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!"

General Motors and EVs: No stranger to firsts, but where's the leadership?

2015 is already shaping up to be the year of "affordable, 200-mile EV" concepts. Nissan and Tesla have each been talking about them for some time, the latter promising to unveil its Model 3 at the North American International Auto Show in January before balking when the time came. Instead, Chevrolet beat them all by unveiling the Bolt concept at the same event, followed shortly thereafter with suggestions of a 2016 launch – potentially offering the first nationwide EV with anything close to that range. It was the ballsiest EV-related move General Motors has made in a quarter century. But will it remain so? Exactly 25 years before the Bolt rolled up onto the turntable, then-Chairman Roger Smith unveiled GM's last ground-up EV concept, the even-more-unfortunately-named Impact, at the Los Angeles Auto Show in January 1990. A few months later, he surprised most of his colleagues by announcing its intended production in honor of Earth Day. It was the first modern foray into electric vehicles for the US by any automaker, one that was rewarded by the State of California with what is now known as the Zero Emissions Vehicle mandate. The program not only forced other automakers into competing with Roger's pet project, but inspired all of them to fight it like small children against bedtime. Some years later, the drivers themselves weighed in, with a biting documentary about that obstinance and the leadership it cost both GM and the country. Within months, GM was first back into the fray of plug-in vehicles. Many criticized the company for starting with a PHEV rather than jump straight back into EVs. The choice wasn't totally out of the blue – even EV1 was meant to be followed by a PHEV. And especially on the heels of Who Killed the Electric Car?, some skittishness was understandable: even a successful EV would invite a "we told you so" public reaction, underscoring their mistake in ending the EV1 program. If a new EV didn't do well, they'd be convicted in the public eye as serial killers. All while seeking a federal bailout. For all the flak, the resulting Chevy Volt was and is a better car than GM has ever gotten credit for. But the company seemed to grow weary of having to overcome its varied past, and while the current owners remain happy, much of the stakeholder and community engagement that so effectively built early goodwill and sales growth faded not long after launch. Marketing has been spotty in both consistency and effectiveness.

Thanks for keeping us on our toes, Detroit Auto Show [w/poll]

Here at Autoblog, we love unexpected debuts at auto shows – and judging by our Detroit Auto Show comments and traffic, you do, too. Surprise reveals have been fewer and farther between in recent years with so many ways for vehicles to be teased or leak out, but this week's show has been a revelation. More to the point, it's been a series of revelations, with automakers from around the globe successfully delivering a brace of concept and production surprises. It's made our jobs a lot more exciting and challenging this week, and even though it's actually more work to react and run-and-gun when the sheet is pulled on a surprise reveal than it is to publish an already-written embargoed story, we've had more fun covering this show for you than any domestic show in memory. We hope you've enjoyed the surprises along with us. To that end, borrowing the words of an unnamed automaker PR flack, we'd like to thank the following automakers for enduring "mountain of antacids" and that "creeping sense of paranoia" necessary to keeping ones' wares totally under wraps until the sheets are pulled off the sheetmetal: Buick Avenir concept Chevrolet Bolt concept Ford GT concept Ford Mustang Shelby GT350R Ford F-150 SVT Raptor Hyundai HCD-15 Santa Cruz concept And while we're at it, we'd like to throw in an shout-out to Detroit's substantially revised and revitalized Cobo Center, and in particular, the redone Michelin media center, which is arguably the single best accommodations for writing show stories that we've encountered on the entire international circuit. Well done, everyone. Thank you, and keep the surprises coming. Auto News Detroit Auto Show Buick Chevrolet Ford Hyundai Volvo 2015 Detroit Auto Show
