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!"

2014 Dodge Durango leaks ahead of NY rollout

Even though Chrysler will reportedly discontinue the Dodge Durango after the current model's lifespan - said to be around 2016 - that isn't stopping the automaker from improving its full-size, three-row SUV. The vehicle won't debut at the New York Auto Show until tomorrow, but images are already leaking out ahead of the embargo lift, and they show that the 2014 model is getting even more aggressive styling to go with more technology inside and out.
Dodge limited its early press shots of the new Durango to just the R/T trim level, but this new look adds a meaner look to this model with more dramatic projector-beam headlights along with a "floating" crosshair grille and a restyled fascia. At the rear of the Durango, LED racetrack taillights show a family resemblance to the Charger and Dart, while a new rear fascia adds to the styling while also allowing for an integrated trailer hitch.
On the tech side, the instrument panel looks to have been redesigned to include a standard seven-inch thin-film transistor (TFT) gauge cluster, and it also appears as if Chrysler's well-liked UConnect system has been updated with the 8.4-inch touchscreen found in other Chrysler vehicles. The 2013 model's conventional console shifter has been replaced by a rotary knob for gear selection, suggesting that there are transmission changes afoot as well. We'll have more details when the silks slide off this big boy tomorrow, so stay tuned.

2015 Dodge Charger priced from $27,995, Hellcat from $63,995*

Ladies and gentlemen, let's get the most salient bit of information out of the way right off the bat: $63,995*. That's the amount of money Dodge dealers will be asking for (at the very least, naturally) for a 2015 Charger Hellcat (*plus $995 for destination on all pricing figures). That rather reasonable sum will bring home its buyer a 6.2-liter Hemi V8 engine boasting a supercharger to post such gaudy figures as 707 horsepower and 650 pound-feet of torque, leading to a top speed of 204 miles per hour to go along with an NHRA-certified quarter-mile time of 11.0 seconds.
With that out of the way, the rest of the 2015 Dodge Charger pricing information breaks down as follows: $27,995 will deliver a sedan with a 292-horsepower 3.6-liter Pentastar V6 engine, mated to an eight-speed automatic transmission. Moving up one step of the ladder nets the buyer an SXT model with the same engine, but a nicer chunk of technology and optional equipment for a $2,000 premium. All-wheel drive adds another $3,000. Hemi V8-powered R/T models now boast an eight-speed transmission bolted to the same well-loved 370-horsepower engine as before, for a base price of $32,995.
The SRT 392 model that had hitherto been the top-performing Charger brings with it an asking price of $47,385 while bargain hunters can equip a Charger R/T Scat Pack machine with that same 485-horsepower 6.4-liter Hemi, albeit with somewhat less posh interior bits and pieces, the removal of the 392's adjustable suspension and hi-po wheel and tire package for $39,995.
