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!"

2015 Fisker-Galpin Rocket Quick Spin [w/video]

There is no shortage of fast Mustangs these days. Roush and Saleen will tune your ordinary 'Stang into something really special. Ford itself offers hot coupes like the new Shelby GT350. Don't even get me started on the endless aftermarket catalogs full of bolt-on whats-its and performance upgrades. Standing out within the huge crowd of tuned Mustangs is hard to do. But you'll definitely notice this one. "I always wanted to do a Mustang," Henrik Fisker told me as we walked toward his latest creation, the Rocket, parked outside the Inn at Spanish Bay in Pebble Beach, CA. The man knows a thing or two about design, after all. He penned the BMW Z8, as well as the Aston Martin DB9 and V8 Vantage. But this Rocket is, well, ugly. The rear end isn't totally terrible, and those 21-inch wheels are sort of cool, but taken as a whole, it looks like it swallowed something it doesn't like the taste of. But beauty is in the eye of the beholder – or perhaps, the creator – so we'll let Mr. Fisker explain why the car looks the way it does. See the video below for his brief design walkaround. If you can get past the looks, there's a world of performance to unleash, thanks to the boys at Galpin Auto Sports – the same folks responsible for the GTR1 I drove last year. The Mustang's 5.0-liter V8 gets a 2.9-liter Whipple supercharger that improves output to 725 horsepower (the torque figure isn't available), and the car's suspension has been thoroughly reworked to help put all that grunt to the ground. It's very good, yet very familiar. Let me explain. Driving Notes Like the stock Mustang, it's really easy to drive. The car fires up with a growl, you move the shifter into first gear, and the action of engagement is as solid as it is in the normal 5.0-liter car. Both the clutch and throttle have a progressive action, so it's super easy to launch the Rocket (sorry). Once you get going, there's a ton of power to unleash. It doesn't smack you in the face right up front, though – the power delivery is smooth and linear. Easy to manage, too, thanks to that slick six-speed manual transmission. Credit Ford (and Getrag) for making a manual that's able to handle so much extra grunt. That said, the Rocket feels like your typical fast Mustang. It goes like hell in a straight line and there isn't a ton of steering feel. Galpin retuned the electronic power-assisted steering, but it's still too light considering the added power of the car.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.
