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!"

Dodge Challenger Hellcat X is 805-hp worth of charity [w/video]

Donating to charity is good for the soul. You feel good and help out those in need, and while you should donate out of the goodness of your heart, there's nothing wrong with getting something in return. That's doubly true if that something (or somethings) happen to run on gasoline... a lot of gasoline. For just $3 (plus $40,000 in taxes), you could park not one, but two high-powered Mopars in your driveway. The big item, of course, is the world's most powerful Dodge Challenger Hellcat. Dubbed the Hellcat X after the XF6F, a twin-charged US Navy prototype that evolved into the Hellcat fighter from World War II. Its 6.2-liter, supercharged V8 has been supplemented by a turbocharger, boosting output to 805 horsepower. Because, you know, 707 just wasn't quite enough. It should be noted that the Hellcat X isn't a production model – Fiat Chrysler isn't going to be putting a twin-charged Hemi into production – but that it's a one-off job built for the 2015 Chrysler Nationals at Carlisle. Joining the Hellcat X is a handsome, black 1970 Challenger 440 R/T. Complete with a four-barrel carburetor (yeah, we were hoping for a Six Pack, as well), a pistol-grip shifter, and menacing black paint, this exact car was the star of 2012's "Revolution Reborn" television spot. And if this car's on-air claim to fame isn't enough, rest easy knowing you're the owner of just one of 100 black 440 R/Ts produced in 1970. Now, single tickets do start at $3, although there are larger bundles available, including a $5,000, 6,000-ticket package. Proceeds from the drawing, which is being put on by Dream Giveaway, will go towards New Beginning Children's Home charity, which issues grants to everything from the National Guard Educational Foundation to Mothers Against Drunk Driving.

The mad genius of killing the Dodge Dart and Chrysler 200

Sergio Marchionne isn't crazy. At least not with respect to the recent announcement that Fiat Chrysler Automobiles will cease production of the Dodge Dart and Chrysler 200. Instead of crazy I'd call this CEO ruthlessly pragmatic, and perhaps short-sighted. The latest revisions to FCA's most recent five-year plan tell some truths about the company's finances. In other words, it can't afford to build mainstream sedans. With only 87,392 units sold in 2015, the Dart is an also-ran in the segment. The axe falls easily there - Chrysler hasn't had a compact-car hit since the second-generation Neon. The 200 isn't so cut and dried: Last year sales increased 52 percent, and the 177,889 total for 2015 is more than those for the Subaru Legacy and Kia Optima. But looking at the overall FCA picture the Chrysler 200 has to go, at least from a short-term perspective. The vehicles that make big money – Ram trucks; Jeep's Cherokee, Grand Cherokee, and Wrangler – can't be made fast enough. FCA can't afford to idle the 200's Sterling Heights, MI, assembly plant to cut back on inventory when other plants are running flat out. It seems crazy to throw away 265,000 sales, but FCA is leaving money on the table by not building more profitable vehicles. The Wirecutter's Senior Autos Editor (and former Autoblogger) John Neff agrees. "As bold as it looks from the outside, he's really making a safe bet that their money is better spent on designing better and building more crossovers and trucks. He's probably right about that." But according to Jessica Caldwell, Executive Director of Strategic Analytics at Edmunds, "FCA's strategy of eliminating the Dart and 200 might be short-sighted if gas prices were to rise and Americans, once again, flocked to small vehicles. FCA must have plans to expand the lineup of small SUVs and position them as small-car alternatives in terms of price and fuel efficiency for this strategy to make sense." FCA's latest announcement focuses mainly on the profitable brands and nameplates. There's hardly a mention of Chrysler, Dodge, or Fiat. And future planning is where the plot holes appear. This realignment cuts dead weight from the product portfolio, but FCA's latest announcement focuses mainly on the profitable brands and nameplates. There's hardly a mention of Chrysler, Dodge, or Fiat. So what's Sergio up to? David Sullivan of AutoPacific thinks Marchionne is still looking for another CEO to hug.
