truck sales, which is more than twice that of California, the second largest truck market in America. Even when you break down sales only in Texas, trucks are a huge piece of the pie - Sullivan says that a quarter of new vehicle sales in Texas are trucks. One in five trucks sold in the US are sold in Texas. But it's not just sales that make truck builders give attention to Texas. As Sullivan explained, "Pickups are life in Texas." Both he and Hugh Milne, marketing and advertising manager for the Chevy Silverado line, said that trucks are key fixtures in Texas society, as both work trucks and luxury vehicles (or Texas Cadillacs as Milne called them). Milne said Texas is so important in the truck market that if you want to be successful in the rest of the country, "you've got to be successful in Texas." As for the State Fair, it has become a prime location for reveals in part because of the importance of the Texas market and because of how big the fair is. Milne also revealed that the State Fair also hosts its own auto show, so it's an ideal venue for a vehicle introduction. So there you have it. Why do truck builders obsess over Texas? It's because Texas obsesses over trucks. When you have one market that loves your product that much, you give it the attention it deserves.
