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!"

Ford wants smart cruise that's speed and grade sensitive

Ford is working to make adaptive cruise control even smarter and more economical for future vehicles. The automaker now has a patent (pdf link) on a system to use information on the grade of the road, traffic data, and a driver's preferences to eke out better fuel mileage over a journey. This solution would essentially put a little hypermiling right into a model's software. The Blue Oval's patent refers to this tech as "route navigation with optimal speed profile," and the system starts by splitting the way to the driver's ultimate destination into many smaller pieces. Each one is analyzed based on GPS data, and traffic info is also constantly updated. Based on the occupants' preferred travel time, all this info is combined to figure out the most efficient speed for each leg of the journey. All of these calculations are actually more than the car's computers can handle, so some of the math is offloaded to a cloud-based network. According to Ford, some of the benefits come when tackling hills while diving. Maintaining a single speed when going up and down steep grades isn't the most efficient method, but current technology can't easily make the necessary adjustments. This system uses the GPS data to adapt the vehicle's speed and leave the situation with better fuel economy. Ford is currently making major investments into autonomous driving technology and has some prestigious partners. While the patent documents don't specifically mention the optimal speed profiles for driverless vehicles, they seem like a natural fit. Over the course of an entire trip, the fuel economy gains would likely be even greater than over a few miles on a relatively flat interstate.

Shelby to auction 2012 GT350 No. 1 in Vegas

With Shelby preparing to wind down production of its brutal GT350, a 624-horsepower Mustang that's meant to go up against the Roush Stage 3 in the world of tuned Ford ponycars, the Las Vegas-based tuner is looking to give back to one lucky customer. It'll auction off the very first GT350 ever produced, at the 2013 Barrett-Jackson auction in Las Vegas, a three-day event that runs from September 26 through September 28.
The GT350 is a monster, with a 5.0-liter, supercharged V8 that's been tuned well past 600 horsepower in a time when Ford's own Shelby-branded GT500 barely reached 550 horsepower. The GT350 is much louder than Ford's effort, too, both visually and audibly. The wide body look isn't what we'd call conventional, but on a car that sounds and goes like this, something extreme is needed. According to Shelby American's vice president of production, Gary Davis, "Carroll was very excited about the new wide body option, so that was included on this car. It's the first 2012 GT350 serial number from our anniversary year. It is a very special car." Wilwood brakes, a massaged suspension, and some very fat, sticky tires add to the Shelby experience.
This particular GT350 will be lot number 750, and will cross the Barrett-Jackson stage on Sunday, September 28.
