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!"

New car market raining on convertibles' parade

Whether fitted with soft or hard folding lids, today's droptops are better than ever for year-round motoring. Advancements in power top mechanisms, sealing, aerodynamics, structural rigidity, rollover safety and creature comforts like heated and cooled seats mean that modern convertibles are more versatile and better to drive than ever before. Yet the segment's sales took a dive during the recession and haven't come back, Automotive News reports.
Part of that is because automakers are looking at today's more sensible buyers and simply not developing as many new models, and that lack of fresh iron is curbing sales. AN cites R.L. Polk data which notes that only about one percent of new vehicles registered in the US last year had tops that folded. Back in 2009, it was 1.4 percent, and it was 2 percent in 2006. All-in, some 151,636 convertibles were registered in 2012. That's more units more than were registered in each of the past three years, but the market has also grown as the economy has picked up speed, and as a percentage of new vehicles purchased, convertible sales are lagging.
Thus far in 2013, the Ford Mustang is America's top-selling convertible, with 6,421 units registered through the end of April, followed by its rival, the Chevrolet Camaro, at 4,751 units. The Volkswagen Beetle isn't far behind, with 4,305, but from that point, it's a steep drop off to the fourth-place Mercedes-Benz SL-Class and its 2,380 sales.

Crowdsource funding push on to save historic Ford buildings

Detroit has no shortage of old, abandoned buildings, both within the city and in the surrounding communities. Few, though, have the historical significance of the old Ford Highland Park facility. Home to the very first moving assembly line, Highland Park was designed by the legendary Albert Kahn, and was one of the homes of the Model T.
Now, the Woodward Avenue Action Association is attempting to buy both the 40,000-square-foot admin building, which is located off the historic Woodward Avenue, and an 8,000-square-foot garage. The WAAA's goal is to convert the buildings into an automotive heritage center. The Detroit News spoke to the interim director of the WAAA, Deborah Schutt, who commented, "[Metro Detroit has] not been very good at telling our own story. So we've decided, let's pull everything together and tell our story."
The WAAA made an offer of $550,000 to buy the two buildings, and has $400,000 from the Michigan Department of Transportation and another $15,000 from the Michigan Economic Development Corporation. It's trying to raise a further $125,000 through crowd-sourcing, starting a campaign called "Five Dollars A Day," after old Hank Ford's $5-per-day wage for line workers.
