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!"

Mopar teases four of 'nearly 20' SEMA Show concepts

Yesterday it was Chevrolet. Today, Mopar has dropped some SEMA knowledge, releasing a quartet of teaser images that give us some indication of what kind of cars, trucks, and crossovers Fiat, Chrysler, Dodge, Jeep, and Ram will be showing in Las Vegas. Like Chevy, Mopar's concepts utilize both production and concept accessories, although Fiat Chrysler has gone a bit more indepth on at least one of its concepts. Immediately, the most tantalizing teaser is the one shown above. Yes, that's the back of a Challenger, and aside from the bright orange accents on the gray body, you should take notice of the badge mounted on the spoiler – yes, that says "GT AWD." To be honest, such a vehicle wouldn't be a huge shock, as both the Challenger's LX platform-mates, the Dodge Charger and Chrysler 300, are offered with all-wheel-drive options. Still, adding such a vehicle to the production cycle would give Dodge a leg up on the rear-drive only Ford Mustang and Chevrolet Camaro. Aside from that concept, FCA has also released teasers of a Ram-based concept, a 300-based concept, and what we're guessing is a Fiat 500X. We can't wait to see what the actual Fiat concept has to do with kiteboarding. As for the 300 and Ram, there's not a lot of hints on what sort of styling details they'll contain. The Chrysler has additional LED accents and what we're guessing is matte blue paint, while the Ram is based on a Hemi-powered 1500 with Rebel styling cues. This is just a very tiny sample of Mopar's final SEMA roster, which include "hundreds" of parts. There should also be a total of 20 vehicles covering all four former Chrysler Group brands, as well as Fiat. Naturally, we'll have plenty to report on each vehicle once the SEMA show kicks off in the next couple weeks.

Will Dodge limit 2015 Challenger SRT Hellcat to 1,200 units?

With over 700 horsepower on tap and a price tag barely over $60k, Dodge appears on paper to have a winner on its hands with the new Challenger SRT Hellcat. But if you want to get your hands on one, you may have to act quicker than this most powerful of muscle cars covers the quarter-mile.
That's because, according to our compatriots over at Edmunds, Dodge may limit production - in the first year, at least - to just 1,200 units. That would amount to barely a quarter of the Challengers that Dodge moves each month, and would also mean only one Hellcat for every two Dodge dealers in the US - which could lead to some serious contention over which stores and which customers can get their hands on the ultimate Challenger.
Reached for comment, SRT spokesman Dan Reid told Autoblog that "there is no plan to limit production of the Challenger Hellcat," echoing the words of Dodge CEO Tim Kuniskis who told Edmunds: "We don't know what the market demand is." Which doesn't mean that it won't restrict production, but doesn't mean that it will, either. It just hasn't decided yet - or announced any such decision, at any rate - over what will be the final allocation strategy for what could be a game-changing muscle car. That is, at least, until new versions of the Mustang and Camaro come along in pursuit of Dodge's bragging rights...
